Smoked salmon is a popular ingredient in many sushi rolls and nigiri sushi. When dressed with rice and wrapped in nori seaweed the subtle smoky flavor and velvety texture of smoked salmon makes for a delicious bite. However there is often confusion around whether smoked salmon used in sushi is actually cooked or raw.
How Smoked Salmon is Prepared
Smoked salmon begins its journey as raw fresh salmon. The salmon is first cured or brined in a salt solution, often with added sugar and spices. This curing process helps draw moisture out of the fish while infusing it with flavor. The salmon is then placed in a smoker where it is exposed to smoke at low temperatures, usually around 70-90°F. This temperature is not high enough to cook the salmon, but the smoke helps preserve and further flavor the fish.
The end result is salmon with a firm, silky texture and deep smoky aroma and taste However, since the salmon is not heated to safe minimum internal temperatures for fish of 145°F, it is not considered fully cooked from a food safety standpoint
Is Smoked Salmon Safe to Eat Raw?
While not cooked, properly cured and smoked salmon is safe to eat raw. The salt and smoke used during processing reduce the risk of harmful bacteria growth. Salmon intended for raw consumption is first frozen to kill any parasites before being cured and smoked. Reputable sushi restaurants always use high-quality frozen salmon to craft their smoked salmon sushi.
As long as smoked salmon comes from a trusted source, it carries minimal risk of foodborne illness. Pregnant women and those with compromised immune systems should take extra care and consult their doctor before eating raw smoked salmon. But for most healthy individuals, smoked salmon sushi is perfectly safe to enjoy.
The Texture of Smoked Salmon
One of the biggest giveaways that smoked salmon is not cooked is its raw, velvety texture. Fully cooked salmon becomes opaque and flakes easily when poked with a fork. Smoked salmon retains its signature smooth, supple flesh that seems to melt in your mouth.
Smoked salmon also has a distinctly soft and lush mouthfeel. Cooked salmon tends to be drier and firmer. So when eating smoked salmon sushi, appreciate its buttery texture as a sign of its lightly cured, but ultimately raw, state.
Smoked vs Baked Salmon
Sometimes smoked salmon can get confused with baked salmon, another popular sushi ingredient. Baked salmon is cooked to safe internal temperatures, usually in a low-temp oven. This gives it a firmer, cooked texture while still retaining moisture.
On a sushi menu, baked salmon is always labeled as such and not simply called smoked salmon. It will look more opaque and dry compared to the glistening sheen of raw smoked salmon. So don’t let the term “smoked salmon” mislead you into thinking it’s cooked. Always check if it is specified as baked or smoked.
Cooking Smoked Salmon
While delicious raw, smoked salmon can also be lightly cooked to give it a warmer, flaky texture. Options like quickly searing or pan-frying smoked salmon help reduce any concerns about raw consumption while adding nice caramelized bits.
Smoked salmon also takes well to gentle poaching and steaming. You can toss flaked smoked salmon on top of rice bowls, scrambled eggs, pasta, and salads for a protein boost. Lightly warming smoked salmon helps release even more of its complex flavors.
Safely Storing Smoked Salmon
To safely enjoy raw smoked salmon, proper storage is key. Keep smoked salmon refrigerated at 38°F or below and use within 3-5 days of opening. Do not allow the fish to sit out at room temperature for more than 2 hours before discarding. Check for signs of spoilage like dull coloration, dry texture, or an unpleasant odor.
For longer storage, smoked salmon can be frozen for 2-3 months. Defrost in the refrigerator before using. Carefully follow handling instructions for any ready-to-eat seafood like smoked salmon.

Methods Used to Smoke Salmon
Below are a few common methods for smoking salmon:
- Hot Smoking: In this method, the salmon is exposed to heat and smoke. The fish is typically cured with a salt and sugar mixture, then smoked at temperatures between 120°F and 180°F (49°C to 82°C). The heat cooks the salmon while the smoke infuses it with flavor. Hot smoking results in a fully cooked and flaky texture.
- Cold Smoking: By comparison, cold smoking techniques use temperatures below 90°F (32°C) for an extended period, often 12 to 24 hours or more. This method imparts a smoky flavor without fully cooking the fish. Cold smoking requires a separate smoke source and a chamber to keep temperatures low. The salmon is typically cured before the smoking process to enhance flavor and preservation.
- Combination Method: Some recipes use a combination of hot and cold smoking techniques. The salmon may be initially hot smoked to partially cook it and develop flavor, and then finished with a cold smoking process to infuse a more pronounced smoky taste.
- Wood Chip Varieties: Various smoking wood chips impart unique flavor profiles. Common woods used include oak, alder, hickory, apple, cherry, and maple.
