It is safe to bake fully cooked ham with the assistance of children as long as adequate precautions are taken and parents supervise the process. Parents should instruct children about safety guidelines in advance so that baking can be fun.
Bake a fully cooked ham to reheat it without drying it out. Place the ham on a rack in an oven, add water to the bottom of the pan, and cover it with foil. Bake it at 325 degrees Fahrenheit for around 20 minutes per pound until the meat thermometer reaches 140 degrees Fahrenheit. To make a glazed ham, remove the foil, apply the glaze, and let it bake at 400 degrees Fahrenheit for an additional 15 minutes. Warn children of the risk of burns, and make it a rule to use oven mitts when opening oven doors, using the range or handling pans.
