Why Baking King Crab Legs Works So Well

Baking crab legs is one of the easiest ways to create a flavorful seafood dinner because the oven gently steams the crab while reheating it evenly.

You can keep the flavors simple with lemon and butter or add garlic cloves, fresh herbs, and thyme for even more flavor.

How to Make Oven Baked King Crab Legs

STEP FOUR: Add Water and Cover

Pour about 1/8 inch of hot water into the bottom of the baking dish or use white wine for more of a scampi flavor

Cover the entire dish tightly with aluminum foil. This step is important because it creates steam inside the pan, helping prevent the crab legs from drying out while reheating.

Bake for about 10 minutes or until the crab legs are evenly heated through and steaming hot.

Remove from the oven carefully, uncover, and allow them to cool for a few minutes before serving.
