To prevent a spiral cut ham from drying out, cook it at 325°F covered with foil, and baste during the final minutes of cooking. Let it rest before serving.
To cook a spiral cut ham without drying it out, you should follow these steps: Preheat your oven to 325°F (163°C). Place the ham cut-side down in a roasting pan and cover it tightly with foil to keep in moisture. Bake the ham at the preheated temperature, usually 10 minutes per pound or until it reaches an internal temperature of 140°F (60°C). During the last 20-30 minutes of cooking, you can remove the foil and baste the ham with its juices or a glaze to add flavor and moisture. Let the ham rest for a few minutes before serving to allow juices to redistribute evenly.
