What Kind of Butter Should I Use?

For the richest flavor, always choose unsalted butter when making garlic butter sauces. This gives you full control over the salt levels, especially when combining with seasoning blends like Cajun spice that already contain sodium.

High-quality European butter or grass-fed butter will make the sauce extra creamy and flavorful.

Ingredients for the Spicy Cajun Garlic Butter Sauce

• Unsalted Butter: The base of the sauce. Rich and creamy, it melts down into a luscious medium to carry all the flavor.
• Fresh Garlic: Minced or grated garlic infuses the sauce with bold, aromatic depth.
• Cajun Seasoning: Brings the heat and signature Southern spice with paprika, cayenne, garlic powder, and herbs.
• Paprika: Adds mild smokiness and enhances the vibrant red color.
• Crushed Red Pepper Flakes: Optional, but perfect for cranking up the spice.
• Fresh Parsley: Adds a bright, fresh finish to balance the bold spices.
• Lemon Juice: Just a splash to cut through the richness and balance the butter.

How To Make the Spicy Cajun Garlic Butter Sauce

Step 1: Melt the Butter

In a small saucepan over medium heat, melt the unsalted butter slowly. Stir occasionally to prevent browning.

Step 2: Add Garlic

Once the butter is melted, stir in the minced garlic. Sauté for about 1 minute until fragrant. Be careful not to let it burn.

Step 3: Season It Up

Add the Cajun seasoning, paprika, and red pepper flakes (if using). Stir well to combine all the spices with the butter.

Step 4: Finish With Freshness

Turn off the heat and stir in chopped fresh parsley and a squeeze of lemon juice. Let the sauce sit for a minute to allow the flavors to bloom.
