Pork Tenderloin – How to cook pork tenderloin, roasted to a juicy perfection in the oven. Easy recipe for a delicious dinner with simple seasonings and potatoes.

Growing up in a meat and potatoes household, I have a love relationship with meat and potatoes, even though we don’t always eat the second part of that equation. My guys love meat too, so we occasionally gravitate toward pork for dinner.

Pork tenderloin is the best of both worlds because it’s super easy to make and not time consuming at all. It’s also delicious with a good side of mashed potatoes or green beans or even a colorful salad.

Who doesn’t love an easy dinner the whole family will eat? And it’s healthy to boot.

Oven roasted pork tenderloin usually takes less than half an hour to bake. There’s hardly any prep time either.

FIRST, LET’S TALK ABOUT THE DIFFERENCE BETWEEN PORK LOIN AND PORK TENDERLOIN

Because yep, there is a difference. Don’t feel bad if you didn’t know, because I didn’t realize it either; I thought they were one and the same.

I share this with you because I want to make sure you get the right cut of meat for this recipe.

As it happens, pork loin is speaking about more of a pork roast, while pork tenderloin is more of a boneless filet. Pork tenderloin is that longer, thinner piece of pork that almost looks like a long roll.

The Kitchn actually has a really helpful explanation for the difference between pork loin and pork tenderloin.

TIPS FOR HOW TO COOK PORK TENDERLOIN

This pork tenderloin recipe is really simple, and we actually only use a couple of seasonings that you likely already have in your kitchen.

  • Your first step is to dry the pork tenderloin with a paper towel. It’ll likely have a little bit of water in the package with it, so just pat it dry.

  • Then rub it down with the olive oil.

  • Sprinkle the salt and pepper over the entire pork tenderloin, and rub it in well.

  • Sear the meat in a large skillet (preferably a skillet you can also bake it in), being sure to turn it so that both sides slightly brown.

And now you’re ready to roast it.

Note: You’ll want to parboil potatoes and veggies just a bit, so they get completely cooked in the short amount of time they’ll cook with the meat.

PORK TENDERLOIN COOKING TIME

How long to cook pork tenderloin really depends on a number of factors, including both your oven and the size of your tenderloin.

We cooked ours for about 25 to 30 minutes.

You want to make sure that it reaches the recommended internal temperature for pork, which is 145 to 160°F. We prefer not to mess around with pork and always let it come to temp before eating.
