Yes, you can! Freeze your air fried eggplants BEFORE you put on the garlic sauce. To freeze, place the roasted air fried eggplant slices on a lined baking sheet in the freezer for about 3 hours. Once frozen solid, you can then place in the freezer baggie in a single or sealed container for up to 3 months. Then, when you are ready to eat, you can place the frozen eggplant slices directly in the air fryer at 350 degrees F (176 degrees C) for 5 to 10 minutes or until toasty hot.
