I was craving lasagna but didn't want to layer and bake for hours, so I turned it into soup instead — and honestly, it's better this way. The kitchen smelled like garlic bread and melted cheese before I even added the noodles. I stirred in a splash of cream at the end and it turned into this silky, dreamy hug in a bowl. My husband came home and said it smelled like Nonna's kitchen, and I nearly cried. This is the kind of recipe that makes you want to light a candle, pour some juice, and pretend you're in a cozy Italian trattoria.
Don't skip the nutmeg — it's what makes it taste like proper Alfredo. Also, don't you dare use pre-shredded cheese; it won't melt right and you'll regret it. I once used broken-up lasagna sheets and they clumped like crazy — now I use mafalda or broken pappardelle and it's so much better. If you want a little heat, add red pepper flakes at the end. This soup thickens as it sits, so add a splash of broth when reheating. It's even better the next day, if it lasts that long.
