Do you always have leftover mashed potatoes after Thanksgiving? Here’s a great way to store them.

Using a large ice-cream scoop or a measuring cup, place 1-cup portions of mashed potatoes on a baking sheet lined with parchment paper, then transfer the baking sheet to the freezer. Once the potatoes are frozen, transfer them to a large zipper-lock bag and put them back in the freezer.

To reheat the potatoes, place a portion in a microwave-safe bowl, cover with plastic wrap, and microwave at 50 percent power for about 5 minutes, stirring occasionally, until they’re heated through.
