Wash and thinly slice the zucchini into rounds. Pat them dry thoroughly with paper towels to remove excess moisture.
In a shallow dish, whisk the eggs. In another shallow dish, combine the flour, panko breadcrumbs, garlic powder, onion powder, paprika, salt, and pepper.
Dip each zucchini slice first into the beaten eggs, then into the breadcrumb mixture, ensuring it's well coated.
Preheat your air fryer to 400°F (200°C). Lightly brush the air fryer basket with olive oil or use parchment paper.
Arrange the coated zucchini slices in a single layer in the air fryer basket, making sure not to overcrowd. You may need to cook in batches.
Air fry for 10-12 minutes, flipping halfway through, until golden brown and crispy. Cook time may vary depending on your air fryer.
Serve hot with your favorite dipping sauce.
Notes
For extra crispiness, ensure the zucchini slices are very dry before coating. You can adjust seasonings to your preference.
