Vegan Garlic Alfredo Pasta
This vegan garlic Alfredo pasta is a creamy, cheesy weeknight dinner made for pasta lovers! It’s absolutely decadent, but made with a cashew sauce instead of heavy cream.

You’re going to absolutely love this vegan garlic Alfredo pasta. I’m talking cheesy, creamy, absolutely indulgent—it tastes like it came from a good Italian restaurant. Adding soaked cashews to this sauce makes it rich but not heavy, and gives it that traditional Alfredo sauce colour. Add a generous shake of Vegan Parmesan Cheese, a sprinkle of parsley if you’d like, and remember to pace yourself because you are going to want to DIVE into this pasta. (I feel similarly about this Miso Butter Pasta!)
Why This Vegan Garlic Alfredo Pasta Belongs on Your Menu
This is a recipe that straddles the line between comfort food and fancy date night meal. Here’s why you should make it ASAP!
- Super creamy and rich. And that’s EXACTLY what you went with an Alfredo sauce! Dairy-free doesn’t mean sacrificing taste or texture. This indulgent cashew cream sauce will leave you feeling satisfied, but it won’t leave you feeling heavy and weighed down.
- Easy to make. Pasta dishes are always some of the easiest dinners and this one’s no exception! Although you do have to roast the garlic and soak the cashews, both of those are pretty hands-off and can be done ahead of time.
- Versatile serving options. Add a vegan protein! Stir in some veggies! There’s a lot you can do to make this vegan garlic Alfredo pasta your own.

Notes on Ingredients
Here are the simple ingredients you’ll need for this vegan pasta dinner. Scroll down to the recipe card to find the ingredient quantities and recipe instructions.
- Pasta – Fettuccine is the classic, but you can use any shape you like.
- Parsley
For the Vegan Alfredo Sauce:
- Vegan butter or olive oil – I love Vegan Butter for added richness.
- Red onion
- Cashews – Be sure to buy raw cashews, not roasted. Soak overnight or in hot water for one hour.
- Pasta water – Helps bind and thicken the sauce.
- Unsweetened almond milk – Or another unflavoured, unsweetened plant milk.
- Roasted garlic – Roasted garlic deepens the flavour of the entire sauce and really brings it to another level. (You can also make Air Fryer Roasted Garlic.)
- Nutritional yeast – Provides a cheesy, umami flavor to the sauce.
- Sea salt
- Vegan Parmesan cheese – Use homemade or store-bought.
- Lime juice – Or lemon juice.
How to Make Vegan Garlic Alfredo Pasta
You’ll find the full instructions in the printable recipe card below, but here’s a visual overview of the steps involved.


- Cook the pasta. Boil the pasta in salted water, following the package instructions. Reserve ¼ cup of pasta water before draining.
- Cook the onion. Heat the vegan butter or olive oil in a pan over medium-high heat. Sauté the onion for about 5 minutes, until it’s softened.



- Make the sauce. Add the onion to a blender, along with the rest of the sauce ingredients. Blend until smooth and creamy, then season to taste.
- Assemble and serve. Drain the pasta and place it back in the pan or in a large bowl. Stir in the Alfredo sauce. Serve with parsley and vegan Parmesan for garnish.
Tips for Success
- Salt the pasta water. It may seem like a small thing, but salting your pasta water can really make a difference in the overall flavour of the dish. It helps to season the pasta from the inside out, as it will absorb the salt as it cooks.
- Get a head start. You can roast the garlic up to 3 days in advance or even make the sauce a day or two ahead of time. Just note that if you make the sauce ahead, you’ll have to warm it before adding it to the pasta.
- Don’t forget to soak the cashews. It’s so important for a vegan Alfredo sauce that’s creamy, not gritty!

Variations
- Add a veggie. Steamed broccoli or Garlic Mushrooms would be great additions to this dish, but so many veggies would work well!
- Give it a protein boost. Add slices of Vegan Chicken.
- Use different herbs. Instead of parsley, try using other herbs like thyme, rosemary, chives, or basil.
Serving Suggestions
I always recommend pairing pasta with my homemade Roasted Garlic Bread. I make it at least once a week! But if you want to keep things lighter, go with a salad. This Vegan Caesar Salad pairs well with Italian dishes.

How to Store and Reheat Leftovers
- Refrigerator: Store any leftover vegan garlic Alfredo pasta in an airtight container in the refrigerator for 3 to 4 days. I don’t recommend freezing this recipe, as the pasta will get mushy and the sauce will not be as smooth or creamy.
- Reheating: Microwave the pasta or warm it in a skillet set over medium-high heat, with a splash of broth or almond milk to loosen the sauce.

Thank you soo much Lauren!! ❤️❤️❤️
This is the 1st recipe I’ve tried using cashews as a sauce and I absolutely loved it! I’ve been transitioning to all plant based meals for a couple of months but was tentative to try something like this. Your recipe with roasted garlic caught my eye. It is so delicious my 14yr old even loved it. Will serve it 2 ways this week: zoodles & a black bean sesame fettucine pasta. Yum!!
Thank you so much Stacey for your comment! I’m so happy to hear that!!
Such a tasty dinner! Love that I already had all the ingredients in my pantry and fridge so I just whipped it up and served with a side salad. I like the addition of the garlic and onions. I used a white onion it was great. Yum!!
Thank you so much Mel!! I’m so happy to hear you enjoyed it so much and thanks for your comment!!
Absolutely delicious! It’s a new favorite of mine and will be added to my menu as a staple. Delicious and easy to make.
I’ve made a lot of Alfredo sauces in my day and I do declare this is #1! The addition of the onions and the roasted garlic is the secret, me thinks. Brava, Jessica!
We’re so happy that you enjoyed this recipe Laura! Thank you so much for reading and leaving such a nice comment!
When looking at recipes for cashew Alfredo sauces I chose yours because I thought the roasted garlic was a brilliant idea. And boy was it! This dish does not disappoint. Excellent job in the creation of this recipe and thank you for sharing it.
A few months ago I made a lifestyle change to go vegan, and when doing so it’s vital to have delicious foods/recipes so one does not feel flavor/food deprived and this is one of those recipes. I actually prefer it over normal Alfredo. This one’s a keeper without doubt.
Lastly my favorite pairing thus far is to top it with asparagus and roasted pine nuts. Simply delightful. Thank you again. 🙂
Hi Amandalyn,
Aww thank you so much for this sweet comment!! I am so so happy that you enjoyed this dish so much!! Wishing you all the best on your new lifestyle change!! LOVE the idea of pairing this with asparagus and pine nuts!! You’re so incredibly welcome!!
Okay, this recipe is ridiculously good. I’ve been hunting for a good vegan Alfredo for awhile now and my search is finally over!! So much flavor, and so creamy and delicious.I added some mushrooms and peas to the recipe but that was the only adjustment I made. And it was even better for lunch the day after I made this for dinner 😊
I had already tried to make some vegetarian sauces, but I had never liked the consistency until I tasted this one. It looks just like any other made with cream, so much so that my husband didn’t believe it was made with cashew nuts. Very tasty indeed!
“I’ve always been a fan of meat, but my mother is a vegan.
Your recipe really helped me a lot, easy to understand and so inspired, thanks alot.
Wow so happy to read that! Thank you so much for such a sweet review!
