Green Bean and Cheddar Casserole

Ingredients

Fresh green beans

1 pound, trimmed and cut into 2-inch pieces

Unsalted butter

2 tablespoons

Onion

1 medium, diced

All-purpose flour

2 tablespoons

Milk

1 cup

Shredded cheddar cheese

2 cups

Salt

1 teaspoon, or to taste

Black pepper

1/2 teaspoon, or to taste

Breadcrumbs

1 cup, for topping

Instructions

1. Preheat the oven to 350°F (175°C).
2. Bring a large pot of salted water to a boil. Add the trimmed green beans and cook for 5 minutes, or until they are crisp-tender. Drain and set aside.
3. In a large skillet, melt the unsalted butter over medium heat. Add the diced onion and cook until softened, about 5 minutes.
4. Stir in the all-purpose flour and cook for 1 minute, stirring constantly to form a roux.
5. Gradually whisk in the milk and continue to cook, stirring frequently, until the mixture thickens, about 3-4 minutes.
6. Remove the skillet from heat and stir in the shredded cheddar cheese until fully melted and smooth. Season the cheese sauce with salt and pepper to taste.
7. Add the cooked green beans to the cheese sauce and gently toss to coat the beans evenly.
8. Transfer the green bean and cheese mixture to a greased casserole dish and sprinkle the breadcrumbs evenly over the top.
9. Bake in the preheated oven for 20-25 minutes, or until the casserole is hot and bubbly, and the breadcrumbs are golden brown.
10. Serve hot and enjoy this comforting classic!
