Preheat oven to 425F. Line a sheet pan with parchment or foil, if desired and spray with oil.
Season chicken with salt. Place egg in a shallow bowl. In a second shallow bowl, add the breadcrumbs and panko.
Dip chicken in the egg, then into the breadcrumb mixture and shake off excess and place on a sheet pan. Spray both sides of the chicken generously with oil.
Bake the chicken 18 minutes flipping halfway until cooked through. Serve with your favorite dipping sauce.
Notes
5 tbsp of the breadcrumb mixture gets tossed after coating and has been subtracted from the nutrition info.
