How long do you cook Alaskan king crab legs?

To cook Alaskan king crab legs, bring a large pot of salted water to a boil. Add the crab legs and cook for 4-6 minutes if they are pre-cooked, or about 8-10 minutes if they are raw. If you prefer steaming, place the legs in a steamer basket over boiling water and steam for about 6-8 minutes. Always check that the meat is heated through and serve with melted butter for the best flavor.
