In a medium saucepan, pour in 1 cup of heavy whipping cream and add 2 teaspoons of Cajun seasoning, 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and ¼ cup of dry white wine. Stir these ingredients together thoroughly until well mixed.

Place the saucepan on the stovetop over medium-low heat. Gently heat the mixture, stirring occasionally, until you see small bubbles forming around the edges, indicating it’s just about to simmer. This should take around 5 minutes.

Once the sauce reaches a gentle simmer, add in ½ cup of grated Parmesan cheese. Stir continuously for about 3 to 5 minutes until the cheese is completely melted and the sauce slightly thickens.

If the sauce is too thick, add a splash of water or chicken broth while stirring, and allow it to cook for another minute to reach desired consistency.

Serve the sauce hot over pasta, grilled chicken, or seafood. Store any leftover sauce in an airtight container in the refrigerator for up to 5 days.
