Preheat your air fryer to 400°F (200°C).
In a large bowl, combine ground beef, breadcrumbs, Parmesan cheese, egg, garlic, salt, black pepper, oregano, and basil. Mix until well combined but do not overmix.
Shape the mixture into 1.5-inch meatballs.
Arrange the meatballs in a single layer in the air fryer basket, ensuring they do not touch each other. You may need to cook in batches depending on the size of your air fryer.
Cook for 10 minutes, or until the meatballs are browned and cooked through, flipping halfway through the cooking time.
Serve hot with your favorite dipping sauce or over pasta.
