Step-by-Step Guide to Make Seafood Cajun Boil
Step 1: Gather Your Ingredients
Prepare shrimp, crab legs, mussels, sausage, corn, potatoes, butter, garlic, Cajun seasoning, lemon, and parsley. Wash all seafood properly and cut the corn into smaller pieces for easier cooking.
Step 2: Boil the Potatoes and Corn
Fill a large pot with water and bring it to a boil. Add the potatoes first because they take longer to cook. After about 10 minutes, add the corn and let everything cook until slightly tender.
Step 3: Add Sausage and Seafood
Place the sliced sausage into the pot and cook for 5 minutes. Next, add the crab legs, shrimp, and mussels. Cook until the shrimp turns pink and the mussels open completely.
Step 4: Prepare the Cajun Butter Sauce
In a separate pan, melt butter and mix in minced garlic, Cajun seasoning, lemon juice, and a little paprika. Stir well until the sauce becomes rich and fragrant.
Step 5: Combine and Serve
Drain the seafood mixture carefully and place it in a large serving tray or bowl. Pour the Cajun butter sauce over everything and toss gently to coat evenly. Garnish with chopped parsley and lemon slices before serving hot.
