Question: how long does it take to heat up a fully cooked ham in the oven?
Answer: If you're starting with a fully cooked city ham, bake it in a 350 degree F oven for about 10 minutes per pound. If your ham is only partially cooked, bake it for 20 minutes per pound. To help keep your ham moist and juicy, place the ham cut-side down in a baking pan and tent it with foil.
