Preheat your air fryer to 400°F (200°C) for a few minutes.
Place the frozen waffle fries in the air fryer basket in a single layer. Do not overcrowd the basket to ensure even cooking.
Cook the waffle fries in the air fryer for 10-15 minutes, shaking the basket halfway through the cooking time to ensure even cooking.
Check the waffle fries for doneness. If they are not crispy enough, continue cooking for an additional 2-3 minutes.
Once the waffle fries are crispy and golden brown, remove them from the air fryer and serve immediately.
