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
- 1/2-3/4 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 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.
Thanks for the yummy recipe. I will be adding this to our dinner rotation. ❤️
Amazing!! My boyfriend, who normally hates all pasta sauce (vegan or not), LOVES IT! Huge win for me because I love pasta sauce, so now I can make this every time.
I had cashew cream already made so I used it instead of raw cashews and additional broth. I also didn’t have any nutritional yeast on hand so I used miso paste and it was delicious!!
I’m somewhat offended the overall rating is 4.99 and not a perfect 5. This receipt is INCREDIBLE. Simple but every ingredient and amount is just perfect. This sauce is just as creamy and has as much flavor as any alfredo sauce I’ve ever had. Brillant. Thank you for sharing it!
Hahaha, that made me laugh!! Thank you so much! I’m so happy you love the recipe so much! Thank you Lewis!
Soo good!! I didn’t think it could be true but all the comments made me give it a try. I put it over zucchini noodles! Fantastic!
Aww yay, really glad to hear it Ciera!
How many does this serve?☺️
Hi Klaudia, this makes about 2 cups of sauce, so 3-4 people!
I’M ADDICTED!! I make this just as often as I can, and I make a double batch every time. I recommend it to anyone who will listen! It’s so velvety smooth and just delicious. I’m not even vegan and I will take this version over any dairy alfredo ANY day.
SO awesome to hear, thank you Madi! Glad you love it more than the dairy version, whoop!
I’ve made Salmon Alfredo Past twice in the past week using this recipe and it is PERFECT. I added mushrooms to the pot when I was cooking the veggies and it added to the flavour. Thank you so much for this recipe and I truly love the simplicity of the ingredients.
I’ll try your recipe asap! Can I freeze it? Thank you! ☺️
Yes, freezing is fine, you will need to thaw it and reblend to a smooth consistency.
Absolutely delicious! Super easy to make and very nutritious!
So I made this, this morning for my meal prep for the week. I’m a flight attendant and meal prepping is how I survive being vegan with little options when I travel for work. This was sooooo delicious. Thank you Brandi girl for this recipe. I really love it and appreciate it !
Cuisine American? I don’t think so! Although I suppose this version is…
Well, based on a good Italian one. Still, going to try this tonight.
I forgot to give a rating in my comment earlier. It’s a 5 star recipe!
So happy to hear that, thank you Sharon!
Thank you for this excellent recipe. I recently started eating a vegan, no added oil diet after years (16) of being a vegetarian. For health reasons mostly. The fat is a bit higher than I would normally eat in a single meal but oh boy, was it ever worth it! I liked it so much, I have made it for supper again tonight lol 😊
I’m not sure how you do it!!! We’ve tried the cauliflower version from another vegan blogger… good, but lacking something. I’m pretty sure my butter loving parm loving husband will be fine without both when he tries this!!! The heavy cream, butter, parm, salt, and garlic recipe I use for his birthday dinner every year (seriously, I only cook it once a year) tastes more like a buttery-creamy-dairy cheesy version, but this is FANTASTIC, and WORTH THE TRADE!!!! We have gone 100% WFPB since having some health scares and your recipes make it SO easy!!! <3
Aww yay Kelley! So happy to hear this!
This. Was. Amazing. 100% will be making this again! Thank youuuuu!
Brandi Hi
I am thanking you in advance just reading all the comments lol! Problem can we use cashews in the bag?I can’t find raw cashews anywhere… or are those considered raw. I only see them unsalted at wal-mart and places in the bags? also I have a kitchen aid mixer and a older model Cuisinart is either ok to blend these babies! I’m so ready to make this after spending $8 bucks on a jar at whole foods.
Check the ingredients to make sure they don’t say roasted and no added oil/salt and if they don’t, they should be raw. Roasted usually say roasted on the bag or can. I would use the food processor but make sure to soak the cashews in a bowl of water overnight, drain and rinse. It’s all listed under NOTE.
Floored!!! This is incredibly creamy and delicious and by far the best out of all the vegan alfredos I’ve ever tried. I made it with soaked cashews.
So awesome to hear that Julia!
This Alfredo sauce is amazing – it’s so similar to a heavy cream and cheese sauce! Thank you for a great recipe!
Thank you Brandi, you are the best!
The best and easiest recipe!! Ididnt change a thing!!!
This was so delicious! I followed the recipe exactly and then added sauteed veggies to make a primavera alfredo pasta. The family LOVED it. Thank you!!
Oh my goodness.. this sauce! No one was able to tell it was vegan. Seriously wow’d by this recipe. I subbed apple cider vinegar because I didn’t have lemons, added a couple tablespoons of trader joe’s kale pesto and added sauteed onions, red peppers, zucchini and kale. A hit with the hubby and kids!
My sauce was sooo creamy and delicious and garlicky but a touch too sweet. I’m suspecting it was my vegetable broth of choice. Which brand do you use, Brandi? Everything else I did exactly the same 🙂 thank you!!
Hi Rebecca! I’ve never had that happen before or heard that! Did you use white or yellow onion? I’ve used several different broths and all have been fine. I’ve used pacific low sodium brand and Trader Joe’s brand and other ones. Just make sure there isn’t any added sugar. Also, different onions are sweeter than others, so white onion is best here.
Thank you for your wonderful recipes. I’m sorry people are not giving you credit. Hopefully most of us are.
Yes, most are, which I’m very grateful for, thank you so much Randy!
WOW !! XOXO This was fantastic. Quick and easy. Hit the spot. I used the recommended nutritional yeast, a very fine texture. I also used a large sweet onion and the garlic with the center stems removed. Garnished with peas. YUM
So awesome to hear Chris!! Thank you!
So awesome to hear, thank you Chris!
This was delicious! Can you freeze this sauce?
Yes! Just thaw overnight in the fridge and reblend to make it smooth again and heat on very low heat.
