The recommended boiling time for crab legs is generally 5 to 8 minutes if they are pre-cooked and frozen, which is the most common type sold in stores. For fresh, raw crab legs, boiling time is longer, about 6 to 8 minutes or until the crab turns bright red and the meat is opaque. The crab legs just need to be heated through as most crab legs are pre-cooked and frozen when purchased. It is important not to overcook them to avoid rubbery meat. Here is a summary of boiling times for crab legs:
- Pre-cooked (frozen) crab legs: boil for 5 to 8 minutes.
 - Fresh/raw crab legs: boil for 6 to 8 minutes until fully cooked.
 
Instructions for boiling:
- Bring a large pot of salted water to a boil.
 - Submerge crab legs completely.
 - Reduce heat to medium and simmer covered for the recommended time.
 - Remove and serve with melted butter or dipping sauce.
 
This method ensures crab legs are heated perfectly without overcooking.
