Ingredients for Cajun Alfredo Sauce
- 2 tablespoon unsalted butter
- 4 garlic cloves, minced
- 1 ½ cups heavy cream
- 1 cup freshly grated Parmesan cheese
- 1 teaspoon Cajun seasoning (add more to taste)
- ½ teaspoon smoked paprika

- 2 tablespoon fresh parsley, chopped (for serving)
How to Make Cajun Alfredo Sauce
Step 1: Sauté the Garlic
In a large skillet over medium heat, melt the butter. Add minced garlic and sauté for 1-2 minutes until fragrant, but not browned.
Step 2: Create the Creamy Base
Pour in the heavy cream, stirring continuously. Bring to a gentle simmer, then reduce heat to low. Add Cajun seasoning, smoked paprika, salt, pepper, and (if using) red pepper flakes. Simmer for 2-3 minutes to let the flavors meld.
Step 3: Add the Cheeses
Stir in Parmesan cheese and cream cheese (if using). Continue stirring until all cheese melts and the sauce becomes silky and thick, about 4-5 minutes.
Step 4: Final Touches
Taste and adjust seasoning as needed. Remove from heat. Sprinkle with chopped parsley. Serve immediately over your favorite pasta or protein!
Notes for the Best Cajun Alfredo Sauce
- Use freshly grated Parmesan for the smoothest, creamiest finish—pre-shredded cheese can make your sauce grainy (read more).
- If your sauce gets too thick, whisk in a splash of milk or pasta water to loosen it.
- For spice control, start with less Cajun seasoning, then adjust to taste (learn about Cajun blends).
