These Oven Baked 4-Ingredients Mini Potato Gratin Stacks are the perfect combination of creamy, cheesy potatoes and crispy, golden brown edges! Made with just four simple ingredients, thinly sliced potatoes are layered in a muffin tin with heavy cream, butter, and Parmesan cheese, then baked until tender and delicious. They’re an easy, impressive side dish for holiday dinners, family gatherings, or anytime you’re craving cheesy potatoes!

If you love traditional potatoes au gratin, you’re going to love this fun, individual-sized version! You get all of the creamy goodness of classic potato gratin, but with even more crispy edges and a beautiful presentation.

I’ve always loved recipes that turn a handful of everyday ingredients into something that looks like it took hours to prepare. And these little potato stacks are exactly that!

The best part? You don’t need a special baking dish, a complicated cheese sauce, or a long list of ingredients. Just grab a few potatoes, some cream, butter, and Parmesan cheese, and you’re ready to make one seriously delicious side dish.

Instead of arranging the potatoes in a large casserole dish, you’ll layer them in a standard muffin pan. This creates individual servings with tender centers, cheesy layers, and golden brown edges that get slightly crispy in the oven.

I especially love serving these mini potato gratins for holidays. They’re easy to portion, look beautiful on a dinner plate, and pair with everything from roasted chicken to a juicy steak.

And since they’re made with only four ingredients, they’re also easy enough to prepare for a regular weeknight dinner.

Why you’ll love these potato gratin stacks

There’s a lot to love about this simple potato recipe! From the creamy centers to the crispy edges, every little stack is packed with delicious flavor.

Here are a few reasons I love making them!

Only 4 ingredients! You don’t need flour, eggs, breadcrumbs, or an assortment of seasonings to make these potatoes taste amazing. The combination of salted butter, Parmesan cheese, and heavy cream adds plenty of rich, savory flavor.

Perfectly portioned servings. Baking the potatoes in a muffin tin makes it easy to serve individual stacks. This is especially helpful when you’re preparing dinner for a group or planning a holiday meal.

Creamy centers and crispy edges. The potatoes absorb the cream as they bake, creating tender layers inside each stack. Meanwhile, the edges turn golden brown, giving every bite a little bit of crispiness.

Easy to prepare ahead of time. You can bake these mini gratins in advance and reheat them in the oven before serving. This makes them an excellent choice when you’re preparing several dishes for a special occasion.

No complicated cooking techniques. If you can slice potatoes, toss them with cream and cheese, and arrange them in a muffin pan, you can make this recipe!

They’re simple enough for an everyday dinner but look impressive enough to serve at Thanksgiving, Christmas, Easter, or a dinner party.

Ingredients

You only need four ingredients to make these creamy, cheesy mini potato gratin stacks!

Here I’ll explain the best ingredients to use, what each one adds to the recipe, and a few helpful tips for getting the best results.

For the exact ingredient measurements, see the recipe card at the bottom of this post.

1. Yukon Gold potatoes

You’ll need 2 pounds of Yukon Gold potatoes to make 12 individual potato gratin stacks.

I recommend Yukon Gold potatoes because they have a naturally buttery flavor and a creamy texture that works perfectly in this recipe.

They contain enough starch to help the potato slices hold together, but they don’t become overly dry after baking.

Their thin skins are also tender enough to leave on, which saves time during preparation.

If you prefer a smoother appearance, you can peel the potatoes before slicing them.

You can also make this recipe with russet potatoes. They’re higher in starch and will give you a softer, more delicate center. Just keep in mind that russet potatoes are usually larger, so you may need to trim the slices to fit inside the muffin cups.

For the best presentation, I recommend choosing medium-sized potatoes that are close in diameter to the muffin cups.

2. Heavy cream

You’ll need ¾ cup heavy cream for this recipe.

Heavy cream is what gives these potato stacks their rich, creamy texture. As the potatoes bake, the cream heats up and works its way between the thin slices.

The result is tender potatoes with a deliciously creamy center.

I recommend using full-fat heavy whipping cream for the best results. The higher fat content helps create a rich sauce without requiring flour or another thickening ingredient.

