Why make smoked salmon at home?
Smoked salmon is one of those products we associate with fine dining, hotel breakfasts, and special occasions. However, preparing it at home is more accessible than it seems. With the right ingredients, a little patience, and this guide, you can achieve a surprising result that will impress any diner.
Making homemade smoked salmon has several advantages. First, you control the quality of the source fish: you can choose wild or sustainably farmed salmon, from the origin you prefer. Second, you decide the intensity of the smoke, the salt level, and the flavorings, customizing the result to your taste. And third, the process itself is rewarding: there's something deeply satisfying about transforming a raw salmon fillet into a gourmet product with your own hands.
Of course, we must be honest: quality artisanal smoked salmon, like the kind you can find at Bacalalo, has decades of experience, professional equipment, and quality control behind it that is difficult to replicate in a home kitchen. But that doesn't mean you can't get an excellent result at home. The important thing is to understand the differences between the methods, respect food safety standards, and enjoy the process.
In this guide, we explain two complete methods: traditional cold smoking, which requires a smoker and produces a result closer to commercial smoked salmon, and cured gravlax, a Scandinavian technique that doesn't require smoke and is perfect for beginners. If you're interested in learning more about the types of smoked salmon available, we recommend our complete guide to smoked salmon.
Two methods: cold smoking vs. cured gravlax
Before you begin, it's essential to understand that there are two completely different approaches to preparing smoked salmon at home, and each produces a different result:
Cold smoking
This is the traditional method that produces smoked salmon as we know it: thin slices, silky texture, deep smoky flavor. The process involves first curing the salmon with salt and sugar, and then exposing it to wood smoke at low temperatures (between 20°C and 30°C) for several hours. The fish is not cooked but slowly smoked, which gives it its characteristic texture and unmistakable flavor.
This method requires a smoker or a homemade improvisation that allows generating smoke without excessive heat. The result is very close to the artisanal smoked salmon you would find in our smoked salmon collection, although the precision of professional equipment will always make a difference in the consistency of the final product.
Cured Gravlax (Scandinavian style)
Gravlax is a fascinating alternative that requires no smoke at all. The salmon is cured for 48-72 hours under a mixture of salt, sugar, and fresh dill, pressed with weight in the refrigerator. The result is a cured salmon with a silky, slightly translucent texture and a delicate flavor where herbs and the freshness of the fish predominate. It is milder than cold-smoked, but equally delicious.
Gravlax has the advantage of not needing special equipment: you only need a good salmon fillet, salt, sugar, dill, plastic wrap, and a weight. It's the perfect method for those who want to get started in the world of cured salmon without investing in a smoker.
Equipment needed
Depending on the method you choose, you will need different tools and materials. Here's a detailed list of what's needed for each technique:
For cold smoking
- Cold smoker: this can be a commercial smoker with a cold smoke generator, an adapted smoking box, or even a homemade system with a cardboard box and a smoke generator (sawdust tube or spiral). The essential thing is to keep the temperature below 30 °C.
- Cold smoke generator: compressed sawdust tubes and spirals are the most accessible option. They burn slowly for 4-8 hours, generating smoke without flame.
- Sawdust or wood chips: beech, oak, apple, or cherry are classic options.
- Rack or hook: to hang or support the salmon inside the smoker, allowing smoke to circulate on all sides.
- Ambient thermometer: essential to ensure the temperature does not exceed 30 °C.
- Coarse sea salt: additive- and iodine-free, preferably. Salt is the primary curing agent.
- Brown or white sugar: complements the salt in the curing mixture.
- Thin slicing knife: for slicing the final product into thin, elegant slices.
For gravlax
- Tray or dish: glass, ceramic, or stainless steel, large enough for the fillet.
- Plastic wrap: to wrap the salmon during curing.
- Weight: a cutting board with cans on top, for example. You need between 1 and 2 kg of evenly distributed weight.
- Coarse sea salt and sugar: in an approximate 2:1 ratio (salt:sugar).
- Fresh dill: in abundance, it is the star aromatic of gravlax.
- Black peppercorns: lightly crushed, adding a spicy counterpoint.

Method 1: Traditional cold smoking
This is the complete method for preparing cold-smoked salmon at home. The total process takes between 2 and 3 days, but most of the time is passive curing. The actual active work is about one hour.
