Salmon Anatomy and Cuts Guide: A Chef’s Complete Guide to Salmon Cuts
There is something special about working with a whole salmon in a professional kitchen. The moment you place that beautiful fish on the cutting board, you can already imagine the dishes it can become: a crisp-skinned fillet, a rich belly portion, a grilled collar, a beautiful steak cut, or even a flavorful stock made from the bones and head.
Understanding salmon anatomy and cuts is not only useful for professional chefs. It also helps home cooks buy better fish, cut portions correctly, reduce waste, and choose the right cooking method for each part. The image above gives us a practical look at the major sections of a salmon, from the head and collar to the whole fillet, belly, tail, bones, and steak cut.
In this guide, I’ll walk you through the salmon cuts every chef and home cook should know, explain where each cut comes from, how it behaves during cooking, and how I would use it in a real kitchen.
Understanding Salmon Anatomy Before You Cut
Before picking up your knife, take a moment to understand the shape of the fish. A salmon is not one uniform piece of meat. Different areas have different thickness, fat levels, textures, and connective structures.
The image identifies several important parts, including the head, cheeks, collar, top loin, shoulder, back, belly, tail, fins, rib bones, pin bones, whole fillet, and steak cut.
Knowing these sections makes cutting much easier because you begin to understand why your knife should travel in certain directions.
When filleting a whole salmon, the basic goal is to follow the backbone and rib cage closely. This produces clean fillets while leaving as much usable meat on the bones as possible. Professional filleting guides recommend keeping the blade close to the backbone and using a sharp, flexible knife for better control.
The Head: More Than Kitchen Waste
Many home cooks remove the salmon head and immediately throw it away. In my kitchen, I would never do that unless there was a specific reason.
The head contains flavorful meat around the cheeks and collar, while the bones can contribute excellent flavor to fish stock.
If you are making a seafood broth, soup, sauce base, or stock, the head can be extremely useful. Just make sure the fish is fresh and properly cleaned before using it.
The head is also part of learning to cook sustainably. A skilled cook looks at the entire fish and asks, “How much of this can I use?”
✓ Use the head for fish stock or broth.
✓ Remove the cheeks for a small but flavorful portion.
✓ Trim usable meat carefully rather than leaving it attached to the bones.
Salmon Cheeks: A Small Chef’s Treasure
The cheeks are small portions located around the head. They are easy to overlook, but they can be wonderfully tender and rich.
Because the cheeks are small, they work beautifully as an appetizer or special bite. You can pan-sear them quickly with butter, garlic, herbs, and lemon.
The important thing is not to overcook them. They do not need aggressive cooking. A hot pan, a little oil, and careful timing are usually enough.
For beginner cooks, salmon cheeks are also a good way to practice portion control because every piece is naturally small.
The Collar: One of the Most Flavorful Cuts
The salmon collar sits just behind the head around the shoulder and gill area. It contains flavorful meat and fat, which is why chefs often treat it as a valuable cut rather than a scrap.
The James Beard Foundation specifically highlights the collar and belly as some of the tastiest parts of a fish and recommends using them to improve overall yield.
I like the collar grilled, roasted, or broiled until the outside becomes beautifully browned. It can also be fried for a crisp finish.
There is one important point: the collar contains bones, so it should be handled carefully. If serving it to guests, check the portion thoroughly before plating.
✓ Grill the collar for smoky flavor.
✓ Roast it with lemon, garlic, and herbs.
✓ Fry it when you want crisp edges and rich flavor.
✓ Use the bones and trimmings for stock when appropriate.
Shoulder and Top Loin
Moving toward the main body of the salmon, you will find the shoulder and top loin areas. These sections are generally thicker and excellent for portioning.
The top loin is one of the most attractive parts of the fillet for a clean restaurant-style presentation. Its thickness makes it easier to cook evenly without drying the fish too quickly.
When I portion salmon for service, I look for pieces with relatively even thickness. Even portions cook more predictably, which is especially important when several plates need to leave the kitchen together.
A common beginner mistake is cutting portions at random widths. One piece may be very thick while another is thin. The result is uneven cooking.
Use your knife deliberately and aim for consistent portions.
The Back: A Great Area for Main Fillets
The back section produces substantial meat and is closely connected with what we commonly think of as the main salmon fillet.
