Ingredients
- 2 sticks unsalted butter
- 12 cloves fresh garlic, minced
- 2 teaspoons Cajun seasoning
- 1 teaspoon Old Bay seasoning
- 1 tablespoon garlic powder
- 1 tablespoon onion powder
- ½ teaspoon lemon pepper seasoning
- 1 teaspoon cayenne pepper, or to taste
- ½ teaspoon black pepper
- ½ teaspoon crushed red pepper flakes
- 1½ tablespoons brown sugar
- 1 tablespoon olive oil
- 1 tablespoon fresh lemon juice
- 1 tablespoon Worcestershire sauce
- 1 teaspoon hot sauce, optional
Ingredient Notes
Cajun Seasoning
Cajun seasoning gives this sauce its bold, savory flavor, but the amount of salt can vary quite a bit between brands. I recommend starting with 2 teaspoons. If your Cajun seasoning is particularly salty, start with less and add more after tasting the finished sauce.
Old Bay Seasoning
Old Bay is one of my favorite seasonings for crab and seafood boils and adds that classic Chesapeake-style flavor. A little goes a long way in this sauce, especially when it’s combined with Cajun seasoning and Worcestershire sauce. Start with 1 teaspoon and taste the finished sauce before adding more.
Fresh Garlic
Fresh garlic creates the rich, savory flavor that makes this garlic butter sauce so irresistible. While garlic powder adds flavor, real minced garlic makes all the difference.
How To Keep The Sauce From Getting Too Salty
The biggest tip for this recipe is to taste before adding more seasoning. Cajun seasoning, Old Bay, lemon pepper, and Worcestershire sauce can all contribute salt, and the exact amount varies by brand. I use unsalted butter, so I have more control over the final flavor.
Keep in mind that your seafood boil ingredients may already be seasoned, too. It’s much easier to add another pinch of Cajun seasoning or Old Bay at the end than it is to fix a sauce that’s too salty.
Cayenne Pepper and Red Pepper Flakes
These ingredients control the spice level. Add a little bit for medium heat or increase the amount if you enjoy extra spice.
How To Make Juicy Crab Sauce
Step 1: Melt the Butter
Place the sticks of butter and olive oil in a small pot over medium heat.
Allow the butter to fully melt before moving to the next step.
Step 2: Cook the Garlic
Add the minced garlic and cook for about 1-2 minutes.
You want the garlic to become fragrant but not brown.
Step 3: Add the Seasonings
Whisk in:
- Cajun seasoning
- Old Bay seasoning
- Garlic powder
- Onion powder
- Lemon pepper
- Cayenne pepper
- Black pepper
- Red pepper flakes
- Brown sugar
Cook for another minute while stirring.
Step 4: Add the Remaining Ingredients
Stir in the fresh lemon juice, Worcestershire sauce, and hot sauce, if using.
Let everything simmer for 3–5 minutes.
Taste the sauce before adding any additional seasoning. If you want a stronger Cajun or Old Bay flavor, add a small pinch at a time until it tastes just right.
The finished sauce should be rich, buttery, garlicky, slightly spicy, and packed with flavor without tasting overly salty.
Step 5: Toss With Seafood
Pour the sauce over your favorite seafood and toss to coat.
Serve immediately.

Try it with:

Snow crab clusters
King crab legs
Dungeness crab
Blue crabs
Lobster tails
Jumbo shrimp

Shrimp boil
Mussels
Clams
You can even mix several types of seafood together for a fantastic seafood boil.

Tips For The Best Juicy Crab Sauce
- Use unsalted butter so you have complete control over the salt level.
- Use fresh garlic whenever possible for the best garlic butter flavor.
- Remember that Cajun seasoning, Old Bay, lemon pepper, and Worcestershire sauce can all contain salt.
- Taste the sauce before adding additional seasoning.
- If your Cajun seasoning is particularly salty, start with less and add more to taste.
- Adjust the cayenne pepper and red pepper flakes based on your preferred spice level.
- Add a little more fresh lemon juice if the finished sauce needs some brightness.
- Keep in mind that sausage and seasoned seafood can add even more salt once everything is tossed together.
- Don’t overcook the garlic, or it can develop a bitter taste.
Make It Ahead
You can make the sauce ahead of time and store it in an airtight container in the refrigerator for up to 5 days.
When you’re ready to serve, simply reheat it in a small pot over low heat until warmed through.
This makes meal prep for a delicious seafood boil much easier.
