Pierce each potato multiple times with a fork before cooking to allow steam to escape evenly, preventing bursting and ensuring a perfectly fluffy interior.

Wash potatoes thoroughly and pat completely dry with paper towels before spraying with nonstick spray to maximize skin crispness and prevent moisture buildup.

Apply sea salt directly to the damp potato skin after patting dry, as it adheres better and creates an even, flavorful seasoned crust throughout cooking.

Select potatoes of similar size to ensure they cook at the same rate, preventing some from being undercooked while others become overcooked.

Remove potatoes from the air fryer and let rest for 2-3 minutes, then cut open and fluff the insides with a fork to release steam and achieve maximum fluffiness.