You can substitute half-and-half if you’d like, but the potatoes won’t be quite as creamy.

I don’t recommend using skim milk. It’s much thinner than heavy cream and won’t give the potatoes the same texture.

3. Parmesan cheese

You’ll need 1 cup finely grated Parmesan cheese, divided between the potato layers and the topping.

Parmesan adds a wonderful savory flavor that balances the richness of the cream and butter.

It also helps the exposed potato edges turn golden brown during baking.

I recommend freshly grating Parmesan cheese from a block. Freshly grated cheese blends more evenly with the cream and has a better flavor than many packaged varieties.

Finely grated Parmesan works particularly well because it can settle between the potato slices instead of forming thick clumps of cheese.

Since Parmesan is naturally salty, it also helps season the potatoes without needing to add another ingredient.

If you’d like a stronger cheese flavor, you can use aged Parmesan.

4. Salted butter

You’ll need 2 tablespoons salted butter, melted and divided.

The butter serves two purposes in this recipe.

First, you’ll use half of it to coat the muffin cups. This helps prevent the potatoes from sticking and encourages the edges to become golden brown.

The remaining butter gets tossed with the sliced potatoes, cream, and Parmesan cheese.

I recommend salted butter because it adds extra seasoning to the potatoes without increasing the ingredient count.

If you only have unsalted butter, you can use it, but the finished potatoes may need additional seasoning.

Instructions

Making these Oven Baked Mini Potato Gratin Stacks is actually quite easy!

The most important part is slicing the potatoes evenly. Once they’re sliced, everything comes together in just a few minutes.

Follow these simple steps to make perfectly tender, creamy potato stacks with deliciously crispy edges.

Step 1. Prepare the muffin pan

Preheat the oven to 375°F (190°C).

Grab a standard 12-cup muffin pan and place it on a large, rimmed baking sheet.

The baking sheet will catch any cream that bubbles over the edges of the muffin cups while the potatoes are baking.

Melt the butter in a small microwave-safe bowl or saucepan.

Use approximately 1 tablespoon of the melted butter to generously coat the bottom and sides of each muffin cup.

Make sure you get the butter around the edges, since this is where the cheese and cream will brown as the potatoes bake.

I recommend using a nonstick muffin pan for this recipe. Even with butter, the cheese can stick to the edges of an uncoated pan.

Step 2. Slice the potatoes

Wash and scrub the potatoes to remove any dirt.

You can peel them if you’d like, but I usually recommend leaving the skins on Yukon Gold potatoes. They’re thin, tender, and add a little extra texture to the finished stacks.

Using a sharp knife or mandoline slicer, cut the potatoes into thin rounds, approximately ⅛ inch thick.

Try to keep all of the slices as close to the same thickness as possible.

This will help the potato layers cook evenly, so you don’t end up with some slices that are tender and others that are still firm.

A mandoline slicer makes this step especially easy. It produces uniform slices in much less time than slicing the potatoes by hand.

If you’re using a mandoline, be sure to use the safety guard to protect your fingers.

Important tip: Don’t rinse the potatoes after slicing them! The natural starch on the surface of the slices helps the cream thicken slightly and encourages the layers to hold together.

Step 3. Combine the potatoes with the cream and cheese

Place the sliced potatoes in a large mixing bowl.

Pour the heavy cream over the potatoes, then add the remaining tablespoon of melted butter.

Sprinkle in ¾ cup of the grated Parmesan cheese, reserving the remaining ¼ cup for the topping.

Use your hands or a large spoon to gently toss everything together.

You want each potato slice lightly coated in the cream and cheese mixture.

If the potato slices are sticking together, separate them as you toss so the cream can reach the individual layers.

This is what gives the potatoes their creamy texture throughout the stacks, instead of just on the top.

Don’t worry if there is a little cream left in the bottom of the bowl. You’ll add it to the muffin cups after arranging the potatoes.

Step 4. Assemble the potato stacks

Begin layering the potato slices in the prepared muffin pan.

Place a few slices in the bottom of each muffin cup, then continue stacking until you’ve used all of the potatoes.

