Make the classic, creamy Green Bean Casserole using simple ingredients. This easy recipe is a beloved holiday side dish that always pleases a crowd.

Ingredients

Scale
  • 2 (14.5 ounce) cans cut green beans, drained
  • 1 (10.5 ounce) can condensed cream of mushroom soup
  • 1/2 cup milk
  • 1 teaspoon soy sauce
  • 1/4 teaspoon black pepper
  • 1 1/3 cups crispy fried onions

Instructions

  1. Preheat your oven to 350 degrees Fahrenheit. Lightly grease a 1.5-quart casserole dish.
  2. In a large bowl, combine the drained green beans, cream of mushroom soup, milk, soy sauce, and black pepper. Mix until everything is well combined.
  3. Pour the bean mixture into the prepared casserole dish, spreading it evenly.
  4. Bake for 25 minutes.
  5. Remove the casserole from the oven. Sprinkle 3/4 cup of the crispy fried onions evenly over the top.
  6. Return the casserole to the oven and bake for an additional 5 minutes, or until the topping is golden brown and the casserole is bubbly.
  7. Remove from the oven and let it stand for 5 minutes before serving. Top with the remaining 2/3 cup of crispy fried onions just before you serve it.

Notes

  • You can prepare this casserole ahead of time. Assemble the entire dish, cover it, and refrigerate for up to one day. Add 10 minutes to the initial baking time if baking directly from the refrigerator.
  • For a Southern style variation, add 1/2 cup shredded sharp cheddar cheese to the soup mixture before baking.
  • If you do not have canned soup, you can make a homemade cream of mushroom sauce using fresh mushrooms, flour, butter, and broth.
