A cooked, skinless chicken breast contains about 31 grams of protein per 100 grams, making chicken one of the most protein-dense foods available. A single full breast (around 172 grams) packs roughly 54 grams of protein, which covers nearly the entire daily recommended intake for most adults.
Protein by Cut of Chicken
Not all cuts are created equal. The protein content varies depending on which part of the bird you’re eating, though every cut delivers a substantial amount. All values below are for cooked, skinless, boneless meat.
- Breast: 31 grams of protein per 100 grams. One full breast (172 g) provides about 54 grams.
- Wing: 30.5 grams per 100 grams. A single boneless wing (21 g) has about 6.4 grams.
- Drumstick: 28.3 grams per 100 grams. One boneless drumstick (44 g) gives you roughly 12.4 grams.
- Thigh: 26 grams per 100 grams. One boneless thigh (52 g) contains about 13.5 grams.
The breast leads the pack, but the gap between cuts is smaller than most people expect. Wings actually come in a close second per 100 grams. Thighs sit at the lower end because they carry more fat relative to their weight, which slightly dilutes the protein concentration. In practice, though, you’d need to eat several wings to match the total protein from a single breast simply because individual wings are so small.
How One Chicken Breast Fits Your Daily Needs
The federal recommended dietary allowance for protein is 46 grams per day for adult women and 56 grams per day for adult men. That means a single cooked chicken breast gets a woman to about 117% of her RDA and a man to about 96%. Even a modest portion, half a breast, covers roughly half your daily minimum.
These RDA numbers represent the minimum to prevent deficiency, not necessarily the optimal amount. People who exercise regularly, are trying to build muscle, or are over 50 often benefit from higher intakes, sometimes in the range of 1.2 to 2.0 grams per kilogram of body weight. For a 70 kg (154 lb) person aiming for 1.6 g/kg, that’s 112 grams of protein per day. Two chicken breasts would get you there, with room from other meals to fill the gap.
Skin On vs. Skin Off
Leaving the skin on doesn’t significantly change the protein content, but it does add fat and calories. A skin-on chicken breast has roughly the same grams of protein, but the extra fat from the skin bumps up total calories by 50 to 100 per breast. If your goal is to maximize protein per calorie, skinless is the better choice. If you’re less concerned about calories and enjoy the flavor, the skin won’t hurt your protein intake.
Why Chicken Protein Is Effective for Muscle
Chicken is a complete protein, meaning it contains all nine essential amino acids your body can’t produce on its own. This matters because incomplete proteins, like those found in soy, pea, or wheat, are low or lacking in one or more of these amino acids and are less effective at triggering muscle repair and growth.
Chicken protein also appears to outperform even other animal proteins in some respects. A study comparing chicken protein to beef protein in healthy adults found that chicken delivered significantly higher blood levels of essential amino acids and leucine (the amino acid most responsible for triggering muscle repair) from 30 minutes to 3 hours after eating. The researchers concluded that chicken protein may stimulate muscle building and enhance recovery more effectively than beef protein. For anyone eating chicken after a workout, that’s a meaningful edge.
How Chicken Compares to Other Proteins
Chicken breast sits near the top of common protein sources on a per-gram basis. Lean beef (such as sirloin) comes in around 26 to 29 grams of protein per 100 grams cooked, roughly comparable to chicken thigh but below chicken breast. Salmon provides about 20 to 25 grams per 100 grams, with the added benefit of omega-3 fatty acids. Firm tofu lands around 8 to 10 grams per 100 grams, so you’d need to eat three to four times as much tofu to match a chicken breast.
Where chicken really stands out is its protein-to-calorie ratio. A skinless breast delivers its 31 grams of protein in only about 165 calories per 100 grams. Beef tends to carry more fat (and therefore more calories) for a similar protein yield, and tofu provides far less protein per calorie even though tofu itself is low calorie.
Cooking Method Matters
The protein content of chicken stays relatively stable regardless of how you cook it. Grilling, baking, poaching, and air frying all preserve the protein. What changes is the calorie count. Pan-frying in oil or butter can add 50 to 150 calories depending on how much fat you use. Breading and deep-frying adds both calories and carbohydrates while diluting the protein concentration, since the breading takes up weight without contributing much protein.
One thing to keep in mind: cooking reduces the water content of chicken, which is why raw and cooked values differ. A 200-gram raw breast might weigh around 170 grams after cooking, but the protein itself doesn’t disappear. It just becomes more concentrated per gram of finished meat. When tracking protein, always note whether you’re weighing raw or cooked, since the difference can throw off your numbers by 15 to 25%.
