Ingredients

• 500 grams Brussels sprouts
• 240 milliliters Heavy cream
• 150 grams Gruyère cheese, shredded
• 50 grams Parmesan cheese, grated
• 15 grams Butter
• 2 cloves Garlic, minced
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.25 teaspoon Nutmeg (optional)
• 50 grams Panko breadcrumbs
• 1 tablespoon Olive oil

Directions

Step 1

Preheat your oven to 200°C (400°F).

Step 2

Trim the Brussels sprouts by slicing off the ends and removing any outer, discolored leaves. Cut each sprout in half lengthwise.

Step 3

Bring a pot of lightly salted water to boil. Add the halved Brussels sprouts and blanch them for 3–4 minutes. Drain and set aside.

Step 4

In a medium skillet, melt the butter over medium heat. Add the minced garlic and sauté for 1 minute until fragrant, but not browned.

Step 5

Pour the heavy cream into the skillet and bring it to a gentle simmer. Stir in half the Gruyère cheese, all the Parmesan cheese, salt, black pepper, and nutmeg (if using). Mix until smooth and creamy, then remove from heat.

Step 6

In a greased 9x9 inch (or similar size) baking dish, spread the blanched Brussels sprouts evenly. Pour the cheese sauce over the top, ensuring all sprouts are well-coated.

Step 7

Sprinkle the remaining Gruyère cheese over the dish.

Step 8

In a small bowl, toss the panko breadcrumbs with the olive oil. Distribute this mixture evenly over the cheese layer for a crunchy topping.

Step 9

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

Step 10

Let the dish cool for 5 minutes before serving. Enjoy your creamy, cheesy Brussels sprouts au gratin!
