One of our favorite seafood dishes is crab legs. These crab legs can be prepped and steamed, and served with a mouth watering helping of garlic butter for full bodied flavor! 

Snow crab and snow crab legs in butter sauce are my happy place. I get mine flown in from a place in Alaska. It’s not cheap, but crab meat and steamed snow crab legs are a special occasion around my house. My husband prefers crab cakes. to each his own.

As crab legs are often pre cooked slightly before they are frozen, the best way to cook them up is to steam them. The best thing about cooking crab legs this way is that it only takes a few minutes, and is actually really simple to do.

Crab legs are full of tender, flavorsome and succulent meat that is mouth wateringly good when consumed. Some of the most popular crab leg dishes are served across the world including in Europe, the US, and Canada, with Alaskan king crab legs being the favored option.

When crabs are caught on the fishing boats, they are cooked slightly, and then flash frozen immediately to preserve their freshness and flavor ready for consumption. This is why before you even think about starting the process of cooking or steaming your crab legs, you will need to defrost them first.

Most frozen crab legs will need to be defrosted within a refrigerator, and will take approximately 8 hours to defrost, so you may benefit from taking them out of the freezer and leaving them to defrost in the refrigerator overnight. 

You can also use salty, cold water to help thaw out the frozen crab legs before placing them inside your refrigerator. Once thawed completely, you can begin the process of cooking up your crab legs for a delicious meal!

However, our favorite way to steam crab legs at home is to use a steamer.

The first step is to ensure that the crab legs are completely thawed before cooking. Once this is done, you will need to pour the two cups of water in the steamer and bring it to the boil.

Then, place the crab legs in the steamer basket, and leave them in there until the water is at boiling point.

Once the water has reached boiling point, you will want to place the steamer basket with your crab legs in, and set your steamer timer to 7 minutes. 

You will know that your crab legs are ready by the stunning aroma that will fill the air. However, you can also touch the crab legs to check if they are heated up properly.  If the crab legs are extra hot to the touch, then they will most likely be ready to serve.

Once the crab legs are ready, remove them from the steamer, and top them with a little melted butter or olive oil, and a squeeze of a lemon wedge. 

Whilst cooking crab legs with a steamer is the easiest trick to steam crab legs, you can cook them without a steamer, too. 

Cooking Crabs Legs Without a Steamer

To cook crab legs without a steamer, you can use a large pot with a colander. You will first have to fill the pot with water, filling it up until it is about ⅓ of the way full. Then, you can bring the water to the boil on a high heat.

Whilst your water is beginning to boil, you should place your crab legs inside the colander. When the water has reached boiling point, you must place the colander inside the pot, and cover the pot and colander with a lid to create steam. 

Leave your crab legs to steam for about 10 minutes this way, checking to see if they are cooked by touching the legs after a few minutes. 

Cooking Crabs Legs In the Oven

You may be surprised to find that you can cook crab legs in the oven, too! All you have to do is put water in a pan and place it on a rack in your oven. Then, simply preheat your oven and allow the water to boil.

Once this is done, you can place your crab legs in the pan, covered with a wet towel, and turn the oven on to bake mode for the best results. 

For this method, you will have to keep a close watch on the towel to ensure that it does not dry up at all, and allow the crab legs to steam for about 15 minutes. 

Our Top Tip

Our top tip is to serve up your crab legs with a little melted butter, and some garlic for a delicious garlic sauce to go on top!
