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, divided

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 1.5-quart casserole dish.
  2. In a medium bowl, combine the drained green beans, cream of mushroom soup, milk, soy sauce, and black pepper. Stir until everything is mixed well.
  3. Fold in 1 cup of the crispy fried onions into the green bean mixture.
  4. Spread the mixture evenly into your prepared casserole dish.
  5. Bake for 25 minutes.
  6. Remove the casserole from the oven and sprinkle the remaining 1/3 cup of crispy fried onions evenly over the top.
  7. 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.
  8. Let it cool for a few minutes before serving.

Notes

  • You can prepare this entire casserole ahead of time. Cover it and refrigerate for up to 24 hours. Add about 10 minutes to the initial baking time if baking straight from the refrigerator.
  • For a Southern green bean casserole twist, stir in 1/2 cup of shredded sharp cheddar cheese with the green bean mixture before baking.
  • If you want to make this recipe from scratch and skip the canned soup, combine 1/2 cup beef broth, 1/2 cup milk, 1 tablespoon cornstarch, and 1/2 teaspoon dried thyme. Heat this mixture in a saucepan until thickened before mixing with the beans.
