Wash and peel the sweet potatoes. Cut them into even 1/4-inch thick sticks.
Place the cut potatoes in a bowl. Drizzle with olive oil and sprinkle salt, garlic powder, onion powder, paprika, and a pinch of black pepper. Toss well to coat evenly.
Preheat your air fryer to 380°F. Arrange the fries in a single layer in the air fryer basket without overcrowding.
Cook for approximately 11-14 minutes, shaking the basket halfway through, until crispy and golden. Cooking time may vary depending on your specific air fryer model.
Garnish with parsley if desired and serve immediately with your favorite dipping sauce.
