Ingredients

• 900 grams Brussels sprouts
• 3 tablespoons Unsalted butter
• 2 tablespoons All-purpose flour
• 3 cloves Garlic
• 480 milliliters Whole milk
• 120 milliliters Heavy cream
• 120 grams Gruyère cheese, shredded
• 60 grams Parmesan cheese, grated
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.25 teaspoon Nutmeg (optional)
• 60 grams Panko breadcrumbs
• 1 tablespoon Olive oil

Directions

Step 1

Preheat your oven to 200°C (400°F). Lightly grease a 9x13-inch baking dish and set it aside.

Step 2

Trim the ends of the Brussels sprouts and cut them in half lengthwise. Bring a large pot of salted water to a boil and blanch the Brussels sprouts for 4-5 minutes, until tender but still vibrant. Drain and set aside.

Step 3

In a large skillet, melt the butter over medium heat. Add the minced garlic and cook for 1 minute, until fragrant.

Step 4

Whisk in the flour to create a roux, stirring constantly for 1-2 minutes, until lightly golden.

Step 5

Gradually whisk in the milk and heavy cream, continuing to stir until the mixture thickens, about 3-4 minutes.

Step 6

Lower the heat and stir in the Gruyère and Parmesan cheeses until melted and smooth. Season with salt, black pepper, and nutmeg (if using).

Step 7

Add the blanched Brussels sprouts to the cheese sauce and toss to coat evenly. Transfer the mixture to the prepared baking dish and spread it out evenly.

Step 8

In a small bowl, mix the panko breadcrumbs with olive oil. Sprinkle the breadcrumb mixture evenly over the top of the gratin.

Step 9

Bake in the preheated oven for 20-25 minutes, or until the topping is golden and crispy.

Step 10

Remove the gratin from the oven and let it cool for a few minutes before serving. Enjoy your creamy, cheesy Brussels Sprouts Gratin!
