  • 2 pounds Brussels sprouts, quartered
  • 2 tablespoons butter, melted
  • 3/4 teaspoon salt
  • 1/8 teaspoon pepper
  • 1 large onion, chopped
  • 3 tablespoons butter
  • 3 tablespoons all-purpose flour
  • 1 cup whole milk
  • 1 cup heavy whipping cream
  • 1/8 teaspoon white pepper
  • Dash ground nutmeg
  • 1/2 cup shredded Gruyere cheese
  • 1/4 cup grated Parmesan cheese


  1. Preheat oven to 425°. In a large bowl, combine the Brussels sprouts, butter, salt and pepper; toss to coat. Transfer to a greased 13x9-in. baking dish. Bake, uncovered, for 25-30 minutes or until Brussels sprouts are tender, stirring occasionally.
  2. Meanwhile, for the sauce, in a large skillet, saute onion in butter until tender. Stir in flour until blended; gradually add milk and cream. Bring to a boil; cook and stir for 2 minutes or until thickened. Stir in pepper and nutmeg; pour sauce over Brussels sprouts. Sprinkle with cheeses. Reduce heat to 350°. Bake, uncovered, for 10-15 minutes or until heated through and cheeses are melted.