This is a versatile cut. You can roast it whole, portion it into individual servings, pan-sear it, grill it, or use it for other preparations.
When cooking a thick piece, remember that heat continues moving through the fish after it leaves the pan or oven. This is why a chef watches both temperature and carryover cooking rather than simply leaving salmon over heat until it looks completely dry.
For food safety, the FDA and USDA recommend cooking fish to an internal temperature of 145°F (63°C), measured with a food thermometer.
The Belly: Rich, Fatty, and Full of Flavor
The belly is one of my favorite salmon cuts because it has a higher fat content and a softer, richer texture than many other sections.
You can see the belly clearly in the image as the long, thinner strip along the lower portion of the fish.
Because it is relatively thin and rich, the belly cooks quickly. This makes it excellent for grilling, roasting, pan-searing, or cutting into smaller pieces.
The main mistake here is overcooking. Thin belly portions can go from juicy to dry surprisingly quickly.
Keep the heat under control and watch the fish closely.
Belly Strip
The belly strip is a narrower portion taken from the belly area. It can be used in smaller servings, appetizers, sushi-style preparations where appropriate and safely handled, or cooked as a rich side portion.
For a simple home preparation, season the strip with salt and pepper and roast or pan-sear it until just cooked through.
The belly also works well when you want a stronger salmon flavor in a dish because its richness brings plenty of character without requiring a complicated sauce.
Pin Bones: The Little Bones You Must Check
One of the most important finishing steps when preparing a salmon fillet is removing the pin bones.
These are small bones running through the central portion of the fillet. They can be difficult to see, which is why I always use my fingers rather than relying only on my eyes.
Run clean fingertips gently along the flesh. If you feel a sharp point, use fish tweezers or clean needle-nose pliers to remove it.
Pull the bones in the direction they are naturally positioned rather than aggressively pulling sideways. This helps reduce damage to the flesh.
Professional filleting instructions also recommend feeling along the fillet and removing remaining pin bones with tweezers or small pliers.
✓ Run your fingers over the entire fillet.
✓ Use fish tweezers for better control.
✓ Remove bones before portioning when possible.
✓ Check every portion again before serving.
Rib Bones and the Belly Bones
The rib bones are attached near the belly side of the fillet. They are different from the smaller pin bones and require a slightly different approach.
Lay the fillet skin-side down and carefully slide a sharp knife underneath the rib bones. Keep the blade shallow. Your goal is to remove the bones while sacrificing as little meat as possible.
This is where a sharp knife makes a major difference. A dull knife forces you to push harder, which can tear the salmon and create unnecessary waste.
One good principle in the kitchen is simple: let the knife do the work.
Whole Salmon Fillet
The whole fillet shown in the image is one of the most useful salmon cuts for home cooks and professional kitchens.
Instead of cutting it into individual portions immediately, you can cook the whole side as one large presentation piece.
A whole roasted salmon fillet works particularly well for family meals, buffet service, and dinner parties. It also gives you control over how you portion the fish after cooking.
When buying a whole fillet, look for firm flesh, clean appearance, and a fresh smell. Strong sour, rancid, ammonia-like, or unpleasant fishy odors are warning signs that the seafood should not be eaten.
Center-Cut Fillet
The center-cut fillet is one of the easiest cuts to cook evenly because it has a substantial, fairly uniform shape.
This is often the cut I would recommend to a beginner who wants restaurant-quality results without working with a whole fish.
It is excellent for pan-searing, roasting, grilling, or baking.
The trick is to avoid constantly moving the salmon around in the pan. Let the surface develop color before turning it. A good sear creates texture while the interior stays moist.
Tail Fillet and Tail Section
The tail portion becomes progressively thinner. That means it cooks faster than the thicker center section.
This is where beginners often make a mistake: they cook the tail portion for exactly the same time as a thick center-cut piece.
Instead, think about thickness rather than just weight.
A thin tail piece may need less cooking time. If you are cooking several different cuts together, place thicker pieces in the hotter or earlier part of the cooking process and monitor the thinner ones carefully.
The tail is also useful for smaller portions, fish cakes, salads, pasta dishes, and other preparations where perfect uniformity is less important.
Salmon Steak Cut
The image also shows the classic salmon steak cut. Instead of cutting the fish lengthwise into a fillet, the fish is sliced crosswise into thick sections.
A salmon steak usually contains a central bone structure and has skin around the outside.
