Preheat and prep: Heat the oven to 425°F (220°C).
Line a large baking sheet with parchment paper and lightly brush or spray with oil. If using an air fryer, set it to 400°F (205°C).
Set up the dredging station: Place the flour in one shallow bowl. In a second bowl, whisk the eggs with the milk.
In a third bowl, combine panko, Parmesan, garlic powder, onion powder, paprika, salt, pepper, and olive oil. Toss to coat the crumbs evenly; this helps them crisp.
Dry the chicken: Pat the chicken tenders dry with paper towels. This helps the coating stick and keeps the crust crunchy.
Coat the chicken: Working one piece at a time, dredge in flour (shake off excess), dip in the egg mixture, then press into the Parmesan-panko mixture until well coated.
Place on the prepared baking sheet in a single layer.
Add a little oil: Lightly mist or brush the tops with oil. This boosts browning and crunch.
Bake: Cook for 14–18 minutes, flipping once halfway through. Tenders are done when golden brown and the internal temperature reaches 165°F (74°C).
Thicker pieces may need an extra 2–3 minutes.
Air fryer option: Arrange in a single layer and cook at 400°F for 9–12 minutes, flipping halfway. Work in batches if needed.
Rest and serve: Let the tenders rest for 3 minutes. Squeeze over a little lemon juice, sprinkle with parsley, and serve with your favorite sauces.
