Position a rack in the center of the oven and preheat the oven to 400 (F).
Tightly wrap each sweet potato in a layer of aluminum foil and place on a parchment-lined half sheet pan.
Bake for 60 minutes, or until the sweet potatoes can be pieced easily with a fork. Turn off the oven and leave the sweet potatoes inside to cool with the oven.
Once at room temperature, place each sweet potato (still wrapped in the foil!) in an airtight container. Refrigerate until needed for the sweet potato filling (recipe below)—the sweet potatoes will keep in the refrigerator for up to 1 week.
