Take each pork chop and spread some mustard-mayo mixture onto 1 side. Place that pork chop in the pan COATED side down. Press the pork chop into the panko bread crumbs so that they are pressed into the mustard-mayo mixture.
Take your pastry brush and coat the top side of each pork chop.
Take the remainder of the panko bread crumbs and evenly sprinkle them over the pork chops to coat thoroughly. Take your fingers and press the panko bread crumbs down into the mustard-mayo mixture.
Bake pork chops for 20-25 minutes or until internal temperature reaches 145 degrees. If you want the panko crust to be extra crispy, broil for about 5 minutes.
