Does chicken really have to hit 165°F?

165°F is real, but it's the instant-kill number — the temperature where salmonella dies in under a second. Food safety is actually a function of temperature AND time: chicken held at 150°F for about three minutes reaches the same safety as 165°F instantly. The government publishes these tables; restaurants cook from them.

Why care? Because breast meat at 165°F has squeezed out a lot of its moisture — that's the chalky, stringy chicken of childhood. At 150–155°F, held there while it rests, it's just as safe and dramatically juicier.

In plain English for a weeknight: pull breasts at 155°F, let them sit five minutes before slicing (they were going to rest anyway), and you're covered. Thighs are different — they're not unsafe at 165°F, they're actually BETTER at 175°F+, because their connective tissue needs the heat to melt.

None of this works by guessing. A $15 instant-read thermometer is the entire trick — it converts anxiety into a number. If you're nervous, cook to 165°F; the chicken will still be better than takeout. But know that the extra 10 degrees is a safety margin you're choosing, not a law of nature.
