How many does this serve?

Can you brown the fried onions?

I usually don’t mess with browning the fried onions but you definitely can if you prefer.

There are 2 ways that you can brown the fried onions on top of this green bean casserole.

First, if you have an oven safe crock pot insert (with no plastic on it). You can remove the insert and broil the casserole for 2-3 minutes to brown the onions on top.

The second option is to brown the fried onions in a small amount of butter in a skillet over medium heat. Then place them on top of the casserole in the crock pot.

Variations for slow cooker green bean casserole:

  • Change the Cream of soup – If you’re not a cream of mushroom soup fan, switch it out for cream of chicken soup or cream of celery.
  • Use Frozen or Fresh Green Beans – You can use fresh or frozen green beans. I do recommend that you let the frozen green beans thaw slightly before placing them in the crockpot. Otherwise, they tend to make the green bean casserole a little too watery.
  • Make it Cheesy – Use canned cheddar soup in place of the cream of mushroom for a cheesy green bean casserole.
  • Top with parmesan cheese – Parmesan cheese is a great addition to green bean casserole. Sprinkle about ½ cup on top when you top with the extra fried onions to jazz up this classic casserole.
  • Add more Seasonings – I like to keep this recipe very simple with the ingredients. However black pepper, onion powder, garlic powder, or even Worcestershire sauce are great additions to this easy recipe.

Crockpot Green Bean Casserole Tips

Since this is a crockpot recipe, it does have a little longer cooking time than traditional green bean casserole. Keep that in mind when you’re planning out your dishes.

I like to go ahead and prep and get this green bean casserole going first thing. If needed, you can always switch it to warm.

How to Store:

If you have any leftovers, store them in an air tight container in the refrigerator for up to 4-5 days.

It’s best reheat in the oven to make the fried onions crispy again but you can heat them up in the microwave as well.

Frequently Asked Questions

Can this be made ahead of time?

Yes, this can be made ahead of time. Mix together the ingredients in a bowl, cover and refrigerate for up to 3 days.

Can you use fresh or frozen green beans?

I prefer canned green beans in this recipe but you can easily use fresh or frozen. If fresh, make sure to trim them first.

You will need approximately 3 cups of green beans and I would cook on low for 4-6 hours or on high for 3 hours until the beans are tender. Fresh or frozen green beans take longer to cook in a crock pot.

How long can you keep this on warm?

After the green bean casserole is done cooking you can keep this on warm for up to 3 hours. That makes this recipe great for Thanksgiving and Christmas dinners.

How do you keep green bean casserole from being soupy?

If you find your casserole to be runnier than you’d like, remove the lid and cook for 30 minutes without the lid. That will help thicken the casserole.
