Follow this simple recipe for a tender, juicy pork loin roast cooked perfectly in the oven, complete with instructions for a quick pan sauce.

Ingredients

Scale
  • 1 (3 to 4 pound) pork loin roast, bone-out
  • 1 tablespoon olive oil
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon dried thyme
  • 1 cup chicken broth (for pan sauce)
  • 1 tablespoon cornstarch mixed with 2 tablespoons cold water (for pan sauce slurry)

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit.
  2. Pat the pork loin roast completely 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 entire surface of the pork loin roast evenly with the olive oil, then sprinkle and press the seasoning mixture onto the meat.
  5. Place the seasoned pork loin roast in a roasting pan or a large oven-safe skillet.
  6. Roast at 400 degrees Fahrenheit for 15 minutes.
  7. Reduce the oven temperature to 350 degrees Fahrenheit and 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 15 to 20 minutes per pound.
  8. Remove the pork loin roast from the oven when it reaches 145 degrees Fahrenheit.
  9. Transfer the roast to a cutting board, tent it loosely with foil, and let it rest for at least 10 minutes before slicing. This resting time is key for a juicy pork loin.
  10. While the pork rests, make the pan sauce: Place the roasting pan over medium heat on the stovetop. Scrape up any browned bits from the bottom of the pan.
  11. Pour in the chicken broth and bring to a simmer, stirring well.
  12. Whisk in the cornstarch slurry and cook until the sauce thickens slightly, about 1 to 2 minutes.
  13. Slice the rested pork loin roast against the grain and serve immediately with the pan sauce gravy.

Notes

  • For the best results, use a reliable meat thermometer to check the pork loin internal temp; 145 degrees Fahrenheit is the safe target for doneness.
  • If you prefer a stronger crust, sear the roast on all sides in a hot, oiled skillet before placing it in the oven.
  • This recipe works well for a weeknight dinner or a Sunday roast.
