What You’ll Need

• Live blue crabs – allow about 3-5 crabs per person
• Large stock pot – at least 6 quarts capacity
• Slotted spoon or tongs for handling the crabs
• Salt – 1/2 cup per gallon of water
• Crab boil seasoning – Old Bay, J.O. #2, or other
• Whole lemons, halved
• Melted butter for dipping
• Smaller pots or buckets for pre-boil and ice baths
• Newspapers or tablecloth to cover your workspace
• Crab mallet and pick for cracking the shells
• Bibs, wet wipes, and empty bowl for shells

Step 1 – Prepare the Crabs

Before boiling, the crabs need to be washed thoroughly and placed in an ice bath to sedate them. This makes it easier to handle them once boiling.

Fill a sink or bucket with cold water and ice, Rinse each crab individually under cold running water Then place them in the ice bath for at least 10 minutes until they are still and sedated,

Step 2 – Season the Boiling Water

Fill your large stock pot about halfway with cold water. Add 1/2 cup of salt for each gallon of water, which helps season the meat and raises the water’s boiling temperature.

Next add your choice of crab boil seasoning – at least 2-3 tablespoons per gallon. Crab boil contains spices like mustard seed, coriander, bay leaves, and red pepper that infuse the crabs with flavor.

Add the juice of 1-2 halved lemons to the pot for some bright, tangy flavor.

Step 3 – Bring the Water to a Boil

Place the pot over high heat and allow the salted, seasoned water to come to a rolling boil. The large bubbles should be steadily breaking the surface of the water.

Once boiling, carefully lower the chilled crabs into the pot using tongs or a slotted spoon. Work in batches if needed to avoid overcrowding the pot.

Let the pot return to a boil before covering and starting your timer.

Step 4 – Cook the Crabs

Once the crabs are added, keep the water at a rolling boil as they cook. Cook for 12-18 minutes if boiling smaller crabs, and 18-25 minutes for larger crabs.

Test for doneness after 12 minutes. Use tongs to pull a crab from the pot and pull off a leg, cracking it open to inspect the meat. It should be opaque and firm but still juicy, not mushy.

Pop the crab back in the pot if it needs more time. Don’t leave the lid off for longer than necessary or it will lengthen the cooking time.

Step 5 – Cool the Crabs

Once the crabs are cooked through, use a slotted spoon or tongs to transfer them to another ice bath. Let them chill for about 10 minutes to stop the cooking process.

Then drain the chilled crabs in a colander before stacking them on a platter.

Step 6 – Pick, Crack, and Feast!

Now it’s time for the fun part – picking out all that sweet crab meat! Cover your table with newspaper or a plastic cloth to catch any drips and flies away.

Provide each guest with a crab mallet, pick, bib, and wet wipes. Put out bowls for empty shells and melted butter for dipping the meat.

Start cracking by removing the top shell, apron, gills, and mouth parts. Break the body and claw shells by hitting the seams with the mallet. Then use the pick to pull out the lump crab meat. Dip in melted butter and enjoy!

Savor the delicious fruits of your labor as you pick through pile after pile of bright red crab. Just be ready for a deliciously messy feast!
