Pat the corn completely dry with paper towels before oiling—this removes surface moisture that prevents even browning and ensures a golden, caramelized exterior in the air fryer.

Apply just a light coating of canola oil (use a spray bottle for even distribution) to avoid greasy results while still achieving that perfect golden char and tender kernels.

Sprinkle coarse sea salt immediately after air-frying while the corn is still hot—this allows the salt to adhere better and creates a more pronounced, premium flavor compared to salting beforehand.

Place corn in a single layer with space between each ear to allow hot air to circulate completely—avoid stacking or crowding, which creates uneven cooking and steaming rather than air-frying.

Mix softened butter with fresh herbs like cilantro, lime zest, or chili powder before serving—this quick technique transforms basic buttered corn into an elevated side dish with restaurant-quality appeal.
