How long do you cook a fullly cooked 3 lb ham in a crock pot?
If the ham is fully cooked, there is no need to cook it any
further. You could serve it just as it is...even cold. You may wish
to heat the ham before serving it, but that shouldn't take very
long in the oven, maybe an hour at 350 degrees. The crock pot could
take a lot longer and would over-cook the ham.
