This is where the question becomes a little more complicated.
Fish can contain environmental contaminants, and some pollutants can accumulate in fatty tissues. Because salmon skin contains fat, people sometimes worry that eating the skin could expose them to more contaminants.
The actual risk depends on several factors, including:
- The type of salmon
- Where it was caught or raised
- Local environmental conditions
- How frequently you eat it
- Applicable food-safety recommendations
For commercially sold salmon, buying fish from reputable sources and following local fish-consumption advisories are sensible precautions.
If you're eating recreationally caught salmon, check the fishing area's current consumption guidance before deciding how much to eat, particularly if local authorities have issued specific advice about contaminants.
Is Wild Salmon Skin Better Than Farmed Salmon Skin?
Neither category is automatically unsafe.
Wild and farmed salmon can both be safe choices when properly sourced and handled. Their nutritional profiles can differ, and contaminant levels can vary depending on the specific fish and its environment.
Rather than assuming one type is always better, pay attention to the source and any applicable food-safety advisories.
Should You Wash Salmon Skin?
You don't need to scrub salmon skin aggressively.
Instead, handle raw salmon safely and avoid splashing contaminated water around your kitchen. If the fish has loose scales or debris, you can gently remove them or ask the fishmonger to prepare the fillet for you.
More important than washing the fish is preventing cross-contamination.
Use clean cutting boards and utensils, wash your hands after handling raw seafood, and keep raw fish separate from ready-to-eat foods.
How to Make Salmon Skin Crispy
If you're going to eat the skin, cooking it properly makes a huge difference.
1. Pat the Skin Dry
Use paper towels to thoroughly dry the salmon skin.
This is one of the most important steps for achieving crisp skin. Excess moisture creates steam and makes browning more difficult.
2. Season the Salmon
Season both sides according to your recipe.
A simple combination of salt, pepper, garlic, and lemon works beautifully.
3. Start Skin-Side Down
Heat a skillet over medium to medium-high heat and add a small amount of cooking oil.
Place the salmon skin-side down.
Press gently with a spatula for the first minute or so if the fillet begins to curl.
4. Let the Skin Cook Undisturbed
Resist the temptation to constantly move the fish.
Allowing the skin to remain against the hot pan gives it time to brown and crisp.
5. Finish Cooking the Fish
Once the skin is crisp and golden, flip the salmon and finish cooking the other side.
Cook until the fish reaches the appropriate internal temperature for your preferred level of doneness and applicable food-safety guidance.
For a straightforward food-safety target, the FDA recommends cooking finfish to 145°F (63°C).
What If the Skin Isn't Crispy?
There's nothing wrong with eating salmon skin when it's cooked but soft. However, many people find the texture much more enjoyable when crisp.
If your skin stays rubbery, common causes include:
- The skin wasn't dried thoroughly
- The pan wasn't sufficiently heated
- Too much oil was used
- The fish was moved around too often
- The pan was overcrowded
Dry skin and steady heat are your best friends.
Can You Eat Salmon Skin From Baked Salmon?
Yes.
Salmon skin can be eaten whether the fish is baked, grilled, pan-seared, or cooked using another method, provided the fish is properly handled and cooked.
Baking won't necessarily make the skin as crisp as pan-searing, though.
If crispy skin is your goal, pan-searing is usually the easiest approach.
What About Salmon Skin From Sushi?
This is a different situation.
Raw or undercooked fish carries a greater food-safety risk than properly cooked salmon. Salmon intended for raw consumption must meet appropriate handling and sourcing requirements, but labels such as "sushi-grade" aren't a universal guarantee of safety.
If you're preparing salmon at home, cooking it thoroughly is the simplest way to reduce the risk associated with foodborne pathogens.
Should You Remove the Skin Before Cooking?
You don't have to.
Leaving the skin attached can actually help protect the flesh while the salmon cooks, particularly when pan-searing.
It can also make the fillet easier to handle.
If you don't enjoy the texture, however, you can simply remove the skin after cooking. It often separates from the flesh more easily once the salmon has been cooked.
Who Should Be More Careful With Fish?
Certain people are advised to pay particular attention to fish choices and consumption amounts, including pregnant people, young children, and others who may have specific dietary or health considerations.
For these groups, following current guidance from public-health authorities about fish species, serving frequency, and local advisories is especially important.
If you have a medical or dietary reason to limit seafood or contaminants, your healthcare professional can provide advice appropriate to your situation.
Frequently Asked Questions
Is salmon skin healthy?
Salmon skin provides protein and contains fat, including omega-3 fatty acids. Its nutritional value varies depending on the salmon and preparation method.
Is it okay to eat salmon skin every time?
For most people, salmon can be part of a healthy diet. However, overall fish consumption should be varied and based on current dietary and local fish-advisory guidance.
Does cooking salmon remove contaminants?
Cooking can kill many harmful microorganisms, but it does not reliably eliminate environmental contaminants such as mercury or certain persistent pollutants. That's why choosing fish wisely remains important.
Should I remove salmon skin because of mercury?
Not automatically. Mercury levels depend largely on the species and size of the fish rather than simply whether you eat the skin. Follow relevant fish-consumption advisories.
How do I make salmon skin crispy?
Dry the skin thoroughly, use a properly heated skillet, place the salmon skin-side down, and avoid moving it around until the skin has browned and crisped.
The Bottom Line
Yes, salmon skin is generally safe to eat when the fish is properly sourced, handled, and cooked.
It can add delicious flavor and texture to a meal, and it contains some of the beneficial fats associated with salmon.
If you're cooking a fresh fillet, there's usually no need to remove the skin simply because you're concerned about safety. Instead, focus on proper food handling, thorough cooking, reputable sourcing, and following any local fish-consumption advisories.
And if you can get that skin beautifully crisp in a hot skillet, don't be surprised if it becomes your favorite part of the salmon.
