Begin by placing a medium-sized saucepan over low heat. Add in the unsalted butter, allowing it to melt gently, which should take about 2-3 minutes.

Once the butter has melted, add the minced garlic to the saucepan. Sauté gently for about 1 minute, stirring frequently until fragrant and translucent.

Next, stir in the Cajun seasoning and smoked paprika, mixing well to ensure they incorporate into the buttery mixture.

Pour in the freshly squeezed lemon juice and add the chopped parsley. Stir together vigorously for about 30 seconds.

Taste your Cajun Garlic Butter Sauce and adjust the seasonings by adding a pinch of salt or more Cajun spice as needed.

For a silkier texture, consider using an immersion blender at this point to blend the sauce briefly until smooth.

Serve immediately over your choice of grilled chicken, shrimp, pasta, or roasted vegetables.
