Cooking Tender Pork Tenderloin in the Oven – Step-By-Step Guide

This is the fun part. It’s a simple process. All you have to do is follow it step by step.

  • Switch on your oven.
  • Let it reach a temperature of 176 degrees Celsius.
  • At this point, you must have seasoned your pork tenderloin with the seasoning mix.
  • Pour the recommended quantity of olive oil into your cast-iron skillet. I recommend a large skillet that can be used in the oven safely. If you don’t have a skillet, don’t sweat it. A baking dish will do just fine.
  • Once your oil is heated, transfer your pork tenderloin to it. Pan-sear it on all sides for about 3 minutes for each side or till it’s browned.
  • Now, put the skillet with the meat in the oven and let it cook for roughly 30 minutes or till the internal temperature is 63 degrees Celsius. You can check your roasted pork tenderloin using a meat thermometer to be sure.
  • Once it’s ready, take it out of the oven and let the pork rest for at least 5 minutes. The reason is to let the pan juices move around, tenderizing the meat in the process.
  • After 5-10 minutes, slice your easy-baked pork tenderloin into pork chops and serve with vegetable toppings or anything you prefer. Bon appetit!

Pork Tenderloin vs. Pork Loin

You thought you were the same? I thought so too. But guess what? They’re different cuts of meat. For the benefit of those who don’t know the difference, I’ll briefly explain. The pork tenderloin is that boneless piece of meat sourced from the muscle that runs along the pig’s backbone. It’s long and narrow in form.

On the other hand, the pork loin comes from the back of the pig and can be boneless or with bone. In contrast to the tenderloin, the pork loin is flatter and wider in form. Just like pork tenderloin, air-fried or roasted pork loin depends on your preferred cooking method. If you like pork tenderloin then you’re going to love our recipe for delicious home made pork chops.

Pork Tenderloin Cooking Temp

Though I’ve mentioned this before, it can’t be overemphasized that the ideal cooking temperature for cooking pork tenderloin is 63 degrees Celsius. This is the standard according to USDA. The reason it’s important for you to stick to this temperature when cooking is for health purposes. If your pork is undercooked, it won’t be safe to eat because the microorganisms present in the meat won’t be neutralized. This means that consuming undercooked meat is a straight invitation of these harmful organisms into your body system.

Point to note: To properly use the meat thermometer, stick it in the thickest part of the pork tenderloins. If that part reaches the desired internal temperature, your meat is ready to be removed from the heat. Also, if you’re someone who loves pork as much as I do, then you’ll want to know the best way to reheat pork after you’ve cooked it.

Reheating Pork Tenderloin

Even if you intend to serve leftover pork, they can still make a great meal. There are multiple ways to reheat your pork tenderloin:

  • Microwaving: Alright, let’s get to microwave your meat! Grab a dish that’s safe for the microwave, preferably in ceramic (we don’t want any meltdowns!). Pop your meat inside, cover it up with a damp towel, and slide it into the microwave. Now, crank it up to high power and let it go for 30-second intervals, around 2 minutes in total. That’s when your meat will be heated to perfection!
  • Baking in the Oven: Now, we’re talking about some real slow-cooking business. Fire up your oven and wait for it to reach that sweet spot of 350 degrees F (or 176 degrees Celsius). Grab a baking dish and nestle your pork tenderloin nice and snug. Cover it up with some foil to keep the flavors locked in. Slide that dish with the meaty goodness into the oven and let it work its magic for about 15 minutes. Once time’s up, get ready to enjoy your perfectly baked tenderloin.
  • Using a stovetop: Time to work on those skillet skills! Grab a large skillet and pour in some oil. Get that bad boy nice and heat over medium heat. Once the oil sizzles and dances around, it’s showtime for your meat. Toss that meat into the skillet, and let each side cook for a solid 7 minutes. Flip it, watch it sizzle, and you’re on your way to a scrumptious meal.

Hacks For Cooking Pork Tenderloin

If you want to cook the best pork tenderloin, there are certain helpful tips that you should keep in mind:

Remove The Silver Skin

It’s important to do this before cooking the pork tenderloin. The silver skin is the sinew layer of the meat’s exterior. Cooking the pork tenderloin with the silver skin on is not advisable because it doesn’t get tender. To remove the silver skin, get a sharp knife, put it beneath the sinew, and slowly cut it off. Be careful while doing this so that you don’t remove a significant amount of meat in the process.

Immerse The Pork Tenderloin In Brine

If you want to enhance or boost the flavor of your pork tenderloin, mix four cups of water with the same amount of tablespoons of kosher salt. Now, sink your meat in this solution, preferably in a ziplock bag or a large bowl. Put it in your fridge and leave it for at least 30 minutes. However, you can leave the meat immersed for as long as 2 hours. This will make your meat juicier. After the time has passed, take out the meat and pat it dry. Then, throw the brine solution away.

How Can I Prevent Pork Tenderloin From Drying Out?

The simple answer will be – by not overcooking it. To avoid this, make sure you set the dial of the oven to the right temperature setting and let it cook within the recommended duration, which I’ve already mentioned earlier. If the dial is set to a temperature that’s slightly above the recommended range, make up for it by shortening the cooking duration by a few minutes. If all these seem complicated, the simple hack to this is checking if the internal temperature of the meat is 63 degrees Celsius before removing it from the oven.

Can Pork Tenderloin Go Bad In The Freezer?

Yes, it can if you store it too long. Now, how long is too long? If your pork is in the freezer for more than a year, especially if it isn’t stored properly, it will go bad in the freezer.
