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 totalling 440g, not a range. Recorded as published.
- Assuming
- 440g in total, 4 pieces, From frozen
- In
- Multicooker with air fry
- Loaded
- Single layer, pieces not touching
- Preheat
- Yes, before the food goes in
- Result
- Crisp outside, moist inside
Preparation
Straight from the freezer on a raised crisper surface. No oil is added.
No oil needed.
How to load the basket
Single layer, pieces not touching. The reference condition. Air reaches every surface, and times are the shortest the food will achieve.
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 with a stated quantity, a stated preparation and an oil quantity, from the manufacturer's own guide for this appliance. 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
These apply to every food and every air fryer, so they are here once rather than repeated under each state above. They come from Electrical Safety First, from UK product-safety notices and from the manufacturers’ own manuals.
- Plug an air fryer directly into a wall socket. Do not run one from an extension lead.
- An unusual smell, an unusual noise, or scorch marks on the plug mean stop using it and contact the manufacturer.
- Do not overfill. Food touching the heating element is a fire risk, not a cooking problem.
- White smoke from fatty food is usually normal. Black smoke means unplug it immediately.
- Do not leave an air fryer running unattended.
- Leave clear space above and around the appliance, and never cover the air intake or the outlet.
- Aim for a golden yellow colour or lighter on starchy foods such as chips and roast potatoes, rather than a darker brown.
- Buy from a reputable retailer rather than a third-party marketplace seller.
- Clean the drawer, the plate and the element after use. Accumulated grease is what smokes, and then what burns.
- Register the appliance with its manufacturer. It is how a recall reaches you.
- Do not rely on the appliance's own thermal protection. A UK recall was issued because it did not operate.
Each links to its own page, with what it means in practice, what to do if it has already happened, and the source it comes from. Every safety rule AirfryerHQ holds.
Why breaded fish products behaves this way
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. This measures yours — and it is the single change that fixes most dry battered fish fillets.
- 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
The ways battered fish fillets specifically tends to fail, 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.
