  • Live crab(s) – Dungeness, blue crab, etc.
  • Water
  • Sea salt or kosher salt
  • Crab seasoning: bay leaves, peppercorns, Old Bay, etc. (optional)
  • Melted butter for serving
  • Lemon wedges for serving

sourcing Live Crabs

The first step is tracking down a source for quality live crabs. Here are some options:

  • Local fishermen often sell freshly caught live crabs on piers or docks. This ensures peak freshness.

  • Asian and international markets frequently stock live crab varieties.

  • Some specialty seafood shops sell live local crabs in season.

  • You may be able to order live crabs online and have them shipped overnight.

Look for crabs that are very lively, with all legs intact. Make sure the shell isn’t cracked. Plan on at least one 1-1.5 pound crab per person.

Preparing to Cook

Once you get your crabs home, you’ll need to prep for cooking:

  • Keep them cold – Store crabs in a cooler or in the refrigerator until ready to cook. Keeping them chilled slows their metabolism.

  • Give them a rinse – Run each crab under cold water to clean the shell.

  • Choose your pot – Select the largest stockpot you have – you want the crabs to have plenty of room to simmer.

  • Fill with water & salt – Fill the pot about 2/3 full with cold water. Salt it generously – it should taste like seawater.

  • Add seasonings (optional) – For flavor, you can add crab boil seasoning, bay leaves, peppercorns, lemon, and/or Old Bay.

  • Chill the crabs – Before cooking, place the live crabs in the freezer for 15-20 minutes. This makes them docile for easier handling.

Cooking the Crabs

Once your crabs are chilled and your pot is prepped, it’s go time! Follow these steps:

  • Bring the salted water to a rolling boil.

  • Use tongs to carefully place each crab upside down/legs down into the boiling water. Give them ample room.

  • Cook for 18-20 minutes from the time the water returns to a boil. The shells will turn bright orange when done.

  • Use tongs to transfer the cooked crabs to a large bowl filled with ice water. This stops the cooking process.

Cleaning the Cooked Crabs

Cleaning cooked crab takes a little time and work, but it’s incredibly rewarding! Here is a step-by-step guide:

  • Twist off the legs: Give them a firm twist and they should release cleanly. Set legs aside.
  • Flip crab over: The underside of the crab should now be facing up.
  • Remove the apron: Lift away and discard the small triangular flap.
  • Open the shell: In the center there is a semi-circular marking. Insert thumbs on either side and crack the shell open.
  • Remove gills & viscera: Pull out the spongy gills on either side of the cavity. Scoop out the yellowish “crab butter” and rinse clean.
  • Divide the body: Crack the body in half down the centerline.
  • Remove meat: Pick the meat out of each section, being sure to get the leg meat.