Ingredients
- 1 fresh salmon fillet, 800g - 1kg, skin on, boneless
- 200g coarse sea salt
- 100g sugar (white or brown)
- 10g crushed black pepper
- A bunch of fresh dill (optional)
- Zest of 1 lemon (optional)
- Beech or oak sawdust for the smoker
Step-by-step preparation
- Check the salmon: run your fingers over the flesh to detect and remove any remaining bones. Kitchen tweezers are ideal for this. The salmon should be very fresh, with a clean sea smell, firm flesh, and uniform color.
- Prepare the curing mixture: in a large bowl, combine the salt, sugar, and crushed pepper. If using dill or lemon zest, incorporate them as well. Mix well until everything is homogeneous.
- Cure the salmon: spread a third of the mixture over a tray lined with plastic wrap. Place the salmon fillet skin-side up and cover the entire surface with the rest of the mixture, ensuring it is well covered on all sides. Wrap tightly with plastic wrap.
- Refrigerate under weight: place the wrapped salmon on a tray with a weight on top (1-2 kg). Refrigerate for 12 to 24 hours. At 12 hours, you'll have a light cure; at 24, a more intense cure. You'll see the salmon release liquid: this is normal and desirable.
- Wash and dry the salmon: rinse all the curing mixture under cold running water. Pat dry thoroughly with paper towels. Place the salmon uncovered on a rack in the refrigerator for 6-12 hours to form a sticky film on the surface called a pellicle. This layer is crucial because it allows the smoke to adhere better.
- Prepare the smoker: light the cold smoke generator and wait for it to produce a constant, fine smoke. The temperature inside the smoker should not exceed 25-28 °C. If it's hot, place a bottle of frozen water or a tray of ice inside the smoker to keep the temperature low.
- Smoke the salmon: place the salmon on the rack or hang it with a hook inside the smoker, skin-side down if horizontal. Smoke for 6-12 hours, depending on the intensity of flavor you desire. A 6-hour smoke will give a mild, elegant flavor; 10-12 hours will produce a deeper, more pronounced smoke.
- Final rest: once smoked, wrap the salmon in baking paper and let it rest in the refrigerator for at least 12 hours before slicing. This rest allows the flavors to distribute evenly throughout the piece.
- Slice thinly: with a long, sharp knife, slice at an angle into thin slices, separating the flesh from the skin. Good smoked salmon slices almost transparent, in sheets 2-3 mm thick.
Method 2: Gravlax cured with salt and dill
Gravlax (from Swedish grav, buried, and lax, salmon) is a centuries-old Scandinavian technique in which salmon is cured in salt, sugar, and dill without the need for smoke. It's the simplest and most accessible method for preparing cured salmon at home, and the result is spectacular.
Ingredients
- 1 fresh salmon fillet, 800g - 1kg, skin on, boneless
- 150g coarse sea salt
- 100g white sugar
- 2 large bunches of fresh dill
- 15g black peppercorns, lightly crushed
- Zest of 1 lemon
- 30ml vodka or aquavit (optional, enhances curing)
For the mustard and dill sauce
- 3 tablespoons Dijon mustard
- 1 tablespoon mild mustard
- 2 tablespoons sugar
- 1 tablespoon white wine vinegar
- 80 ml sunflower oil
- 3 tablespoons chopped fresh dill
Step-by-step preparation
- Mix the cure: combine salt, sugar, crushed pepper, and lemon zest in a bowl.
- Prepare the salmon: if you have a whole fillet, cut it in half to have two equal halves. Remove any bones with tweezers.
- Apply the cure: if using vodka or aquavit, first rub the flesh sides with the alcohol. Spread half of the curing mixture over the first salmon half (flesh side). Cover with a generous bunch of dill. Place the second half on top, flesh against flesh, like a sandwich. Cover the outside with the remaining mixture.
- Wrap and press: wrap the salmon sandwich tightly in several layers of plastic wrap. Place on a tray, put a weight on top (1.5-2 kg), and refrigerate.
- Flip every 12 hours: for the next 48-72 hours, flip the salmon package approximately every 12 hours. You'll see liquid accumulate: this is natural brine and is completely normal. A 48-hour cure produces a milder gravlax; 72 hours gives a firmer, more intense result.
