Shuck the Corn. Remove the husks and silk from the corn.
Season the Corn. Drizzle each ear of corn with olive oil, then sprinkle generously with Cajun seasoning, salt, and black pepper. Rub the seasoning into the corn to ensure it's evenly coated.
Preheat the Air Fryer. Set your air fryer to 400°F.
Arrange the Corn. Place the seasoned corn in a single layer in the air fryer basket. Do not overcrowd to ensure even cooking.
Cook. Air fry the corn for 10-12 minutes, turning halfway through, until the corn is golden brown and slightly charred.
Optional Garnishes. While the corn is still hot, you can brush it with butter, sprinkle with fresh parsley, and serve with lemon wedges.
Enjoy. Serve your Cajun corn on the cob hot. It pairs perfectly with grilled meats, salads, or as a standalone snack.
