Sous Vide Chicken Breast Timer

Common uses for a sous vide chicken breast timer

Juicy chicken breast for salads and sandwiches
Batch cooking chicken for the week
Cooking chicken without drying it out
Holding chicken at temperature before service

Chicken is usually cooked to 74 °C (165 °F), the temperature at which pathogens are destroyed effectively instantly^[1]. That is a convenience, not a threshold: safety comes from a combination of temperature and time, and a lower temperature held for long enough achieves the same reduction in pathogens. This is the principle sous vide chicken relies on, and it is why a breast cooked at 60 °C for a sustained hold can be both safe and far juicier than one taken to 74 °C.

The clock has to cover two separate things. First, the centre of the breast must actually reach the bath temperature, which depends on thickness — roughly an hour for a 3 cm breast. Only then does the pasteurisation hold begin. Adding the two together is why published times look long relative to the pasteurisation figures alone, and why simply setting a timer for the lethality value is a mistake.

Read the safety guidance, not just this table

The times below are the widely published USDA FSIS Appendix A lethality values for poultry, which state how long the meat must be held at a given temperature once it has reached it. They are stated here as I have them and must be checked against the current edition of Appendix A before you rely on them, because the guidance is revised.

They also assume the meat is at that temperature throughout. Come-up time is additional, and a thicker or partly frozen piece takes considerably longer to get there than most people expect.

Texture changes with temperature, not just safety

At 60 °C chicken breast is very soft and noticeably moist, which some people find unfamiliar. At 65 °C it is firmer and closer to conventionally roasted. Both can be safe when held appropriately; the choice between them is texture.

If you are cooking for someone who is pregnant, elderly, very young or immunocompromised, use a higher temperature and a longer hold, and do not improvise around the guidance.

USDA FSIS Appendix A lethality times for poultry, stated as I have them and requiring verification against the current edition^[2]. These are hold times *after* the meat reaches temperature — add come-up time on top.

Poultry pasteurisation hold time by temperature
Bath temperature	Hold at temperature	Resulting texture
60.0 °C (140 °F)	about 35 min	Very soft, very moist
62.8 °C (145 °F)	about 11 min	Soft, moist
65.6 °C (150 °F)	about 4 min	Firmer, still moist
68.3 °C (155 °F)	about 1 min	Close to conventional
73.9 °C (165 °F)	effectively instant	Conventional, drier

Come-up time is additional: roughly 1 hour for a 3 cm breast to reach bath temperature before the hold begins.
Verify these values against the current USDA FSIS Appendix A before relying on them.
For anyone pregnant, elderly, very young or immunocompromised, use a higher temperature and a longer hold.

❓ Frequently Asked Questions

Is chicken cooked below 74 °C safe?

It can be, if held long enough. Safety comes from temperature and time together: 74 °C is the point where pathogens are destroyed effectively instantly, and lower temperatures achieve the same reduction over a sustained hold. That is the principle sous vide relies on — but follow published lethality guidance rather than guessing.

How long does sous vide chicken breast need?

Two things added together: about an hour for a 3 cm breast to reach bath temperature, then the pasteurisation hold for that temperature — roughly 35 minutes at 60 °C, or about 4 minutes at 65.6 °C. Setting a timer for the hold time alone is a mistake, because the meat has not reached temperature yet.

Why does 60 °C chicken feel strange?

It is much softer and moister than chicken most people have eaten, because it has not been taken to a temperature that tightens the proteins as much. It is a texture difference, not a sign of undercooking, provided the hold time was met. At 65 °C it comes out closer to conventionally roasted.

Does thickness change the time?

Yes, substantially, and it affects come-up time rather than the hold. A thick breast takes considerably longer to reach bath temperature than a thin one, and the pasteurisation clock does not start until it has. Partly frozen chicken takes longer still.

Can I cook sous vide chicken for anyone?

Be cautious. For someone pregnant, elderly, very young or immunocompromised, use a higher temperature and a longer hold, and do not improvise around published guidance. This page describes the principle; it is not a substitute for the current food safety guidance itself.

Do I need to sear sous vide chicken?

Only if you want colour and a firmer surface — it comes out pale, since no browning happens at these temperatures. Dry it thoroughly and sear briefly in a very hot pan. The sear is cosmetic and textural here, not a safety step.
