  • 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

Instructions

Prep Oven and Sheet 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 preparing pasta and cheese sauce.
Cook Pasta:
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.

Melt butter over medium heat in a saucepan. 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 & Seasonings:
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.
Combine & Assemble:
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.
Make and Add Topping:
In a small bowl, mix panko, Parmesan, and melted butter. Sprinkle evenly over macaroni.
Bake:
Return sheet pan to oven and bake for 15–18 minutes, until topping is golden and Brussels sprouts are crisp-tender.
