VEGAN GARLIC ALFREDO SAUCE
One of most people’s indulgent comfort foods is alfredo sauce. I admit, I used to love it too, but I didn’t love how after just a few bites, I felt sick. There is such a thing as foods being too rich. Feeling nauseated and in a nasty food coma for hours after eating something isn’t really worth it to me. Enter the best Vegan Garlic Alfredo Sauce you’ll ever have.
HOW DO YOU MAKE VEGAN ALFREDO SAUCE?
Easy, you just need 6 simple ingredients:
- raw cashews
- onion
- garlic
- lemon juice
- nutritional yeast
- low sodium vegetable broth
First, you will cook your onions low and slow until really tender.
Add the garlic and cook until soft. Add the onion and garlic to a blender with the remaining ingredients. Blend until completely smooth.
Serve over pasta and enjoy the decadent, but healthy, vegan alfredo sauce!
No need to try any further anymore. This one is dairy-free and oil-free. Most vegan versions contain vegan butter or oil, not healthy. This one is made from cashews which make it exceptionally creamy. I wanted a whole food version and oil-free.
WHY VEGAN ALFREDO IS BETTER THAN TRADITIONAL
Traditional garlic alfredo sauce has butter, milk, cream, parmesan cheese (or other cheeses) and garlic in it. Major dairy overload! Bloated, icky feeling. It also does not have onion in it. However, I wanted to give my alfredo sauce that slightly, sweet richness typically reached by cream and butter, so I added cooked onions, lots of them.
Here’s a little side by side nutrition for my alfredo sauce in comparison to Olive Garden’s version:
Mine per 1/2 cup serving which is a hefty serving:
125.2 calories, 7 g fat, 5.6 g protein, 11.3 carbs
and Olive Garden’s: (they use heavy cream, milk, lots of cheese and 6 egg yolks, see here)
460 calories, 43 g fat!!, 9 carbs, 8 grams protein
Wow, what a difference! Hey, so it has a hair less carbs, but who cares when all of my ingredients are quality ingredients and not heavy on the heart. Nothing wrong with indulging occasionally, but you could eat my alfredo sauce weekly with much less guilt.
DOES IT REALLY TASTE LIKE ALFREDO?
I know what you are thinking….does it really taste like garlic alfredo sauce?? Well, my hubby said, “spot on” and then “it really tastes exactly like garlic alfredo sauce”. I was shocked. I’ll let you be the judge. I’d say it is pretty darn close, especially considering it doesn’t have any of the typical ingredients!
Regardless, it is delicious and very creamy and you can eat this alfredo sauce without tons of guilt.

the Best Vegan Garlic Alfredo Sauce
Ingredients
- 1 medium white onion, diced (200g) (MAKE SURE to measure out 1 1/2 cups b/c this is where lots of flavor comes)
- 1-2 cups (240-480g) low sodium vegetable broth, divided
- 1/2 teaspoon salt
- 1/4-1/2 teaspoon ground black pepper
- 4 x-large (15g) minced garlic cloves
- 1/2 heaping cup (75g) raw unsalted cashews (see NOTE)
- 1/2-1 tablespoon lemon juice (start with just 1/2 and taste after blended!)
- 2-4 tablespoons nutritional yeast (I highly recommend this Sari brand, it is non-fortified with much better taste.)
NOTE
- It is not recommended to sub or eliminate any of these ingredients, as I cannot vouch for the results if any are changed. The lemon juice is crucial, as it eliminates any cashew flavor.
NOTE
- If you are using raw cashews and you don't have a high-powered blender, then you must soak them overnight in a bowl of water, drain and rinse. Otherwise, your result will be gritty and NOT creamy. A food processor usually works better with soaked cashews versus a blender that isn't very powerful.
Instructions
- Add the onion and ONLY 1 cup of the broth to a large pan over medium to medium-high heat. Cook for about 8 minutes until the onion is very tender. (Add a tiny bit more broth if it is cooking too fast or turn the heat down, so the onions don't burn) After 8 minutes, add the garlic and cook a couple of minutes more, stirring often. All of the broth should have evaporated by now. If not, keep letting it cook until the broth is GONE. You don't want any more liquid once it's done cooking, so the end result is thick and creamy.
