One 100-gram cooked serving of black cod has around 18–20 grams of protein plus rich omega-3 fats in a tender, filling piece of fish.
Black cod, also called sablefish, is known for its rich texture and buttery taste, but many people are just as curious about its protein. If you eat fish for muscle repair, appetite control, or general nutrition, the numbers in each portion matter. This guide walks through how much protein sits in black cod, how that compares with other protein sources, and how to use it in everyday meals without overdoing calories or mercury.
Why Protein In Black Cod Matters
Protein gives your body the building blocks it needs for muscles, enzymes, and many day-to-day processes. Fish is a popular way to get that protein because it comes with almost no carbohydrate and, in many cases, helpful fats. Black cod falls into the “fatty fish” camp, so every serving brings both protein and omega-3s to the plate.
Health agencies such as the American Heart Association describe fish as a solid protein choice that comes with less saturated fat than many cuts of red meat and an added dose of omega-3 fatty acids like EPA and DHA, which link to heart health when eaten as part of a balanced pattern of meals. At the same time, U.S. guidance from the EPA and FDA encourages adults and children to eat a variety of fish while watching mercury levels and overall intake.
Within that picture, Black Cod Protein helps you reach daily protein targets without giving up flavor. The fish is rich, so portion size matters, but the protein content is right in line with what many people look for at lunch or dinner. Once you understand the grams per 100 grams and per fillet, it becomes easier to build meals that match your calorie and macro goals.
Black Cod Protein Per 100 Grams And Per Fillet
Most nutrition databases group black cod under sablefish. Data based on USDA FoodData Central shows that 100 grams of raw sablefish deliver roughly 17 grams of protein and about 250 calories. Cooked portions of black cod sit in a similar range, with many sources putting protein at around 18–20 grams per 100 grams of cooked fish, depending on moisture loss and cooking style.
| Preparation | Protein (g Per 100 g) | Calories (kcal Per 100 g) |
|---|---|---|
| Raw Sablefish (Black Cod) | ~17 | ~250 |
| Baked Or Broiled, Plain | ~18 | ~250 |
| Pan-Seared With Light Oil | ~18–19 | ~270–290 |
| Grilled Fillet | ~18–20 | ~250–270 |
| Miso-Glazed Restaurant Style | ~18–20 | ~300–350 |
| Smoked Black Cod | ~20 | ~280–320 |
| Skin-On Portions, Cooked | ~18–20 | ~260–300 |
These ranges are based on lab data for sablefish and typical cooking methods. Oil, marinades, and sauces will raise calories more than they change protein. The fish itself stays fairly steady, because protein sits in the flesh, not the added fat around it.
Portion Sizes You Actually See On The Plate
Home cooks and restaurants rarely serve exactly 100 grams of fish. A small fillet of black cod often lands at 120–140 grams, while a hearty portion can reach 170–180 grams. At 18–20 grams of protein per 100 grams cooked, that means:
- 120 g cooked black cod: roughly 22–24 g protein
- 150 g cooked black cod: roughly 27–30 g protein
- 180 g cooked black cod: roughly 32–36 g protein
Those numbers put one fillet right in the range many people target for a main source of protein at a single meal. If you like to split protein across the day, one modest piece of black cod at dinner plus eggs, dairy, tofu, or beans earlier covers a large slice of most daily targets.
Protein In Black Cod For Everyday Meals
Daily protein needs vary with age, activity level, and body size, but many nutrition experts now steer active adults toward at least 1.2–1.6 grams of protein per kilogram of body weight each day. For a 70-kilogram person, that lands around 84–112 grams of protein from all sources. Black Cod Protein can cover around a quarter of that range in one 150-gram serving, leaving plenty of room for other foods.
A simple way to think about it: picture your plate in thirds. One third is black cod, one third is fiber-rich vegetables, and one third is a carb source such as potatoes, rice, or whole grains. Add a small starter or snack with dairy, tofu, or legumes and you now have a day that hits solid protein numbers without relying on giant portions of fish or meat.
How Black Cod Protein Compares With Other Foods
It helps to see black cod alongside other popular protein sources. Cooked Atlantic salmon brings about 22 grams of protein per 100 grams, while cooked Atlantic cod can reach 22–23 grams in the same weight of fish. Skinless, roasted chicken breast sits higher, at roughly 30–32 grams of protein per 100 grams. Firm or regular tofu, depending on style, often gives around 17 grams of protein per 100 grams.
That puts black cod slightly below salmon, cod, and chicken breast for pure protein density, yet above many plant options on a gram-for-gram basis. The trade-off is fat: black cod and salmon come with far more total fat and calories than lean cod or chicken breast. For someone aiming to keep calories low while pushing protein as high as possible, very lean fish or poultry may suit that target better.
On the other hand, if you want a moderate protein dose plus omega-3 fats in a smaller, richer piece of fish, black cod fits nicely. You can pair a modest portion with a big pile of vegetables and a light carb side and still reach balanced macros for the meal.
