Chicken Thighs (Bone-In)
at 400°F
30 min – 40 min Bone-in Chicken Thighs take about 30 min – 40 min in a 400°F oven. Done is 165°F on a food thermometer, plus a 5-minute rest — never the clock alone.
When is it actually done?
165°F internal The USDA FSIS safe minimum internal temperature for this cut is 165°F, followed by a rest of about 5 minutes. The clock estimates; the thermometer decides. Every time on this page is a planning range, not a doneness test.
Pull temperature vs safe temperature: 165°F is safe, but thigh meat is at its best at 175–185°F — the extra time melts the connective tissue that makes dark meat taste dry-yet-rubbery when it is merely 'done'.
Sizing: Times are for typical 5–7 oz bone-in, skin-on thighs. Boneless thighs finish 8–12 minutes sooner.
Worth knowing before you start
- Thighs are forgiving — an extra 10 minutes rarely hurts them, which is why they are the right cut for a crowded oven.
- Roast skin-side up on a rack for skin that crisps instead of steaming.

What internal temperature is bone-in chicken thighs done at?
165°F, measured with a food thermometer in the thickest part, then rested about 5 minutes. That is the USDA FSIS safe minimum. 165°F is safe, but thigh meat is at its best at 175–185°F — the extra time melts the connective tissue that makes dark meat taste dry-yet-rubbery when it is merely 'done'.

It is one of 3 temperatures this site publishes for this cut (375°F, 400°F, 425°F). It is the most commonly used.
Where these numbers come from
Ranges are anchored to USDA FSIS published timetables where they exist, and derived from that anchor plus cross-checked published sources where they do not — widened to cover the disagreement between sources rather than split down the middle. The full reasoning is on the method page. If a figure here looks wrong, say so — corrections are prioritised.
