While most skinny Alfredo recipes call for cashews, tofu, or coconut milk to replace heavy cream, this sauce can also be made without any of those ingredients.
Instead it gets its creaminess thanks to the nutrition superstar cauliflower.
If you’ve never tried thickening a sauce with cauliflower, I highly recommend it.
You get a rich and creamy sauce without all the extra fat and cholesterol, and it sneaks in a vegetable serving you won’t even know you’re eating!

I am hooked! Used this Alfredo sauce to make veg au gratin. Added a bit of wheat flour to the sauce and the texture was to die for!
Never going back to cream or all purpose flour.
This is the best Alfredo I have ever eaten. Thank you! We have switched to a plant based diet and miss some of our favorites. I sautéed the shallot, garlic & cauliflower before added oat milk. Once the cauliflower was soft, I pureed everything and added the nutritional yeast, lemon juice, dijon mustard, s&p. My 3 1/2 year old granddaughter LOVED it. The whole family said keep this one on the rotation!
This made us so happy to read 🙂
I’m about to try this. What milk did people find worked best (non dairy). Thanks!
An unsweetened milk works well. Something like almond, cashew, or macadamia. Or for a richer version, canned coconut milk also works.
Thanks. I ended up using oat milk. It was great! Thanks again!!
Great idea!
Having just gone vegan a little over a month ago and eating smoothies and bland veggies, I had to try this. Well I’ve made it twice just this week alone LOL!! It’s like crack; I just can’t get enough!! I did not even add nutritional yeast and happy to say it doesn’t need it! Zucchini will never be the same again! Thank you, thank you, thank you Katie!
I could not believe how good and easy this was! Definitely making this my go to Alfredo sauce!! ❤️
Made this yesterday to use as the base of a breakfast pizza. I did use cheddar cheese and I used a mix of buttermilk and chicken broth, plus a good squeeze of dijon. SO FREAKING GOOD and could not be easier. I plan on using part of the rest of it tonight (I made a big batch) as a sauce for tortellini and broccoli. I am using the rest of it later this week to make a spinach artichoke dip! Its fabulous.
So delicious!
I was intrigued by this : cauliflower that would double as alfredo sauce so I made it recently. I served it to my family with real linguine noodles, added shrimp and they loved it. A good size head of cauliflower is all you need! I have the leftovers in refrig. and have been using them on vegetables all week. Very tasty and once you get the hang of the recipe, it goes fast. I did find that I needed to use a blender to really blend this mixture into a smooth alfredo sauce. I used both the mozzarella and nutritional yeast for the flavoring. Wonderful!! everyone should try it, it does not taste like a veggie at all!!!
Thank you so much for trying it!
I’ll make this sauce again but I will start with 1/4 c nutritional yeast. It was a quick, easy recipe to pour over my vegan cowgirl steak with cauliflower mash side dish.
