In fact, I have had this burning desire to bottle it for y'all! Feel free to let me know in the comments how you feel about that. That's a whole different subject though.
It is so delicious, I decided to make a whole separate post dedicated to it! Actually, there were so many questions (like HUNDREDS), regarding the process. Therefore, a separate post is deemed necessary at this point!
I’ve had seafood boil before at family’s houses and restaurants but this … oh my goshhh, it was so delicious. His mother had crab legs before but just plain and no sauce and she absolutely loved this recipe, so did my boyfriend !!

Ingredients used for the Garlic Butter Seafood Boil Sauce:
- Butter- UNSALTED!
- Garlic
- Onion
- Chicken broth, vegetable broth, or water
- Lemon
- Tabasco sauce
- Seasonings: Lemon pepper, garlic powder, paprika, Old Bay seasoning, Cayenne pepper, Red pepper flakes
- Sweet chili sauce (optional)
How to prepare the sauce:
Gather all of the ingredients you need, it always makes life so much easier! Either thinly slice the onion, or chop it. Melt the stick of butter in a sauce pan over medium heat. Add the onion to the pan and saute for 5 minutes, or until the onion is translucent.
Roughly chop enough garlic to make 3 tablespoons, (about 2 whole heads of garlic, depending on size). After the onion is translucent, add the garlic to the pan. Saute the garlic for 30 seconds to 1 minute, stirring often so that it does not burn.
Now add the juice of one whole lemon. Use a lemon juicer if you have one available- to avoid getting seeds in the sauce. Sprinkle in all of the seasonings and stir.
Add additional butter (if desired, see next section), and chicken broth or water. Using the sweet chili sauce is optional (but recommended). It offers a sort of sweet heat for the sauce. Combine well and simmer on low-medium for about 15 minutes so sauce can thicken.
How to make the sauce a bit healthier:
To achieve a somewhat healthier, or less fatty sauce, use less butter! One stick is definitely recommended. Instead of all four sticks of butter though, just use one. Add chicken broth, vegetable broth, or water in place of the additional butter.
Use two cups of chicken or vegetable broth, and two cups of water. Or all four cups of water, or vegetable or chicken broth. Honestly, the flavor of the sauce is still amazing. With all of the seasonings and spices, it's super flavorful.
What if I don't like spicy food?
For spicy sauce, use the full amount of Cayenne and red pepper flakes. If no spice or less spice is desired, definitely decrease or omit these seasonings.
Another pointer here- definitely adjust the seasonings to your satisfaction! There have been several comments where people suggest too much seasoning is used. Well, I promise that this sauce is DELICIOUS! However, feel free to adjust accordingly.
Can I make the sauce ahead of time?
Absolutely! Make the sauce a day or two ahead of time if desired. Let the sauce cool down completely, and place it in an airtight container or jar.
Store the sauce in the refrigerator for up to one week. The sauce can also be placed in the freezer for up to 3 months. When you're ready to eat it, just pop-it in the microwave and heat it up until it is warm.
What to do with leftover Garlic Butter Sauce:
As mentioned above, let the sauce cool down completely and place it in an airtight container or jar, and store it in the refrigerator. The sauce an be stored in the fridge for up to one week.
Additionally, sauce can be stored in the freezer for up to 3 months. Leftover sauce always tastes SO much better! Grab it out of the refrigerator or freezer, and heat it up in the microwave or in a sauce pan over medium heat.
When to use the Seafood Boil Sauce:
Use the sauce to dip the seafood in after it is cooked. Or, make enough to pour over a seafood boil, and reserve some on the side to use for dipping.
When you check out the Garlic Butter Seafood Boil post, you will see a method for cooking the seafood in an oven bag. Pouring some of this sauce in the bag before putting it in the oven is the best method to cook it!
