Green Bean Casserole with Frozen Green Beans


I always receive huge compliments when I make this tweaked version of the usual green bean casserole with frozen beans. The secret to this version is the added Swiss cheese. It is one of my favorite dishes for the holidays or anytime. I consider it a true comfort food.

  • 1 (16 ounce) package frozen cut green beans, thawed

  • 1 (10.5 ounce) can condensed cream of mushroom soup

  • ½ cup milk, or more to taste

  • ½ cup sour cream

  • ½ cup shredded Swiss cheese

  • 1 (2.8 ounce) package French-fried onions, divided

  • 1 teaspoon garlic salt

  • 1 teaspoon soy sauce

  • ground black pepper to taste


  1. Preheat the oven to 350 degrees F (175 degrees C).

  2. Mix green beans, condensed soup, 1/2 cup milk, sour cream, Swiss cheese, 1/2 of the French-fried onions, garlic salt, soy sauce, and pepper together in a large casserole dish.

  3. Bake, covered, for 30 minutes adding a little more milk halfway through the cooking time if a creamier consistency is desired.

  4. Remove from the oven and add remaining onions to the top. Bake, uncovered, until bubbly, about 15 more minutes.

Cook's Note:

You can use French-cut green beans instead of regular, but if you do, reduce the bake time by 15 minutes.
