How to Roast a Chicken by Weight and Temperature
Roasting time for a whole chicken depends on its weight and the oven temperature, not a single fixed number, and using time alone as your guide is how you end up with dry breast meat or a pink thigh joint. The most reliable method combines a weight-based time estimate with a thermometer check near the end.
Steps
- 1Pat the chicken dry with paper towels, inside and out, and let it sit at room temperature for 30-45 minutes before roasting.
- 2Preheat the oven to 425°F (220°C) for a shorter, crispier roast, or 375°F (190°C) for a slower, more even one.
- 3Season generously inside the cavity and under the skin, then truss the legs together with kitchen twine so the bird cooks evenly.
- 4Place the chicken breast-side up on a roasting rack set inside a pan.
- 5At 425°F, roast about 13 minutes per pound: a 4-pound chicken takes roughly 55-65 minutes, a 5-pound chicken 65-75 minutes, and a 6-pound chicken 75-90 minutes.
- 6At 375°F, roast about 20 minutes per pound plus 15 minutes: a 4-pound chicken takes roughly 95-105 minutes, and a 5-pound chicken 115-125 minutes.
- 7Start checking the internal temperature about 15 minutes before the estimated time is up by inserting a thermometer into the thickest part of the thigh, avoiding the bone.
- 8Pull the chicken when the thigh reads 165°F (74°C); the breast will typically read a few degrees higher at that point since it cooks faster.
- 9Tent the chicken loosely with foil and let it rest for 10-15 minutes before carving so the juices redistribute instead of running out onto the cutting board.
Common mistakes
- Trusting time over temperature: oven calibration, chicken shape, and starting temperature all shift the actual roasting time by 10-20 minutes in either direction.
- Checking the breast instead of the thigh: the thigh is the last part to reach a safe temperature, so it's the accurate spot to test doneness.
- Skipping the rest: carving immediately releases most of the juices onto the board instead of back into the meat.
- Roasting a cold chicken straight from the fridge: a cold bird takes longer to cook through and browns unevenly by the time the center is done.

FAQ
How long does it take to roast a 5-pound chicken?
At 425°F, about 65-75 minutes. At 375°F, about 115-125 minutes. Confirm with a thermometer rather than relying on time alone.
What internal temperature means a chicken is done?
165°F (74°C) in the thickest part of the thigh, measured without touching bone. The breast usually reads slightly higher by the time the thigh hits that mark.
Is it better to roast chicken at a higher or lower temperature?
425°F gives crisper skin and a shorter cook time but requires closer attention near the end to avoid overcooking the breast. 375°F cooks more evenly with less risk of drying out but takes longer.
Why is my chicken still pink near the bone after the recommended time?
Bone marrow can leach a pink tint into nearby meat even when the chicken is fully cooked, but color alone isn't a reliable doneness test. Always confirm with a thermometer reading of 165°F in the thigh.
Should I roast a stuffed chicken the same length of time as an unstuffed one?
No, a stuffed chicken needs roughly 20-30 extra minutes because the stuffing insulates the cavity and slows heat penetration to the thigh.
