Why Bake Chicken Breast In the Oven?

Baking in the oven is a simple and easy way to cook a chicken breast. You can bake chicken breasts, with or without the skin, at 400 degrees Fahrenheit. This is a little higher than normal baking temperature, so it’s often referred to as roasting rather than baking. Chicken is typically roasted in the oven for 20 to 30 minutes but this can vary based on the amount of chicken you’re cooking and how thick the breasts are. The most important factor, regardless of time spent in the oven, is the internal temperature. The thickest part of a chicken breast should reach at least 165 degrees Fahrenheit. The juices from the chicken should also run clear.

Safety Precautions While Cooking Chicken Breast

Raw chicken may contain Salmonella bacteria so this is an important step to prevent infection. Another important tip to avoid foodborne illness? Rinse the chicken breast and pat dry with a paper towel. Also, do not prepare any other food ingredients on the surfaces that came in contact with the raw chicken before thoroughly disinfecting and/or washing them.

What are the Health Benefits of Baked Chicken Breast?

Chicken breasts are a good source of animal protein and the breast meat has the lowest fat content of any part of the chicken. Humans need to eat protein every day. Why? This macronutrient is present in every cell of our body. Protein is made up of amino acids which are the building blocks that help our tissues grow. This includes our muscles, skin, nails, and hair.

We’re unable to naturally produce some amino acids so they need to be consumed through food. Amino acids that can only be acquired by eating food are called essential amino acids. Protein is found in many different foods, including meat, poultry, fish, dairy, beans, legumes, nuts, seeds, and whole grains. Protein from animal sources, like chicken breast, provide all of the essential amino acids.

Cooking Boneless Chicken Breast FAQs

What if I buy chicken breast but am unable to use it right away? Cook or freeze poultry within two days of the sell-by date. If the poultry is uncooked, whole or in pieces, you can store it in a refrigerator (36° to 40°F) for 1 to 2 days, or in the freezer (0°F or colder) for 12 months (whole chicken) or 9 months (chicken pieces).

Can you cook a frozen chicken breast? According to the United States Department of Agriculture, the answer is yes, but under one condition. Frozen chicken can be cooked directly in the oven or on the stove. The cooking time may be about 50 percent longer. You should not cook frozen chicken in a slow cooker or in the microwave — it must be fully thawed first.

What’s the best way to thaw chicken breast? There are three safe methods you can follow: In cold water, in the refrigerator or in the microwave. Boneless chicken breasts, bone-in parts, and whole chickens may take 1 to 2 days or longer to thaw. Once the meat thaws, it can be kept in the refrigerator for an additional day or two before cooking. During this time, if the chicken is not cooked, it can safely be refrozen.

Does cook time change when using bone-in chicken breast? Yes, it typically takes about 10 additional minutes to cook chicken breast on the bone. Again, the most important factor, however, is that the chicken reaches an internal temperature of at least 165 degrees Fahrenheit.
