  3. Add the Cream: Pour in the heavy cream and stir continuously using a whisk.
  4. Simmer the Sauce: Allow the sauce to simmer for 4–5 minutes, stirring constantly to avoid sticking.
  5. Incorporate the Cheese: Slowly whisk in Parmesan cheese until fully melted and sauce thickens.
  6. Season the Sauce: Season with salt, pepper, and a pinch of nutmeg if desired.
  7. Rest the Sauce: Let the sauce rest for 2 minutes to blend flavors and thicken naturally.

Notes

  • Use freshly grated Parmesan, not pre-shredded, for best melting and flavor.
  • Stir constantly to prevent burning or separation of fats.
  • Add cream cheese for extra thickness and richness if desired.
  • Serve immediately for best texture; sauce thickens as it cools.
  • You can double the batch and store leftovers for 3 days refrigerated.
