In a medium bowl, combine panko bread crumbs, grated Parmesan cheese, garlic powder, paprika, black pepper, and salt. Mix well and set aside.
Pat the cod fillets dry with paper towels to remove any moisture.
In a shallow dish, beat the egg and set it next to the panko mixture for an assembly line setup.
Dip each cod fillet first into the beaten egg, allowing any excess to drip off, then dredge it in the panko-Parmesan mixture, pressing gently to ensure the coating sticks well. Repeat for all fillets.
Preheat the air fryer to 400°F (200°C) for about 5 minutes.
Lightly brush the coated cod fillets with olive oil on both sides. Place the fillets in the air fryer basket in a single layer, making sure they are not touching. Cook for 10-12 minutes, or until the crust is golden and the fish flakes easily with a fork.
Once done, remove the cod fillets carefully and sprinkle with fresh chopped parsley for added flavor and color.
Notes
Serve on a bed of lemon-infused arugula or mixed greens with lemon wedges.
