The Best Vegan Alfredo Sauce Recipe

I’m so excited about this alfredo sauce recipe that I don’t even know where to start. It’s a vegan alfredo sauce. A dairy-free alfredo sauce. And a deliciously rich and creamy alfredo sauce that you’ll love even if you’re not vegan or dairy-free. Are you with me?

I’m not vegan or dairy-free (I’m what you’d consider dairy-light) but I love to create recipe options for those of you who are. Because as a gluten-free gal I know a thing or two about food restrictions and how exciting it can be to enjoy a classic recipe. Even if it is slightly modified.

If you’ve been following this blog for a while you’re familiar with my affinity for cashews and their amazing ability to morph into creamy, dreamy, dairy-like recipes. My homemade Cashew Milk, Vegan Caramel Cheesecake, Cashew Date Shake and Macadamia Cashew Butter are just a few examples.

Well, let me introduce you a new creamy, dreamy, cheesy recipe (though it has no cheese) – my Vegan Alfredo Sauce.

Vegan Alfredo Sauce Recipe Video

This sauce is extremely easy to make in a high-powered blender. Watch how I make it in the quick video below!

How to Make This Vegan Alfredo Sauce

Cashews that have been soaked overnight form the base of this alfredo sauce. Just toss those in a high powered blender along with garlic, lemon juice, onion, nutritional yeast and some herbs.

Blend everything together on high until creamy and voila – a super simple and amazingly delicious vegan alfredo sauce. I should mention that this sauce does thicken up as it’s stored in the fridge and sometimes while you’re cooking with it. If that happens and you want a thinner sauce, just add more water.

Nutritional Yeast is the Secret Ingredient

The ingredient that gives this alfredo sauce that wonderfully cheesy flavor (without any cheese) is nutritional yeast.

If you’ve never cooked with nutritional yeast before, it’s small little flakes (about the size of large sea salt flakes) of deactivated yeast which provides a nutty, cheese-like flavor. Nutritional yeast is also a significant source of B Vitamins.

How to Use This Sauce

So what do you do with this sauce? I’d start with topping it on every spiralized veggie imaginable. In fact, to get you started I’ve whipped up a Parsnip Noodle Chicken Alfredo and Whole30 Chicken Broccoli Casserole which both use this sauce. If you’re vegan, just replace the chicken with snap peas, mushrooms or another vegetable. You can also top this alfredo sauce on roasted vegetables or potatoes. So good.

  1. This is such an easy, yummy recipe! Question – how do you recommend heating it up? I just used it cold over a few days. i wasn’t sure if heating it would ruin the flavours somehow. Also, have you tried it with sauteed onions?

    • Hi Nicole- You can just simply re-heat in the microwave, it won’t ruin the flavors. As for suateed onions, I haven’t but that sounds so delicious! I’ll have to try that sometime.

  2. Holy Toledo! This recipe rocks! I ended up sauteeing mushrooms in butter, and adding leftover broccoli to warm, before tossing in cooked linguine and pouring in the SAUCE FROM THE GODS. So delicious. Thank you for sharing :)

  3. This is my third-try with a Vegan Alfredo sauce recipe. Third time is a charm! I like how easy and fast it is to make. Also how it doesn’t use oil.

  4. I used organic raw cashews truffle salt and smoked Pepper for it and put an extra clove of garlic in it it was so delicious I couldn’t stop spooning it out of the blender and just eating it!😀👍

    • Wow! I love the addition of truffle salt and smoked pepper! I’ll definitely need to try that next time :)

  5. Such a big fan of this Cashew Alfredo sauce! 
    It was amazing, like the real deal! My husband who is extremely picky couldn’t tell the difference. New staple in our house hold! Thank you! 

  6. This vegan Alfredo sauce is amazing!! I was skeptical that it was not going to be flavorful enough, but it is soooo good. I’ve made it two days in a row and I put it on my Trader Joe’s vegan protein burger today, so good!!

  7. This recipe is absolutely amazing!!
    One of my favorite ways to use cashew nuts.
    The video was very helpfull too for me when making this recipe for the first time!

  8. This was amazing! So easy! I soaked the cashews in boiling water for an hour instead instead overnight and it worked great! Just boil the water, take off heat and add cashews then wait an hour! 

    • Hi Caroline- Good to know the boiling method worked out for you! I’ll keep that in mind for anyone who doesn’t want to wait to soak it :)

    • This sauce was perfect and so easy to make.
      I also boiled water and used the cashews about 2hrs later. The sauce was smooth as silk:).
      We were looking for a sauce to make “chicken” spinach alfredo pizza. It was delicious 😋. Can’t wait to try it with spaghetti squash or zoodles!
      Thank-You for the wonderful recipe.

      • Hi Diana- I’m so glad you found this sauce delicious and used it for a pizza dish! You’re gonna love it over zoodles as well :)

  9. SO DELICIOUS! Even my family (who would never choose to eat vegan foods) loved this sauce. It’s so easy to make. I make a double batch and pour it on everything: roasted veggies, chicken, fried tofu bites, potatoes (sweet and baby rainbow), pasta, rice–even on salad as as salad dressing.

    • Hi Beth- I’m so glad you and your family loved this sauce! It took quite a bit of testing, but I tried to make it taste as similar as possible to the real thing. And I love how you’re using it over so many dishes :)
