There are a few different ways to store leftover Easter ham. The most important thing is to make sure that it's properly sealed in an airtight container. Store leftover holiday ham in the refrigerator for 3-4 days. If you're not going to eat your leftover ham within four days, you can freeze it. You can freeze the ham by wrapping it tightly in plastic wrap or aluminum foil. You can also vacuum seal it using a food sealer. If you're going to freeze the ham, make sure to thaw it completely before cooking. Ham can be stored in the freezer for up to three months. Store the ham bone in a separator container.
