Ingredients
Scale
Brussels Sprouts
- 16 ounces Brussels sprouts, cleaned, trimmed, and cut in half
Sauce
- 2 tablespoons butter
- 3 cloves garlic, minced
- ½ cup heavy cream
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
- ¼ teaspoon garlic powder
- ⅛ teaspoon nutmeg
Cheese
- ½ cup shredded parmesan cheese
- 1 cup shredded cheddar cheese
- 1 cup shredded fontina cheese
Instructions
- Preheat: Position a rack in the center of your oven and preheat it to 375ºF (190ºC) to ensure even cooking of the gratin.
- Prep: While the oven warms, clean and trim the Brussels sprouts, then cut them in half. Shred the fontina, cheddar, and parmesan cheeses and combine them in a bowl, setting aside half for later use.
- Infuse: Place an oven-proof pan such as a cast iron skillet or braiser on the stovetop over medium heat. Add the butter and minced garlic, allowing the garlic to soften and gently simmer in the butter without browning. Once fragrant, remove the pan from heat and stir in the heavy cream, kosher salt, black pepper, garlic powder, nutmeg, and half of the shredded cheese blend.
- Bake: Add the halved Brussels sprouts into the cream sauce and stir until they are well coated. Spread the sprouts in an even layer in the pan. Sprinkle the remaining cheese over the top. Transfer the pan to the preheated oven and bake for 18-25 minutes, until the cheese is melted, bubbling, and the Brussels sprouts are cooked through and tender.
- Serve: Remove the gratin from the oven and serve warm alongside your favorite protein and sides for a comforting and delicious meal.
Notes
- If you don’t have an oven-safe pan, you can prepare the sauce and Brussels sprouts on the stovetop in a regular skillet, then transfer the mixture to a baking dish before adding cheese and baking.
- For extra crispiness, you can broil the top for 1-2 minutes at the end of baking, watching closely to prevent burning.
- Make sure not to brown the garlic when infusing it in butter to avoid bitterness; soft and fragrant is ideal.
- This dish can be prepped ahead and baked just before serving to save time.
