Ingredients

  • 6 slices bacon, preferably thick cut
  • 30 ounces (~8 cups) brussels sprouts, roughly chopped/shredded*
  • 2 cloves garlic, minced
  • 1/2 tsp salt
  • 1 1/2 cups Gruyere cheese, shredded
  • 1 1/2 cups heavy cream
  • 3/4 cup bread crumbs
  • 2 tbsp butter, melted

Instructions

  • Preheat the oven to 400 degrees F.
  • In a large skillet, cook the bacon over medium-high heat until crispy.
  • Remove the bacon from the pan, leaving the grease.
  • Add the brussels sprouts and cook until slightly softened, about 5 minutes.
  • Add the garlic and salt and cook another minute.
  • Chop the cooked bacon and toss it with the brussels sprouts, along with 1 cup of Gruyere cheese.
  • Transfer the mixture to a greased 9x13” baking dish.
  • Drizzle with the heavy cream and then top with remaining cheese.
  • In a small bowl, stir together the melted butter and breadcrumbs.
  • Sprinkle the breadcrumbs over the gratin.
  • Note: at this point, you can cover with plastic wrap and refrigerate until ready to bake, up to one day in advance. 
  • Bake the gratin in the preheated oven for 20-25 minutes, until the breadcrumbs are golden brown.  If you are baking this after being in the refrigerator, expect to add about 5-10 minutes to the baking time. 

Notes

*I quartered half of the brussels sprouts and shredded the other half
