Using a food processor, you can create a flavorful garlic Parmesan crust for your air fryer salmon. Blend together ingredients like garlic, Parmesan cheese, breadcrumbs, and herbs to make the crust. Coat the salmon fillets with the crust mixture and let them sit for a while. Then, place the salmon in the air fryer and cook until the crust becomes crispy and golden. Serve it with a squeeze of lemon juice and a sprinkle of fresh parsley for a burst of freshness.
