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 heat preference)
Salt to taste
2 tablespoons olive oil (optional, for cooking proteins)
Fresh parsley, chopped (for garnish)

Instructions

Step 1: Melt the butter in a large skillet over medium heat. Add the minced garlic and cook until fragrant, about 1–2 minutes, being careful not to brown it.
Step 2: Stir in the Cajun seasoning, smoked paprika, black pepper, cayenne pepper, and salt if needed. Cook, stirring continuously, for about 1 minute to toast the spices and release their aroma.
Step 3: Pour in the heavy cream and bring to a gentle simmer. Let it cook for 3–5 minutes, stirring occasionally, until it slightly thickens.
Step 4: Gradually whisk in the freshly grated Parmesan cheese until the sauce is smooth and creamy.
Step 5: If the sauce is too thin, continue simmering gently for a few more minutes until desired thickness is reached. Remove from heat and serve immediately.

Tips & Variations

Use half-and-half instead of heavy cream for a lighter sauce, but expect a slightly thinner texture.
Adjust cayenne pepper amount to control the heat level according to your preference.
For extra flavor, cook chicken or shrimp in olive oil before adding the sauce and serve them together.
Freshly grate your Parmesan cheese to ensure a smoother melt and richer taste.

Storage

Store leftover Cajun Alfredo Sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove over low heat, stirring frequently to avoid separating. You may add a splash of cream or milk to loosen the sauce while reheating if it has thickened too much.
