Step‑by‑Step Instructions for Cajun Seafood Boil with Spicy Butter Sauce Recipe
Step 1: Boil Base Prep
In a large pot, bring 4-5 quarts of water to a rolling boil over high heat. Stir in Cajun seasoning, minced garlic, bay leaves, lemon slices, and onion. Once the mixture is boiling vigorously, this aromatic broth will serve as the flavor-packed base for your Cajun Seafood Boil with Spicy Butter Sauce.
Step 2: Vegetable Cooking
Add the scrubbed and quartered potatoes and the corn on the cob to the boiling broth. Allow them to cook for approximately 10 minutes, or until the potatoes are fork-tender but still firm. The corn should also be bright yellow and soft when ready, ensuring they soak up all those beautiful Cajun flavors.
Step 3: Add Seafood
After the vegetables are cooked, gently introduce the prawns, crab, and mussels into the pot. Cook for an additional 5-7 minutes until the prawns turn opaque and the mussels open up wide. This is a key step in the Cajun Seafood Boil with Spicy Butter Sauce recipe, ensuring everything is cooked just right for a delightful seafood experience.
Step 4: Butter Sauce Creation
While your seafood cooks, prepare the spicy butter sauce. In a separate pan over medium heat, melt 1 cup of unsalted butter. Add minced garlic, Cajun seasoning, smoked paprika, and chili flakes, stirring continuously for 2-3 minutes until the garlic is fragrant and the mixture begins to bubble slightly. This fragrant blend will elevate your seafood boil.
Step 5: Combine and Serve
Once everything is perfectly cooked, carefully drain the seafood and vegetables, then transfer them to a large serving platter or bowl. Pour the rich Cajun butter sauce over the top and toss gently to ensure all the seafood and veggies are well-coated. Serve immediately, garnished with fresh parsley for a pop of color, making your Cajun Seafood Boil with Spicy Butter Sauce a show-stopping dish.
