how long do you cook a pork tenderloin
Roast the tenderloin at 450 F for 10 to 15 minutes to aid browning, then reduce the oven to 325 F. Roast the tenderloin until an instant-read thermometer inserted into the thickest part shows an internal temperature of 140 F.Remove the tenderloin from your oven and cover it loosely with aluminum foil.Let it rest for 10 minutes before carving, which gives its internal temperature time to rise to 145 F, the temperature recommended by the U.S. Department of Agriculture for food safety.ub or spray your tenderloin lightly with oil, and season it with salt and pepper or other flavorings as you wish. The tenderloin can be broiled whole, cut into individual 4- to 8-ounce portions, or sliced into medallions of 1 1/2 to 2 inches' thickness.
