Fish Cooking Time
Free Fish Cooking Time calculator with clear step-by-step results.
About Fish Cooking Time
Fish cooks by thickness, not by weight - a thin wide fillet and a thick small one of equal mass need very different times. Each method has its own minutes-per-centimetre rate, cooking from frozen adds roughly half again, and pan and grill times are split across two sides.
Formulas
Cooking time
Minutes = thickness cm x minutes per cm for the method
From frozen
Frozen time = thawed time x 1.5
Worked example
With the default values below, Fish Cooking Time returns Total cooking time of 12.0. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- Food safety guidance: fish should reach 63 C throughout, and lower-temperature techniques require time-at-temperature control. People who are pregnant, immunocompromised or elderly should avoid undercooked and raw fish.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions
How do I know when it is done?
The flesh turns opaque and flakes with light pressure, and the internal temperature reaches about 63 C. Sous vide is deliberately lower because the long hold at temperature achieves equivalent safety.
Does this work for whole fish?
Measure thickness at the deepest point behind the head rather than average it, and add a few minutes because the cavity slows heat transfer.
