A whole, unstuffed chicken should be roasted for 25 minutes per pound at 350 degrees Fahrenheit. Chicken should be roasted until it reaches a minimum internal temperature of 170 degrees Fahrenheit.
A whole, stuffed chicken requires 20 additional minutes of roasting time. For darker, crispier skin, roast at 450 degrees Fahrenheit for the first 15 minutes, and then lower the oven temperature to 350 degrees for the remaining time. An alternative slow rotisserie technique is to roast a whole chicken at 250 degrees Fahrenheit for 75 minutes per pound. The oven should be preheated for 15 minutes. Test for doneness with a meat thermometer.
