Fresh vs frozen
Cooking from frozen takes roughly 50% longer and cooks less evenly. These estimates are for a medium.
Fresh / refrigerated
22–26 min
From frozen
33–39 min
USDA guidance allows frozen poultry and meat to be cooked without thawing; allow extra time and never thaw at room temperature.
How to know when it's done
Time is an estimate — temperature is the truth. Check the thickest part with an instant-read thermometer: chicken breast is safely done at 165°F / 74°C.

Frequently asked questions
Is chicken done at 165°F (74°C)?
Yes. USDA guidance is that chicken is safe to eat once it reaches an internal temperature of 74°C (165°F), measured at the thickest part. Time estimates get you close; the thermometer is the final check.
Can I cook chicken breast from frozen?
Yes, but it takes about 50% longer and cooks less evenly. USDA says frozen chicken is safe to cook (never thaw at room temperature) — check the internal temperature in a few spots.
Should I rest chicken after cooking?
Rest 3–5 minutes loosely covered so the juices redistribute and the temperature equalizes.
