We’re talking buttery potato rounds topped with sweet, golden onions and melted Swiss cheese. The potatoes are tender on the inside, slightly crispy around the edges, and covered in the most delicious combination of savory flavors.

And the best part? You only need four ingredients!

I’ve always been a fan of easy appetizers that look impressive but don’t require a long list of ingredients or complicated preparation. These Swiss Onion Potato Bites are exactly that!

For this recipe, I like using baby gold potatoes because they have a naturally buttery flavor and creamy texture. They’re also the perfect size for turning into little appetizer bites.

The potatoes are sliced into thick rounds and partially cooked before going into the oven. This helps them become tender in the center while developing lightly golden edges during baking.

But what really makes these potato bites special is the topping!

Thinly sliced yellow onions are slowly cooked in butter until they’re soft, sweet, and golden brown. They’re then spooned over the potatoes and topped with freshly shredded Swiss cheese.

The sweet onions, buttery potatoes, and melted cheese are such a delicious combination!

Ingredients

Here I explain the best ingredients for this Swiss Onion Potato Bites recipe, what each one does, and substitution options. For the exact ingredient measurements, see the recipe card at the bottom of this post.

Baby gold potatoes – I recommend using 1½ pounds of baby gold potatoes for this recipe. These small potatoes have a naturally buttery flavor and creamy texture that makes them perfect for oven-baked appetizers. Their small size also makes them easy to slice into individual rounds. You can substitute small Yukon Gold or red potatoes if needed. I recommend choosing potatoes that are approximately 1½-2 inches wide, so the finished bites are easy to pick up.

Yellow onion – you’ll need one large yellow onion, thinly sliced. I love using yellow onions because they have a nice, neutral flavor that becomes wonderfully sweet as they caramelize. You can also use sweet Vidalia onions if you prefer an even sweeter topping. I recommend slicing the onion thinly so it softens evenly and cooks down into golden, tender strands.

Unsalted butter – you’ll need 3 tablespoons of butter, divided between the onions and potatoes. The butter adds rich flavor and helps the onions become golden brown as they cook. It also gives the potato rounds a delicious buttery coating before baking. I recommend using unsalted butter, but salted butter will also work if that’s what you have available.

Swiss cheese – the star ingredient that brings everything together! You’ll need 1½ cups of freshly shredded Swiss cheese. Swiss has a mild, slightly nutty flavor that pairs perfectly with sweet caramelized onions. I recommend purchasing a block of Swiss cheese and shredding it at home because it melts more smoothly than packaged shredded cheese. Gruyere is another delicious option if you prefer a stronger, nuttier cheese flavor.

That’s it! Just four simple ingredients for a delicious cheesy potato appetizer.

What’s the best cheese to use?

For this recipe, my first choice is Swiss cheese.

It has a wonderful nutty flavor that’s slightly sweet, making it the perfect match for caramelized onions.

Swiss cheese also melts beautifully, creating a creamy topping that coats the potatoes without overpowering their natural flavor.

I recommend using traditional Swiss cheese from the deli or cheese section at the grocery store.

You can purchase it in a block and shred it yourself, or use thin slices cut into smaller pieces.

For the most even coverage, I prefer freshly shredded cheese.

Gruyere is another excellent option!

Gruyere is a type of Swiss cheese that’s generally aged longer and has a richer, nuttier flavor.

It’s especially delicious with caramelized onions, which is why it’s commonly used in French onion-inspired dishes.

If you want a slightly stronger cheese flavor, Gruyere is a great choice.

You can also combine half Swiss and half Gruyere cheese for a delicious combination of mild and rich flavors.

I don’t recommend using a very soft cheese like fresh mozzarella for this particular recipe. It contains more moisture and won’t give you quite the same savory, golden topping.

What are the best potatoes for potato bites?

I love using baby gold potatoes for this recipe!

They’re naturally creamy, slightly buttery, and easy to find at most grocery stores.

Their small size also makes them perfect for creating appetizer-sized rounds.

When sliced into approximately ½-inch pieces, baby gold potatoes create little bases that are sturdy enough to hold the caramelized onions and melted cheese.

Yukon Gold potatoes are another great option.

They have a similar flavor and texture, although you may need to choose smaller potatoes or cut the rounds into smaller pieces.

