Ingredients

• 1 pound Brussels sprouts
• 3 tablespoons Unsalted butter
• 2 tablespoons All-purpose flour
• 1.5 cups Whole milk
• 0.5 cups Heavy cream
• 1 cup Gruyère cheese, shredded
• 0.5 cups Parmesan cheese, grated
• 0.5 teaspoons Garlic powder
• 1 teaspoons Salt
• 0.5 teaspoons Black pepper
• 0.5 cups Panko breadcrumbs
• 1 tablespoon Olive oil
• 1 tablespoon Fresh parsley, chopped (optional)

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 2

Trim the ends of the Brussels sprouts and remove any yellow or damaged leaves. Cut larger sprouts in half to ensure even cooking.

Step 3

Bring a large pot of salted water to a boil. Add the Brussels sprouts and blanch for 3-4 minutes until they begin to soften. Drain and set aside.

Step 4

In a medium saucepan, melt 2 tablespoons of butter over medium heat. Whisk in the flour and cook for 1-2 minutes to form a roux.

Step 5

Slowly pour in the milk and heavy cream while whisking continuously to prevent lumps. Cook for 3-4 minutes until the sauce thickens.

Step 6

Remove the saucepan from the heat and stir in the Gruyère and Parmesan cheeses, garlic powder, salt, and black pepper until smooth and creamy.

Step 7

Place the blanched Brussels sprouts into a greased 9x9-inch casserole dish. Pour the cheese sauce evenly over the sprouts, ensuring they are fully coated.

Step 8

In a small bowl, mix the panko breadcrumbs with 1 tablespoon of melted butter and olive oil. Sprinkle the breadcrumb mixture evenly over the top of the casserole.

Step 9

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

Step 10

Remove from the oven and let cool for 5 minutes before serving. Garnish with fresh parsley if desired.
