Vegan cashew and cauliflower alfredo sauce

Jump to Recipe Print Recipe

Rich, creamy and delicious, this vegan cashew and cauliflower alfredo sauce will not disappoint. Plus it’s full of nutritious ingredients, making it a great healthy choice for dinner.

What's your favourite vegan pasta sauce recipe?

While I do love a veg packed sauce, I'm also rather partial to a simple tomato one (especially in summer) or a vegan pesto.

But I also love this creamy vegan Alfredo sauce. Made with roasted cauliflower, creamy cashews and almond milk, with a little nutritional yeast added for flavour and vitamins, it really hits the spot in terms of flavour. Plus it's extra creamy to boot.

What is Alfredo sauce?

In Italy Alfredo sauce or Fettucine Alfredo is simply pasta served with Parmesan cheese and butter. It was invented by Alfredo di Lelio in Rome in the early 20th century. The dish spread to the United States and ingredients in an Alfredo sauce there often include cream, garlic and herbs.

Alfredo sauce is traditionally served with fettucine, a long flat pasta shape. I often use spaghetti instead as it's much easier to find where I live.

How to make vegan Alfredo sauce

There are various ways that you can make vegan Alfredo sauce.

In theory you could make a simple version with dairy free spread and vegan Parmesan cheese. Most recipes are a little more complex though and many call for a sauce made with cashew nuts or cauliflower. In my recipe I've combined both for maximum nutritional value and flavour.

I sometimes roast extra cauliflower and serve it whole with the sauce - this makes it extra delicious and I really urge you to try it. Roasted cauliflower is a real game changer.

How to make cauliflower Alfredo sauce

I first had a cauliflower Alfredo sauce when I made this delicious recipe by Kellie's Food to Glow, which uses sunflower seeds instead of cashews - great if you're trying to keep costs down. I've made Kellie's recipe several times now and it's gradually changed into my own version. I hope you love it as much as we do.

    What a fantastic and healthy sounding pasta sauce. Such a clever idea to use those ingredients to come up with a vegan alfredo sauce.

      Thanks for commenting Cat - this really tastes great and is a lot healthier than a traditional alfredo sauce as well x

    I love how creamy the sauce looks and I bet the cauliflower adds such a great flavour.
