Ingredients

  • 4 Tablespoons unsalted butter divided
  • 1 pound fresh brussel sprouts stems trimmed, cut in half lengthwise
  • 2 cloves garlic minced
  • ½ teaspoon kosher salt
  • ¼ teaspoon black pepper
  • 2 Tablespoons all-purpose flour
  • 1 ½ cups heavy cream
  • 1 ½ cups shredded mozzarella cheese divided
  • 1 Tablespoons fresh parsley fine chop, garnish, optional

Instructions

  • Preheat the oven to 375 degrees F. Spray a 9-inch round or square baking dish with non-stick cooking spray, set aside.
  • Place two tablespoons of the butter into a large skillet over medium-heat. Add the brussel sprouts and sear, tossing occasionally, for about 5 minutes. We are only looking for a light char, not cooking all the way through.
  • Place the brussel sprouts into the baking dish, set aside.
  • Add the remaining butter to the skillet over medium-low heat, once melted, add the garlic and cook until fragrant, stirring constantly, 30 seconds.
  • Add the salt, pepper, and flour to the skillet, whisk to combine, cook for 2 minutes. Slowly pour in the heavy cream, whisking constantly to avoid lumps. Cook until thickened, about 1 minute.
  • Take off the heat and add ½ cup of the cheese, whisk in to combine and melt in the sauce.
  • Pour the sauce on top of the brussel sprouts.
  • Top with the remaining cheese.
  • Bake for 25-30 minutes until bubbly and the cheese is golden brown on top. Garnish with optional parsley, serve.

Notes

  1. You can easily double this recipe to serve large crowds.
  2. This can be frozen, see my tips above.
  3. Add some of your other favorite add ins to this, bacon would be a good one and we add it a lot to this dish.
  4. Switch up your cheese for a different flavor.
  5. If you want you can also swap out heavy cream for half and half or milk.
  6. Make sure that you are using fresh brussel sprouts and not frozen.
