Equipment

Ingredients

  • 1 pound brussels sprouts
  • 1-2 tablespoons olive oil
  • 1/2 teaspoon kosher salt
  • freshly ground pepper to taste
  • 2 tablespoons butter
  • 1 large shallot minced
  • 1 teaspoon about 1 large clove garlic, minced
  • 1 tablespoon flour
  • 1 1/2 cups milk
  • 5 ounces gruyere grated and divided

Instructions

  • Preheat oven to 400 degrees F.
  • Cut each sprout in half and remove any outer leaves that are dirty. In a large bowl, toss the sprouts in the olive oil until lightly coated and then spread in a single layer in a baking dish.
  • Roast sprouts in preheated oven for 30-40 minutes, flipping once half way through cooking time, until golden brown. About five minutes before sprouts have finished cooking, prepare cheese sauce.
  • In medium sauce pan over medium high heat, melt butter. Add shallot and cook for 3-4 minutes until fragrant. Add garlic and cook another minute until golden brown. Sprinkle flour over mixture, stir well, and allow to cook for a few minutes to develop a roux.
  • Add milk and whisk mixture constantly while heating. Allow mixture to heat and thicken. As soon as it does, remove from heat and stir in half of the cheese.
  • Transfer sprouts to a 9 inch square baking dish and cover with cheese sauce. Top with remaining cheese and return to oven until cheese has fully melted, about 5 minutes. Add additional salt and pepper, if desired. Serve hot.
