Smoked hams come from the store fully cooked and ready to eat right out of the package. Here's how to heat it up easily and enjoy.
Preheat the oven to 325 degrees Fahrenheit.
Remove all packaging from the ham.
Place the ham in an oven-safe pan or dish and place in the oven.
Calculate the cooking time: Multiply the weight of the ham (in pounds) by 10, and that's how many minutes you need to heat it to a safe internal temperature of 140 degrees Fahrenheit.
Check the temperature of the ham after the calculated heating time has passed. Once the thermometer reads 140 degrees Fahrenheit, the smoked ham is warmed through and ready to eat.
If you need to heat the smoked ham in a hurry, you can raise the oven temperature higher than 325 degrees Fahrenheit. Though it will cook faster, the potential for the ham to dry out is also greater. Keep an eye on it so it doesn't go dry.
If the smoked ham was pre-sliced, wrap the entire ham in foil before placing it in the oven to help keep the moisture in the ham.
If you bought the ham from a source that does not conduct USDA inspections, you should heat the ham to an internal temperature of 165 degrees Fahrenheit instead of 140. This is to ensure that possible food-borne bacteria are destroyed and the ham is safe to eat.
