A peek at the flavorful ingredients that come together to create this delicious sauce.

Directions

  1. In a large skillet, melt the butter over low heat until it begins to froth with white bubbles on top.
  2. Stir in the heavy cream and Cajun seasoning, adding salt if necessary. Bring the mixture to a gentle simmer and let it cook on low for 5 to 6 minutes.
  3. Remove the pan from heat and add the lemon zest.
  4. Gradually whisk in the parmesan cheese, stirring until it is completely melted and the sauce is smooth. Taste and adjust salt as needed.
  5. Add your cooked pasta to the pan, tossing to coat in the rich sauce, or serve it as desired.

Tips & Variations

  • Ingredient Substitutions: If you’re in a pinch, you can use half-and-half instead of heavy cream for a lighter sauce. For a dairy-free option, coconut cream works well, but note that it will give a slightly different flavor.
  • Optional Variations: Spice it up further with additional red pepper flakes or add sautéed mushrooms or spinach for extra flavor and nutrition.
  • Storage or Reheating Tips: Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm on the stovetop over low heat, adding a splash of cream if the sauce has thickened.
