A 3 oz cooked skinless chicken breast portion has about 26 grams of protein. That estimate comes from cooked chicken breast values around 31 grams of protein per 100 grams. The number changes if you weigh the chicken raw, leave skin on, buy injected or seasoned chicken, or use breaded pieces.
3 oz Chicken Breast Protein Estimate
| Portion | Approximate protein | Important note |
|---|---|---|
| 3 oz cooked skinless chicken breast | About 26 g | Best everyday estimate for a cooked portion on a plate. |
| 100 g cooked skinless chicken breast | About 31 g | USDA FoodData Central cooked roasted chicken breast entry is near this value. |
| 3 oz raw chicken breast | Lower than a 3 oz cooked portion | Raw chicken loses water during cooking, so raw and cooked weights do not match. |
| Breaded or sauced chicken | Varies | Breading and sauce add weight, sodium, carbs, and sometimes fat. |
Cooked Weight vs Raw Weight
Protein estimates are easiest when you know whether the chicken was weighed raw or cooked. A piece that starts at 4 oz raw may weigh closer to 3 oz after cooking because moisture cooks off. That does not mean the protein disappeared; it means the cooked piece is more concentrated by weight.
What Does 3 oz Look Like?
A 3 oz cooked portion is a small serving, not a full large chicken breast. The most accurate method is a kitchen scale. Without a scale, think of a cooked portion roughly the size of a deck of cards, but use that only as a rough visual guide.
How to Use the Number
- Use the package Nutrition Facts label when you have one.
- Decide whether you are tracking raw weight or cooked weight and stay consistent.
- Account for skin, breading, marinades, sauces, and added sodium.
- Cook chicken to 165 degrees F for safety.
