Drain pickles completely and pat dry with paper towels.
Press pickles between fresh paper towels to remove any remaining moisture.
Beat the egg in the first shallow bowl until uniform.
Pour panko breadcrumbs into a second shallow bowl.
Preheat the air fryer to 380°F for 3 minutes.
Dip each pickle coin in the beaten egg and shake off excess.
Press both sides of each pickle into the panko until fully coated.
Arrange coated pickles in a single layer in the air fryer basket; do not overlap.
Lightly drizzle or spray olive oil over the tops of the pickles.
Air fry for 6 minutes without opening the basket.
Flip each pickle with tongs.
Cook an additional 6 minutes, or until golden brown and crispy.
Serve immediately with remoulade sauce for dipping.
