Brussel Sprout Casserole Recipe

Ingredients

• 1 pound brussel sprouts (trimmed and halved)
• 1 tablespoon olive oil
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ¼ teaspoon garlic powder
• 1 tablespoon unsalted butter
• ½ small onion (minced)
• 1 tablespoon all-purpose flour
• 1 teaspoon mustard powder
• 1 cup whole milk
• ½ cup parmesan cheese (divided)

Steps

1. 1

   Preheat the oven to 425°F.

2. 2

   Place brussel sprouts in a 8 x 11 casserole dish, drizzle with olive oil and season with salt, pepper, and garlic powder. Toss to coat evenly, and then bake until tender, about 10-15 minutes, depending on the size of your brussels, tossing halfway through.

3. 3

   In a small saucepan over medium heat, melt the butter. Add the onions and cook until translucent, about 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. Turn off the heat, add ¼ cup parmesan cheese and stir until well blended.

4. 4

   When the brussel sprouts are done roasting, pour the sauce over the brussel sprouts. Sprinkle the remaining parmesan cheese on top.

5. 5

   Return the brussel sprouts to the oven and cook until the cheese is melted and bubbly, 10- 15 more minutes. Serve immediately.
