Chicken Breast (Boneless)
at 425°F
20 min – 20 min Boneless Chicken Breasts take about 20 min – 20 min in a 425°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.
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.
Worth knowing before you start
- 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.

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.
