Do you have a roaster oven? We often have cooked potatoes in a roaster oven at church, it takes longer as they are piled up...or you can bake some and move to a roaster oven to keep them warm...I think they need to be baked close to the serving time, refrigerated baked potatoes just taste different from fresh baked! JMHO...

Winter is the time for comfort, for good food and warmth, for the touch of a friendly hand and for a talk beside the fire: it is the time for home.”
