Chicken breasts should bake for about 30 minutes in the oven. The meat should be removed from the oven when its internal temperature reaches 160 degrees Fahrenheit. The chicken cooks a little more once it is removed.
Chicken breasts can be marinated in a mixture of oil, vinegar and spices or coated with ingredients like breadcrumbs or Parmesan cheese before being placed in the oven. Mustard and butter can also be used to flavor chicken. Chicken breasts are a significant source of protein and contain vitamin B6 and phosphorous. Chicken breasts are also low in sodium. The meat can be broiled, pan-fried, roasted and baked.
