Ingredients

• 4 cups broccoli florets
• 1 medium onion
• 3 tablespoons butter
• 2 tablespoons all-purpose flour
• 1.5 cups milk
• 1 cup cheddar cheese, shredded
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper
• 0.5 cup breadcrumbs
• 1 tablespoon olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x9-inch baking dish and set it aside.

Step 2

Bring a large pot of water to a boil and blanch the broccoli florets for 2-3 minutes, until they are bright green and slightly tender. Drain and set aside.

Step 3

Peel and finely chop the onion.

Step 4

In a large skillet, heat 2 tablespoons of butter over medium heat. Add the chopped onion and sauté for 4-5 minutes, until softened and translucent.

Step 5

Sprinkle the flour over the onions and stir to coat evenly. Cook for 1 minute to remove the raw flour taste.

Step 6

Gradually whisk in the milk, stirring constantly to avoid lumps. Cook for 3-4 minutes until the sauce thickens.

Step 7

Reduce the heat to low and stir in the shredded cheddar cheese, salt, and black pepper. Mix until the cheese is melted and the sauce is smooth.

Step 8

Fold the blanched broccoli into the cheese sauce, making sure it is evenly coated. Pour the mixture into the prepared baking dish and spread it out evenly.

Step 9

In a small bowl, mix the breadcrumbs with 1 tablespoon of melted butter or olive oil until evenly coated.

Step 10

Sprinkle the breadcrumb mixture evenly over the top of the casserole.

Step 11

Bake in the preheated oven for 20-25 minutes, until the top is golden brown and the casserole is bubbly.

Step 12

Remove from the oven and let it sit for 5 minutes before serving. Enjoy your broccoli onion casserole!
