How Long to Cook Chicken in the Oven?

How long you will cook chicken in the oven depends on what you are cooking. If it is a whole chicken, say 3.5 to 4 pounds, it will take 1 1/4 to 1 3/4 hours in a 375 degree oven. Pieces of chicken can be broiled in the oven for 12 to 30 minutes in a medium-hot oven.
