Ingredients for Seafood Butter Sauce

- Olive Oil: You can use regular olive oil or vegetable oil for this recipe.
- Onion: Use either yellow or white onion.
- Old Bay Seasoning: It adds great flavor to the sauce with layers of complex flavors. .
- Chicken Broth: We recommend using low-sodium broth to reduce the salt intake.
- Lemon Pepper: Adds freshness and brightness to the sauce.
- Paprika: It adds a fruity and slightly sweet note with a bright color to the sauce. You can also use smoked paprika.
- Cayenne Pepper: It adds some heat to the sauce with a distinct fruity flavor.

Seasoning for Seafood Boil or Crab Sauce
It’s no secret that seasoning is the key to a good seafood boil. First, you’ll need a hearty helping of garlic, sautéed in melted butter.
Be generous with the Old Bay seasoning, the classic Southern mix that’ll give your sauce both flavor and color.
Because we love a spicy seafood boil, we’ll be stirring in cayenne pepper, lemon pepper and red pepper flakes, with the milder taste of paprika to balance things out. Imagine the aroma in your kitchen when it all comes together!
Even Better with These Tips
- If you prefer a milder seafood boil, adjust the amount of cayenne and red pepper that you add in. Even without the extra spice, your meal will be full of flavor thanks to the rest of the herbs and spices.
- Be sure to keep the heat on low to allow your sauce to slowly simmer to perfection.
- Feel free to add more butter if you prefer a richer sauce.
Seafood Boil Sauce vs Bloves Sauce
Bloves sauce is another kind of seafood sauce made popular by the Youtuber of the same name.
It’s similar to Seafood Boil Sauce because they’re both made with butter and garlic as the base, but Bloves sauce also includes Worcestershire sauce, Tabasco sauce and vinegar for a more sophisticated taste.
How to Make Seafood Boil?
Seafood Boil is a delicious, yet simple one-pot meal that’s great for feeding a group. If you’ll be adding potatoes to the mix, you’ll want to put those in first, along with the seasoning and corn.
Next, add in sausage and onions, ensuring they’ve been cut into bite-size pieces. Add crabs and clams next.
Shrimp should be added last, since they cook the fastest. They’ll be ready in about two minutes, so be sure not to overcook them. (See details in the recipe below)
How to Store the Sauce?
This sauce can easily be stored for an encore seafood boil. Pour any leftover sauce into an airtight container and store in the fridge for up to two weeks.
When you’re ready to use it again, just heat it up in a pot and toss in your potatoes, seafood, and other ingredients.
How to Reheat Seafood Boil Sauce
We recommend adding the sauce to a saucepan on the stove over low heat and letting it warm up gradually. If you want to serve it quickly, you can microwave it for about 30 seconds to 1 minute.
Variations
- Sweet and Spicy Seafood Boil Sauce: Adding in some sweet ingredients can take your sauce to the next level. Stir in an extra ½ cup of brown sugar, honey or maple syrup and taste the difference.
- Seafood Cajun Butter Sauce: Simply add cajun seasoning to your sauce. Now you have a rich Cajun butter dipping sauce for your favorite meat, seafood or veggies.
- Louisiana Seafood Boil Sauce: For a classic Louisiana Seafood Boil, be sure to add in bay leaves, fresh ginger and lemon slices.

Hi is their is it ok if we do don’t have old bay seasoning ?

Hi Vida, it’s ok if you don’t add old bay seasoning. But if you have celery salt and paprika, you can add them to your sauce. As celery salt and paprika are two of the main ingredients in Old Bay seasoning.
