How to Cook Pork Tenderloin

For the best roasted pork tenderloin, just a few savory herbs and seasonings, like a simple southwest seasoning. That is all you need to bring out the mellow flavor of pork! Because of the thin layer of fat that covers the pork tenderloin, there is no need to add very much additional oil either.

  1. Score the top of the fat cap in a criss-cross fashion.
  2. Rub the seasonings in for a slightly crunchy topping. And that’s basically it!
  3. Roast the tenderloin.

Forget about the tired old side dishes like applesauce. Try wrapping your pork tenderloin in bacon or serving with roasted asparagus or green beans a one-pot meal that is sure to impress!

How Long to Cook Pork Tenderloin

The key to tender pork is to get the perfect pork tenderloin temperature. It’s easy if you have a meat thermometer and know how to use it, the rule of thumb is a full 25 minutes per pound at 425°F.

If vegetables or other liquids are added to the pan, it will require a longer cooking time. Other items in the pan will add to the flavor of the finished product though. So be sure to take that into account!

Either way, the best way to make sure your pork tenderloin roast recipe is successful is to:

  • Check the temperature every 20 minutes or so, be sure to check in different places on the roast for accuracy.
  • Whether you are roasting a tenderloin or the larger pork loin, pull the roast out when the internal temps reach between 145°F  to 160°F.
  • Let it sit for 5 to 10 minutes.  As the roast cools, the juices will be sealed in, creating a juicy, flavorful entrée that will have your guests coming back for more!

Remember to create a savory sauce by reducing with broth or simmering with cream and butter for a creamy sauce.  A few sautéed mushrooms, shallots, and a sprig of rosemary or thyme and dinner is served!