I recommend arranging the potatoes from largest to smallest, when possible.

Place the larger rounds toward the bottom of the muffin cups and the smaller ones toward the top.

This helps create stacks that fit neatly inside the pan and hold their shape when removed.

Don’t worry if the slices aren’t all perfectly round or exactly the same size. As they bake, the potatoes will soften and settle into the muffin cups.

Fill each cup almost to the top, pressing the layers down gently as you go.

If there is any cream mixture remaining in the bowl, spoon it evenly over the stacks.

You don’t want the muffin cups overflowing with liquid, but a little cream in the bottom of each cup will help keep the potatoes tender.

Step 5. Bake the potatoes

Cover the muffin pan loosely with aluminum foil.

Place the baking sheet with the muffin pan in the preheated oven and bake for 25 minutes.

Covering the potatoes during the first part of baking helps trap steam, allowing the thin slices to soften without the tops browning too quickly.

After 25 minutes, carefully remove the foil.

Sprinkle the remaining ¼ cup Parmesan cheese evenly over the tops of the potato stacks.

Return the uncovered muffin pan to the oven and bake for another 18-22 minutes.

The potatoes are ready when the tops are golden brown, the edges are lightly crispy, and a thin knife slides easily through the center of a stack.

If the potatoes are browning too quickly but still feel firm in the middle, loosely cover them with foil again and continue baking until tender.

Step 6. Allow the stacks to rest

Remove the muffin pan from the oven and allow the potato stacks to rest for 8-10 minutes.

This is one step you don’t want to skip!

When the potatoes first come out of the oven, the cream and cheese will still be bubbling around the edges.

Letting them rest gives the creamy layers a chance to settle and makes it easier to remove each stack without it falling apart.

Once they’ve rested, run a thin butter knife around the edge of each muffin cup.

Carefully lift the potato stacks out using a small offset spatula or spoon.

Transfer them to a serving platter or individual dinner plates.

Serve warm and enjoy the delicious combination of tender, creamy potatoes and crispy Parmesan edges!

Tips for making the best mini potato gratin stacks

I’ve included a few helpful tips below to make sure your potato gratin stacks turn out delicious every time!

Slice the potatoes evenly

This is probably the most important tip for this entire recipe.

When the potatoes are all the same thickness, they’ll cook at approximately the same rate.

If some slices are much thicker than others, the thinner slices may become very soft before the thicker pieces are fully cooked.

I recommend slicing the potatoes approximately ⅛ inch thick.

If you have a mandoline slicer, this is a great time to use it!

Don’t soak the sliced potatoes

When making crispy french fries, soaking potatoes can help remove excess starch.

But for these gratin stacks, you actually want to keep that starch!

The natural starch on the potatoes helps bind the creamy layers together as they bake.

Wash the potatoes before slicing them, then transfer the slices directly into the cream mixture.

Use freshly grated cheese

For the best flavor and texture, grate the Parmesan cheese yourself.

Some pre-grated varieties contain additives that can affect how evenly they combine with the cream.

Freshly grated Parmesan also has a richer flavor, which is especially helpful in a recipe with only four ingredients.

Don’t overfill the muffin cups

It’s tempting to pile the potato slices as high as possible, but I recommend stopping right around the rim of each muffin cup.

The potatoes will settle slightly during baking.

If they’re stacked too high, the top slices can slide off and the cream may bubble over the sides.

A little space at the top also gives the Parmesan room to brown.

Cover the potatoes during the first part of baking

The foil helps the potatoes cook through before the tops become too brown.

Without it, the top layers can dry out while the potatoes in the center are still firm.

Removing the foil for the final 18-22 minutes allows the tops and edges to develop their golden brown color.

It’s the combination of covered and uncovered baking that gives these mini gratins their tender centers and lightly crispy edges.

Let them cool before removing them

I know it’s tempting to pull these little potato stacks straight out of the pan as soon as they’re done baking.

But giving them a few minutes to rest makes a big difference.

As the cream cools slightly, the layers become easier to handle.

For the neatest presentation, wait at least 8 minutes before removing the potatoes from the muffin pan.

