Preheat the air fryer to 400°F (200°C) for 5 minutes.
Place the peeled and cut sweet potato fries in a large bowl.
Add the olive oil, garlic powder, smoked paprika, salt, and black pepper to the bowl with the sweet potatoes.
Toss the fries thoroughly to ensure they are evenly coated with the oil and seasonings.
Arrange the fries in a single layer in the air fryer basket. Avoid overcrowding to ensure even cooking; cook in batches if necessary.
Air fry the sweet potato fries at 400°F (200°C) for 10 minutes.
After 10 minutes, shake the basket or use tongs to flip the fries for even crisping.
Continue air frying for an additional 8-10 minutes or until the fries are golden brown and crispy on the edges.
Remove the fries from the air fryer and transfer them to a serving bowl.
Sprinkle the chopped fresh parsley over the fries and toss gently to combine.
Serve immediately while hot and crispy.
