The Complete Guide to Wild Sablefish (Black Cod)
Rich, buttery, deeply marbled — Sablefish is one of the most omega-3-dense fish in Alaska and one of the most prized in the culinary world. Often mistakenly called "black cod," it's not actually a cod at all. Here's everything to know.
Key takeaways
- About 3,000 mg of EPA + DHA per 6 oz cooked serving — sablefish flesh is naturally rich in oils, and by USDA data it has about twice as much EPA + DHA as sockeye.
- Buttery, velvet-rich texture — comparable to Chilean sea bass but better-managed.
- "Black cod" is a misnomer — sablefish (Anoplopoma fimbria) isn't a cod. It's its own family entirely.
- From an MSC-certified fishery — Alaska's sablefish (black cod) fishery is certified sustainable by the Marine Stewardship Council (US North Pacific halibut and sablefish). Strict science-based quotas.
- Wild-caught in Alaska — by other Alaska fishermen, not our family (our own permits are for salmon), and packed under the Popsie name.
- Notoriously difficult to overcook — the high oil content gives a forgiving 2-3 minute window of perfect doneness.
What is Sablefish?
Anoplopoma fimbria — Sablefish — is a deep-water fish found from Baja California up through the Bering Sea, with the highest concentrations in Alaska. The name "black cod" comes from the dark grey-to-black skin, but it's a confusing nickname: sablefish are not cod, not related to cod, and are in a completely different scientific family (Anoplopomatidae) than true cods (Gadidae).
Sablefish live deep — 1,000 to 3,000 feet — and grow slowly. They can live 90+ years, which is one reason Alaska's quota system is so carefully managed. Adults typically run 5-10 pounds; the largest can exceed 30 pounds.
How to identify quality Sablefish
Premium sablefish has the texture of butter and the appearance of marbled meat. Raw, the flesh is white-to-pale-pink with visible streaks of oil running through it (this is the marbling — it's the good stuff, not a defect). Cooked, it flakes into large, glossy, snow-white pieces that melt on the tongue. The flavor is mild but luxurious — clean, slightly sweet, deeply rich.
Where Popsie's Sablefish comes from
Our Sablefish is wild-caught in Alaska by other Alaska fishermen, and we sell it under the Popsie name alongside the sockeye our family catches on our own Bristol Bay setnet sites. Sablefish is one of the most heavily-regulated fisheries in the world — Alaska's Individual Fishing Quota (IFQ) system limits how much each vessel can catch annually, and most boats fish the same grounds year after year, developing deep knowledge of the resource. After landing, fish are processed and flash-frozen at peak freshness.
Sustainability
Alaska's sablefish (black cod) fishery is certified sustainable by the Marine Stewardship Council (US North Pacific halibut and sablefish). The IFQ system has prevented the race-to-fish behavior that plagues many fisheries, allowing fishers to harvest during optimal conditions for quality and minimum waste.
Nutrition: an omega-3 heavyweight
Sablefish is one of the most omega-3-dense fish in Alaska. A 4 oz raw portion has about 1,600 mg of EPA + DHA, about twice as much as the same portion of wild sockeye (about 820 mg), per USDA. It's also an excellent source of selenium and vitamin B12.
| Per 4 oz raw portion | Sablefish |
|---|---|
| Calories | ~220 |
| Protein | ~15 g |
| Total fat | ~17 g |
| Omega-3 (EPA+DHA) | ~1,600 mg |
| Vitamin B12 | 1.7 mcg (71% DV) |
| Selenium | 41 mcg (75% DV) |
Source: USDA FoodData Central, sablefish, raw (FDC 175134).
The fat in sablefish is predominantly unsaturated, including the long-chain omega-3s EPA and DHA. Because sablefish carries more mercury than salmon or cod, the FDA/EPA Advice about Eating Fish (revised October 2021) lists it as a "Good Choice": 1 serving a week.
How to cook Sablefish
Sablefish is the easiest fish in the wild Alaskan lineup to cook well — the high oil content gives a forgiving 2-3 minute window between "perfect" and "slightly over." The flesh stays moist and tender even when you push it longer than ideal.
Miso-glazed (the classic)
The most famous sablefish preparation — Nobu's miso-marinated black cod. Marinate fillets in white miso, sake, mirin, and sugar for 24-72 hours, then broil 3-4 minutes until the surface caramelizes. The result is sweet, rich, almost dessert-like.
Pan-seared (5-7 min)
Pat dry, season simply with salt and pepper. Skin-side down in a hot pan with a touch of neutral oil. 3-4 minutes for crispy skin, flip and cook 2-3 minutes more. The high oil content means you don't need to add fat — the fish renders its own.
Smoked (cold or hot)
Smoked sablefish is a delicacy — buttery flesh + smoke is one of the great food combinations. Cold-smoked sablefish (often labeled "sable" at deli counters) is silky and meaty. Hot-smoked is flakier and more pungent. Both are extraordinary on bagels with cream cheese.
Poached in butter
Fillets in a pan, butter, herbs (thyme + lemon zest), low heat 8-10 minutes until just barely opaque. Spoon the butter over the fish as it cooks. Serve with the buttery liquid as a sauce. It will taste like a 4-star restaurant.
Pro tip: Don't overthink seasoning. Sablefish carries its own flavor so well that simple preparations (salt, pepper, butter, lemon) often outperform elaborate ones. Save the bold flavors (chiles, fermented sauces) for milder fish.

FAQ
Is sablefish the same as black cod?
"Black cod" is a common nickname for sablefish (Anoplopoma fimbria), but it's not actually a cod — they're in completely different scientific families. The "black" refers to the dark skin. You'll see both names on menus and packaging; same fish.
How does sablefish compare to Chilean sea bass?
Sablefish has a similar buttery texture and is often used as the more sustainable alternative to Chilean sea bass (Patagonian toothfish), which has serious overfishing concerns. Alaska's sablefish fishery is certified sustainable by the Marine Stewardship Council and well-managed.
Why is sablefish more expensive than other fish?
Three reasons: it grows slowly (so Alaska's quota system limits annual harvest), it's caught in deep water (which is operationally expensive), and the high-end restaurant market drives strong demand. The price reflects the quality — sablefish is rightly considered one of the world's premier fish.
What does sablefish taste like?
Rich and buttery, but mild — not fishy. Think halibut texture × salmon richness × cod mildness. The high oil content makes it almost dairy-like in mouthfeel. If you've never had it, the first bite will surprise you.
How long does frozen sablefish last?
Vacuum-sealed and stored at 0°F or below, sablefish keeps its best quality for 6-12 months. The high oil content means it's more prone to slow oxidation than leaner fish, so use it toward the start of that window for the best flavor. Once thawed, cook within 1-2 days.
Can you cook sablefish from frozen?
Yes — sablefish is forgiving. For pan-searing, thaw partially (15-20 min in cold water) for best skin crisp. For miso marinades, you'll need to thaw fully so the marinade penetrates. For broiling and baking, you can go straight from frozen — just add 50% to your cook time.
