Cauliflower Alfredo (Vegan & Nut-free)

This post may contain affiliate links. Please read my disclosure and privacy policy.

This Cauliflower Alfredo Sauce is creamy and delicious, while being deceptively simple! In lieu of the heavy cream, butter and cheese found in traditional Alfredo sauce, this particular version gets its creamy texture from pureed cauliflower— but when you serve it, most people can’t even tell.

This sauce is naturally Vegan and Paleo-friendly, but make sure to choose a pasta that also fits your dietary needs by looking at the label. Zucchini noodles make a great grain-free option!

Benefits of Cauliflower

Cauliflower is the ultimate “chameleon” of vegetables, if you ask me. It can easily transform into Cauliflower Fried Rice, Cauliflower Pizza Crust, or a creamy sauce, like this one. Cauliflower also hides well in a Low-Sugar Smoothie, if you’re trying to use a little less fruit.

Here are some of the nutritional benefits of cauliflower:

  • There are 3 grams of fiber in just 1 cup of cauliflower. (That’s 10% of your daily needs!)
  • Cauliflower is high in antioxidants and flavonoids, which may help to lower the risk of cancer and heart disease. (source)
  • 92% of cauliflower is water, and eating water-rich foods have been shown to aid in weight loss.
  • Cauliflower is high in choline, which is involved in brain development and a healthy metabolism.

How to Make Cauliflower Alfredo Sauce

Making this Cauliflower Alfredo is as easy as steaming fresh or frozen cauliflower until tender, and then blending it until smooth with the rest of the ingredients. The key to this sauce is slightly over-cooking the cauliflower, so that it’s very soft and easily blended.

In situations like this, I’m not concerned with losing a few nutrients by over-cooking, because the true benefit of eating this sauce is that it’s replacing the heavier version.

By avoiding the whipping cream, butter and cheese found in traditional Fettuccine Alfredo, you’ll be doing your body a favor every time you choose this sauce, instead! Your taste buds will be pretty happy, too.

This low-fat creamy sauce is dairy-free and nut-free, making it the perfect topping for your favorite pasta or vegetables. I could see it being delicious in a homemade lasagna, or even over a white pizza, too! The options are endless. If you follow food combining principles, this sauce is “neutral” and can be served with any other foods you like for streamlined digestion.

Prep Time 10 minutes
Cook Time 20 minutes
Total Time 30 minutes
Servings 2
Calories 64kcal


  • 1 teaspoon extra virgin olive oil
  • 2 cloves garlic , minced
  • 12 ounces cauliflower florets (about 3 cups)
  • 1 cup water
  • 1/2 teaspoon fine Himalayan salt , or more to taste
  • black pepper , to taste


  • Saute the minced garlic in the oil in a small saucepan over low heat. Allow to cook for a few minutes, until the garlic is tender and fragrant, but not browned.
  • Add the 1 cup of water to the saucepan, along with the cauliflower, and bring the water to a boil. (The water will not cover the cauliflower, and that's okay.) Once the water is boiling, lower the heat to a simmer and cover the pot to cook until the cauliflower is fork-tender and very soft, about 10 to 15 minutes.
  • Transfer the entire contents of the saucepan into a blender or food processor, and season with salt and pepper. Process until very smooth and creamy, with a texture similar to traditional cream sauce. (Always be careful when blending hot liquids-- the steam pressure can blow the lid off your blender. Cover the vent in your blender lid with a thin kitchen towel to allow venting.)
  • Season with additional salt and pepper, if desired, and serve hot over your favorite pasta.



Keep in mind that this sauce will need additional salt if served over plain pasta or steamed vegetables, as the flavor will get diluted. If you plan on adding another salt source, such as Parmesan cheese, the additional salt may not be necessary.

This sauce is delicious on its own, but it can be extra-tasty with a few add-ins. A few ideas are listed below, but feel free to get creative!

Optional Add-Ins:

  • Nutritional yeast, for a dairy-free “cheesy” flavor.

i made this for dinner tonight and it was a big hit! it got a solid “a” among young and old. I love the fact it only has a teaspoon of oil, adding very little fat to the dish. i added a pinch of nutmeg as well as a couple TABLESPOON of nutritional yeast flakes, garnished with fresh basil and served over gluten free penne. definitely a keeper.


WOWWWWW! This is delicious! As a new mom I am in need of food that I can prepare fast and is also healthy. My one year old throws any veggies off his plate so this is perfect way to get his veggies in. Do you think this sauce would freeze well?

    Maureen Cram

    I have frozen it and it tasted great when I thawed it out. I made double so I could freeze some and save on washing pots!


