This is the classic, creamy green bean casserole recipe you need for Thanksgiving or Christmas. It uses simple ingredients and delivers the comforting flavor everyone expects, topped with crispy fried onions.

Ingredients

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

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 1.5-quart casserole dish.
  2. In a medium bowl, whisk together the cream of mushroom soup, milk, soy sauce, and black pepper until smooth.
  3. Stir in the drained green beans and half of the crispy fried onions into the soup mixture. Mix until everything is coated evenly.
  4. Pour the mixture into your prepared casserole dish.
  5. Bake for 25 minutes.
  6. Remove the dish from the oven and sprinkle the remaining crispy fried onions evenly over the top.
  7. Return the casserole to the oven and bake for another 5 minutes, or until the topping is golden brown and the casserole is bubbly.
  8. Let the casserole stand for 5 minutes before serving.

Notes

  • You can prepare the entire casserole, up to the final topping, up to one day ahead. Cover and refrigerate. Add 10 minutes to the initial baking time if baking from cold.
  • For a Southern green bean casserole twist, stir in 1/2 cup of shredded cheddar cheese with the green beans.
  • If you want to make this a homemade green bean casserole from scratch, substitute the canned soup with a homemade mushroom sauce.
