Preheat the air fryer to 400°F (200°C) for about 5 minutes.
In a large bowl, toss the potato wedges with olive oil, garlic powder, onion powder, smoked paprika, dried thyme, salt, and black pepper. Ensure the wedges are evenly coated.
Place the seasoned potato wedges in the air fryer basket in a single layer, ensuring they are not overcrowded.
Air fry the potato wedges for 18-20 minutes, shaking the basket or flipping the wedges halfway through the cooking time for even crispiness.
Check the potato wedges for doneness; they should be golden and crispy on the outside.
Remove the potato wedges from the air fryer and let them cool for a few minutes.
Serve the Homemade Grilled Potatoes hot, garnished with fresh chopped parsley if desired.
