Cooking pork tenderloin to the proper internal temperature is essential for ensuring its safety and tenderness. The cooking time can vary depending on the size and thickness of the tenderloin, as well as the cooking method used.
As a general rule, pork tenderloin should be cooked to an internal temperature of 145 degrees Fahrenheit (63 degrees Celsius) as recommended by the USDA. Using a meat thermometer is the most accurate way to measure the internal temperature of the pork tenderloin.
