Preheat your oven to 400°F (200°C).

In a medium bowl, combine the grated parmesan, breadcrumbs, minced garlic, melted butter, olive oil, lemon juice, salt, and pepper. Stir until it resembles wet sand.

Line a baking sheet with parchment paper and place the halibut fillets on it.

Press the crust mixture onto the top of each halibut fillet, aiming for a 1/4-inch layer.

Bake the halibut for 12-15 minutes until golden-brown and flakiness is achieved.

Let the halibut rest for a minute, then garnish with chopped parsley before serving.
