Follow these step-by-step instructions to prepare your Garlic Parmesan Crusted Halibut:

1. Preheat the Oven:
   Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or lightly grease it with cooking spray.
2. Prepare the Crust Mixture:
   In a medium-sized bowl, combine the grated Parmesan cheese, panko breadcrumbs, chopped parsley, minced garlic, lemon zest, salt, and black pepper. Mix well to ensure the ingredients are evenly distributed.
3. Coat the Halibut:
   Pat the halibut fillets dry with paper towels. Brush each fillet with melted butter, ensuring an even coating. This will help the crust adhere to the fish and add rich flavor.
4. Apply the Crust:
   Press the Parmesan breadcrumb mixture onto the top of each halibut fillet. Make sure the crust is packed tightly and covers the entire surface.
5. Drizzle with Olive Oil:
   Drizzle a bit of olive oil over the coated fillets. This will help the crust become golden and crispy as it bakes.
6. Bake the Halibut:
   Place the crusted halibut fillets on the prepared baking sheet. Bake in the preheated oven for 12-15 minutes, or until the fish flakes easily with a fork and the crust is golden brown.
7. Add Lemon Juice:
   Remove the halibut from the oven and drizzle with fresh lemon juice for a burst of citrus freshness.
8. Serve:
   Serve the Garlic Parmesan Crusted Halibut hot with lemon wedges on the side for an extra zing.
