Quick answer
Salmon fillet smokes at 225°F for about 60 minutes per pound. A 1–4 lb cut takes 1h–4h plus a 5-minute rest. Pull at 145°F internal. Do not wrap — this cut benefits from full bark exposure.

About salmon fillet
Hot-smoked salmon is in a different category from cold-smoked lox — it's fully cooked, smoky, and meant to be eaten warm or chilled. The technique uses low smoker temperatures (180–200°F) over fruit or alder wood to gently cook the fish while infusing smoke flavor. Weights typically run 1–4 pounds per fillet. Salmon takes brining seriously: a 12-hour dry brine before smoking is the single biggest factor in good results, drawing out moisture and creating the firm-but-flaky texture that defines good smoked salmon.
Buying salmon fillet
Fresh, skin-on salmon fillets are ideal. Wild-caught (sockeye, king, coho) has more flavor and firmer flesh than farmed Atlantic, but farmed works too and is more affordable. Look for bright flesh and clean smell. Frozen salmon thawed in the refrigerator works fine; in fact, most 'fresh' supermarket salmon was previously frozen.
Technique and pitfalls
Dry-brine 12 hours ahead with a mix of kosher salt and brown sugar (1:1 by weight) covering the entire fillet. Rinse, pat dry, and air-dry on a rack in the refrigerator for 1–4 hours — this forms the 'pellicle,' a tacky surface that holds smoke. Smoke at 180–200°F over alder, apple, or maple wood to 145°F internal. Optionally brush with a maple-syrup glaze in the last 20 minutes.
Internal temperature and wrap timing
Pull the salmon fillet when the thickest part hits 145°F on a probe thermometer. Probe-tender — the probe slides in like warm butter — is the more reliable signal than temperature alone; some cuts finish a few degrees above or below the target depending on the individual piece.
Do not wrap this cut. Smoking unwrapped preserves bark texture and is appropriate for cuts that finish at lower internal temperatures (poultry, lamb leg, tri-tip) where the stall is less of an issue.
Best wood for salmon fillet
Alder is the Pacific Northwest classic and the safest bet. Apple and maple work well. Avoid hickory, oak, and mesquite — all overpower salmon.
Common mistakes
Skipping the dry brine (soft, unappealing texture). Not letting the pellicle form (smoke doesn't adhere). Smoking too hot (180–200°F max — higher temperatures cook out the moisture too fast).

Frequently asked
How long does it take to smoke salmon fillet at 225°F?
About 60 minutes per pound at 225°F. A 1 lb takes ~1h; a 4 lb takes ~4h. Add a 5-minute minimum rest. Always pull at internal temperature, not by clock.
What internal temperature should salmon fillet reach?
Pull at 145°F internal temperature, measured in the thickest part with a probe thermometer. Do not rely on cooking time alone.
Should I wrap salmon fillet during the smoke?
No — this cut is best smoked unwrapped to retain bark and texture.
How long should salmon fillet rest after smoking?
Rest at least 5 minutes wrapped, ideally longer for larger cuts. Resting redistributes juices and finishes carryover cooking. Slicing early dries the meat.
What is the best wood for smoking salmon fillet?
Alder is the Pacific Northwest classic and the safest bet.
