Preheat your air fryer to 200°C (400°F).
In a large bowl, whisk together the melted butter, olive oil, pepper, salt and grated cheese. Add in the gnocchi, and toss until it's evenly coated.
Transfer the gnocchi to the air fryer basket in one layer, leaving space between to allow for good airflow. This will ensure the gnocchi get crispy.
Cook for 8-10 minutes, until the gnocchi are golden brown and crispy.
Serve warm with more grated cheese (optional).
