Sauce Ingredients

  • 1/2 cup unsalted butter
  • 1 1/2 cup heavy cream
  • 2 Tablespoons Cajun seasoning (homemade or store bought)
  • 1/2 teaspoon kosher salt (omit if your seasoning blend contains salt)
  • 1 3/4 cup freshly grated parmesan cheese
  • 1 lemon (zest only)
  • 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
  • 1/2 teaspoon dried basil

Instructions

  1. Melt the Butter: Melt the unsalted butter in a large skillet over low heat until fully melted and it begins to froth, showing white bubbles on top, which helps infuse the flavor throughout the sauce.
  2. Add Cream and Seasoning: Stir in the heavy cream and Cajun seasoning blend. Add kosher salt at this stage only if your seasoning mix does not contain salt. Bring the mixture to a gentle simmer and cook on low heat for 5 to 6 minutes to allow the flavors to meld and the sauce to thicken slightly.
  3. Incorporate Lemon Zest and Cheese: Remove the skillet from the heat and add lemon zest for a fresh, citrus brightness. Gradually add the freshly grated parmesan cheese while stirring continuously until the cheese melts completely and the sauce becomes smooth and creamy. Adjust salt to taste.
  4. Serve: Add cooked pasta to the skillet and toss well to coat evenly with the sauce, or serve the sauce separately as desired. Enjoy immediately for best flavor and texture.

Notes

  • Use freshly grated parmesan cheese for the best texture and flavor.
  • Adjust the salt depending on the saltiness of your Cajun seasoning blend.
  • For a thicker sauce, simmer a little longer; for thinner sauce, add a splash of cream or pasta water.
  • The sauce works beautifully over fettuccine, linguine, or penne.
