Prepare a tender and juicy pork loin roast using simple ingredients and clear oven timing for a reliable weeknight dinner or Sunday roast.

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 degrees Fahrenheit.
  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 spice mixture evenly over the entire surface of the pork.
  6. Place the seasoned pork loin roast in a roasting pan or on a rimmed baking sheet.
  7. Roast at 400 degrees Fahrenheit for 15 minutes.
  8. Reduce the oven temperature to 350 degrees Fahrenheit. Continue roasting until the internal temperature reaches 145 degrees Fahrenheit on a meat thermometer inserted into the thickest part of the roast. This usually takes about 20 minutes per pound after the initial high-heat period.
  9. Remove the pork loin roast from the oven when it reaches 145 degrees Fahrenheit.
  10. Tent the roast loosely with foil and let it rest for at least 10 minutes before slicing. This resting period is key for a juicy pork loin.
  11. Slice against the grain and serve. You can make a simple pan sauce gravy using the drippings.

Notes

  • For a pan sauce gravy, place the roasting pan on the stovetop over medium heat. Scrape up any browned bits from the bottom of the pan. Whisk in 1 tablespoon of flour until smooth, then slowly whisk in 1 cup of broth. Simmer until thickened.
  • The target internal temperature for safe and tender pork is 145 degrees Fahrenheit followed by a rest.
  • If you prefer a slightly more browned exterior, you can sear the roast in an oven-safe skillet on the stovetop before placing it in the oven.
