Preheat the air fryer. Set it to 400°F (200°C) for 3–5 minutes.
A hot basket helps the coating crisp right away.
Prep the chicken. Pat chicken tenders dry with paper towels. This helps the coating stick and prevents steaming.
Set up a breading station. In one shallow bowl, add the flour. In a second bowl, whisk eggs with water.
In a third bowl, mix panko, Parmesan, garlic powder, onion powder, Italian seasoning, smoked paprika, salt, and pepper. If you like heat, add a pinch of cayenne.
Dredge the chicken. Coat each tender lightly in flour, shake off excess. Dip into the egg, then press into the panko-Parmesan mixture until fully covered.
Use one hand for wet and the other for dry to keep things tidy.
Spray for crispiness. Lightly spray both sides of the breaded tenders with oil. This promotes even browning.
Arrange in the basket. Place tenders in a single layer in the air fryer basket. Do not overcrowd. Cook in batches if necessary.
Air fry. Cook at 400°F (200°C) for 8–10 minutes, flipping halfway.
Spray again after flipping if any dry spots remain. Tenders are done when golden and the internal temperature reaches 165°F (74°C).
Rest briefly. Let the tenders sit on a wire rack for 2–3 minutes. This preserves the crunch and keeps the coating from steaming.
Serve. Squeeze with lemon, sprinkle with parsley, and serve with your favorite dips.
