1 Place pork tenderloin in roasting pan. 2  Roast for 30 minutes. 3  Turn the pork over and roast for another 25 minutes. 4  The pork tenderloin is ready when the internal temperature reaches 145 degrees Fahrenheit (63 degrees Celsius).
Best Answer: For your seasoned pork loin, preheat your oven to 400 degrees F or (200C). Place the seasoned pork in the preheated oven and immediately turn the oven down to 350F (175C). Roast the pork loin or tenderloin for about 70-90 minutes or until it reaches an internal temperature of 145-150F (73-75C) degrees. If you prefer your pork cooked to medium well, cook it to an internal temperature of 155-160F (78-80C) degrees.
