Notes
Be sure to not over cook your pork chop as it will dry it out. Cook the pork chop until it reaches 145 degrees F. The cooking time will vary depending on how thick your pork chop is so use a meat thermometer to check your temperature.Instead of a blade cup pork chop you can also use a pork rib chop or loin chop.
