In a large bowl, toss the potatoes with the olive oil, garlic powder, Italian seasoning, salt, and several grinds of pepper.
Arrange in a single layer in the air fryer basket, leaving a little space between potatoes. Work in batches if necessary.
Air fry for 15 to 20 minutes, flipping halfway, or until the potatoes are tender and browned around the edges. Season to taste, garnish with parsley, and serve.
