In this article, we’ll explore the best ways to cook pork tenderloin per pound, including tips on oven temperature, seasoning, and using a meat thermometer. Whether you’re a seasoned cook or a beginner in the kitchen, read on to learn how to cook the perfect pork tenderloin for your next meal.

How Long To Cook Pork Tenderloin Per Pound?

The cooking time for pork tenderloin will vary depending on the size of the roast. As a general rule, you should plan on roasting the meat for 25 minutes per pound. For example, if you have a 1-pound tenderloin, you’ll cook it for 25 minutes, and if you have a 2-pound roast, you’ll cook it for 50 minutes.

However, it’s important to note that pork tenderloin is leaner than other cuts of pork, so it can dry out quickly if you overcook it. To avoid this, use a meat thermometer to check the internal temperature of the pork before you take it out of the oven. The USDA recommends cooking pork to an internal temperature of 145°F, which should result in a juicy, flavorful roast.

Understanding Pork Tenderloin

Pork tenderloin is a specific cut of meat that comes from the loin muscle of a pig. It is a long, thin cut of meat that is typically cylindrical in shape and has very little marbling. Because the muscles used in this area are not primarily used for movement, the resulting meat is both tender and lean.

To prepare pork tenderloin, it can be roasted whole, sliced into medallions for sautéing, or grilled. When roasting a whole tenderloin, it’s recommended to truss it with twine to shape and cook it evenly. Pork tenderloin can also be seasoned with spice rubs, marinades, or fresh herbs like sage and rosemary to enhance its flavor.

When cooking pork tenderloin, it’s important to avoid overcooking it as it can quickly become dry. A general rule of thumb is to roast the meat for 25 minutes per pound at 145°F internal temperature. Using a meat thermometer is highly recommended to ensure that the pork is cooked to perfection.

Preparing Pork Tenderloin For Cooking

Before cooking pork tenderloin, it’s important to prepare it properly. Start by removing any silver skin or fat with a boning knife. To do this, make a cut between the skin and the meat and work the knife away from your hand, cutting the skin away from the meat as you go. Repeat until all of the skin is removed. If desired, you can also remove any bits of fat or sinew.

Next, make sure the tenderloin is of equal thickness by folding up the thinner end so that it’s doubled a bit there. Your goal is for the length of the pork tenderloin to be of fairly equal thickness. Secure the doubled up part with metal skewers if you’re grilling, or butcher’s twine or wooden toothpicks if you’re baking.

To add flavor and moisture to the pork tenderloin, consider marinating it before cooking. A simple marinade of apple cider vinegar, Dijon mustard, honey, onion powder, and salt can make the pork even juicier. Alternatively, experiment with your favorite flavor combinations as a marinade.

When ready to cook, preheat your oven to 425°F. Season the pork tenderloin with salt and pepper and sear it in a hot pan for about 8 minutes on all sides to achieve a beautiful golden crust. Then transfer it to a rimmed baking sheet and brush it with additional marinade before baking in the preheated oven for about 15-20 minutes, until the internal temperature reaches 145°F.

Let the pork tenderloin rest for at least 5 minutes before slicing to allow the juices to redistribute and keep it from drying out. With these preparation tips and cooking guidelines, your pork tenderloin will come out juicy and flavorful every time.

Choosing The Right Cooking Method

When it comes to cooking pork tenderloin, there are several methods to choose from, each with its own advantages and disadvantages. The most common methods are roasting, grilling, baking, slow cooking, and air frying.

Roasting is a popular method that involves cooking the meat in the oven at a high temperature of 400°F. This method creates a delicious, golden-brown crust on the outside of the meat while the inside remains juicy and tender. Roasting is ideal for larger cuts of pork tenderloin and can take between 25-35 minutes depending on the size of the roast.

Grilling is another popular method for cooking pork tenderloin. It’s a quick and easy way to cook the meat and gives it a smoky flavor. The key to grilling pork tenderloin is to make sure that the grill is super-hot before placing the meat on it. It’s recommended to grill the meat for 18-20 minutes per pound, depending on your fuel and how hot you can get the grill.

Baking is a simple method that involves cooking the meat in the oven at a lower temperature of 350°F. This method is ideal for smaller cuts of pork tenderloin and can take between 25-30 minutes depending on the size of the roast. It’s important to note that the internal temperature of the pork should reach 145°F before you can safely eat it.

