Light Fettuccine Alfredo

This Light Fettuccine Alfredo is creamy, cheesy, and so good. The best part is it only takes 15 minutes to make from scratch. Pair this lightened-up sauce with pasta and your choice of shrimp or grilled chicken for an easy and healthy weeknight dinner.

If you’ve ever ordered Fettuccini Alfredo at restaurants you know just how creamy and rich it is. I made the mistake of looking at the nutrition one time… oh man. I thought “Well, that’s why it tastes so good,” restaurants add heaps of butter, heavy cream, and parmesan cheese to make alfredo sauce.

This lighter version has about half the butter and replaces a lot of the heavy cream with low-fat milk. All the flavor is still there but with half the calories.

Do you have questions?

What makes this sauce “light”?

I reduced the amount of butter by half and swapped out a lot of the heavy cream for milk. All of the flavor is still there, but you won’t feel so full after.

How much pasta should I make for this sauce?

There is enough sauce to generously cover about ¾ pounds of dry pasta ( ¾ of a 16oz box of pasta).

Watch how it’s made…
