Homemade Green Bean Casserole Recipe from Scratch

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
• 0.5 teaspoon lemon zest
• 0.5 teaspoon salt
• 1 pinch ground black pepper
• 0.5 cup milk
• 1 cup sour cream
• 0.5 cup shredded Cheddar cheese
• 1 (2.8 ounce) can French-fried onions

Instructions

1. Preheat your oven to 350 degrees F (175 degrees C).
2. In a saucepan, place green beans and add about 1/2 inch of water; bring to a boil. Cover and steam until the beans are tender yet vibrant green, approximately 5 minutes. Drain thoroughly.
3. In a bowl, combine the drained green beans with the mushrooms; toss gently to mix.
4. Melt butter in a large skillet over medium heat. Add onion and parsley; cook, stirring occasionally, until the onion softens, about 5 to 7 minutes. Whisk in flour until fully incorporated, then mix in lemon zest, salt, and pepper. Gradually whisk in milk, stirring continuously to prevent lumps.
5. Incorporate sour cream and stir until well combined. Warm over medium heat until the sauce starts to bubble gently. Add the green beans and mushrooms, stirring to ensure they are evenly coated.
6. Remove from heat and gently toss with half of the Cheddar cheese and half of the French-fried onions. Transfer to a 1 ½-quart casserole dish; sprinkle the remaining Cheddar and onions on top.
7. Bake in the preheated oven until the Cheddar cheese is melted and bubbly, about 15 minutes.
8. Serve immediately and enjoy your delicious homemade green bean casserole.
