What is Cold Smoked Salmon?
Cold smoked salmon is a delicacy that’s prepared by curing the fish with a mixture of salt and sugar, then slowly smoking it at low temperatures—typically under 80°F (26°C). Unlike hot smoking, cold smoking doesn’t cook the fish. Instead, it imparts a smoky flavor while maintaining the fish’s raw, silky texture. This results in a delicate, flavorful product that can be sliced thinly and used in a variety of dishes. The cold smoking process typically takes between 18 to 24 hours, depending on the thickness of the salmon and the desired flavor intensity.

Cold Smoking vs. Hot Smoking
When it comes to smoking salmon, there are two primary methods: cold smoking and hot smoking. Although both methods aim to preserve and flavor the fish, they produce very different results:
- Cold Smoking: This method involves smoking the fish at temperatures below 80°F. The fish remains raw but absorbs the smoky flavor. Cold smoked salmon is smooth, firm, and typically served thinly sliced on bagels, crackers, or salads.
- Hot Smoking: Hot smoking, on the other hand, exposes the fish to higher temperatures, usually between 180°F and 250°F. The fish is cooked during this process, resulting in a flaky texture, similar to grilled or baked salmon.
For home cooks and food enthusiasts, cold smoking offers a way to create gourmet-quality dishes. The key difference lies in texture: Cold smoked salmon retains a raw, buttery texture, whereas hot smoked salmon becomes firm and flaky.
To set up your smoker for cold smoking, you may need additional tools like a smoke tube, which ensures a steady, low-temperature smoke over long periods. You read more about smoke tube for smoking that works well for this process.
How Long to Cold Smoke Salmon?
One of the most frequently asked questions in the world of smoking is, “How long does it take to cold smoke salmon?” The time required to cold smoke salmon largely depends on the thickness of your fillet and the depth of smoky flavor you desire. As a general guideline, the process typically lasts between 18 and 24 hours.
- 18 hours: A shorter smoking period, around 18 hours, will give your salmon a mild, subtle smoky flavor. This is ideal for thinner cuts or if you prefer a lighter smoke profile.
- 24 hours: Smoking for the full 24 hours will impart a deeper, more intense smoky flavor to the fish. This is recommended for thicker fillets and for those who prefer a bold, robust taste.
The key is to monitor both the salmon and the smoker carefully. You should always keep the temperature below 80°F. Unlike hot smoking, cold smoking does not cook the salmon, and if the temperature gets too high, you risk cooking the fish and losing the signature cold-smoked texture.

Preparation: Curing the Salmon Before Smoking
Before you even think about smoking, the first step is curing the salmon. The curing process is essential for extracting moisture from the fish, which not only intensifies the flavor but also helps preserve it during the smoking process. Curing also acts as a base seasoning that balances out the smokiness and enhances the overall taste of the salmon.

Step 1: Selecting the Right Salmon
- Quality Matters: Always start with high-quality, fresh salmon. A thick fillet with good fat marbling will yield the best results, with King salmon being an excellent choice due to its rich, buttery texture. Learn more about Smoked Salmon Recipes to explore different dishes you can create.
- Removing Pin Bones: Before curing, carefully run your fingers along the flesh of the fish to locate any pin bones. Use a pair of kitchen tweezers or pliers to pull them out. This step ensures that your cold smoked salmon will be easy to slice and eat.
Step 2: Creating the Cure Mixture
The curing mixture typically consists of equal parts salt and sugar. These two ingredients work together to draw moisture out of the fish and prevent the growth of harmful bacteria during the smoking process. You can add additional seasonings like black pepper, dill, or coriander to enhance the flavor.
- Basic Cure Recipe: Combine 1 cup of kosher salt and 1 cup of brown sugar in a bowl. This ratio works for most fillets, but you can adjust it depending on the size of your salmon. Feel free to add herbs or spices for a personalized touch.
- Optional Additions: Herbs like dill, thyme, or even crushed garlic can add subtle, aromatic notes to the salmon. Additionally, coriander seeds or lemon zest can give your cold smoked salmon a unique and refreshing flavor.
Step 3: Applying the Cure
- Wrap the Fish: Lay a long piece of plastic wrap on a baking sheet. Spread a portion of your curing mixture evenly on the plastic wrap, place the salmon fillet on top, and cover it with the remaining mixture. Ensure the salmon is fully coated with the cure on both sides.
- Refrigerate the Salmon: Wrap the salmon tightly and place it in the refrigerator for 12 to 24 hours. This period allows the salt and sugar to penetrate the fish, drawing out moisture and intensifying the flavor.
Step 4: Rinsing and Drying the Salmon
After curing, rinse the fish under cold water to remove the excess salt and sugar. Pat it dry with paper towels to remove any moisture. Now, the salmon is ready for the next step: air-drying.
Step 5: Developing the Pellicle
The pellicle is a tacky layer that forms on the surface of the salmon after it has been air-dried. It plays a crucial role in the cold smoking process by helping the smoke adhere to the fish more effectively.
- Air Dry the Salmon: Place the salmon on a wire rack and leave it uncovered in the refrigerator for 4 to 8 hours. During this time, the surface of the fish will become slightly sticky. This is the pellicle forming, and it’s essential for ensuring that your fish absorbs the smoke evenly.
The Cold Smoking Process
Once your salmon has been cured and dried, it’s time to begin the cold smoking process. Cold smoking is a slow, patient method that requires precise control over temperature and smoke levels.
Step 1: Set Up Your Smoker
- Temperature Control: Cold smoking must be done at temperatures below 80°F. Use a reliable thermometer to monitor the temperature inside your smoker at all times. Cold smoking can be done using an offset smoker, a pellet grill, or even a dedicated cold smoker. The key is to avoid any heat that would cook the fish.
- Smoke Tube: A smoke tube is a valuable tool for cold smoking, as it produces consistent smoke without raising the temperature. Fill the tube with your choice of wood pellets, such as alder or maple, and place it inside the smoker. This will ensure a steady flow of smoke over several hours.
Step 2: Smoking Time
- Place the Salmon in the Smoker: Arrange the salmon fillets on the grill grates with the skin-side down. Ensure that there is enough space between each fillet for proper air circulation. You do not need to flip the salmon during the smoking process.
- Monitor the Progress: The salmon will need between 18 and 24 hours of smoking, depending on your desired flavor intensity. Check the color and texture of the fish periodically. A uniform golden-brown color and firm texture are signs that the salmon has absorbed enough smoke.
Step 3: Testing for Doneness
There are several ways to determine if your cold smoked salmon is ready:
- Texture: The fish should feel firm to the touch but not overly hard. If the salmon has a soft or spongy texture, it may need more time in the smoker.
- Color: A light, even golden-brown hue across the surface of the fish indicates that the salmon has absorbed the smoke properly.
Once your salmon has reached the desired level of smokiness, remove it from the smoker and let it cool completely before serving.
Storing and Serving Cold Smoked Salmon
Once the salmon has been smoked to perfection, it’s important to store it properly to preserve its flavor and texture. Cold smoked salmon can be used in a variety of dishes, from appetizers to main courses.
