Crockpot Green Bean Casserole

This Crockpot Green Bean Casserole is made with fresh beans and doesn’t use canned soup. It’s a yummy and easy upgrade to a classic dish, and doesn’t take up oven space for a holiday meal!

Hey there, friends. I tested this recipe four times to get it just right for you. I wanted to make green bean casserole in a crockpot. But I wanted to use fresh green beans and fresh mushrooms, and no gloopy canned cream of mushroom soup.

It took me many tries to get just the right balance of cooked but not mushy, saucy but not too liquidy, and so on.

This is perfect for Thanksgiving or Easter dinner, alongside a baked ham with pineapple sauce and shrimp deviled eggs.

If green bean casserole isn’t your thing, be sure to add my balsamic green beans to your Thanksgiving recipes list along with my roasted turkey with maple bourbon glaze. But if you’re a casserole lover, read on!

Can I make Green Bean Casserole in a crockpot?

Yes, and the best way to do that is 4 hours on HIGH. I did test it separately for 8 hours on low, and everything just got too mushy. 4 hours on high is plenty to cook the beans but not overcook them.

What you’ll need for this crockpot green bean casserole recipe:

• green beans
• mushrooms (if you have extra, make mushroom tacos or savory oatmeal!)
• french fried onions
• garlic
• sour cream (also integral for slow cooker beef stroganoff and chicken stroganoff)
• chicken broth
• Parmesan cheese
• Worcestershire sauce
• salt and pepper

Can I make green bean casserole the night before?

If you want to prep this the night before, I would suggest stirring the sauce together (Step 1) and keeping it in a covered container in the fridge. I would also trim and cut the green beans, and cut the mushrooms, and keep those in separate zip-top bags in the fridge.

Then, 4 hours before I want to serve, I would just stir everything together in the crockpot bowl and turn it on!

Psst – you can also make gravy from scratch and the fruit dip for my Easter fruit salad in advance of your holiday meal!

How much green bean casserole for 4? Can I double this recipe?

This recipe makes 4 generous side dish servings (or maybe more like 6 if you have lots of other side dishes like Dr. Pepper baked beans and Thanksgiving Fruit Salad or Christmas Fruit Salad with your holiday meal).

You can definitely double this recipe with the same results, but you’ll need a bigger crockpot! I tested the 4-serving version you see below in a 3-quart crockpot. Fresh green beans take up quite a bit of room in the pot when they’re raw, so most of the pot was full at the beginning (they cook way down later).

To make a double batch, you’ll need a bigger crockpot. A 5-quart or larger crock pot should do the trick for a double batch. I tested a double batch in my 6.5-quart crockpot and it turned out great (a larger slow cooker also comes in handy when I want to make crock pot ribs).
