About 20-30 minutes per pound... Boil it with onions for a nice flavor.
You should cook a 10 lb ham at 350 degrees for about 2.5 to 3 hours.
A 20 lb ham should be cooked for about 4 to 5 hours at 325F until it reaches an internal temperature of 140F.
Usual you cook a ham 20 minutes per pound at 325
20 min per lb.
About 5 hours for a 10-lb ham.
About 1.5 to 2 hrs, depending on the type of ham. Meat thermometer inserted into the ham should read 170F or 77 C.
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.
It is pre-cooked....so you don't have to cook it at all. You may eat it cold. If you prefer to eat it warm or hot you may warm in microwave or oven. The best way to heat a ham in the oven is to place it in a glass dish and cover the top of it with tinfoil...then bake at 350 degrees. The amount of time to bake is based on how warm or hot you want the ham. Cook it to your desired temp and serve.

do not cook it is precooked. heat at 350 for 20 min/lb
5 hours 24 minutes
I'd say 8 to 12 hours to thaw and it depends on how you want to prepare it before you cook it. A lot of sauces/ spices= longer cooking time, lower setting
