Lumpia can be frozen either before or after frying. If you plan on freezing unfried lumpia, make sure to first place them on a platter or large tray in the freezer until they are almost frozen. You can then store them in a large freezer Ziploc bag. This will ensure that the lumpia does not stick together. Frying Frozen Lumpia You do not need to defrost frozen lumpia prior to frying them. Just follow the same frying instructions listed in the recipe, with the exception of adding a few additional minutes to the frying time. Reheating Cooked and Frozen Lumpia If the lumpia are frozen after they are fried, you can microwave them, a few at a time, for approximately one to two minutes. The exact time will depend on the wattage of your microwave. For a crispier texture, bake the fried and frozen lumpia for approximately ten minutes in a 350-degree F oven. Using a toaster oven is an even better option and requires less time. Lumpia can also be reheated in an air fryer.