Red potatoes will also work.

They have a slightly firmer texture and thin skins, which means they’ll hold together nicely during baking.

You can leave the skins on for all of these potato varieties.

I actually recommend keeping the skins on because they help the rounds maintain their shape, and they add a little texture around the edges.

Russet potatoes aren’t my first choice for this recipe.

Their higher starch content makes them fluffy when cooked, but they can break apart more easily when sliced and handled.

For the best results, stick with baby gold, small Yukon Gold, or red potatoes.

Instructions

I’ve included step-by-step instructions below to make this recipe super easy to follow at home. For the full detailed recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.

You’ll need a large skillet, a pot for partially cooking the potatoes, and a rimmed baking sheet.

I recommend lining the baking sheet with parchment paper to make cleanup easier.

Step 1. Prepare the onions

Start by peeling one large yellow onion.

Cut the onion in half, then slice each half into thin strips, approximately ⅛-inch thick.

Try to keep the slices relatively even so they’ll cook at the same rate.

Place a large skillet on the stove over medium-low heat.

Add 2 tablespoons of unsalted butter.

Once the butter has melted, add the sliced onions to the skillet.

Stir to coat the onions in the melted butter, then spread them into an even layer.

Step 2. Caramelize the onions

Cook the onions over medium-low heat for approximately 30-40 minutes, stirring every few minutes.

At first, the onions will soften and release moisture.

After approximately 10-15 minutes, they’ll begin turning translucent and developing a light golden color.

Continue cooking, stirring occasionally, until the onions become a rich golden brown.

I recommend keeping the heat relatively low during this process.

You want the onions to soften and caramelize slowly, rather than turning dark and crispy on the outside.

If they begin browning too quickly, reduce the heat.

The finished onions should be soft, sweet, and golden, with a rich savory flavor.

Remove the skillet from the heat and set the onions aside while you finish preparing the potatoes.

Step 3. Prepare the potatoes

While the onions are cooking, wash the baby gold potatoes thoroughly under cold running water.

Use a sharp knife to slice the potatoes into approximately ½-inch thick rounds.

I recommend choosing potatoes that are similar in size so the finished bites will look relatively uniform.

Place the sliced potatoes in a large pot and cover them with cold water.

Bring the water to a boil over medium-high heat.

Reduce to a steady simmer and cook for approximately 5-7 minutes.

You want the potatoes to begin softening, but they should still be firm enough to hold their shape.

A fork should slide partway into the potato rounds with a little resistance.

Don’t cook them until they’re falling apart!

The potatoes will finish cooking in the oven, so they only need a little head start.

Drain the potatoes carefully in a colander.

Allow them to sit for a few minutes so any extra moisture can evaporate.

Step 4. Season the potatoes with butter

Preheat the oven to 425°F.

Line a large rimmed baking sheet with parchment paper.

Melt the remaining 1 tablespoon of unsalted butter.

Place the partially cooked potato rounds in a large mixing bowl.

Pour the melted butter over the potatoes and gently toss until they’re evenly coated.

Be careful not to break the potatoes while mixing.

Arrange the rounds on the prepared baking sheet in a single layer.

Leave a little space between each piece so the heat can circulate around the potatoes.

This helps the edges become lightly golden instead of steaming.

Step 5. Bake the potato rounds

Place the baking sheet in the preheated 425°F oven.

Bake for approximately 15-18 minutes, or until the potatoes are beginning to turn golden around the edges.

The bottoms should develop a little color, while the centers should be nearly tender.

If some of the potato rounds are much smaller than others, check them a little earlier.

You don’t want the potatoes to become too soft before adding the toppings.

Once they’re lightly golden, carefully remove the baking sheet from the oven.

Leave the oven on, because the potato bites will go back in for a few more minutes!

Step 6. Add the caramelized onions

Spoon a small amount of the caramelized onions onto each potato round.

I recommend using approximately 1 teaspoon of onions per bite, depending on the size of the potatoes.

Gently spread the onions over the top, keeping them near the center.

The sweet, buttery onions add so much flavor to these little potato bites!

Try to divide the onions evenly so every piece gets plenty of that delicious topping.

Step 7. Add the Swiss cheese

Sprinkle freshly shredded Swiss cheese over the caramelized onions.