Frequently asked questions

What are potato gratin stacks?

Potato gratin stacks are an individual-sized version of traditional potatoes au gratin.

Classic potato gratin is usually made by layering thinly sliced potatoes in a baking dish with cream and cheese, then baking everything until the potatoes are tender and the top is golden brown.

For these mini gratins, you’ll use the same basic ingredients but arrange the potato slices vertically in individual muffin cups.

This creates little towers of creamy potatoes with more exposed edges, giving each serving a delicious combination of textures.

They’re also easier to portion than a large casserole.

What type of potatoes are best for gratin stacks?

I recommend Yukon Gold potatoes for their creamy texture and naturally buttery flavor.

They hold their shape nicely when sliced and baked, which makes them a great choice for individual potato stacks.

Russet potatoes are another option, but they contain more starch and tend to become softer during cooking.

Red potatoes can also work, although their waxy texture creates a firmer finished stack.

For the creamiest results, Yukon Gold potatoes are my first choice.

Can I make these without a mandoline?

Absolutely!

A mandoline makes slicing the potatoes faster and more consistent, but you can make this recipe with a sharp kitchen knife.

The key is cutting the slices as evenly as possible.

Aim for approximately ⅛ inch thickness and take your time.

If you’re slicing by hand, choosing potatoes that are similar in size will make the process easier.

Can I use a different type of cheese?

Yes! While Parmesan is delicious in this four-ingredient version, you can substitute another cheese if you’d like.

Gruyere is an excellent choice because it has a rich, slightly nutty flavor and melts beautifully.

Sharp cheddar will give the potatoes a stronger cheese flavor, while Swiss cheese makes a milder, creamy gratin.

Just remember that Parmesan is naturally saltier than many other cheeses.

If you’re substituting a milder cheese, you may want to season the potatoes with a little additional salt.

Why are my potato stacks falling apart?

There are a few reasons potato gratin stacks might not hold together.

The first is that the potato slices may be too thick. Thinner slices soften and settle together more easily during baking.

Another possibility is that the stacks haven’t cooked long enough.

The potatoes should be completely tender before removing them from the oven.

And finally, make sure you let the potatoes rest before lifting them out of the muffin pan.

The cream and cheese need a few minutes to settle around the potato layers.

If you try to remove the stacks immediately, they’re more likely to separate.

How do I know when they’re fully cooked?

The easiest way to check is with a thin knife or fork.

Insert it into the center of one potato stack.

If it slides through the layers without resistance, the potatoes are ready.

You should also see golden brown tops and lightly browned edges.

Depending on the thickness of your potato slices and the size of your muffin pan, you may need a few additional minutes of baking time.

Can I make them in a mini muffin pan?

You can, but you’ll need to make a few adjustments.

A mini muffin pan requires smaller potato slices, so choose small potatoes or trim larger rounds to fit.

You’ll also need to reduce the baking time, since the smaller stacks will cook faster.

I recommend checking them after approximately 20 minutes, then continuing until they’re tender and lightly golden.

For the easiest preparation and most consistent results, I prefer using a standard 12-cup muffin pan.

Recipe variations

One of my favorite things about this potato recipe is how easy it is to customize!

The original recipe is made with only four ingredients, but you can add a few extras when you want to change up the flavor.

Here are some delicious variations to try.

Garlic Parmesan potato stacks

If you love garlic potatoes, add 2-3 cloves of freshly minced garlic to the cream mixture.

Toss the garlic with the potatoes, cream, butter, and Parmesan before arranging everything in the muffin pan.

The garlic will soften as the potatoes bake, adding a wonderful savory flavor.

You can also add ½ teaspoon garlic powder for a quicker option.

Cheddar potato gratin stacks

Replace the Parmesan cheese with freshly shredded sharp cheddar.

Cheddar gives the potatoes a rich, familiar cheese flavor and a slightly softer topping.

I recommend using sharp cheddar instead of mild cheddar because its stronger flavor stands out against the cream and potatoes.

Add a little salt to taste if needed, since cheddar is generally less salty than Parmesan.

