Yes! There are a couple of ways to freeze them. You can freeze already-baked chicken empanadas, or you can freeze the filled and un-baked empanadas. Either way, lay the empanadas flat on a lined baking tray and freeze until solid. Then, transfer them to an airtight container or freezer bag. Freezing them flat first ensures that they won’t stick together or get squashed. To bake the frozen uncooked empanadas, add a few extra minutes to the baking time and bake until golden and heated through. To reheat already-cooked empanadas, place them into the oven at 180 C for around 8 minutes, or until the pastry is crisp and the mixture is steaming and thoroughly heated through.
