Creating Garlic Parmesan Crusted Halibut goes smoothly if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 425°F (220°C).
2. Prepare Baking Sheet: Line a baking sheet with parchment paper or lightly grease it with cooking spray.
3. Season Halibut: Pat each halibut fillet dry with paper towels. Season both sides with salt and pepper to taste.
4. Make the Topping: In a bowl, combine the grated Parmesan cheese, breadcrumbs, minced garlic, chopped parsley, olive oil, and lemon zest. Mix until well combined.
5. Coat the Fillets: Place the seasoned halibut fillets on the prepared baking sheet. Press the Parmesan mixture onto the top of each fillet, ensuring an even coating.
6. Bake: Put the baking sheet in the preheated oven and bake for 15-20 minutes, or until the halibut is opaque and flakes easily with a fork.
7. Broil for Crispiness (Optional): If a crispier crust is desired, switch the oven to broil for an additional 1-2 minutes, but keep a watchful eye to avoid burning.
8. Remove and Serve: Once cooked, remove the halibut from the oven and let it rest for a minute before serving.

These straightforward steps will help you create a marvelous dish that embodies incredible flavors and textures.
