Yes! To freeze plantains, peel and cut them into slices or chunks. Place them on a single layer on a baking sheet and freeze for 2-3 hours or until solid. Once frozen, transfer them to a freezer-safe bag or container and store them in the freezer. When you're ready to fry, there's no need to thaw—just put them straight into the hot oil.  Frozen plantains can be stored in the freezer for up to 3 months.