Use approximately 1-2 teaspoons of cheese per potato round, depending on the size.

I like making a little mound of cheese over each bite.

As it melts, the cheese will cover the onions and spread slightly over the edges of the potatoes.

If you’re using thin slices of Swiss cheese instead of shredded cheese, cut each slice into smaller squares and place one over each potato.

Make sure the cheese doesn’t extend too far beyond the edges, or it may melt onto the baking sheet.

Step 8. Finish baking the potato bites

Return the baking sheet to the oven.

Bake for another 5-7 minutes, or until the Swiss cheese is completely melted and beginning to bubble.

The potatoes should now be tender in the center, with lightly golden edges.

If you want the cheese to develop a little extra color, you can turn the oven broiler on for the final 1-2 minutes.

Keep a close eye on the bites during this step!

The cheese can brown quickly under the broiler.

Remove the baking sheet from the oven once the cheese is melted and lightly golden.

Step 9. Garnish and serve

Allow the potato bites to rest on the baking sheet for approximately 3-5 minutes.

This gives the melted cheese a little time to settle and makes the bites easier to transfer without losing the toppings.

Use a thin spatula to carefully lift each potato round from the baking sheet.

Arrange the bites on a large serving platter.

Serve them warm, while the Swiss cheese is still soft and melted.

I love serving these as a party appetizer, but they’re also delicious alongside steak or roasted chicken for dinner.

They’re buttery, cheesy, and full of wonderful onion flavor!

Recipe tips

This recipe is really easy to make, but I’ve included a few tips to help you get the best Swiss Onion Potato Bites every time.

Use small potatoes. Baby gold potatoes are perfect for this recipe because they create appetizer-sized rounds. Larger potatoes will still work, but the finished pieces may be more difficult to pick up and eat.

Slice the potatoes evenly. I recommend approximately ½-inch thick rounds. If some slices are much thinner than others, they may become overly soft or brown before the thicker pieces are tender.

Partially cook the potatoes first. This is one of my favorite tips for making oven-baked potato appetizers. Giving the potatoes a few minutes in boiling water helps them become tender in the oven without needing a long baking time.

Drain the potatoes thoroughly. Extra water can prevent the potatoes from becoming golden around the edges. Let them drain for a few minutes before tossing them with melted butter.

Don’t rush the caramelized onions. Cooking onions slowly allows them to develop a naturally sweet flavor. If the heat is too high, they may burn before becoming fully softened.

Use freshly shredded Swiss cheese. Cheese shredded from a block melts more smoothly than packaged shredded cheese. It also gives the bites a wonderful creamy texture.

Don’t overcrowd the baking sheet. Arrange the potato rounds in a single layer with a little space between them. If they’re too close together, they’ll steam instead of developing golden edges.

Add the toppings near the end. The potatoes need more cooking time than the cheese. Waiting to add the onions and Swiss until the potatoes are almost finished prevents the cheese from overcooking.

Let the bites rest before serving. Just a few minutes on the baking sheet helps the melted cheese settle, making the potato bites easier to transfer to a platter.

How to caramelize onions for the best flavor

The caramelized onions are one of the most important parts of this recipe!

They’re what give these little potato bites their rich, sweet, and savory flavor.

And while caramelizing onions does take a little time, it’s actually really easy.

You only need onions, butter, a skillet, and a little patience.

Start by slicing the onions into thin, even pieces.

I recommend using yellow onions because they have a wonderful flavor that becomes sweeter as they cook.

Melt butter in a large skillet over medium-low heat, then add the onions.

As the onions cook, they’ll begin to soften and release moisture.

After approximately 10-15 minutes, they’ll become translucent and start developing a golden color.

Continue cooking, stirring every few minutes.

Over the next 15-25 minutes, the onions will slowly become darker, softer, and sweeter.

You want them to reach a rich golden brown color without burning.

If the onions begin sticking to the skillet, reduce the heat and stir more frequently.

For this recipe, I recommend allowing the onions to become fully caramelized before adding them to the potatoes.

Their sweet flavor pairs perfectly with the slightly nutty Swiss cheese.

And since the recipe only has four ingredients, taking the time to develop the flavor of the onions really makes a difference!

