Preheat your air fryer to 400°F for three minutes while you prepare the corn. Rinse each ear under cool water and pat completely dry with paper towels—moisture prevents the seasoning from sticking properly.
In a small bowl, whisk together melted butter, garlic powder, paprika, salt, black pepper, and cayenne until smooth and fragrant. This aromatic butter is the secret to making this crispy summer side absolutely irresistible to kids and adults alike.
Brush the seasoned butter mixture generously over each ear, rotating to coat all sides evenly. Don't skip this step—the coating creates that golden, crispy exterior everyone loves about quick cookout favorites.
Arrange the 6 coated ears in the air fryer basket in a single layer, standing them upright or laying them flat depending on your basket size. Work in batches if needed to avoid crowding; air circulation is essential for even cooking and that perfect crispy texture.
Air fry at 400°F for 12 minutes, shaking the basket halfway through at the 6-minute mark for even browning. The kernels should look golden and slightly charred at the tips when done.
Transfer the air fryer corn on the cob family recipe to a serving platter and immediately sprinkle fresh parsley and grated parmesan while still steaming hot. This ensures the cheese melts slightly and the herbs release their aromatic oils across every kernel.
Arrange lime wedges alongside for squeezing over the top—the bright citrus cuts through the richness of butter and adds a fresh finish. Serve immediately while piping hot for maximum enjoyment.
