Ingredients

Scale
  • 5 pounds live crawfish, fresh and cleaned
  • 1.5 pounds small red or new potatoes, whole or halved
  • 4 ears corn on the cob, cut into thirds
  • 1/2 cup Cajun boil seasoning (such as Zatarain’s or Old Bay)
  • 6 cloves garlic, smashed
  • 1 large onion, quartered
  • 2 lemons, halved
  • 34 bay leaves
  • 2 tablespoons hot sauce (optional)
  • 2 tablespoons salt, to taste
  • 6 quarts water
  • 4 tablespoons melted butter (for serving)

Instructions

  1. Rinse live crawfish thoroughly in cool water, discarding any dead ones (about 10 minutes).
  2. Fill a large pot with 6 quarts of water. Add Cajun seasoning, smashed garlic, quartered onion, bay leaves, salt, and halved lemons. Stir to dissolve seasoning and bring to a rolling boil over high heat (about 15 minutes).
  3. Add potatoes to boiling water and cook for 15 minutes or until almost tender when pierced with a fork.
  4. Add corn pieces and cook for another 5 minutes until bright and slightly tender.
  5. Add live crawfish carefully into the pot, stir gently to submerge, cover and cook for 5–7 minutes until crawfish turn bright red.
  6. Turn off heat and let crawfish soak in seasoned water for 15–20 minutes to absorb flavors.
  7. Drain everything well using a slotted spoon or pot basket. Spread crawfish, corn, and potatoes on a newspaper-covered table for serving.
  8. Serve with melted butter and lemon wedges for dipping and brightening each bite.

Notes

Keep an eye on potatoes to avoid undercooking. Do not overcook crawfish to prevent rubbery texture. The soaking step after boiling is essential for deep flavor penetration. Adjust spice levels by adding more or less Cajun seasoning or hot sauce. For gluten-free, verify seasoning ingredients or make your own blend. Fresh crawfish preferred over frozen for best flavor. Use outdoor burner for safety and ventilation.
