Yes! If you would like to prepare these ahead of time so you have them on hand when needed, simply place the prepared, uncooked mozzarella sticks in a freezer safe container and keep stored in the freezer for up to 4 months. Simply pop in the air fryer as instructed when ready to enjoy. If you've already cooked these mozzarella sticks, you can store them in the fridge in air-tight containers for up to 5 days and reheat in an air fryer or convention oven at 350F until warmed throughout.
