Ingredients
Scale
Brussels Sprouts
- 16 ounces Brussels sprouts, cleaned, trimmed, and cut in half
Sauce and Cheese
- 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
- ½ cup shredded Parmesan cheese
- 1 cup shredded cheddar cheese
- 1 cup shredded fontina cheese
Instructions
- Preheat: Position a rack in the center of the oven and preheat it to 375ºF (190ºC) to ensure even baking of the gratin.
- Prep: While the oven is heating, clean and trim the Brussels sprouts, cutting them in half for even cooking. Shred the fontina, cheddar, and Parmesan cheeses then combine them in a bowl and set aside.
- Infuse: Heat an oven-proof pan, like a cast iron skillet or braiser, over medium heat. Add the butter and minced garlic, allowing the garlic to gently soften and infuse its flavor into the melting butter. Be careful not to brown the garlic; it should just begin to simmer. Once infused, remove the pan from heat and stir in the heavy cream, kosher salt, black pepper, garlic powder, and nutmeg. Mix in half of the shredded cheese blend until incorporated.
- Bake: Add the halved Brussels sprouts to the pan, stirring them into the creamy sauce to coat evenly. Spread the mixture in a single layer and sprinkle the remaining cheese over the top. Transfer the pan to the preheated oven and bake for 18-25 minutes, or until the cheese is melted, bubbly, and the Brussels sprouts are tender when pierced with a fork. Serve warm alongside your favorite protein and sides.
Notes
- If you don’t have a stove-to-oven safe pan, you can prepare the cream sauce in a saucepan and then transfer everything to a baking dish for the oven step.
- Ensure the garlic does not brown in the butter as it can become bitter and alter the flavor profile.
- For a crispier top, broil for 1-2 minutes after baking but watch closely to prevent burning.
