Instructions

1. In a large skillet over medium heat, heat olive oil. Add the bacon and cook, stirring occasionally, until brown and crispy. Remove bacon with a slotted spoon and transfer to a paper-towel lined plate.
2. Add the brussels sprouts to the same pan with the bacon fat and cook, stirring occasionally, until brussels sprouts start to brown and turn golden, about 7-8 minutes. Add the shallots and stir for another 2 minutes, until shallots begin to soften. Add the wine and cook for another couple minutes until reduced by half. Add the broth, salt, and pepper and bring to a boil. Continue to cook until liquid is reduced by half and brussels sprouts are tender, about 5 minutes.
3. Preheat oven to 375. Lightly oil a 2-quart baking dish. Using a slotted spoon, transfer brussels sprouts to prepared dish. Sprinkle half of the gruyere on top. Boil the remaining cooking liquid until it’s reduced to about 2 tablespoons. Lower heat to medium, add the cream and milk, and continue to cook to reduce by half, about 10 minutes. Season to taste with additional salt and pepper.
4. Pour cream mixture over brussels sprouts and gruyere. Sprinkle with crisped bacon and then top with remaining gruyere. Bake until bubbly and top starts to turn golden brown, about 20 minutes. Serve immediately.
