Branzino Protein Content | Lean Protein From Sea Bass

A 3.5-ounce cooked branzino portion provides roughly 20–24 grams of protein, giving you a lean seafood choice for high-protein meals.

Branzino, also known as European sea bass, turns up on menus as a whole roasted fish with crisp skin and tender, mild flesh. If you track macros or care about how much protein lands on your plate, the first question is simple: how much protein do you actually get from that fillet or whole fish?

Most nutrition datasets place branzino in the same protein range as other lean white fish. A cooked 100-gram portion supplies around 20–24 grams of protein with very little fat or carbohydrate, which makes it easy to fit into many eating styles, from low-carb to Mediterranean-style plates.

This guide breaks down protein in branzino by serving size, compares it with other popular seafood, and shows simple ways to use it through the week without turning every meal into a math exercise.

Branzino Protein Content By Common Serving Size

Different sources list slightly different numbers for protein in branzino because they use different cuts, cooking methods, and measurement points. Some list values for raw fillets, others for cooked portions, and some for a single fillet size. When you look at the range as a whole, a clear pattern shows up.

Data from nutrition analysis sites and compiled nutrient tables generally place branzino between about 18 and 24 grams of protein per 100 grams, depending on whether the fish is raw or cooked, the exact cut, and how much moisture cooks off. One dataset gives 18.43 grams of protein per 100 grams, while another reports 23.8 grams of protein in a 101-gram cooked fillet, which works out to a very similar ratio.

Protein Per 100 Grams Raw And Cooked

Raw branzino fillet usually sits slightly lower in protein per 100 grams than cooked branzino because raw fish holds more water. Once the fillet hits a hot pan or oven, some moisture leaves, and the same amount of protein squeezes into a slightly smaller package. That means cooked branzino tends to land on the higher end of the protein range per 100 grams.

For everyday use, many home cooks and nutrition coaches round the numbers to simple ranges. A practical rule of thumb is:

• Raw branzino fillet: around 18–20 grams of protein per 100 grams.
• Cooked branzino fillet: around 20–24 grams of protein per 100 grams.

These ranges line up with values reported in detailed branzino nutrition breakdowns and neighbor the numbers you see for other lean white fish such as cod or haddock.

Protein In Typical Branzino Portions

Numbers per 100 grams help with comparisons, but the real question at the table is how much protein you get from a portion you might actually eat. Branzino is often served as a whole fish in the 350–500 gram range before cooking, which yields a smaller cooked, edible portion after you remove skin, head, bones, and fins. At home, many people work with 4–6 ounce fillets, similar to other fish recipes.

Using the ranges above, you can estimate protein output for common serving sizes. The table below keeps things simple by rounding to tidy whole numbers and ranges. Treat it as a planning tool rather than a lab report.

Serving Size	Approximate Protein (g)	Notes
100 g raw fillet	18–20 g	Higher moisture, slightly lower protein density
100 g cooked fillet	20–24 g	Protein becomes more concentrated after cooking
3 oz (85 g) cooked portion	17–20 g	Roughly a deck-of-cards size piece
4 oz (113 g) cooked portion	22–27 g	Common single serving at home
5 oz (142 g) cooked portion	28–34 g	Heavier serving for higher protein targets
One cooked fillet (~101 g)	≈24 g	Matches a typical branzino fillet nutrition entry
Whole small fish (≈250 g cooked edible)	50–60 g	After bones and head are removed
Branzino tacos (≈60 g fish)	12–14 g	Two small tacos with modest fish filling
Branzino salad topping (≈75 g)	15–18 g	Cubed or flaked over greens or grains

This table lets you match branzino servings to rough protein targets without weighing every bite. If you keep your portions near the 4–6 ounce cooked range, you can count on a solid hit of high-quality protein from each plate.

How Branzino Protein Fits Into Daily Needs

Most adults do well with a daily protein intake that at least meets the minimum set by many nutrition guidelines, often described as 0.8 grams per kilogram of body weight per day. Athletes, very active people, and those trying to preserve muscle during weight loss often aim higher, though specific numbers vary by source and personal goals.

Using a simple example, a person weighing 70 kilograms would meet that baseline with around 56 grams of protein per day. A single 5-ounce cooked branzino portion can cover roughly half of that target on its own. Two moderate portions spread through the day make it easy to reach or pass that baseline without turning to very large steaks or heavy dairy servings.

Protein Quality In Branzino

Branzino provides all the amino acids the body needs from food, which places it in the same category as other animal proteins such as eggs, chicken, and dairy. The protein is also relatively easy to digest for most people who tolerate fish, and the low fat content keeps energy per bite modest compared with richer fish.

A detailed nutrient breakdown of cooked branzino shows not only strong protein density but also helpful levels of micronutrients such as selenium, magnesium, and B vitamins, along with marine omega-3 fats. These added nutrients do not change the protein count, yet they make branzino a flexible main ingredient for balanced meals.

Protein, Calories, And Satiety

Because branzino delivers a high ratio of protein to calories, it can leave you feeling pleasantly full without loading your plate with extra energy. A 101-gram cooked fillet sits near 125 calories while still giving around 24 grams of protein, based on one widely cited dataset. That ratio compares well with many cuts of poultry and beats a lot of higher-fat meats.

