From frozen
Before anything else
From national food-safety authorities, not from us. These take precedence over any cooking time below.
Requirement — Food safety (microbiological)
Food cooked from frozen must reach the same core temperature as the same food cooked fresh — the frozen centre is the last thing to get there.
Target: 70°C in the thickest part.
How to tell, without a thermometer
- No ice or cold spot at the centre when the thickest piece is cut open
- Steaming hot throughout, tested in the middle rather than the edge
If it has not got there: Reduce the temperature by 10–20°C and give it longer. A lower set point lets the centre catch up before the surface passes the point of no return, and it is the single most useful adjustment for cooking from frozen.
Important: If the packaging says the product must be thawed before cooking, follow it. That instruction exists because the manufacturer has tested cooking it from frozen and it did not reach temperature reliably.
The quick answer
200°C (392°F) for 11 min
A single published figure of eleven minutes for four fillets in batter weighing 440g between them, not a range.
- Assuming
- 440g in total, 4 pieces, From frozen
- In
- Multicooker with air fry
- Published for
- Ninja Foodi MAX Health Grill & Air Fryer AG551UK
- Preheat
- Yes, before the food goes in
- Result
- Crisp outside, moist inside
Preparation
Frozen, with no oil and no preparation, as the row prints.
No oil needed.
While it cooks
At about 6 minutes: Shake the food
The chart tells the owner to shake or toss the food often and to check it frequently. It prints that beside the whole chart, not against this row, and gives no single point for it.
How to tell it is done
- The batter is uniformly gold and firm
- The fish flakes cleanly when a fork is turned in it
Where these figures came from — from frozen
- Applies to
- Specific to this model
- Why this rating
- A published row from the manufacturer's own guide for this appliance, held as the chart prints it: its amount, its preparation and its oil where it gives them, and nothing where it does not. Quantity is what makes a chart row checkable against the food in front of a reader, and this chart states one for almost every row.

What this does not cover
- Published by the manufacturer for this appliance. It is evidence about this machine and is not general advice.
- This is a lidded cooking pot rather than a shallow drawer. Depth affects how much fits in one layer, and the quantity in the chart assumes the crisper basket.

What usually goes wrong
Soggy underneath. Batter is a smooth continuous shell rather than a porous crumb, so any moisture that cannot escape collects where the fillet meets the basket — which is why a raised crisper plate matters more for battered fish than for anything else in this section.
Running the appliance safely
The rules for the machine are the same whatever is in it: plug it straight into a wall socket, leave clear space round it, do not overfill it, do not leave it running unattended, and unplug it at black smoke or an electrical smell. They are set out once, each with its source and what to do if it has already happened, and not repeated on every food. Every rule for running an air fryer safely.
Breaded fish products in fast-moving hot air
The breadcrumb layer is dry and porous and already contains oil from the factory par-fry, so it crisps in moving air with nothing added — which is exactly what an air fryer is good at and exactly what a domestic oven is not. The fish inside is already cooked or part-cooked and is only being brought up to temperature, so the whole exercise is about the crumb. Overcrowding is the failure: the crumb needs air on all sides and a heaped basket steams it.
Where to go from here
The pages that answer the questions this one tends to raise.
- Using a thermometer, and where to put itThe times above are for a piece that is not the one you are holding. A probe measures yours, which is what the safety rule on this page asks for.
- How food actually gets crispyWhy patting it dry, spacing it out and a little oil are all the same instruction — so you can apply it when a page runs out.
- Cooking from frozenUsually cooler and longer than the same food fresh, and never worked out from the fresh figure.
- Why published timings differIf another chart says something else, this is usually why — and which one to believe.
If it went wrong
What tends to go wrong with battered fish fillets, each with the fastest thing to check first.
- The breading or coating falls off — Usually the fan, and usually because the coating was never dry enough to set before the airflow got to it.
