What is a King Crab, anyway?

Let’s back up for a sec before we roast this beastie.

I don’t know about you, but to me, King Crab has always been one of those capital “F” Fancy Foods. It’s right up there with filet mignon and oysters rockafeller. It’s a major player in classic steakhouse surf n’ turf. It feels like it should be complicated to make.

But what, exactly, is King Crab?

There are about 121 species of the prickly, cold water King Crab scrambling around in the seas. Three are most commonly used for food: the red king crab (most prized for flavor), blue king crab (sought out for its sweet meat and giant claws), and golden king crab (the smallest of the three and mildest in flavor).

As with most seafood, there are fishing requirements (size and sex…only males can be kept for food). In the U.S., we catch King Crab up in Alaska (hence, Alaskan King Crab). Alaska’s largest harvest takes place in Bristol Bay, where the King Crab population is abundant and healthy.

As you can tell by the monstrous size of their legs, they’re really big. (Yikes!)

The crabs are a dark, wine red when they’re alive, and bright red when they’re cooked. The meat is snow white, with bright red highlights.

Oh, and it’s notoriously dangerous work to trap them. So before you sit down to dine, say a word or two of thanks to the brave fishermen who fought freezing temps and turbulent seas to bring them to your market. King Crab fishing is the subject of the Discovery Channel’s popular show, Deadliest Catch. (For more fishing facts, Deadliest Catch’s website has a great section called Crab Fishing 101. Check it out here.)

Did you know?

If that wasn’t enough info about King Crab for ya, here are a few more facts:

  • King Crab legs have a size rating, similar to shrimp. They’re measured by how many legs make up 10 lbs. So, a size of “6-9” means 6-9 legs would weigh 10 lbs. Basically, the smaller the size rating, the bigger the legs.
  • While we all know about the legs, King Crab claws are also reportedly very tasty. If you have the chance to try them, jump at it!
  • King Crabs can live upwards of 20 years.
  • Protein-rich King Crab has no carbs and almost no fat
