First, preheat your air fryer to 390°F (200°C) for about 3 to 5 minutes. Starting with a hot air fryer helps the corn cook more evenly and gives the kernels a perfect, juicy bite.
Next, place each ear of corn on a sheet of aluminum foil large enough to wrap it completely.
Then, spread 1 tablespoon of butter over each ear of corn and sprinkle with a pinch of salt. Wrap the foil tightly around the corn to seal in all that buttery goodness and moisture.
Place the wrapped ears into the air fryer basket in a single layer. Air circulation is key, so avoid stacking them. Cook for 10 - 13 minutes.
After 10 minutes, carefully remove the foil using tongs (they’ll be hot!). Return the unwrapped corn to the basket.
Finally, air fry the corn for another 3 minutes, uncovered. This step gives the kernels a lovely golden finish and a hint of crispness on the edges.
Serve hot with an extra pat of butter, if you'd like, and enjoy every sweet, buttery bite!
