pasta in a bowl with broccoli and cauliflower sauce

Cauliflower Alfredo Sauce is a great low carb alternative to regular Alfredo sauce. It’s easy to make and very flavorful!

Cauliflower is still a hot and trendy topic. I thought cauliflower pizza and pasta died back in 2015 but according to my poll on Instagram this week everyone is still excited it about all things cauliflower!

Don’t get me wrong, I love cauliflower just as much as you do!!! And sometimes, something lightened up like this cauliflower Alfredo sauce just sounds sooo good!

This sauce is:

  • Easy to make – only takes a food processor or blender!
  • Healthy and nutrient rich
  • Low carb
  • Easily whipped up in 20 minutes
  • Versatile

This sauce has the perfect creaminess and is easily whipped up in 20 minutes!

You’ll need a food processor or a powerful blender to blend up all of the cauliflower once the cauliflower is boiled. Then everything will be combined together in and the sauce is DONE.

I paired my sauce with broccoli and linguini and it was a delicious weeknight dinner. You can make this into chicken Alfredo, Alfredo flatbreads, or even make a Chicken Alfredo pot pie mmmm!

Next time you buy a head of cauliflower try out this recipe – you won’t regret it!! 🙂
