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.

Frequently Asked Questions
Yes, bake at 350° for 35 minutes or until hot. Add the French fried onions and bake for an additional 5 minutes, until golden brown.
Brown the French fried onions in a skillet over medium-high heat for 3-4 minutes before topping the green bean casserole. Otherwise, remove the crock pot insert from the slow cooker, remove the lid, and put the crock pot insert in the oven. Bake at 350° for 10 minutes until the French fried onions are golden. Then, return the insert to the slow cooker.
Yes, you can reduce the cooking time in the slow cooker by heating up the green beans and soup mixture in the microwave before adding them to the crockpot.
If the green bean casserole looks too soupy near the end of the cooking time, take the cover off of the slow cooker (fully or partially) to allow some of the liquid to evaporate for the last 1/2 hour.
As long as you have enough room in your slow cooker, you can double or triple the recipe. Keep in mind that the more ingredients you have in the crock pot, the longer it will take for the casserole to warm up.

I made this for Thanksgiving using cream of chicken soup like the recipe suggests instead of cream of mushroom and it was a hit! Definitely try this recipe next time you make green bean casserole!
Carlie says
Such an awesome and easy dish! Takes even better than the regular green bean casserole.
Lidia says
Can you add the fried onions in when adding the soup??
Tonia says
Yes you can. They get much softer if you add them right away though.
x says
Any recommendations how to adjust the recipe if you’re adding cheese?Let’s say a cup’s worth. Like adding more milk or creamed soup?
Tonia says
I don’t think you have to make any adjustments if you want to add a cup of cheese. Just go ahead and stir it in! Sounds like a yummy addition! Happy thanksgiving!
Mike says
Much better with cream of mushrooms soup and a cup of chopped portobellos
Tonia says
Sounds like a great addition for the mushroom lovers! Happy thanksgiving!
Kali says
Hi! How would I adjust the recipe if I wanted to use fresh green beans? It looks delish!
Thanks!
Tonia says
Hi Kali,
I would suggest steaming the fresh green beans before preparing the casserole. Three 14.5 oz cans of green beans would be 2 1/4 pounds of fresh green beans.
Happy thanksgiving!

Perfect recipe. Not too soupy and not too dry. I doubled the recipe. The Worcheshire sauce and spices add so much. Thank you!
Joanne says
This is better than the recipe that comes on the box of French fried onions. In fact, it’s excellent! Must be the addition of Worcestershire sauce and garlic powder. Thanks!
Tonia says
Thanks so much, Joanne! I’m delighted to hear that! ~Tonia
Ginny says
What size crock pot is used for the green bean casserole with 3 cans of green beans? Thank you!
Tonia says
Hi Ginny,
I used my 3-quart oval crock pot for 3 cans of green beans. The one that I have is wide and shallow.
If you don’t have that size, you can make it in a larger one. There will just be more space above the casserole in the slow cooker.
Happy Thanksgiving!

Ginny says
Thanks so much, Tonia. Happy Thanksgiving to you and your family!
Renee Wagner says
How much time do you add if doubling or tripling recipe?
Tonia says
Hi Renee,
You shouldn’t have to add much time…maybe 1/2 hour to an hour. I would suggest checking it to see if it is hot after cooking it low for 4-5 hours or high for 3-4 hours. Then, add more time if necessary. It is it hot enough, you can turn the temperature down to warm until serving time.
Happy Thanksgiving!
