In a large skillet over medium-low heat, add butter, heavy whipping cream, and cream cheese (if using). Stir over medium-low heat for about 2 minutes until melted, and it starts to lightly simmer.
Next, whisk in the minced garlic, Italian seasoning, salt, and pepper for one minute. Note: For extra garlicky flavor, first melt the butter, add the garlic, cook for 1 minute, and then add the ingredients from step 1.
Reduce heat to low, add the shredded Parmesan cheese, and continue to whisk until melted.
You can serve immediately with your favorite pasta.
For a very subtle nutty flavor, sprinkle some nutmeg on top before serving.
