Begin by thoroughly rinsing and drying your apples. Slice them into ¼-inch rings, carefully removing the cores with a small cutter. Pat the rings dry to ensure optimal coating adherence.

Set up three shallow bowls for the coating process. In one bowl, whisk the beaten egg and milk together. In another bowl, mix a pinch of salt into the flour. In the third bowl, combine breadcrumbs and cinnamon.

Dip each apple ring into the flour, shaking off any excess. Immerse the rings in the egg wash, then press each into the breadcrumb-cinnamon mixture.

Preheat your air fryer to 375°F (190°C). Arrange the coated apple rings in a single layer and lightly spray with cooking spray. Cook for 6-8 minutes, flipping halfway through.

After air frying, allow the rings to cool for about a minute. Plate your Air Fryer Cinnamon Apple Rings and consider adding powdered sugar or honey.
