One manufacturer prints fifteen to twenty-five minutes at 180–200°C for a 300-400g fish, and the size that fits is the real constraint.

Preparation

How to tell it is done

  • The flesh at the thickest part lifts cleanly from the backbone
  • The eye has gone opaque white

What this does not cover

  • Published by the manufacturer for this model. It is evidence about this appliance and is not general advice.
  • The word fresh is the table's and not the row's: the manual prints above this table that its cooking times are guidelines for fresh ingredients, and this row's own title names no state.
  • This machine's two pans are not interchangeable. The figure is for the big pan; the small pan has its own table.
  • The row prints each fish's weight as a band of around 300-400g. It is held as that band, with the three fish it prints, and no total is worked out from the two.

Chilled

Cooked as fresh: use the fresh figures above. Raw food sold chilled is the fresh state under another name, and the charts those figures come from start from fridge-cold.

Defrosted

Cooked as fresh: use the fresh figures above. Once it is defrosted all the way through it is at fridge temperature and cooks as fresh does; no chart read for this catalogue tells the two apart.

Manufacturer figures with no state given

This is a published figure for one named machine. The manufacturer does not say whether this is fresh or frozen. So it is kept apart from the figures above, and not used as the answer for any of them.

  • Philips Essential Airfryer HD9252/91 4.1L: 200°C for 15–20 min

    Published for one whole fish of around 300–400g.

What usually goes wrong

Cooked at the tail and raw at the shoulder, because a whole fish is thickest right behind the head and that is the part nobody checks. Slashing the thickest part twice on each side does more than any change to the time.

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.

White fish in fast-moving hot air

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.
