Ingredients

  • Pasta: 340 g (12 oz) elbow macaroni
  • Vegetables: 350 g (12 oz) Brussels sprouts, trimmed and halved, 2 tbsp olive oil, 1/2 tsp kosher salt, 1/4 tsp black pepper
  • Cheese Sauce: 3 tbsp unsalted butter, 3 tbsp all-purpose flour, 500 ml (2 cups) whole milk, 120 ml (1/2 cup) heavy cream, 180 g (2 cups) shredded sharp cheddar cheese, 60 g (1/2 cup) shredded Gruyère cheese, 1/2 tsp Dijon mustard, 1/4 tsp garlic powder, 1/4 tsp smoked paprika, salt and pepper to taste
  • Topping: 60 g (1/2 cup) panko breadcrumbs, 2 tbsp grated Parmesan cheese, 1 tbsp melted butter, 1 tbsp chopped fresh parsley (optional)

Instructions

Prep Oven and Pan:
Preheat the oven to 220°C (425°F). Line a large rimmed sheet pan with parchment paper or lightly grease it.
Roast Brussels Sprouts:
Toss Brussels sprouts with olive oil, salt, and pepper. Spread evenly on half of the sheet pan. Roast for 12 minutes while you prepare the pasta and cheese sauce.
Cook Pasta:
Bring a large pot of salted water to a boil. Cook macaroni until al dente (2 minutes less than package directions). Drain and set aside.
Prepare Cheese Sauce:
In a saucepan, melt butter over medium heat. Whisk in flour and cook for 1 minute. Gradually whisk in milk and cream until smooth. Bring to a gentle simmer, stirring constantly, until slightly thickened (about 3–4 minutes).
Add Cheese and Seasonings:
Reduce heat to low. Stir in cheddar, Gruyère, Dijon mustard, garlic powder, smoked paprika, salt, and pepper until cheese is melted and sauce is smooth.
Mix Pasta and Sauce:
Combine drained macaroni with the cheese sauce.
Arrange on Sheet Pan:
Remove sheet pan from oven. Spread mac and cheese over the other half of the pan, nestling with the partially roasted Brussels sprouts.
Prepare Topping:
In a bowl, mix panko, Parmesan, and melted butter. Sprinkle over the macaroni.
Bake:
Return sheet pan to oven and bake for 15–18 minutes until topping is golden and Brussels sprouts are crisp-tender.
Serve:
Garnish with chopped parsley if desired. Serve hot.

Common Questions

How do I ensure the Brussels sprouts roast evenly?
