Serves 6
Ingredients
- 2 (12 oz.) packages frozen French-cut green beans
- 8 ounces cremini mushrooms, quartered
- 3 tablespoons butter
- 1 small onion, halved and thinly sliced
- 1 tablespoon fresh parsley, chopped
- 2 tablespoons all-purpose flour
- 1/2 teaspoon lemon zest
- 1/2 teaspoon salt
- 1 pinch ground black pepper
- 1/2 cup milk
- 1 cup sour cream
- 1/2 cup shredded cheddar cheese
- 1 (2.8 oz.) can canned French-fried onions
Directions
- Preheat the oven to 350 degrees.
- Place green beans into a saucepan and fill with about 1/2 inch of water.
- Bring to a boil and steam until beans are tender but still bright green, about 5 minutes. Drain and toss with the mushrooms. Set aside.
- Melt the butter in a large skillet over medium heat. Add the onion and parsley. Cook and stir until onion is tender.
- Whisk in flour until blended, then mix in the lemon zest, salt, and pepper.
- Gradually whisk in milk, stirring constantly, so that no lumps form.
- Stir in sour cream.
- Warm over medium heat until the sauce begins to bubble. Mix in the green beans and mushrooms, stirring to coat.
- Remove from heat and toss briefly with some of the cheddar cheese and French-fried onions, saving some of each to sprinkle over the top. Spoon into a 1 1/2-quart casserole dish and top with the reserved onions and cheese.
- Bake in the preheated oven until the cheese melts, about 15 minutes.
