For even crispier skin, you can lightly mist the potatoes with cooking spray during the last 5 minutes of air frying. Different potato varieties like Yukon Gold will yield a slightly different texture, but Russets are ideal for that classic fluffy interior. Experiment with your favorite spices – a pinch of smoked paprika or onion powder can elevate the flavor profile. To ensure doneness, insert a thin skewer or fork into the thickest part; it should slide in easily.
