A 3-ounce serving of roasted chicken breast has about 170 calories, making it one of the leanest protein sources available. But that number changes significantly depending on which part of the bird you eat, whether the skin is on, and how it’s cooked. Here’s a full breakdown so you can count with confidence.
Calories by Cut (3-Ounce Serving)
The USDA lists these calorie counts for a standard 3-ounce (84g) serving of roasted chicken, cooked with no added ingredients:
- Breast: 170 calories
- Drumstick: 180 calories
- Thigh: 210 calories
- Wing: 240 calories
The pattern is straightforward: white meat (breast) is leaner, while dark meat (thighs and drumsticks) carries more fat and therefore more calories. Wings are the most calorie-dense per ounce because their small size means a higher proportion of skin and fat relative to meat.
If you’re using a food scale and working in metric, 100 grams of skinless, boneless cooked chicken breast comes to 165 calories with 31 grams of protein and just 3.6 grams of fat. That protein-to-calorie ratio is hard to beat in any whole food, which is why chicken breast is a staple in meal prep and weight management plans.
How Skin Changes the Count
Leaving the skin on adds calories, though not as dramatically as you might expect. A single chicken wing with skin weighs about 34 grams and contains 86 calories. Remove the skin and that same wing drops to 43 calories (at 21 grams of edible meat). That’s roughly double the calories for the skin-on version, largely because chicken skin is high in fat: 30 grams of skin alone contains about 8 grams of unsaturated fat and 3 grams of saturated fat.
For a full chicken breast or thigh, keeping the skin on typically adds 30 to 50 calories per serving. If you’re not counting closely, this isn’t a deal-breaker. But if you’re tracking macros or trying to stay in a calorie deficit, pulling the skin off before eating is one of the simplest swaps you can make.
Cooking Method Makes a Big Difference
Roasting, grilling, and baking chicken without added oil keeps the calorie count close to baseline. Deep frying is where things change fast. A 100-gram portion of roasted chicken breast has 165 calories. The same amount of extra-crispy fried chicken breast (with skin and breading) jumps to 268 calories. That’s roughly 60% more calories, driven by the oil absorbed during frying and the flour or breading coating.
Pan-frying in a tablespoon of oil falls somewhere in between. Each tablespoon of cooking oil adds about 120 calories to the pan, though not all of it gets absorbed. A reasonable estimate is an extra 30 to 60 calories per serving when you pan-fry with oil, depending on how much the chicken soaks up.
Poaching and boiling add zero extra calories from fat, but most people find the texture less appealing than roasted or grilled. If you want to keep calories low without sacrificing flavor, grilling or roasting on a rack (which lets fat drip away) is your best bet.
Ground Chicken
Raw ground chicken runs about 143 calories per 100 grams, with a macronutrient split of roughly 49% protein and 51% fat by calorie. That fat content is higher than you’d get from a plain chicken breast because ground chicken typically includes darker meat and sometimes skin in the blend. Once cooked, the calorie count per 100 grams rises slightly as moisture cooks off and the meat becomes more concentrated.
If you’re buying ground chicken as a lower-calorie alternative to ground beef, check the label for the lean-to-fat ratio. Ground chicken labeled 93% lean will be noticeably different from an unlabeled package that includes thigh meat and skin trimmings.
Putting It Into Real Portions
A typical chicken breast from the grocery store weighs between 6 and 8 ounces raw, which shrinks to roughly 5 to 6 ounces after cooking. That means a single cooked chicken breast lands in the range of 280 to 340 calories, assuming it’s skinless and prepared without added fat. Most people eat one breast as a serving, so this is the number that matters for everyday meal planning.
A standard restaurant portion of chicken is often larger, sometimes 8 ounces cooked or more, and frequently cooked in butter or oil. A grilled chicken entrée at a restaurant can easily reach 400 to 500 calories before any sides or sauces. If you’re estimating while eating out, the USDA’s 170 calories per 3-ounce baseline is a useful anchor: just multiply based on the portion size in front of you.
For meal prep, the simplest approach is to weigh your chicken after cooking. Cooked chicken breast runs about 55 calories per ounce, cooked thigh about 70 calories per ounce. Memorize those two numbers and you can estimate nearly any chicken dish on the fly.