- Clean and dry: remove the salmon from the wrap, remove the dill and excess cure. You can rinse briefly under cold water and pat dry with paper towels. The salmon should have a deeper color and the flesh should feel firm to the touch.
- Slice and serve: slice thinly at an angle, separating from the skin, just like with smoked salmon. Serve with the mustard and dill sauce, toasted rye bread, capers, and thinly sliced red onion.
To prepare the mustard and dill sauce: mix both mustards with sugar and vinegar. Gradually whisk in the sunflower oil until emulsified. Add the chopped dill, adjust salt to taste, and serve at room temperature.
Wood guide for smoking
The choice of wood is crucial for the final flavor of smoked salmon. Each type of wood adds different nuances, and knowing them will allow you to customize the result according to your preferences:
- Beech: the most widely used in Europe for smoking salmon. It produces a soft, clean, and slightly sweet smoke. It is the classic and most balanced choice, perfect for a first attempt. Most quality commercial smoked salmon is smoked with beech.
- Oak: generates a more intense and robust smoke than beech, with earthy notes and a hint of tannin. Ideal if you like a strongly flavored smoked salmon. It is frequently used in Scotland and Ireland for their premium smoked salmon.
- Applewood: produces a fruity, delicate, and slightly sweet smoke. It is excellent for those looking for smoked salmon with subtle and elegant nuances. It pairs very well with a cure that includes brown sugar.
- Cherrywood: similar to applewood but with a more aromatic touch and a slight reddish tone that contributes to the salmon's color. Medium smoke, fruity, and pleasant.
- Alder: the traditional wood of the American Pacific Northwest for smoking wild salmon. Soft, slightly sweet smoke with earthy nuances. Very balanced.
- Juniper: not used alone, but mixed with another base wood (beech or oak). Juniper berries and branches provide balsamic, resinous, and very aromatic notes. Typical in Nordic countries.
Important: never use resinous woods (pine, fir, cypress) or treated or varnished woods. They produce toxic smoke and unpleasant bitter flavors. Always use untreated, natural sawdust or wood chips specifically for food use.
Food safety and temperature control
Working with raw or semi-cured fish requires strict adherence to food safety. These are the key points you must respect without exception:
- Salmon freshness: use the freshest salmon possible, bought the same day or the day before. If you don't have access to quality salmon, consider using flash-frozen salmon at -20°C for at least 24 hours, which eliminates possible parasites like anisakids.
- Curing temperature: curing should always be done in the refrigerator, between 0°C and 4°C. Never leave salmon curing at room temperature.
- Smoking temperature: for cold smoking, the temperature should not exceed 30°C. Above this temperature, the fish begins to partially cook, which alters the texture and can create a favorable environment for bacteria if the full cooking temperature is not reached.
- Hygiene: wash your hands, utensils, and surfaces with hot water and soap before and after handling raw fish. Use cutting boards exclusively for fish.
- Salt: the salt concentration in the cure is what guarantees the safety of the final product. Do not reduce the amounts of salt indicated in the recipe: salt acts as a natural preservative by inhibiting bacterial growth.
- Consumption: homemade smoked or cured salmon should be consumed within 5-7 days refrigerated, and 4-5 days once opened. If you want to store it longer, freeze it immediately after smoking, following the tips in our smoked salmon freezing guide.
Note on anisakids: in Spain, regulations require freezing fish to be consumed raw or semi-raw at -20°C for at least 24 hours. Cold-smoked salmon and gravlax do not reach cooking temperatures, so it is advisable to pre-freeze fresh salmon before curing, especially if it does not come from aquaculture (farmed salmon has a lower risk of anisakids, but caution is always recommended).
Homemade vs. artisanal: real differences
We must be honest: homemade and professional artisanal smoked salmon are different products, although both can be excellent. Here are the main differences you should know:
- Consistency: a professional smoker controls temperature and smoke flow with pinpoint accuracy. At home, variations are greater, which can lead to uneven smoking or inconsistent curing between one preparation and another.
- Raw material: artisanal producers work with selected suppliers and receive salmon of optimal caliber, fat content, and freshness. In the retail market, quality is more variable, although excellent pieces can be obtained by buying from trusted establishments.
- Slicing: professional slicing of smoked salmon—those translucent, uniform, perfect slices—requires years of practice and a specific knife. At home, the cut will be thicker and more irregular, but this does not affect the taste.
