Preheat your oven to 400°F (200°C) or your air fryer to 375°F (190°C). Pat the salmon dry with paper towels and place it skin-side down on a baking sheet lined with parchment paper or in your air fryer basket. Season the salmon generously with black pepper.
In a mixing bowl, combine the plain breadcrumbs, shredded Parmesan cheese, Italian seasoning, melted butter, and minced garlic. Mix well until all ingredients are evenly coated with the butter.
Spread the breadcrumb mixture evenly over the top of the salmon fillet, pressing gently to ensure it adheres well.
For the oven method: Bake the salmon in the preheated oven for 15-20 minutes, or until the salmon is cooked through and the topping is golden brown. For the air fryer method: Cook the salmon for about 10-12 minutes, or until the salmon is cooked through and the topping is crispy and golden.
Once cooked, remove the salmon from the oven or air fryer and let it rest for a few minutes. Serve it with your favorite side dishes, and enjoy the delightful flavors of your Garlic Parmesan Crusted Salmon!
