How to Steam Frozen Crab Legs

Steaming crab is the ideal way to prepare wild-caught Alaskan crab legs to serve it with a dip or enjoy it on its own. It's quick to do and is the easiest way to preserve the moist, tender texture of crab meat. Unlike boiled crab, steamed crab retains more of its own juices and flavors. 

Steaming crab could not be simpler. Even if you don't have a steamer on hand, it does not require special equipment and can be done in a standard pot in ten mnutes or less. 

Equipment for Steaming Frozen Crab Legs

To steam frozen crab legs you will need a steamer pot, or a large pot with a colander and a lid. Alternatively, you can use any pan fitted with a lid, and put a shallow layer of water inside. 

You can steam the crab legs in plain water or flavor the water with salt and optional aromatics like lemon slices, garlic, seasoning or any herbs. 

Should You Thaw Frozen Crab Legs Before Steaming?

It's up to you. You can either thaw frozen crab legs before steaming them, or steam crab legs from frozen. Because of their size, crab legs can be steamed from frozen efficiently while retaining the quality of the meat. 

If steaming frozen crab legs, rinse off any thicker areas of ice glaze under cold, running water. This will help ensure even heating.

How Long to Steam Crab Legs

Alaskan crab that is still frozen takes slightly longer to steam than crab that has been thawed. Either way, it takes 10 minutes or less to steam crab legs: 

• Steaming Alaskan crab legs from frozen: about 10 minutes

• Steaming thawed Alaskan crab legs: about 5 minutes

How to Steam Frozen or Thawed Crab Legs

Gather your materials: Crab legs and claws (frozen or thawed); a steamer basket that fits in a lidded pot, or a wide lidded pot or pan; lemon slices

If using a steamer basket, fill a pot with an inch of water, then add a few lemon slices. Cover with lid, then bring water to a simmer over medium heat until steaming.

Once pot is steaming, add crab legs and cover with lid. Continue to steam over medium heat for 5 minutes if using defrosted crab; 10 minutes if using frozen crab. 

If not using a steamer basket, simply cover the bottom of a wide pot or pan with about ¼ inch of water and add a few lemon slices. Cover with lid and bring to a simmer over medium heat until steaming. Then, add crab legs and cover with lid. Continue to steam over medium heat for 5 minutes if using defrosted crab; 10 minutes if using frozen crab. 

Tips for Heating and Eating Frozen Crab Legs

• If crab legs are split, do not fully submerge in water, rinsing is fine

• If your crab is fully cooked before freezing, you may simply thaw in the fridge overnight and eat cold without steaming. 

Enjoy while still hot, alongside your favorite dipping sauces.
