How To Make the Spicy Cajun Garlic Butter Sauce

Step 1: Melt the Butter

In a small saucepan over medium heat, melt the butter slowly to avoid browning. Stir occasionally as it begins to bubble.

Step 2: Add the Garlic

Once the butter is melted, add in the freshly minced or pressed garlic. Sauté for about 30 seconds until fragrant, being careful not to burn it.

Step 3: Spice it Up

Sprinkle in the Cajun seasoning, smoked paprika, and red pepper flakes. Stir thoroughly to combine with the butter and garlic.

Step 4: Add the Citrus

Squeeze in the lemon juice and give it a stir. This balances out the heat and richness beautifully.

Step 5: Finish with Herbs

Add chopped parsley and a pinch of salt if needed. Let the sauce simmer for another 1-2 minutes, then remove from heat.

Your spicy Cajun garlic butter sauce is now ready to serve!
