Start by rinsing the apples thoroughly under cool water to remove any residue. Next, slice them into fry-shaped sticks, ensuring to core the apples so that no seeds remain. Aim for uniform thickness (around 1/4 inch) to ensure even cooking.

In a mixing bowl, combine cornstarch, sugar, cinnamon, and a pinch of salt. Mix well until all ingredients are thoroughly blended.

Add the sliced apple fries to the bowl with the cornstarch mixture. Gently toss the strips, ensuring they are all evenly coated.

Preheat your air fryer to 180°C (350°F). Lightly spray the air fryer basket with oil.

Carefully arrange the apple fries in a single layer in the preheated air fryer basket. Air fry for 8 to 10 minutes, shaking the basket halfway through.

Check the apple fries for doneness. They should be golden brown and crispy on the outside.

Once cooked, carefully remove them from the air fryer using tongs. Serve immediately with caramel sauce or yogurt for dipping.
