The air fryer is the quickest way to reheat this iconic fast-food snack while preserving its integrity. In a matter of minutes, you'll have hot and crispy nuggets.
This is enough time to heat them through without scorching them. Add the Mcnuggets in a single layer, even if it means heating only a portion of them at a time.
There has to be sufficient room between the nuggets for the air to heat them. You should also check them occasionally to ensure they don't get too brown or burn.
