A rich and comforting Bacon Brussels Sprouts Gratin Recipe featuring roasted Brussels sprouts, smoky bacon, and a creamy cheese sauce.
6 Servings
Ingredients
- 1 ½ pounds Brussels sprouts halved
- 8 oz bacon cooked and crumbled
- 1 cup sharp cheddar cheese grated
- ½ cup fontina cheese grated (optional)
- ¾ cup heavy cream
- 2 tbs extra-virgin olive oil
- 1 large egg
- 1 sprig fresh rosemary finely minced
- 1 tsp garlic powder
- 1 tsp onion powder
- ½ tsp red pepper flakes optional
- Kosher salt to taste
- Freshly ground black pepper to taste
Instructions
Prepare the oven and vegetables.
- Preheat the oven to 400°F (200°C). Toss the halved Brussels sprouts with the olive oil, then season generously with salt and black pepper. Arrange the sprouts in a large baking dish. Roast for 15–20 minutes, or until partially softened and lightly browned.
Create the custard mixture.
- In a mixing bowl, whisk together the egg, heavy cream, minced rosemary, garlic powder, onion powder, and red pepper flakes, if using. Incorporate most of the cheddar and fontina cheese until evenly combined.
Assemble the gratin.
- Remove the Brussels sprouts from the oven. Stir in three-quarters of the crumbled bacon. Pour the prepared cream and cheese mixture over the sprouts and gently combine. Sprinkle the remaining bacon over the surface.
Bake.
- Reduce the oven temperature to 350°F (175°C). Return the baking dish to the oven and bake for 20–25 minutes, or until the cheese is melted, bubbling, and set around the edges.
Serve.
- Allow the gratin to rest for 5 minutes before serving warm.
