Slice the chicken breasts horizontally into thinner, evenly sized cutlets.
Gently pound any thick areas until the chicken has a relatively even thickness.
Season the chicken with part of the salt and black pepper.
Mix flour, garlic powder, onion powder, salt, and pepper in a shallow dish.
Whisk the egg with water in a second dish.
Combine panko, Parmesan, paprika, Italian seasoning, garlic powder, salt, and pepper in a third dish.
Coat each chicken cutlet in flour, shaking off excess.
Dip the chicken into the egg wash and allow excess egg to drip away.
Press the chicken firmly into the panko mixture on both sides.
Heat olive oil and butter in a skillet over medium heat.
Cook the chicken until golden brown on both sides and the thickest part reaches 165°F (74°C).
Transfer the chicken to a wire rack and let it rest briefly.
Serve immediately with your favorite sides and sauce.
