Instructions

Preheat Your Equipment: Start by preheating your oven to 375°F (190°C). This ensures the gratin gets that irresistible golden top.

Prepare Your Cooking Vessel: Lightly grease a baking dish or gratin pan with butter or nonstick spray.

Assemble the Dish: Transfer the Brussels sprout mixture to the dish. Sprinkle generously with Gruyère (or Cheddar) and Parmesan.

Cook to Perfection: Bake uncovered for 20–25 minutes, or until bubbly and golden on top.

Finishing Touches: Let cool for 5–10 minutes after baking the sauce will thicken and flavors will settle.

Serve and Enjoy: Dig in while warm! It’s rich, savory, and sure to disappear fast.
