How to make Cajun seafood boil
Veggies: Slice onion into thick slices, smash large garlic cloves and set aside.
Crab: Clean crab and set aside.
Shrimp: De-vein and rinse shrimp and set aside
Sausage: Cut sausage into thick slices and set aside.
Potatoes: If using medium or large red or Yukon potatoes cut into quarters otherwise if using 2-bite potatoes or creamer potatoes just wash and set aside.
Corn on the cob: If using fresh corn, remove the husk and cut each ear of corn in half or thirds and set aside. Frozen corn on the cobs works too.
Cajun garlic butter sauce: Melt butter into a sauce pan, add minced garlic and Cajun seasoning, whisk and set aside.
The Boil: Fill a large pot of water about half full, add in sliced onions, smashed garlic cloves, kosher salt, Cajun seasoning, potatoes, corn and sausage and allow the water to come to a gentle boil. When the potatoes are nearly done, add in the crab and cook for 5 to 8 minutes, then add in the shrimp and cook for an additional 2 to 3 minutes then turn off heat.
Using a large slotted spoon, remove all the crab, shrimp, potatoes, and corn from the water and place in a roasting pan. Pour the Cajun garlic butter sauce over the seafood, corn and sausage and gently mix until all is coated. Squeeze fresh lemon juice over the top, and dash of kosher salt and garnish with curly-leaf parsley.
Serve immediately and enjoy.
Tips
- FIRST place potatoes, sausage, corn, sausage and seasoning in pot THEN bring to a gentle boil
- Feel free to use a clean and chemical-free scrub brush to help scrub the hair from the crab
- Use a paring knife to de-vein the shrimp (it's so much easier)
- Prep all ingredients first and have them close by
- You can use shell-on or peeled shrimp (I prefer peeled shrimp with the tail-on mostly for presentation)
- You can use smokey Kielbasa or Andouille sausage (I prefer andouille for its smokey, spicy, garlicky taste)
- You can also add clams, mussels and lobster to your seafood boil
- Freshly squeezed lemon juice is highly recommended
- Large sized shrimp or prawns are best
- Fresh corn on the cob is best
- Although you can use, dungeness crab, snow crab, Jonah crab claws, or king crab legs, I prefer dungeness
- The amount of ingredients I used for this Cajun recipe is for serving a crowd (please feel free to cut the amount of ingredients in half if serving less people)
What to serve with a seafood boil
Cajun seafood boil is the star of the show and can certainly be served on its own; however, if you're looking for the perfect side dish to accompany this dish, I suggest garlic bread as simple as it may sound.

The recipe does not say how to make "cajun seasoning" or "cajun spice mix".
Cree says
Hello - You could purchase your favorite store brand; however, if you'd like to make it from scratch just combine these ingredients:
4 Tbsp granulated garlic powder
4 Tbsp onion powder
4 Tbsp smoked paprika
3 tsp dried thyme
3 tsp dried parsley
3 tsp red pepper flakes
1 tsp cayenne pepper (more or less depending on your level of heat)
I usually make a big batch and store it in an airtight container and place it in my pantry. When I need more, I can make it quickly as I always have those ingredients on hand. I hope this helps.
Please let me know if you have any other questions.
