Slow Cooker Green Bean Casserole

Any Thanksgiving menu is not complete without a creamy, savory, green bean casserole! Crockpot green bean casserole is an alternative to crispy tender green beans and a traditional side for Christmas dinner as well as a Thanksgiving side dish.

It’s classic comfort food that has just a few ingredients and making slow cooker green beans takes the time and pressure off so you can focus on the oven roasted turkey or baked ham. We also love these bacon wrapped green bean bundles!

Recipe Ingredients

  • Green beans: I prefer canned green beans for their softer texture, I have not tested this with fresh green beans. You will need 3 cans.
  • Chicken broth: Adds flavor and prevents the crockpot green bean casserole from drying out.
  • Cream of mushroom soup: You could use cream of chicken soup if preferred but taste will be different.
  • Salted butter: Since we are not adding salt, salted butter is best.
  • French Fried Onions: A staple for green bean casserole!

How to Make Crockpot Green Bean Casserole

  • Assemble. Place green beans in crock pot. Whisk together the cream of mushroom and chicken broth and pour on top of green beans. Place slabs of butter across the top.
  • Cook. Cook on low for 2-3 hours or high for 1-2 hours. Stir halfway through and add salt and pepper to taste. Top with french fried onions just before serving.

Tips for Success

  • Make sure to grease the crockpot first to prevent sticking once it’s ready.
  • Drain the canned beans. Too much extra liquid will make for a soggy dish.
  • Save the French fried onions to top it off just before serving. They won’t stay crispy if you add it right into the crockpot.
  • Easily double the recipe for a crowd. The cooking time remains the same.
  • For a bit of added flavor and texture add in sliced mushrooms and onions.
  • If you’re going to add cheese, add it in towards the end or along with the crispy fried onions. Cheddar and parmesan are both great choices.
  • Keep it warm for up to 2 hours until you’re ready to serve.

FAQs

Can I use fresh or frozen green beans?

You can! If using fresh, you’ll want to use more because a can holds more beans as they are softer sitting in liquid. Don’t forget to wash and trim the ends.
If using frozen, be sure to thaw them first. You don’t want all of that excess liquid.

Can I make this ahead of time?

If you’re planning ahead and want to prepare this dish the day before, you can. Assemble the casserole in the crockpot as instructed, cover with foil, and place in the fridge. The following afternoon, set the cooking time.

How long can I keep the casserole on the warm setting?

Up to two or three hours which makes it perfect for Thanksgiving or Christmas dinner!

How to avoid the green bean casserole from being soup?

If you find that your casserole is soupier than you would like, remove the lid for 30 minutes to help thicken it.

How to store leftovers?

Store in the refrigerator in an airtight container for up to 4-5 days. Reheat in the oven for crispy fried onions or in the microwave.
