Let’s start with the fundamentals – the different types of crab legs available and their characteristics.

Types of Crab Legs

There are several varieties of crab legs commercially fished and sold. Here are some of the most common:

  • Snow crab legs – Snow crab, also called Queen crab, are known for their long, thin legs and sweet, delicate flavor. Most snow crab legs come from Alaska or Canada.
  • King crab legs – King crab legs are larger and meatier than snow crab legs, with a slightly sweeter, richer taste. Red king crab and blue king crab are two main types.
  • Dungeness crab legs – From the Pacific Northwest, Dungeness crab legs are shorter and plumper than other crab legs, with a mild, briny flavor.
  • Stone crab legs – Stone crabs have large, meaty claws that are the main edible portion. The claws have firm, tasty meat.

Snow Crab vs. King Crab

Snow and king crab are two of the most popular varieties. Here’s how they compare:

  • Taste – King crab is sweeter and more succulent. Snow crab has a delicate, slightly milder flavor.
  • Texture – King crab meat is firmer and chunkier. Snow crab is softer, with thin strands of meat.
  • Size – King crab legs are much larger and meatier. Snow crab legs are long but thin.
  • Cost – Due to limited supply, king crab costs more per pound than snow crab.

Health Benefits

Crab legs provide excellent nutritional value:

  • Protein – High quality, lean source of protein needed for energy and muscle maintenance.
  • Omega-3s – Heart healthy fats that reduce inflammation.
  • Vitamin B12 – Important for nerve tissue and red blood cell health.
  • Zinc and copper – Immune system supporting minerals.

Crab legs are low in mercury and a cholesterol-free food.


Some crab fisheries have struggled with overfishing. Look for certification from organizations like the Marine Stewardship Council when purchasing crab legs to ensure sustainability.

Preparation Essentials

Proper preparation is key for cooked crab leg perfection.

Cleaning and Prepping

Thoroughly rinse raw crab legs under cold water. Use a stiff brush to scrub the shell. Remove any top shell segments on king crab legs to expose meat. Pat the crab legs dry completely with paper towels.

Portion Size

For a main course, estimate 1⁄2 to 1 pound of crab legs per person. Adjust based on appetite and accompanying dishes.


For best flavor and texture, thaw frozen crab legs overnight in the fridge. Quick thaw by placing legs in a colander under cold running water for 30 minutes.
