Ah, the classic centerpiece. Spirals are always pre-cooked. They are already sliced, so they heat up fast and dry out even faster.
Cover that spiral ham tightly with foil. Bake it at 275°F for about 10 minutes per pound until it hits 140°F. That low heat will save the moisture.
I once brushed mine with a brown sugar glaze. It was sticky, sweet, and the best thing I’d accidentally made. Just don’t skip the foil, or you will have ham jerky.
