This delicious pork loin roast starts with a simple herb and spice rub and is then 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. It's also perfect alongside 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. If overcooked, the pork can become dry and could be difficult to slice. Additionally, you can skip the searing step, but the caramelization adds an excellent flavor.

  • 1 boneless pork loin roast, about 3 pounds

  • 1 teaspoon garlic powder

  • 1 teaspoon dried thyme

  • 1 teaspoon paprika

  • 1/2 teaspoon freshly ground black pepper

  • 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 cold water

  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, then 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.

Tip

  • 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.

Can you overcook pork loin roast in a crock pot?

It is best to cook this lean cut of meat on low and slow rather than on high. The high setting can cook it too fast and tends to boil it. Pork loin roast can be overcooked and will become dried out, even in the crock pot.
