Fresh green beans (frozen and canned work great too!) simmer with canned cream of chicken and cream of mushroom soup, then get topped with crispy fried onions in the slow cooker. No bacon or ham required — my version is a vegetarian-friendly side dish that’s fancy enough for Thanksgiving and Christmas, but easy enough for weeknight meals, too! Yields 8 servings.

Crockpot Green Bean Casserole

Fresh green beans are best, but…

I’m a gardener, so naturally I’ll tell you—nothing beats fresh green beans in this recipe. But hey, if you’ve got frozen or canned on hand, they’ll still get the job done too! Instead of using 3 pounds fresh green beans, use (3) 16-ounce bags of frozen cut green beans or (4) 14-ounce cans of cut green beans (drain them first). If you are using frozen green beans I recommend thawing them first.

Storing Leftovers

Allow the casserole to cool completely, then transfer it to an airtight container. Store in the refrigerator for up to 4 days. Heat in a microwave-safe dish in 30-second intervals, stirring between each. Add fresh fried onions on top for extra crunch.
