Can You Reheat Pork Tenderloin?

The real question is how to accomplish what can often feel like a Herculean task.  

After all, it could go so horribly wrong.  

In general, it’s helpful to keep in mind that most foods that are baked or grilled are best reheated using an oven or a grill, returning them from whence they came. Meanwhile, foods that are breaded or fried, much trickier to be sure, often take better to the oven or the air fryer for reheating.  

With pork tenderloin, we will likely be best off reheating using either the oven or the air fryer. But we’ll explore all our options just to be sure.  

Should You Reheat Pork Tenderloin? 

Oh, but it’s pork. 

And no one wants to get sick from eating bad pork.

But before you do anything, do your own research to be sure you are following proper food-handling and safety procedures, so you don’t end up with a foodborne illness.

How to Reheat Pork Tenderloin in the Oven 

Reheating pork tenderloin in an oven can be a blessing and a curse.  

You need to be sure you heat it thoroughly, ensuring it is warm and up to proper temperature, but you also run the risk of drying it out from overheating.  

Your best bet is to reheat at medium heat and not for too long by following these steps:  

  1. Preheat your oven to 325 degrees Fahrenheit.  
  2. Place your tenderloin in an oven-safe dish with a cover.  
  3. Put the dish in the oven for 20 minutes or until the pork’s internal temperature reaches 165 degrees.  
  4. If you need to, cook in additional increments of 5 minutes, checking your internal temp again after each increment.  

How to Reheat Pork Tenderloin in the Microwave 

The microwave is not always a good idea when it comes to reheating meat, especially pork. It can cause the meat to turn out rubbery.  

Follow these directions to avoid this disaster:  

  1. Cut your tenderloin into 1-inch thick slices.  
  2. Transfer your slices to a microwave-safe dish with a cover.  
  3. Set your microwave to medium heat, or 50% power, and heat for 5 minutes.  
  4. Check your internal temperature for 165 degrees Fahrenheit. If it needs more time, cook in 2-minute increments, checking the temp again each time.  

How to Reheat Pork Tenderloin in an Air Fryer 

Reheating pork tenderloin in an air fryer can be a quick and easy way to enjoy your leftovers. Use these directions for the best results: 

  1. Preheat your air fryer to 350 degrees Fahrenheit.  
  2. Slice the pork into 1-inch thick slices.  
  3. Place your medallions in the air fryer and cook for 3 to 4 minutes then check your internal temperature.  
  4. If they need more time, cook in 1-minute increments until heated thoroughly.  
  5. Enjoy! 

How to Reheat Pork Tenderloin on a Grill 

Because pork tenderloin is so easy to dry out, and you don’t really want to place it on an open flame or in a device as hot as a grill, reheating pork tenderloin on a grill is not advised.  

What you can do is use these steps to reheat your pork tenderloin in a smoker, if your grill has this feature, or if you happen to have a smoker.  

  1. Bring your smoker up to 225 degrees Fahrenheit.  
  2. Place your whole leftover pork tenderloin in an aluminum pan and put the pan in your smoker.  
  3. Cook your pork tenderloin for 15 minutes then check for the right internal temperature.  
  4. You can continue to cook in 3-minute increments if necessary.  

How to Reheat Pork Tenderloin in a Toaster Oven 

If all you’ve got to work with is a toaster oven, we can work with that! 

It will take a bit longer, but you should get the same results as you would with the conventional oven. Just follow these steps: 

  1. Because the toaster oven is smaller, you will need to slice your tenderloin into 1-inch thick medallions and place them on a baking sheet. Cover the baking sheet with foil to trap in moisture.  
  2. Heat your toaster oven to 325 degrees Fahrenheit and place your baking sheet inside.  
  3. Cook for 25 minutes and check the internal temperature.  
  4. You can continue to cook in 5-minute increments if necessary.
