How to Make Baked Brussels Sprouts Au Gratin

  1. Preheat oven to 325°F (160°C).
  2. Trim the ends and peel off any loose outer leaves from 1.5 pounds of Brussels sprouts. Cut an 'X' into the bottom of each sprout to ensure even cooking.
  3. Boil Brussels sprouts in 4 cups of water for 10 minutes, or until tender-crisp. Drain, reserving 1 cup of the hot cooking liquid.
  4. Melt 2 tablespoons of butter in a medium skillet over medium heat. Add 1/4 cup chopped green onions and sauté for 3 minutes until softened.
  5. Stir in 2 tablespoons of all-purpose flour and cook for 1 minute, stirring constantly. Add 4 ounces of cooked and crumbled bacon, 2 cloves of minced garlic, and 1/4 cup chopped fresh parsley. Cook for another 2 minutes.
  6. Gradually whisk in the reserved 1 cup of hot cooking liquid. Add 1/2 teaspoon of salt and 1/4 teaspoon of black pepper. Bring to a simmer, stirring constantly until the sauce has thickened to the consistency of heavy cream (about 2-3 minutes).
  7. Transfer the cooked Brussels sprouts to a buttered 9x13 inch casserole dish.
  8. Pour the creamy sauce over the sprouts. Top with 1 cup of shredded Gruyere cheese (or your favorite cheese) and 1/2 cup of breadcrumbs.
  9. Bake for 30-35 minutes, or until the top is golden brown and bubbly.
