Crispy Parmesan-Crusted Roasted Brussels Sprouts

Preheat the oven to 425 degrees F (220 degrees C).

Stir together Parmesan cheese, butter, garlic powder, onion powder, salt, and pepper in a bowl. Scatter cheese mixture in an even layer in the center of a large nonstick rimmed baking sheet. Press Brussels sprouts, cut sides down, into cheese mixture in a single even layer about 3/4- to 1-inch apart.

Bake in the preheated oven until Brussels sprouts are tender and cheese layer is golden brown and crisp, 16 to 18 minutes (the cheese will further crisp once removed from the oven). Let stand 5 minutes; gently separate Brussels sprouts to serve. Sprinkle with lemon zest, and serve hot.
