This delicious pork loin roast starts with a simple herb and spice rub and then it is slow cooked to perfection with a tangy sauce mixture. The sauce is thickened and served with the pork. Serve the roast with mashed or boiled potatoes for a fabulous meal. Or serve it with rice or noodles.

The pork roast is done after about 3 hours on high or about 6 to 8 hours on low. To avoid overcooking the pork, check the temperature with an instant-read thermometer. The minimum safe temperature for pork is 145 F/63 C. If overcooked, the pork can become dry and could be difficult to slice. Adding a large, sliced onion can amplify the flavor in the dish.

You can skip the searing step, but I think the caramelization adds some excellent flavor.


  • 1 boneless pork loin roast (about 3 pounds)
  • 1 teaspoon garlic powder
  • 1 teaspoon dried leaf thyme
  • 1 teaspoon paprika
  • 1/2 teaspoon freshly ground black pepper
  • 1/2 teaspoon Kosher salt
  • 2 tablespoons olive oil
  • 1 1/2 cups chicken stock (low-sodium or salt-free)
  • 1/2 lemon (juiced, about 1 1/2 tablespoons)
  • 1 tablespoon soy sauce
  • 1 teaspoon Worcestershire sauce
  • 2 tablespoons cornstarch
  • 1 tablespoon water (cold)

Steps to Make It

  1. Gather the ingredients.

  9. Cover and cook on LOW for 6 to 8 hours or on HIGH for about 3 hours. Check the roast at the lower time for doneness to avoid overcooking. An instant-read thermometer should register at least 145 F/63 C.

  10. Remove the roast to a platter, tent with foil, and keep warm.

  11. Pour the liquids into a gravy separator, and they pour them into a medium saucepan. Bring to a boil. Taste and adjust the seasonings. If the liquids are very watery from the long cooking time, boil for a few minutes to reduce and concentrate the flavors.

  12. Put the 2 tablespoons of cornstarch in a small cup or bowl and whisk with about 1 tablespoon of cold water. Whisk the cornstarch mixture into the simmering liquids and continue cooking, stirring, until the sauce is thickened.

  • The USDA recommends a minimum safe temperature of 145 F. Check the pork with a reliable instant-read thermometer to ensure it is completely cooked.

Recipe Variation

  • Slice a large onion and add it to the slow cooker before you add the pork. Or add it to the skillet as you sear the pork and transfer to the slow cooker along with the roast.
