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 each potato in a spiral motion, rotating and slicing evenly from end to end. Gently stretch the potato along the skewer to space the spirals.
03 - In a small bowl, combine olive oil, garlic powder, smoked paprika, salt, and black pepper.
04 - Brush or rub the seasoning mixture thoroughly over each spiraled potato, ensuring it penetrates between the slices.
05 - Preheat the air fryer to 375°F for 3 minutes.
06 - Place the skewered potatoes in the air fryer basket, spaced apart to prevent touching.
07 - Air-fry at 375°F for 20 to 25 minutes, turning skewers halfway through the cycle, until golden brown and crisp.
08 - Before serving, optionally sprinkle with grated Parmesan, chopped parsley, and chili flakes.
