How to Make Cajun Alfredo Sauce – Step-by-Step Instructions

1. Melt the butter in a skillet over medium heat. Once melted, add the minced garlic and cook for 1–2 minutes until fragrant.
2. Sprinkle in Cajun seasoning and stir to coat the garlic and butter. This step blooms the spices, enhancing the overall flavor.
3. Pour in the heavy cream and stir continuously. Let the cream warm up for about 2–3 minutes, just until it starts to gently bubble around the edges.
4. Add parmesan cheese gradually, stirring constantly to ensure it melts smoothly into the sauce. Avoid letting the mixture boil to prevent curdling.
5. Taste and season with a pinch of salt and pepper. If the Cajun seasoning is salty, go light on added salt.
6. Serve hot over your favorite pasta, with grilled chicken, shrimp, or roasted vegetables.

This sauce thickens as it cools, making it perfect for coating pasta. For a hearty pairing, try it with Stuffed Acorn Squash or Sweet Potato Hash for a comforting dinner.