Can you make caramelized onions ahead of time?

Yes! This is one of my favorite ways to make this recipe easier when preparing food for a party.

You can caramelize the onions up to 4 days in advance.

Allow them to cool, then transfer them to an airtight container and refrigerate promptly.

When you’re ready to make the potato bites, gently warm the onions in a skillet or microwave.

They don’t need to be piping hot before adding them to the potatoes, since everything will finish cooking together in the oven.

This simple make-ahead step can save approximately 30-40 minutes on the day you’re serving the appetizers.

How to make the potatoes crispy

If you love potatoes with golden, slightly crispy edges, there are a few easy things you can do to get the best texture.

First, make sure the potatoes are sliced evenly.

Thicker potato rounds will have a softer center, while thinner slices tend to become crispier.

I recommend ½-inch rounds because they give you a nice balance of tender potatoes and lightly golden edges.

Next, partially cook the potatoes before roasting.

This may seem like an extra step, but it helps the inside become tender without having to leave the potatoes in the oven for too long.

After boiling, drain them thoroughly.

Moisture is one of the biggest reasons potatoes don’t brown properly in the oven.

Allowing the potatoes to sit in a colander for a few minutes helps remove some of that extra water.

Then toss them with melted butter.

The butter adds wonderful flavor and helps the potatoes develop a lightly golden exterior.

Finally, bake the potatoes in a single layer at 425°F.

The high oven temperature helps the edges brown while the centers finish cooking.

If you want slightly crispier potatoes, allow them to roast for another 2-3 minutes before adding the onions and cheese.

Just keep in mind that these are meant to be tender potato bites with golden edges, rather than crunchy potato chips.

The combination of creamy potatoes, caramelized onions, and melted Swiss is what makes them so delicious!

Recipe variations

One of my favorite things about this recipe is how easy it is to change the flavors.

The original version only needs four ingredients, but you can add a few extras if you want to make something different.

Here are a few delicious variations to try!

French onion potato bites

If you love French onion soup, you’ll definitely want to try this variation!

Replace the regular Swiss cheese with freshly shredded Gruyere.

Gruyere has a stronger, nuttier flavor that pairs wonderfully with caramelized onions.

You can also add a small pinch of dried thyme to the onions while they’re cooking.

The combination of golden potatoes, sweet onions, Gruyere, and thyme gives these little bites a delicious French onion-inspired flavor.

Bacon Swiss potato bites

If you love bacon, this variation is for you!

Cook 4 slices of bacon until crispy, then crumble them into small pieces.

Prepare the potato bites according to the recipe instructions.

After adding the caramelized onions, sprinkle a little bacon over each potato round.

Top with Swiss cheese and finish baking.

The smoky, salty bacon is a delicious addition to the sweet onions and melted cheese.

I recommend saving a little extra bacon to sprinkle over the bites just before serving.

Garlic butter Swiss potato bites

Garlic and potatoes are always a delicious combination!

Melt the tablespoon of butter used for coating the potatoes, then stir in 2 cloves of freshly minced garlic.

Toss the partially cooked potatoes with the garlic butter before arranging them on the baking sheet.

Continue preparing the recipe as directed.

The garlic adds a wonderful savory flavor that pairs perfectly with the caramelized onions and Swiss cheese.

Cheddar onion potato bites

If you prefer cheddar cheese, you can easily use it instead of Swiss.

I recommend sharp cheddar because its rich flavor pairs perfectly with the sweet onions.

Use the same amount of freshly shredded cheese and follow the remaining instructions.

This version has a slightly stronger cheese flavor and is especially delicious served with ranch dressing for dipping.

Mushroom Swiss potato bites

If you love mushrooms and Swiss cheese, this variation is definitely worth trying!

Finely chop 4 ounces of baby bella mushrooms.

Add them to the skillet during the final 8-10 minutes of cooking the onions.

Continue cooking until the mushrooms are tender and most of their moisture has evaporated.

Spoon the mushroom and onion mixture over the potato rounds, then top with Swiss cheese.

The combination of earthy mushrooms, sweet onions, and melted cheese is so flavorful!

Frequently asked questions

Can you make these potato bites without boiling the potatoes first?

Yes! You can make these potato bites without partially cooking the potatoes, but you’ll need to increase the baking time.

