Crafty Crab Boom Sauce Recipe

Crafty Crab Boom sauce is a delicious blend of Cajun seasoning, lemon pepper, and garlic butter.

Traditionally served with seafood boils, this sauce will give a burst of flavor to any of your favorite dishes.

The original comes from the restaurant chain of the same name. However, getting a hold of their recipe makes breaking into Fort Knox look easy.

So I’ve put together a Crafty Crab Boom sauce recipe that’s easy to make at home while still having all the great flavors of the original.

Read on and learn how to make a delicious Crafty Crab Boom sauce that will give a taste of the bayou to all your favorite dishes.

What Do You Need To Make Crafty Crab Boom Sauce


Unsalted Butter

Butter is the base of this sauce.

Unsalted butter has a higher fat content than salted butter: more fat means more flavor.

You can use salted butter in a pinch, but be sure you taste it before adding additional salt to avoid over-seasoning.

Cajun Seasoning 

The key to making a delicious Crafty Crab Boom sauce.

Use the Cajun seasoning recipe provided or substitute your favorite store-bought blend.

Fresh Garlic 

Intensifies the flavor. Finely mince the garlic or use a garlic press.

You can substitute garlic powder.

However, make sure you don’t use garlic salt, which will overpower your sauce. Feel free to add more garlic to suit your taste.

Fresh Onion

Deepens the flavor of the sauce. You can substitute onion powder to save time.

Lemon Juice

The lemon juice cuts through the fat in the butter to balance out the sauce.

If at all possible, use fresh lemon.

If you don’t have access to fresh lemons, you can use two tbsp of bottled lemon juice instead.


Mustard gives the sauce some tang.

I like dijon mustard for this recipe, but you can experiment with other mustards.

Fresh Parsley

Gives your sauce a spot of color.

Salt and Black Pepper

I recommend using coarse sea salt and freshly ground black pepper.

The salt unlocks the other flavors, but be sure you taste it so you don’t over-season your sauce.

Other Things To Consider When Making Crafty Crab Boom Sauce

You Can Substitute Ingredients

Feel free to substitute any ingredient or change any amounts to suit your taste.

For example, add some lemon rind to give your sauce some zing. I always sprinkle red pepper flakes in my sauce to give it that extra punch.

The bottom line is to have fun with this recipe and try different variations. You may find that your version tastes better than the original.

What Can I Eat with Crafty Crab Boom Sauce?

Besides traditional seafood boils, Crafty Crab Boom sauce will add great Cajun flavor to a wide variety of your favorite dishes.

  • Drizzle it over grilled vegetables to make them pop.
  • Mix with boiled or grilled red potatoes for a delicious side dish.
  • Serve as a dipping sauce for lobster, crab, or shrimp instead of traditional lemon butter.
  • Use as a marinade for steaks and chicken to give them that unique taste of the bayou.
  • Goes great with grilled or blackened fish, like cod, halibut, or snapper.
  • Serve melted or chilled with crusty sourdough bread. Delicious!

Make More Than You Need!

Crafty Crab Boom sauce adds an explosion of flavor to more than just seafood.

So feel free to double the recipe. It keeps well in the fridge for up to two weeks.

Or in the freezer for up to three months.

I like to freeze my extra sauce in ice-cube trays.

That way, I can heat up a couple of cubes whenever I want to add a bit of spicy Cajun flavor.

Crafty Crab Boom Sauce Recipe

Crafty Crab Boom Sauce

This copycat Crafty Crab Boom Sauce enables you to create your favorite sauce from Crafty Crab from the comfort of your own home. Enjoy dipping or pouring it over seafood!

Prep Time 5 minutes
Cook Time 10 minutes
Total Time 15 minutes


  • 2 sticks of unsalted butter
  • 8 garlic cloves, peeled and finely minced
  • ¼ cup white onion, diced
  • 3 tbsp Cajun seasoning (see recipe below)
  • 1 tsp ground black pepper
  • Juice from one lemon
  • 1 tbsp dijon mustard
  • 2 tbsp fresh parsley, minced
  • Salt and pepper to taste (I recommend coarse sea salt)


  1. Peel and finely mince the garlic cloves. You can use a garlic press instead of mincing.
  2. Peel and finely dice the fresh onion.
  3. Add one stick of butter to the saucepan and heat on medium heat until just melted.
  4. Add the onion, garlic, and lemon juice to the saucepan and saute until soft and slightly brown, approximately five minutes. I like to add a pinch of salt to help soften the onion. They should turn a nice light brown color, but make sure you don't burn them. If necessary, reduce the heat.
  5. Add the remaining butter, ground black pepper, Cajun seasoning, mustard, and fresh parsley, and allow the butter to melt. Stir well to blend all the ingredients.
  6. Adjust any of the ingredients to suit your desired taste.
  7. Season with salt and black pepper, if necessary.
  8. Enjoy!


  • Want more heat? Sprinkle in some red pepper flakes.
  • Feel free to substitute your favorite Cajun seasoning blend instead of making your own.
  • Want more lemon flavor? Add a little lemon zest to give it some zing.
  • Add a few drops of liquid smoke for a smokier, more intense flavor.
  • Use a sweet white onion instead of the white onion to give Crafty Crab Boom sauce a less intense onion flavor.
  • Use cilantro instead of fresh parsley for a bit of Caribbean flair.
  • Don't have a lot of time? You can substitute one teaspoon of garlic powder and ¼ teaspoon of onion powder instead of the fresh garlic and onions.

Homemade Cajun Seasoning Recipe

  • 3 tbsp smoked paprika
  • 1 tbsp coarse sea salt
  • 1 tsp ground black pepper
  • 1 tsp ground mustard
  • 1 tsp dried oregano
  • 1 tsp dried thyme
  • 1 tsp cayenne pepper

Combine all the spices for the Cajun seasoning.

Note: this recipe makes more Cajun seasoning than you'll need for the butter. Store it in an airtight container and use it to spice up grilled meats, chicken, fish, and vegetables.
