Ingredients

Scale

Vegetables

  • 1.5 pounds fresh green beans, trimmed

Creamy Sauce

  • 1 can (10.5 ounces) condensed cream of mushroom soup
  • 0.5 cup milk
  • 1 teaspoon soy sauce
  • 0.25 teaspoon black pepper

Topping

  • 1 can (6 ounces) French-fried onions

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it is hot and ready for baking the casserole evenly.
  2. Cook Green Beans: Boil or steam the green beans until they are tender-crisp. Once cooked, drain them thoroughly to remove excess water which could make the casserole watery.
  3. Mix Sauce: In a large bowl, combine the condensed cream of mushroom soup, milk, soy sauce, and black pepper. Stir well to create a smooth and flavorful sauce base.
  4. Combine Green Beans and Sauce: Add the cooked green beans to the sauce mixture and gently stir until the beans are evenly coated with the creamy mixture.
  5. Assemble Casserole: Pour the green bean mixture into a 2-quart baking dish, spreading it out evenly for consistent cooking.
  6. Bake First Phase: Place the baking dish in the preheated oven and bake for 20 minutes to allow flavors to meld and the casserole to heat through.
  7. Add Topping: Remove the casserole from the oven and sprinkle the French-fried onions evenly over the top to add a crunchy texture.
  8. Bake Final Phase: Return the casserole to the oven and bake for an additional 5-10 minutes, or until the fried onions are golden brown and the casserole is bubbly around the edges.

Notes

  • For a richer flavor, consider using cream of celery soup instead of cream of mushroom soup.
  • If you prefer, make your own homemade cream of mushroom soup to enhance the freshness and taste.
  • To prepare ahead, assemble the casserole without the fried onions and refrigerate. Add fried onions just before baking, and increase the baking time by a few minutes to ensure thorough heating.
