Ingredients
- 1 pound (4 sticks) unsalted butter
- 8 cloves garlic, minced
- 2 tablespoons Old Bay seasoning
- 1 tablespoon Cajun seasoning
- Zest of 2 fresh lemons
- 3 tablespoons fresh lemon juice
- 1 teaspoon red pepper flakes (adjust to taste)
- 1 teaspoon smoked paprika
- ½ teaspoon cayenne pepper
- ½ teaspoon black pepper
- ½ teaspoon sea salt
- 2 tablespoons fresh parsley, finely chopped
- 1 tablespoon fresh dill, finely chopped
- ½ teaspoon Worcestershire sauce
- Pinch of garlic powder
Instructions
- Cut your unsalted butter into cubes and allow it to soften slightly at room temperature for about 5 minutes – this helps it melt more evenly and incorporate all the flavors beautifully.
- In a large saucepan over medium heat, add the butter cubes and allow them to melt slowly, about 3-4 minutes, stirring occasionally so they melt evenly without browning.
- Once the butter is completely melted, reduce the heat to medium-low and add your minced garlic, stirring constantly for about 1-2 minutes until the garlic becomes fragrant and slightly softened but not browned.
- Sprinkle in the Old Bay seasoning, Cajun seasoning, smoked paprika, cayenne pepper, and red pepper flakes, stirring constantly to distribute all the spices evenly throughout the butter.
- Add the sea salt, black pepper, and garlic powder, continuing to stir so that every spice is fully incorporated and there are no clumps.
- Pour in the fresh lemon juice slowly while stirring – the sauce will bubble slightly, which is completely normal – and add the fresh lemon zest, stirring for about 1 minute.
- Add the Worcestershire sauce and stir well, making sure everything is fully combined and the sauce has a beautiful golden color.
- Reduce heat to low and add the chopped fresh parsley and fresh dill, stirring gently for about 30 seconds just to combine – don’t cook it too long or you’ll lose the fresh herb flavor.
- Taste your sauce and adjust seasonings as needed – if you want it spicier, add more red pepper flakes or cayenne; if you want more lemon flavor, add a bit more lemon juice; if you want it more garlicky, add minced garlic and cook for another minute.
- Keep the sauce warm over very low heat, stirring occasionally, until you’re ready to serve with your boiled seafood – the sauce should never come to a boil or brown, as that will change its flavor profile.
Pro Tips
Don’t skip the fresh herbs at the end – they add brightness and freshness that takes this sauce from good to absolutely incredible.
If you prefer a less spicy version, start with half the cayenne pepper and red pepper flakes and add more gradually until you reach your desired heat level.
This sauce pairs beautifully with shrimp, crab, lobster, mussels, and clams – really any seafood you’re boiling.
Make sure to use unsalted butter so you have complete control over the salt content of your sauce.
If the sauce breaks or becomes greasy, simply remove it from heat and let it rest for a few minutes, then whisk in a tablespoon of lemon juice or water to help it come back together.
Leftover sauce can be stored in an airtight container in the refrigerator for up to one week – simply reheat gently over low heat before serving.
For a richer sauce, you can add a splash of heavy cream, but this is entirely optional and not necessary for a delicious result.
The quality of your butter really matters here – use a good quality unsalted butter for the best flavor and richness.
You can make this sauce in advance (up to 2 days ahead) and simply reheat it gently when ready to serve.
If you want to add more protein flavor, try adding a tablespoon of seafood stock or clam juice to the sauce.
This sauce is also fantastic as a dipping sauce for crusty bread, steamed vegetables, or even as a finishing sauce for pasta.
