Ingredients
- 1 pound fresh green beans, trimmed and cut into 1-inch pieces
- 2 tablespoons butter
- 1 medium onion, chopped
- 2 cups mixed mushrooms (button, cremini, shiitake), sliced
- 1 cup cream of mushroom sauce (homemade or store-bought)
- 1 teaspoon black pepper
- 1/2 teaspoon salt
- 1 1/2 cups french-fried onions
- 1 cup shredded cheddar cheese (optional)

Instructions
- Step 1: Prepare the Green Beans Bring a large pot of salted water to a boil. Blanch the green beans for 5 minutes, then drain and set aside.
- Step 2: Sauté the Mushrooms and Onions In a large skillet, melt 1 tablespoon of butter over medium heat. Add the chopped onion and cook until translucent, about 3-4 minutes. Add the sliced mushrooms and cook until they release their liquid and start to brown, about 5 minutes.
- Step 3: Make the Cream of Mushroom Sauce In a medium saucepan, combine the cream of mushroom soup, 1/2 cup of milk, and 1/2 teaspoon of black pepper. Bring the mixture to a simmer over medium heat, whisking constantly. Reduce the heat to low and let it simmer for 2-3 minutes, or until the sauce has thickened slightly.
- Step 4: Assemble the Casserole In a 9x13 inch baking dish, arrange the blanched green beans in an even layer. Pour the cream of mushroom sauce over the green beans, followed by the sautéed mushroom and onion mixture. Sprinkle the french-fried onions evenly over the top of the casserole.
- Step 5: Bake the Casserole Preheat your oven to 375°F (190°C). Bake the casserole for 25-30 minutes, or until the onions are golden brown and the casserole is hot and bubbly.
