Turn on the air fryer and select the “Air Crisp” function. Set the temperature to 400°F and adjust the timer to 18 minutes. Press “Start” to pre-heat the air fryer.

While the unit pre-heats, get a large bowl to combine the potatoes, olive oil, dried rosemary, and garlic powder. Add salt and black pepper, to taste. Toss to combine.

When the air fryer beeps and flashes “Add Food,” pour the seasoned potatoes into the basket and spread into an even layer without overcrowding. Close the lid to start air frying.

After 9 minutes, lift the lid and carefully turn the potatoes with a plastic spatula so they brown evenly. Make sure they are still in an even, single layer. Close the lid and continue air frying. Do this until the cook time is complete and you achieve your personal preference of the potatoes' golden perfection.

Transfer the golden brown potatoes to a serving bowl or platter. Place freshly grated Parmesan cheese on top of the potatoes, if desired. Garnish with sprigs of leftover rosemary or parsley and serve immediately. Enjoy!
