Wash the sweet potato and scrub off any dirt from the skin. No need to dry it, as the moisture helps cook it. But, make sure it’s not DRIPPING wet.
Use a fork to prick holes at least ¼ inch deep ALL over the sweet potato. Pretty much exactly like you do with a baked potato.
Put your potatoes in the bottom of your slow cooker and put on the lid
Cook them until they’re perfectly tender which is 6-8 hours on low or 3-4 hours on high, depending on the size of your potato, as well as your slow cooker.