Slice the raw potatoes into approximately ¼-inch thick rounds instead of ½-inch pieces.

Toss them with melted butter and arrange them on a parchment-lined baking sheet.

Bake at 425°F for approximately 20-25 minutes, flipping halfway through, until the potatoes are nearly tender.

Add the caramelized onions and Swiss cheese, then return them to the oven for another 5-7 minutes.

The exact cooking time will depend on the thickness of the potatoes.

I prefer partially cooking the potatoes because it creates a creamier center and makes the baking time more predictable.

Can you use frozen potatoes?

Yes, although I recommend using fresh potatoes for the best presentation.

Frozen diced potatoes or hash browns won’t create the same neat, round appetizer bites.

If you want to use frozen potatoes, look for frozen potato rounds or thick potato slices.

Cook them according to the package directions until they’re nearly tender, then top them with caramelized onions and Swiss cheese.

Return them to the oven until the cheese is melted.

The texture will be a little different from the homemade version, but the flavors will still be delicious.

Can you use sliced Swiss cheese instead of shredded?

Absolutely!

If you have sliced Swiss cheese in the refrigerator, there’s no need to purchase a block.

Simply cut the cheese slices into small squares that are slightly smaller than the potato rounds.

Place one piece of cheese over each potato after adding the caramelized onions.

Bake until the cheese melts and begins to bubble.

I prefer shredded cheese because it’s easier to divide evenly between the bites, but sliced cheese works just fine.

Can you make these potato bites ahead of time?

Yes! You can prepare most of the recipe ahead of time.

Caramelize the onions up to 4 days in advance and refrigerate them in an airtight container.

You can also slice and partially cook the potatoes the day before serving.

Allow the potatoes to cool, then refrigerate them in a sealed container.

When you’re ready to make the bites, toss the potatoes with melted butter and arrange them on the baking sheet.

Bake until nearly tender and golden, then add the onions and cheese.

You may need a few extra minutes in the oven if the potatoes are starting cold.

For the best texture, I recommend adding the cheese and finishing the bites shortly before serving.

Can you make these potato bites in an air fryer?

Yes! An air fryer is a great option if you’re making a smaller batch.

Preheat the air fryer to 400°F.

Arrange the partially cooked, butter-coated potato rounds in a single layer in the air fryer basket.

Cook for approximately 8-10 minutes, or until the potatoes are lightly golden and nearly tender.

Carefully add the caramelized onions and Swiss cheese.

Return the potatoes to the air fryer for another 2-3 minutes, until the cheese melts.

The exact cooking time will depend on your air fryer.

I recommend checking the bites frequently once the cheese is added, since it can melt and brown quickly.

Can you double the recipe?

Yes! These potato bites are perfect for doubling when you’re feeding a crowd.

Use 3 pounds of baby gold potatoes, 2 large yellow onions, 6 tablespoons of butter, and 3 cups of shredded Swiss cheese.

I recommend dividing the potatoes between two large baking sheets.

You want the potato rounds arranged in a single layer with a little space between them.

If baking both sheets at the same time, rotate them halfway through cooking for more even browning.

You may need to add a few extra minutes to the baking time.

Are these potato bites gluten free?

The four main ingredients in this recipe are naturally gluten free.

However, if you’re preparing the bites for someone who needs to avoid gluten, I recommend checking the labels on the cheese and butter to make sure there aren’t any unexpected gluten-containing additives.

Also make sure your preparation surfaces and utensils are free from cross-contact with gluten-containing foods.

You don’t need flour, breadcrumbs, or any other gluten-containing ingredients to make these delicious potato appetizers!

What to serve with Swiss onion potato bites

These Oven Baked Swiss Onion Potato Bites are delicious served as an appetizer or side dish.

Since they’re rich, buttery, and cheesy, I love pairing them with a simple main course or a fresh salad.

Grilled steak is one of my favorite meals to serve with these potato bites. The caramelized onions and Swiss cheese pair perfectly with the savory flavor of beef.

Roasted chicken is another delicious option. A simple garlic herb roasted chicken tastes wonderful alongside the cheesy potatoes.

Pork chops are also a great pairing. The sweet caramelized onions add a delicious flavor that complements pork.

