Start by washing the zucchini thoroughly. Cut off both ends and slice the zucchini into thin rounds, about 1/8 inch thick.
Pat the zucchini slices dry with a kitchen towel or paper towels to remove excess moisture.
In a mixing bowl, combine the olive oil, garlic powder, onion powder, paprika, salt, and black pepper. Stir until well mixed.
Add the zucchini slices to the bowl and toss them gently in the oil and seasoning mixture until they are evenly coated.
Preheat the air fryer to 375°F (190°C) for about 3 minutes.
Once preheated, arrange the zucchini slices in a single layer in the air fryer basket.
Cook the zucchini chips in the air fryer for about 12-15 minutes, shaking the basket halfway through.
Once they are golden brown and crispy, remove the zucchini chips from the air fryer and let them cool slightly.
If desired, sprinkle with grated parmesan cheese while still warm.
Serve immediately and enjoy your crunchy zucchini chips as a healthy snack!
