01 - Pat zucchini slices dry with paper towels to remove excess moisture, which ensures maximum crispiness during cooking.
02 - In a shallow bowl, combine panko breadcrumbs, grated Parmesan cheese, garlic powder, paprika, salt, and black pepper. Stir until evenly distributed.
03 - In a separate shallow bowl, beat the eggs until well combined.
04 - Dip each zucchini slice into the beaten egg, then coat thoroughly with the breadcrumb mixture. Arrange in a single layer in the air fryer basket without overcrowding, working in batches if necessary.
05 - Lightly spray the coated zucchini slices with olive oil spray to enhance browning and crispiness.
06 - Set air fryer to 400°F and cook for 8 to 10 minutes, flipping halfway through cooking, until golden brown and crispy. Work in batches if needed to maintain single-layer arrangement.
07 - In a mixing bowl, combine sour cream, mayonnaise, dill, chives, parsley, onion powder, garlic powder, salt, and black pepper. Whisk until smooth and creamy. Adjust seasoning and lemon juice to taste.
08 - Transfer hot zucchini chips to a serving platter and accompany with ranch dip on the side. Serve immediately for optimal texture.
