Slow Cooker Green Bean Casserole

Any Thanksgiving menu is not complete without a creamy, savory, green bean casserole with or without cheese. This casserole recipe is an alternative to crispy tender green beans which has become a traditional side for Christmas dinner as well as a Thanksgiving side dish.

It’s classic comfort food that is so simple to make with just a few ingredients and using the slow cooker takes the time and pressure off so you can focus on the main event. It doesn’t get any easier!

Serve alongside an oven roasted turkey or baked ham for a delicious holiday meal that your family will love!

Easy Dump-and-Set Side Dish

A dump-and-set dish means that once you grease the crockpot, you place all the ingredients in, starting with the beans, then combined broth and soup, add in the seasoning and butter, you close the lid, set it, and walk away. That’s it!

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.

Can I Use Fresh or Frozen Beans Instead?

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.

Make Ahead

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.
