There is nothing quite as indulgent as cracking into sweet, succulent crab legs dripping with garlic butter. This recipe takes the classic steamed crab leg experience and elevates it by baking the legs in a garlic herb butter that bastes them as they heat through, infusing every bite with rich, aromatic flavor.
Because king crab legs are sold pre-cooked, this dinner comes together in about 20 minutes — most of which is just oven time. The hardest part is waiting for them to come out. Serve them with extra melted butter for dipping, corn on the cob, and maybe a crisp white wine for one of the most memorable dinners you can make at home.

Tips & Storage
Pro Tips
Thaw frozen crab legs in the refrigerator overnight for the best texture. In a pinch, run them under cold water for 10 minutes.
Use kitchen shears rather than a knife to open the shells — it is much safer and easier.
Provide plenty of napkins, a shell cracker, and a bowl for discarded shells.
The cooking time is just for reheating — the crab is already cooked. Do not overbake or the meat becomes tough.
Storage
Store leftover crab meat (removed from shells) in an airtight container for up to 2 days. It is delicious cold in crab salad.
Reheating
Steam briefly over boiling water for 3-4 minutes or microwave with a damp paper towel for 1-2 minutes. Gentle is key.
