If you’re looking for a new and exciting way to cook pork tenderloin, consider roasting it in the oven. While cooking times vary based on the thickness of the tenderloin, an average 2-pound roast takes about 30 minutes to reach 145 degrees F (medium-rare), while a 1-pound roast takes 20 minutes less time. The good news is that this lean cut doesn’t need much more than salt and pepper before going into the oven—but if you want to add some flavor, try rubbing it with olive oil plus herbs like rosemary or thyme before putting it in the oven.