- Add the cooked veggies (the onion and garlic) to a blender. Start out by adding JUST 1/2 cup more of the remaining broth and add the remaining ingredients (salt, pepper, cashews, starting with JUST 1/2 tablespoon lemon juice, nutritional yeast-starting with just 2 tablespoons yeast). Blend on high for a couple of minutes until very creamy and smooth. Add any more broth to reach desired consistency, if necessary. I did not. If you don't add more broth, you would likely not need any more yeast. Taste and add any more salt & pepper or lemon, if desired.
- Serve over preferred pasta. Note: When preparing your pasta, make sure to salt your water well, so your pasta has flavor and isn't bland, which can affect the end flavor result of the dish. I add around a tablespoon to a large pot of boiling water. Garnish with parsley, lemon zest and salt & pepper, if desired. Add any veggies you like. I like to add broccoli or even peas. Store leftovers in the fridge. The sauce will thicken up even more overnight, which you can thin out a little with a touch of broth when reheating, if necessary.
AMAZING! Best Alfredo I have EVER had! This recipe is so easy and if you are looking for comfort food, this is the one!! I added 2 types of mushrooms as well. Highly recommend!!
Simple and delicious!! A classic made vegan! My non-vegan family members also loved it!
Thank you for this recipe, Brandi! I’m really looking forward to trying this, when I get all the ingredients together. I love alfredo sauce and even have all the makings, but I am trying to lose weight and cut back on animal fats, for health reasons (heart health and blood pressure, mainly). I really appreciate that this uses only 1/2 cup of cashews, because those can be expensive, in terms of cash and calories. Thanks, again!
Made this as I have cut out a lot of dairy from my diet and my goodness was it delicious!! Never expected it to taste that good! I topped it with some thinly sliced carmelized onions and it was perfect!
So happy to hear that Carolyn!!
Really great recipe! I needed more liquid than expected but overall stellar taste. I think I’ll cook the onions in oil next time because I loved a good sauteed onion. Easy, quick, and YUM.
This recipe is so fast and flavorful. I only wish I doubled the recipe more often! The onions really make this sauce- and I would never have considered adding them myself. I make this almost weekly and serve with fettuccini, broccoli and mushrooms. Delicious when its first made and the as leftovers (which never last more than a day at my house).
This recipe is simply amazing. Admittedly I was in a hurry and just sautéed the onion and garlic (didn’t really measure), dumped the ingredients all into my Nutribullet and it was AMAZING. EVERYONE in my family loved it. The kids too. We are trying to eat plant based as a whole, but the kids are still “transitioning”. I will make many more of your recipes. You are the best! Thank you so much!
Love it and recommend it all the time! DD and I were arguing over nutritional yeast amounts (I thought she wasn’t reading recipe correctly) as the version I have saved has 1/4C + 1 Tbsp and the version currently here shows 2-4 tablespoons. Why the change?
Yes, I changed it probably 1-2 years ago. I felt after making it again that it didn’t need that much nutritional yeast and changed it. People’s taste preference varies so much with nutritional yeast. Also, some brands taste very different from each other, so a variance is best!
Hi. This looks delicous. I am following the Plant Paraodox diet which disallows cashews, sunflower, chia and pumpkin seeds. Is there any other nut(s) that would work with this? I would love to try it. Thanks, Nicole
I would make this one instead. https://thevegan8.com/nut-free-vegan-garlic-alfredo-sauce/
Thank you SO much for this recipe! It is absolutely fantastic! Found it just a couple of weeks ago and have already made it 5 times. My picky af teenage daughter requests it. Thanks again!
I am in AWE!!!! I have tried too many different recipes for vegan alfredo sauce, and this one takes the cake. You have the proportions down a tee. AND! You have my heart as an incredible credible chef that knows her craft. Thank you so much for sharing. My search is finally over <3
Aww yay! So glad, thank you!
So easy to make!
And I have all these ingredients in my house
Absolutely incredible!
A nice little touch I add is some coriander to finish it and it gives off a Herby little finish
Yay, so happy you loved it!
Loooks so delicious! I must try this! Xoxoooxox
Hi there,
My name is Nani Jo and I live in New Zealand. I love your recipes…
In this recipe where it says (MAKE SURE to measure out 1 1/2 cups b/c this is where lots of flavor comes). What does b/c mean please??
regards
Nani Jo
Hi! That means because 😊
You said not to substitute any of the ingredients but I hate the taste of nutritional yeast. I was diagnosed with stage 2 breast cancer back in August and I have changed my diet and am going the natural route. Will I notice the flavor of the yeast in the sauce?
