Once a ham is cooked, the leftovers can be stored in the refrigerator for up to four days before they start to go bad. Baked ham can be stored in the freezer for up to six months.
If baked ham leftovers cannot be used within four or five days, it is best to freeze it. To prepare cooked ham for freezing, remove all the meat from the bone. Chop up the meat into bite-size pieces and place in several freezer bags, dividing the ham into portion sizes. When ready to use the frozen ham, thaw out as many portions as are needed.
