Ingredients
- 1 1/2 pounds Brussels sprouts, halved
- 8 oz. bacon, cooked and crumbled
- 1 cup sharp cheddar cheese, grated
- 1/2 cup fontina cheese, grated (optional)
- 3/4 cup heavy cream
- 2 tablespoons extra-virgin olive oil
- 1 egg
- 1 sprig rosemary, minced
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon red pepper flakes (optional)
- Kosher salt and freshly ground pepper, to taste
Instructions
Step 1: Preheat the Oven
Set your oven to 400°F to start the roasting process for the Brussels sprouts.
Step 2: Prepare the Brussels Sprouts
In a large bowl, toss the halved Brussels sprouts with 2 tablespoons of extra-virgin olive oil. Season generously with kosher salt and freshly ground pepper to taste. Spread the Brussels sprouts in a large baking dish and roast them in the preheated oven for 15-20 minutes, or until they are semi-softened and starting to brown.
Step 3: Prepare the Cheese Mixture
While the Brussels sprouts are roasting, whisk together 3/4 cup of heavy cream, 1 egg, 1 minced sprig of rosemary, 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and 1/2 teaspoon of red pepper flakes (if using) in a large bowl. Stir in the grated sharp cheddar cheese and fontina cheese (if using).
Step 4: Combine and Bake
Once the Brussels sprouts are semi-softened, remove the baking dish from the oven. Add 3/4 of the cooked and crumbled bacon to the Brussels sprouts. Pour the cheese mixture over the top and stir everything together to ensure the Brussels sprouts are well coated. Sprinkle the remaining bacon on top.
Step 5: Final Baking
Reduce the oven temperature to 350°F. Return the baking dish to the oven and bake for an additional 20-25 minutes, or until the cheese is bubbly and just set.
Step 6: Serve
Remove the gratin from the oven and let it cool for 5 minutes before serving. This allows the dish to set slightly and makes it easier to serve.
