Question: how long do you heat a precooked spiral ham?
Answer: Bake in a preheated 325°F oven for 10-14 minutes per pound, or until a meat thermometer registers 140°F. To glaze this type of ham, turn the oven to 400°F, brush the ham with the glaze, and bake for 10-15 minutes until the glaze is browned and bubbling.
