Slow Cooker Green Bean Casserole is the easiest way to make everyones favorite Thanksgiving side dish! Make using fresh or canned green beans!
I originally posted this recipe back in November 2016, the recipe stays the same, we’ve added some updated instructions and new photos! It’s definitely safe to say that green bean casserole is my favorite side dish at Thanksgiving and Christmas. This is more of a classic, using canned green beans and soup. If you’re here looking for a homemade version, be sure to try our baked Green Bean Casserole from scratch!
Slow Cooker Green Bean Casserole:
This recipe works out perfectly with fresh, or canned green beans and I’ve given directions for both in the recipe card. You can also use frozen if you want, but, you’ll have best results if you thaw them first. Throwing them in frozen seems to make the casserole watery. What I love so much about this is that I can mix everything up right in the slow cooker, put on the lid, and then just top with extra french fried onions about 30 minutes before serving.
Recipe Tips:
- Plan ahead! This recipe takes 2 hours on low in the crockpot, plus another 30 minutes after you top with the french onions.
- You can make this in advance. Simply mix everything together in a large mixing bowl, cover with plastic wrap and refrigerate for up to 3 days.
- If you absolutely hate cream of mushroom soup, then cream of chicken or even cheddar cheese soup work great here as well.
- The cheese is optional! We love the cheddar and parmesan, but you can leave them out if that’s your preference, or sub in your favorite kind of cheese.

I am excited to try this recipe. What size crockpot does it take?
Hi! 6 quart or larger 🙂
If I use fresh green beans, do I need to precook it – if not will the fresh green beans cook enough after alloted time?
Looking forward to making this for Thanksgiving! Can I double the recipe, and if so, how would that affect the cooking time? Thanks!
Yes, you should be able to double it and just make sure your crockpot is large enough! As far as cook time, it should be about the same.
Doubled the recipe, cooked it for the same time…PERFECT! Thank you!! 🙂
Is the cooking time the same for fresh green beans?
Yes 🙂
I have a very picky eater, is there something I can use instead of the cream of mushroom?
Cream of chicken or condensed cheddar cheese soup would work just as well! 🙂
Comfort food at it’s best. Full on green vegetables too! Anything that will help me feed the kids with some nutritious green veggies… I’m sold!
This one of the best green bean casserole recipe. I like the cheesy version. I make with cream of mushroom but not added cheese to it.
I think it just helps me further feed my cheese addiction, but that’s ok with me! 🙂
Who doesn’t just love that green bean, cheesy casserole. This is awesome that you can make it in the crock pot! It looks so good!
A cheesy casserole? Count me in – this looks so delicious!
I love that this can be made in a slow cooker. That will help save oven space when cooking a large meal.
Agreed, that’s exactly why I love it! 🙂
