In many homes in America, pork gets a bad rap. It has an unearned reputation as an unhealthy and fatty protein to be avoided at all costs. But, in fact, several cuts of pork, including a pork loin and pork roast, have fewer calories with less fat and cholesterol than skinless chicken thighs.

The easy-to-make and delicious oven-roasted pork loin recipe below will show you that pork is not something you should fear but enjoy.

Get a Good Piece of Pork

Even the best pork roast recipe won’t leave you and your guests impressed if you don’t start with great ingredients. That means ensuring you buy a quality pork loin or pork roast.

When selecting a pork loin or roast, choose light red or darker pink. Avoid meat that is exceedingly pale or cuts with black spots on the fat. To ensure the highest freshness, cook the pork as soon as possible after purchase. If you must store the pork for longer than a few days, it is safer to stick it in the freezer.

Don’t Settle For Dried Out Pork Loin

Home cooks are often disappointed by the roast pork they prepare at home for one simple reason: Most pork loin recipes encourage overcooking the pork to avoid even the slightest hint of pink. But according to the USDA, pork is safe to eat as long as the interior temperature is 145 degrees before removing it from the oven. At that temperature, you may still notice a slightly pink interior.

Remember that once you remove your pork loin or roast from the oven, the internal temperature will rise 3 to 4 degrees. Always use a meat thermometer to check if a pork loin is your prepared temperature prior to slicing.

Hints for Getting the Best Flavor From This Boneless Pork Loin Roast Recipe

Follow these tips to take your oven-roasted pork loin to the next level.

  • Let the pork come up to room temperature before applying the rub. Give your roast about 15 to 20 minutes to shake off some of the fridge chill. As the pork warms up, it can become a bit damp. Use a paper towel to dry the meat completely and then evenly spread the rub over the entire surface.
  • Preheat your oven with the rimmed baking sheet and wire rack inside. You want everything hot before placing your roast on the wire rack. Heating your cookware will prevent cold metal from cooling down the oven and help stop the meat from sticking.
  • Remember to turn over the complete roast and rotate the pan 180 halfway through the cooking process. By doing this, you will allow the meat to cook more evenly. When you are testing for doneness, use the probe of the thermometer to measure the distance to the middle of the roast to ensure you get an accurate reading.

Pork Loin vs. Pork Tenderloin

The loin roast comes from the area of the pig between the shoulder and the beginning of the leg. You can purchase the pork loin with either the bone-in or boneless. I like to purchase the entire pork loin and then you can cut some of it into slices for boneless pork chops, and you can also make a roast from this meat.

Sometimes a loin roast is confused with a tenderloin. They are not the same, and the loin roast is sold in portions that weigh between two and four pounds. The tenderloin is smaller when compared to the pork loin, and it weighs only a pound.

There is also a large price difference between the two. The pork loin is a more budget-friendly cut of pork. The pork loin roast is a much more budget-friendly cut of pork.

How long should you cook a pork roast?

To cook the pork roast correctly, note how much the meat weighs. It takes approximately 25 minutes per pound at 350 degrees. The internal temperature of the pork roast should between 145 and 160 degrees. Do not overcook the pork, it will become dry. Also, make sure you allow the pork loin roast to rest for about 10 minutes before serving.

There is no need to cover the roast with foil or a lid while cooking; this is a dry roasting technique. When the roast finishes cooking, you may have some pan drippings that you will want to pour over the pork loin roast after it has finished cooking.

    This came out awesome. My roast was a little over 3lbs. I brought the roast to room temp & Cooked for 1 hour at 375. When I took it out of the oven I used a meat thermometer. It registered 160deg on the nose. Definitely rested and I had a beautiful juicy roast. It also looked perfect. The paste turned a gorgeous brown. Love a simple recipe that returns a delicious dish.
