How Do You Know When Tenderloin Is Done?

So you know how long to cook pork tenderloin at 400, but how do you know when it is done?

The best way to know when it’s done is to use a meat thermometer to check the internal temperature of the pork.

Recipe tips

  1. Covering the meat with aluminum foil is not necessary. If you like to have a nice browned outer crust to your meat, we do not recommend it at all.
  2. As per the National Pork Board’s recommendation, it is best to use a meat thermometer to judge the doneness of the pork tenderloin. Any other method will risk inaccuracy.

  4. Always let the pork tenderloin rest for at least five minutes after you pull it out of the oven. This step is really important to lock in the meat’s juices for optimal flavor.
  5. Check your local grocery store for pre-marinated pork tenderloins if you need to save time. There are usually several flavors to choose from!
  6. Fresh herbs such as rosemary, thyme, or sage work well with pork and can be sprinkled on right before baking to add flavor or afterward for a garnish.
