Slow Cooker Green Bean Casserole is a classic Thanksgiving side dish that many of us have enjoyed for years. I'm showing you how to make Green Bean Casserole in the crockpot, and it's so easy (and saves room in your oven). This is the quick traditional version of crockpot Green Bean Casserole, and it's delicious!

I think what I like the most about this Crockpot Green Bean Casserole recipe is the French fried onions. Adding them at the end, after lightly browning them on the stove, prevents them from getting soggy and brings out the flavor.

Slow Cooker Green Bean Casserole

Whether you are looking for a delicious and easy side dish recipe for Thanksgiving, or a slow cooker vegetarian recipe, this classic Green Bean Casserole made in the slow cooker is a great option.

This recipe is a more convenient version of the original Green Bean Casserole, mainly because you use canned green beans.

Each bite is creamy and delicious!

Which Green Beans are Best to Use?

You have the option of using the green beans you like.
• Though this recipe uses canned, the original recipe uses fresh green beans (see notes on preparation in recipe card).
• Cut canned green beans are what I use, however many people really like using the canned French style cut green beans.

What If I Don't Like Mushrooms?

I get asked this a lot, I guess there are a lot of folks who don't care for mushrooms. No worries!
• Use cream of chicken soup instead.
• Use cream of celery soup, or one cream of chicken and one celery.

(If you are using fresh green beans, blanch them for 5 minutes in boiling water and then transfer to ice water. Then drain and add to the crock.)

    I am going to make this for Thanksgiving and wanted to know if the Hamilton Beach slow cooker you use is the 7 quart since I am shopping for a new one. Thank you!

      I do have a 7-quart, though the one in the photo is a 4-quart. I suggest a 6 or 7 quart if you are only going to have one slow cooker. Just be careful when making small batch recipes as they will cook faster in a larger crock. I really like the slow cookers that automatically switch to Warm when the cook time is finished. That way if you aren't home or are busy your food won't burn!
