Learn how to make a perfectly juicy pork loin roast using simple ingredients. This easy oven roast is great for a weeknight dinner or a Sunday roast, complete with tips for internal temperature and a simple pan sauce.

Ingredients

Scale
  • 3 lb pork loin roast, trimmed
  • 1 tablespoon olive oil
  • 1 teaspoon salt
  • 1 teaspoon black pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon dried thyme
  • 1/2 teaspoon paprika

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit.
  2. Pat the pork loin roast dry with paper towels. This helps create a nice crust.
  3. In a small bowl, mix together the salt, pepper, garlic powder, thyme, and paprika.
  4. Rub the olive oil all over the pork loin roast.
  5. Sprinkle the spice mixture evenly over the entire surface of the roast, pressing gently so it sticks.
  6. Place the seasoned pork loin roast in a roasting pan or on a rimmed baking sheet.
  7. Roast for 15 minutes at 400 degrees Fahrenheit.
  8. Reduce the oven temperature to 350 degrees Fahrenheit. Continue roasting until the internal temperature reaches 145 degrees Fahrenheit on a meat thermometer, which usually takes about 15 to 20 minutes per pound.
  9. Remove the pork loin roast from the oven immediately when it hits 145 degrees Fahrenheit.
  10. Transfer the roast to a cutting board and tent it loosely with foil. Let it rest for at least 10 to 15 minutes before slicing. This resting time is key for a juicy pork loin.
  11. While the pork rests, make a quick pan sauce gravy by deglazing the roasting pan with a splash of broth or wine, scraping up the browned bits, and simmering until slightly reduced.
  12. Slice the roast against the grain and serve with the pan sauce.

Notes

  • For the juiciest pork loin, always use a meat thermometer. 145 degrees Fahrenheit is the target internal temperature.
  • If you want a deeper crust, you can sear the roast in a hot, oven-safe skillet with oil for 2-3 minutes per side before putting it in the oven.
  • This recipe works well for a simple Sunday roast or a quick weeknight dinner.
