Follow The Directions

01

Step

Preheat: Preheat oven to 350 degrees F (175 degrees C).

02

Step

Prepare Dish: Spray a shallow 1 1/2-quart casserole dish with nonstick spray.

03

Step

Cook Green Beans: Place beans in a large pot and halfway cover with salted water; bring to a boil. Cook until tender, 4 to 6 minutes. Drain and set aside.

04

Step

Sauté Onion: Melt butter in a skillet over medium heat. Add onion and cook until tender, 5 to 7 minutes.

05

Step

Create Sauce: Blend in flour, salt, and pepper. Stir in sour cream, stirring constantly, cooking until smooth and thickened.

06

Step

Combine: Mix in cooked beans, then pour into the prepared casserole. Cover and refrigerate until ready to bake.

07

Step

Add Cheese: Remove casserole from the refrigerator and sprinkle Cheddar cheese over top.

08

Step

Bake: Bake in the preheated oven until bubbly, 15 to 20 minutes. Serve warm.

For a richer flavor, consider using Gruyere cheese instead of Cheddar.
This casserole can be assembled up to 24 hours in advance. Just be sure to cover it tightly and refrigerate.
If you are making this for a large group, double or triple the recipe, using a larger casserole dish.
Adjust the amount of pepper to your liking. A pinch of red pepper flakes can also add a nice touch of heat.
