A pork tenderloin is a versatile cut of meat that can be cooked in many ways. To cook it properly, look for one that’s pink and not too fat. When you’re ready to eat your roast tenderloin, slice it into medallions or cutlets with the grain or against the grain (depending on how you want them). You can also shred it for use in sandwiches or stir-fries.

  • Season the pork tenderloin with salt and pepper, and then rub it with oil or butter. Place it on a rack over a roasting pan (or just on a sheet tray if you don’t have anything else), fat side up so that it doesn’t dry out during cooking, then place in oven for 20 minutes per pound of meat until internal temperature reaches 145 degrees F at its thickest part (about 10 minutes per pound).
