How Long to Boil or Steam Blue Crabs

The Times That Matter at the Pot

Cooking blue crabs is not an exact science, but the ranges are dependable. For a typical dozen, plan on about 20 minutes at a boil and 20 to 30 minutes over steam. The visual check matters more than the clock: crabs are done when no blue remains and the shells have turned a bright orange-red all over.

Boiling Blue Crabs

  • Time: around 20 minutes for a dozen.
  • Setup: only a few inches of water in the stockpot, seasoned if you like, and do not overcrowd the pot.
  • Done when: shells are bright orange with no blue left anywhere.

Steaming Blue Crabs

  • Time: 20 to 30 minutes for a dozen, a little longer for the largest grades.
  • Setup: a rack or basket above two inches of boiling water, crabs layered with seasoning, lid on tight.
  • Done when: the same color test applies; steam until every shell has turned.

Steaming is the Maryland tradition, and for good reason: the meat cooks in its own moisture instead of taking on water, and the seasoning stays put on the shell where a picker's fingers find it. Which method wins is a longer conversation; our guide to steaming, baking, and boiling crab makes the full comparison.

Before and After the Pot

Whole crabs should go into the pot lively or freshly steamed, never questionable. If you ordered from us, your crabs arrive already steamed to order and only need reheating. Set them above an inch or two of boiling water (a cup of beer in the pot is a classic Maryland addition), cover, and give them no more than eight minutes. An oven works too: about ten minutes at 375°F brings a steamed crab back to temperature without drying the meat. Refrigerated steamed crabs should be eaten within 2 to 3 days.

Once the crabs are cooked and the table is covered in paper, the real work begins. Our step-by-step eating guide takes a first-timer from whole crab to clean shell.

Frequently Asked Questions

Do bigger crabs need more time?

Yes. A dozen small crabs sit at the short end of the range, while heavyweight grades need the full time. When cooking mixed sizes, judge by the largest crabs in the pot.

Can I overcook blue crabs?

You can. Meat that cooks far past done turns stringy and loses its sweetness, so pull the crabs once the color test passes rather than adding minutes for safety.

Should the crabs be layered with seasoning?

For steaming, yes: coat each layer as it goes into the pot. Our steamed crabs ship already seasoned, or plain if you prefer to season your own.