Balancing Protein, Fat, And Calories In Black Cod
Black cod is one of the richest finfish in terms of fat content. That fat sits around 20 grams per 100 grams of cooked fish, with calories near 250 per 100 grams. The protein-to-calorie ratio is lower than in lean cod or chicken breast, yet the meal feels satisfying because fat slows digestion and adds flavor.
The main trick is portion control and menu planning. If you serve a 120-gram piece of black cod alongside roasted vegetables and a light starch, the full meal stays in a comfortable calorie range for most people while still landing more than 20 grams of protein. If you choose a larger 180-gram fillet with rich sides, the same dinner can move into restaurant-level calorie territory very quickly.
Cooking Methods And Their Effect On Protein
Cooking changes texture and moisture more than it changes protein grams. When black cod cooks, water leaves the flesh, so a 100-gram cooked portion started out heavier when raw. The total protein in the piece stays almost the same; the number per 100 grams of cooked fish rises slightly because there is less water left.
Gentle Cooking
Baking, broiling, or steaming black cod on moderate heat keeps shrinkage low and protects delicate flesh. These methods keep fat addition under control, especially when you use a light brush of oil rather than a heavy pour. Protein content per fillet stays in the same range, while calories reflect any added oil or glaze.
Pan-Searing And Grilling
Pan-searing and grilling create crisp edges and a deeper flavor. A teaspoon or two of oil in the pan adds about 40–80 extra calories to the dish. Protein, though, hardly shifts. If you are tracking macros, you can safely assume that a seared black cod fillet still aligns with the 18–20 grams of protein per 100 grams cooked, then adjust calories upward to account for the oil and any sweet sauces.
Sample Day Of Meals With Black Cod
Once you know the protein numbers, black cod becomes easy to plug into a day of eating. Here is a simple, high-protein layout that includes one portion of black cod at dinner along with familiar foods at other meals.
| Meal | Dish | Approx Protein (g) |
|---|---|---|
| Breakfast | Two Eggs Scrambled With Spinach | ~14 |
| Morning Snack | Greek Yogurt (150 g) With Berries | ~12–15 |
| Lunch | Quinoa Salad With Chickpeas And Veggies | ~15–18 |
| Afternoon Snack | Handful Of Nuts (30 g) | ~5–6 |
| Dinner | 150 g Baked Black Cod With Roasted Vegetables | ~27–30 |
| Evening Bite | Small Glass Of Milk Or Soy Beverage | ~7–9 |
| Daily Total | Mixed Sources Including Black Cod | ~80–90 |
This style of day suits someone with moderate energy needs who wants a stable flow of protein across meals. You can shift portion sizes up or down, swap in tofu or beans for one of the animal sources, or move the fish portion to lunch instead of dinner. The key move is to treat black cod as a rich anchor for one meal, not the only source of protein all day.
Safety, Mercury, And How Often To Eat Black Cod
Protein is only part of the picture when you plan fish intake. The U.S. EPA and FDA publish joint guidance that sorts fish into “best choices,” “good choices,” and “choices to avoid” for people who may become pregnant, are pregnant, are breastfeeding, or are feeding young children. Black cod typically lands in the middle list, meaning it can fit into the weekly pattern yet should not be the only fish you eat week after week.
For most adults, those agencies suggest about two to three servings of a variety of fish per week. That leaves room for black cod once in a while, plus leaner, lower-fat choices on other days. If you have specific medical conditions or take medication that affects how your body handles fat or mercury, talk with a healthcare professional about how often to include rich fish such as black cod.
Getting Reliable Numbers For Black Cod Protein
Nutrition labels on packaged black cod and values in apps or cookbooks all trace back in some way to lab data. For sablefish, the lab reference often comes from the USDA FoodData Central database, which tests raw and cooked samples and lists protein, fat, vitamin, and mineral content. When you see 17–20 grams of protein per 100 grams of black cod in different places, they are usually rounding the same source data or adjusting for typical cooking loss.
Because real fillets vary in thickness and fat content, it makes sense to treat any single number as a close estimate rather than a perfect measurement. If you weigh your cooked portion and use values from the USDA FoodData Central entry for sablefish along with the EPA-FDA advice about eating fish and shellfish, you will land in a realistic range for both protein and safe intake.
Final Thoughts On Black Cod Protein Intake
Black cod brings together a moderate dose of protein, a generous amount of fat, and a strikingly soft texture. That mix makes it a strong pick for people who want seafood dinners that feel special, yet still help meet daily protein goals. A single 120–150 gram serving can cover roughly a quarter to a third of many adults’ daily protein needs.
If you enjoy the flavor and plan portions with care, black cod fits well into a weekly rotation alongside leaner fish, poultry, eggs, and plant protein. Use the protein ranges in this guide as a practical map, weigh your fillets when you can, and pair black cod with plenty of vegetables and modest starch portions. You get a meal that tastes rich, lands within a sensible calorie range, and keeps your protein intake on track.
