🥗 Ingredients
The Crabs
- 1 bushel Live Blue Crabs (approximately 4-5 dozen, rinsed thoroughly with cold water)
The Boil Base
- 5 gallons Water (enough to fill a large stockpot halfway)
- 1 bag Dry Crab Boil Seasoning (16oz bag, such as Zatarain's or Louisiana Fish Fry brand)
- 4 ounces Liquid Shrimp & Crab Boil (concentrated spicy extract)
- 1 cup Kosher Salt (adjust based on seasoning brand salt content)
- 4 pieces Lemons (halved and squeezed)
- 3 heads Garlic (halved crosswise to expose cloves)
- 3 large Yellow Onions (peeled and quartered)
- 5 pieces Bay Leaves (dried)
The Fixings
- 1 pound Andouille Sausage (cut into 2-inch chunks)
- 2 pounds Red Bliss Potatoes (small, whole)
- 6 ears Sweet Corn (husked and snapped in half)
- 2 sticks Unsalted Butter (melted for dipping)
👨🍳 Instructions
-
1
Rinse the live crabs thoroughly in their basket or a large tub using a garden hose with cool water to remove any mud or debris. Discard any crabs that are not moving.
-
2
Fill a 30-to-40-quart outdoor boiling pot with approximately 5 gallons of water. Place it over a high-output propane burner.
-
3
Add the dry crab boil seasoning, liquid boil concentrate, salt, halved lemons (squeeze the juice in first, then drop the rinds in), garlic heads, onions, and bay leaves.
-
4
Cover the pot and bring the seasoned water to a rolling, vigorous boil. Let the aromatics boil for 10-15 minutes to 'season the water' before adding any food.
-
5
Add the whole red potatoes to the pot. Cover and cook for 10 minutes, as they take the longest to soften.
-
6
Add the Andouille sausage chunks to the boiling water and continue to boil for another 5 minutes.
-
7
Carefully add the live blue crabs into the boiling water using tongs. Ensure they are fully submerged. The water will likely stop boiling; cover the pot and wait for it to return to a boil.
-
8
Once the water returns to a boil, set a timer for 10-12 minutes. The crabs should turn a bright, vibrant orange-red color.
-
9
Add the corn cob halves during the last 5 minutes of the crab's boiling time.
-
10
Turn off the heat entirely. This is the most important step: let the crabs soak. Pour a half-gallon of ice or cool water over the top to help the crabs sink and absorb the spicy broth.
-
11
Allow the crabs to soak for 15-20 minutes. Taste a potato at 15 minutes; if it's spicy enough for you, the crabs are ready. If you want more heat, soak for another 10 minutes.
-
12
Lift the strainer basket out of the pot, letting the excess liquid drain away. Dump the contents onto a table covered in several layers of newspaper or brown butcher paper.
-
13
Serve immediately with bowls of melted butter and plenty of napkins.
💡 Chef's Tips
Always use live crabs; never boil a dead blue crab as the meat breaks down and becomes unsafe very quickly. To make the crabs easier to peel, the 'cold shock' during the soak step helps the meat pull away from the shell. If you prefer less heat, omit the liquid boil concentrate and stick only to the dry seasoning bags. Keep a bowl of white vinegar or lemon water on the table to help clean the spicy oils off your hands after eating. Don't forget to 'pinch the tail and suck the head' of any crawfish if you decide to throw a few pounds of those into the same pot!
🍽️ Serving Suggestions
Serve with ice-cold local Abita beer or a crisp, dry Riesling to cut through the spice. A side of creamy southern coleslaw provides a refreshing, cooling contrast to the heat. Provide small ramekins of 'Cajun Butter' (melted butter mixed with a teaspoon of the dry boil seasoning). Keep plenty of extra lemon wedges on the table for those who like an extra hit of acidity. Finish the meal with a classic lemon icebox pie or bread pudding to soothe the palate.
