You do not want to overcook a pork loin roast. Closely monitor the internal temperature while cooking. For optimal results, remove from oven when internal temperature at the center of the roast reaches 142°(F). Do this by checking the center of the roast with an instant read meat thermometer or internal temperature probe.

The total time in oven will be approximately 60 minutes for a 3lb roast; closer to 90 minutes for a 4lb roast.
