Ingredient Spotlight and Substitutions

You’ll be shocked to find that this creamy pasta sauce is only a handful of basic ingredients – ones you possibly have on hand right now! 

ingredients needed to make vegan alfredo sauce - labeled with text

Cauliflower – Cauliflower florets are the base of this alfredo sauce. Once you cook them down to the point that they’re almost falling apart and super tender, they will blend uber smooth to make the best creamiest sauce ever.

Unsweetened Almond Milk – For this sauce, I use a unsweetened almond milk, but you can use any neutral non-dairy milk that you like as long as its unsweetened. Soy or rice milks would be good substitutions.

Dairy-Free Butter – In this recipe, I used Earth Balance dairy free butter, but I’ve also had success with Miyokos brand. Really any dairy-free butter will be perfect here.

Step-by-Step Instructions for Vegan Alfredo Sauce

Full ingredient amounts and in-depth details are at the bottom of the post in a printable recipe card.

  1. In a large pan, at medium heat, saute minced garlic with vegan butter for 30-60 seconds until fragrant.
  2. Add garlic butter to a high-speed blender and set aside.

3. To the same pan, add the vegetable broth and cauliflower florets. Bring to a boil. Cover and cook for 7-10 minutes until cauliflower is very tender.

4. Using a slotted spoon, remove cauliflower and add it to the blender along with the garlic butter. Also remove 1 cup of the vegetable broth from the pan and add to the blender.

5. Additionally, add salt, pepper, and almond milk to the blender.

6. Blend on high speed until mixture is smooth and to your liking. Add more broth as needed. Taste and adjust salt and pepper to your liking.

7. Pour over cooked fettuccine or other pasta of your choice. Top with vegan Parmesan and fresh ground pepper.

Insider Pro Tips

Add veggies

This pasta sauce is perfect on its own, but I love amping it up with more veggies and nutrients.

I like to add a steamer basket into the pan after I’ve removed the cauliflower and there’s just broth left. Then just add broccoli florets, mushrooms, asparagus, or whatever you may have on hand. Steam for a few minutes until fork tender, discard the broth, and add veggies into the pasta and sauce. Super simple!

Vegan Alfredo Sauce FAQs

Can I make this Vegan Sauce taste cheesier?

Yes absolutely you can! I often add my vegan parmesan cheese to basically any and every pasta dish I make. It’s so easy to make and just keep in a jar in your fridge.

How long will vegan alfredo keep in the fridge for leftovers?

I’d say about 5 days. That is, if you even have it around that long! My family gobbles it up in just a couple of days, but I do love that it makes enough for us to have plenty of leftovers for my small family of 3.

Can vegetarians eat Alfredo sauce?

Great question. Vegetarians choose not to eat meat products where vegans choose not to eat any animal products like eggs, milk, and cheese. Being that a traditional alfredo sauce is made with heavy cream and Parmesan cheese, it would be a suitable dish for a vegetarian diet, but not for someone following a vegan diet. But my Vegan Alfredo Sauce Recipe sure does rival just about any traditional alfredo sauce, so I’m sure you could serve it to vegans and non-vegans alike and everyone would be happy.

What would you serve with this vegan alfredo recipe?

I’d probably serve a salad or veggie side with this pasta to keep it a bit lighter. I personally love my Spiced Chickpea Salad, Cold Green Bean Salad or Boiled Broccoli.

And probably for dessert, this would be perfect with something like my vegan chocolate fondue (which can totally be made right in the slow cooker) for an extra special treat. Or maybe my Rainbow Fruit Nachos.

  1. Hey, Holly
    One of my favorite recipes of all time! I love the flavor of the sauce. Definitely a healthy substitute to the ones with all the additives. Although I am now vegetarian, this is still one of my go-to meals