Slow cooking is another method that involves cooking the meat in a slow cooker or crockpot. This method is ideal for busy cooks who want to prepare dinner ahead of time. Slow cooking pork tenderloin can take between 4-6 hours depending on the size of the roast.

Air frying is a newer method that has gained popularity in recent years. This method involves using hot air to cook the meat and results in a crispy exterior while keeping the interior juicy and tender. Cooking times for pork tenderloin in an air fryer vary depending on the size of the cut. For a small tenderloin, cook it at 400°F for 15-20 minutes. If you’re cooking a larger piece of pork tenderloin, increase the temperature to 425°F and cook it for 25-30 minutes or until its internal temperature reaches 145°F.

Oven Temperature And Cooking Time

To achieve the perfect pork tenderloin, it’s essential to roast it at the right temperature. Roasting meat below 400°F will cause it to dry out, as the low temperature won’t allow the pork to properly sear. Therefore, it’s recommended to roast pork tenderloin at 400°F, which will create a delicious, golden-brown crust on the outside of the meat while keeping the inside juicy and tender.

The cooking time for pork tenderloin depends on its weight, and as mentioned earlier, it’s 25 minutes per pound. For instance, if you have a 1-pound tenderloin, you’ll cook it for 25 minutes, and if you have a 2-pound roast, you’ll cook it for 50 minutes. It’s important to note that these are general guidelines, and the cooking time may vary depending on your oven and the thickness of the meat.

When cooking pork tenderloin, it’s crucial to check its internal temperature to avoid overcooking or undercooking. Use a meat thermometer to check the internal temperature of the pork before taking it out of the oven. The USDA recommends cooking pork to an internal temperature of 145°F, which is safe to eat and results in a juicy and flavorful roast.

If you prefer your pork tenderloin well-done, you can increase the cooking time by a few minutes. For example, adding 2-3 minutes per pound means that the internal temperature will be around 160°F when done. However, be careful not to overcook the meat as it can become dry and tough.

Seasoning Pork Tenderloin

Seasoning your pork tenderloin is a crucial step in ensuring that it’s packed with flavor. There are many seasoning options available, but one popular method is to create a dry rub. To make a dry rub, mix together a combination of spices such as garlic powder, oregano, cumin, coriander, thyme, salt, chili powder, brown sugar, smoked paprika, black pepper, ground mustard, and dried parsley.

Once you’ve created your dry rub, sprinkle it over the tenderloin with a dry hand and then rub it into the meat on both sides. Press gently to ensure that the seasoning adheres well to the tenderloin. You can also marinate your pork tenderloin in Italian dressing for 12-24 hours before cooking it.

When cooking your seasoned pork tenderloin, start by searing it in a large skillet over medium-high heat for about 10 minutes on each side. Then transfer the meat to a roasting pan and bake it in the oven at 400°F for 20-35 minutes until it’s browned and crispy on the outside and cooked through to your desired doneness.

Remember to use a meat thermometer to check the internal temperature of the pork before taking it out of the oven. The USDA recommends cooking pork to an internal temperature of 145°F for safe consumption. By seasoning your pork tenderloin properly and cooking it to perfection, you’ll have a delicious and flavorful meal that everyone will enjoy.

Using A Meat Thermometer

Using a meat thermometer is the best way to ensure that your pork tenderloin is cooked to perfection. A meat thermometer takes the guesswork out of cooking and helps you achieve accurate temperature readings. It’s also a safe way to cook pork and prevent your guests from getting sick.

To use a meat thermometer, insert the probe into the thickest part of the pork tenderloin, making sure not to touch any bones. Wait a few seconds for the temperature reading to stabilize, then check the temperature on the thermometer display. As mentioned earlier, the internal temperature of pork should reach 145°F.

If the temperature reading is below 145°F, continue cooking your pork tenderloin until it reaches the desired temperature. If you prefer your pork to be well-done, you can increase the cooking time by a few minutes per pound. However, remember that overcooking can dry out your pork tenderloin, so be careful not to overdo it.

A digital or instant-read thermometer is recommended for accurate temperature readings. These types of thermometers are affordable and easy to use. You can also use an oven-safe probe thermometer for perfect temperature readings in your roast.
