Preheat your air fryer to 400°F (200°C).
Remove the husks and silk from each ear of corn. If needed, cut the cobs in half so they fit comfortably inside the basket.
In a small bowl, combine the melted butter, parsley, and sea salt.
Place the corn in the air fryer basket in a single layer.
Brush all sides generously with the butter mixture.
Cook the Air Fryer Corn on the Cob for 12–14 minutes, turning halfway through if desired, until the kernels are tender and lightly browned.
Brush with any remaining butter mixture before serving.