Herb potato stacks

Add 1 teaspoon fresh thyme leaves or finely chopped rosemary to the cream mixture.

Both herbs pair beautifully with potatoes and butter.

I especially love rosemary potatoes alongside roasted chicken or steak.

You can also sprinkle a little fresh parsley over the baked stacks just before serving.

Bacon and cheese potato stacks

For a heartier version, add ½ cup cooked, crumbled bacon between the potato layers.

The bacon adds a smoky, salty flavor that pairs perfectly with the creamy potatoes.

This variation is delicious served with grilled chicken, burgers, or a simple salad.

Just make sure the bacon is fully cooked before adding it to the potatoes.

Extra cheesy potato stacks

If you’re a cheese lover, try using a combination of Parmesan and Gruyere.

Use ½ cup grated Parmesan and ½ cup shredded Gruyere in place of the original cup of Parmesan.

The Parmesan adds a salty, savory flavor, while the Gruyere melts into the creamy potato layers.

You’ll get a rich, cheesy center and a beautiful golden brown topping.

What to serve with potato gratin stacks

These mini potato gratin stacks are incredibly versatile!

They’re elegant enough for special occasions but easy enough to serve with a simple family dinner.

I love pairing them with roasted meats, grilled chicken, and vegetable dishes.

Here are some of my favorite ways to serve them.

With steak: Creamy potatoes and a juicy steak are always a delicious combination. Serve two potato stacks with grilled ribeye, filet mignon, or sirloin, along with roasted asparagus or green beans.

With roasted chicken: These cheesy potatoes pair perfectly with oven-roasted chicken thighs or a whole roasted chicken. Add a simple green salad for a complete meal.

For Thanksgiving: Serve the mini gratins alongside roasted turkey, green bean casserole, cranberry sauce, and your favorite holiday vegetables. Their individual portions make them especially convenient for a large dinner.

For Christmas dinner: Potato gratin stacks are wonderful served with prime rib, roast beef, or baked ham. The golden brown tops look beautiful on a holiday table.

With salmon: Pair the potatoes with baked salmon and steamed broccoli for a dinner that’s both comforting and easy to prepare.

For brunch: These little potato stacks also work as a brunch side dish. Serve them with scrambled eggs, breakfast sausage, or a vegetable frittata.

Since the potatoes are already rich and creamy, I recommend pairing them with something fresh or lightly seasoned to balance the meal.

A simple green salad, roasted Brussels sprouts, or sautéed green beans are all delicious options.

How to make them ahead of time

If you’re planning a holiday dinner or hosting a gathering, you’ll be happy to know that these potato gratin stacks can be prepared ahead of time!

I recommend baking them completely, allowing them to cool, then storing them in the refrigerator until you’re ready to serve.

You can prepare them up to 2 days in advance for the best texture.

Once the potatoes have cooled, transfer them to an airtight container and refrigerate.

When you’re ready to serve, arrange the stacks on a baking sheet and reheat them in a preheated 350°F oven for approximately 12-15 minutes, or until heated all the way through.

If the tops are already nicely browned, you can loosely cover them with foil during reheating.

I don’t recommend assembling the raw potato stacks the night before and leaving them in the refrigerator without baking.

Raw sliced potatoes can discolor, and the cream mixture may not coat the layers as evenly after sitting for several hours.

For the easiest make-ahead option, bake the potatoes first and reheat them just before serving.

How to store and reheat leftovers

If you have leftover potato gratin stacks, don’t throw them away!

They reheat nicely and make a delicious side dish for lunch or dinner the next day.

Refrigerator storage

Allow the cooked potatoes to cool, then transfer them to an airtight container.

Store them in the refrigerator for up to 4 days.

Refrigerate leftovers within 2 hours of baking.

I recommend keeping the stacks in a single layer when possible so they don’t get crushed.

Reheating in the oven

For the best texture, I recommend reheating these mini potato gratins in the oven.

Preheat the oven to 350°F.

Place the potato stacks on a baking sheet and heat for 12-15 minutes, or until hot in the center.

If you want the edges to become a little crispier, increase the oven temperature to 400°F for the final 2-3 minutes.

