Believe it or not, you can freeze a ham bone the same way as freezing the meat. Simply wrap it and place it in a bag, just like storing cooked ham. Make sure you cover all exposed parts and keep away from extremely cold areas. While it’s less common with thick bones, it’s possible for bones to crack or break in the freezer.
When it’s time to use the bone, allow it to thaw and slowly rise in temperature by placing it in the refrigerator the night before you need it.
