Vegan Alfredo Sauce Recipe Ingredients

You only need 10 ingredients to make this vegan Alfredo sauce:

  • Cauliflower – It creates the sauce’s luscious creamy texture.
  • Cashews – Along with cauliflower, they make the sauce thick and creamy without any dairy. Make sure you use unsalted raw cashews in this recipe. Roasted cashews will give it a cashew-y taste.
  • Garlic – For sharp, savory depth of flavor.
  • Nutritional yeast – With its cheesy flavor, it replaces the Parmesan that you’d find in regular Alfredo sauce.
  • Lemon juice – For brightness.
  • Dijon mustard – It gives the sauce a savory, tangy kick.
  • Extra-virgin olive oil – It makes the sauce rich and smooth.
  • And salt and pepper – To make all the flavors pop!

How to Make Vegan Alfredo Sauce

This vegan Alfredo sauce recipe is super easy to make! Here’s how it goes:

First, cook the cauliflower and the cashews. Yep, you read that right! I like to boil the cashews with the cauliflower so that they’re easy to blend. It has the same effect that soaking the cashews would, but it’s way quicker.

Bring a large pot of salted water to a boil, add the cauliflower and cashews, and boil for about 8 minutes. When the cauliflower is tender, drain the cashews and cauliflower and place them in a high-speed blender.

Next, blend! Add the olive oil, garlic, lemon juice, nutritional yeast, Dijon mustard, salt, and pepper to the blender. Pour in 1/2 cup water, and blend until the sauce is smooth and creamy.


Vegan Fettuccine Alfredo


Finally, serve! Cook a pound of fettuccine (or any pasta you like) in a large pot of salted boiling water. When the pasta is al dente, drain it, reserving 1 cup of the starchy pasta water.

Transfer the pasta back to the pot, pour in the sauce, and stir to coat. Add the pasta water, as needed, to thin the sauce to a smooth, silky consistency. Season to taste, and enjoy!

Vegan Fettuccine Alfredo Serving Suggestions

I love to serve this vegan fettuccine Alfredo with focaccia or crusty bread. That way, I can mop up any sauce that’s left at the bottom of my bowl! Then, I round out the meal with a salad or vegetable side dish.

To make a simple green salad, toss mixed greens with lemon vinaigrette, Italian dressing, or Greek salad dressing. Otherwise, serve this vegan fettuccine Alfredo with one these salad recipes:

Not in a salad mood? Pair your pasta with sautéed mushrooms, roasted broccoli, or Brussels sprouts instead!
