Preheat the Air Fryer to 380 degrees F.
Pat dry the fish with a kitchen towel and set it aside.
Prepare the breading station: In the first bowl, combine the all-purpose flour, paprika, garlic powder, salt, and pepper. Whisk the egg in the second bowl, whisk the egg, and in the third bowl. Set it aside.
Dredge the fish steps in the flour mixture first and then into the egg mixture and, finally, the panko mixture and gently press it until evenly coated. Repeat the same with the remaining fish strips.
Spray each side of the fish strips with cooking spray and place the fish in a single layer on an air fryer basket. Air fry them for 10 - 12 minutes, flip them halfway through, and cook until the fish turns golden and crispy.
Once done, transfer the fish to a serving platter, garnish with parsley, and serve it with french fries and your favorite dip on the sides.
