- Green beans (58 oz.): Fresh cut, French style, or thawed frozen beans give you that signature tender crunch.
- Condensed cream of mushroom soup (21 oz.): The heart of the casserole’s creamy base, you can also swap it with cream of chicken soup for a subtle twist.
- Milk (¾ cup): Adds smoothness—using heavy cream or half-and-half makes it extra rich and indulgent.
- Sour cream (¼ cup): Brings a tangy creaminess that balances the flavors perfectly.
- Garlic powder (½ tsp): Adds a gentle savory depth without overpowering the dish.
- Kosher salt (½ tsp): Enhances all the flavors, making every bite sing.
- Ground black pepper (½ tsp): Gives a subtle kick that complements the creamy texture.
- Freshly shredded Parmesan cheese (½ cup): Delivers a nutty, salty finish that melts right into the sauce.
- French fried onions (6 oz., divided): The unbeatable crunchy topping that brings texture contrast and a hint of indulgence.
How to Make Crockpot Green Bean Casserole Recipe
Step 1: Mix the Creamy Base
Begin by adding the condensed cream of mushroom soup, milk, sour cream, garlic powder, kosher salt, ground black pepper, and shredded Parmesan cheese right into the bottom of your crockpot. Using a wooden spoon or spatula, give everything a good stir until the mixture looks smooth and fully combined. This creamy base is what will gently envelop the green beans and keep them luscious and flavorful during the cooking process.
Step 2: Add the Green Beans and Some Crunch
Next, pour in the green beans along with half of your French fried onions. The onions folded in at this point start softening and releasing flavor into the casserole without losing their character completely. Stir everything together just until the green beans are evenly coated with the creamy mixture—no need to overmix here.
Step 3: Slow Cook to Perfection
Cover your crockpot and set it to low heat. Let the casserole cook gently for 2 to 3 hours. This slow cooking is key—it steeps the green beans in that rich sauce, making them tender but still holding a slight bite that’s so satisfying.
Step 4: Finish with Crispy Topping
Once the cooking time is up, give your casserole a good stir to redistribute the sauce and soften everything evenly. Then sprinkle the remaining French fried onions generously over the top and cover for a few minutes longer if you like them a bit softened, or leave uncovered to keep them ultra crisp. This final touch adds a festival of textures from creamy to crunchy.

Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftovers into an airtight container and store them in the refrigerator. The casserole will stay fresh and ready to enjoy for up to 3 days, making it an excellent make-ahead dish for busy days or next-day meals.
Freezing
This Crockpot Green Bean Casserole Recipe freezes well! Simply freeze in a suitable container without adding the crispy onions on top, as they can become soggy during freezing. Add fresh fried onions only after reheating to maintain that glorious crunch.
Reheating
Reheat leftovers gently in the microwave or in an oven-safe dish at 350°F (175°C) until heated through. For best results, add extra French fried onions after reheating to revive that irresistible crispness that defines this dish.
FAQs
Can I use fresh green beans instead of canned or frozen?
Absolutely! Fresh green beans work wonderfully in this recipe. Just be sure to trim and cut them into bite-sized pieces and blanch them briefly before adding to the crockpot for the best texture.
Is it possible to make this casserole vegetarian?
Yes! Use cream of mushroom soup instead of cream of chicken, and double-check that your French fried onions do not contain any animal-derived ingredients. This makes for a delicious vegetarian-friendly option.
How can I make this recipe dairy-free?
To make a dairy-free version, swap the milk and sour cream with your favorite plant-based alternatives like almond milk and coconut cream, and use a dairy-free cheese substitute or leave the cheese out altogether.
Can I prepare this recipe in advance and cook it later?
Definitely! Combine all the ingredients except the French fried onions in the crockpot insert, cover, and refrigerate overnight. When ready, cook on low for 2-3 hours and add the remaining onions just before serving.
What do I do if my crockpot runs hotter than expected?
If your slow cooker tends to run hot, check the casserole after 1.5 to 2 hours to avoid overcooking the green beans. You might also consider cooking at the warm setting and adjusting as necessary until you are familiar with your appliance’s temperament.
