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 flesh flakes when a fork is turned in it
  • Opaque with no translucent core

In a different appliance

  • Dual-basket air fryer: 200°C for 10 min

    A single published figure for a stated 225g fillet an inch thick.

  • Multicooker with air fry: 180°C for 8–12 min

    Published range, brushed with oil and seasoned.

  • Combination microwave with air fry: 220°C for 20–25 min

    Published range for 2–4 fillets totalling 225–450g, stated as less than an inch and a half thick.

  • Multicooker with air fry: 260°C for 4–6 min

    Fillet thickness, for six published 125g cod or haddock fillets. The chart does not distinguish the two species.

  • Basket air fryer: 160°C for 22–25 min

    Fillet count, for one to three published fillets of around 200g in a single layer. The low temperature is the notable part — 160°C where most rows in the same table are 180 or 200.

  • Basket air fryer: 160°C for 21–30 min

    Fillet count, for one to five published fillets of around 200g in a single layer.

Applies to
Specific to this model
Why this rating
A preset the manufacturer programmed into the appliance and published with both its default temperature and its default time. It is the manufacturer's own starting point for that food in that machine, which is real published guidance and is weaker than a chart row because no quantity comes with it.

What this does not cover

  • Published by the manufacturer for this model. It is evidence about this appliance and is not general advice.
  • NO QUANTITY IS PUBLISHED. A preset is a starting point the manufacturer chose, not a validated time for a stated weight, and it cannot be checked against the food in front of you the way a chart row can.

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

260°C (500°F) for 6–8 min

Fillet thickness, for six published 90g cod fillets from frozen. Only two minutes more than the fresh row, because the fillets are thinner.

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 contact grill plate rather than a perforated basket. Heat reaches the food by conduction from the plate as well as by airflow, which is a different mechanism from air frying and transfers poorly to a basket machine.

Leftover (reheating)

Before anything else

From national food-safety authorities, not from us. These take precedence over any cooking time below.

Requirement — Food safety (microbiological)

Cool cooked food and get it into the fridge within one to two hours, keep the fridge between 0 and 5°C, and eat leftovers within 48 hours.

How to tell, without a thermometer

  • There is no sensory test for this rule, and that is the point: food held too long at the wrong temperature does not necessarily look, smell or taste different

If it has not got there: Throw it away. This is the one rule in this catalogue where the remedy is not 'cook it longer', because cooking does not reverse it.

Important: Cooked rice is the sharpest case: Bacillus cereus toxins form at room temperature and survive reheating. Rice left out for more than an hour goes in the bin.

Requirement — Food safety (microbiological)

Reheat leftovers until steaming hot all the way through, and only reheat them once.

Target: 70°C in the thickest part, or an equivalent from the table below.

How to tell, without a thermometer

  • Steam rising from the centre, not just the edges
  • The middle is hot to the touch, tested after removing it from the appliance

If it has not got there: Keep going, and break dense food up or spread it out so the heat can reach the middle. If it will not heat through evenly, a microwave to get the centre hot followed by the air fryer to crisp the surface is a better tool for the job than the air fryer alone.

Important: Cooked rice and pasta left at room temperature can develop Bacillus cereus toxins that reheating does not destroy. If cooked rice has been out of the fridge for more than an hour, discard it rather than reheating it.

Each of these moves the outcome in a known direction, and most cost you something. The trade is stated so you can decide whether you want it.

To know whether this is the right appliance
This is the clearest case in the catalogue where an air fryer is not the right tool. Cooked white fish has no fat to lose and dry moving air takes what water is left — a covered dish in a low oven, or a microwave on a low setting, does it better.
To be sure it is safe rather than just warm
Go by the food and not the clock. It has to be steaming hot the whole way through, and the middle of a dense portion lags a long way behind its surface in an air fryer.

What this does not cover

  • THE TIME ON THIS RECORD IS NOT SOURCED. Five manufacturers publish a reheating temperature and not one names a food, a quantity or a time for a named dish. The temperature sits inside their band; the time is AirfryerHQ's estimate and has not been measured.
  • Reheating is governed by the food-safety rule above rather than by this figure. Steaming hot throughout is the requirement; the time is a guide to getting there.

    AirfryerHQ's interpretation of what it says

    Citation checked — the document exists and is described correctly

Chilled

No time or temperature for this, and not by accident

White fish fillet is sold and cooked chilled, so the question is a real one. AirfryerHQ holds no published figure for it: not one of the manufacturer manuals read for this catalogue gives a chart row for this food in this state.

We are not going to produce one by adjusting the fresh figure above. A time arrived at that way would appear on this page looking exactly like a time somebody measured, and you would have no way to tell the difference.

What we do hold for white fish fillet: fresh, from frozen, leftover (reheating). Those are a different question, not a starting point for this one.

Defrosted

No time or temperature for this, and not by accident

White fish fillet is sold and cooked defrosted, so the question is a real one. AirfryerHQ holds no published figure for it: not one of the manufacturer manuals read for this catalogue gives a chart row for this food in this state.

Same reason as above: a figure adjusted from one we do hold would be indistinguishable from one somebody measured.

What we do hold for white fish fillet: fresh, from frozen, leftover (reheating). Those are a different question, not a starting point for this one.

What usually goes wrong

Dry and chalky, from about ninety seconds of overcooking. White fish has no fat and no connective tissue, so there is nothing between perfectly cooked and ruined. It also sticks: the protein bonds to a bare crisper plate and the fillet comes out in pieces, which is the second-commonest complaint about it.

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.

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 white fish behaves this way

White fish is around eighty per cent water held in short muscle fibres with very little connective tissue, so it needs almost no time and has no margin at all. The moment the fibres contract, the water is expelled and the fillet goes from translucent to chalky. It also has no fat to buffer the surface, so hot dry air dries the outside before the inside is warm — which is why nearly every published time for it is under fifteen minutes and why the flake test matters more than the clock.

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 white fish fillet.
  • 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.
  • Reheating leftoversA different question governed by a different rule — steaming hot throughout, and only once.
  • Why published timings differIf another chart says something else, this is usually why — and which one to believe.

If it went wrong

The ways white fish fillet specifically tends to fail, each with the fastest thing to check first.

  • Food comes out dry — The appliance works by removing surface water, so drying food out is its failure mode rather than an accident.

  • Salmon fillet — A different cooking problem with a different answer.
