Ingredients
A few simple ingredients go a long way for this
Butter: the star of the show, of course. Melted butter is the basis of this sauce. I used salted butter but feel free to use unsalted to control the saltiness of the sauce.
Yellow Onion and Fresh Garlic: these give the sauce a delicious aromatic flavor that goes so well with seafood. pro tip - dice the onions as finely as possible!
Homemade Seafood Seasoning mix: cajun seasoning, old bay seasoning, onion powder, and red pepper flakes. Salt and black pepper, to taste, of course.
Brown Sugar: hear me out - the sugar balances all of the salty flavors and makes this sauce divine. It doesn't make it sweet at all so don't worry about having a seafood boil dipping sauce that's sugary.
Chicken stock: the stock adds an additional layer of flavoring to the sauce and also loosens it up a bit. If you can't find stock, chicken broth works too.
Lemon juice: the lemon juices adds brightness to the sauce and gives it a slight citrus flavor.
Tips
Adjust the spice level to your liking by adding more (or less) red pepper flakes. If you want add extra spice, add a dash of hot sauce. I'm super sensitive to hot foods and would say that this sauce is pretty mild and flavorful. Taste as you go and adjust the ingredients as per your liking. See the recipe card for exact measurements.
Dice onions and garlic and finely as possible. This is key to releasing the flavors when cooking it in the butter.
If you prefer a thinner sauce, add another ½ cup of chicken stock.
Not all cajun seasonings are created equally. Some brands are salt free and others include salt in their blend. Be mindful of this while cooking and taste as you go to prevent having a sauce that's too spicy or too salty.
If you'd like to add a little bit of umami flavor, add some Worcestershire sauce.

I've always been intimidated to make a seafood boil at home but your recipe got me knocking it out of the park! The garlic, butter and seasoning is ridiculously good. I'm already planning to have some family and friends over in a few weeks to do this again!
It seems that my comment was lost. This is the PERFECT boil that keeps me from having to head to the seafood boil restaurant too many times in one month. Perfect butter to seasoning ration and the flavor is DIVINE!
I’ve only had seafood boil a few times and I’ve always wanted to try to make the sauce at home but never knew where to start. Your recipe saved the day! It was flavourful and so easy to follow. I am saving this for later too.
This Seafood Boil Sauce is the thing I did not know was missing in my life. I made a little extra to keep in the refrigerator to pour over vegetables and chicken wings. Delectable!
Hey Britney! I made your seafood boil sauce for my family's crab feast and it was a total game-changer! Everyone loved the rich, garlicky goodness and kept asking for your recipe. Thank you so much. xx
As someone who spent a few years living in Maryland, I can say with authority that this is a legit seafood boil sauce if not one that sets the standard. All of the flavors were on point and really elevated the taste of my plain seafood.
Really good. Better than most restaurants!
Thank you!
By far the best sauce I've ever had.
Thank you!
I used your sauce recipe for our first boil of the season and it was a hit! No leftovers. Thank you!
