Dinnertime just got easier. This vegan fettuccine alfredo is a winner with everyone from kids to meat lovers: it’s just that good! The impossibly creamy sauce is a healthy spin on the traditionally rich pasta. It’s made with nutrient-dense cauliflower and protein-packed cashews instead of dairy. Make it with any type of noodle you choose (legume noodles, zoodles, etc) and it’s an easy 30-minute plant based dinner. Ready for all the secrets?

What people are saying

Alex and I sent this recipe to some friends and family who are close enough to us that they tell us their true opinion! Here’s what they had to say about this vegan fettucine alfredo:

  • “YUM! I love it! It’s super easy to make. I made it again 2 days later!” -Lisa
  • “This is the best vegan alfredo sauce! It’s my new go-to. It had just the right amount of creaminess and the seasoning was on point! Some recipes say the sauce is creamy and it comes out a little runny. This one is actually creamy!” -Maeghan

What’s in vegan fettuccine alfredo?

Who would have known that blending up a few veggies and nuts could create a creamy sauce that tastes like dairy? These days, there are so many inventive vegan recipe concepts for making creamy sauces. With this one, Alex and I wanted to use cauliflower to make a white sauce like our Cauliflower Sauce, but remove the Parmesan cheese. Here’s what we ended up with for this recipe:

Cook the ingredients for about 10 minutes on the stove. Then blend them until a creamy sauce forms and mix that with the noodles. Voila! You’ve got vegan fettuccine alfredo, an easy plant based dinner recipe in 30 minutes!

Is pasta healthy?

Good question. A new study found pasta can actually help you lose weight. The Italian researchers found that eaten in moderation, pasta can be part of a healthy diet. This is a full 180 of conventional wisdom, right? Alex and I have been enjoying pasta in moderation for years—so we’re glad it’s back in good graces.

Other noodle ideas!

There are lots of other options for pasta in this vegan fettuccine alfredo, especially if you eat a gluten free diet. Here are some options you could try:

  • Legume Based Pasta: Pasta made from lentils is becoming much more widespread these days. It can be made from black beans, lentils, or chickpeas. Alex and I have tried a few brands and found the texture is a little tough for us: but other people rave about it! We’re open to your suggestions in the comments below.
  • Zucchini Noodles: Making this pasta with vegetable noodles like Zucchini Noodles would also be tasty! You can make your own or they’re easy to find prepackaged.

How to cook pasta to al dente

If you’re using standard pasta for this vegan fettuccine alfredo, you absolutely must cook it to al dente. What’s al dente? In Italian it means “to the bite.” It refers to pasta that is still firm on the inside when cooked. The ideal al dente texture is a tender exterior balanced by a firm bite with a fleck of white at its core. Here’s how to cook pasta to al dente:

  • Boil the pasta in a large pot of salted boiling water.
  • While cooking, check pasta continually for doneness.
  • As soon as the pasta has a tender exterior but a fleck of white at its core, drain it! Even a few seconds can be the difference between al dente and limp noodles.

What to do with leftover alfredo sauce?

The sauce for this vegan fettuccine alfredo makes 6 cups total. Alex and I measured, and for our taste we liked using about 5 cups of alfredo sauce for 1 pound of pasta. That means, you’ll have about 1 cup leftover after making 1 pound of pasta.

What to do with the leftover sauce? Refrigerate it (obviously). Of course, you can use it on pasta again. But here are a few more creative ideas of how to use it up:

This vegan fettuccine alfredo recipe is…

Vegetarian, vegan, plant-based, and dairy-free. For gluten-free, use gluten-free, legume or zucchini noodles.

Description

WOW! This vegan fettuccine alfredo tastes decadent, but the creamy sauce is filled with healthy plant based ingredients. An easy dinner in under 30 minutes!


