Start by draining the dill pickle slices and patting them dry with paper towels to remove excess moisture.
In a shallow dish, combine the flour, garlic powder, onion powder, paprika, and cayenne pepper. Mix well.
In a separate mixing bowl, crack the eggs and beat them until well combined.
Place the breadcrumbs in another shallow dish.
Preheat your air fryer to 380°F (190°C) for about 5 minutes.
Take each pickle slice, dip it into the flour mixture, ensuring it’s fully coated, then shake off any excess.
Next, dip the floured pickle slice into the beaten eggs, allowing any excess egg to drip off.
Finally, coat the pickle slice in breadcrumbs, pressing gently to adhere. Place the coated pickles on a plate.
Once all pickle slices are coated, spray the air fryer basket lightly with cooking spray.
Arrange the coated pickles in a single layer in the basket, making sure they do not overlap.
Spray the tops of the pickles lightly with cooking spray to promote browning.
Cook in the air fryer for 8-10 minutes, flipping halfway through, until golden brown and crispy.
Remove from the air fryer and place on a paper towel to absorb any excess oil.
Serve warm with ranch dressing for dipping, if desired.
