What Kind of Butter Should I Use?

Ingredients for the Cajun Garlic Butter Sauce

Butter – This is the creamy, rich base of the sauce. It creates that smooth, luscious texture we all love.

Garlic – Fresh minced garlic is essential. It adds depth and that signature aroma you expect in a garlic butter sauce.

Cajun Seasoning – This brings the bold heat and smoky flair. You can use a store-bought mix or make your own if you prefer to tweak the spice level.

Crushed Red Pepper Flakes – Adds a bit more kick, perfect for spice lovers.

Paprika – Smoked or sweet, it adds warmth and color to the sauce.

Lemon Juice – A bright acidic note to cut through the richness.

Parsley – Fresh chopped parsley finishes the sauce with a burst of color and freshness.

Salt and Black Pepper – Enhances and balances all the other flavors.

How To Make the Cajun Garlic Butter Sauce

Step 1: Melt the Butter

In a small saucepan over medium heat, melt the butter until completely liquified but not browned.

Step 2: Add Garlic and Sizzle

Stir in the minced garlic and cook for about 30 seconds to 1 minute until fragrant. Don’t let it brown!

Step 3: Stir in the Spices

Add Cajun seasoning, crushed red pepper flakes, and paprika. Stir well to combine and let the spices bloom for another 30 seconds.

Step 4: Brighten with Lemon Juice

Remove the pan from heat and immediately stir in the fresh lemon juice. This keeps the flavor sharp and vibrant.

Step 5: Finish with Herbs

Toss in chopped parsley, salt, and black pepper to taste. Give the sauce a final stir and it’s ready to serve.

Best Ways to Serve and Store Cajun Garlic Butter Sauce

This sauce is incredibly versatile. Drizzle it over seafood like shrimp, crab legs, or grilled fish. Toss it with pasta, rice, or roasted veggies for a bold finish. It’s also amazing as a dipping sauce for crusty bread or poured over a baked potato.
