How To Make the Spicy Cajun Garlic Butter Sauce
Step 1: Melt and Sizzle
Start by melting the unsalted butter in a small saucepan over medium heat. Let it melt slowly so it doesn’t brown.
Step 2: Sauté the Garlic
Once the butter is melted, add in the minced garlic. Stir frequently and cook for about a minute until fragrant but not browned.
Step 3: Spice It Up
Stir in the Cajun seasoning, paprika, crushed red pepper flakes, and salt. Let the spices toast gently in the butter for about 30 seconds to release their aromas.
Step 4: Finish with Lemon
Remove the pan from heat and stir in the lemon juice. This brightens everything up and gives the sauce a final pop.
Step 5: Serve
Use immediately while hot or pour it into a jar to store. Give it a quick stir before serving if it separates.
