What is pre-cooked ham?

A pre-cooked ham is a cut of pork that has been baked, smoked, or cured with salt to preserve it. This includes hams that you find in a deli or a grocery store that has been pre-sliced and sometimes fully cooked for your convenience.

Pre-cooked ham is often used as a centerpiece of a holiday or special occasion meals, such as Easter Sunday and Christmas Day. It can be reheated or prepared in various ways, including baking it slowly to preserve moisture, grilling it until crispy on the outside, cooking whole at low temperatures, or microwaving it for a quick meal.

But since it’s called pre-cooked ham, why would you need to cook it again? That’s a common question people ask all the time. So let’s discuss it.

Ham is cooked “pre-cooked” if it has been smoked, cured, or baked. You can tell because the package will say what kind of ham it is.
