This cajun butter sauce recipe is easy to pull together and bursting with rich, spicy flavors! It's a rich and flavorful sauce for seafood lovers that packs a little heat.
It's perfect for a seafood dipping sauce - it pairs so well with lobster tails, snow crab legs, king crab legs, and jumbo shrimp. You can also toss it with seafood, fresh corn, and potatoes and use it for a seafood boil.

Emily's Recipe Notes
My seafood sauce packs in the spices! I use several dry spices - Old Bay Seasoning, Cajun seasoning, and smoked paprika to punch up the flavors and then I bring in richness with Worcestershire sauce.
You can serve it with a plate of grilled shrimp or crab for dipping, or use it in one of my all-time favorite ways - a shrimp seafood boil!

Cajun Butter Sauce Ingredients
- Unsalted Butter - Make sure to use real butter. It provides the rich flavor in this recipe.
- Yellow Onion and garlic cloves - Fresh garlic and onion will mix with the butter to provide the aromatics and add a deep and slightly sweet flavor.
- Cajun Seasoning - You can make your own seasoning or purchase from the store. Cajun seasoning is a blend of cayenne pepper, paprika, garlic powder, pepper, onion powder, and oregano.
- Smoked Paprika - adds a little smoky flavor and richness to the sauce.
- Worcestershire sauce - packs a punch of umami flavor.
- Lemon Juice - Lemon provides just the right amount of acidity and adds a bright flavor to this sauce.
- Old Bay Seasoning - Red pepper flakes, celery seed, mustard, paprika, ginger, black pepper, and several other aromatics are used in this seasoning blend.

How to Use This Sauce
