Chicken Breast (Boneless)
cooking times
The answer
20 min – 25 minat 400°F
At the most common temperature, 400°F, boneless chicken breasts takes about 20 min – 25 min. Pick your temperature below for the full chart. Done is always 165°F internal.

USDA safe zone — 165°F and above
Done is a temperature, not a time. Every figure on this page is a planning range; the green band is the only part that decides. For boneless chicken breasts it opens at 165°F and a 5-minute rest.

How this is worked out
- Anchor. Start from what USDA FSIS publishes for boneless chicken breasts — its safe minimum internal temperature of 165°F, and the FSIS roasting timetable where one exists for this cut.
- Rate. Convert the anchor into a planning rate at 400°F: a fixed published range, cross-checked against at least three independently published sources.
- Scale. This cut is timed by piece, not by weight, so the range is published as-is and widened to cover source disagreement rather than averaged.
- First check. The first thermometer reading is set at 85% of the low end of the range — early enough that an under-reading costs nothing and a late one cannot cost the meal.
- Gate. The time is only a plan. It is not done until a food thermometer reads 165°F in the thickest part, then rests about 5 minutes. Time never overrides temperature on this site.
- Round. Every printed figure is rounded to the nearest 5 minutes; precision beyond that would be invented.
plan_range = published range at 400°F
first_check = plan_low × 0.85
DONE ⟺ internal_temp ≥ 165°F AND rest ≥ 5 min
(USDA FSIS — the gate, not the clock)

When it is 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.
Sizing: Times are for typical 6–8 oz boneless, skinless breasts. Very large (10 oz+) breasts add 5–10 minutes; thin-sliced cutlets can finish in half the time.

What the ledger does not tell you
- Thickness matters far more than weight — a pounded, even breast cooks faster and stays juicier than a thick teardrop shape.
- Pull at 162–163°F and rest 5 minutes; carry-over heat finishes the job at 165°F without the chalky texture of an overshot breast.
- Bone-in, skin-on breasts run 10–15 minutes longer than these times.
The clock tells you when to start looking. The thermometer tells you when to stop.
