Chicken breast is a staple for high-protein meals, but the protein per ounce changes depending on whether you weigh it raw or cooked. This guide gives you the exact numbers for raw, cooked, and shredded chicken breast, plus how to portion it accurately for your meal prep.
Ingredients
- 1 boneless, skinless chicken breast (about 6 oz / 170 g raw)
- Optional: 1 tsp (5 ml) olive oil for cooking
- Optional: salt and pepper to taste
Instructions
- Weigh the raw chicken breast on a kitchen scale. Note the weight in ounces or grams.
- If cooking, pat the chicken dry with paper towels. Season with salt and pepper if desired.
- Cook the chicken using your preferred method (grill, bake, or pan-sear) until the internal temperature reaches 165°F (74°C) as measured with a food thermometer (USDA FSIS safe minimum for poultry).
- Let the cooked chicken rest for 5 minutes before slicing or shredding.
- Weigh the cooked chicken again. Use the numbers below to calculate protein.
Tips
- Raw vs. cooked weight: Raw chicken breast is about 80% water. Cooking removes moisture, so 4 oz (113 g) raw will shrink to about 3 oz (85 g) cooked. Protein content stays the same, but the concentration per ounce increases.
- Use a food scale: For accurate macros, always weigh your chicken. A typical serving is 4 oz (113 g) raw or 3 oz (85 g) cooked.
- Don’t overcook: Chicken breast dries out quickly. Use a meat thermometer and pull it at 165°F (74°C) for juicy, safe meat.
- Shredded chicken: Shredded chicken packs loosely, so 1 cup of shredded chicken weighs about 5 oz (140 g) and contains roughly 43 g of protein.
Serving Suggestions
Use your measured chicken breast protein as a topping for salads, in wraps, or alongside rice and vegetables. A 4 oz (113 g) raw serving (about 3 oz cooked) provides roughly 26 g of protein, making it easy to hit your daily target.
Variations
- Marinated chicken: Marinate in lemon juice, garlic, and herbs for 30 minutes before cooking. This adds flavor but does not change protein content.
- Thighs vs. breasts: Chicken thighs have slightly less protein per ounce (about 24 g per 4 oz raw) but more fat and flavor.
- Ground chicken: Ground chicken breast has the same protein density but is easier to portion into patties or meatballs.
Storage and Reheating
Refrigerate cooked chicken in an airtight container within 2 hours of cooking. It will keep for 3–4 days. Reheat gently in the microwave (covered, with a splash of water) or in a skillet over medium heat until warmed through to 165°F (74°C). For longer storage, freeze cooked chicken for up to 3 months; thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
How much protein is in 1 oz of raw chicken breast? One ounce (28 g) of raw boneless, skinless chicken breast contains about 6.5 g of protein. This is based on USDA data for raw chicken breast.
How much protein is in 1 oz of cooked chicken breast? One ounce (28 g) of cooked chicken breast (without skin) contains about 8.7 g of protein, because cooking removes water and concentrates the protein.
Is the protein the same whether I weigh raw or cooked? The total protein is the same, but the weight changes. If you weigh raw, use 6.5 g per ounce; if you weigh cooked, use 8.7 g per ounce. For example, 4 oz raw (113 g) has about 26 g protein, and after cooking it weighs about 3 oz (85 g) and still has 26 g protein.
Do I need to weigh chicken with or without skin? Weigh without skin and bones. Skin adds fat and calories but very little protein, so it skews your protein-per-ounce calculation.
How much protein is in a typical chicken breast? A medium chicken breast (about 6 oz / 170 g raw) provides roughly 39 g of protein. A larger 8 oz (227 g) breast gives about 52 g.
Can I use this information for meal prep? Yes. Cook a batch of chicken, then weigh portions. For a 30 g protein serving, you need about 4.6 oz raw or 3.4 oz cooked chicken breast.
