With a precooked ham, the purpose of cooking is to heat the meat through while adding flavor. Because the meat is already cooked, over-cooking can leave your ham dry. A Crock Pot slowly cooks the ham and keeps the meat moist while infusing flavors, such as brown sugar or tropical fruits. With the addition of a few other ingredients, a Crock Pot allows you to cook the ham throughout the day, leaving your oven available for side dishes.
Place the precooked ham into the Crock Pot. If you have a half ham or spiral-cut ham, place the flat end of the ham down. Place the lid on top to ensure that there is enough room for the lid to seal. If the lid will not seal, trim the ham as needed.
Add enough liquid to create a 1-inch bath at the bottom of the Crock Pot. You can use water, cola or fruit juice. Add any fruits, spices or brown sugar you desire to the liquid or directly onto the ham.
Place the lid on the Crock Pot and cook for six to eight hours on the low setting or until the internal temperature of the precooked ham reaches 140 degrees Fahrenheit with a meat thermometer.
