# Cooking Steps:
01 - Preheat the 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 the pasta and sauce.
04 - Bring a large pot of salted water to a boil. Cook macaroni until al dente, about 2 minutes less than package instructions. Drain and set aside.
05 - In a medium saucepan over medium heat, melt butter. Whisk in flour and cook for 1 minute. Gradually whisk in milk and cream until smooth. Simmer gently, stirring constantly, until slightly thickened, about 3 to 4 minutes.
06 - Reduce heat to low. Stir in cheddar, Gruyère, Dijon mustard, garlic powder, smoked paprika, salt, and pepper. Mix until cheese melts and sauce is smooth.
07 - Mix drained macaroni into cheese sauce. Remove sheet pan from oven and spread mac and cheese on the empty half, nestling alongside the partially roasted Brussels sprouts.
08 - In a small bowl, combine panko breadcrumbs, Parmesan cheese, and melted butter. Sprinkle evenly over macaroni.
09 - Return sheet pan to oven and bake 15 to 18 minutes, until topping is golden brown and Brussels sprouts are crisp-tender.
10 - Optionally, garnish with chopped fresh parsley. Serve immediately while hot.
