Ingredients

Scale

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 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 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 ½ cup unsalted butter in a large skillet over low heat until melted and it begins to froth with white bubbles on top.
  2. Add Cream and Seasoning: Stir in 1 ½ cup heavy cream and 2 Tablespoons Cajun seasoning. Add ½ teaspoon kosher salt if needed. Bring to a simmer and cook on low heat for 5 to 6 minutes until slightly thickened.
  3. Add Lemon Zest and Cheese: Remove the pan from heat, add the zest of 1 lemon, then gradually add 1¾ cup freshly grated parmesan cheese, stirring continuously until the cheese is completely melted and the sauce is smooth. Adjust salt to taste.
  4. Toss with Pasta or Serve: Add cooked pasta to the pan and toss to coat evenly with the sauce, or serve the sauce as desired alongside your dish.

Notes

  • Be mindful of the salt content in store-bought Cajun seasoning; many contain seasoning salts rather than spice blends. For best results, use the homemade seasoning recipe provided.
  • Do not add lemon juice to bubbling cream as it may cause curdling; use only lemon zest for flavor.
  • If the sauce is too thick, thin it with a small amount of reserved pasta water.
  • To make Cajun Chicken Pasta, add 2 cups shredded cooked chicken and 12 to 16 ounces cooked pasta along with the sauce. Frozen peas and spinach are excellent additions.
