Ingredients Equipment Method Notes

Ingredients
  

  • 1 cup unsalted butter (2 sticks)
  • 8-10 cloves garlic minced
  • 1/4 cup fresh lemon juice
  • 2 tablespoons Old Bay Seasoning
  • 1 tablespoon paprika
  • 2 teaspoons Cajun seasoning or more, to taste
  • 1 teaspoon dried thyme
  • 1/2 teaspoon cayenne pepper or more, for extra heat
  • salt to taste
  • freshly ground black pepper to taste
  • 2 tablespoons fresh parsley chopped, for garnish (optional)

Equipment

  • Medium Saucepan

Method
 

  1. In a medium saucepan, melt the unsalted butter over medium-low heat. Avoid letting the butter brown too quickly; we want it gently melted.
    1 cup unsalted butter
  2. Add the minced garlic to the melted butter. Sauté for about 1-2 minutes, stirring constantly, until the garlic is fragrant. Be careful not to burn the garlic, as this will make it bitter. You want it softened and aromatic, not crispy.
    8-10 cloves garlic
  3. Stir in the Old Bay Seasoning, paprika, Cajun seasoning, dried thyme, and cayenne pepper. Cook for another minute, stirring continuously, to bloom the spices and release their full flavor into the butter. This step is crucial for deepening the aroma and taste of the sauce.
    2 tablespoons Old Bay Seasoning, 1 tablespoon paprika, 2 teaspoons Cajun seasoning, 1 teaspoon dried thyme, 1/2 teaspoon cayenne pepper
  4. Pour in the fresh lemon juice. The acidity of the lemon juice will cut through the richness of the butter and brighten the overall flavor profile of the sauce. Stir well to combine.

  5. Season the sauce with salt and freshly ground black pepper to your liking. Remember that Old Bay and Cajun seasonings already contain salt, so taste before adding too much.

  6. Let the sauce simmer gently for an additional 2-3 minutes, allowing the flavors to meld and the sauce to slightly thicken. You can adjust the consistency by adding a touch more butter if it becomes too thick, or by simmering a bit longer if you prefer it thicker.
  7. Remove the saucepan from the heat. If using, stir in the chopped fresh parsley for a burst of vibrant color and fresh herbaceousness. Serve the Cajun Seafood Boil Garlic Butter Sauce warm, generously drizzled over your cooked seafood.

Notes

This sauce can be stored in the refrigerator for up to 3-4 days in an airtight container. Reheat gently on the stovetop or in the microwave. It can also be frozen for 1-2 months, though whisking may be needed after thawing to recombine separated butter.
