  • Preheat oven to 350 degrees F. Spray a 1 ½ -quart baking dish with cooking spray and set aside.
  • Place frozen green beans in a large microwave-safe bowl. Add a splash of water, cover, and microwave just until crisp-tender (about 5 minutes). Drain and return green beans to the bowl.
  • Add condensed soup, milk, soy sauce, pepper, and ⅔ cup of the fried onions to the bowl with the green beans; stir to combine.
  • Transfer the green bean mixture to the prepared baking dish.
  • Bake, uncovered, for 25 minutes.
  • Stir, sprinkle remaining ⅔ cup of fried onions on top, and bake for about 5 more minutes.


  • Swap out the frozen French-cut green beans and use 4 cups of frozen cut green beans, 4 cups of cut fresh green beans, or 2 (14.5 ounce) cans canned green beans (drained). If using frozen or fresh green beans, cook in the microwave until crisp-tender (about 5 minutes for frozen or 8 minutes for fresh).
  • Instead of the cream of mushroom soup, use a different flavor of condensed soup. Cream of chicken or cream of celery would both be good in this recipe.
  • Add cooked, chopped bacon to the green bean mixture, or sprinkle cooked bacon on top of the dish during the final few minutes to get nice and crispy.
  • Sauté sliced fresh mushrooms and stir them into the green bean casserole before baking.
  • Add 1 cup of grated cheese to the casserole before baking. Sharp cheddar cheese would be perfect!
  • To serve a larger crowd, double all of the ingredients and bake the casserole in a 3-quart dish. This larger casserole will serve about 12 people. If you need to serve 20 people, I recommend preparing two large casseroles (3 quarts each), which will require 4 times as many ingredients.
