Make a tender and juicy pork loin roast using simple ingredients. This recipe provides clear oven timing and temperature guidance for a perfect Sunday roast or easy weeknight dinner.

Ingredients

Scale
  • 3 lb pork loin roast, bone-out
  • 2 tablespoons olive oil
  • 1 tablespoon kosher salt
  • 1 teaspoon black pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon dried thyme

Instructions

  1. Preheat your oven to 400°F (200°C).
  2. Pat the pork loin roast dry with paper towels. This helps create a good crust.
  3. In a small bowl, mix the kosher salt, black pepper, garlic powder, and dried thyme.
  4. Rub the olive oil all over the pork loin roast.
  5. Sprinkle the seasoning mixture evenly over the entire surface of the pork.
  6. Place the roast in a roasting pan or on a rimmed baking sheet.
  7. Roast at 400°F (200°C) for 15 minutes.
  8. Reduce the oven temperature to 350°F (175°C) and continue roasting until the internal temperature reaches 145°F (63°C) on a meat thermometer, about 15 to 20 minutes per pound total cooking time.
  9. Remove the pork loin roast from the oven when it reaches 145°F (63°C) internal temperature.
  10. Tent the roast loosely with foil and let it rest for 10 to 15 minutes before slicing. This resting period is key for a juicy pork loin.
  11. Slice against the grain and serve. Make a simple pan sauce gravy with the drippings if desired.

Notes

  • For the juiciest pork loin, use a meat thermometer to check the pork loin internal temp. 145°F is the safe target.
  • If you want a pan sauce gravy, place the roasting pan on the stovetop over medium heat after removing the roast. Scrape up any browned bits, add a splash of broth or water, and let it reduce slightly. Thicken with a slurry of cornstarch and water if needed.
  • This recipe works well for an easy pork dinner or a traditional Sunday roast recipe.
