Green Bean Casserole

A Creamy Mushroom Sauce

The heart of green bean casserole is the creamy mushroom sauce. This sauce is made with condensed cream of mushroom soup, milk, and salt and pepper. The soup provides a rich, creamy base for the sauce, while the milk thins it out and adds a touch of sweetness. The salt and pepper season the sauce to taste.

Crunchy Onion Topping

The crunchy onion topping is what makes green bean casserole so irresistible. This topping is made with crispy fried onions, which add a layer of texture and flavor to the casserole. The onions also add a bit of sweetness and a touch of bitterness, which balances out the richness of the sauce.


  • 1 (10.5-ounce) can condensed cream of mushroom soup
  • 1/2 cup milk
  • 1/4 teaspoon black pepper
  • 4 cups cooked green beans, drained
  • 2/3 cup crispy fried onions, divided


  1. Preheat oven to 350 degrees F (175 degrees C).
  2. In a 1 1/2-quart casserole dish, combine soup, milk, and pepper.
  3. Stir in green beans and 2/3 cup of the crispy fried onions.
  4. Bake for 25-30 minutes, or until bubbly.
  5. Sprinkle with remaining 1/3 cup crispy fried onions.
  6. Bake for an additional 5 minutes, or until onions are golden brown.


  • For a richer flavor, use whole milk instead of skim milk.
  • If you don’t have crispy fried onions, you can substitute French’s® Original Crispy Fried Onions.
  • For a more flavorful casserole, add 1/4 cup grated Parmesan cheese to the soup mixture.
  • If you are short on time, you can use canned green beans instead of fresh or frozen green beans.
  • To make ahead of time, assemble the casserole and bake for 25 minutes. Cover and refrigerate for up to 24 hours. Bake for an additional 5 minutes before serving.