I love that you worked hard to come up with this recipe and then shared it. I would love to give it a go over zucchini noodles.
Hi Crystal, sorry to hear that. I wish you the best recovery! You can totally leave out the yeast. I actually rarely use it anymore since my hubby can’t have it. It does add more flavor, but the sauce is really good without it, you may just need another pinch of salt since nutritional yeast is salty.
Made this to non vegan family members and they couldn’t believe there was no cream in it. The taste was so good and nothing left. The next time I made it I doubled the recipe so that I could have some for work next day. Have given your web site to many people. Thanks
That is so wonderful to hear, thank you Jackie for the review!
Wow!!! So happy I found this recipe! I’ve been dairy-free and gluten-free for only 6 months now and was craving Alfredo! This is soooo good! And easy! Just Wow!
This was easy and delicious! I made it with spaghettini, roasted brussel sprouts and sauteed mushrooms with a bit of finely chopped parsley on top. So yummy!! Thanks 😊
So, I doubled the recipe, being careful to get all the measurements correct, and what came out was not smooth and creamy. Isn’t it the cashews that give this dish creaminess? If so, I’ll know to increase the amount of cashews.
Hi Dylan, if it’s not creamy, then it sounds like you added too much broth. Start out with much less broth next time and only add a bit at a time. Did you idea Vitamix to blend the cashews?
No, I added all the ingredients in the food processor after I blended the onion and garlic concoction. I’ve got about a cup of cashews soaking in hot water right now. I plan on blending them till they’re creamy, then slowly adding the previous mix to see how it turns out.
A food processor won’t get it as smooth so just blend it longer, that’ll help too!
Thanks Brandi. I kept trying that, even with a fresh cup of soaked nuts, then adding the other, but it just didn’t turn out creamy and smooth like the pic above.
I followed your recipe exactly and weighed the grams to get it right. It was delish. This is a keeper. I would like to know if you have ever used raw sunflower seeds in place of cashews? If so, do you use the same weight, and how is the flavor difference ?
So glad you enjoyed it Donna! No, I haven’t with this exact recipe, but have with others. Sunflower seeds are much more bitter and less creamy, so it will not taste the same or be the same creamy texture. It will work technically, but just be prepared of the flavor change a bit. You’d use the same weight, although sunflower seeds do make the sauce thicker, so you may need to add a touch more broth/seasonings.
Wow! This is delicious!! Thank you!
You’re so welcome, glad you loved it!
I made this for my daughter while she was staying with me recovering from back surgery. She has many issues with dairy and had stated that she missed alfredo sauce the most. She LOVED it. She does not have a food processor or blender and wanted me to make a big batch for her to take home. Have you ever canned or froze the sauce?
That is great! Yes, you can freeze it! Thaw and reblend if needed to make smooth again.
I just tried this and it’s so tasty!! I put it over spaghetti squash and had roasted carrots and baby potatoes on the side. Sooo so yummy thank you for the recipe!
This is the first truly vegan recipe I’ve tried. I am not vegan but really want to have a more plant-based diet. This recipe is amazing! My hubby and I loved it. I mixed in some broccoli for variation. It’s definitely a keeper. Added just a dash of nutmeg, too. I can see myself making this often and using it for lots of different things. Great job!
okay SO i didn’t have the lemon which i know was stated as super important, BUT, even without it, this recipe is AMAZING. i think next time i’ll make it a little bit thinner by adding more broth, as suggested, just for like texture reasons, but the flavor is incredible. i added steamed broccoli and my toddler ate it all up. seriously delicious and highly recommend.
Awesome! Yes, that’s exactly why I add a range of broth so you can start with 1/2 cup and add as desired to reach what you like best!
Just made this sauce and its fantastic. I also love how it doesn’t need too many cashews, keeping it cheap! Thanks (:
I didn’t use any broth cuz I didn’t have any, but it was absolutely delicious regardless. I could barely stop myself from eating. I also used my ninja blender for sauce for the first time and it was so incredibly smooth and creamy. I love it!!
This really is the best! I use this recipe so often, and in all different ways. Thank you for it!
