Cooked Chicken Breast Nutrition: Calories, Protein & Macros

Choose Your Cooked Chicken Reference

Before using the table or calculator, choose the preparation that most closely matches your chicken:

If you know the method, use it. That is more precise than using a generic cooked number for everything.

Cooked Chicken Breast Nutrition at a Glance

Plain cooked boneless, skinless chicken breast commonly provides around:

• 30 to 32 g protein per 100 g
• approximately 150 to 166 calories per 100 g, depending on the cooking reference
• little carbohydrate (0 g)
• relatively little fat when skin and added fats are excluded

For example, Healthline currently reports approximately 165 to 166 calories and 31 to 32 g protein per 100 g cooked chicken breast, while Verywell Fit's grilled 85 g reference scales differently. That doesn't mean one number must be wrong. The values can describe different preparations or source records. Use the specific cooking method and source shown beside our calculator rather than applying one number to every cooked chicken breast.

Calculate Nutrition for Your Cooked Chicken

Chicken breasts do not come in standard sizes, which is why I prefer using your actual food-scale measurement. If your chicken is already cooked and sitting on the scale, enter the weight you actually measured (for example, 200 grams) and choose your cooking method.

Cooked Chicken Breast Nutrition Facts per 100g

Plain cooked, boneless, skinless chicken breast is a protein-dense food. Common cooked references provide approximately 30 to 32 grams of protein per 100 grams, little to no carbohydrate and relatively little fat when no skin or substantial cooking fat is included.

However, I don't recommend memorizing one calorie number and applying it to every cooked chicken breast. A grilled piece and a boiled piece can have different moisture levels. A chicken breast brushed with oil can be nutritionally different from one cooked without added fat. The table on this page therefore always identifies the cooking method, skin status, serving weight, added-fat status, and source record before showing the numbers.

What Stands Out Nutritionally?

Plain cooked, skinless chicken breast is a concentrated source of protein because cooking removes water from the meat. It contains little to no carbohydrate unless ingredients such as breading, sugary sauces or marinades are added. The biggest mistake is assuming the nutrition from plain cooked breast also applies to fried chicken, breaded chicken, heavily marinated chicken, restaurant chicken, or skin-on chicken. Those foods should use their own nutrition references.

Cooked Chicken Breast Calories and Protein by Weight

Serving-size values are calculated from the selected cooked reference (Grilled) and rounded for practical use. This replaces separate indexable 4 oz, 6 oz, 8 oz and 200 g cooked-chicken pages.

How to Log Cooked Chicken Correctly

If you cooked your chicken first and weighed it afterward, this is the method I recommend:

Why Does Cooked Chicken Have More Protein per 100g?

This can look strange at first. You may see approximately 22 to 23 g protein per 100 g raw, but 30 to 32 g protein per 100 g cooked. It may look like cooking created protein. It didn't.

The main explanation is water loss. A raw chicken breast contains a substantial amount of water. During cooking, some of that water evaporates or leaves the meat. The finished chicken becomes lighter. So 100 g cooked chicken usually represents more original raw chicken than 100 g raw chicken. That makes protein and calories more concentrated when both foods are compared by equal weight.

How Much Weight Does Chicken Lose When Cooked?

There is no single conversion that works perfectly for every chicken breast. Cooking loss depends on:

• preparation method
• thickness
• cooking temperature
• time
• final internal temperature
• starting moisture
• brining
• injected solution
• resting

A chicken breast that is cooked gently may retain more moisture than one cooked longer or at a higher temperature. This is why we should not state that chicken always loses exactly 25% of its weight. Any conversion tool should be labeled estimated raw-to-cooked weight unless the visitor measured their own batch.

Does Cooking Chicken Increase Its Calories?

Cooking plain chicken does not magically add energy. If you begin with chicken and use no calorie-containing ingredients, the biggest reason calories appear higher per 100 g after cooking is water loss.

But cooking can increase the calories of the finished dish when you add ingredients such as:

• oil
• butter
• breading
• cheese
• sauce
• sugar

There is an important difference between calories becoming more concentrated per 100 g and adding new calories through ingredients. For example, plain grilled chicken and breaded fried chicken should never use the same nutrition entry. They are different prepared foods.

Should You Weigh Chicken Raw or Cooked?

You can do either. The important part is matching the nutrition entry to the state in which you weighed it.

If your food scale measurement is raw, use raw chicken data. If your measurement is cooked, use cooked chicken data.

This rule is simple, but it prevents a surprising amount of confusion. The problem usually comes from switching states, for example, weighing 150 g cooked chicken but logging 150 g raw chicken. That does not describe the same original amount of meat.

