This vegan alfredo sauce is simply the best. It’s made in only 3 minutes in a blender and is ultra-rich, creamy, cheesy, and nutty, too. This recipe is “Is this really vegan?” material!
This unbelievably creamy, rich alfredo sauce tastes so much like the real deal, but with no dairy or other animal byproducts. It’s so quick and easy to make, too, making it perfect for an easy weeknight dinner. With a few secret ingredients that make this alfredo sauce the absolute best, you may never go back to the traditional kind!
What Makes This Recipe So Good
Cashews – Cashews make this sauce ultra creamy and buttery, making the sauce nice and thick, but not too thick.
Nutritional yeast – Adds a nice cheesy flavor.
Tahini – Made from toasted ground hulled sesame, tahini adds a lovely nutty flavor that mimics parmesan cheese.
How To Make It
Soak the raw cashews in hot water. I pour hot water over mine and let them sit for 30-60 minutes while I do other things. (This is optional but helps positively ensure a smooth sauce.
Drain the cashews and add to a high-speed blender along with other ingredients, and blend on high speed. (See the top tips if you don’t have a high-speed blender!)
Toss with the hot, cooked pasta and serve!
Chef’s Tips
- If you don’t have a high-speed blender, you MUST soak your cashews in hot water for several hours. Otherwise your sauce will not get the right consistency!
- Reserve a little of your pasta water and add it to your alfredo a tablespoon at a time to help thin the sauce and help it cling to the noodles.

I really liked this recipe and changed a couple of things by adding fresh basil, portabella mushrooms and an orange bell pepper sauteed. I was a little short on the lemon, so I added a little pinot grigio wine to sauce. It turned out delicious on penne pasta. 🙂
Yum, that sounds delicious, Cameron!
Can I substitute Oatmilk for almond milk? I only have vanilla sugar free almond milk. I have extra creamy Oatmilk.
That should be ok!
Delicious! This is my go to vegan Alfredo sauce recipe. I use a food processor since I do not have high powered blender. I soak cashews in boiling water and leave the in processor for a long time to reduce the grit.
That’s perfect! So happy you love this alfredo sauce, Sarah – thank you for the kind review!
I’m not even vegan but I like to avoid dairy and this sauce is SO GOOD. My husband and I found this a while back and always go back to it when we want Alfredo.
That’s wonderful, so glad you love it!
Nice. Are the nutritional facts just based on the Alfredo sauce or the whole meal? Also how much is 1 serving?
Thanks! Looks delish.
The nutritional facts are based on one serving. The average serving size is about 2 cups including the pasta.
Tahini is not in the instructions. My guess is it goes in the blender with everything else? This may be dinner tonight😉
It’s in the second step! Add it with the milk and most everything else.
