Step 1: Begin by peeling your apples. This helps create that smooth 'fry' texture. Next, carefully core the apples and slice them into ¼-inch thick strips, mimicking the shape of classic French fries. Opting for firm apples like Honeycrisp or Granny Smith is key here, as they maintain their structure and crispness during cooking.
Step 2: Prepare three separate bowls for the coating process. In the first bowl, place the all-purpose flour. In the second, whisk the two eggs until well beaten. For the third bowl, combine the graham cracker crumbs with the cinnamon and sugar. If you're looking for an alternative crunch, crushed cornflakes work wonderfully here too!
Step 3: One by one, dredge each apple slice in the flour, shaking off any excess. Then, dip it into the beaten egg, ensuring full coverage. Finally, transfer the egg-coated apple slice into the graham cracker mixture, pressing gently to make sure the crumbs adhere well. Place the coated fries on a plate or tray as you work through all your apple slices.
Step 4: For optimal crispiness and even cooking, preheat your air fryer to 380°F (195°C) for about 3 minutes. This step is crucial for achieving that desired golden-brown exterior.
Step 5: Lightly spray the air fryer basket with cooking spray to prevent sticking. Carefully arrange the coated apple fries in a single layer, ensuring there's space between each piece for proper air circulation. If you have a large batch, cook them in multiple rounds to avoid overcrowding.
Step 6: Cook the apple fries at 380°F (195°C) for 6-8 minutes, flipping them halfway through. Keep a close eye on them during the final minutes; they should be beautifully golden brown and crispy. Once done, remove them and serve immediately.