It has a traditional, attractive appearance and works particularly well on a grill, in a roasting pan, or under a broiler.
The main challenge is the bone. Always warn diners or check the portion carefully before serving.
For a home cook, steak cuts can be especially convenient because they hold their shape well during cooking.
How to Fillet a Whole Salmon Step by Step
If you are starting with a whole salmon, take your time. Speed comes later with practice.
First, make sure the fish is properly scaled, gutted, and clean. Pat it dry so your hands and knife have better control.
Position the salmon securely on a large cutting board.
✓ Use a sharp filleting knife.
✓ Make the first cut behind the gill and collar area.
✓ Follow the backbone toward the tail using long, controlled strokes.
✓ Lift the fillet gently as you work instead of forcing the knife.
✓ Repeat on the opposite side.
✓ Remove the rib bones with shallow cuts.
✓ Feel for and remove pin bones.
✓ Skin the fillet if your recipe requires skinless salmon.
✓ Trim uneven edges only after you have removed the major bones.
Professional guides emphasize keeping the knife close to the backbone and rib cage to maximize usable meat and reduce waste.
Common Salmon Cutting Mistakes
Even experienced cooks can waste fish when rushing. The biggest problems usually come from poor knife control rather than complicated technique.
✓ Using a dull knife: A dull blade tears delicate flesh instead of making clean cuts.
✓ Cutting too deeply: Follow the bones rather than cutting straight through the fish.
✓ Removing too much belly meat: The belly is valuable and flavorful.
✓ Ignoring pin bones: Always check the fillet with your fingers.
✓ Making uneven portions: Consistent thickness helps every piece cook at a similar rate.
✓ Handling the fish roughly: Salmon flesh bruises and tears easily.
✓ Overcooking thin sections: Tail and belly portions need closer attention than thick center cuts.
Chef’s Tips for Better Salmon Cuts
Here are a few habits I recommend to culinary students and home cooks.
Keep your workstation cold and clean. Salmon is delicate, so avoid leaving it unnecessarily at room temperature.
Dry the fish before cutting or searing. Excess surface moisture can make it harder to achieve good browning.
Keep your knife clean between major cutting stages. A clean blade gives you better control and keeps the fish looking professional.
Do not throw away every trimming. Small pieces can be used in fish cakes, chowders, sauces, stocks, or other preparations depending on their condition.
And remember that presentation begins with the cut. A beautifully cooked salmon portion will always look better when the cut is clean and intentional.
Best Cooking Methods for Different Salmon Cuts
Different cuts deserve different treatment.
✓ Center-cut and top loin: Excellent for pan-searing, roasting, grilling, and baking.
✓ Belly: Best for quick cooking methods such as grilling, broiling, or pan-searing.
✓ Collar: Excellent grilled, roasted, or fried.
✓ Cheeks: Quick pan-searing works beautifully.
✓ Tail: Ideal for smaller portions, salads, pasta, cakes, and quick cooking.
✓ Whole fillet: Great for roasting and large-format presentation.
✓ Steak cut: Excellent grilled, roasted, or broiled.
The secret is matching the cut to the cooking method. Thin pieces need speed and attention, while thick pieces benefit from gentler, controlled cooking.
Serving and Presentation Ideas
When plating salmon, keep the presentation simple. Salmon already has a beautiful natural color, so you do not need to cover it with too much sauce.
For a restaurant-style plate, place the salmon slightly off-center and add a small amount of sauce underneath or beside it. Finish with fresh herbs, lemon, seasonal vegetables, or a light salad.
For a family-style meal, serve a whole roasted fillet on a large platter with lemon wedges, herbs, roasted vegetables, and a simple sauce.
The goal is to let the salmon remain the star of the plate.
Final Chef’s Takeaway
Learning salmon anatomy and cuts changes the way you look at the whole fish. Instead of seeing one large ingredient, you begin to see many useful cuts, each with its own texture, fat level, cooking time, and purpose.
From the cheeks and collar to the belly, center-cut fillet, tail, whole fillet, and steak cut, every section can have a place in the kitchen.
Most importantly, good salmon preparation is about control. Use a sharp knife, follow the natural structure of the fish, remove bones carefully, portion evenly, and choose the cooking method according to the cut.
Once you understand the anatomy, you will waste less, cook more confidently, and get much more value from every salmon you bring into your kitchen.
