  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Cheese Sauce:

  • 2 tablespoons unsalted butter
  • 2 cloves garlic, minced

  • 1/3 cup panko breadcrumbs

Instructions

  1. Preheat the oven: Preheat the oven to 400°F.
  2. Roast Brussels sprouts: Toss Brussels sprouts with olive oil, salt, and pepper. Roast for 15 minutes until golden.
  3. Make cheese sauce: Melt butter, sauté garlic, add flour, milk, and cream. Whisk until thickened. Stir in mustard, nutmeg, and half of Gruyère.
