The simple healthy recipe is also gluten free, nut free, sugar free, egg free, whole30, paleo, keto friendly, and soy free.

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!

    Katie, this recipe was genius! I have been enjoying your desserts for a while but was nervous to try other dishes. But I just got diagnosed with a dairy allergy…and I LOVE cheese. This cauliflower alfredo recipe is one of the best alfredo recipes I have ever had!

    I made it using almond milk, Earth Balance buttery spread, vegan mozzarella cheese shreds, and a blend of dried basil, oregano, paprika, red pepper flakes, & black pepper. I stirred in the “cheese” after it was all blended & off the heat. (This also allowed me to put real 1/4 cup parmesan in my husband’s & 1/4 fake cheese in mine.) It was divine. My husband had no idea it wasn’t regular alfredo. He was shocked when I told him it had cauliflower as the main ingredient!

    I’m here looking for healthy cauliflower recipes. This looks genius–I’m also checking out the Mac ‘n Cheese–but I’m absentminded and worried about cooking the cauliflower in milk long enough to make it soft without burning it. I’m not crazy about adding raw onions into the mix either. I’m going to have to play with this. You’ve got two T. of fat here. I might try microwaving the garlic and vegetables first to get them started. Sauté them in the butter/olive oil? Steam the cauliflower first? Then add it to the onion and garlic? Wish me luck.

    I have to remind myself that when I eat it that it’s not loaded with butter and cream, it tastes so rich! I used nutritional yeast, pepper, and 1 tsp oregano, and put it over pasta with sauteed zucchini, mushrooms, and onions; the result was absolutely delicious. Leftovers were great too, this one is definitely a keeper.

    Please add me to the throng of those who totally flipped for what you’ve shared. I went full on dairy, using whole milk and the Mozzarella…I also included the optional Onion. Clearly the easiest pasta sauce to make in advance ever! When preparing the dish for serving I went full on decadence…6 oz. pasta was slathered/tossed in all of the sauce, and I plated for 2. I suppose a little of the sauce remained in the pot. We loved the flavor and this will become a mainstay. I’ll try not to think of this as a “healthy” entree….more fun to think it was rich and seductive. Thank you for sharing!

    This recipe is awesome! To me it tasted just like a cashew sauce, but it’s way more affordable. I want to make cashew creamy sauces all the time but the nut is just so expensive. This is a great alternative! I used nutritional yeast. Thanks, Katie!

  6. Natalie says

    This was so good! I love alfredo sauce but i always feel awful after having it so this was the perfect guilt free meal. I went ahead and halved the recipe to make a smaller serving, although it is still more than enough for two people! I will say that it is not as smooth as regular alfredo but that might be due in part to my immersion blender. I also used bigger chunks of cauliflower so it took considerably longer than 15 minutes, turned out great in the end though!
