About this calculator
This calculator estimates the time needed to roast a whole chicken in the oven at 180 °C, based on the weight of the bird. The calculation uses the formula: time = weight (kg) × 40 minutes + 20 additional minutes. The result is a total time in minutes, and the recommended internal temperature to ensure the chicken is fully cooked and safe to eat is 74 °C.
To use the tool, simply enter the weight of the chicken in kilograms. The calculator is useful for anyone planning to roast a whole chicken in a conventional oven, whether for a family lunch or a special dinner. Keep in mind that the actual time may vary depending on your oven and the position of the chicken on the rack.
Important precautions: always check the internal temperature of the chicken with a kitchen thermometer, especially in the thickest part of the thigh without touching the bone. Also, let the chicken rest for 10 to 15 minutes after removing it from the oven to allow the juices to redistribute, resulting in a more succulent meat.
Frequently asked questions
Can I use this calculator for boneless chicken or chicken pieces?
No, the formula is designed for a whole chicken. For pieces or boneless chicken, cooking time is different and usually shorter.
What if my oven doesn't reach exactly 180 °C?
Adjust the time according to the actual temperature. Hotter ovens cook faster; cooler ovens require more time. Use an oven thermometer for accuracy.
Do I need to preheat the oven before putting the chicken in?
Yes, preheat the oven to 180 °C before placing the chicken. This ensures even cooking from the start.
How can I tell if the chicken is cooked without a thermometer?
The safest method is to use a thermometer. Without it, check if the juices run clear when you pierce the thigh and if the meat pulls away from the bone easily, but this does not guarantee food safety.
Should I cover the chicken with foil during cooking?
Covering can prevent the skin from over-browning. If you prefer crispy skin, roast uncovered. If it's browning too fast, tent loosely with foil for the last 20 minutes.
