Description

This Easy Green Bean Casserole is a classic comfort food favorite, combining tender green beans with a creamy mushroom sauce and topped with crispy fried onions. Perfect for holidays or family dinners, this casserole is simple to prepare and delivers a deliciously satisfying side dish.


Ingredients

Scale

Main Ingredients

  • 4 cups canned or frozen green beans, drained (about 2 cans or 16 oz frozen)
  • 1 can (10.5 oz) condensed cream of mushroom soup
  • 1/2 cup milk
  • 1 teaspoon soy sauce (optional, for added flavor)
  • Salt and pepper, to taste
  • 1 cup crispy fried onions (plus extra for topping)


Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease an 8×8 inch baking dish or similar-sized casserole dish to prevent sticking.
  2. Mix Ingredients: In a large bowl, combine the drained green beans, condensed cream of mushroom soup, milk, and soy sauce if using. Season with salt and pepper to taste. Stir in 1 cup of crispy fried onions to incorporate crunch inside the casserole.
  3. Prepare for Baking: Pour the green bean mixture into the prepared baking dish and spread it out evenly to ensure even cooking.
  4. Bake First Stage: Place the casserole in the oven and bake for 25 minutes or until the edges are bubbly, signaling that the mixture is heated through and flavors melded.
  5. Add Topping and Bake Again: Remove the casserole briefly from the oven. Sprinkle additional crispy fried onions on top, then return to the oven and bake for an extra 5-10 minutes until the onions are golden brown and crispy on top.
  6. Cool and Serve: Allow the casserole to cool slightly after baking. Serve warm for the best flavor and texture experience.

Notes

  • Drain green beans well to prevent a watery casserole.
  • Using soy sauce is optional but adds a subtle umami flavor.
  • For a vegetarian version, ensure the mushroom soup is vegetarian-friendly.
  • This casserole can be prepared in advance and baked just before serving.
  • Leftovers can be refrigerated and reheated in the oven for best texture retention.
