01 - Preheat oven to 425°F. Line a baking sheet with parchment paper and lightly grease with cooking spray.
02 - Arrange three shallow bowls: place flour in the first bowl, whisk together eggs and milk in the second bowl, and mix panko, Parmesan, garlic powder, paprika, salt, and pepper in the third bowl.
03 - Pat chicken tenders dry with paper towels. Dredge each piece first in flour, then in egg mixture, then in the panko mixture. Press gently to ensure coating adheres properly.
04 - Place coated chicken tenders on the prepared baking sheet in a single layer. Lightly spray tops with cooking spray for even browning.
05 - Bake for 22–25 minutes, turning halfway through cooking, until golden brown and cooked through to an internal temperature of 165°F.
06 - While chicken bakes, whisk together Dijon mustard, honey, mayonnaise, lemon juice, salt, and pepper in a small bowl until smooth and well combined.
07 - Transfer chicken tenders to a serving platter and serve immediately with honey mustard sauce for dipping.
