Add the raw crab legs to the rapidly boiling water or steamer. If using a steamer, cover. Allow the crab legs to boil for about six or eight minutes for smaller legs like snow crab and as long as 12 to 14 minutes for very large legs like some king crab varieties. If using a steamer, steam for 12 to 14 minutes for small legs and 20 to 24 minutes for large legs.
Step Three, once the water is boiling, you place the crab legs into the steamer. Cook the crab through, steaming them for 15-20 minutes, till they are good and hot, if the crab legs have been frozen, or steam them 10-12 minutes if the crab legs are already thawed or are fresh.
