Prepare the coating mixture: combine grated Parmesan, panko breadcrumbs, salt, black pepper, garlic powder, and smoked paprika in a shallow dish.
Bind the fish: lightly beat eggs. Pat tilapia fillets dry, then dip each fillet into the egg wash to coat.
Coat the fillets: press each fillet into the Parmesan breadcrumb mixture, covering both sides evenly.
Preheat the Air Fryer to 400°F (200°C) for 3 minutes.
Air fry the tilapia fillets: arrange fillets in one layer without crowding. Cook for 8-10 minutes, flipping halfway through.
Serve and garnish: let fish rest briefly after cooking. Add fresh lemon juice or herbs as desired before serving.
