A minimum baking temperature for chicken is 350 degrees Fahrenheit, according to Foster Farms. It's also important to check the temperature of the cooked chicken, which should be at least 165 degrees Fahrenheit.
A whole chicken weighing up to 5 pounds should roast for up to 1 1/2 hours at 350 degrees Fahrenheit to reach an internal temperature of 180 degrees Fahrenheit. Bone-in pieces take longer to cook, even when they are roasting at the same temperature. A bone-in chicken breast cooks for 30 to 40 minutes, and a boneless breast cooks for 20 to 30 minutes. A 6-ounce ground chicken patty cooks for 20 to 30 minutes.
