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!

This strikes me as one of those “it’s just so crazy it may work” recipes! I’m a total alfredo fiend so I can’t wait to try this.
I’m an alfredo snob. I’m picky because I want it to taste awesome every time because I don’t have it often at all. I tried this last night and can completely see me converting to this recipe.
I wish I could post a video to show how thick and creamy this got! I used fat free evaporated milk, with a little bit of skim to get it up to 2 cups; and only 2 TB of butter though I doubled everything else. Thanks!
As a kid alfredo sauce scared me beyond all reason, but as a adult, I learned to love it. Soon it will be cauliflower picking time so going to hold this recipe nearby and give it a try!
Woaa! This is such a cool idea 😀 Such a sneaky way for my moms to add in some veggies to their kid’s meals too 😛
Totally making this tonight for my little flying purple picky eaters!! They aren’t to keen on veggies. I have hope for the baby, though, he seems to prefer vegetable purees! Wish me luck!
I love using cauliflower to make cream sauces! Why add unnecessary fat and calories when you can have a veggie instead, am I right?
because fat can make a meal satisfying, and richer. That being said, I don’t think that we should drop in a stick of butter, but I think that a little fat adds a little more flavor and richness to a dish, and it makes it more satiating. Veggies are good and all, but when they replace every indulgence in our diet, it’s a sad thing. I’m not trying to condemn this recipe, I’m just trying to answer your question “Why add unnecessary fat and calories.” It could also be to gain weight if you are underweight
I think you took my compliment as a genuine question. I’m NOT underweight, so I appreciate not adding fat to a recipe if I dont have to. I haven’t tried this version yet, but the versions I have tried have been plenty rich and I don’t really find fat satisfying (fatty foods definitely give me heartburn, nothing satisfying about that!). If you’re looking for fatty foods, I’m not sure Katie’s blog is the best place to find them.
I’m sorry, I’m really partial towards fat. I could eat about 2 cups of nuts a day, and I feel that they are the only foods that will satisfy me if I’m hungry.
I’m sorry, but your comment sounds a tad ridiculous to me! “I’m sorry, I’m really partial towards fat” – do you realise you are on a site that offers amazing meals, tweaked so they may be a little healthier?! Thus making your comments completely out of place.
I understand you like nuts, but nuts are good fats, another odd comment. And when a recipe seems high in fat, you are best looking into the ingredients as they may be amazing healthy foods that are bringing up the fat content.
Clearly Kelly was asking a rhetorical question, and a good one at that, on such a site. 😉
I am probably being a hypocrite here, but I’d suggest you don’t comment when you clearly have nothing useful to say.
Trajayjay was simply explaining why some fat is necessary and welcome in many healthy dishes, so I can’t understand the nasty comment. Eating fat doesn’t make one fat. Carbs are the true devil. As a person with type 1 diabetes, I test my blood 10-12 times a day and can tell you that carbs affect blood sugar negatively, while fat doesn’t. For many of us, to eat a healthy diet requires very few carbs and a much higher ratio of fat.
Perhaps that is correct for Type I diabetes (I cannot say because I never studied it), but for Type II and any other person around, fat clogs arteries and puts weight on. There are 70 years of research which shows that countries who eat carbs such as rice, corn and grains as a main part of their diets have less heart disease, osteoporosis or diabetes. Dr. McDougall has articles showing that fat is a worse culprit than sugar in Type II diabetes.
Children in our country have striations of fat around their aortas at 3 years of age. Any way to cut fat is good for health.
I put here some articles about Type 1 diabetes just to look at. I know Dr. McDougall often describes how medicines are increased due to how doctors handle illnesses. Again, such a serious condition as Diabetes 1 is something I don’t know much about, but I always like to show what different evidence is out there for people to check out and make decisions on their own.

A lot of Katie’s recipes are high in fat. The fudge babies and the Samoa’s pie are two examples
I think that it is common to crave fats. And while I think this recipe looks delicious and is much healthier I think what was trying to be said before was just that even a small amount of fat can add richness that we crave. Enough to help us keep our on a “diet”. I think if you decide to eat healthy and you way restrict yourself too much you will eventually cave. If you find a way to combine healthy foods with just a small amount of fat, just enough to trick our bodies into being satisfied wih it then we can be much more successful in our healthy eating goals. Im not saying eat stick of butter a day. Just that if you compare regualr alfredo to a cauliflower alfredo with maybe just a tablespoon of butter will be satisfying while still cutting the calorie ajd fat count way down compared to alfredo with a roux and cream.
