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).
Cook the meat. Pork loin should reach an internal temperature of about 160Âº Fahrenheit. Most recipes will cook the roast in four to six hours on low; on high, the cooking time decreases.Check the roast periodically, and place a meat thermometer in the roast to make sure it is done before serving.(See Reference 1.). good pork loin is boneless meat with little fat. A 1Â½-pound pork roast will feed four people, so choose a roast big enough for everyone. When you get the roast home, do not trim the fat; especially when cooked in a Crock-Pot, the pork roastâs fat will keep it tender and moist.
