What Is Pork Tenderloin?

Few other proteins are as tender and juicy as a pork tenderloin. In addition to its fabulous flavor, this meat is incredibly easy to cook.

Pork tenderloin is also called pork filet or pork tender. It comes from the muscle that runs alongside the backbone. This boneless cut of meat is very lean and cooks quickly.

Ingredient Notes

See recipe box below for ingredient amounts and full recipe instructions.

  • Pork tenderloin: Most packages come with two filets inside. If you're cooking for one you might not want to make them both. In fact, when I cook for myself I use about 8 ounces of pork filet, which is about half of one tenderloin. You can wrap the remaining tenderloins in freezer paper, heavy duty freezer wrap, or double wrap in plastic wrap to freeze and cook later. You can certainly cook both tenderloins and the leftovers keep wonderfully for days. Use pork leftovers in sandwiches, mixed in with pasta, or in salads.
  • Italian seasoning, salt, black pepper, garlic powder: For flavor.
  • Olive oil: I use extra virgin olive oil in this pork tenderloin recipe as well as in every other recipe on One Dish Kitchen that calls for olive oil. Extra virgin olive oil is the least processed form of olive oil. It is an unrefined oil and the highest-quality olive oil you can buy. Because of the way extra virgin olive oil is made, it retains more true olive taste. It also contains more of the vitamins and minerals found in olives. It's my favorite type of olive oil to use but you may use a lighter olive oil instead.
  • Butter: I add salted butter to the pork after it cooks in the oven. Adding a little butter, then covering the pan while the pork rests keeps the meat extra juicy. The butter melts into the pork and helps to create the most incredibly delicious sauce!

How To Make This Recipe

  1. Place a cast iron skillet in the oven on a middle rack and heat the oven to 450 degrees F (230 degrees C). The skillet will heat along with the oven. Remove from the oven and add olive oil to the skillet. Give the pan a swirl so that the oil coats the entire bottom.
  2. Mix together the Italian seasoning, salt, pepper, and garlic powder in a small bowl. Sprinkle the seasoning mix over the pork and rub the spices in with your fingers. Place the pork in the skillet and using oven mitts, return the skillet to the oven and bake for 10 minutes.
  3. After 10 minutes, remove the skillet from the oven and using tongs, flip the pork over. Reduce the oven temperature to 400 degrees F (200 degrees C) and continue roasting another 15 minutes. 
  4. Remove the skillet from the oven. Add the butter to the pan and cover with a large plate, a pan lid, or foil. Let the pork rest 15 minutes before serving. The pork is done when its internal temperature registers 145 degrees in the thickest part of the meat.
  5. Remove the foil. Spoon the butter sauce over the pork before slicing.
  6. Transfer the pork to a plate and pour more of the amazing sauce over the top.

Expert Tips

  • Season the pork on all sides: Make sure the tenderloin is completely coated with the spices and feel free to experiment with your favorite spices and spice blends. You can even season the pork simply with just salt and pepper.
  • Trim fat if necessary: Most tenderloins are sold already trimmed of fat. If the one you purchase still has a bit of fat left on, remove it with a sharp knife.
  • Don't forget the butter: The heat from the pan will melt the butter which will mix with the juices of the pork. This makes for a wonderful sauce to cover the pork.
  • Be sure to cover the pork before slicing: Letting the pork "rest" for about 15 minutes after cooking is important. It allows the juices to reabsorb back into the meat so you are sure to have the juiciest pork possible.

Frequently Asked Questions

What Do I Look For When Buying Pork Tenderloin?

Pork tenderloin is found in the meat section of the grocery store. The tenderloin is the small cut of pork tenderloin, usually weighing around 1 to 1 1/2 pounds, you'll usually see two in a sealed package.  
You might see some tenderloins in a marinade. Personally, I don't purchase these. I like to season the meat myself, this controls the amount of salt and oil used.

How Do I Freeze Pork Tenderloin?

Raw pork should be wrapped thoroughly and tightly. Use butcher paper or double wrap the pork in plastic wrap and then place in freezer zip topped bags. You might like to consider wrapping the pork in convenient portions, 8-ounces tends to be a good size to serve one or two.
Well wrapped tenderloin will keep well in the freezer for up to six months.
Raw pork should be thawed in the refrigerator for several hours or overnight depending on its size.

How Should I Use Leftover Pork Tenderloin?

Pork tenderloin leftovers are wonderful. If you'd like to make the entire tenderloin follow the same cooking instructions and double the ingredient amounts for each pork tenderloin.
Consider using leftover pork in sandwiches or mixed in with pasta.

        I haven’t made this yet, but I’m sure it is 5 stars. But I will be making this for two and was wondering in what besides a cast iron skillet can it be cooked?
