A cooked 3-ounce salmon fillet usually packs about 22 to 24 grams of protein, with larger fillets climbing well past 30 grams.
Salmon earns its place on dinner plates for one plain reason: it gives you a lot of protein without forcing you to eat a huge portion. If you’re tracking macros, comparing fish to chicken, or just trying to build a meal that sticks with you, salmon is one of the easier picks.
The catch is that “a salmon fillet” can mean a small frozen piece, a thick restaurant cut, or a big center-cut portion from the seafood counter. Protein changes with size, species, and whether the fish is raw or cooked. Once you know the usual range, the numbers get much easier to judge at a glance.
Why Salmon Protein Numbers Bounce Around
Protein in salmon is tied to edible weight. A thicker fillet has more protein because there’s simply more fish on the plate. Cooking also changes the number per ounce since water cooks off, which makes the protein look more packed in.
Species matter too. Atlantic salmon, sockeye, coho, pink, and chum are all salmon, yet they don’t land on the same fat and calorie profile. Their protein numbers stay in a close band, though, so the gap is usually smaller than people expect.
The simplest way to think about it is this: cooked salmon often lands near 7 to 8 grams of protein per ounce. Raw salmon is a bit lower per ounce since it still holds more water.
How Much Protein Is In a Salmon Fillet On Your Plate?
If you want a fast answer for meal planning, use this rule of thumb: a standard cooked fillet serving gives you a little over 20 grams of protein, and a hearty fillet can push beyond 30 grams without much effort.
That makes salmon handy for lunch and dinner. You don’t need a giant slab to build a high-protein meal. Add rice, potatoes, beans, or a grain bowl, and the whole plate starts doing some real work.
- 3 ounces cooked: about 22 to 24 grams of protein
- 4 ounces cooked: about 29 to 32 grams
- 5 ounces cooked: about 36 to 40 grams
- 6 ounces cooked: about 43 to 48 grams
Those ranges won’t match every fillet down to the gram, but they’re close enough for daily eating. If you weigh your portion after cooking, your estimate will land tighter than eyeballing it raw.
Protein In A Salmon Fillet By Size And Style
Portion size is the main driver, so it helps to match the fillet in front of you with a rough protein total. This is where most label confusion disappears. A “single fillet” on a package can be tiny, while a restaurant “fillet” can be almost double that.
Use this table as a practical cheat sheet for common servings.
| Salmon Portion | Cooked Weight | Protein Range |
|---|---|---|
| Small fillet | 3 oz | 22–24 g |
| Standard grocery fillet | 4 oz | 29–32 g |
| Large dinner fillet | 5 oz | 36–40 g |
| Restaurant portion | 6 oz | 43–48 g |
| Half fillet in a salad or bowl | 2 oz | 14–16 g |
| Cooked salmon flakes for pasta | 1 oz | 7–8 g |
| Large center-cut piece | 7 oz | 50–56 g |
| Meal-prep tray portion | 4.5 oz | 32–36 g |
Those numbers line up with official seafood nutrition charts. The FDA’s cooked seafood nutrition chart lists about 24 grams of protein in a 3-ounce serving of Atlantic, coho, sockeye, or chinook salmon, with chum and pink salmon a touch lower at about 22 grams.
That’s why one salmon dinner can look modest and still leave you full. Protein adds up fast once the fillet moves past 4 ounces.
Raw vs cooked fillet numbers
This trips people up all the time. A raw fillet loses water in the pan, oven, or air fryer, so the cooked piece weighs less even though the total protein in that piece didn’t vanish.
Say you start with a 5-ounce raw fillet. After cooking, it may weigh closer to 4 ounces. If you compare the raw label to the cooked plate without that shrinkage in mind, the math can look off when it actually isn’t.
Skin-on vs skinless fillets
The skin doesn’t move the protein count much. Most of the protein sits in the flesh, so the bigger swing still comes from total edible fish. If you eat the skin, you’re getting more fat and a bit more overall intake, though not a giant jump in protein.
How Salmon Stacks Up Against Your Daily Protein Goal
Food labels in the United States use a Daily Value of 50 grams for protein on a 2,000-calorie diet. The FDA Daily Value page lays out that benchmark, which gives you a quick way to frame a salmon meal.
A 3-ounce cooked salmon serving gets you close to half that mark. A 6-ounce fillet can get you near the full Daily Value in one sitting. That doesn’t mean everyone needs the same amount each day, though it does show why salmon feels like a high-protein food in real life, not just on paper.
| Cooked Salmon Portion | Protein | Share Of 50 g Daily Value |
|---|---|---|
| 3 oz | 22–24 g | 44%–48% |
| 4 oz | 29–32 g | 58%–64% |
| 5 oz | 36–40 g | 72%–80% |
| 6 oz | 43–48 g | 86%–96% |
If you split protein across the day, salmon makes that job easy. Pair a modest fillet with eggs at breakfast or Greek yogurt later on, and you won’t need much extra effort to hit a solid total.
What Changes The Count At The Store Or In A Restaurant
Labels can be tricky because some packages show nutrition for raw weight, while prepared seafood charts often show cooked values. Frozen vacuum-packed portions also differ from fresh counter cuts. The fish itself may be similar, but the listed serving size can throw you off.
Restaurants add another wrinkle. Menus rarely tell you cooked ounces unless the place leans macro-friendly. A “salmon entrée” often lands in the 5- to 7-ounce range before sides, so the protein can be way higher than people guess.
- Check whether the listed serving is raw or cooked.
- Look at ounces, not just “1 fillet.”
- Expect restaurant salmon to be bigger than a home meal-prep portion.
- Glazes and sauces add calories, not much protein.
If you’re buying fish for weekly meals, there’s another layer beyond protein. The FDA and EPA’s fish advice page helps sort seafood choices by type and frequency, which is handy if salmon is becoming a regular staple in your rotation.
Wild vs farmed salmon
Protein stays close between the two. The bigger split tends to show up in fat and calories, not in a dramatic protein swing. If your main question is muscle-building or meal satisfaction, portion size matters more than the wild-or-farmed label.
Canned salmon vs fresh fillet
Canned salmon is still protein-rich, though the texture and serving style are different. It’s a handy swap for salads, patties, sandwiches, and rice bowls when you don’t feel like cooking a full fillet.
Easy Ways To Estimate Protein Without A Food Scale
Not everyone wants to weigh fish at dinner. That’s fine. You can still get close enough for meal planning.
A cooked salmon fillet about the size of your palm usually falls near 3 to 4 ounces. A larger piece that covers most of the plate often lands near 5 to 6 ounces. Once you know that, you can peg most portions into a rough protein bracket in seconds.
- Palm-size cooked piece: think 22 to 32 grams of protein.
- Large steakhouse-style cut: think 40 grams or more.
- Flaked salmon in a bowl: count 7 to 8 grams per cooked ounce.
That’s close enough for nearly anyone who isn’t measuring every gram. If you do track tightly, weigh the cooked portion once or twice and you’ll train your eye fast.
What To Take From The Numbers
Salmon is one of the easier proteins to budget into a meal because the range is steady. A modest cooked fillet lands around the low 20s in grams of protein, and larger cuts can carry a meal almost by themselves.
If you’re staring at a piece of salmon and trying to guess the payoff, a simple rule works well: count on about 7 to 8 grams of protein per cooked ounce. That one shortcut gets you close most of the time, whether the fish is baked, pan-seared, grilled, or air-fried.
