Vegan One Pot Fettuccine Alfredo

Hands-up if you LOVE one pot meals! When I was an exchange student in France, I only owned ONE POT. Can you believe that? It was a deep and wide pot-like-pan that I bought in the market. I did all of my cooking in my sole pot for six months. I can honestly say that during that time I learned a lot about cooking using local, fresh ingredients AND how to make a full dinner in one pot. Fast forward several (ahem!) years later and I still love a good One Pot meal.

What are your go-to after work meals? Even though I adore cooking, experimenting, and spending time in the kitchen, I am usually not so keen on dirtying up a whole bunch of dishes and spending hours on a meal when I come home from work. Can you relate?  I came up with this Vegan One Pot Fettuccine Alfredo recipe last week after work. I wanted to make a healthier alfredo without all the dishes or work.

This 30-minute, 9-ingredient (+ salt and pepper), One Pot Fettuccine Alfredo is healthy, dairy-free as well as SUPER garlicky and rich. Did I mention how easy it is to make?

Saute the shallot, garlic, and herbs. Add the creamy sauce, (optional) green peas, and pasta to the post. Cover and simmer for 9-11 minutes until the pasta is cooked and the sauce is absorbed into a velvety Alfredo sauce. Cooking the pasta in the same pot where you sauteed the herbs, onions, and garlic brings out SO much flavor in this meal.

↓↓↓↓ YUM.

I mean look at all that CREAMY PASTA.

I like to stir in fresh basil and chives at the end as well as top everything off with my Homemade Vegan Parmesan (I always have some on hand).

Vegan One Pot Fettuccine Alfredo

  • Author: Ceara
  • Total Time: 30 mins
  • Yield: 5 - 6 servings 1x


Rich, garlicky, and creamy Vegan One Pot Fettuccine Alfredo made with only 9-ingredients and ready in 30 minutes flat. I love making this for easy, weeknight meals!


  • 1 box fettuccine pasta
  • 1/2 cup raw cashews (or 1/4 cup raw cashews and 1/4 cup unsalted pumpkin seeds)
  • 56 shallots or 2 medium white onions, finely chopped
  • 5 cloves garlic, minced
  • 1 tbsp basil or herbes de provence
  • 2 cups frozen peas (optional)
  • 3 cups vegetable broth
  • 2 tbsp lemon juice
  • 1/4 cup nutritional yeast
  • Sea salt and pepper


  • 1/4 cup fresh basil, chopped
  • 1/4 cup fresh chives, chopped
  • Vegan Parmesan


  1. Soak cashews in hot water (or soak in cold water overnight in the fridge) while preparing the rest of the Alfredo sauce.
  2. In a large deep and wide pot, over medium heat, saute shallots and garlic with a splash of water until translucent. Add the basil (or herbes de provence) and frozen peas to the pot. Continue to saute, adding a splash of water when necessary.
  3. Rinse the cashews. Add the cashews, vegetable broth, and 3 cups of water, to a blender. Blend until creamy smooth.
  4. Add the sauce to the pot. Add the Fettuccine to the pot, making sure that all the pasta is covered with the sauce. Cook on medium heat, stirring every couple minutes so the pasta does not stick to the bottom of the pan.
  5. When the pasta is cooked to al dente and the sauce is mostly soaked up, stir in the lemon juice and nutritional yeast. Sprinke with sea salt and pepper to taste.
  6. Garnish with fresh chives, fresh basil, and vegan parmesan.


1) The sauce may dry up a bit if you do not serve it right away. Stir in a splash of vegetable broth to keep the pasta creamy.

  3. I made this today and it was good and everyone like it. Great recipe . I let it go just a touch to long and it was a bit dry. Next time I’ll get to it quicker. One more recipe to give people when they ask “What do vegans eat?”

  4. AWESOME!! This was a big hit with the Mister!! The only problem I had was being able to keep all that liquid from leaking out of the blender while blending it – had to hold the top on HARD. But you definitely need that much liquid cause the pasta really soaks it up. Super delicious & easy recipe. Thanks!!! Another winner!!

  5. Very clever idea using the cashews for creaminess and shallots just make everything taste better! I have missed Alfredo sauce so much since going dairy free…I might have to buy the bullet and buy some nutritional yeast.

  6. In your directions you state broth plus 3 cups of water, for a total of 6 cups of liquid. Is that correct? Mine came out very liquidy instead of creamy so I had to thicken it. Did I misunderstand?

    1. Same questions, about to make and do not want to have it all runny. Guess I’ll start with 3cups veg broth and go from there….

      1. Hi Susheila,

        The pasta cooking and the starch from the pasta absorbs the water, making the final result of this sauce creamy and rich! You may even need a splash more water at the end depending on the pasta you use.



    2. Hi Shawna,

      Did you use an entire box of pasta? How much pasta did you use? It should not come out liquidy at all! The pasta cooking and the starch from the pasta absorbs the water, making the final result of this sauce creamy and not runny at all.

      Let me know!

  7. Simply stunning! Silky smooth creamy garlicky mouthfuls of deliciousness. Try it with oven roast baby piccolo tomatoes and crispy fried onions scattered in top instead of th Parmesan
