Lean and Tender Meat

It is exceptionally lean, making it a prime selection.

The absence of excess fat also allows the meat to absorb flavors from seasonings and marinades, enhancing its overall taste.

Making this perfect for busy weeknights or when you need to prepare a meal in a hurry. Its speedy cooking time makes it a reliable choice for those seeking a delicious and satisfying dinner without the long wait.

Things That Will Affect the Cooking Time of Pork

Weight and Size

The best way to make the perfect tenderloin is to check the weight. The weight and size of your pork tenderloin play a big role in how long it takes to cook. It’s a simple equation: the larger the tenderloin, the longer it needs to be in the oven, on the grill, or in the pan.

 If you’ve got a hefty one-pound tenderloin, it won’t cook as quickly as a smaller one. So, be sure to check the weight and size of your cut before you start cooking to get the timing right.

Cooking Temperature and Method

The cooking method and temperature you choose also impact the cooking time. If you’re roasting your pork tenderloin in a blazing hot oven, it’ll cook faster than if you’re using a lower temperature. For example, a high-heat roast might take around 15-20 minutes per pound, while a slower, lower-temperature roast could take closer to 25-30 minutes per pound. The same goes for grilling or pan-searing; hotter and faster or slower and lower, it all makes a difference.

Initial Temperature Before Cooking

The starting temperature of your pork tenderloin is another piece of the puzzle. If your meat is ice-cold from the fridge, it’ll take longer to cook through compared to a tenderloin that’s been brought closer to room temperature. So, if you’re in a rush, take your pork out of the fridge a little ahead of time to give it a head start.

Let’s explore how to make the best pork tenderloin no matter what method or seasoning you are using.

How Long to Cook Pork Perfect Tenderloin Per Pound

How Long to Cook Pork Perfect Tenderloin Per Pound

To achieve a perfectly cooked pork tenderloin, you can follow the rule of thumb: cook it for approximately 15-20 minutes per pound at an oven temperature of around 375°F (190°C).

However, according to USDA guidelines,  it’s essential to use an internal meat thermometer to check for doneness, as the specific cooking time may vary depending on factors like the initial temperature of the meat and your chosen cooking method.

The target internal temperature for cooked pork tenderloin is 145°F (63°C) when inserted into the thickest part of the meat. When the tenderloin reaches this temperature, it is safe to eat, tender, and juicy. Allowing the meat to rest for a few minutes after cooking helps the juices redistribute and keeps the pork even more flavorful and succulent.

While the 15-20 minutes per pound guideline is a helpful starting point, always use a meat thermometer to ensure that your pork tenderloin is perfectly cooked, as actual cooking times may vary based on factors such as the size and initial temperature of the tenderloin, as well as the specific cooking method and equipment you’re using.

Pork Tenderloin Cooking Guidelines

Check the Weight

No matter what method you will be using to cook your pork, you can be assured perfect results if you know how much it weighs.

Let’s explore different ways to cook.

Oven-Roasting Method

Start by preheating your oven. This gets it nice and toasty, ready to work its magic. For pork tenderloin, the sweet spot temperature is around 375°F (190°C).

Season with your favorite flavors; a sprinkle of salt, a dash of black pepper, brown sugar, onion powder, garlic powder, or maybe some herbs or spices. You can even use a marinade for extra flavor.

Then, place it on a baking sheet, Dutch oven, or in a roasting pan.

As for how long to roast it, it depends on the weight. A rough estimate is about 20-25 minutes per pound. For best results, use an instant-read thermometer to check when it reaches an internal temperature of 145°F (63°C). That’s the magic number for perfectly cooked pork.

Once it’s out of the oven, resist the urge to dive in right away. Let your pork tenderloin rest for a few minutes. This resting time helps the juices redistribute, and it’ll be even more tender and flavorful when you slice it up.

Grilling Method

Fire up your grill and give it some time to heat up. You want a medium-high heat, around 400°F (200°C). Clean and oil the grates to prevent sticking. If you are new to grilling, we can help you with tips on How to Keep a Charcoal Grill Lit.

Set your charcoal grill up with the coals on one side. If you have a gas grill, turn the burners on one side on high and the other side on low.

Season and prepare the meat just like with the oven method. Just season your tenderloin with your chosen spices or marinade. Then, place it on the grill.

Next, sear the tenderloin over the high heat for 2 minutes per side to get beautiful grill marks. The side over the coals. You will get those gorgeous grill marks and seal in the juices.

Then move to the cooler side of the grill and finish cooking over indirect heat keeping the grill covered the whole time to keep the heat in. Cooking time will vary depending on the weight.

Grill your pork for about 15-20 minutes per pound, turning it occasionally. Use that trusty meat thermometer again to check for an internal temperature of 145°F (63°C).

Rest the pork before slicing and serving.

Stovetop and Pan-Searing Method

Heat a skillet or pan over medium-high heat. I like to use a sturdy skillet like a cast iron. Add a little oil to prevent sticking.

Season your tenderloin as usual, then place it in the hot pan.

Cooking Time and Temperature. For pan-searing, it’s a bit quicker; about 5-7 minutes per side, depending on the thickness. Use the meat thermometer to check that internal temperature of 145°F (63°C).

And that’s it!

Whether you’re roasting, grilling, or pan-searing, these simple steps ensure your pork tenderloin is cooked to perfection. Remember, the weight of your pork is your timer, and a meat thermometer is your best friend to avoid guesswork. Enjoy your delicious, juicy pork dinner!

What are Common Mistakes People Make When Cooking Pork?

Cooking pork can be a delicious endeavor, but there are common mistakes that people often make. Avoiding these errors will help you achieve perfectly cooked and safe pork dishes.


Overcooked pork becomes dry and tough. Use a meat thermometer to ensure you cook the pork to the recommended internal temperature (145°F or 63°C for pork tenderloin). Remember that the meat continues to cook while resting, so take it out just before it reaches the desired temperature.

Under Seasoning

Pork benefits from seasoning to enhance its flavor. Don’t forget to season with salt, pepper, and another spice rub with spices or herbs. A well-seasoned pork dish is more flavorful and satisfying.

Skipping Resting Time

Allowing your cooked pork to rest for a few minutes before slicing is crucial. Resting helps the juices redistribute, resulting in a juicier and more tender final product.

Not Using a Meat Thermometer

Relying solely on cooking times can lead to overcooking. Invest in a good meat thermometer to accurately monitor the internal temperature of the pork and ensure it’s safe to eat.

Inadequate Preparation

Not patting the pork dry before cooking or forgetting to rub it with oil can affect browning and overall texture. Properly dry with a paper towel and season the meat before cooking.

Using High Heat Continuously

While a high temperature is great for searing, using it for the entire cooking process can lead to burning or uneven cooking. Use moderate heat when roasting, grilling, or pan-searing.

Not Monitoring the Meat

Leaving the pork unattended while cooking can lead to overcooking or burning. Stay vigilant, especially when using high-heat cooking methods.

Using the Wrong Cut for the Cooking Method

Not all pork cuts are suitable for every cooking method. For example, pork tenderloin is great for roasting or grilling, while tougher cuts like pork shoulder are better for slow cooking.

By avoiding these common mistakes, you can ensure that your pork dishes turn out beautifully, whether you’re roasting, grilling, pan-searing, or slow-cooking this versatile and delicious meat.
