Bacon and Brussels Sprouts

  • 6 slices bacon cut into ½-inch pieces
  • 1 large shallot sliced
  • 1 teaspoon Italian seasoning or oregano, or thyme
  • 2 tablespoon butter
  • 2 pounds Brussels Sprouts rinsed and halved
  • Salt to taste

Creamy sauce:

  • 1 ½ cup heavy cream
  • 1 cup Gruyere Cheese or white cheddar, shredded
  • 1 cup bread crumbs
  • 2 tablespoon butter cut into pieces



  • Heat 6 slices bacon, cut into ½ inch pieces, over medium-high heat in a large cast iron pan or Dutch oven. Cook, stirring frequently, until well browned, about 8 minutes. Remove from pan.


  • Add shallots and 1 teaspoon Italian seasoning and cook, stirring, until shallots are softened and fragrant, about 1 minute.

Brussels Sprouts

  • Move shallots all the way to the side (to avoid overlooking them when browning the sprouts) and add 2 tablespoon butter. Once melted, fill the pan with Brussels sprouts and cook on medium high heat until nicely browned, about 4 minutes. Now you can mix those shallots with the sprouts.

Heavy cream

  • Add heavy cream and scrape up any browned bits from the bottom of the pan. Bring to a simmer.

Final Assembly

  • Add cooked bacon to the pan. Taste and add salt and pepper to taste. Top with 1 cup Gruyere cheese, then 1 cup bread crumbs and dot with 2 tablespoon butter pieces.
  • Bake at 425 F until bubbly and golden brown, about 15 minutes.