I’ve made this and could eat it with a spoon! It’s very easy to make and only takes a few minutes.
I’m thinking about adding some chickpea miso (I don’t do soy or nutritional yeast) for a cheesier flavor. How much should I add? 1/4 cup maybe?

I absolutely loved this! I served it only over a mountain of steamed veggies and it was so Delicious! I cant wait to have the leftovers tomorrow!

Michael Kleinman

I am all for new recipes with cauliflower and personally make Cauliflower rice, cauliflower hummus and Cauliflower pizza crust. I take issue with the idea that butter, heavy cream and parmesan cheese are unhealthy. That is old thinking that has been debunked by current science and even the government has remcinded their guide lines on eating these products and claim their is no evidence that they cause harm. The carbs in the pasta you put the sauce on is the real health risk.

    Angie W

    I agree. Just wish with my son’s diagnosis we could still eat them!!


Hi, I like your blog! I just wanted let you know that you misleading people by telling that this diet is optional for candida. People on diet can eat pasta.

Angie W

My son is on a milk elimination diet for EOE. I’ve been trying to find easy things that and 11 year old who’s been eating “regular” food would like. This is amazing. And mind you, I was super skeptical. I don’t just want a substitute! I want stuff that tastes good enough to want it as well or instead. I did add onions, almond milk to thin it a bit, mushrooms, a bit of mustard and nutritional yeast. I was shocked!! Thanks!!

    Megan Gilmore

    I’m so happy to hear that you enjoyed it! Thanks for your comment. 🙂


Delicious! I added the recommended nooch (1 tbsp) and 1/4 cup of pine nuts before blending. Will be enjoyed again in my home for sure!


I used cauliflower rice as that’s what I had on hand, and adjusted the water content. Just as tasty. I also don’t eat dairy so used my vegan Parmesan – nutritional yeast, cashews and a little salt – for those who don’t have nut allergies. Worked a treat!


how much nutritional yeast would you suggest could be added to this recipe? I cannot wait to try this! 😀


Just tried out this recipe, and it was amazing! I skipped the oil/butter and added the suggested nutritional yeast for a more cheesy flavor. It was delicious and surprisingly filling!


Can you use cauliflower rice or does it beed to be florets?

Amanda Broome

In response to S.R.’s post awhile back of still tasting the sulphur flavor that comes with cooked cauliflower- and anothers question of other vegetables to use, I might have a solution for both in a recipe I tried from a different website. As for cauliflower flavor use cooking process described next. Use Zucchini. Make sure to peel all green off and if older zuke de-seed before chunking and cooking in water- boil twice and throw away water away both times to make flavor milder. When blending/pureeing flavor any liquid used in recipe or thinning to thickness desired- ie… milk or a safe bouillon in water or noodle cooking water, nutritional yeast perhaps even a mild white miso or parmesan if allowed


Does this freeze well?

    Megan Gilmore

    I haven’t tried it, but most sauces do freeze well! I like to freeze in ice cube trays for easier reheating later.


Has anyone tried to freeze this sauce?


Can you use frozen cauliflower?


DELICIOUS! added extra garlic and nutritional yeast, and sauteed freah minced onion and 1 tbsp avacodo oil…soooo good!!!


Just made this and it was amazing! I cooked the cauliflower in chicken broth and added a pinch of nutmeg and some lemon. Topped it with some cilantro and sundried tomatoes. Thanks so much for providing us with comfort food that is guilt-free and dairy free :))

p.s. your date energy balls are also a favorite dessert of mine!


Oh my goodness. This was amazing!!! I made it tonight for my husband who loves alfredo and he was just as crazy about it as I was. I mixed it with chickpea pasta and steamed broccoli, topped it with mozzarella and broiled it for a bit. So so so yummy!


This was amazing! I took it down a notch and made it even easier and put garlic in a bowl of water and microwaved it! Then added the cauliflower for about 6-8 minutes. I didn’t even add the nutritional yeast and it was fantastic!!! (added salt and pepper and that was it!) Yum!


Can someone tell me if there are tiny “pieces” of cauliflower in their finished product? This didn’t get as creamy as I’d hoped and I didn’t know if it was the way the recipe was or did I not cook the cauliflower enough? Def was not of the consistency to fool anyone that it was actual Alfredo. Ended up using it to make mashed potatoes with instant flakes, flavor was yummy.

    Megan Gilmore

    No, there definitely shouldn’t be any pieces of cauliflower in there! Sounds like you need to cook it longer so that it’s mushy-soft, and blend it until silky smooth.


Made this and ate over zucchini spirals sauteed in garlic and onion with turkey sage meatballs on top!. DELICIOUS! Thank you for the recipe.

Nancy R

Thank you for making this nut free !! Im always aiming to eat healthy and mostly plant based. My husband has nut allergies so i greatly appreciate nut free recipes.


