Preheat the air fryer to 400°F (200°C) for 3–5 minutes. A hot basket jump-starts browning and helps prevent sticking.
Wash and cut the potatoes evenly. Aim for 3/4-inch cubes or 1/2-inch thick wedges. Uniform size means even cooking and consistent texture.
Optional soak for extra crispness: If you have time, soak cut potatoes in cold water for 10–15 minutes to remove excess starch. Drain and pat very dry with a clean towel.
Season in a bowl: Toss potatoes with oil, salt, pepper, garlic powder, and any optional spices.
Coat thoroughly so every piece gets a little love.
Load the basket: Spread potatoes in a single layer. A small overlap is fine, but avoid piling. Work in batches if needed.
Air fry for 10 minutes. Don’t stir yet—this initial stretch sets the crust.
Shake or toss. After 10 minutes, shake the basket or use tongs to turn the potatoes for even browning.
Finish cooking for 8–12 more minutes. Total time is usually 18–22 minutes, depending on your air fryer and cut size.
Cook until the edges are deeply golden and the centers are tender when pierced.
Taste and adjust. Sprinkle with a pinch of salt while hot. Add herbs and a squeeze of lemon or splash of vinegar if you like brightness.
Serve immediately. Crispness is best right out of the fryer. Pair with eggs, grilled chicken, salmon, or a fresh salad.
