1 pound fresh green beans, trimmed and cut into 1-inch pieces
2 tablespoons butter
1/2 cup diced onion
1/2 cup diced celery
1/2 cup sliced mushrooms
3 tablespoons all-purpose flour
1/2 teaspoon salt
1/4 teaspoon ground black pepper
1 cup chicken broth
1 cup half-and-half
1/2 cup shredded sharp cheddar cheese
1/2 cup grated Parmesan cheese
1/2 cup French-fried onions
Directions
Preheat oven to 350 degrees F (175 degrees C).
Bring a pot of salted water to a boil. Add the green beans and cook until tender, about 5 minutes. Drain and set aside.
Melt the butter in a large skillet over medium heat. Add the onion, celery, and mushrooms, and cook until softened, about 5 minutes. Add the flour, salt, and pepper, and stir to combine. Gradually add the chicken broth and half-and-half, stirring until thickened.
Remove from heat and stir in the cheddar cheese until melted. Add the cooked green beans and stir to combine.
Transfer the mixture to a 2-quart baking dish. Sprinkle with the Parmesan cheese and French-fried onions. Bake for 25 minutes, or until bubbling and golden brown.