When you pair branzino with fiber-rich sides such as roasted vegetables, bean salads, or whole grains, you stack protein with slow-digesting carbs and volume from plants. The mix can help keep hunger steady across the afternoon or evening, which matters when you try to stick to a set energy intake over time.

How Branzino Protein Compares With Other Seafood

Branzino sits in the same general protein band as many familiar fish. Fatty fish like salmon tend to match or slightly exceed branzino on protein per 100 grams while carrying more fat and omega-3s. Very lean white fish such as cod or pollock land just a bit lower or similar in protein while staying very low in fat.

To give some context, the table below compares approximate macronutrients for cooked fish and shellfish. Values are rounded and combine information from nutrient databases and branzino-specific breakdowns. Exact numbers vary by cut, species, and cooking method, so treat these as ranges, not exact lab values.

Seafood (Cooked)	Protein (g) Per 100 g	Fat (g) Per 100 g
Branzino (European sea bass)	20–24 g	2–3 g
Atlantic salmon	22–25 g	8–13 g
Cod	18–20 g	<1 g
Tilapia	20–21 g	2–3 g
Shrimp	20–24 g	1–2 g
Canned light tuna	24–26 g	1–2 g

This comparison shows that branzino holds its own against classic high-protein seafood choices. It gives you protein numbers that match shrimp or tuna, with a subtle flavor many people find easy to pair with herbs, citrus, and simple sides.

Beyond protein, multiple health organizations encourage regular fish intake because of the marine omega-3 fats found in many species. The American Heart Association encourages two servings of fish per week, especially fatty fish, as part of heart-conscious eating patterns. Branzino has less fat than salmon yet still contributes omega-3s and fits neatly into that guidance.

For overall fish choices, including branzino, the U.S. Food and Drug Administration publishes advice on portion frequency and mercury levels for different species, with separate charts for young children and people who are pregnant or breastfeeding. Checking the latest chart helps you balance protein goals, taste preferences, and safety guidelines when you plan seafood meals through the month.

Building Meals Around Branzino Protein

Once you know roughly how much protein sits in a fillet or whole fish, the next step is turning those numbers into easy meals. Branzino works well with simple seasoning, quick cooking, and a wide range of sides, which means you can place it into many eating patterns without much effort.

Simple High-Protein Plate Ideas

A 4–5 ounce portion of grilled branzino paired with roasted potatoes and a large salad offers a plate with around 25–30 grams of protein, slow starch, and plenty of volume from vegetables. Swap the potatoes for quinoa, farro, or brown rice if you prefer grains, and you still keep a generous share of protein at the center.

If you watch carbohydrates more closely, you can lay a branzino fillet over sautéed greens, grilled zucchini, or cauliflower mash. The protein stays steady, while calories drop and fibers from vegetables help you feel satisfied. Olive oil, lemon juice, and fresh herbs layer flavor without changing the macro picture much.

Meal Prep And Leftovers

Because branzino has a delicate texture, it reheats best with gentle methods. Many people cook extra fillets at dinner, then chill them and flake the fish into lunches the next day. A 3–4 ounce leftover portion still supplies around 18–24 grams of protein, which fits well into grain bowls, mixed salads, or whole grain wraps.

You can use pre-cooked branzino as a protein base for quick dishes such as:

• Fish tacos with cabbage, salsa, and yogurt-based sauce.
• Protein-rich salad bowls with beans, greens, and seeds.
• Warm pasta dishes where branzino replaces part of the meat or cheese.

Because the fish is mild, it takes on flavors from sauces and marinades without overpowering them, which lets you repeat branzino through the week without every meal feeling the same.

Buying, Cooking, And Safety Tips For Branzino

Freshness matters for flavor and safety. When you buy whole branzino, look for clear eyes, shiny skin, and a clean, sea-like smell. Fillets should appear moist but not soggy, with no strong fishy odor. If you buy frozen branzino, pick packages with minimal ice crystals and intact wrapping.

Food safety agencies such as the FDA and EPA share guidance on how often to eat fish and which species fit different life stages, including pregnancy and childhood. Their joint advice about eating fish and shellfish includes serving sizes, mercury ranges, and storage tips so that households can enjoy seafood while staying within recommended intakes. Branzino typically appears among options many families can enjoy in rotation alongside other low- and moderate-mercury fish.

Cooking Methods And Protein Retention

Grilling, baking, broiling, and pan-searing branzino all keep protein content virtually unchanged, because protein does not evaporate with moisture. What changes is the weight of the cooked fillet. A raw 140-gram fillet might shrink to around 115 grams after cooking, so the same amount of protein now sits in a smaller piece of fish.

If you track protein closely, weigh cooked portions rather than raw. Use the ranges from the first table, and remember that a modest change in portion size only nudges protein intake up or down by a few grams. The bigger picture comes from how often you fit branzino and other protein sources into your week.

Balancing Branzino With Other Proteins

Branzino works well alongside a mix of other proteins such as beans, lentils, eggs, yogurt, and poultry. That variety gives you different textures, flavors, and nutrient profiles while keeping daily protein totals on track. Many people aim to spread protein across meals rather than packing nearly everything into one large dinner.

When you place branzino into that mix, you get a mild, lean fish that supplies roughly 20–24 grams of protein per 100 grams cooked, very little fat, and a host of helpful micronutrients. That combination is the core of why so many menus and home cooks rely on this Mediterranean favorite when they want seafood that tastes refined yet stays simple to season and serve.
