Cooking Blue Crab
How to Handle & Prepare Live Atlantic Blue Crabs

Catching and cooking blue crabs, fresh and feisty from our Cape Cod waters, is one of our family's favorite ways to have a simple, delicious summer meal!

And talk about inexpensive ... Atlantic blue crabs are free for the catching on Cape Cod.

All you'll need for your own yummy crab-fest is some basic crabbing equipment, a little crab-catching talent, and a stove or campfire where you can boil up a big pot of water.

Blue crabs are super-simple to prepare. In about 15 minutes, they go from pot to plate. Couldn't be easier!

Handling Live Crabs

There's only one thing about cooking blue crab that can pose a bit of a challenge. That's moving the little devils from their storage container into the pot, while their claws are trying to fend you off.

Rule #1 of Handling a Blue Crab:
Keep your fingers away from theirs!

A blue crab's claws are strong. They're sharp, too. And crabs are incredibly tenacious. Once they latch on, they're not quick to let go.

Thankfully, that's not my thumb in the clutches of that crab claw.

I learned years ago (yes, through trial and very painful error!) that the safest way to handle a live blue crab is from a distance - with a set of long-handled barbecue tongs.

Wieldling my tongs, I grab the crab from behind, top and bottom of the shell, claws pointing away from me. Then I'm the boss!

Preparing Your Blue Crabs for the Pot

Other than rinsing them off, there's not much else you need to do.

If you've purchased your blue claw crabs from a seafood market, they should be nice and clean already.

If you've done it the sporting way and caught your own ...

Just give them a good rinse with your garden hose or kitchen sink sprayer. That's usually enough to remove any lingering seaweed or gunk.

You can go the extra step and use a scrub brush on their shells, if you'd like. I don't usually bother doing that, but it's up to you!

Cooking Blue Crabs

When it comes to cooking fresh-caught blue crabs, I'm definitely a purist.

Nothing goes into our cooking pot except water and the live crabs.

Some folks like to add other stuff to the pot - a little vinegar, a cup of beer, or maybe some "crab boil" spices like Old Bay Seasoning.

Not in my kitchen - no way!

The taste of blue crab meat is sooooo sweet just as it is. I can't imagine why anyone would want to alter that flavor!

Here's my tried-and-true method for cooking blue crab:

  • Put an couple inches of water into a big, sturdy pot. Cover the pot, put it on the stove or over a hot campfire, and bring the water to a rolling boil.

  • When the water is boiling, drop your crabs into the pot. Be sure not to pack them in too tightly.

  • Put the lid back on the pot, and continue to boil on high heat for about 10 minutes.

  • Lift the lid and check on your crabs. When the shells have turned bright orange, your crabs are done.

Spread newspaper across your table for easy clean up, melt some butter for dipping, and enjoy!

Tips for Storing and Cooking Blue Crabs

How to Store Your Live Crabs

Not planning on cooking your blue crab right away?

It's important to store them properly, so they'll be fit to eat when you're ready.

Our method is to put them in a lightly dampened paper bag, and stick them in the refrigerator.

No room in the fridge? Any cool, shady location will do. Keep your crabs cool and damp, and they should be just fine for a few hours, overnight, and maybe even for a day or two.

  • Important: Please don't leave your live blue crabs submerged in water. In no time flat they'll breathe all the oxygen out of the water, and they won't be live crabs for very long.When a crab dies, its meat begins to "go bad" pretty quickly. So treat them right, keep them alive, and throw any dead ones away. It's not worth risking illness.


Putting Your Crabs to "Sleep" Before Steaming

I'm a total woosie when it comes to putting live crabs, live lobsters, or live anything, into a pot of boiling water. That's why my hubby usually gets to do the job, while I hide out in another room until the dastardly deed is done.

On those rare occasions when I have to pot 'em up myself, I prefer to put my live crabs "to sleep" before dropping them in the cooker.


A few minutes in a bowl of ice water puts live crabs into a dormant state, making their ultimate demise a bit less harrowing for all involved.
