Prep the apples by peeling and cutting them into fry-shaped sticks, roughly 1/4 inch thick. Pat dry with a paper towel.

Set up a breading station with three bowls: one with flour, one with whisked egg and milk, and one with panko mixed with cinnamon and sugar.

Dredge each apple fry in flour, dip in egg mixture, and coat in panko, pressing gently to ensure even coating.

Spray the air fryer basket with nonstick cooking spray and place the apple fries in a single layer. Air fry at 375°F for about 8–10 minutes, shaking halfway through.

Check for a golden brown color and crispness after 8 minutes. Adjust cooking time if needed.

Remove fries from the air fryer, toss in extra cinnamon-sugar if desired, and serve warm with dipping options.
