Ingredients

Scale

Vegetables

58 oz. green beans (fresh cut or French style, drained if canned; if frozen, thaw first)

Condiments & Dairy

21 oz. condensed cream of mushroom soup (2 cans; cream of chicken soup can be substituted)
¾ cup milk (heavy cream or half-and-half can be used for a richer casserole)
¼ cup sour cream
½ cup freshly shredded Parmesan cheese

Seasonings

½ tsp garlic powder
½ tsp kosher salt
½ tsp ground black pepper

Toppings

6 oz. French fried onions (divided; 1 container)

Instructions

Prepare the base mixture: Add the condensed cream of mushroom soup, milk, sour cream, garlic powder, kosher salt, ground black pepper, and freshly shredded Parmesan cheese to the bottom of the crockpot. Use a wooden spoon or spatula to thoroughly stir the ingredients together until well combined and smooth.
Add the green beans and onions: Stir in the green beans along with half of the French fried onions into the base mixture. Mix gently until the beans and onions are evenly coated and just combined, being careful not to break up the green beans.
Cook the casserole: Cover the crockpot with its lid and cook on the low setting for 2 to 3 hours. During this time, the flavors meld and the green beans soften to the perfect tenderness without becoming mushy.
Serve with crispy topping: Before serving, give the casserole a good stir to evenly distribute any cooked mixture. Then sprinkle the remaining French fried onions on top to add a crispy, crunchy texture. Serve the casserole warm as a delicious side dish or comfort meal.

Notes

Using fresh or canned green beans works equally well; canned must be drained, and frozen beans should be thawed prior to cooking.
For a richer flavor, substitute milk with heavy cream or half-and-half.
French fried onions added at the end keep their crunch; avoid mixing them in before cooking to maintain texture.
You can substitute cream of chicken soup if preferred for a slightly different flavor.
Cooking times may vary slightly depending on your crockpot model; start checking doneness after 2 hours.
If you prefer a thicker casserole, reduce the milk slightly or add more cheese.
