Ingredients

Scale
  • 3 lb pork loin roast, bone out
  • 1 tablespoon olive oil
  • 1 teaspoon 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.
  3. In a small bowl, mix the salt, pepper, garlic powder, and thyme.
  4. Rub the olive oil over the entire surface of the pork loin.
  5. Sprinkle the seasoning mixture evenly over the pork loin, pressing lightly so it adheres.
  6. Place the seasoned 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 325 degrees Fahrenheit. Continue roasting until the internal temperature reaches 145 degrees Fahrenheit on a meat thermometer, about 15 to 20 minutes per pound total cooking time.
  9. Remove the roast from the oven when it reaches 145 degrees Fahrenheit.
  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 result.
  11. Slice against the grain and serve immediately.

Notes

  • For a simple pan sauce, place the roasting pan on the stovetop over medium heat. Scrape up any browned bits from the bottom of the pan. Add 1 cup of chicken broth and bring to a simmer, reducing slightly until thickened, or whisk in 1 tablespoon of cornstarch mixed with 2 tablespoons of cold water to create a quick gravy.
  • If you prefer a slightly crisper exterior, you can sear the roast in an oven-safe skillet on the stovetop over medium-high heat for 2 minutes per side before placing it in the oven.