Burgers are perfect if you’re serving these bites as an alternative to French fries. I especially love them with a classic cheeseburger or patty melt.

A green salad is a great option when serving the potato bites as part of a lighter meal. Crisp lettuce, tomatoes, cucumbers, and a tangy vinaigrette balance the richness of the cheese.

Roasted vegetables are another delicious side. Broccoli, asparagus, green beans, or Brussels sprouts all pair well with potatoes and Swiss cheese.

If you’re serving these at a party, you can also put out a few dipping sauces.

Ranch dressing, sour cream, or a creamy garlic dip are all delicious options.

For a holiday appetizer spread, I like the idea of serving these alongside stuffed mushrooms, cheese bites, and other easy finger foods.

They’re simple to pick up and full of flavor, making them a great addition to almost any gathering.

How to keep potato bites warm for a party

If you’re making these potato bites for a gathering, you’ll want to keep them warm until everyone is ready to eat.

I recommend preparing the caramelized onions ahead of time, then baking the potatoes shortly before serving.

Once the cheese is melted and the potatoes are tender, remove the baking sheet from the oven.

If you’re not serving them immediately, you can keep the bites in a low oven, around 200°F, for a short period, provided the food stays at 140°F or above.

Arrange them in a single layer on the baking sheet so they don’t become crowded.

I don’t recommend covering them tightly with foil while keeping them warm.

Trapped steam can soften the golden edges of the potatoes and make the cheese topping a little wet.

For the best flavor and texture, serve these bites within approximately 20-30 minutes of finishing them.

If you’re preparing several batches, you can bake the potato rounds ahead of time and add the onions and Swiss cheese just before serving.

This helps keep the finished bites warm, cheesy, and delicious!

How to store and reheat leftovers

One of the best things about making a big batch of potato bites is having leftovers for another meal!

These cheesy potatoes are delicious reheated, especially when warmed in the oven or air fryer.

How to store them

Allow the potato bites to cool slightly, then transfer them to shallow, airtight containers.

Refrigerate within 2 hours of cooking.

Leftover Swiss Onion Potato Bites will stay good in the refrigerator for 3-4 days when stored properly at 40°F or below.

I recommend arranging them in a single layer if possible.

If you need to stack them, place a sheet of parchment paper between the layers to help keep the toppings intact.

How to reheat them

My favorite way to reheat these potato bites is in the oven.

Preheat the oven to 375°F.

Arrange the leftover bites on a parchment-lined baking sheet.

Bake for approximately 8-12 minutes, or until the potatoes are hot throughout and the cheese is melted again.

Reheat leftovers thoroughly to 165°F.

You can also use an air fryer.

Preheat the air fryer to 350°F and arrange the bites in a single layer.

Heat for approximately 4-6 minutes, checking frequently, until hot throughout.

The air fryer is a great option if you want to bring back some of the lightly crispy texture around the edges.

I don’t recommend reheating these bites in the microwave if you want crispy edges, since the potatoes will become softer.

However, the microwave will work if you’re just reheating a few pieces for a quick snack.

Can you freeze Swiss onion potato bites?

Yes, you can freeze these potato bites, although the texture may change slightly after thawing.

Cooked potatoes sometimes become a little softer or grainier after freezing, and the cheese may lose some of its smooth texture.

For the best results, I recommend freezing the baked potato rounds before adding the onion and cheese toppings.

Allow the potatoes to cool, then arrange them in a single layer on a parchment-lined baking sheet.

Freeze until firm, then transfer them to a freezer-safe container or bag.

Freeze for up to 2 months for the best quality.

When you’re ready to serve, arrange the frozen potato rounds on a baking sheet and heat them in a 400°F oven until hot and nearly crispy.

Add the caramelized onions and Swiss cheese, then return them to the oven until the cheese melts.

This is a convenient way to prepare part of the recipe ahead of time!

Cheesy smashed potatoes are another great option. Small potatoes are boiled until tender, smashed flat, then roasted with butter and cheese until golden and crispy.

Loaded potato skins are perfect for game day parties. Crispy potato skins filled with melted cheddar cheese, bacon, and green onions make a delicious handheld appetizer.

French onion crescent rolls combine sweet caramelized onions and melted cheese wrapped inside buttery crescent roll dough.
