Cut the zucchini. Use a sharp knife to cut your zucchini in half long ways, and then each half in half again. Cut them in half widthwise to make 8 sticks total out of each zucchini that are about 4 inches long and ½ inch thick.
Season your flour. In a large bowl, combine the flour, salt, garlic powder, paprika, onion powder, and pepper. Toss the zucchini sticks in the flour mixture until well coated.
Prepare the breadcrumbs. In a separate large bowl, combine breadcrumbs and parmesan cheese.
Bread the zucchini. One by one, coat the floured zucchini sticks in the egg and then roll it into the breadcrumb mixture. Set them aside to a platter or wire rack so that they are all ready to cook.
Prepare your air fryer. Spray your air fryer with a cooking spray or use a non-stick liner.
Cook. In batches, cook the zucchini fries in a single layer in your air fryer on 350°F for 10 mins.
Make the sauce. In a small bowl, mix the mayonnaise, dill and garlic powder and refrigerate until ready to serve.
Serve. Serve your zucchini fries warm with dipping sauce on the side.
