A 100-gram cooked serving of black cod (sablefish) delivers about 17–20 grams of high-quality protein along with rich omega-3 fats.
Black cod has a rich, silky texture that makes it a favourite on restaurant menus and in home kitchens. Behind that indulgent bite sits a steady dose of protein, and knowing the exact black cod protein content helps you track macros, plan portions, and compare it with leaner fish such as salmon or cod.
In nutrition databases, black cod appears under the name sablefish. Standard entries for cooked sablefish per 100 grams cluster around 17–20 grams of protein, with roughly 250 calories thanks to its higher fat content. Those numbers shift with cooking method and portion size, so it makes sense to know how they play out on a real plate rather than only on a lab printout.
If you log food for sports, weight management, or general health, knowing your black cod protein content by weight and cooking method lets you record meals with far more confidence than guessing from a similar fish.
Why Black Cod Protein Content Matters For Your Plate
Protein gives structure to muscle, skin, and connective tissue, and it also keeps meals satisfying. Black cod brings a mix of protein and fat instead of the very lean profile you see in many white fish. That balance changes how full you feel, how many calories you eat, and how the fish fits with the rest of your day’s food.
Because black cod is fatty, each bite carries more calories than the same weight of cod or haddock. The protein count per 100 grams stays respectable, though, so a modest fillet still helps you reach daily protein targets. That makes portion planning more nuanced: you get solid protein, but you do not need huge servings to feel full.
The quality of the protein also matters. Like other fish, black cod delivers all the essential amino acids in amounts that match human needs, which places it in the “complete protein” group. Combine that with long-chain omega-3 fats and you get a fish that can hold its own in a week’s meal plan, even if you also lean on leaner cuts of meat or plant protein.
Black Cod Protein Content By Serving Size
Food databases such as the USDA FoodData Central sablefish entry list cooked black cod at about 17 grams of protein per 100 grams of fish. Using that baseline, you can map common serving sizes to realistic protein totals.
| Serving Description | Cooked Portion (g) | Protein (g) |
|---|---|---|
| Small Taste Or Side Portion | 50 | 9 |
| Light Meal Portion | 75 | 13 |
| Standard 100 g Serving | 100 | 17 |
| Typical Home Fillet | 120 | 20 |
| Restaurant-Style Fillet | 140 | 24 |
| Large High-Protein Portion | 180 | 31 |
| Very Generous Sharing Plate | 200 | 34 |
These values use simple rounding from the 17 g per 100 g cooked figure. If your fillet looks closer to 150 g once cooked, you can place it between the 140 g and 180 g rows and expect around the high-20s in grams of protein.
Estimating Protein From Raw Fillet Weight
Labels on frozen black cod often list raw weight, but you eat the cooked weight. Black cod loses water and some fat in the pan or oven, so a 170 g raw fillet might land closer to 140 g once cooked. If you only know the raw weight, one tidy approach is to:
- Multiply raw weight by about 0.8 to guess cooked weight.
- Use the table to pick the closest cooked amount.
- Read off the matching protein estimate.
That method keeps your macro log tighter than a blind guess, especially when you repeat similar recipes week after week.
Black Cod Protein Levels Per 100 Grams
When people compare fish, they usually ask about protein per 100 grams. For cooked black cod, most lab entries sit between 17 and 20 grams of protein per 100 grams of edible portion. Raw black cod per 100 grams often shows slightly lower protein numbers because the raw fillet contains more water.
Raw Versus Cooked Black Cod
Cooking drives off water and some fat, which concentrates nutrients. If a raw entry lists 15–17 g of protein per 100 g, the cooked entry based on the same fish can climb to the upper end of that range. That is why you should always check whether a database entry says “raw” or “cooked, dry heat” before you log the protein.
For day-to-day tracking, it usually helps to pick one reference style and stick to it. Many people choose cooked weights and cooked nutrition data because that matches what lands on the plate.
Skin, Glaze, And Bones
Black cod fillets may come skin-on or skinless, with or without a thin layer of ice glaze. The protein sits in the muscle, not in the glaze, so if you weigh a frozen portion without trimming the ice you slightly overestimate the true grams of fish and protein. Skin adds some fat and a small amount of protein, but the effect per serving is modest.
If a recipe includes bones or a thick miso crust, remember that the table above reflects boneless, unbreaded cooked fish. Any extra coating adds calories and may dilute the protein per 100 grams of the finished dish, even if the total protein from the fish itself stays the same.
How Black Cod Protein Fits Into Your Day
Most adults do well with protein spread through the day instead of crammed into one meal. Public resources such as the Proteins section on Nutrition.gov describe protein needs in the context of body weight, age, and activity. Many general guidelines land near 0.8 grams of protein per kilogram of body weight as a baseline, with higher ranges for people who train hard or are in energy deficits.
