Combine all of these ingredients in a dutch oven: grated parmesan cheese, kosher salt, black pepper, nutmeg, whipped cream cheese, unsalted butter, heavy cream, and minced garlic. Place the dutch oven in the grill or oven for 30 minutes at 275F to soften everything. Mix it all together (a hand blender can be used). Once everything is smooth, add in a pound of cooked fettuccine pasta and enjoy. Optionally, top with more grated parmesan and parsley.
