Description
A rich and flavorful Cajun Alfredo sauce that combines creamy Parmesan cheese with a spicy homemade Cajun seasoning. Perfect as a pasta sauce or a delicious base for Cajun chicken pasta, this creamy sauce features buttery richness, a touch of lemon zest for brightness, and a balanced heat from smoked paprika and cayenne pepper.
Ingredients
Cajun Alfredo Sauce
- ½ cup unsalted butter
- 1 ½ cup heavy cream
- 2 Tablespoons Cajun seasoning (homemade or store-bought)*
- ½ teaspoon kosher salt (omit if Cajun seasoning contains salt)
- 1¾ cup freshly grated Parmesan cheese
- Zest of 1 lemon
Homemade Cajun Seasoning
- 3 Tablespoons smoked paprika
- 1 Tablespoon onion powder
- 1 Tablespoon garlic powder
- 2 teaspoons 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
- Melt Butter: In a large skillet over low heat, melt the unsalted butter. Continue cooking gently until the butter is completely melted and begins to froth, forming small white bubbles on the surface.
- Add Cream and Seasoning: Stir in the heavy cream and Cajun seasoning. Add kosher salt if your seasoning blend does not contain salt. Bring the mixture to a gentle simmer while keeping the heat low. Let it cook for 5 to 6 minutes, stirring occasionally to blend flavors.
- Finish the Sauce: Remove the skillet from heat and add the lemon zest to the cream mixture. Gradually sprinkle in the freshly grated Parmesan cheese, stirring continuously until the cheese is fully melted and the sauce becomes smooth and creamy. Adjust salt to taste very carefully.
- Toss or Serve: Add cooked pasta directly into the pan and toss to coat the noodles evenly with the sauce. Serve immediately as desired. For a meal variation, add shredded cooked chicken and vegetables like peas or spinach.
Notes
- Be mindful of salt levels in store-bought Cajun seasoning, as some blends contain seasoning salt rather than just spices. Adjust salt accordingly.
- Do not add lemon juice directly to the hot cream base; using only lemon zest prevents curdling.
- If the sauce is too thick, thin it with a splash of reserved pasta cooking water.
- For Cajun Chicken Pasta, add 2 cups shredded cooked chicken and 12 to 16 ounces cooked pasta to the sauce. Frozen peas and spinach work well for added color and nutrition.
