Maybe not the "light" recipe you were looking for but my motto is "all things in moderation." My friend Kaydee made this for a Mother-Daughter dinner we had and it was a big hit. Creamy and smooth, just the way I like it. Lots of times I'll saute some sliced chicken breast seasoned with salt, pepper and garlic to throw on the top.
1 qt. heavy whipping cream
1 c. butter
4 T. cream cheese
1 1/2 c. fresh Parmesan cheese, grated
2 tsp. garlic powder
1 (12oz) pkg. Fettuccine noodles ( I use whatever)
Combine cream, butter, and cream cheese; simmer until melted. Add Parmesan cheese and garlic powder. Simmer for 20-30 min on low. Add salt and pepper to taste.
