# Step-by-Step Instructions:
01 - Preheat oven to 425°F. Line a large rimmed sheet pan with parchment paper or lightly grease it.
02 - Toss Brussels sprouts with olive oil, kosher salt, and black pepper. Spread evenly on half of the sheet pan.
03 - Roast Brussels sprouts for 12 minutes while preparing macaroni and cheese sauce.
04 - Bring a large pot of salted water to a boil. Cook macaroni for 2 minutes less than package directions until al dente. Drain and set aside.
05 - Melt butter over medium heat in a saucepan. Whisk in flour and cook for 1 minute. Gradually add whole milk and heavy cream, whisking constantly until smooth. Simmer gently for 3 to 4 minutes until slightly thickened.
06 - Reduce heat to low. Stir in cheddar, Gruyère, Dijon mustard, garlic powder, smoked paprika, salt, and pepper. Continue stirring until cheese is fully melted and sauce is smooth.
07 - Mix drained macaroni with cheese sauce thoroughly. Remove sheet pan from oven and spread mac and cheese on the unoccupied half alongside the partially roasted Brussels sprouts.
08 - Combine panko breadcrumbs, Parmesan cheese, and melted butter in a small bowl. Sprinkle evenly over the macaroni mixture.
09 - Return sheet pan to oven and bake for 15 to 18 minutes, until topping is golden and Brussels sprouts are crisp-tender.
10 - Sprinkle chopped fresh parsley over the finished dish if desired. Serve immediately.