I made the Cauliflower Alfredo tonight for dinner. I’m a vegan, occasionally eat seafood. My husband is a dairy meat lover. He absolutely loved dinner tonight. I did add shrimp, sundries tomatoes, fresh spinach and nutritional yeast


I just love Cauliflower and all dishes containing it. I also like how you described in great detail how to prepare this delicious sauce.

Sherry Boxall

Im pretty sure you are a genius… thx for the inspiration!


This was great! I adapted it a bit and added sautéed onions & garlic, lactose free milk, paprika, onion & garlic powder to the steamed cauliflower, and then blended it all up for a creamy sauce. I cooked it a bit longer in a skillet and it turned put so delicious.

Hannah Lemon

This was really good and very easy to make! I’m out of nooch but I’m sure it would taste even better with that added. I made vegan pasta from scratch and added some frozen kale and basil from my garden, as well as a bit of paprika for a little spice.


I was a skeptic about this I have to say!! How can cauliflower reeaaaallly be a smooth sauce? I was shocked. This was such a tasty recipe. Now it doesnt taste thick and gluttonous like alfredo sauce does, and that’s what I liked about it. Thanks for the great recipe!


Thank you! This was even better than I’d hoped 🙂


This is sooooo good!


Wow! Wasn’t expecting much at all but this is an awesome base recipe for all kinds of sinful foods!! I even messed it up a little (running around after a 2 yr old) and it was really good. I’m thinking about experimenting with carbonara sauce and moussaka using this.


Thanks! I enjoyed this quite a bit. Added some fresh basil into the blender with the sauce. Made it a little green so I guess just sprinkling it over top would have been better. I also added a bunch of other veggies on the side and smothered them in the sauce along with quinoa noodles. Pretty tasty! Even my carnivore husband said he liked it though he added a fair bit of parm. Anyway, thanks again!


This was great! I doubled the recipe for about 12 oz of pasta and added peas. My alfredo-loving husband said he didn’t think he’d like it, but admitted that it tasted good! My 14-month old loved it!!


The cauliflower Alfredo was amazing thank you so much 😊


Thank you for coming up with a recipe that is nut-free! Can’t wait to try this!


I just made it and this was fantastic! My husband couldn’t believe this was just cauliflower! I love how simple it was, thank you so much <3

Of course adding cheese was essential because otherwise it's a bit bland, but if you are vegan, you can always just add dairy-free cheese 🙂

Thank you again for this recipe.

Linda Cohen

Wow! I made the Cauliflower Alfredo for some mushroom crepes, all vegan and Passover approved and it was great! the sauce was creamy and smooth and yummy! ( I left out the nutritional yeast because of the holiday, but will try it again after).Thank you for the easy and delicious recipe.


The 5ime stated and the times listed in the method do not add up. This IS the worst thing for finding recipes. Seriously, not cool.


This recipe was absolutely delicious. It was so creamy yet fluffy and light, it paired lovely with tomato basil sauce and some spinach I seasoned with garlic, lemon juice, and salt + pepper! It’s perfect for a vegan diet.


I am wondering if you could use cauliflower rice to make this instead of the whole cauliflower?. Would you just sauce it first & then put it in the blender fpllowing the recipe from there? Thanks.


I added some spinach and more salt for flavor. I don’t think this tastes like Alfredo but I do think it’s a great way to get in more veggies. How long does the sauce last in the fridge?


Great recipe! I added about a cup of unsweetened coconut milk to make it creamier. The nutritional yeast made it perfect! Served alongside roasted broccolini . Delicious!

Jennifer Haden

This sounds great, would love to try this. Can i substitute frozen cauliflower for the fresh?


Can’t believe how something so simple tasted to creamy and delicious. Thank you for this wonderful recipe!

David Johnson

Eight ounces pasta with a bit of chopped red and green bell peppers for color, two tablespoons full of nutritional yeast in the Alfredo, vegan Parmesan, then chopped parsley leaves. Presto: Pasta Alfredo cavolfiore, since you don’t tell a fourteen year old he’s enjoying cauliflower until after his second helping. Sorry not to be able to post a picture, but it looked as good as it tasted.


Yum…I added Nutritional yeast and easily doubled the fresh cracked Pepper. I mixed with a hearty pasta and added roasted veggies.


I was very skeptical about this recipe, but after reading the positive comments I decided to give it a go. I added sliced baby Bella mushrooms to the pasta while it was boiling. I also added thinly sliced sun dried tomatoes and sliced fresh basil to the sauce. It was AMAZING! It was creamy and delicious. And, NO cauliflower taste. This is going in our rotation for an easy and delicious meat free dinner.Thanks so much!!!
