Ingredients
  

Main Ingredients

  • 1.5 pounds Brussels sprouts
  • 6 slices diced bacon

Sauce Ingredients

  • 2 tablespoons butter
  • 2 tablespoons all-purpose flour
  • 1 teaspoon salt
  • 0.5 teaspoon freshly ground black pepper
  • 2 cups whipping cream or half and half
  • 0.5 cup grated Parmesan cheese
  • 1 cup shredded mozzarella cheese

Instructions
 

Preparation

  • In a large pot of boiling water, blanch 1 ½ pounds of Brussels sprouts for 7 minutes. After blanching, transfer them to an ice bath to stop the cooking process, then drain and set aside.
  • In a medium saucepan, cook 6 slices of diced bacon for 4-5 minutes or until crisp. Remove the bacon and place it on a paper towel-lined plate to absorb excess grease.
  • Preheat your oven to 350 degrees Fahrenheit.

Assembly

  • Add the blanched Brussels sprouts to the bottom of a 9 x 13-inch pan or large skillet.
  • In a small saucepan, melt 2 tablespoons of butter. Add 2 tablespoons of all-purpose flour, 1 teaspoon of salt, and ½ teaspoon of freshly ground black pepper. Whisk in 2 cups of whipping cream and ½ cup of grated Parmesan cheese until the mixture starts to thicken.
  • Pour the creamy mixture over the Brussels sprouts. Top with the crispy bacon and 1 cup of shredded mozzarella cheese.

Baking

  • Bake for 20-25 minutes or until the top is golden and bubbly.

Notes

To store leftovers, let the dish cool completely and transfer it to an airtight container. Refrigerate for up to 3-5 days. Reheat in the oven or microwave until warmed through.
