Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it.
Pat the chicken tenders dry with paper towels.
In one shallow bowl, whisk together the egg and milk.
In another bowl, combine the panko breadcrumbs, Parmesan cheese, garlic powder, onion powder, paprika, Italian seasoning, salt, and black pepper.
Lightly brush the chicken tenders with olive oil.
Dip each chicken tender into the egg mixture, then coat evenly in the breadcrumb mixture, pressing gently so the coating sticks.
Arrange the coated chicken tenders on the prepared baking sheet, leaving space between each piece.
Lightly spray the tops with cooking spray or drizzle with a little olive oil.
Bake for 18 to 20 minutes, flipping halfway through, until the coating is golden and the chicken reaches an internal temperature of 165°F (74°C).
Let the chicken tenders rest for 5 minutes before serving.
Garnish with fresh parsley if desired and serve with your favorite dipping sauce.
