Slow Cooker Green Bean & Alfredo Casserole

  • Cooking Time:

    3 - 4 hours on High
  • Servings:



26 oz. cut green beans, frozen (family size bag)
1 Sweet Onion (like Vidalia), chopped
2 Cloves Garlic, minced
1 Fresh Red Bell Pepper, seeded & diced
4 oz. Can, Sliced Mushrooms
1/4 tsp. salt
1/8 tsp. pepper
16 oz. container Alfredo sauce
1 c. Shredded Swiss Cheese
1 1/2 c. French fried onions, divided

Green bean Casserole is a favorite vegetable side dish during the holidays.   You will love this Slow Cooker Green Bean & Alfredo Casserole – it’s a twist on the classic and so yummy. We never go without the canned mushrooms – something that gives this a little added flavor and texture.  My family especially loves the topping of crisp French fried onions from the skillet!

  1. In a 4-6 quart slow cooker, combine all ingredients EXCEPT the swiss cheese and 3/4 c. of the French fried onions.
  2. Cover.  Cook on High for 3 hours.
  3. Remove lid and stir in 1 c. shredded swiss cheese.
  4. Replace lid and cook one additional hour.
  5. Just before serving, heat remaining French fried onions in a toaster oven to get them nice and crisp.
  6. Serve casserole topped with the toasted hot onions.

Happy Crocking!
