For home cooks, chefs, and anyone meticulously tracking nutrition, understanding how much weight the bone adds to chicken thighs is a practical and important detail. The raw weight of a bone-in, skin-on chicken thigh can be misleading for portion control, as a significant portion is inedible bone.
The Average Bone-in Thigh Weight
Individual chicken thighs vary in size depending on the bird's age and breed. However, a typical raw, bone-in, skin-on chicken thigh generally weighs between 150 and 175 grams, which is approximately 5 to 6 ounces. The bone itself can account for a considerable fraction of this total weight. For example, if a raw thigh weighs 160 grams, the bone alone could weigh 24 to 34 grams, based on the 15-21% average.
Calculating Bone Weight in Chicken Thighs
Calculating the precise weight of the bone in a chicken thigh can vary. Sources provide figures ranging from 15% to 21% for the thigh specifically. This range accounts for differences in chicken size and butchering styles. For practical purposes, using a conservative average like 18% provides a reliable estimate for yield calculations. This means that for every 100 grams of bone-in chicken thigh, you can expect roughly 82 grams of meat, fat, and skin. For those requiring a more precise number, a kitchen scale is the most accurate tool. Weighing the thigh before cooking and then weighing the discarded bone and skin afterward will give you the exact yield for that particular piece.
Edible Yield Calculation
To determine the usable meat yield from bone-in thighs, follow these steps:
- Record initial weight: Weigh the raw, bone-in chicken thighs (As-Purchased or AP weight).
- Cook and Debone: Cook the thighs and then carefully remove all the edible meat from the bones.
- Weigh the Trim: Weigh all the inedible parts, including the bones, cartilage, and any discarded skin (Trim weight).
- Calculate Edible Weight: Subtract the trim weight from the cooked total weight to find the Edible Product (EP) weight.
- Determine Yield Percentage: Divide the EP weight by the AP weight and multiply by 100 to find the yield percentage. EP weight ÷ AP weight x 100 = Yield %
Raw vs. Cooked Yield
It's important to remember that cooking drastically affects the total weight of the chicken thigh. During the cooking process, the chicken loses water, which reduces its overall mass. A cooked thigh will weigh less than its raw counterpart, and this water loss is distinct from the weight of the bone. Therefore, when calculating nutritional information, it's crucial to use cooked weights for the edible portions to get an accurate count. For example, a 160-gram raw thigh with skin and bone might yield only 80-90 grams of cooked, edible meat, depending on the cooking method.
Factors Influencing Bone and Meat Yield
Several factors can affect the bone-to-meat ratio in chicken thighs:
- Chicken size: Larger chickens generally have a better meat-to-bone ratio than smaller ones, meaning a higher percentage of their total weight is edible meat.
- Butchering precision: The way the thigh is cut and prepared by the butcher can influence how much meat is left attached to the bone.
- Cut type: The bone-in cut might include more or less of the hip joint, altering the overall bone weight.
Bone-in vs. Boneless Thighs: A Comparison
For most home cooks, the choice between bone-in and boneless thighs often comes down to a balance of cost, flavor, and convenience. Here is a comparison of the key differences:
| Feature | Bone-in, Skin-on Thighs | Boneless, Skinless Thighs |
|---|---|---|
| Cost | Generally more economical per pound. | More expensive per pound due to processing. |
| Flavor | Bone and skin add extra flavor and moisture to the meat during cooking. | Less flavor from the bone, but still richer than breast meat. |
| Cooking Time | Requires longer cooking times to ensure thorough cooking near the bone. | Cooks much faster and more evenly. |
| Preparation | Requires deboning for some recipes, though cooking on the bone is often simpler. | Ready to use for recipes like stir-fries or curries. |
| Yield | Lower yield of edible meat by weight (approx. 79-85%). | 100% edible yield, simplifying portion and cost calculations. |
Using Those Chicken Bones
If you choose to purchase bone-in thighs and debone them yourself for a recipe, don't throw away the bones! They are a valuable byproduct that can be used to add flavor to other dishes. Consider these uses:
- Homemade Stock: Create a rich, flavorful chicken stock or broth by simmering the bones with vegetables like onions, carrots, and celery.
- Soup Base: Use the stock as a base for soups, gravies, and sauces.
- Roasted Flavor: Roasting the bones before making stock will give it a deeper, more savory flavor.
Conclusion
In summary, the bone adds an average of 15-21% to the total weight of a raw chicken thigh. This variance is influenced by factors like the size of the chicken and the specific cut. While less convenient for some recipes, bone-in thighs can be more cost-effective and provide a richer flavor profile due to the bone and skin. For precise nutritional tracking or cost analysis, it is best to calculate the actual edible meat yield after cooking. For those who choose to debone themselves, the leftover bones offer an excellent opportunity to create delicious homemade stock, turning a potential waste product into a valuable ingredient.

For those who need absolute precision
For those who need the most accurate measurements, the best method is to use a kitchen scale. This allows you to measure the 'as purchased' weight of the bone-in thigh and then the 'trim' weight of the bone after cooking. This empirical method removes all guesswork and provides the most reliable data for your specific ingredients and cooking process.
A note on convenience and cost
For many, the added cost of boneless chicken thighs is a worthwhile trade for the convenience. However, for those seeking to maximize flavor and minimize food costs, buying bone-in and deboning at home is a simple task with added culinary benefits. The decision ultimately rests on your cooking goals and priorities.
