What Is Pork Tenderloin?

Before we discuss the different methods you can use to reheat pork tenderloin, let’s first establish what it is. As its name suggests, this is a cut of pork that is long and thin in size.

Reheating pork tenderloin can be quickly done on the stovetop over gentle heat in a simple frying pan. Regular, cast iron, nonstick — it doesn’t matter too much, but make sure that you have a lid that fits the pan of your choice.

Reheating in an uncovered pan will result in dried-out meat, but a lid helps trap all that precious moisture and steam, so the pork absorbs it and tastes just as good as it did the first time.

If your pork tenderloin has a nice crust on the outside, it won’t be as crisp as when you first made it, but we are willing to sacrifice that tiny bit of texture for juicy meat.

How to Do It

1. Start by picking out your pan. Choose one that will fit the meat in a single layer; if your pork tenderloin is already sliced, make sure you have a lid for that pan.

For the whole tenderloin: We turned it every two to three minutes, which took 12 to 15 minutes.

Our pork tenderloin, which had a perfect, slightly pink center when we first cooked it, was reheated beautifully with this method. It was juicy, warmed through, and didn’t take long.
