If your pork chops are tough, it's likely because they were overcooked. Pork chops should be cooked to an internal temperature of 145 degrees Fahrenheit. Any higher and the pork chops will begin to dry out and become tough. Use a meat thermometer to check the internal temperature of your pork chops to ensure they are cooked properly.
There are a few other factors that can contribute to tough pork chops. If the pork chops are too thick, they will be more difficult to cook evenly. Try to cut your pork chops no more than 1-inch thick to prevent them from becoming tough. Another factor to consider is the quality of the pork chops. If they are not fresh or of a lower quality, they will be more difficult to cook properly. Be sure to purchase fresh, high-quality pork chops for the best results.
