This easy vegan alfredo pasta sauce is finger-licking delicious and uses just a few common pantry staples. Even though it's dairy free, it's enjoyed by vegans and non-vegans alike!
Conventional alfredo sauce
Traditional alfredo sauce consists of butter, cheese and sometimes cream. Basically the most un-vegan ingredients you can think of!
If you wanna be REAL, I associate alfredo pasta with a convenient packet mix. All you need to do is pour, stir and heat. As a child, I used to inhale alfredo pasta soo quickly that I'd get indigestion.
This recipe for vegan alfredo is on par with all my childhood memories.
What does vegan alfredo pasta taste like?
I was sceptical about how vegan alfredo would taste. However, I was so extremely surprised when I first made it. This alfredo sauce is:
- CREAMY and smooth
- Hard to stop at one bite
- Easy to make
Simple ingredients you'll need
Raw cashews provide an excellent base for the sauce as they have a subtle flavour and provide a satiating creaminess and fattiness.
The onion and garlic impart a fragrant umami flavor in the vegan alfredo sauce. If you don't have fresh onion and garlic, you can use powdered onion and garlic.
Nutritional yeast adds a touch of cheesiness and dose of B12 that all vegans need!
Plant-based milk gives the sauce moisture and that slurpy goodness.
Salt adds flavour to the alfredo sauce and brings out the flavour of the onion and garlic.
A complete list of ingredients, quantities and instructions are in the gray recipe card at the bottom of this post.
How to make vegan alfredo pasta sauce
All you need to do is:
- Soak the cashews in hot water.
- Saute the onion and garlic.
- Drain the cashews. Add all the sauce ingredients into a high-powered blender.
- Blend until smooth and mix with the cooked pasta!
With the help of a high-powered blender, you can make whole cashews into a decadent creamy sauce.
It's simple, easy and quick!
Customising the vegan alfredo sauce
I sauteed some mushrooms and spinach and added them to my pasta. They are delicious and a sneaky way to get in more vegetables!
You can bulk up your pasta with other ingredients such as:
- Sun-dried tomatoes
- Roasted tomatoes, eggplant or zuchinni
- Pine nuts
If you'd like a cheesier sauce, feel free to add ¼ cup of grated vegan cheese.
Or you can give the sauce a whole new flavour! When you put the sauce ingredients in the blender, you can also add:
- Basil for an alfredo pesto sauce. Or check out my Basil Alfredo Pasta recipe.
- Roasted capsicum
- Roasted tomatoes

I've used spaghetti, fettuccine and basically all types of pasta for this alfredo recipe and they all worked really well!
Here are a few examples of what you can use
- Any short pasta such as macaroni
- Wholegrain pasta
- Gluten-free pasta
- Zuchinni noodles (zoodles)
