A boneless, skinless chicken thigh has about 170 calories per 3-ounce cooked serving. That number shifts depending on whether the skin is on, the bone is in, and how you cook it. Here’s what you need to know to count accurately.
Calories by Serving Size
USDA data for a roasted, boneless, skinless chicken thigh puts a standard 3-ounce (84g) serving at roughly 170 calories, with 9 grams of fat and 20 grams of protein. But most chicken thighs you buy at the store are larger than 3 ounces. A single cooked boneless, skinless thigh typically weighs around 116 grams (about 4 ounces), which brings the calorie count closer to 230 calories per thigh.
If you’re weighing portions at home, a quick rule: boneless, skinless chicken thigh runs about 200 calories per 100 grams cooked. That makes the math easy whether you’re eating one thigh or splitting a pack across meal-prep containers.
How Skin and Bone Change the Count
Leaving the skin on adds a meaningful amount of fat and calories. Chicken skin is mostly rendered fat after cooking, and a skin-on thigh can run 50 to 70 additional calories compared to its skinless counterpart, depending on size. For a single skin-on, bone-in thigh, expect roughly 280 to 300 calories total.
Bone-in thighs are trickier to estimate because the bone itself adds weight but zero calories. About 21% of a bone-in chicken thigh’s total weight is bone. So if you buy a 6-ounce bone-in thigh, only about 4.7 ounces of that is actually meat and skin. Weigh after removing the bone, or subtract roughly one-fifth of the total weight before calculating calories.
Chicken Thigh vs. Chicken Breast
The calorie gap between thighs and breasts comes down to fat. A 3-ounce boneless, skinless breast has about 140 calories and 3 grams of fat. The same serving of thigh has 170 calories and 9 grams of fat, triple the fat for about 30 extra calories. Protein is comparable in both cuts, hovering around 20 grams per serving.
That extra fat is why thighs stay juicier during cooking, especially at higher temperatures or longer cook times. If you’re strictly counting calories, breast meat is leaner. But the difference per serving is modest enough that choosing thighs for flavor and texture is a reasonable trade-off for most people.
What Cooking Method Does to Calories
A roasted or grilled chicken thigh keeps its calorie count close to the baseline numbers above, since you’re not adding much (if any) cooking fat. Pan-frying in oil adds roughly 30 to 50 calories per thigh depending on how much oil is absorbed. Deep-frying pushes that even higher, especially with breading, which soaks up oil and can nearly double the calorie count of a plain thigh.
Baking, air-frying, and grilling are the most calorie-neutral methods. If you’re pan-searing, measuring your oil (one teaspoon is about 40 calories) gives you a more accurate total than eyeballing it.
Nutritional Benefits Beyond Calories
Chicken thighs are dark meat, and dark meat carries more of certain vitamins and minerals than white meat. Per 3.5-ounce serving, dark meat contains nearly three times as much zinc as breast meat (2.8 mg vs. 1 mg) and about 28% more iron (1.33 mg vs. 1.04 mg). It also delivers more riboflavin and pantothenic acid, both B vitamins involved in energy metabolism.
A single thigh is also a strong source of selenium, providing about 29% of the daily value, and niacin, covering about 24%. These aren’t nutrients most people think about when picking a protein source, but they add up over time if chicken thighs are a regular part of your meals.
Quick Calorie Reference
- Boneless, skinless thigh (1 thigh, ~116g cooked): approximately 230 calories
- Boneless, skinless thigh (3 oz / 84g cooked): approximately 170 calories
- Bone-in, skin-on thigh (1 thigh, cooked): approximately 280 to 300 calories
- Boneless, skinless breast (3 oz / 84g cooked): approximately 140 calories
These numbers assume roasted or baked preparation with no added fat. Adjust upward for any oil, butter, marinades, or breading used during cooking.
