Oven roasted potatoes need 40-45 minutes at high heat plus parboiling time if you want them truly fluffy inside. Air fryer potatoes skip the parboiling, take 18-22 minutes, and produce a better crisp-to-fluff ratio because the circulating air hits all sides at once. It is a meaningfully better result, not just a faster one.
Floury or all-purpose varieties produce the fluffiest inside: Maris Piper, King Edward, Desiree, Yukon Gold. Waxy varieties (Charlotte, Jersey Royal) stay firm throughout and do not get the fluffy interior - they are good for salads but not roasting.
Cut size affects cooking time and texture. 3cm chunks give you the best fluffy-to-crispy ratio. Smaller than 2cm and you get mostly crust. Larger than 4cm and the inside is dense by the time the outside is crispy.
Peel and cut potatoes into 3cm chunks. Pat completely dry - this is essential. Wet potato surfaces steam in the air fryer and the skin stays soft. Toss with 1-2 tbsp oil, salt, and any seasoning. Do not over-oil - more than 2 tbsp for 600g of potato and they turn greasy rather than crispy.
Preheat the air fryer to 200C / 400F for 3 minutes. Add potatoes in a single layer - slight overlap is fine but do not stack them. Cook for 18-22 minutes, shaking the basket twice (at 8 minutes and 15 minutes). They are done when golden brown and a fork goes through the centre easily.

Leftover air fryer potatoes reheat better than oven-roasted ones. 4 minutes at 180C brings them back close to fresh - the crust re-crisps rather than going rubbery. This makes them worth cooking in large batches: roast 1kg on Sunday, reheat portions across the week as needed.
Potatoes pair with everything in this cluster. Cook them first (they take longest), then run chicken thighs, pork chops, or fish fillets in the same basket while the potatoes rest.
