A typical cooked, skinless chicken breast contains about 31 to 32 grams of protein per 100 grams (3.5 ounces)

. For example:

• A 100-gram serving of cooked chicken breast provides approximately 31 grams of protein

• A cooked chicken breast weighing around 174 grams contains about 56 grams of protein, which aligns with roughly 32 grams per 100 grams

• A 3-ounce (85 grams) cooked chicken breast has about 26 grams of protein

If you consider a whole average-sized boneless, skinless chicken breast (about 170–180 grams), it typically contains around 50 to 56 grams of protein

. In summary, the protein content scales with the size of the chicken breast, but per 100 grams cooked, expect roughly 31–32 grams of protein. Raw chicken breast has slightly less protein per 100 grams due to water content, around 22 to 26 grams, but cooking concentrates the protein amount per gram
