Melt the butter in a large pan over medium heat.
Gently swirl the pan to coat the surface evenly and prevent sticking.
Slowly pour in the heavy cream.
Stir continuously to keep it from scorching.
Add the cream cheese in chunks, allowing it to melt completely.
Stir until the mixture is smooth and well-combined.
Gradually sprinkle in the Parmesan cheese.
Stir the sauce thoroughly to blend the cheese and achieve a creamy texture.
Season with salt and black pepper to taste.
Continue stirring until the sauce thickens to your desired consistency.
