Elevate humble Brussels sprouts into a luxurious side dish with this creamy, cheesy au gratin. Each tender sprout bathes in a velvety sauce enriched with three kinds of cheese and subtle warming spices. This comforting dish transforms the often-overlooked vegetable into the star of your holiday table or any special dinner.
The first time I served this at Thanksgiving, even the most devoted Brussels sprouts critics came back for seconds. The combination of creamy sauce and perfectly cooked sprouts creates a dish that's both sophisticated and deeply satisfying.
Essential Ingredients
- Fresh Brussels Sprouts: Ensure the best texture with a balance of tenderness and crispness.
- Unsalted Butter: Forms a rich, flavorful base for the sauce.
- Fresh Garlic: Infuses deep, aromatic complexity into the dish.
- Heavy Cream: Adds luxurious richness and a velvety texture.
- Sharp Cheddar: Provides bold, tangy flavor that enhances the creamy sauce.
- Aged Parmesan: Contributes a nutty, savory depth.
- Fontina: Melts smoothly, adding a creamy consistency.
- Fresh Nutmeg: Brings warmth and subtle spice to balance the flavors.
- Garlic Powder: Enhances the depth of flavor with an extra savory note.
- Kosher Salt: Ensures even seasoning throughout the dish.
- Black Pepper: Adds a touch of subtle heat for balance.
- Cast Iron Skillet: Delivers the best texture and even browning.
- Fresh Parsley: Brightens the dish with a fresh, herbaceous finish.
- Quality Olive Oil: Used for a flavorful finishing touch.
Creating Your Dish
- Preparing the Sprouts:
- Trim the stem ends carefully, removing any discolored outer leaves. Cut larger sprouts in half through the stem, ensuring even cooking and maximum sauce coverage.
- Building the Sauce Base:
- Melt butter until foamy, then add minced garlic, watching carefully to prevent burning. The garlic should become fragrant without taking on any color.
- Creating the Cream Sauce:
- Add heavy cream slowly, stirring constantly to create a smooth base. Season with spices, letting them bloom in the warm cream to release their flavors.
- Incorporating the Cheese:
- Add cheese gradually, stirring until each addition melts completely before adding more. This creates the smoothest possible sauce.

Growing up, my grandmother's secret to perfect au gratin was always freshly grated cheese. She insisted pre-shredded cheese never melts as beautifully, and after years of making this dish, I couldn't agree more.
Perfect Pairings
Transform this side dish into a memorable part of any meal by serving it alongside herb-roasted chicken or grilled steak. For holiday dinners, it pairs beautifully with roast turkey or glazed ham. Add crusty bread for soaking up the extra sauce, or serve with roasted potatoes for an extra-indulgent feast.
Creative Variations
Adapt this versatile dish to suit different tastes and occasions. Add crispy bacon for smoky depth. Create a breadcrumb topping with herbs and parmesan for extra crunch. Make it extra decadent with a blend of wild mushrooms, or spice it up with red pepper flakes.
Keeping Fresh
Store leftovers in an airtight container for up to three days. Reheat gently in the oven to maintain the creamy texture and prevent the sauce from breaking. For make-ahead preparation, assemble everything except the final cheese topping and refrigerate for up to 24 hours.
Simple Success
The key to perfect Brussels sprouts au gratin lies in proper preparation. Don't rush the sauce-making process, and give the dish time to develop that golden-brown crust in the oven.
Texture Tips
For the best texture, avoid overcooking the Brussels sprouts. They should be tender but still hold their shape, allowing them to soak up the creamy sauce while maintaining their structure.
