The Case for Leaving Salmon Skin On
Cooking salmon with the skin on is the preferred method for many home cooks and professional chefs, and for good reason. The skin serves as a natural protective barrier, shielding the delicate fillet from direct heat and helping the fish cook more evenly. This is especially crucial for high-heat cooking methods like pan-searing and grilling, where the skin prevents the flesh from sticking to the pan or grates and falling apart.
One of the most prized results of cooking with the skin on is achieving a perfectly crispy, browned exterior. For this to happen, the fish must be patted dry thoroughly before cooking and placed skin-side down in a hot, oiled pan. The skin renders its fat, creating a delicious, crunchy texture that provides a fantastic contrast to the moist, flaky meat. For those concerned about the fat, much of it can be rendered out during the cooking process. Furthermore, salmon skin contains a high concentration of nutrients, including a significant amount of the healthy fats and protein that make salmon such a popular health food.
Achieving the Perfect Crispy Skin
- Start skin-side down: Always begin cooking the fillet skin-side down in a hot, oiled pan. This allows the skin to become golden and crisp before the flesh overcooks.
- Apply pressure: For the first 10-15 seconds, use a spatula to gently press down on the fillet. This ensures the entire skin surface makes contact with the pan and prevents the fillet from curling up.
- Pat it dry: Moisture is the enemy of crispy skin. Use paper towels to pat the fillet completely dry before seasoning.
- Be patient: Cook the fillet mostly on the skin side. Don't flip it until you see the opaque color of the cooked fish climb about three-quarters of the way up the side of the fillet. At this point, the skin will easily release from the pan.
When Removing the Skin is the Right Choice
While crispy salmon skin is a delicacy for many, it's not always desirable. Some cooking methods or recipes benefit from having the skin removed entirely. For instance, when poaching salmon, the skin becomes soft, rubbery, and unappealing. Similarly, if you are slow-roasting the fish, the skin will not crisp up and will retain an undesirable gummy texture. Removing the skin is also necessary when a recipe calls for the salmon to be chopped, such as for salmon burgers, cakes, or salads. If you plan to serve the salmon with a sauce that is meant to coat both sides of the fillet, a skinless fillet is best.
For those who simply do not enjoy the taste or texture of salmon skin, removing it after cooking is a surprisingly easy option. For baked salmon, for example, the skin creates a protective layer, and when cooked, the fillet will easily slide off the skin with the help of a spatula.
How to Remove Salmon Skin
- Before cooking (raw): Place the salmon fillet skin-side down on a cutting board. Use a sharp, flexible knife held at a slight downward angle, beginning at the tail end. Hold the tail firmly and work the knife with a sawing motion, pushing forward between the skin and the flesh while pulling the skin taut.
- After cooking (cooked): If you cooked the salmon skin-side down, the skin should be easily removable. Simply slide a fish spatula between the skin and the cooked flesh to separate them, leaving the skin behind in the pan.
Skin-On vs. Skin-Off: A Comparison
| Feature | Skin-On | Skin-Off |
|---|---|---|
| Best for... | Pan-searing, grilling, broiling. | Poaching, slow-roasting, chopping for cakes, serving with sauce. |
| Protection | Acts as a barrier against direct heat, helping prevent sticking and overcooking. | No protection; risk of sticking and drying out if not handled carefully. |
| Texture | Can be cooked to a wonderfully crispy, crunchy texture. | Always tender and uniform in texture; avoids a chewy or rubbery result. |
| Flavor | Adds a rich, savory depth from the rendered fat. | Offers a clean, simple flavor, allowing the seasonings on both sides to shine. |
| Nutritional Value | Retains more of the healthy omega-3 fats and proteins contained in and under the skin. | Minimal difference in nutritional value for the flesh, but loses the skin's concentrated nutrients. |
| Preparation | Requires less prep work, but skin must be patted dry. | Requires more effort to remove the skin before cooking. |
Conclusion: The Final Verdict
The choice is yours, but it should be a deliberate one. The best rule of thumb is to match your cooking method with the presence or absence of the skin. If your goal is a beautifully pan-seared or grilled salmon with a delightfully crunchy top layer, leave the skin on. It protects the fish, adds a textural element, and retains valuable nutrients. If you're poaching, slow-roasting, or using the salmon for a mixed dish, removing the skin is the right move for a superior final texture. The best culinary experiences come from knowing your ingredients and techniques, and this decision is a key part of mastering delicious salmon.
