Popular Crawfish Boil Seasonings You Can Buy
Louisiana grocery stores offer a wide variety of excellent crawfish boil seasonings, each with its own blend of spices and heat level. Most brands are available in both powdered and liquid boil concentrates, making it easy to customize the flavor of your crawfish boil. Many Louisiana cooks even combine different brands to create their own signature seasoning blend.
How to Clean Crawfish
Start by rinsing the crawfish thoroughly with clean water. Stir them around and drain several times to remove mud and debris. Remove any dead crawfish. Keep flushing them with fresh water until your water is clean.
Contrary to popular belief, crawfish do not need a salt purge. Instead, continue rinsing with fresh water until it runs mostly clear. Then drain completely before cooking.
How to Boil Crawfish Like a Cajun
Season the Water
Fill a large crawfish pot about halfway with water. Next, add the powdered boil, liquid boil, hot sauce, and cayenne pepper if desired.
Bring the pot to a rolling boil before adding any ingredients.
Cook the Vegetables
Add the potatoes first and boil them for 5–7 minutes.
Then add the lemons, onions, and garlic. Continue boiling for another 3 minutes so the vegetables can begin releasing their flavor into the water.
Add the Crawfish
Bring the pot back to a hard boil if needed. Carefully add the crawfish and stir well.
Once the water returns to a boil, cook the crawfish for 3–5 minutes.
The Soak
Add the corn and immediately turn off the heat.
Now comes the most important step. Allow the crawfish to soak for 20–30 minutes while stirring occasionally. Most of the seasoning enters the crawfish during the soak, not during the boil.
Taste a crawfish every few minutes until the spice level reaches your preference.
For faster seasoning absorption, spray the outside of the pot with cold water or add a small bag of ice after turning off the burner. The rapid temperature drop helps the crawfish absorb liquid and sink to the bottom.
If using ice, remember it slightly dilutes the boil. Many Louisiana cooks compensate by starting with a little extra seasoning.
Dump and Serve
Drain the pot and dump everything onto a table covered with newspaper or butcher paper.
Then gather around, grab a cold drink, and enjoy one of Louisiana’s greatest traditions.
How Crawfish Should Taste
Properly boiled crawfish should be:
- Spicy but balanced
- Easy to peel
- Juicy inside the tail
- Loaded with flavor
- Well seasoned throughout
If your crawfish taste bland, they likely need more soak time. If they’re dry, they may have cooked too long.
Cooling the Crawfish After the Boil (optional)
Once the crawfish have finished boiling, you can stop the cooking process before they become overcooked. Many people cool the pot by hosing the outside of the pot with cool water from a garden hose, while others prefer using ice. Both methods work, but adding large amounts of ice can dilute the seasoning and reduce the bold Louisiana flavor you’ve worked to build. If you use ice, keep the amount to a minimum or increase your seasoning to compensate. Cooling with fresh water gives you more control over the temperature while helping the crawfish soak up the seasoned liquid without watering it down.
Optional Ingredients to Add to Your Crawfish Boil
One of the best parts of a Louisiana crawfish boil is customizing it with extra ingredients. While potatoes, corn, onions, garlic, lemons, and smoked sausage are traditional favorites, plenty of other foods soak up the seasoned boil and add variety to the table. Popular additions include mushrooms, Brussels sprouts, artichokes, cauliflower, asparagus, green beans, pineapple, oranges, sweet potatoes, and even whole heads of cabbage. Some people also add shrimp near the end of the boil for an extra seafood option. Don’t be afraid to experiment with your favorites. Just remember that each ingredient cooks at a different rate, so add them in stages to keep everything perfectly cooked.
