This sauce is a delectable mixture of ingredients used to season and add flavor to seafood dishes, usually those that are boiled, baked, or steamed. It brightens up the flavor shrimp, crawfish, crab, lobster, and pretty much any seafood. It can be used as a dipping sauce or as a marinade for grilled or smoked meats.
It pairs wonderfully with my Seafood Boil in a Bag recipe.

Frequently Asked Questions and Recipe Pro Tips
Use real butter for the best flavor. Salted or unsalted both work, just adjust your salt at the end.
Butter brings that rich, silky flavor that makes seafood taste even more luxurious. It also helps boost the natural sweetness in the seafood so nothing tastes flat.
Lemon adds brightness and acidity to cut through the richness. It balances everything out and brings that fresh, clean flavor seafood loves.
Garlic steps in for depth and intensity. It’s bold enough to stand next to delicate seafood without taking over, and it rounds out the sauce so it doesn’t taste one-note.
You can add your favorite hot sauce or cayenne pepper to make it spicy.
Yes. It actually gets better as it sits because the spices bloom and the garlic mellows. Make it up to 2–3 days in advance and warm it gently before serving.
Cajun or Creole seasoning, paprika, garlic, onion, lemon, and Old Bay are the usual suspects. They’re bold, savory, and meant for seafood.
You can freeze leftover sauce for up to 3 months. Use an airtight container or a freezer bag and make sure to press out all the air before sealing it. Thaw in the fridge overnight and follow the reheat steps noted above.
Don’t blast it with high heat. Simmer low and slow so the butter emulsifies instead of breaking. Stirring helps too.
Fresh is best. Bottled can make the sauce taste flat or metallic. If fresh lemons are around, use them.
Leftover sauce can be stored in an airtight container in the refrigerator for up to 3 to 5 days.
To reheat it, you can warm it in a saucepan on low heat, stirring occasionally. You can use the microwave. Stick to short bursts of time (I like to check in every 15 seconds) and stir in between to ensure that it is heated evenly. To keep the sauce from separating, it’s best to avoid boiling or overheating it.
If you want it thicker, let it simmer longer or add a little more butter. No flour needed.

Brandi, After you make this sauce can you sauté shrimp or any other fish in the sauce? A small amount in a skillet? Thank you.
