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.

I added a large sliced onion when I made this recipe. See the tips and variations for some optional ingredients and substitutions. 

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

  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.

Tips

  • 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 Variations

  • 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.
