Instructions
- 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.
