01 - Insert a long wooden or metal skewer lengthwise through the center of each scrubbed potato.
02 - Holding the skewer, use a sharp knife to cut in a spiral motion, rotating and slicing from one end to the other. Stretch the potato along the skewer to create evenly spaced spirals.
03 - Combine olive oil, garlic powder, smoked paprika, salt, and black pepper in a small bowl.
04 - Brush or rub the seasoning mixture evenly over each spiraled potato, ensuring coverage between layers.
05 - Set the air fryer to 375°F (190°C) and preheat for 3 minutes.
06 - Place the seasoned, skewered potatoes in the air fryer basket, ensuring they are not touching.
07 - Air-fry the potatoes for 20 to 25 minutes, turning halfway through, until they are golden and crisp.
08 - If desired, sprinkle with Parmesan cheese, fresh parsley, and chili flakes before serving.
