FAQs

How long does green beans take in an air fryer?+

7–8 min at 200 °C for 400 g, trimmed. 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 runs the same job in roughly half the time of an oven thanks to fast air circulation in a small chamber. The oven version takes 15-18 min — see the oven guide for this product.

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.
