Prepare the Potatoes: Wash and scrub the russet potatoes to remove any dirt. Pat them dry with a paper towel. Cut the potatoes into bite-sized cubes or wedges.

Season the Potatoes: In a large mixing bowl, add the potato cubes or wedges. Drizzle the olive oil over the potatoes, ensuring they are well coated.

Add the Seasonings: Sprinkle the garlic powder, onion powder, paprika, dried oregano, dried thyme, salt, and black pepper over the potatoes. Toss the potatoes in the bowl to evenly distribute the seasonings.

Preheat the Air Fryer: Preheat your air fryer to 400°F (200°C) for a few minutes.

Air Fry the Potatoes: Place the seasoned potato cubes or wedges in the air fryer basket in a single layer, ensuring they are not overcrowded. Air fry the potatoes for about 15-20 minutes, shaking the basket or tossing the potatoes halfway through for even cooking. The potatoes should be golden brown and crispy on the outside and tender on the inside.

Add Parmesan Cheese: Once the potatoes are done, transfer them back to the mixing bowl. Sprinkle the grated Parmesan cheese over the hot potatoes and toss gently to coat them with the cheese.

Garnish and Serve: If desired, garnish the Air Fryer Parmesan Potatoes with chopped fresh parsley for a pop of color. Serve immediately as a delectable side dish or appetizer.
