A warm, comforting side dish that tastes just like Grandma’s house smells on a Sunday afternoon.
💛 Welcome to My Cozy Kitchen!
Let me just start by saying—this dish brings back so many memories, I can almost hear the creak of the old wooden floorboards in my grandmother’s farmhouse and smell the pot roast she had bubbling away in the oven.
I was inspired to create this Slow Cooker Amish Green Bean Casserole on a rainy Thursday when I needed a little comfort food without turning on the oven. I remembered how my Aunt Millie used to make her famous green beans with bits of bacon, slow-simmered in a creamy broth with just a hint of sweetness. It was the kind of dish that didn’t look fancy, but you couldn’t stop eating it. So I set out to recreate that flavor—with a modern twist that makes it even easier for busy weeknights or big family gatherings. And you know what? I think Aunt Millie would be proud.

Frequently Asked Questions (FAQs) ❓
Can I make this ahead of time for a holiday or potluck?
Absolutely, and honestly—it’s even better the next day! You can assemble everything the night before (except the crispy fried onions for topping). Just cover your slow cooker insert and refrigerate overnight. When you’re ready, pop it into the slow cooker base and cook according to the recipe directions. If it’s cold from the fridge, you might need to add 30–45 minutes to the cooking time. Add the final layer of crispy onions right before serving for that satisfying crunch. It’s a lifesaver when you’re juggling multiple dishes during the holidays!
What’s the best way to keep this warm for serving at a buffet or family dinner?
This casserole is super forgiving, which makes it perfect for serving over several hours. Once it’s done cooking, just switch your slow cooker to the “keep warm” setting and leave the lid slightly ajar (this helps prevent it from getting too watery). If the sauce starts to thicken too much, just stir in a splash of milk or a spoonful of sour cream to loosen it up again. And don’t forget to wait until just before serving to sprinkle on the last handful of crispy onions so they stay nice and crunchy!
Can I make this vegetarian?
Yes, you can absolutely make a delicious meatless version! Simply leave out the bacon and consider adding 1/2 teaspoon of smoked paprika or a few dashes of liquid smoke to keep that savory depth of flavor. For extra texture, you could stir in sautéed mushrooms or even a handful of chopped walnuts for a fun twist. If you’re using a vegetarian cream of mushroom soup, just double-check the label to ensure it doesn’t contain chicken broth or gelatin—some brands sneak it in!
How do I keep the green beans from getting mushy in the slow cooker?
Great question—this is all about timing and type! If you’re using fresh green beans, they’ll hold up beautifully over the full 4–5 hours on LOW. Just trim and cut them into bite-sized pieces. If you use frozen green beans, be sure to thaw and pat them dry first to remove excess moisture. And for canned green beans, they’re already fully cooked, so you’ll want to stir them in during the last hour of cook time or they’ll turn to mush. Keep in mind, the longer they sit in the sauce, the softer they’ll get—still tasty, just not as firm.
Ingredients You’ll Need:
Here’s everything that goes into this beauty, with a few tips along the way!
- 2 lbs of fresh green beans, trimmed (you can use frozen in a pinch—just thaw and pat dry)
- 1 medium yellow onion, finely chopped
- 6 strips of thick-cut bacon, cooked crisp and crumbled (save a little for garnish!)
- 1 (10.5 oz) can of cream of mushroom soup – classic and cozy
- 1/2 cup sour cream – for that tangy, velvety texture
- 1/4 cup milk – just enough to loosen the sauce
- 1 tbsp Worcestershire sauce – adds that “what is that amazing flavor?” depth
- 1 tsp garlic powder
- 1/2 tsp black pepper
- 1/2 tsp salt (adjust to taste depending on your bacon and soup)
- 1/4 tsp smoked paprika (optional, but it adds a beautiful warmth)
- 1/2 cup French-fried onions, plus more for topping before serving
Instructions:
Step 1: Prep the Green Beans
If you’re using fresh green beans, give them a quick rinse and trim the ends. I like to snap them in half so they’re bite-sized. If using frozen, thaw and drain really well so you don’t end up with watery casserole.
Step 2: Mix the Creamy Base
In a medium bowl, whisk together the cream of mushroom soup, sour cream, milk, Worcestershire sauce, garlic powder, pepper, salt, and smoked paprika. Give it a little taste—yes, it’s okay to sneak a spoonful!
Step 3: Layer It All In
In your slow cooker, layer the green beans, chopped onion, and crumbled bacon. Pour the creamy sauce over top and gently stir everything together. Sprinkle in the French-fried onions and give one more light stir.
Step 4: Set and Forget
Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours. The green beans should be tender but not mushy, and everything will smell heavenly.
Step 5: Final Touch
Right before serving, sprinkle another handful of French-fried onions over the top. If your slow cooker has a “keep warm” setting, let it sit uncovered for 10–15 minutes to slightly thicken the sauce and crisp the topping.
👩🍳 Pro Tips for Success:
- Use thick-cut bacon so it holds its texture after slow cooking. Thin bacon can get lost in the sauce.
- Don’t skip the Worcestershire sauce—it’s the secret behind that Amish comfort-food richness!
- If you’re prepping ahead, you can mix everything (except the French-fried onions) the night before and store in the fridge. Just pop it in the slow cooker when ready.
- Add shredded rotisserie chicken to turn this into a full meal!
🧊 Storage & Serving Ideas:
- Storage: Let leftovers cool completely, then store in an airtight container in the fridge for up to 4 days. The flavor gets even better the next day!
- Reheating: Pop it in the microwave or warm in a saucepan over low heat. Add a splash of milk if it seems too thick.
Serving Suggestions:
- Pair with roasted chicken, pork chops, or meatloaf for a hearty dinner.
- Serve with buttered rolls and a side of mashed potatoes for the full comfort-food experience.
- Great on a buffet table—just keep it on the “warm” setting in the slow cooker.
