A comforting baked mac and cheese with crispy Brussels sprouts, all cooked on a single sheet pan for easy cleanup and maximum flavor.

I first made this for my family when we wanted homemade mac and cheese but didn't want the fuss of washing several pans. The Brussels sprouts become crispy and caramelized while soaking up the cheesy sauce, making this a favorite for both kids and adults.

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

Preparation:
Preheat the oven to 220°C (425°F). Line a large rimmed sheet pan with parchment paper or lightly grease it.
Brussels Sprouts:
Toss Brussels sprouts with olive oil, salt, and pepper. Spread evenly on half of the sheet pan.
Roasting:
Roast Brussels sprouts for 12 minutes while preparing the pasta and cheese sauce.
Pasta:
Meanwhile, bring a large pot of salted water to a boil. Cook macaroni for 2 minutes less than package directions (al dente). Drain and set aside.
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).
Mixing:
Reduce heat to low. Stir in cheddar, Gruyère, Dijon, garlic powder, smoked paprika, salt, and pepper. Mix until cheese is melted and sauce is smooth.
Assembly:
Combine drained macaroni with cheese sauce. Remove sheet pan from oven; spread mac and cheese over the other half of the pan, nestling in with the partially roasted Brussels sprouts.
Topping:
In a small bowl, mix panko, Parmesan, and melted butter. Sprinkle evenly over the macaroni.
Baking:
Return sheet pan to oven and bake for 15 – 18 minutes, until topping is golden and Brussels sprouts are crisp-tender.
