The Ultimate Guide to Buying King Crab Online – How to Choose Premium Crab
September 13, 2024The Ultimate Guide to Buying King Crab Online
King crab is one of the most prized seafood products in the world — large, meaty legs with sweet, rich, buttery flesh that requires almost no preparation to be extraordinary. Buying king crab online gives you access to wild-caught Alaskan crab that most local markets can't match in quality or variety. This guide covers the species differences, what to look for when ordering, how to store and reheat, and what to avoid.

King Crab Species: Red vs. Golden
Most consumers don't realize that "king crab" refers to multiple species with meaningfully different flavors, sizes, and price points. The two most commonly sold are red king crab and golden king crab.
Red King Crab (Paralithodes camtschaticus)
The largest and most prized king crab species. Red king crab is caught primarily in the Bering Sea and Gulf of Alaska, with the most famous fishery centered around Dutch Harbor, Alaska — the setting of the TV series Deadliest Catch. The legs are massive (jumbo legs can weigh ½ lb or more each), the meat is sweet, rich, and buttery, and the yield per leg is exceptional. Red king crab is the benchmark against which all other crab is measured.
- Flavor: Rich, sweet, buttery; the most intense king crab flavor
- Size: Largest of the king crab species; legs can span 5+ feet tip to tip on a live crab
- Price: Most expensive; reflects the difficulty of the fishery and the quality of the product
- Best for: Special occasions; dinner party centerpieces; simple preparations (steamed with butter) where the flavor can shine

Golden King Crab (Lithodes aequispinus)
A distinct species from red king crab, caught at deeper depths (600–1,400 feet) in the Aleutian Islands and Gulf of Alaska. Golden king crab is smaller than red king crab but has a more delicate, subtly sweet flavor that many seafood enthusiasts prefer for its nuance. The shells are thinner and easier to crack; the meat is slightly more tender. Because it's caught at greater depths and in smaller quantities, it's less well-known than red king crab — but it's an exceptional product.
- Flavor: Delicate, subtly sweet; more nuanced than red king crab; slightly less rich
- Size: Smaller than red king crab; legs are thinner but still substantial
- Price: More affordable than red king crab; excellent value for the quality
- Best for: Weeknight indulgences; pasta and risotto (where the delicate flavor won't be overwhelmed); guests who find red king crab too rich
What to Look for When Buying King Crab Online
Wild-Caught vs. Farmed
All commercially sold king crab in the US is wild-caught — king crab has not been successfully farmed at commercial scale. "Wild-caught" on a king crab label is accurate but not a differentiator; what matters more is the specific fishery and how the crab was handled post-catch.
Sourcing Region
Alaska (Bering Sea, Gulf of Alaska, Aleutian Islands): The gold standard for king crab. Alaskan king crab fisheries are among the most tightly regulated in the world — managed by the Alaska Department of Fish and Game with strict quotas, size limits, and season lengths. The cold, nutrient-rich waters of the Bering Sea produce the largest, sweetest crab.
Norway: Red king crab was introduced to the Barents Sea in the 1960s by Soviet scientists and has since established a large wild population. Norwegian king crab is high quality and comparable to Alaskan crab in flavor; it's harvested under Norwegian fisheries management. A legitimate and excellent sourcing region.
Russia: The Russian Far East (Sea of Okhotsk, Kamchatka) has significant king crab populations. Quality can be excellent but regulatory oversight varies; look for suppliers who can verify the specific fishery and handling practices.
Japan: Japan imports and processes king crab from Russia and Alaska; "Japanese king crab" typically refers to crab processed in Japan rather than caught there. Japanese processing standards are high; the product is excellent but the origin is usually Alaskan or Russian.
Fresh vs. Flash-Frozen
For online purchase, flash-frozen is almost always the better choice — and often the only realistic option. King crab is pre-cooked on the fishing vessel immediately after harvest and then flash-frozen at sea or at the processing facility. This locks in peak freshness. "Fresh" king crab sold online has typically been thawed from frozen and refrozen, or is previously frozen and thawed for shipping — which is not superior to buying frozen and thawing yourself. Buy frozen; thaw properly; the quality will be excellent.
Size Grades
King crab legs are sold by size, typically measured as the number of legs per 10 lbs:
- 6/9 (Colossal): 6–9 legs per 10 lbs; the largest available; most impressive presentation
- 9/12 (Jumbo): 9–12 legs per 10 lbs; excellent size; the most popular grade
- 12/14 (Large): 12–14 legs per 10 lbs; good value; slightly smaller
- Leg pieces / clusters: Pre-cut sections; more affordable; same flavor as whole legs
For a dinner party centerpiece: 6/9 or 9/12. For everyday use or pasta/risotto: leg pieces or clusters.
How Much to Order
| Occasion | Amount per Person |
|---|---|
| Appetizer | ½–¾ lb king crab legs |
| Main course (with sides) | 1–1½ lb king crab legs |
| Main course (crab only) | 1½–2 lb king crab legs |
Example: Dinner party of 6, king crab as the main course with sides — order 6–9 lbs of king crab legs.
Storing and Reheating King Crab
Storage
- Frozen (unopened): Keep in freezer; best quality within 3 months; safe up to 6 months
- After thawing: Refrigerate; consume within 2 days; do not refreeze thawed crab
- Thawing method: Overnight in the refrigerator (best); cold water submersion for 1–2 hours (faster); never at room temperature or in warm water
Reheating: What Works and What Doesn't
King crab sold online is pre-cooked — you're reheating, not cooking from raw. The goal is to warm the meat through without drying it out or leaching the flavor.
- Steaming (best method): 1–2 inches of water in a large pot; steamer rack; cover and steam 5–7 minutes (thawed) or 10–12 minutes (frozen). The meat stays moist and the flavor is fully preserved.
- Grilling (excellent for flavor): Split legs lengthwise with kitchen shears; brush with butter; grill cut-side down over medium-high heat 3–4 minutes; flip 2 minutes. Adds light char and smoky depth.
- Oven (convenient): Wrap tightly in foil with a splash of water or butter; bake at 350°F for 10–15 minutes (thawed) or 20–25 minutes (frozen). The foil traps steam.
- Boiling (avoid): Boiling pre-cooked crab legs leaches the flavor into the water and makes the meat watery and bland. If you must boil, use heavily salted water and limit to 3–4 minutes.
- Microwave (avoid): Uneven heating; some sections become rubbery while others are still cold.

