Preheat the air fryer: Set to 400°F (200°C) for 3–5 minutes so it’s hot when the fish goes in.
Prep the dredging station: In one shallow bowl, add flour with a pinch of salt and pepper.
In a second bowl, beat the eggs. In a third bowl, mix breadcrumbs, Parmesan, garlic powder, onion powder, paprika, salt, and pepper.
Dry the fish well: Pat fillets thoroughly with paper towels. Dry fish helps the coating stick and crisp.
Coat the tilapia: Dredge each fillet in flour (shake off excess), dip in egg, then press into the breadcrumb mixture. Make sure every spot is covered.
Oil for crispness: Lightly spray both sides of each breaded fillet with oil.
Also spray the air fryer basket to prevent sticking.
Air fry the first side: Arrange fillets in a single layer in the basket, not touching. Cook at 400°F (200°C) for 5–6 minutes.
Flip and finish: Carefully flip, spray again, and cook 3–5 more minutes. The coating should be golden and the fish should flake easily with a fork. Internal temp should reach 145°F (63°C).
Rest and serve: Let the fish sit 2 minutes to set the crust.
Squeeze with lemon and garnish with parsley if you like.
