Preheat your air fryer to 400°F (200°C).
Wash and dry the zucchinis thoroughly.
Cut zucchinis into even rounds, about ¼ inch thick.
In a mixing bowl, combine olive oil, garlic powder, onion powder, salt, black pepper, and Italian seasoning.
Add zucchini rounds to the bowl and toss until evenly coated.
Place the zucchini in a single layer in the air fryer basket.
Cook for 10 minutes, shaking the basket halfway through.
Check for desired crispiness; cook for an additional 2-5 minutes if needed.
Remove from the air fryer and transfer to a serving dish.
Garnish with fresh parsley before serving.