FAQs: Buying King Crab Online
Is flash-frozen king crab as good as "fresh" king crab?
For online purchase, flash-frozen king crab is almost always the better choice — and often superior to what's sold as "fresh." Here's why: king crab is pre-cooked on the fishing vessel immediately after harvest, then flash-frozen at sea or at the processing facility. This locks in peak freshness at the moment of maximum quality. "Fresh" king crab sold online has typically been thawed from frozen and is being shipped refrigerated — it's not fresher than frozen; it's just been thawed earlier in the supply chain, giving it a shorter window before it must be consumed. Buying frozen and thawing yourself gives you control over timing and ensures the crab hasn't been sitting thawed in transit. The quality of properly flash-frozen king crab is indistinguishable from fresh-off-the-boat crab to most consumers.
What's the difference between red king crab and golden king crab?
They are distinct species with different flavors, sizes, and price points. Red king crab (Paralithodes camtschaticus): the largest and most prized; caught in the Bering Sea and Gulf of Alaska; rich, sweet, buttery flavor; the most expensive. Golden king crab (Lithodes aequispinus): a separate species caught at deeper depths (600–1,400 feet) in the Aleutian Islands; smaller than red king crab; more delicate, subtly sweet flavor; thinner shells that are easier to crack; more affordable. The choice depends on your preference and occasion: red king crab for maximum impact and richness; golden king crab for a more nuanced flavor and better value. Both are exceptional products.
How do I know if my king crab has been properly handled and is safe to eat?
Signs of properly handled king crab: Frozen — the legs should be solidly frozen with no signs of freezer burn (white, dry patches on the surface); the packaging should be intact with no tears or ice crystals inside (which indicate temperature fluctuation during storage). After thawing — the meat should be white to ivory with red/orange shell coloring; it should smell clean and oceanic (not fishy or ammonia-like); the texture should be firm, not mushy. Red flags: strong fishy or ammonia smell; mushy or slimy texture; gray or discolored meat; excessive ice crystals in the packaging (indicates freeze-thaw cycles). Buy from reputable suppliers who can provide information about sourcing, processing, and cold chain handling. King crab from established seafood retailers with high turnover is significantly lower risk than crab from unknown sources.
