  • Total Time: 15 minutes
  • Yield: About 2 ½ cups (enough to serve 4)

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 seasoning blend contains salt)
  • 1¾ cup freshly grated Parmesan cheese
  • 1 lemon (zest only)

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

  1. Melt the butter: Place the unsalted butter in a large skillet over low heat. Allow it to melt completely and begin to froth, indicated by white bubbles forming on top.
  2. Add cream and seasonings: Stir in the heavy cream and Cajun seasoning. If your seasoning blend doesn’t contain salt, add ½ teaspoon kosher salt. Bring the mixture to a gentle simmer, then cook on low heat for 5 to 6 minutes to thicken and develop flavor.
  3. Add lemon zest and cheese: Remove the pan from heat and stir in the lemon zest. Gradually add the freshly grated Parmesan cheese, stirring continuously until it melts completely and the sauce becomes smooth and creamy. Taste and adjust salt if necessary.
  4. Coat pasta or serve: Add cooked pasta directly to the pan and toss to evenly coat with the sauce, or serve the sauce as desired with your dish.

Notes

  • Be cautious of the salt content in store-bought Cajun seasonings, as many are seasoning salts rather than pure spice blends. For best results, use the homemade Cajun seasoning recipe provided.
  • Avoid adding lemon juice to hot, bubbling cream as this may cause curdling—use only lemon zest for flavor.
  • If the sauce becomes too thick, thin it out with a splash of reserved pasta cooking water.
  • For a quick Cajun chicken pasta meal, add 2 cups shredded cooked chicken and 12 to 16 ounces of cooked pasta to the sauce. Frozen peas and spinach make excellent additions for extra color and nutrition.
