What temperature for sous vide fish?

By Paulo de VriesLast verified 2026-05-214 sources~3 min readhigh consensus

Salmon: 122°F (50°C) for 30-40 min = silky raw-ish. 130°F (54°C) for traditional medium. Cod/halibut: 132°F (56°C) for 30-45 min. Tuna: 110°F (43°C) for sashimi-style. Most popular: salmon 125°F (52°C) for 35 min = silky-tender + pasteurized.

The full answer

Why sous vide fish is shorter cooking

Fish proteins are more delicate than meat. They denature at much lower temperatures (~120°F) and become unpleasantly firm + dry above 140°F. Sous vide preserves their delicate texture while still ensuring even cooking + safety.

Temperature ranges by fish type

Fish	Temperature	Time	Texture
Salmon	122°F (50°C)	30-40 min	Silky raw-ish, restaurant-style
Salmon	125°F (52°C)	35-45 min	Slightly firmer, traditional medium-rare
Salmon	130°F (54°C)	30-40 min	Medium, traditional
Salmon	140°F (60°C)	30-40 min	Firm, well-done
Cod/halibut	130°F (54°C)	30-45 min	Flaky + just-set
Cod/halibut	132°F (56°C)	30-45 min	Firmer flake; traditional
Tuna	110°F (43°C)	30 min	Sashimi-style; warm raw center
Tuna	120°F (49°C)	30-40 min	Rare; pinkish center
Sea bass	122°F (50°C)	30 min	Silky
Trout	125°F (52°C)	35 min	Traditional medium
Swordfish	130°F (54°C)	30 min	Medium

Pasteurization for fish (FDA guidance)

For raw-fish-grade safety, FDA recommends: - Wild-caught freshwater fish: freeze at -4°F for 7 days before raw consumption (kills parasites) - Sushi-grade salmon: sourced as "previously frozen for raw consumption" or treated similarly - Sous vide pasteurizes via time × temp: at 122°F, 1 hour = pasteurized for most fish; at 130°F, 15-20 min

For most home cooking, 30-45 min at 122-130°F = both delicious + safe.

Common pitfalls

Overcooking — fish cooks fast. 60+ min at 122°F = mushy. Set timer and stop.
Bag bursts — fish skin releases small bubbles during cook; use double-bag or check seal periodically
Skin texture — sous vide softens skin. For crispy skin: sear in screaming-hot pan post-cook (30-60 sec skin-side down)
Wet fish — pat dry thoroughly before sear; otherwise no browning
Wrong fish type — meaty fish (halibut, swordfish) sous vide differently than oily fish (salmon). Match temperature to fish type.

Best practice

Pat fish dry. Season: salt, pepper, herbs, sometimes butter or oil
Bag with optional flavor enhancements (citrus zest, fennel, dill, white wine — never raw garlic for >4 hour cooks)
Submerge in pre-heated bath
Cook for 30-45 min (most fish/cuts)
Remove + pat dry completely
Optional skin-side sear in screaming-hot pan (30-60 sec)
Plate immediately

Time ranges by condition

Condition	Duration	Note
Salmon, 122°F / 50°C	30-40 min	Silky raw-ish, restaurant-style
Salmon, 130°F / 54°C	30-40 min	Traditional medium
Cod/halibut, 132°F / 56°C	30-45 min	Flaky just-set
Tuna, 110°F / 43°C	30 min	Sashimi-style warm raw center
Trout/sea bass, 125°F / 52°C	35 min	Silky, traditional

What changes the time

Fish thickness. 0.75-1.25" most common. Thinner: reduce by 5-10 min. Thicker (1.5"+): add 5-10 min.
Fish freshness. Day 0-1 from catch = best. Day 2-3 = OK. Day 5+ = sulfur risk in vacuum bag — cook quickly.
Sushi-grade requirement. For lower temps (under 125°F), use sushi-grade or previously-frozen fish for parasite safety
Skin-on vs skinless. Skin-on = sears crispier post-cook. Skinless = easier eating but no crispy crust.

Common questions

My salmon turned out chalky white — what went wrong?

Overcooked. Above ~135°F, salmon's albumin protein coagulates + appears as the white "stuff" on top. For silky salmon: stick to 122-125°F for 30-40 min. If you overcooked: serve it sliced over salad (texture is still acceptable just-cooked) but next time pull temp down. The chalky white texture means proteins fully denatured + lost moisture.

Can I sous vide frozen fish without thawing?

Yes — add 5-10 extra minutes to the cook time + ensure thorough thawing during cook. Most sous vide circulators are powerful enough to thaw + cook in one go. Use bag-water-displacement method (not vacuum) to ensure ice doesn't puncture the bag. Frozen-cooked salmon is fine; for sushi-grade outcomes, thaw first to inspect quality before bagging.

Why does sous vide salmon taste different from pan-seared?

No Maillard reaction from the sous vide itself = no roasted/crusty flavor compounds. The fish texture stays much more delicate + silky, more like raw or just-poached. The flavor is purer + closer to the fish's natural taste. For more "cooked" flavor: sear sous vide fish in hot pan 30-60 sec per side after cooking — this adds Maillard browning + restores some traditional cooked-fish flavor.

honest uncertainty

We don’t know your specific equipment, ingredient batch, or environment. This answer is the best directional estimate from cited sources. Here’s where it’s less certain:

4 factors shift the answer. Your specific fish thickness, fish freshness, sushi-grade requirement (and more) can move this estimate in either direction. The table below shows the documented ranges.
Range spans 5 documented conditions. Pick the row that matches your scenario; halfway between two rows is your best estimate. The widest condition you can imagine is the safer upper bound.
Treat as a directional starting point. Real-world equipment, ingredient batch, and ambient conditions cause natural variance the table cannot capture. Use sensory checks (sight, smell, touch, internal temperature when relevant) alongside this answer — not instead of it.
Backed by 4 cited sources — verify if precision matters. See the Sources section for primary references. Cross-check the cited materials when stakes are high: commercial production, food safety, allergens, dietary or medical considerations.
