Recipe | (Vegan!) Sun-Dried Tomato Fettuccine Alfredo + How To Make Your Own Sun-Dried Tomatoes

Vegan Sun-Dried Tomato Fettuccine Recipe

Vegan Sun-Dried Tomato Fettuccine Alfredo
I’ve only had real fettuccine alfredo once. I went through a phase about 10 years ago where I used to eat fettuccine alfredo Lean Cuisines a few times a week. (Don’t judge me!) And then I thought, “Hey, this stuff is pretty good! Fettuccine alfredo is my thing now!” So when Chris and I went on vacation to Michigan (which, by the way, is what people from Chicago do–they go on vacation to Michigan) and got dinner at an Italian restaurant, I thought I’d order their fettuccine alfredo. The waiter brought it out and I swear there had to be two pounds of pasta in that bowl. Two pounds of pasta bathed in super rich alfredo sauce. And cheese! Lots of cheese. I don’t think I’ve ever felt so sick after eating a meal in my life and I barely even put a dent in that pasta. Real fettuccine alfredo–never again!

Vegan Sun-Dried Tomato Alfredo Sauce
But I still love a good creamy pasta sauce. Just not so heavy. Cashew cream is perfect for this. It’s creamy and rich, but it doesn’t make you feel sick after eating it. If you’re skeptical about the whole cashews-as-dairy-sub thing, give it a try. I was a skeptic too, but it really works. This alfredo sauce is vegan and soy-free; I like to use a little homemade veggie broth in mine for a boost of flavor, but if you want to make a raw version of the sauce to serve over zucchini noodles, it’s easy to do by substituting the broth with filtered water and using dehydrated tomatoes instead of oven-dried ones.

How To Make Sun-Dried Tomatoes

No, I’m not going to tell you to leave your tomatoes out in the sun! Even the store-bought ones that say they’re sun-dried usually aren’t. If you’ve got more cherry or grape tomatoes than you know what to do with, you can use them to make your own dried tomatoes in the oven. They are the best sun-dried tomatoes you’ll ever taste–you can bake them until they’re still tender if you want softer tomatoes or leave them in the oven until they’re completely dried out. All you have to do to make them is:

1. Cut the tomatoes in half.
2. Put them on a baking sheet, cut side up, and drizzle or spray them with a little olive oil.
3. Sprinkle the tops of the tomatoes with salt and pepper.
4. Bake the tomatoes at 225ΒΊF for 2-4 hours, until they’re as dry as you want them to be.

Homemade Sun-Dried Tomatoes
Easy! You can either put the tomatoes in a jar, cover them with olive oil, and refrigerate them or you can pop them in a freezer bag and freeze them until you need them. I love adding them to pasta, pizzas, and salads.

Sun-Dried Tomato Fettuccine Alfredo

You'll never guess that this rich, creamy Sun-Dried Tomato Alfredo Sauce is dairy-free!
Prep Time: 30 minutes
Cook Time: 10 minutes
Total Time: 40 minutes
Servings: 4 servings


  • 1 cup raw cashews soaked in water for at least 30 minutes
  • 3/4 cup vegetable broth
  • 1/2 cup oven-dried tomatoes see recipe in post
  • 1 tablespoon nutritional yeast
  • 1 tablespoon fresh lemon juice
  • 1 clove garlic
  • 2 tablespoons thinly sliced basil leaves
  • Salt and pepper to taste
  • 8 ounces whole-wheat fettuccine cooked according to package instructions


  • Combine the cashews, broth, tomatoes, nutritional yeast, lemon juice, and garlic in a blender or food processor. Blend on high until the sauce is completely smooth. Stir in the basil and season with salt and pepper to taste.
  • Transfer the pasta to a large bowl and toss it with the alfredo sauce. If the sauce is too thick, add a tablespoon or two of cooking water from the pasta.


I'm sure store-bought sun-dried tomatoes would work in this too, but I haven't tried it myself. If the tomatoes you buy are especially dry, let them sit in warm water for a few minutes to plump them up.

    I made this! the taste is good but mine came out a stickier creamy consistency than what it appears in the recipe. I think next time I’ll add more stock to the blender? Would that make it a thinner creamer consistency?

      Did you thin out the sauce with the cooking water from the fettuccine? Usually that will do the trick; adding more stock to the blender will help too! Sometimes you kind of have to improvise with cashew sauces and add a little more liquid to get them to the right consistency. πŸ™‚

    Just made this today!!! Meatless Monday. It is very good, even though hub’s isn’t fond of Meatless Monday & Leftover Tuesday, never has he had a “Vegan” Monday. We really enjoyed it. I also added broccoli and cauliflower, with the sun (oven) dried, fresh tomatoes. I am however, not because of the recipe quality, but the cost of fresh cashews, thinking about using chick peas in place of the nuts. Any thoughts? We’ll just call it Hummus Fettuccini Alfredo!!! Thanks you for the wonderful recipe…even took some to work for the “doubting meat eaters”!

      I’ve never used chickpeas to make a vegan alfredo sauce, but I’m pretty sure I’ve seen a few recipes that used cannellini beans. Another possibility would be to use cauliflower: πŸ™‚

      Vegenaise makes a wonderful “alfredo-type” sauce with absolutely NO effort. But, I would suggest half & half because Vegenaise has a LOT of calories.

    Hello hello!!
    I’m OBSESSED with this recipe!! I have it with spaghetti, brown rice, veggies or as a quick yet amazing dip! I was just wondering the nutritional info. How many calories in a serving and what is the serving size? (Manly cause I tend to eat it all, even just with a spoon!)
    The best sauce! I recommend it to everyone!!

    I would like to make your oven-dried tomatoes, and the alfredo sounds great, too. Have you frozen any of the tomatoes? I have to wonder if they thaw out mushy?
    I have made cauliflower alfredo from and it was very tasty.
