Knowing how to properly reheat your ham makes all the difference in not ending up with a dried out, unappealing piece of meat. How you reheat ham depends on the type of ham you are reheating. Hams either come uncooked of fully cooked. If you are reheating a fully cooked product, the heating requirements are lower, but even if the ham is already cooked, cook the ham to a higher temperature if it was uncooked when you purchased it to cook it to a safe temperature level. With the proper reheating method, the end result is a fully cooked, moist piece of ham.
Preheat your oven to 163 degrees Celsius.
Place the leftover ham pieces or slices in an oven-safe cooking dish.
Cover the dish with aluminium foil to seal in moisture and prevent the ham from drying out.
Place the dish in the oven.
Check the ham about every 10 minutes. Insert a meat thermometer into the middle of a couple pieces of ham. The ham is ready when it registers 60 degrees Celsius for previously packaged fully cooked ham or 73.9 degrees Celsius for fully cooked leftover ham.
