In most cases, chicken breasts are close in size, with some being notably larger than others if you’re buying them frozen.

Larger chicken breasts weigh about 7 oz. Should be cooked for about 20-25 minutes, depending on girth. Smaller cuts of chicken, around 5 to 6 oz., should be cooked for 18-20 minutes.

Since chicken is a naturally-lean piece of meat, you want to refrain from overcooking it.

Like many other types of meat, when they get cooked for too long, overcooked chicken can develop a tough texture. It can also have a stringy appearance.

Likewise, you want to avoid undercooking your chicken breasts, as well. Not only will this make them raw and unsafe to consume (experts recommend the ideal chicken breast temperature be 165 degrees Fahrenheit), but they can have a rubbery, dense appearance and texture.

When it comes to chicken, it’s one type of meat you can’t go under or overcook.

Is it Better to Bake Chicken at 350 or 400?

The answer to this question is that: it depends. The higher the temperature is, the faster your food will cook. However, that may not always be exactly what you’re looking for.

For example, the higher your oven’s temperature is, the more likely your chicken will develop crispy skin.

This is why it’s recommended to bake your chicken at a higher temp (usually between 400 and 425 degrees).

However, the longer your chicken bakes, the more likely it is to lose a little bit of moisture. This is why people opt to bake chicken between 350 and 375 degrees.

So, when it comes to determining which is better, the answer is that it depends on what your flavor preferences are. If you like crispy skin, then bake it at a higher temperature.

If you prefer a juicy piece of chicken, then bake it at a lower temperature. Or, if you want to get the best of both worlds, bake your chicken at 400 degrees, and then after 15 minutes, lower it to 350. This will give you crispy skin and some juiciness.
