Slow Cooker Cheesy Green Bean Casserole

Slow Cooker Cheesy Green Bean Casserole is the perfect holiday side dish and doesn't take up valuable oven space. It'll become a family favorite in no time.
Cook Time2 hours 30 minutes


  • 2 cans (10.5 oz each) Cream of Mushroom Soup (do not dilute with water)
  • 1/2 cup milk
  • pepper, to taste
  • 3 bags (12 oz each) frozen cut green beans (do not thaw)
  • 1 6 oz container of French fried onions, divided
  • 3 cups shredded sharp cheddar cheese, divided


  • In slow cooker, combine the soup, milk and pepper (to taste) - Stir until well blended.
  • Mix in the frozen green beans, about half of the container of fried onions, and half of the cheese.
  • Top the mixture with the remaining cheese.
  • Cover and cook on high for about 2.5 hours.
  • For the fried onions, I choose to toasted the onions in a small skillet (no oil or spray) until golden brown. Alternatively, you can top the casserole without toasting or browning them. If your slow cooker can go into the oven, you could also top the casserole with onions and place it in the broiler for a few minutes before serving.
