Ingredients

• For the Brussels Sprouts:
• 1 ½ pounds Brussels sprouts, washed and halved
• 2 tablespoons extra-virgin olive oil
• Kosher salt, to taste
• Freshly ground black pepper, to taste
• For the Cheese Sauce:
• 1 large egg
• ¾ cup heavy cream
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 sprig fresh rosemary, minced
• ½ teaspoon red pepper flakes (optional, for a hint of heat)
• 1 cup grated sharp cheddar cheese
• ½ cup grated fontina cheese (optional, for extra creaminess)
• For the Bacon Topping:
• 6 slices bacon, cooked and crumbled

Preparation Method

Preheat the Oven:Set your oven to 400ºF (204ºC). High heat helps caramelize the Brussels sprouts and enhances their natural sweetness.

Prepare the Brussels Sprouts:Wash and thoroughly dry the Brussels sprouts. Trim the stems and cut each sprout in half lengthwise.

Season and Roast:In a large mixing bowl, toss the halved Brussels sprouts with olive oil, salt, and black pepper. Spread them in a single layer on a large baking dish to ensure even roasting. Roast in the preheated oven for 15-20 minutes, or until the edges start to caramelize.

Prepare the Cheese Mixture:In a medium bowl, whisk together the egg, heavy cream, garlic powder, onion powder, rosemary, and red pepper flakes (if using). Fold in the shredded cheddar and fontina cheese until evenly combined.

Assemble the Gratin:Sprinkle ¾ of the crumbled bacon over the partially roasted Brussels sprouts. Evenly pour the cheese and cream mixture over the sprouts and bacon, gently stirring to coat. Scatter the remaining bacon pieces on top for extra crunch and flavor.

Final Baking:Reduce the oven temperature to 350ºF (177ºC). Bake for 20-25 minutes, or until the cheese is melted, bubbly, and golden brown on top.

Serving:Allow the gratin to rest for 5 minutes before serving to help it set. Scoop out generous portions, ensuring each serving has a balance of Brussels sprouts, bacon, and creamy cheese. Garnish with a sprig of fresh rosemary for an elegant finishing touch.

Tips and Conclusion

For an extra crispy topping, broil the gratin for 2-3 minutes after baking until the top turns golden brown. You can also add toasted breadcrumbs for a bit of crunch.
