How to Make Garlicky Seafood Boil Sauce with Butter
Step 1: Melt the Butter and Olive Oil
Grab a medium saucepan and set it over medium heat. Add the unsalted butter and olive oil, letting them melt together until the mixture is smooth and glossy. The olive oil helps prevent the butter from burning, so you’ll get a perfectly silky base for your Garlicky Seafood Boil Sauce with Butter.
Step 2: Sauté the Garlic
Toss in the minced garlic and sauté for just 1 to 2 minutes. You want the garlic to become fragrant and slightly golden, but not browned—this keeps the sauce sweet and mellow, not bitter. The kitchen aroma at this point is pure magic!
Step 3: Add the Spices and Herbs
Now, sprinkle in the onion powder, smoked paprika, cayenne pepper, lemon pepper seasoning, Old Bay, thyme, and oregano. Stir constantly for another 1 to 2 minutes so the spices bloom and infuse the butter with their flavors. This is where the sauce takes on that deep, Cajun-inspired complexity.
Step 4: Add Lemon Juice and Hot Sauce
Pour in the fresh lemon juice and, if you’re feeling adventurous, a splash of your favorite hot sauce. Give everything a good stir, then season with salt and black pepper to taste. The lemon brightens the whole sauce, balancing the richness and spice.
Step 5: Simmer and Finish
Let the Garlicky Seafood Boil Sauce with Butter simmer on low for 3 to 5 minutes. This gentle bubbling helps all the flavors meld together beautifully. Just before serving, stir in the chopped fresh parsley for a burst of color and freshness. Serve the sauce warm, either poured over your seafood boil or as a dreamy dipping sauce on the side.
How to Serve Garlicky Seafood Boil Sauce with Butter

Garnishes

Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
If you find yourself with leftover Garlicky Seafood Boil Sauce with Butter (lucky you!), let it cool to room temperature before transferring it to an airtight container. It will keep fresh in the refrigerator for up to a week, ready to brighten up any meal in a flash.
Freezing
This sauce freezes surprisingly well! Pour cooled sauce into a freezer-safe container or portion it into an ice cube tray for easy, single-serve amounts. Thaw overnight in the fridge before reheating and giving it a good stir to restore its silky texture.
Reheating
To reheat, simply warm the sauce gently in a saucepan over low heat, stirring often. If it seems a little thick, add a splash of seafood broth or water to loosen it up. Avoid microwaving on high, as this can cause the butter to separate.

How can I thin out the sauce if it gets too thick?
If your Garlicky Seafood Boil Sauce with Butter thickens up, simply stir in a splash of seafood broth, water, or even a little extra lemon juice until you reach the perfect consistency for dipping or drizzling.
