Cut each zucchini in half, then slice into spears.
In a medium bowl, toss the zucchini spears in lemon juice.
In a shallow bowl, whisk eggs together to create an egg wash.
In another shallow bowl, prepare the breading by mixing panko breadcrumbs, parmesan, garlic powder, onion powder, paprika, and salt.
Coat each zucchini spear by dipping it in the egg wash, then rolling it in the breadcrumb mixture, pressing gently to coat evenly.
Arrange the zucchini fries in a single layer in the air fryer basket and spray the tops lightly with cooking spray.
Air fry at 400°F for 10-12 minutes, flipping halfway through and spraying the other side with cooking spray. The zucchini fries should be golden brown and crispy.
For the Greek yogurt dill dip, mix all the dip ingredients in a small bowl and whisk until combined.
Serve the zucchini fries as is or with the Greek yogurt dill dip. Enjoy!
