Pat the tenders dry. In one shallow bowl whisk the eggs with the milk; in a second bowl combine the panko, Parmesan, Italian seasoning, garlic powder, salt, and pepper.
Dip each tender in the egg mixture, then press it into the panko mixture to coat both sides.
Preheat air fryer to 400°F. Spray basket lightly with oil.
Place tenders in a single layer, spray tops lightly, and air fry 8–10 minutes, flipping halfway, until golden and 165°F inside.
Let rest 2 minutes. Serve with ketchup, ranch, or a squeeze of lemon. My youngest dips everything in ranch and gives a thumbs-up.
