What is specific to the AF400?

Ninja describes the AF400 as a 9.5L Dual Zone appliance with two separate 4.75L drawers. Its SYNC feature can align different programmes and finish times; MATCH copies settings when both drawers hold the same food. That makes it useful to plan food drawer by drawer rather than treating the full appliance as one large basket.

Use a cooking time as a starting point

  • One drawer, loose layer: check toward the early end of a broad food range.
  • One drawer, crowded layer: expect slower browning; shake or turn and allow more time if needed.
  • Two foods: set each drawer for its own food, then use SYNC if you want both ready together.
  • Frozen, breaded food: Ninja identifies Max Crisp for smaller amounts of frozen food and recommends checking and shaking or turning frequently.
For frozen fries, use 180–200°C for around 12–30 minutes only as a broad starting range.

Thickness, quantity and the selected programme move the finish point. Keep the fries in a loose layer, shake during cooking and follow the package where it differs.
