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 absolute BEST Vegan Garlic Alfredo Sauce that tastes like the guilty version. Lots of onion is the secret to this easy, low ingredient and rich dairy-free and oil-free alfredo sauce. You will be shocked there is not an ounce of dairy in it!

Yields 2 cups 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.

      Do you mean hours or days advance? It’s best fresh but if you make it early, reheat on low. Reheating will make it thicken easily so don’t overcook it.

    I found your recipe last year in December. I made it for my youngest daughters birthday and her amd her husband said it was the best Alfredo sauce they had ever had I agreed so past the recipe on to my other daughters who were spending Christmas together and they also raved about it. One of them eats plant based where the others love their animal products. I made shrimp , scallops and salmon to accompany it and added veggies to the dish. I have to have my veggies.
    Thank you for this wonderful recipe. We will be celebrating our family Christmas this weekend and it will be our first family meal.

    So yummy. I’ve made it twice now in less than a week and added a nice sized dash of paprika on the second one and omg so satisfying. Add frozen veggies, frozen spinach and mushrooms with favourite pasta then BOOM a bowl of proper comfort food. Thank you for an easy yet impressive recipe, my meat eating husband even enjoyed.

      So happy it was a hit Stephanie! Yes, it yields about 2 cups sauce, depending on how much broth you used, but if based on 4 servings (1/2 cup sauce each) it would be 145 calories, 5g protein, 13.8 carbs, 8.9g fat, 395mg sodium, 2.2g fiber, 3.4g sugar. This of course is based only on the sauce, so you would have to add whatever pasta you used.

    I love this recipe and I have made it over and over again with perfect results. However I made it today, exactly according to recipe, the only difference being I made it at my daughter-in-laws,s and she has the Ninja blender. I soaked my cashews as alway although I apparently didn’t have to. It is gritty and not smooth as other times, I can’t figure why, the high powered blender should have made it better. I just curious why this happened.

    I have used this recipe so many times over the past couple of years- it is amazing. On pasta, veggies, vegan stuffed shells or ravioli, even spread on toast or sandwhiches… sometimes i dress it up a bit by adding some pine nuts, miyokos mozzarella, a dash of truffle oil or seasoning- i love it and just wanted to express a little gratitude now that i am back on this page for like the 20th or 30th time so i can have it over some almond ricotta tortellini and fresh spinach tonight 😋

    Wow! I was shocked at the flavor. This was so good. My husband and I just watched “Eating You Alive” and saw this recipe. I happened to have all the ingredients on hand (I will admit to using chicken broth instead of vegetable stock though because it’s what I had). I love Alfredo sauce but the dairy version does not often agree with me or my husband. This recipe is amazing, it’s super filling and I didn’t feel gross after eating dinner. While I made this, my son made your flat bread recipe. We are pleasantly surprised with the results from the 2 recipes we’ve tried so far. We’re planning on trying more of your recipes and I look forward to purchasing your cookbook when I get paid next.

    This afredo sauce was so good! And I didn’t really think I liked alfredo sauce all that much. Then I saw that this was your most popular recipe on the blog so I had to check it out. Your comment about how eating the tradition alfredo would leave you feeling not so well. I thought, hmm, maybe that’s why I remember not caring for it. So I read some (a lot!) of the reviews and was convinced I should try it. I made the recipe as written and it was easy and really delicious. And I felt good after eating it! 🙂 It will definitly become part of our meal rotation.
    Oh, and I had some leftover sauce and used it on a naan pizza crust and that was delicious also!
    Thank you, Brandi!

    On my nutrarian journey, I really miss pasta; this is my comfort food, especially Alfredo!

    26 days into a drastic change of lifestyle food journey left me wanting a little something indulgent. Enter vegan garlic Alfredo sauce!

    I made this with baked spaghetti squash with mushrooms, onions, and broccoli. I promise, it was a restaurant-worthy meal! Talk about indulgence! This vegetarian “pasta” entree will be joining my regular rotation now!

    I can hardly wait to try another recipe!

    Thank you for healthy and delicious, nutritious food options that fit into my current eating lifestyle.
