Preheat oven to 400 degrees F. Line a baking sheet with foil and top with a baking rack and spray with cooking spray. (if no baking rack, just spray the foil with cooking spray). Set aside.
Combine the coating ingredients in three shallow containers (like pie tins): 1 - sift together all-purpose flour, paprika, garlic powder, salt and pepper; 2 - whisk together eggs and milk; combine panko breadcrumbs, sharp cheddar and Parmesan cheese.
Season chicken on both sides with kosher salt.
Set up an assembly line to coat the chicken as follows: flour mixture, then egg mixture, and finally cheese mixture. Set pieces in a single layer on the prepared baking rack or baking sheet. Chicken can be close together but should not touch. *Pro-tip - use one hand for wet and one hand for dry coating.
Bake chicken at 400 degrees for 15-20 minutes.or until golden. If you are not using a baking rack, turn the chicken tenders over after about 10 minutes. *For additional browning, turn on the broiler for a few minutes until golden.
Serve immediately with choice of dipping sauce.
You have a few options when it comes to the baking. Both ways will work, one just works a little better than the other.
The first method is just to lay the breaded chicken out on a foil lined baking sheet sprayed with cooking spray.
The second (and preferred) method adds a wire rack on top of the baking sheet to lift the chicken up so it’s able to brown on all sides without having to be flipped over.
