Ingredients

  • 2 pounds Brussels sprouts
  • 4 slices bacon, diced
  • 3 cloves garlic, minced
  • 1/4 cup shallots, diced
  • 2 tablespoons all-purpose flour
  • 3/4 cup whole milk, plus more, to taste
  • 1/4 cup heavy cream
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon ground nutmeg
  • kosher salt, to taste
  • freshly ground black pepper, to taste
  • 1 1/4 cups Gruyère cheese, shredded, divided

Directions

Step 1 -Preheat the oven to 400 degrees F.

Step 2 -In a large pot of boiling salted water, blanch the sprouts until they are crisp-tender, about 3-5 minutes.

Step 3 -Drain the sprouts well and place them in a bowl of ice water until they are cool.

Step 4 -Drain the cooled sprouts well.

Step 5 -In a large oven-proof skillet over the medium-high heat, add the bacon slices and cook until they are brown and crispy, about 6-8 minutes.

Step 6 -Reserve 1 tablespoon of the bacon grease in the skillet and discard the rest. Transfer the bacon to a paper-towel-lined plate.

Step 7 -Add the garlic and the shallots to the bacon grease and cook, stirring frequently, until the garlic is fragrant, about 2 minutes.

Step 8 -Whisk the flour into the garlic mixture until it is lightly browned, about 1 minute.

Step 9 -Gradually whisk the milk, the heavy cream, the thyme, and the nutmeg into the flour mixture and cook, whisking constantly, until it is incorporated and thickens slightly, about 1-2 minutes. If the mixture is too thick, add more of the milk as needed.

Step 10 -Season the sauce with the salt and the pepper.

Step 11 -Stir the cooled sprouts, the cooked bacon, and 1 cup of the cheese into the sauce until the cheese has melted, about 1-2 minutes.

Step 12 -Sprinkle the sprout mixture with the remaining cheese.

Step 13 -Bake the sprout mixture until it is golden-brown and bubbly, about 20-25 minutes.

Step 14 -Serve immediately.
