How to cook it
- 1
Prepare. 500 g, straight from frozen. No oil; sweet potato never gets as crisp as regular fries — that is normal.
- 2
Cook. Cook at 180 °C for 22–24 min, shaking or turning as noted so the hot air reaches every side.
- 3
Check doneness. Judge by colour and crispness — pull it as soon as it looks right; the basket keeps cooking food for another minute.

FAQs
How long does frozen sweet potato fries take in an air fryer?+
22–24 min at 180 °C for 500 g, straight from frozen. Smaller loads finish at the low end; a fuller basket needs the top of the range.
Do I need to preheat?+
The chart behind this page (Ninja Dual Zone) needs no preheat. If your model recommends preheating, give it 2–3 minutes and keep the cooking time unchanged.
How is this different from the oven?+
The air fryer is a small convection oven: the same result in roughly half the time, because the chamber is tiny and the fan is close to the food.
How do I know it is done?+
By eye: even browning and the crispness you want. Err on the early side — you can always give it two more minutes.
