Ridge Creek is the Sam’s Club brand of spiral ham. This spiral ham is precooked, but must be warmed in order to kill any harmful bacteria that may reside in the ham from processing. According to the USDA Ham and Food safety guide, a ham is done cooking when it has a core temperature of 160 degrees Fahrenheit.
Preheat the oven to 350 degrees Fahrenheit.
Remove the ham from its packaging and place it into a 1 1/2 quart baking dish.
Add any desired cooking spices to the ham and cover in foil wrap to hold in moisture.
Bake for 30 minutes, or until a thermometer inserted into the center of the ham reads 160 degrees Fahrenheit.
