How Long to Roast a Whole Chicken

A 3 to 4 pound whole chicken roasts in about 1 1/4 to 1 1/2 hours at an oven temperature of 350°F (175°C). This is the USDA’s guideline for a common broiler-fryer size, and it is a useful starting point for planning a meal.

However, roasting time is always an estimate. The actual time your chicken needs will depend on its exact weight and whether it is stuffed. The most reliable way to determine doneness is not by a clock, but by using a food thermometer to check the internal temperature.

Good to know

• Check the innermost part of the thigh and wing and the thickest part of the breast
• Rest the bird before carving

How chicken size and stuffing affect timing

The primary factors that change the roasting time for a whole chicken are its weight and the presence of stuffing. The provided time chart shows estimates for different sizes of chickens, from small Cornish hens to larger roasting hens.

• Weight: A larger, heavier bird has more mass to heat, so it will take longer to cook through than a smaller, lighter one. A 5 to 7 pound roasting hen, for example, needs about 2 to 2 1/4 hours, which is longer than a 3 to 4 pound bird.
• Stuffing: A stuffed chicken requires more time in the oven. The stuffing acts as a dense mass inside the bird’s cavity, slowing down heat penetration. The USDA suggests adding 15 to 30 minutes to the roasting time for a stuffed bird. It is critical that the center of the stuffing also reaches a safe temperature of 165°F (74°C), as it can absorb raw juices from the chicken.

How to tell when chicken is done

Using a food thermometer is the only way to be certain that chicken is cooked to a safe temperature. The USDA states that all poultry, including whole chicken, must reach a minimum internal temperature of 165°F (74°C) to be safe to eat. Checking the temperature in the right places is key for an accurate reading.

Insert the thermometer into the thickest parts of the chicken, being careful not to touch any bone, which can give a false high reading. The USDA specifies checking three locations for a whole bird:

• The innermost part of the thigh.
• The innermost part of the wing.
• The thickest part of the breast.

When all three spots register at least 165°F (74°C), the chicken is ready to be removed from the oven. Clear juices are not a reliable indicator of doneness; always rely on a temperature reading.

Tips for roasting a whole chicken

A few basic techniques can help produce a more evenly cooked chicken. Since ovens can have hot spots, rotating the roasting pan partway through cooking can help all sides brown equally.

Bringing the chicken to a more even temperature before it goes into the oven can also promote even cooking. A bird that is very cold in the center and warmer on the outside may result in an overcooked exterior by the time the inside is done.

Finally, after the chicken reaches 165°F (74°C) and is removed from the oven, it is important to let it rest before carving. A rest period allows the juices to redistribute throughout the meat, resulting in more tender meat. If you carve it immediately, the juices will run out onto the cutting board.
