01 - Slice the peeled sweet potatoes into uniform 1/4-inch thick batons. Consistent sizing ensures even cooking and uniform crispiness.
02 - Submerge the cut fries in a large bowl filled with cold water. Let soak for 30 minutes to remove surface starch, then drain completely and pat dry with paper towels. Moisture removal is critical for achieving crispiness.
03 - Transfer the dried fries to a clean bowl. Drizzle with olive oil and toss to coat evenly. Sprinkle the cornstarch, smoked paprika, garlic powder, salt, and pepper over the fries. Toss vigorously until each fry is thoroughly coated with the seasoning mixture.
04 - Preheat the air fryer to 400°F for 3 minutes before cooking. A hot cooking surface promotes immediate crisping.
05 - Place the seasoned fries in the air fryer basket in a single layer. Do not overcrowding—cook in multiple batches if necessary. Proper air circulation is essential for crispy results.
06 - Cook at 400°F for 15-18 minutes, shaking the basket vigorously at the halfway mark to redistribute the fries. Continue cooking until golden brown and crispy throughout.
07 - Transfer the fries to a serving plate while hot. Season with additional salt if desired. For optimal texture and flavor, serve promptly with your preferred dipping sauce.
