Make Ahead

One way to get ahead of the prep is to bake the potatoes and allow them to cool beforehand. Once cooled, scoop the insides into an airtight container and store them in the fridge for up to a week. This will take hours off your prep time.

As for the potato skins, store those in an airtight container with parchment between them to keep them from sticking to one another.
