Preheat the air fryer to 200°C (400°F).
Place the dry, uncooked gnocchi in a large mixing bowl.
Add olive oil, garlic powder, oregano, salt, and pepper to the bowl.
Toss ingredients vigorously until the gnocchi surface area is completely and evenly coated.
Distribute the gnocchi into the air fryer basket in a single layer to ensure maximum airflow.
Air fry for 15 minutes, pausing to shake the basket every 5 minutes for even thermal distribution.
Transfer the gnocchi to a serving vessel and immediately toss with grated Parmesan cheese while the surface oil is still active to ensure adhesion.
