Ingredients
•
2 (12 ounce) packages frozen French cut green beans
•
8 ounces crimini mushrooms, quartered
•
3 tablespoons butter
•
1 small onion, halved and thinly sliced
•
1 tablespoon chopped fresh parsley
•
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 4/5 ounce) can French-fried onions
Directions
1
Preheat the oven to 350 degrees F (175 degrees C).
2
Place green beans in a saucepan and fill with about 1/2 inch water; bring to a boil. Cover and steam until beans are tender but still bright green, about 5 minutes. Drain.
3
Combine drained beans in a bowl with mushrooms; toss to combine.
4
Melt butter in a large skillet over medium heat. Add onion and parsley; cook and stir until onion is tender, 5 to 7 minutes. Whisk in flour until blended, then mix in lemon zest, salt, and pepper. Gradually whisk in milk, stirring constantly, so that no lumps form.
5
Add sour cream and stir until combined. Warm over medium heat until sauce begins to bubble. Dump in green beans and mushrooms, stirring to coat.
6
Remove from the heat and toss briefly with 1/2 of the Cheddar cheese and 1/2 of the French-fried onions. Spoon into a 1 ½-quart casserole dish; top with the remaining Cheddar and onions.
7
Bake in the preheated oven until Cheddar is melted, about 15 minutes.
8
Serve and enjoy.
