Mix Ingredients: In a large bowl, combine the steamed green beans, sautéed mushrooms, 1 can of cream of mushroom soup, ½ cup of milk, garlic powder, salt, and pepper. Mix well until all the ingredients are thoroughly combined, ensuring every bite is flavorful.
Transfer to Baking Dish: Pour the delicious mixture into a greased baking dish, spreading it evenly. Top generously with French fried onions for that irresistible crunch.
Bake: Place the casserole in the preheated oven and bake for 25-30 minutes. You’ll know it’s ready when the edges are bubbly and the top has turned a lovely golden brown.
