Sous Vide Fish Temperatures
The lowest temperature most people use is 104°F (40°C). This just slightly heats the fish through, releasing some flavor but doesn’t really change the texture.
There are similar results at temperatures up to about 110°F (43.3°C). This fish is almost sushi-like.
From 110°F (43.3°C) to 120°F (48.9°C) the fish generally begins to have more pronounced texture changes, becoming slightly more flaky and firm, while still retaining a lot of moisture.
Above 120°F (48.9°C) the fish starts to become more and more flaky and starts to dry out.
The top temperature I usually cook any fish at is 132°F (55.5°C), though some people like it up to 140°F (60°C).
Warning: Only temperatures above 130°F (54.4°C) will pasteurize the fish, and only when held for several hours, something that is usually not done with fish.
I highly recommend only using fish you would feel comfortable eating raw, and not serving it to any immunodeficient people.
Different types of fish are best at different temperatures, so it’s usually best to look at a recipe for a specific fish, or a similar type of fish, when you are trying to determine what temperature is right for the preparation you are after.
