To begin, start a pot of salted water to cook your fettuccine to package directions.
Meanwhile, melt the butter over low heat in a large skillet or sauce pan.
Add in the garlic and let it cook for just a few minutes, until it is tender.
Whisk in the cream and cream cheese. Heat and stir until smooth.
Stir in the nutmeg, parsley, salt, & pepper.
Add in the Parmesan cheese and whisk it in until melted.
Toss the cooked (drained) pasta with the sauce to coat.
Serve it with a little extra Parmesan cheese on top.
Enjoy!

Notes
When you drain your pasta, reserve some of the pasta water. After you toss your pasta with the sauce, if it is too thick, add some of the pasta water to thin it out a little.