Ingredients

Scale
  • 1 pound fettuccine noodles (use gluten-free, legume, or zucchini noodles if desired)
  • 4 garlic cloves
  • 1 small head cauliflower (1 1/2 to 2 pounds), enough for 6 cups florets
  • 4 tablespoons olive oil
  • 1 cup raw unsalted cashews
  • 2 cups vegetable broth
  • ⅛ teaspoon onion powder
  • 1/8 + ¼ teaspoon ground black pepper
  • Pinch nutmeg
  • 1 teaspoon kosher salt
  • Finely chopped parsley, to serve

Instructions

  1. Mince the garlicChop the cauliflower.
  2. Make the pasta: Bring a large pot of salted water to a boil. Boil the pasta until it is al dente (start tasting a few minutes before the package recommends: you want it to be tender but still a little firm on the inside). Then drain the pasta and return it to the pot.
  3. Meanwhile, start the sauce: Heat the olive oil in a large Dutch oven, pot, or saucepan (that has a cover) over medium heat. Add the cauliflower and cashews and saute for 4 minutes until lightly browned. Add the garlic and cook for 1 to 2 minutes until fragrant. Add the vegetable broth, onion powder, black pepper, nutmeg and ½ teaspoon kosher salt. Bring to a simmer, then cover and cook 6 to 7 minutes on medium high heat until the cauliflower is tender when pierced with a fork.
  4. Blend the sauce: Carefully transfer the contents to a blender and add the remaining ½ teaspoon kosher salt and ¼ teaspoon more black pepper. Blend on high until a smooth sauce forms.
  5. Serve: Pour about 5 cups into 1 pound pasta (1 cup will be left over), or use it to taste. Top with finely chopped parsley and serve immediately.

    I bought your fun cookbook and have a question on this recipe. What is the sodium count, including the broth.
    I’ve already made it and it was delish!!!!

    1. Alex Overhiser says:

      Hi! We omit the sodium from our card because many ingredients we use such as beans, soy sauce or broth can have vastly different amounts and we don’t want to give false information. Even different brands of kosher salt can vary. A teaspoon of Morton kosher salt has 1920 mg of sodium.

  2. Kara Eva says:

    I never leave comments on blog posts, but this vegan Alfredo hit different.

    I’m an awful cool and this recipe was SO EASY. Like suspiciously easy.

    Added a few tweaks here and there — some of my fav seasoning, a little more or less broth to get the consistency just right, and it was AMAZING.

    Nobody ever likes my cooking lol but for the first time in a while the whole family sat down to grab a serving and enjoy it with me

    (Pairs great with a red wine too)

    Can you make your recipes shareable to Facebook?

    1. Alex Overhiser says:

      We can add that in the future.

  4. Roxanne Boyd says:

    The taste took some getting used to but I’m glad I made it. It is really good. The recipe says it has 8 servings but from what I saw, it does not say how much one serving is.

  5. Kathy Schleyer says:

    This recipe was very tasty!! My daughter has recently turned vegetarian so we tried this out and it was yummy and exceptionally easy.






  6. Renée Plummer says:

    This recipe was beyond great! I truly was not expecting the sauce to be this tasty & cheesy like. Its a winner! Going into my rotation regularly. Made enough that we will be having leftovers tomorrow night.






  7. Helene Crepault says:

    Hi, the sauce is really good. Mine did not get that smooth looking creamy look, more granular. Maybe I did not bend long enough? How long can you keep the sauce once in the fridge? Thanks.






    1. Alex Overhiser says:

      Yes! Try blending it a bit more. It can last 2-3 days in the fridge, but definitely loses a bit of flavor.

  8. Alice says:

    Very good and pretty easy. Just made it and I’m pretty proud of myself






  9. Sullivan says:

    The BEST vegan fettuccine Alfredo recipe. I’ve been vegan 5 years and have tried dozens of vegan alfredos , all of them pretty good but normally too heavy. This one is so so good! My whole family loves it and I’m about to make it again for the 3rd time this week cause my 1 year old is obsessed. Thank you for coming up with this delicious recipe! We will be making it for years to come!!






    1. Sonja Overhiser says:

      Thank you so much for such a kind note! We’re thrilled to hear this and so happy your family loves it. Thank you for letting us know!