From that angle, a moderate black cod portion can cover a big share of one meal’s protein target. A 140 g cooked fillet with about 24 g of protein gives a solid chunk of the day’s intake without forcing you into a huge plate of food. Pair that fish with beans, lentils, tofu, eggs, or dairy and you reach robust totals without relying on supplements.
Using Black Cod In High Protein Meals
If you aim for a high protein breakfast, lunch, or dinner, think about black cod as a centrepiece with supporting sides that also carry protein. A meal could include 140 g of black cod, a cup of quinoa or lentils, and a yoghurt-based sauce. The fish sets a base of 20–25 g of protein, and the sides lift the plate into the 35–40 g range that many lifters use per main meal.
For lighter days, you might cut the fillet portion to 100 g and lean more on vegetables and starchy sides, trading some protein for fewer calories while keeping omega-3 intake attractive.
Balancing Fat And Protein
Black cod is known for fat content that rivals salmon and even passes it in some datasets. That fat lands mostly in the unsaturated category, including EPA and DHA. From a macro perspective, this means black cod delivers less protein per calorie than very lean fish or chicken breast, yet it still beats many red meats in terms of fat quality.
For people who like rich fish and do not want to give up that texture, black cod becomes a neat way to blend comfort with macro-aware eating. You just adjust portion size and side dishes to keep the overall balance in line with your goals.
Black Cod Protein Compared With Other Foods
It helps to see how black cod stacks up against other common protein sources. The figures below use cooked values from datasets that draw on USDA FoodData Central and similar lab analyses.
| Food | Protein (g) Per 100 g | Calories Per 100 g |
|---|---|---|
| Black Cod (Sablefish), Cooked | 17 | 250 |
| Salmon, Cooked | 22 | 206 |
| Atlantic Cod, Cooked | 23 | 105 |
| Chicken Breast, Cooked | 33 | 187 |
This comparison shows why chefs call black cod a “buttery” fish. Per 100 g, it carries less protein and more calories than lean cod or chicken breast. Salmon sits in the middle: more protein than black cod, fewer calories per 100 g, but still a fatty fish.
That does not make black cod a poor protein source. It simply means that if you treat it as your main protein at a meal, you manage serving size and pair it with leaner sides. If you already get plenty of protein from dairy, eggs, meat, or plant sources earlier in the day, black cod can slide into an evening slot that emphasises flavour and omega-3 fats while still pushing your protein total in the right direction.
Where Black Cod Shines
Because black cod is rich and forgiving during cooking, you are less likely to dry it out than very lean fish. That makes it handy for people who are new to cooking fish at home yet still want meals that align with macro targets. You can roast, grill, or pan-sear it and still land close to the protein counts in the tables above, as long as you weigh the cooked fish and avoid heavy breading.
How To Read Black Cod Protein Labels And Data
Packaged black cod may display nutrition facts per 100 g, per fillet, or per serving that does not match the portion you actually eat. On top of that, some labels use raw values while others use cooked values. To keep your log tight, match three things every time you read a label: food state, portion size, and data source.
Check Whether The Data Is Raw Or Cooked
The label or database line should say “raw,” “baked,” “broiled,” or “cooked, dry heat.” If that tag is missing, many branded packages still use raw data for legal reasons. In that case, you can either:
- Log raw weight and raw protein per 100 g, or
- Switch to a cooked entry in a trusted database and weigh your fish after cooking.
For home tracking, the second route usually feels closer to what you actually eat, especially when you trim skin or dark edges after cooking.
Match The Portion On Your Plate
If a label lists 20 g of protein “per serving” and defines that serving as 85 g of cooked fish, but you eat a 140 g fillet, you can scale the numbers. Multiply the listed protein by your portion weight divided by the label’s serving weight. In this example, 20 g × (140 ÷ 85) lands near 33 g of protein.
Databases often provide ready-made sliders for this kind of scaling. Even so, weighing your cooked fish once or twice helps you see how your usual fillet size compares with the nominal serving on the package.
Choosing Reliable Sources For Black Cod Protein Content
For the most dependable black cod protein content figures, stick to data grounded in lab analysis. USDA FoodData Central underpins many nutrition tools, including third-party sites that present sablefish entries with user-friendly charts. Nutrition portals backed by public agencies, such as Nutrition.gov, also give context on total daily protein needs and the place of seafood within a balanced pattern.
When you combine those references with a kitchen scale and a few simple rules of thumb, you can turn a luxurious black cod dinner into clear numbers in your food log. You get the pleasure of the dish and the clarity of knowing how much protein you just added to your day.
