How to Make Crawfish Boil
- Purge the crawfish: Place the rinsed crawfish in a large container filled with cold water and ½ cup kosher salt. Stir and let them sit for 10 minutes. Drain and rinse well. Repeat this process if needed until the water runs clear.
- Prepare the boil: In a large stockpot, add water, the remaining kosher salt, Cajun seasoning, garlic, lemons, and bay leaves. Bring the mixture to a rolling boil.
- Cook the potatoes: Add the potatoes to the boiling water and cook for about 10 minutes, or until they begin to soften.
- Add corn and sausage: Add corn and sausage to the pot and cook for another 5 minutes.
- Cook the crawfish: Add the crawfish to the pot, stir gently, and cook for 5 to 7 minutes until the crawfish turn bright red.
- Let soak: Turn off the heat and let everything soak in the seasoned water for 15 to 20 minutes to allow the flavors to develop.
- Drain and serve: Drain the contents and spread them out on a large table or serving tray. Serve hot with lemon wedges and hot sauce if you like.
Tips & Variations for Crawfish Boil
Tips
- Make sure to purge the crawfish well to remove any dirt or grit for the best flavor.
- Use fresh, live crawfish whenever possible for the best taste and texture.
- Avoid overcooking the crawfish since they cook fast and can become tough if boiled too long.
- Allowing the boil to soak after cooking helps the flavors deepen and meld together.
Variations
- Add other types of seafood like shrimp or crab to create a mixed seafood boil.
- Include extra vegetables such as mushrooms or onions for more variety.
- Experiment with different spice blends to adjust the heat and flavor to your liking.
- For a milder version, simply reduce the amount of Cajun seasoning used.
