Expert Tips

  • Stir in 1/2 teaspoon of garlic powder, ground sage or thyme to the soup mixture to suit your family’s preference.
  • Not a fan of canned green beans? You can easily swap those out for frozen beans. If you are using frozen green beans in this easy green bean casserole, you'll need 2 (14.4 oz) bags. Simply give them a quick rinse under cool water and shake of the excess water before adding to the casserole or thaw in the refrigerator overnight and drain before using.
  • French fried onions on top of green bean casserole is one of the most traditional (and delicious) ways to serve it to a group, but you can opt for other crunchy toppings as well. Chopped toasted walnuts, sliced green onions, or chopped cooked bacon sprinkled on top after baking are all tasty alternatives!
  • If you have any leftovers, you can store this green bean casserole in a tightly sealed container in the refrigerator for about 3 days. Freezing leftovers is not recommended.
  • No oven space on Thanksgiving Day? You can make green bean casserole in the slow cooker—follow this Slow-Cooker Alfredo Green Bean Casserole for a delicious alternative.

More About This Recipe

  • It seems that green bean casserole has been showing up on dinner tables for as long as we can remember. Thanksgiving dinner just wouldn’t be the same without this classic, quintessential holiday side.

Since its humble beginnings, the dish has become legendary—so much so, that the original recipe card now lives at the National Inventor’s Hall of Fame. Since the recipe was introduced, there have been several variations on the original, swapping in ingredients and using different cooking techniques to create a beloved, individual tradition for families.
