Preheat air fryer to 400°F (200°C).
In a medium bowl, combine Parmesan cheese and eggs.
Mix until fully combined.
Roll mixture into 10–12 balls.
Optional: Freeze balls for 30 minutes before air frying to help hold their shape even better.
Line the air fryer tray with air fryer-safe parchment paper.
Air fry for ~6 minutes or until golden and crispy on the outside.
Allow to cool slightly and serve with marinara sauce.
