Recipe Highlights

I don’t know about you, but I’ve been craving more and more comfort foods lately. It’s just been that kind of year! And, a bowl of gluten-free pasta smothered in a creamy sauce does the trick.

Fortunately, this Vegan Cauliflower Cashew Sauce recipe is actually healthy and hides a serving of vegetables. You can barely taste the cauliflower in this dish. It is:

  • dairy-free,
  • vegan,
  • easy to throw together,
  • and includes a serving of cooked cauliflower.

Both kids and picky-eaters love this upgraded version of Alfredo sauce. Skip the heavy cream and use cauliflower instead. Let me show you how to make it!

Recipe Steps

cauliflower and cashews

Step One

The first step is to soak your cashews and steam your cauliflower.

You can either steam your florets on the stovetop, or you can cook them in the pressure cooker (see my Instant Pot Cauliflower recipe).

Step Two

Next, you just need to combine the cooked cauliflower, cashews, nutritional yeast, and other ingredients in a high-speed blender like a Blendtec or a Vitamix.

Step Three

Blend the ingredients for about 45-60 seconds until you get a super creamy sauce.

Step Four

Next, it’s time to serve your sauce! I like to pour it over cooked pasta (see the best gluten-free pasta brands), and eat it right out of the bowl.

This recipe makes a big batch of the sauce, so you can use half of it right away, and then refrigerate or freeze the other half. Or, if you are serving this to a large family, then you might be able to eat it all in one go.


What if I don’t have nutritional yeast?

You can leave it out! It adds some flavor, but not too much.

Can I use roasted cashews?

Yes, but raw cashews are generally softer and easier to blend.

Can I make this recipe nut-free?

Yes! You can use hemp seeds or sunflower seeds instead of cashews.
