Ingredients
- 2 tablespoons unsalted butter
- 1.5 cups heavy cream
- 1 tablespoon Cajun seasoning mix
- 1 teaspoon kosher salt
- 1 teaspoon lemon zest
- 1.75 cups freshly grated Parmesan cheese
- 0.5 teaspoon cayenne pepper
- Black pepper to taste
Instructions
- Step 1: Melt the butter in a large skillet over low heat until it becomes frothy, about 2 minutes.
- Step 2: Add the heavy cream and Cajun seasoning to the skillet. Stir in kosher salt if desired, then simmer for 5 to 6 minutes until the sauce slightly thickens.
- Step 3: Remove the skillet from heat. Stir in the lemon zest, then gradually add the Parmesan cheese, stirring to ensure it melts smoothly into the sauce.
- Step 4: Adjust the seasoning by adding more salt or black pepper to taste. Stir in the cayenne pepper for an extra heat punch.

Tips & Variations
- For a milder sauce, reduce or omit the cayenne pepper. For extra creaminess, add a splash of milk or more heavy cream.
- Try adding cooked chicken or shrimp for a complete Cajun-inspired meal.
- Use freshly grated Parmesan for the best texture and flavor—it melts more smoothly than pre-grated cheese.
Storage
Store leftover Cajun Alfredo sauce in an airtight container in the refrigerator for up to 3 days. When reheating, warm gently over low heat and stir frequently to prevent separation. You may add a little cream or milk to loosen the sauce if it thickens too much.
