Equipment

  • 2 ½ Quart Oval Casserole Dish
  • Large Pot
  • Measuring Cups and Spoons
  • Mixing Bowls
  • Whisk
  • Large Skillet

Ingredients

  • 2 tablespoon salt for boiling
  • 2 pounds Brussels sprouts halved
  • 8 strips bacon diced small
  • 1 ½ tablespoon all-purpose flour
  • 2 cups heavy cream
  • 4 ounces white cheddar cheese grated
  • 4 ounces gruyere cheese grated
  • ½ teaspoon ground black pepper
  • ½ cup panko breadcrumbs
  • ½ cup parmigiano Reggiano grated
  • 2 tablespoon butter unsalted and melted

Instructions

  • Preheat oven to 400F and spray casserole dish with nonstick spray.
  • Prepare an ice bath for when the sprouts are done in a large bowl.
  • Bring a large pot of water to boil, add salt then steam Brussels sprouts for about 4 minutes with the heat off (note: you want them to be tender enough to pierce with a fork but not too soft).
  • Strain, then place into the ice bath to stop the cooking process. Lightly dry with paper towel and set aside.
  • Meanwhile, cook bacon over medium high heat until crispy. Using a slotted spoon, transfer to a plate with paper towel and set aside.
  • In the pan with the bacon grease, whisk in flour and cook for 2 minutes.
  • Lower the heat to medium and slowly pour heavy cream while whisking. Keep a simmer going and cook until thicken about 4-5 minutes.
  • Sprinkle in cheeses slowly, continuing to whisk well incorporated.
  • Add pepper, mix, then remove from heat.
  • Stir in Brussels sprouts and bacon until well coated, then transfer to prepared casserole dish.
  • In a small bowl mix panko and parmigiano Reggiano, then add melted butter.
  • Sprinkle over the top of the Brussels sprouts and bake for about 15 minutes, or until golden brown and the edges are bubbling.

Notes

  • Briefly steaming Brussels sprouts keeps them tender without becoming mushy.
  • Make sure sprouts are dry before mixing, excess moisture can thin the sauce.
  • Pre-shredded cheese can make the sauce grainy, freshly grated melts smoother.
  • The casserole should be bubbling around the edges with a golden top.
  • This dish is best straight from the oven when the sauce is creamy and hot.
