How to Reheat a Pre-Cooked Spiral Cut Ham

Hams come from the hind leg of a hog and have a high amount of protein. Precooked hams are available with or without the bone. When a ham is precooked, it's easily reheated in the oven safely. Precooked hams cut out the time required to cook a ham. The spiral sliced ham is also easier to serve, as it saves the time ordinarily spent slicing.

Inspect the package on the ham. Look for the weight and any specific cooking directions. Thaw a frozen precooked ham in the refrigerator at least 36 to 48 hours before you plan to cook the ham.

Preheat the oven to 162 degrees C. Remove the ham from the package and remove any netting around the ham.

Coat the bottom of the ham with non-stick cooking spray. Place the ham in a baking dish large enough to accommodate it.

Insert a meat thermometer into the ham. A precooked ham needs to reach an internal temperature of 60 degrees C.

Cover the ham with aluminium foil and place it in the oven. The time it takes to reheat the ham will depend on its size. For best results, reheat the ham 10 minutes for each pound.


Do not cook a precooked ham longer than 2 hours in the oven and avoid setting the temperature below 162 degrees C. This will prevent bacteria from growing.
