Place the pickles on paper towels and make sure to pat them completely dry.
In a bowl, wisk egg whites.
In another bowl, mix the flour, salt, garlic powder, onion powder, smoked paprika, black pepper and cayenne pepper.
Dip the pickles into the egg whites, followed by the flour mixture, shaking off any excess flour.
Preheat your air fryer to 400F. Lay the pickles in an even layer in the air fryer making sure they are not overlapping. Spray the pickles liberally with cooking spray and cook for 15 minutes, making sure to flip halfway through cooking.
Repeat this process until all the pickles have been cooked.
Use just egg whites rather than the whole egg for dredging. This creates a much lighter and crisper texture.
Place the pickles in a single layer in the basket. If they are overlapping they won't get crispy all over, it's much better to cook in smaller batches than one big one.
Remember to flip the pickles halfway through cooking, and be sure to pre heat your air fryer.
