Hot-smoked vs cold-smoked

Store-bought lox-style "smoked salmon" is usually cold-smoked: cured with salt and smoked at low temperatures that do not cook the fish. That process needs controlled conditions and is best left to commercial producers. Backyard smoked salmon is hot-smoked: the fish cooks through and flakes. This guide covers hot-smoking only.

Safety

USDA FSIS lists 145°F (62.8°C) for fish and shellfish on its safe minimum internal temperature chart. Measure in the thickest part of the fillet. Keep fish cold until it goes on the smoker, and thaw frozen fish in the fridge, never on the counter. Discard brine after use.

Brine or dry cure

Most hot-smoked salmon recipes start with a brine or dry cure of salt and sugar, which seasons the fish and firms the texture. Strength and time vary by recipe and thickness; follow a trusted recipe and keep fish in the fridge while it brines. Use the brine calculator to measure salt by weight. Rinse and pat dry.

The pellicle

After brining, many cooks let the fillets air-dry uncovered in the fridge for an hour or more until the surface turns tacky. This layer, called the pellicle, helps smoke stick and reduces white albumin seeping out during cooking.

Pit temperature

Fish is delicate. Many cooks smoke salmon at the lower end of the range USDA FSIS gives for smoking (225 to 300°F) to keep it moist and limit albumin. Even heat matters more than speed. Put the fish skin-side down on a lightly oiled rack or a plank; the skin protects the flesh and makes lifting easier.

Wood

Alder is the traditional wood for salmon in the Pacific Northwest. Fruit woods such as apple and cherry also suit fish; heavy woods like mesquite can overwhelm it. See the wood pairing chart.

Timing

Thickness rules timing. A thin tail end will be done long before a thick centre cut. Trim fillets to similar thickness or pull pieces as they finish. Use the smoking time calculator as a starting estimate, but check temperature early and often.

Worked example

Figures below are illustrative examples (2026-10-29), not quotes or guarantees.

Assumptions: a 3 lb side of salmon cut into 4 portions about 1 in thick, dry-cured 4 hours in the fridge, rinsed, pellicle formed for 1 hour, pit at 225°F, planning time about 1.5 h. Start checking thickest portion at 60 min, pull at 145°F. At about 6 oz per serving and an illustrative 85% yield, 3 lb feeds about 6 to 7 people.

Serving and storing

Serve warm or chilled, flaked over salads, in dips or on crackers. Refrigerate within 2 hours in a sealed container and eat within a few days. Hot-smoked salmon is not shelf-stable; keep it cold.

Common mistakes

• Treating hot-smoked salmon like cured lox and storing it at room temperature.
• Skipping the pellicle, so smoke does not adhere.
• Running the pit too hot and getting lots of white albumin.
• Cooking uneven pieces together and overcooking the thin ones.

Other fish

Trout, mackerel and other oily fish smoke well with the same approach. Lean white fish dries out faster and benefits from shorter cooks. All fish follow USDA FSIS's 145°F minimum.

Cuts and portions

A whole side of salmon looks impressive and is simple to serve, but it has thick and thin ends. Cutting it into even portions lets you pull each piece when it is ready. Skin-on portions hold together better. Pin bones can be pulled with clean pliers before brining. Fattier salmon species and farmed salmon are more forgiving on the smoker than lean wild fillets.

Glazes

Maple, honey or brown sugar glazes are popular with salmon. Brush them on in the last part of the cook so they set without burning. A glaze does not replace the thermometer check at 145°F.

Planks and foil

Cedar or alder planks soaked in water add aroma and keep fish off the grates. A sheet of perforated foil or a fish mat works too. Lift with a wide spatula from under the skin.

Smoked salmon dip

Flake cooled smoked salmon into cream cheese with lemon, herbs and a little pepper for a dip or spread. Keep it refrigerated and eat within a few days. Smoked fish dishes should not sit at room temperature more than 2 hours, consistent with USDA FSIS's guidance on perishable foods.

Planning for guests

For an appetizer, a little smoked salmon goes a long way. For a main course, plan full portions. Use the meat per person calculator and a high yield, since salmon loses less weight than fatty pork or beef.

Hot-smoked vs cold-smoked

This page covers hot-smoking, where fish is cooked to at least 145°F, per USDA FSIS. Cold-smoked salmon is a cured product made at low temperatures under controlled conditions and is not covered here.

Common mistakes

• Over-brining, which makes salmon too salty.
• Skipping the pellicle, so smoke does not stick well.
• Running the pit too hot, so white albumin beads out.
• Leaving it too long and drying the thin end; cut even portions.

Quick checklist

Brine briefly, rinse, dry to a tacky pellicle, light smoke, moderate heat, check the thickest part for 145°F, and serve or chill promptly. Keep raw fish cold until it goes on.

One more tip

Oil the grate or skin lightly so the fillet releases cleanly when you lift it off the smoker.

FAQ

Can I cold-smoke at home?

It needs strict temperature and curing controls; this site does not cover it.

Why is white stuff coming out?

That is albumin, a protein; a lower pit and pellicle help.

What temperature for the smoker?

Many cooks stay at the low end of 225 to 300°F.

How long does it last?

Refrigerated, a few days; freeze for longer.
