Prep: Pat the cod fillets completely dry with paper towels to ensure a crispy exterior.
Season: In a small bowl, mix olive oil, lemon juice, garlic powder, paprika, onion powder, salt, and pepper.
Coat: Brush this mixture evenly over both sides of each fillet.
Arrange: Place the seasoned fish in the air fryer basket in a single layer (do not overlap).
Air Fry: Cook at 400°F (200°C) for 8–10 minutes. The fish is done when golden brown and internal temperature is 145°F.
Serve: Garnish with fresh parsley and serve immediately.
