A rich, buttery, and spicy Seafood Boil Sauce Recipe that perfectly coats shrimp, crab, and crawfish with deep Cajun flavors and aromatics.

  • Total Time: 25 minutes
  • Yield: 8 servings

Ingredients

2 cups (4 sticks) unsalted butter
1 large onion, very finely diced
10 cloves garlic, minced
3 tablespoons Old Bay seasoning
1 tablespoon smoked paprika
1 tablespoon lemon pepper
1 tablespoon onion powder
1 tablespoon garlic powder
1 tablespoon cayenne pepper (adjust for heat)
2 tablespoons Worcestershire sauce
2 tablespoons hot sauce (like Frank's or Louisiana)
Juice of 1 large lemon
1 tablespoon brown sugar (optional)

Instructions

Step 1: Place a large saucepan over medium-low heat and add the butter. Allow it to melt completely without browning.
Step 2: Add the finely diced onions to the melted butter and sauté for 5-7 minutes until they are soft and translucent.
Step 3: Stir in the minced garlic and cook for an additional 90 seconds until fragrant, being careful not to let it burn.
Step 4: Add the Old Bay, smoked paprika, lemon pepper, onion powder, garlic powder, and cayenne pepper. Whisk well to combine and let the spices bloom in the butter for 2 minutes.
Step 5: Stir in the Worcestershire sauce, hot sauce, lemon juice, and brown sugar (if using). Reduce heat to low and simmer for 10 minutes to allow the flavors of the Seafood Boil Sauce Recipe to meld.
Step 6: Serve immediately by pouring over your seafood boil or as a dipping sauce on the side.

Notes

Store any leftover sauce in an airtight container in the fridge for up to 1 week. Reheat gently over low heat to prevent the butter from separating.