Can I just say to EVERYONE that there’s NO DEMON food group.
The human body needs every single food group in order to be healthy healthy
The only problem is when people either consume a too high proportion of one particular food group thus neglecting the others.
Being overweight is caused by consuming too many calories.
You could eat zero fat or zero carbs and eat all the finest proteins and vegetable and fruits and still be overweight if you are eating too many calories, regardless of their source.
Yes, you do need a smaller percentage of certain food groups, which is illustrated on such diagrams as the familiar picture of a plate which is pie chart for the different food groups but you should never cut any one group out UNLESS you have a medical condition such as diabetes etc which you need to control with a modified diet.
Also, being a normal weight (bmi) does NOT mean you are guaranteed to be healthy. you can eat appalling diet and not get overweight if you don’t eat over your calorie requirements.
Also numerous studies and medical evidence is now able to show how fat can gather around your organs whilst remaining invisible to the eye. ‘Skinny’ people can be ‘fat inside’
Eat every thing in moderation and you will reduce cravings which are responsible for the common diet blues and frequently end up in someone binging on masses of food because their body is confused and craving what it has been denied. .
Do you put the nutritional yeast in at beginning? I want to try this tonight!
Yes 🙂
The olive oil and/or vegan butter is healthy fat in the recipe… I believe in eating healthy fats… I agree with trying to avoid unhealthy fats such as in a normal mac n cheese recipe. LOVE This recipe!!!
Not to be contrary, but most vegan butter will be composed of damaged polyunsaturated fats. for everyone out there, grassfed butters an amazing nutrient dense food! Enjoy the real thing! http://realfoodliz.com/why-ghee-is-good-for-you-inside-and-out/
How do they feed grass to butter? No need to promote a non vegan product here; the milk from a cow is meant for their babies, it’s not mean to be stolen by humans to make butter. These great recipes here don’t need it either.
I’d like to know if it’s possible to make just as creamy without oil. I made an Alfredo sauce with tofu once but whatever else was in it wasn’t enough flavor.
Ohh I might try your vegan version, or maybe this one just on spaghetti squash!
We must have gotten your good weather by mistake here in Canada! Its like we skipped Spring over here and went straight to summer!
Right? Here in Northern BC it was over 25° C (around 80°F for those in the states) and wonderfully sunny the past three days. Today it isn’t quite as warm, but I’ll take it considering our last snowfall of the year where I am is May long weekend!
Wow! That’s crazy for BC! Isn’t that pretty much as warm as it ever gets out that way?
The warmest it gets where I’m from is around 30°. Last summer the warmest day was 32°, and that was in July! During the summer it’s usually about 25° though, just not in May!
This looks so yummy!
How creative! I would never have thought to try something like this. I just bought nutritional yeast a few days ago for the first time- I will have to try this recipe. 🙂
Oh yum! Alfredo was one of my guilty pleasures as a kid, but you know it’s not the healthiest. I haven’t had it in foreverrrr. I bet this would be amazing with a little cashew butter added too for some added creaminess (instead of the butter). Yep, we’ve been hit with super hot weather! I love it.
Can this be made with frozen cauliflower?
I’ve never actually tried.
I made it with frozen cauliflower and broccoli and it was nice. There is lots of extra water in frozen caulis for some reason so keep that in mind.
I made this last night with frozen cauliflower and it turned out awesome! I just let it sit out to thaw first and made it like normal. I 3x the recipe and also added a cup of Parmesan after blending, it added a lot of flavor. This recipe is a keeper for sure!!
Even LA is getting hit with some cold(er) weather. We’ve had a few warm days, but this morning it’s been raining on and off! Love this recipe. It’s the best when you can throw everything into one pot!
This looks incredible! Cauliflower and its infinite possibilities.
Oh my goodness! Yum, yum, YUM!!! You’re always creating the BEST recipes ever, Katie! I bet my picky older (yes OLDER) sister would even like this! YAY!!! Thanks AGAIN Katie!!! 😀
What, Texas got hit by the weird weather, too? I’m in Des Moines, Iowa, and two Sundays ago, I got sunburned and miserable during a half marathon, only to encounter inches of snowfall over Thursday-Friday. It’s nice now … crossing my fingers that we’ve turned the corner. Oh yeah, and the alfredo sauce looks delish and easy!
Katie, this looks great! I’m definitely going to make it soon. It’s funny you bring up the pumpkin recipes and feeling wintry. I’ve definitely been in an autumn state of mind. I even have a cinnamon and cranberry cake baking in my oven as I type this haha.
