Green Bean Casserole

Instructions

1. 1

   Preheat oven to 350°F (175°C). Trim the green beans and cut them into 2-inch pieces.

2. 2

   Bring a large pot of salted water to a boil. Blanch the green beans for 5 minutes until tender-crisp. Drain and set aside.

3. 3

   In a large skillet, melt butter over medium heat. Add mushrooms and cook for 5 minutes until golden.

4. 4

   Add diced onion and minced garlic to the skillet. Sauté for 3-4 minutes until onion is translucent.

5. 5

   Sprinkle flour over the vegetables and stir constantly for 1 minute to cook the flour.

6. 6

   Gradually pour in chicken broth while stirring to prevent lumps. Bring to a simmer and cook until thickened, about 3 minutes.

7. 7

   Remove from heat and stir in heavy cream, sour cream, salt, and pepper until well combined.

8. 8

   Add the blanched green beans to the cream sauce and mix gently to coat evenly.

9. 9

   Transfer the mixture to a greased 9x13 inch baking dish, spreading it evenly.

10. 10

    Sprinkle half of the fried onions evenly over the top of the casserole.

11. 11

    Bake for 25 minutes until bubbly around the edges.

12. 12

    Remove from oven, top with remaining fried onions, and bake for 5 more minutes until onions are golden.

13. 13

    Let rest for 5 minutes before serving to allow the sauce to set slightly.
