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...

“Other creatures receive food simply as fodder. But we take the raw materials of the earth and work with them—touch them, manipulate them, taste them, glory in their heady smells and colors, and then, through a bit of alchemy, transform them into delicious creations.”
― Judith Jones, The Tenth Muse: My Life in Food
