How are Pork Tenderloin and Pork Loins Different?

There’s a few things to think about when making roast pork tenderloin vs pork loins. Don’t confuse these two cuts. They vary in size and thickness. So you’ll have to be flexible and adjust cooking times depending on the size of the pork.

  • Tenderloins are thinner and more tender, thus the “tender”. They cook quicker than regular pork loins. They are usually also smaller, ranging from 1-2 pounds.
  • Pork loins are thicker and often times more lean, thus resulting in a tougher cut of meat if you overcook it.
  • Cooking times will vary greatly, particularly if you bought the tenderloin, which cooks much faster. So cook your loin roast longer if it’s large or thick. If you’re cooking with pork tenderloin, then the cooking times will be quicker.
  • If you are unsure on how long to cook your roast, cook the pork loin until it reaches an internal temperature of 145°F in its thickest part.
  • Hope you enjoy our oven roast pork loin recipe with your family. It’s a great dish when paired with simple veggies or even a backed potato! More Oven Roast Recipes, Soup and Stew Recipes, Appetizer Recipes

Yield: 8 serving
Prep Time: 5 minutes

Total Time: 1 hour 30 minutes
Pork loins can also vary in size and thickness. You can also use a pork tenderloin for this recipe, but it will cook quicker. Cooking times will vary depending on the size of the pork loin, particularly if you bought the tenderloin, which usually cooks faster. For best doneness, cook the pork loin until it reaches an internal temperature of 140°F in its thickest part. As it rests it will still continue to cook and should reach an ideal internal temperature of 145°F. The higher the temperature, the drier the loin will be, so don't go past 140°F while in the oven too much if possible.

Equipment

Instructions 

  • Preheat oven to 350°F/175°C. Rinse and pat dry pork loin, and then season with salt and pepper.
    Seasoning pork loin
  • ROAST THE PORK LOIN: Heat a large oven-safe skillet on medium-high heat. Add 2 Tablespoons of oil and then sear the pork loin on all sides, about 1 minute per side.
    Searing pork loin
  • Remove pork loin from the pan and set it aside. Coat the pork loin with dried herbs by patting it onto the loin.
    Herbs to pork loin
  • Turn off heat and remove pan from the heat. In same hot pan add 6 Tablespoons of butter, minced garlic, 2 Tablespoons Worcestershire sauce, and 2 teaspoons mustard. Stir the sauce until the butter is completely melted (if needed put the pan on the heat a bit to melt the butter completely).
    Making sauce
  • Place the pork loin back in the skillet and spoon some sauce over the pork loin.
    Spooning sauce over pork
  • Cover the pork loin with foil.
    Cover pork with foil
  • Roast the covered pork loin at 350°F/175°C for 30 minutes. Remove foil, spoon some more sauce over the loin.
    Basting pork
  • Continue to roast the uncovered pork loin at 350°F/175°C for another 25-35 minutes or until the interior temperature reaches 140°F/60°C.
    Testing pork temp
  • Remove from oven and take the pork loin from the skillet and cover the pork with foil to let it rest for about 10-15 minutes (make the gravy while the pork is resting). (Don't clean the skillet, you'll need it for the next step in making the gravy.)
    Removing pork from pan
  • MAKE THE GRAVY: Heat the same skillet with the pork drippings on medium-high heat. Skim off any crust chunks in the drippings. Add diced onions and cook until golden and caramelized, about 3-5 minutes.
    Caramelizing onions
  • Whisk in the 1/4 cup flour, whisking to remove lumps. Gradually whisk in the 2 cups of broth until incorporated and well combined. Season with salt and pepper, to taste (the saltiness and flavors will concentrate some when it reduces down).
    Whisking in broth
  • Reduce heat to medium, stirring often, simmer until thickened, about 5 minutes depending on your preferred thickness. Check for seasoning and salt again if needed.
    Thickening gravy
  • Slice pork loin and serve hot with the onion gravy.

Notes

Recipe Note: If you don’t have an oven-safe skillet, the pork loin can be seared on the stovetop on whatever skillet you do have, and then finished in an oven-safe baking dish. It just leaves you with another dish to wash.
