Slow Cooker Cheesy Green Bean Casserole
Enjoy this Slow Cooker Green Bean Casserole, a delicious twist on the classic holiday side dish. This comforting and easy-to-prepare recipe is a crowd-pleaser and a staple for Thanksgiving, Christmas, and other festive meals. Slow cooker recipes are especially handy during holidays when your oven’s packed with the main entree or other dishes.
Using the crock pot to make this green bean casserole with cheese is such a timesaver, and the result is tender green beans slow-cooked in a cheesy cream sauce topped with traditional fried onions. It’s a timeless favorite made even better!
The first time I had green bean casserole was many years ago and I was totally in love with the dish. I wanted to change it up so I made this Slow Cooker Cheesy Green Bean Casserole. It did not disappoint and the leftovers were even better.
When you make this, you free up a little oven space for these Super Easy Rosemary Dinner Rolls or this Yummy Sweet Potato Casserole. Or, perhaps you’ll want to make these Cheesy Smashed Roasted Brussels Sprouts with your dinner. No matter what’s on the menu, the green bean and cheese casserole is going to be the hit of the side dishes.
Slow Cooker Cheesy Green Bean Casserole
Just like the traditional oven-baked version, this slow cooker casserole use the cream of mushroom soup and the famous brand of crispy onion pieces. This recipe does not use canned beans, you can but I didn’t want to have them be overcooked or mushy. Instead, I used frozen green beans and did not thaw them. You can use fresh as well. I like the beans to be cooked to a crisp-tender bite. If you prefer a softer bite, cook them a little longer.
Timesaving Tips and Variations
- In place of the mushroom soup, use cream of chicken or cream of celery or onion.
- You can also make a Homemade Condensed Cream of Chicken Soup to use in this.
- Sharp cheddar is the cheese I used, but you could use a white cheddar, or add a bit of zing with Pepper Jack cheese.
- Using the crockpot, the crisp onions won’t brown as they would in the oven. You can top the baked dish with them as is or you can take a couple of minutes and brown them in a skillet, then add before serving.
- Get creative with leftovers, add a bit of the vegetable dish to these Air Fryer Thanksgiving Egg Rolls
A few simple tweaks can take your dish from good to absolutely unforgettable.
How do you store leftover green bean casserole?
Transfer leftovers to an airtight container and refrigerate for up to three days. Reheat in the oven at a low temperature to maintain the creamy texture, or use a microwave for a quicker option. A splash of milk may be needed.

Directions to Make Slow Cooker Cheesy Green Bean Casserole
In a slow cooker, combine the soup, milk, and salt and pepper (to taste) – Stir until well blended. Mix in the frozen green beans, about half of the container of fried onions, and half of the cheese.
Top the mixture with the remaining cheese. Cover and cook on high for about 2.5 hours.
For the fried onions, I choose to toast the onions in a small skillet (no oil or spray) until golden brown. Watch them closely. Alternatively, you can top the casserole without toasting or browning them. If your slow cooker can go into the oven, you could also top the casserole with onions and place it in the broiler for a few minutes before serving.

Great idea to make this in the slow cooker when oven space is at a premium.
This is definitely a keeper for the holiday table. TFS and have a wonderful week.
Love that this is made in the crock-pot. It’s always nice to have things made that don’t go in the oven!
Sounds perfect! Yes frozen green beans are so much better than canned!
What haven’t I put cheese on this casserole before!? What a delicious idea!
Exactly what I said! Then I did!
I’ve been searching for slow cooker recipes made with frozen green beans, but I’m getting confused. Some say you must thaw and drain frozen beans or the result will be too soupy. Others say to just throw them in frozen. Maybe the extra liquid from the beans will help thin the condensed soup?? This recipe sounds the easiest, but wondering if the sauce ends up too thin?
Jodi, The sauce in this recipe doesn’t end up too thin at all. It just helps thin the soup a little more. The amount of liquid that comes from the beans really isn’t much and you are only adding a little milk to help thin out the soup. We’ve never had it be too “soupy” or liquidity.
A holiday classic without taking up oven space. That is a win!!
Yes! Love slow cooker recipes for that reason.
You can’t go wrong with cheesy green beans and I love that this is made in the slow cooker to give some more room in the oven!
I never have enough oven space!
I’ll bet this is one of those “stealth” dishes, where everyone takes some and then goes back for seconds and there ends up being none left. (That would be me.)
Oh for sure! It’s also a recipe where one will hid leftovers so no one will eat them but said person…me.
I love that you make these in the slow cooker. Anything that you don’t have to fuss over at the last minute is great.
Exactly, just dump, mix and go!
Slow cooker recipes are always appreciated for the holidays because I never seem to have enough oven space. I like to use the fried jalapeno strings to top casseroles, give it that extra oomph!
Those are great to use, too. I’m always being told to add more spice to things lol
I’m stealing this recipe for the holidays this year. One less thing in the oven! I never had green bean casserole until I met the hubs. Now it’s a staple at every holiday meal.
I made it again and tested pepperjack cheese…it was so good!