- Time and experience: master smokers have spent decades perfecting their techniques, adjusting times, salt mixtures, and wood types. Your first homemade attempt will be an experiment; your tenth will probably be something very respectable.
If you're looking for maximum quality without effort, in our smoked salmon collection you'll find top-notch artisanal products. But if you enjoy the process and want to experiment, making smoked salmon at home is a fascinating gastronomic project.

Storage and preservation
Once your smoked salmon or gravlax is ready, proper storage is essential to maintain the quality and safety of the product:
- In the refrigerator: wrapped in baking paper (not plastic wrap, which traps moisture) and inside an airtight container or zip bag. It keeps for 5-7 days. Once you start slicing, consume within 4-5 days.
- Freezing: homemade smoked salmon freezes well. Wrap it in plastic wrap, then in aluminum foil, and place it in a freezer bag. It will keep for up to 2-3 months without losing too much quality. Always thaw in the refrigerator, never at room temperature or in the microwave.
- Portions: if you've made a large piece, consider portioning before freezing. Separate the portions with baking paper so you can take out only what you need without thawing everything.
- Vacuum packing: if you have a vacuum sealer, it's the best option for both refrigeration and freezing. It doubles the product's shelf life and better maintains its texture.

Frequently asked questions
Is homemade cold-smoked salmon safe to eat?
Yes, provided that hygiene and food safety standards are respected. Curing with salt inhibits bacterial growth, and if you also pre-freeze fresh salmon at -20°C for 24 hours, you eliminate the risk of anisakids. Always maintain the cold chain and consume the product within the indicated times.
How long does it take to make smoked salmon at home?
The complete cold smoking process requires 2-3 days: 12-24 hours of curing, 6-12 hours for pellicle formation, 6-12 hours of smoking, and 12 hours of final rest. Gravlax needs 48-72 hours of curing in the refrigerator. The active working time in both cases is less than an hour.
Can I use frozen salmon to make smoked salmon?
Yes, in fact, it is recommended. Freezing salmon at -20°C for at least 24 hours eliminates the risk of anisakids. Thaw completely in the refrigerator before starting the curing process. The texture may vary slightly compared to fresh salmon, but the final result is still very good.
What is the difference between smoked salmon and gravlax?
Smoked salmon is cured with salt and then exposed to wood smoke, while gravlax is cured only with salt, sugar, and dill, without any smoke. Smoked salmon has a deeper, more complex flavor; gravlax is fresher and more delicate, with dill and the fish itself being prominent.
Can I make smoked salmon without a smoker?
For cold smoking, you need some type of smoker, even if it's homemade. However, you can make gravlax without any special equipment. There are also very affordable portable cold smoke generators that can be used inside a large box or container as an improvised smoker.
What is the best wood for smoking salmon?
Beech is the most versatile and widely used option in Europe. It produces a clean, mild smoke. Oak gives a more intense smoke, and applewood adds fruity notes. Always avoid resinous woods like pine or fir, which produce bitter flavors and potentially toxic smoke.
How much salt do I need to cure salmon?
The standard proportion is 200g of coarse salt and 100g of sugar per kilo of salmon. This amount ensures a safe cure and a balanced flavor. Do not reduce the salt below 150g per kilo, as this would compromise the food safety of the product.
Does homemade smoked salmon taste the same as commercial?
It is similar but not identical. Homemade usually has less uniform smoking and a thicker cut, but it can be just as tasty. The main difference is consistency: a professional artisan always achieves the same result, while at home there will be variations between batches. If you are looking for the highest quality, at Bacalalo you will find top-notch smoked salmon.
What are the ingredients to make smoked salmon?
1 kg salmon fillet. 400 g coarse salt. 50 g brown sugar. 1.5 g smoked salt.
What is the best way to smoke salmon?
After curing and drying the salmon, it's time to hot smoke it. Smoke it for 3-4 hours at 102 °C until it reaches an internal temperature of 63 °C. The best way to control the internal temperature when cooking is with a meat thermometer.
What are common mistakes when smoking salmon?
The timing depends on the fish and your taste, but leaving the dry brine on for too long will make the fish too salty. If you tend to be conservative with salt, take out thinner pieces early and opt for less time. One hour is too much; I've made that mistake.
