Introduction

This Cajun Alfredo Sauce is a creamy, flavorful twist on the classic Italian favorite. Blended with bold Cajun spices and parmesan cheese, it’s perfect for jazzing up pasta, chicken, or shrimp dishes with a little heat and smoky depth.

A round silver pan filled with two main layers; the bottom layer is a thick, creamy orange sauce with specks of herbs and spices, while the top layer consists of fresh, uncooked, flat white pasta strips loosely piled in the center. The pan sits on a white marbled textured surface, with a gray and white cloth partially visible under the pan's handle, and some green leafy herbs in the top right corner.

Ingredients

4 tablespoons unsalted butter
4 cloves garlic, minced
2 cups heavy cream (or half-and-half for a lighter version)
1 ½ cups freshly grated Parmesan cheese
2 tablespoons Cajun seasoning
½ teaspoon smoked paprika (optional)
½ teaspoon freshly ground black pepper
¼ teaspoon cayenne pepper (adjust for heat preference)
Salt to taste
2 tablespoons olive oil (optional, for cooking proteins)
Fresh parsley, chopped (for garnish)

Instructions

Step 1: In a large skillet, melt the unsalted butter over medium heat.
Step 2: Add the minced garlic and cook until fragrant, about 1–2 minutes, being careful not to burn it.
Step 3: Sprinkle in Cajun seasoning, smoked paprika, black pepper, cayenne pepper, and salt to taste. Stir continuously to prevent the spices from burning and to evenly distribute the flavors.
Step 4: Pour in the heavy cream and reduce the heat to low. Let the mixture simmer gently for a few minutes, stirring occasionally.
Step 5: Gradually add the freshly grated Parmesan cheese while whisking the sauce until smooth and creamy.
Step 6: If the sauce is too thin, continue simmering for a few more minutes until it thickens to your desired consistency.
Step 7: Optionally, cook proteins like chicken or shrimp in olive oil separately, then combine with the sauce.
Step 8: Garnish with chopped fresh parsley before serving.

Tips & Variations

Use freshly grated Parmesan for the best taste and texture; pre-shredded cheese may not melt as smoothly.
Adjust the cayenne pepper to increase or decrease the heat according to your preference.
For a lighter sauce, substitute half the heavy cream with half-and-half or milk, but be mindful the sauce may be less rich.
Try adding cooked andouille sausage or sautéed mushrooms to enhance the Cajun flavor.
If you prefer a thicker sauce, mix a small amount of cornstarch with cold water and whisk into the sauce while simmering.

Storage

Store any leftover Cajun Alfredo Sauce in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently on the stovetop over low heat, stirring frequently to prevent separation. Add a splash of cream or milk if the sauce has thickened too much.

How to Serve

A white bowl filled with creamy pasta coated in a rich, light orange sauce, layered evenly and topped with finely chopped green herbs and a sprinkling of grated white cheese. On the side inside the bowl, there is a small bunch of fresh green microgreens and a bright yellow lemon wedge resting on the rim, adding a fresh contrast to the warm pasta. The bowl sits on a wooden board placed on a white marbled surface, with green parsley leaves slightly blurred in the background. photo taken with an iphone --ar 4:5 --v 7