Keep an eye on them so the cheese doesn’t burn.

Reheating in the air fryer

An air fryer is another great option for reheating these potatoes.

Preheat the air fryer to 325°F.

Arrange the stacks in a single layer and heat for approximately 5-7 minutes, checking that they’re hot all the way through.

The circulating hot air helps restore some of the crispiness around the edges.

Reheating in the microwave

If you’re short on time, you can also reheat the potatoes in the microwave.

Place one or two stacks on a microwave-safe plate and heat in 30-second intervals until hot.

The microwave will soften the crispy edges, but the potatoes will still taste delicious!

Can you freeze potato gratin stacks?

You can freeze them, but I don’t recommend it if you want to preserve the best texture.

Cream-based potato dishes can become watery or slightly grainy after freezing and thawing.

The potatoes may also become softer than they were when freshly baked.

Since these stacks can be refrigerated for several days, I recommend making them ahead and storing them in the fridge instead.

More tips for serving these potatoes at a party

These mini potato stacks are one of those side dishes that look especially nice when arranged together on a serving platter.

For a dinner party, I recommend making the stacks in a standard muffin pan so that each serving is approximately the same size.

This makes it easy for guests to help themselves.

If you’re serving them as part of a larger meal with several side dishes, one stack per person may be enough.

For a meal where potatoes are the main side dish, I recommend planning on two stacks per person.

This recipe makes 12 stacks, or approximately 6 generous side-dish servings.

If you’re cooking for a larger group, you can easily double the recipe and use two muffin pans.

Just be sure to arrange the pans on separate oven racks and rotate them halfway through baking for more even cooking.

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

I like to remove the potato gratins from the muffin pan before bringing them to the table. They’re easier to serve this way, and the beautifully browned edges are visible.

You can arrange them closely together on a platter to help keep them warm.

For the best flavor and texture, serve them shortly after baking or reheating.

The centers will still be creamy, the cheese will be warm, and the edges will have that delicious little crunch that makes these stacks so good!

Are these potato gratin stacks gluten free?

Yes! This four-ingredient potato gratin recipe is naturally gluten free when prepared with ingredients that don’t contain gluten or gluten-containing additives.

Potatoes, heavy cream, butter, and Parmesan cheese don’t normally contain gluten.

There’s no flour or breadcrumb coating needed to make the cream thicken.

The natural starch in the potatoes helps create the creamy consistency as they bake.

If you’re preparing these potatoes for someone who needs to avoid gluten, check the packaging of your ingredients and make sure there’s no cross-contact during preparation.

Can you make this recipe without heavy cream?

If you don’t have heavy cream available, you can make these potato stacks with half-and-half.

Use the same ¾ cup measurement.

The finished stacks will be a little lighter and the sauce may be thinner, but the potatoes should still bake until tender.

Whole milk is another option, although it won’t create the same creamy consistency.

If you’re using whole milk, I recommend reducing the quantity slightly so the potatoes don’t become too watery.

For the original four-ingredient recipe, heavy cream will give you the richest and most consistent results.

The secret to crispy edges and creamy centers

The combination of butter, heavy cream, and Parmesan cheese is what makes these little potato stacks so delicious.

As the potatoes bake, the cream softens the thin layers and creates a rich, tender center.

Meanwhile, the butter helps the outside edges brown against the hot muffin pan.

The Parmesan cheese adds flavor throughout the potatoes and forms a lightly crisp topping when exposed to the heat of the oven.

The size of the potato slices also makes a difference.

Very thick slices won’t soften as evenly, while extremely thin slices can become too delicate to handle.

Cutting them approximately ⅛ inch thick gives you a nice balance between tender layers and stacks that hold together.

You’ll also want to give the potatoes enough time in the oven.

If the tops are golden but the centers are still firm, continue baking them under a loose layer of foil.

The potatoes should be completely tender before you remove them from the oven.

Once they’re done, give them a few minutes to rest.

You’ll have beautiful little potato gratins with creamy centers, golden tops, and just the right amount of crispy cheese around the edges.

A simple potato side dish you’ll make again and again
