What’s the difference between pork loin and pork tenderloin?

First things first, let’s clear up a common confusion! While they may sound the same and are actually cut from the same part of the pig, pork loin and pork tenderloin are NOT the same things. Here’s a comparison of the two:

• Pork loin is a larger cut of meat that is usually sold as a 3-5 pound roast. It is fattier than pork tenderloin, usually comes with a fat cap on top, and can come as either boneless pork loin or bone-in. You can find our favorite pork loin recipehere.
• Pork tenderloin is a smaller cut of meat that usually weighs around one pound. The tenderloin is from a muscle that runs along the spine of the pig and isn’t used for movement. As a result, it’s much more tender than other cuts of meat. Pork tenderloin is also a lean cut of meat and has a very mild flavor.

How to Prepare Pork Tenderloin

As mentioned before, pork tenderloin is a very lean cut of meat – but what exactly does that mean? In addition to being a low-fat choice of protein, it is also very low on flavor. If you want a flavorful pork tenderloin, we recommend marinating it or seasoning it heavily. The good news is that since it is so mild, pork tenderloin takes on flavor easily – you just have to give it a little time. While you can certainly add flavor by using a spice rub, we love adding flavor by marinating pork tenderloin in one of our3 delicious pork tenderloin marinades– Balsamic and Rosemary (a delicious blend of herbs, garlic powder, balsamic vinegar, dijon mustard, and olive oil), Maple Dijon (a great sweet and savory combo), or Sesame Ginger (a tasty Asian-inspired choice that includes soy sauce or coconut aminos, honey, and red pepper flakes)! Allow your pork to marinate for at least 30 minutes, or, if you have the time, up to 24 hours.

How to Cook Pork Tenderloin in the Oven

While we also love grilling pork tenderloin (or even cooking it all day in the slow cooker), today’s technique is dedicated to how to roast pork tenderloin in the oven, because it’s the most accessible cooking method year-round. Once you have marinated your pork tenderloin, it’s time to get cooking! Just follow the steps below to perfect pork tenderloin.

Our main goals with pork tenderloin are to build flavor and not overcook it. Searing the pork tenderloin goes a long way to building flavor! It caramelizes the marinade, creating a delicious golden brown crust on the outside. It also helps seal the juices before you bake it.

Step 1: Sear the Pork Tenderloin

To sear the pork tenderloin, grab your favorite cast iron, or another heavy-bottomed, oven-safe pan, add about 1/2 tablespoon of oil, and heat it over medium-high heat. Then, take your pork tenderloin and let the excess marinade drip off, and place it in the pan and sear for about 3-4 minutes, until browned. After 3-4 minutes, flip the pork tenderloin over and sear for an additional 3-4 minutes, until browned. While you can sear it on all 4 sides if you’d like, we find that searing on two sides works just fine!

Step 2: Bake the Pork Tenderloin

Now that the pork tenderloin is seared, you can either bake it in the same pan you seared it in, or transfer it to a rimmed baking sheet. Brush the pork tenderloin with additional marinade, then bake in a preheated oven at 425°F for about 15-20 minutes, until the pork reaches a temperature of 145°F, then remove it from the oven. Cooking the pork tenderloin at the high temperature of 425 degrees F helps it cook quickly and prevents it from drying out.

Step 3: Rest the Pork Tenderloin

Finally, you’ll want to let the pork tenderloin rest for about 8-10 minutes before serving, if you skip this step and cut into it immediately, the juices will run out of it and you’ll be left with dry pork.
