Ingredients
  

For the Base

  • 4 cups fresh green beans, trimmed and blanched Fresh gives the best texture; frozen can be used if thawed and drained.

For the Sauce

  • 1 can cream of mushroom soup (10.5 oz) Classic base; can use low-fat for a lighter version.
  • 1/2 cup milk Any type of milk; use unsweetened plant-based for dairy-free.
  • 1/2 teaspoon garlic powder Optional; fresh garlic can be substituted.
  • Salt and pepper to taste

Optional Add-ins

  • 1/2 cup sliced mushrooms Sauté for added depth, optional.
  • 1 tablespoon butter For sautéing mushrooms, optional.

To Serve / Top

  • 1 cup French fried onions Divided; use for topping and mixing.

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C). Trim the green beans and blanch them in boiling water for 2–3 minutes, then plunge into ice water to stop cooking. Drain well.
  • If using mushrooms, heat 1 tablespoon butter in a skillet over medium heat. Add the sliced mushrooms and sauté until tender, about 4–5 minutes. Remove from heat and set aside.

Combine Ingredients

  • In a large mixing bowl, whisk together the cream of mushroom soup, milk, garlic powder, salt, and pepper until smooth.
  • Add the blanched green beans and sautéed mushrooms to the sauce. Toss gently to coat.
  • Transfer the mixture to a casserole dish and spread it evenly.

Baking

  • Bake in the preheated oven for 20–25 minutes, until hot and bubbly.
  • Remove from the oven and stir in half of the French fried onions. Scatter the remaining onions on top.
  • Return the dish to the oven and bake an additional 5–7 minutes until the onions are golden brown.

Serving

  • Let the casserole rest for a few minutes before serving.

Notes

Blanch beans quickly and drain thoroughly to avoid watering down the sauce. Customize with additional seasonings or cheese for variations.
