Start by washing your fingerling potatoes thoroughly to remove any dirt and debris. Slice each potato in half lengthwise.
In a mixing bowl, combine the halved fingerling potatoes with olive oil, garlic powder, dried parsley, salt, and black pepper. Toss well until evenly coated.
Preheat your air fryer to 400°F (200°C) for about 5 minutes to ensure even cooking.
Place the seasoned fingerling potatoes in a single layer in the air fryer basket. Cook for 15-20 minutes, shaking the basket halfway through.
Check for doneness; the potatoes should be golden brown and crispy. If needed, continue cooking in 2-3 minute increments.
Carefully remove the fingerling potatoes from the air fryer and serve hot. Garnish with herbs or parmesan cheese if desired.
