Slow Cooker Green Bean Casserole is the EASIEST way to make this classic side. Cooking green bean casserole in a crockpot frees up oven space!
Green bean casserole is a must at every holiday dinner. The creamy, crunchy combination is fantastic!
Since green bean casserole is a mix-and-heat side dish, it is the perfect thing to cook in a slow cooker. Just mix it up, turn the crockpot on, and forget about it while you focus on the other dishes.

How To Make Slow Cooker Green Bean Casserole
- Put three cans of drained green in a slow cooker.
- For this recipe, I used canned green beans, but about five cups of fresh or frozen green beans could be used as well.
- If using fresh green beans, trim and cook them until tender. When using frozen green beans, cook them until tender, following the instructions on the package.
- Put cream of celery soup, milk, Worcestershire sauce, onion powder, garlic powder, and black pepper in a small bowl.
- We use cream of celery soup in our green bean casserole, but many of the condensed cream soups would work as well. Choose your favorite, or use a combination of soups.
- Many of the recipes for green bean casserole call for cream of mushroom, but my family doesn’t like mushrooms. I’ve also made green bean casserole with cream of chicken soup, and we like it that way, too.
Stir the soup mixture to combine. The ingredients could be added directly to the slow cooker with the green beans, making less dirty dishes, but it is harder to mix up and to make sure the seasonings are distributed that way.
Add the soup mixture to the slow cooker and gently stir to evenly coat the beans.
Add the cover and cook on low for 4-5 hours or high for 3-4 hours or until heated through.
Stir in one cup of French fried onions and then top with the remaining onions before serving.
If you need to put the lid back on the slow cooker green bean casserole, drape a couple of paper towels over the slow cooker before adding the lid. This will help to keep the condensation off of the French-fried onions.
