Cajun Alfredo Sauce is a creamy, indulgent twist on the classic Italian Alfredo, infused with bold Cajun spices for a flavorful kick. This sauce balances rich butter and cream with zesty seasonings, making it perfect for pasta, chicken, shrimp, or rice dishes. It’s a wonderful way to add southern spice to a comforting favorite.

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 to taste)

Salt to taste (optional)

2 tablespoons olive oil (optional, for cooking proteins)

Fresh parsley, chopped (for garnish)

Instructions

Step 1: In a large skillet, melt the butter over medium-low heat. Add the minced garlic and cook until fragrant, about 1–2 minutes, being careful not to burn it.

Step 2: Sprinkle in the Cajun seasoning, smoked paprika, black pepper, cayenne pepper, and salt if using. Stir continuously for about 1 minute to bloom the spices without burning.

Step 3: Slowly pour in the heavy cream and bring to a gentle simmer over low heat, stirring often.

Step 4: Add the freshly grated Parmesan cheese and whisk continuously until the sauce becomes smooth and creamy.

Step 5: Let the sauce simmer for a few minutes, stirring occasionally, until it thickens to your desired consistency.

Step 6: Remove from heat. Garnish with chopped fresh parsley before serving over your choice of pasta, chicken, shrimp, or vegetables.

Tips & Variations

Use freshly grated Parmesan to ensure a smooth, creamy texture without graininess.

Adjust cayenne pepper to control the heat level based on your preference.

For a vegan version, replace heavy cream with cashew cream and Parmesan with nutritional yeast.

Try half-and-half instead of heavy cream for a lighter sauce without sacrificing too much creaminess.

Add sautéed vegetables like bell peppers or spinach for extra nutrients and flavor.

Storage

Store cooled Cajun Alfredo Sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, stirring frequently, and add a splash of cream or milk if the sauce has thickened too much. Freezing is possible but may cause separation; thaw overnight in the fridge and reheat carefully.
