Oven Baked Pork Tenderloin

Baked pork tenderloin is such a great, family-friendly alternative to the regular chicken dinner! This is definitely one of those win-win meals: the pre-marinated meat makes the prep just a bit easier, and the cleanup is a breeze! I've paired the pork with baby red potatoes, carrots, and onion, as well as garlic and fresh herbs, for a sheet pan dinner that keeps weeknights simple and stress-free.

The Difference Between Pork Tenderloin and Pork Loin

Pork tenderloin, a smaller cut that generally weighs about 1 pound, does not come from the same part of the pig as the larger pork loin. Since pork tenderloin is naturally lean and tender, it does well when cooked quickly at high temperatures. By contrast, pork loin lends itself well to slower roasting or grilling techniques. For more details about these two different cuts of meat, check out this article. Today, we're focused only on the pork tenderloin!

Ingredients for Sheet Pan Pork Tenderloin

This is just a quick overview of the ingredients that you'll need for a sheet pan full of baked pork tenderloin and vegetables. As always, specific measurements and step-by-step cooking instructions are included in the printable recipe box at the bottom of the post.

Olive oil: to coat the potatoes and veggies, which helps them brown in the oven, adds flavor to the dish, and prevents the ingredients from sticking to the pan.
Pork tenderloin: I'm using a roasted garlic and herb marinated pork tenderloin made by Smithfield for a shortcut, but I've also included notes below if you'd prefer to start with a plain pork tenderloin that you marinate yourself at home. Throw two pork tenderloins onto the sheet pan if you're feeding a larger family.
Baby red potatoes: or use other small potatoes (such as baby Gold potatoes), which you don't even need to peel. Just cut them into halves or quarters (depending on their size), and toss them with the rest of the ingredients.
Carrots: peeled and chopped into ¾-inch chunks.
Garlic: for savory flavor on the veggies and potatoes that pairs with the flavors in the pork marinade.
Rosemary and thyme: fresh herbs are always my preference, but you can substitute with smaller amounts of dried herbs when necessary.
Kosher salt and ground black pepper: to enhance the other flavors in the dish.

How to Bake Pork Tenderloin

This easy dinner comes together on one tray for a simple weeknight meal with minimal clean-up!

Pat the marinated pork dry with paper towels.
Place the pork tenderloin in the center of a large rimmed baking sheet that's been greased with olive oil.
Toss together the potatoes, carrots, onion, garlic, olive oil, rosemary, thyme, salt, and pepper in a large mixing bowl or Ziploc bag.
Spread the vegetables in a single layer around the pork on the outer edges of the baking sheet.
Bake the pork and vegetables in a 425°F oven until the meat is cooked through and the vegetables are tender, flipping the tenderloin over halfway through, about 25-30 minutes.
Let the pork rest for 5-10 minutes before slicing and serving with the potatoes and vegetables.

How Long to Bake Pork Tenderloin

This pork tenderloin dinner roasts in the oven at 425°F for about 25-30 minutes; however, the total baking time will vary depending on your individual oven, the type of pan that you use, and the size and temperature of your pork. Larger tenderloins may require up to 35 minutes to cook through.

How to Make Pork Tenderloin Juicy

Not overcooking the meat is the key to preventing the pork tenderloin from drying out. Since this particular cut of meat is already very tender and lean, it does best when cooked quickly at a high temperature (by contrast, a tougher, fattier cut like a pork shoulder does best when cooked low and slow). If you roast the tenderloin at a low temperature or for too long, you risk drying out the meat, resulting in a tougher, chewier texture. For a juicy pork tenderloin, you're looking for a medium finish (about 145°F when a meat thermometer is inserted into the thickest part of the meat).

How to Know When Pork Tenderloin is Done

Total cooking time will vary depending on the size, thickness, and temperature of your pork when it goes into the oven. As a result, I always recommend using a meat thermometer to know when your pork is done. The tenderloin is ready to come out of the oven when it reaches an internal temperature of 140-150°F. The temperature will continue to rise as it rests, and you want to make sure that you don’t overcook the meat (because it can become dry).

Anywhere between 140°F and 160°F is fine; however, cooking it more towards medium (145°F) will produce juicier pork. Always rest the meat for at least 5-10 minutes before slicing and serving.

What color is cooked pork tenderloin?

According to the National Pork Board, it's perfectly safe to consume medium pork (that's cooked to about 145°F). At this stage, the pork will have a slight touch of pink in the center and will be at its juiciest!

Serving Suggestions

You don't need to add anything to this meal, since you've got the meat, potatoes, and veggies all on one tray. That said, here are some of our favorite pork tenderloin sides if you'd like to round out the supper with a bread basket or extra options:

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days or in the freezer for up to 2 months. Sliced tenderloin is delicious on a sandwich the next day!

How to Reheat

Place the pork on a sheet pan and warm in a 325°F oven just until heated through (about 10-15 minutes). Be careful not to overheat, or the tenderloin will become dry. You can also reheat individual portions of pork in the microwave for 1-2 minutes.

Recipe Variations

If you don't have (or can't find) a pre-marinated roasted garlic and herb pork tenderloin, you can substitute with a regular pork tenderloin. Just marinate the pork at home by placing the tenderloin in a zip-top bag or shallow dish with your favorite Italian salad dressing (homemade or from a bottle!). Whisk together this honey garlic dijon mustard marinade, or pick up a bottle of Ken's Steakhouse Lite Northern Italian dressing. Really, anything similar will work. You can marinate your pork for up to 24 hours in the refrigerator before using it in the recipe.
A single pork tenderloin is typically about 1 lb. of meat, making it an appropriate amount of food for 2-4 people (depending on the size of your appetite). If you’re feeding a larger family of 4-5, I recommend placing two pork tenderloins on one baking sheet and the vegetables on another baking sheet. Just make sure that you leave space in between the two pieces of meat to allow the heat to circulate.
Season the potatoes and veggies with just about any herbs and spices that you enjoy. Other good options include parsley, chives, basil, oregano, garlic powder, onion powder, cumin, and paprika. This homemade all-purpose seasoning blend also works really well!
Searing the tenderloin in a skillet can add color and flavor to the pork, and can also help to lock in some juices. It's not necessary since the high heat of the oven browns the meat as it bakes, but if you choose to take this extra step before baking, you'll need to reduce the pork's total time in the oven.

Tips for the Best Baked Pork Tenderloin Recipe

Allow the pork to sit on the counter and come to room temperature for about 30 minutes before roasting. This will help the meat cook evenly.
The total cooking time may vary, depending on the size, thickness, and temperature of your pork when it goes in the oven. As a result, use a meat thermometer to know exactly when your pork reaches the desired level of doneness. Some tenderloin requires just 25 minutes, while others might need up to 35 minutes.
Let the pork rest for at least 5-10 minutes before slicing and serving. This will give the juices a chance to redistribute so that your meat is as juicy as possible.
Pork tenderloin is a healthy option for most diets. The extra-lean meat is high in protein and a rich source of B vitamins and selenium. One 4-ounce serving of pork tenderloin has almost 24 grams of protein, 0 carbohydrates, less than 4 grams of fat, and just 136 calories. The American Heart Association has certified pork tenderloin as a heart healthy food, so eat up and enjoy!
