Crab legs are usually sold pre-cooked, so the main task is to heat them gently without drying out the meat. When done right, the meat stays sweet, juicy, and tender.
How to cook crab legs
To cook crab legs, reheat them using steam, boiling, or baking just until hot throughout. Overcooking is the most common mistake.
