Ingredients
- 1 pound Brussel sprouts trimmed and cut in half
- 1 tablespoon olive oil
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon garlic powder
- 1 tablespoon butter
- ¼ cup onions finely chopped
- 2 tablespoons all-purpose flour
- 1 teaspoon mustard powder
- 1 cup fat free milk
- ½ cup gruyere cheese grated and divided
Instructions
- 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.

- Instead of regular milk, you can use any unsweetened plant-based milk.
- Instead of gruyere cheese, you can use shredded cheddar cheese or another one you like.
- To make this gluten-free, use an all-purpose gluten-free flour mix. You can also substitute with almond flour.
