Sauce Ingredients

  • ½ cup unsalted butter
  • 1 ½ cup heavy cream
  • 2 Tablespoons Cajun seasoning (homemade or store bought)
  • ½ teaspoon kosher salt (omit if your seasoning blend contains salt)
  • 1¾ cup freshly grated parmesan cheese
  • Zest of 1 lemon
  • 3 Tablespoons smoked paprika
  • 1 Tablespoon onion powder
  • 1 Tablespoon garlic powder
  • 2 teaspoon kosher salt
  • 1 teaspoon ground white pepper
  • 1 teaspoon ground mustard
  • 1 teaspoon dried oregano
  • 1 teaspoon dried thyme
  • 1 teaspoon cayenne pepper
  • ½ teaspoon dried basil

Instructions

  1. Melt Butter: Melt the butter in a large skillet over low heat until completely melted and it begins to froth with white bubbles forming on top.
  2. Add Cream and Seasoning: Stir in the heavy cream and Cajun seasoning. Add salt if needed. Bring the mixture to a simmer and cook on low heat for 5 to 6 minutes to allow the flavors to meld and the sauce to thicken slightly.
  3. Add Lemon Zest and Cheese: Remove the pan from the heat, add the lemon zest, then gradually add the freshly grated parmesan cheese. Stir continuously until the parmesan is fully melted and the sauce becomes smooth and creamy. Adjust salt to taste.
  4. Toss with Pasta or Serve: Add cooked pasta directly to the pan and toss to coat evenly with the Cajun Alfredo sauce, or serve the sauce as desired alongside your dish.

Notes

  • Use freshly grated parmesan cheese for best melting and flavor.
  • If your Cajun seasoning contains salt, omit or reduce the additional salt added.
  • This sauce pairs wonderfully with fettuccine, penne, or your preferred pasta.
  • You can customize spiciness by adjusting the amount of cayenne pepper or Cajun seasoning.
  • Store leftover sauce in an airtight container in the refrigerator for up to 3 days; reheat gently while stirring.
