How to Make Seafood Boil Sauce Recipe

Step 1: Melt the Butter

Begin by melting the unsalted butter in a saucepan over medium heat until it’s completely smooth and starting to bubble gently. This ensures a creamy, velvety base that will carry all the spices evenly throughout the sauce.

Step 2: Add the Broth

Slowly pour in the chicken broth while stirring continuously. This not only lightens the texture slightly but also creates a smooth sauce base that perfectly balances the richness of the butter.

Step 3: Season the Sauce

Next, add the Cajun seasoning, Old Bay, smoked paprika, and black pepper. Stir these in thoroughly so the spices bloom in the warm butter and broth mixture, releasing their incredible flavors and aromas.

Step 4: Add Heat

Incorporate the cayenne pepper, red pepper flakes, and hot sauce to bring the right amount of spiciness. Let the sauce simmer gently for 1 to 2 minutes, allowing all the heat elements to meld beautifully while deepening the flavor.

Step 5: Finish with Lemon

Finally, stir in the fresh lemon juice. This vital step adds brightness and acidity that balances the richness and spice, creating a perfectly rounded sauce. Let it simmer for another minute before removing from heat.
