Question: how many ounces is a large boneless skinless chicken breast?
Answer: Boneless, skinless chicken breasts can be calculated to weigh between these amounts. An average chicken breast weighs between 3 to 8 ounces raw. The weight will decrease between 1 – 2 oz after being cooked. Sizes do vary with each chicken breast, but generally they don't get much larger than 12 oz.
