What is Pork Tenderloin?
Pork tenderloin [1] is a cut of meat taken from the muscle tissue along the back of the pig. It’s lean, tender and juicy when cooked properly, making it a great option for dinner parties or weeknight meals. This particular cut is also relatively inexpensive compared to other cuts of pork, so you won’t break the bank when you decide to make it.
Pork tenderloin is not the same as pork loin [2]. The difference between them lies in their location on the pig; while they are all taken from the back of the animal, they come from different parts.
- Pork tenderloin is found near the spine and extends to either side of it . The tenderloin is a long, narrow muscle that runs along the spine of the pig and has very little fat.
- Pork loin is taken further down towards the hindquarters. Pork loin is much bigger than tenderloin and requires longer cooking times.

However, if you’d like to cook it slowly and let more of the juices stay in the meat, then cooking it at 350°F is a good option.

If you choose to sear the pork tenderloin before roasting, then you’ll need to reduce the cooking time to 25 minutes for a 2-pound roast and 35 minutes for a 3-pound roast.
What is searing?
Searing is a cooking technique used to quickly brown the outside of the meat. This can be done on the stovetop in a skillet or grill pan, or in the oven by setting it to a high temperature for 5-10 minutes before reducing it to finish cooking. Searing will help lock in moisture and create a caramelized crust on the outside of the pork, giving it more flavor.

Regardless of whether or not you sear your pork, remember that it’s important to check the internal temperature with a meat thermometer throughout cooking and take it out when it reaches 145°F (63°C).

Never Cook Frozen Pork Tenderloin
It’s important to remember that you should never cook frozen pork tenderloin in the oven at 400°F. Frozen pork needs to be thawed before it can be cooked, and this process must take place in the refrigerator or another cold environment since cooking frozen meat can result in foodborne illnesses.
When thawing your pork, place it in the refrigerator for a few days until it is completely thawed. Once it’s fully thawed, you can cook the pork tenderloin as usual according to the instructions given above.
For best results, always make sure that your pork is thoroughly thawed before cooking it in the oven at 400°F
Use Aluminum Foil if the Meat is Particularly Lean
If your pork tenderloin is particularly lean, you may want to consider wrapping it in aluminum foil before roasting. This will help keep any moisture that is released during cooking inside the foil and avoid it evaporating away. You can also add a bit of liquid (such as broth or wine) to the bottom of the roasting pan for extra moisture.
Remember to remove the foil for the last 10 minutes of cooking. This will allow the pork to brown and crisp up on the outside.
A Rolled Tenderloin Will Take Longer to Roast at 400°F
If you’re roasting a rolled pork tenderloin, it will take longer to cook than an unrolled one. Generally speaking, a 2-pound roast will require 45 minutes of cooking time at 400°F (204°C) whereas a 3-pound roast should be cooked for 1 hour and 15 minutes. As always, use a meat thermometer to check the internal temperature and take it out of the oven when it reaches 145°F (63°C).
