Preheat your air fryer to 375°F (190°C).

Slice apples into ¼-inch rings and remove the cores with a small round cutter.

In one bowl, combine flour and salt. In another, whisk together egg and milk. In a third bowl, mix breadcrumbs, sugar, and cinnamon.

Dip each apple ring into the flour, then the egg mixture, and finally coat with the cinnamon breadcrumb mix.

Lightly spray the air fryer basket with cooking spray and arrange the rings in a single layer (work in batches if needed).

Air fry for 6–8 minutes, flipping halfway through, until golden brown and crispy.

Sprinkle with powdered sugar or drizzle with honey before serving warm.