How to Track a Cooked Chicken Portion

Let's say you cook several chicken breasts for the week. At lunch, you place one portion on your food scale and it weighs: 170 grams cooked.

Choose the cooked preparation that best matches the batch. If you grilled it, use a grilled reference. If you baked it, use the baked or roasted reference that matches your methodology. Then calculate the nutrition for 170 grams.

Do not enter 170 grams into a raw chicken entry. The raw and cooked weights do not represent the same original amount of meat.

What If You Batch Cook Chicken?

Batch cooking gives you another accurate option, particularly useful if you meal prep:

I like this method because it uses your actual cooking loss instead of assuming that every chicken breast loses a fixed percentage. It is very useful when several chicken breasts were cooked together, pieces have different sizes, or cooking loss is uneven.

Important batch tip: If several ingredients were cooked together (for example: chicken + olive oil + honey + soy sauce), calculate the recipe rather than treating the final food as plain chicken.

Does the Cooking Method Change the Nutrition?

Yes, especially when you're comparing values per 100 grams. There are two different effects: water loss (which changes nutrient concentration) and added ingredients (oil, butter, broth, marinades, breading, sauces).

Does Cooking Oil Count?

Yes. Plain cooked chicken references generally describe the chicken itself unless the food record specifically says otherwise. If you add oil during cooking and some remains on or in the finished food, it contributes calories and fat.

One mistake I would avoid is telling readers that all the oil you put in the pan was absorbed. That isn't necessarily true. Some oil may remain in the pan, drip away, stay on equipment, or remain on the food. For accurate recipe tracking, measure ingredients and calculate the whole finished recipe whenever possible.

What About Marinades and Sauces?

It depends on what is in them. A simple lemon-and-herb marinade may contribute very little energy. A marinade containing olive oil, honey, sugar, syrup, or mayonnaise can make a meaningful difference.

Sauces can also substantially increase sodium (such as soy sauce, brines, commercial marinades, and seasoning blends). Plain cooked chicken values should not be treated as complete meal values when these ingredients are used. If those ingredients are part of your meal, track them as part of the recipe instead of relying only on plain chicken values.

Does the Skin Matter?

Yes. Chicken skin contains additional fat and calories.

This page defaults to cooked, boneless, skinless chicken breast because that is the central reference food. If the skin was eaten, choose a skin-on reference instead. Do not simply add a universal calorie number for "the skin" unless it comes from a matching source record.

What If the Chicken Came Pre-Cooked?

Check the label. Pre-cooked products such as refrigerated grilled chicken strips, frozen cooked chicken, rotisserie chicken, deli chicken, and canned chicken can contain added sodium, broth, seasonings, sugar, starch, oils, or preservatives.

For a specific commercial food, the current product Nutrition Facts label is usually more relevant than a generic USDA chicken reference. A useful rule is:

• Generic chicken: use a generic food reference.
• Specific product: use the product's own label.

What About Cooked Chicken From a Restaurant?

If a restaurant publishes nutrition for the exact item you ate, use the restaurant's official information. Do not try to estimate restaurant chicken using plain chicken breast alone if oil, seasoning, marinade, sauce, bun, or cheese are part of the item. Check our Restaurant Chicken Nutrition section where appropriate.

How Much Protein Is in Cooked Chicken Breast?

Common cooked skinless chicken-breast references provide roughly 31 to 32 grams of protein per 100 grams. For example, Healthline currently reports about 32 grams of protein per 100 grams cooked chicken breast, while its calorie guide uses approximately 31 grams. Verywell Fit lists 26 grams of protein in an 85-gram grilled serving.

Those differences are exactly why we identify the specific preparation and source rather than presenting one unexplained value. If your cooked reference contains 31 grams of protein per 100 grams, then 200 grams would provide approximately 62 grams of protein. That is a calculated serving value.

How Many Calories Are in 100g of Cooked Chicken Breast?

Around 165 calories per 100 grams is one of the most commonly quoted numbers for plain cooked skinless chicken breast. But it is not the only valid value. Different cooked reference foods can produce different numbers because of preparation, moisture loss, natural composition, and source record. Use the selected cooking-method record on this page rather than treating 165 as a universal constant.

How We Source Cooked Chicken Nutrition Data

Cooked chicken is more complicated than raw chicken because the preparation itself affects moisture and sometimes added ingredients. That is why our cooked chicken data is organized by cooking method rather than forcing every cooked result into a single number.

For each reference, we document the exact food, cooking method, skin status, bone status, serving basis, USDA FoodData Central record, whether added fat is represented, and date checked.

Data Labels

This keeps nutrition data transparent instead of presenting every number as though it came directly from a laboratory test of your specific chicken breast.
