Broad starting range: 180–200°C for around 12–30 minutes.

Use the package instructions first. The early end suits a small, loose portion; thicker fries or a fuller drawer usually need more time and more shaking.

Use the AF400 drawers well

  • One drawer: spread the fries as loosely as practical, then shake at least once during cooking.
  • Both drawers: treat each drawer as separate. MATCH is useful for equal loads; use SYNC only when different foods need to finish together.
  • Small frozen portions: Ninja identifies Max Crisp as a programme for smaller amounts of frozen food; check frequently because browning can accelerate.
  • Full drawers: do not expect a single unbroken layer of fries to brown evenly. Shake more often or cook in batches for a crisper result.

Check these signs before serving

Look for an even golden surface and a crisp exterior after the fries have cooled for a moment. If they are hot but pale or soft, shake again and give them a short additional check interval. If they brown too quickly, reduce the load next time rather than simply adding more time.

Safety and model guidance

Follow the frozen-food package and Ninja instructions for your regional AF400 model. Ninja's official AF400 guidance recommends frequent checks and shaking or turning when using Max Crisp for smaller frozen portions.
