Yes, you can freeze the pre-baked fries/wedges. -First, wash and then slice the fries. Then, transfer them to a saucepan with boiling water and blanch for 3 minutes. -Immediately transfer them to an ice bath to halt the cooking process. Leave them to soak for 15-20 minutes. -Drain and rinse them well, then transfer them to a clean kitchen towel and thoroughly dry. -Then, spread them across a tray, not touching, and flash freeze until solid. -Finally, transfer to a large Ziplock/Stasher bag or freezer-safe container and store for up to 6 months. Cook them from frozen, adding a few extra minutes to the cooking time. You can season them before or directly after cooking.
