Question: how many ounces does a chicken breast weigh?
Answer: 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. Today's poultry breasts are larger and 8 – 10 oz sizes are very common in grocery stores.
