Ingredients

The following ingredients have 6 Servings
  • 1 pound brussel sprouts (trimmed and sliced)
  • 1 tablespoon olive oil
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • ¼ teaspoon garlic powder
  • 1 tablespoon butter
  • ¼ cup finely chopped onions
  • 2 tablespoons all-purpose flour
  • 1 teaspoon mustard powder
  • 1 cup fat free milk
  • ½ cup grated Gruyere cheese (divided)

Instruction

  • Preheat the oven to 425°F.
  • Place brussel sprouts on an 8 x 11 rimmed baking dish, drizzle with olive oil and season with salt, pepper and garlic powder. Toss to coat evenly, and then roast until golden brown, about 20-25 minutes, tossing halfway through.
  • In a small saucepan over medium heat, melt the butter. Add the onions and cook until translucent, about 3-5 minutes. Add the flour and mustard powder and stir until the flour dissolves, about 1-2 minutes. Slowly pour the milk and stir with a wooden spoon until the sauce thickens. Add ¼ cup gruyere cheese and stir until well blended.
  • When the brussel sprouts are done roasting, pour the sauce over the brussel sprouts. Sprinkle remaining gruyere cheese on top.
  • Return the brussel sprouts to the oven and cook until the cheese is melted and bubbly, about 15 more minutes. Serve warm.
