A HoneyBaked ham is pre-cooked and requires reheating in the oven at 275 degrees Fahrenheit for 10 minutes per pound. HoneyBaked recommends heating only the slices needed for immediate use rather than the entire ham, when possible. The company also suggests the use of a skillet to reheat selected slices.
Due to the pre-cooked nature of a HoneyBaked ham, additional cooking is unnecessary, and the company suggests serving it directly from the refrigerator. When reheating the entire ham, cover it with foil, and place a small, water-filled pan on the rack below the ham to retain moisture. To heat selected slices in the oven, wrap the slices in foil before placing them in the oven.
