Simple Ingredients for Vegan Pasta Sauce
I love how simple the ingredients are in this recipe. They’re fresh, easy to find, and pair extraordinarily well together.
- Tomatoes: this recipe calls for roasting, so we recommending using medium/large tomatoes, but any kind will work.
- Yellow Onion: onion offers up an incredible flavor add. It’s savory, yet sweet at the same time.
- Garlic: roasted garlic is a dream. This vegan pasta recipe calls for 6 cloves, but heck, you could use an entire head if you wanted! Check out this quick tutorial for how to roast garlic.
- Olive Oil: olive oil is used to help break down the tomatoes and onions during roasting.
- Pasta: feel free to use any kind of pasta your heart desires.
- Raw Cashews: raw cashews are the basis of this vegan pasta sauce. We’ll give you the full run down below of whether to use raw or roasted cashews.
- Fresh Basil: fresh basil adds such a wonderful freshness to this sauce. Don’t skip it!
Do I have to use raw cashews?
We used to be sticklers about using only raw cashews when you make a creamy vegan pasta sauce. However, since we’ve made this so many times (and so have you), we thought we’d test both options.
Both raw and roasted cashews will work. It does depend on your personal preference for flavor.
We found that roasted cashews tend to leave a little bit of a smokier or sweeter flavor, but overall the texture of the vegan pasta sauce does not change. It comes out creamy and thick no matter what type of cashew you use.
Can I use a different kind of nut?
We haven’t tested this recipe with any other nut other than cashews and we don’t recommend swapping it.
Why didn’t you use nutritional yeast?
You’re more than welcome to use nutritional yeast, but we wanted to make a vegan pasta sauce without it that still tasted good and was a creamy as ever!
Is this vegan pasta gluten-free?
If you serve this pasta with a gluten-free certified noodle, then this recipe is gluten-free.
How to Make Vegan Pasta
Lots of the pasta recipes on Fit Foodie Finds are naturally vegan (hello garden summer pasta and pesto pasta) and we’re upping the anty with this recipe by making a creamy pasta sauce!
Soak Cashews Until Squishy
In order to make this a *creamy* vegan pasta sauce, you need cashews. Cashews take the place of any kind of cream or dairy because when blended, they turn into a super creamy consistency.
Soaking the cashews before blending is a must. Soaking your cashews in water helps soften them to make them easier to blend up as the base of your sauce. There are two different ways you can soak cashews.
- Overnight. Place cashews in a glass bowl and cover them with water. Cover with plastic wrap and let them soak overnight or for at least 12-24 hours.
- Flash boil. Bring a small pot of water to a rolling boil. Add cashews to the pot and remove from the heat. Let the cashews sit for at least 15 minutes.
No time? no problem!
You can always quick-boil your cashews instead of letting them sit overnight. This will speed up the soaking process.
Roast Veggies
Now it’s time to roast your veggies. The main components of this sauce are tomatoes, onion, and garlic. 3 of my favorite things.
Place veggies on a baking sheet and drizzle with olive oil. Season with salt and pepper.
Roast at 400ºF for 20 minutes.
After 20 minutes, carefully remove the skins of the tomatoes. Trust us, you don’t want to skip this part. Pop the veggies back into the oven and roast for 10 more minutes.
Blend Sauce
Once your veggies are done roasting, transfer them into a high-speed blender.
Drain the cashews from the water they were soaking in and place those in the blender too. Add olive oil, starchy pasta water, and salt and blend until smooth.
You may need to add more starchy pasta water depending on how thick/thin you like your pasta sauce, so make sure to save a full cup.

Can I sauté the veggies instead?
Instead of baking, you are more than welcome to saute the veggies. A few readers have done so and had success (re: comments).
We suggest sauteeing in a large frying pan until the tomatoes have broken down. Make sure to still remove the skins of the tomatoes as the texture will be better.
Serve and Top
Pour the creamy tomato pasta sauce on top of your cooked noodles and toss to combine.
Sometimes we’ve found that if you don’t work fast enough during the sauce creation, you may need to reheat it a bit. If that is the case, go for it! You can always add more starchy pasta water too.
Serve pasta with vegan parmesan cheese, fresh basil, and red pepper flakes.
Creamy Tomato Vegan Pasta
Ingredients
- 1 cup raw cashews
- 6 medium tomatoes, quartered
- 1 medium yellow onion, chopped
- 10 cloves garlic, peeled and smashed
- 1/4 cup olive oil, separated
- 1 teaspoon salt, separated (or more, to taste)
- 1/4 teaspoon ground pepper, + more for serving
- 1 cup starchy pasta water
- 1/2 tablespoon lemon juice
- 6-8 servings of pasta, we used bucatini
- Fresh basil, for serving
- Red pepper flakes, for serving
- Vegan parmesan, for serving
Instructions
- First, prepare your cashews by placing them into a bowl. Pour boiling water on top of them so that they are fully submerged. Let sit for 30 minutes.
- Preheat the oven to 400ºF and line a baking sheet with tin foil.
- Place tomatoes, onions, and garlic onto the baking sheet. Drizzle with 2 tablespoons olive oil and season with 1/2 teaspoon salt and 1/4 teaspoon ground pepper. Toss, making sure everything is coated.
- Roast veggies at 400ºF for around 20 minutes.
- While vegetables are roasting, prepare your pasta by following the direction on the back of the box. Make sure reserve 1 cup of starchy pasta water for later.
- When the vegetables are done roasting, remove the baking sheet from the oven and carefully remove the skin from the tomatoes. The skins should come off pretty easily at this point. Then, roast for an additional 10 minutes.
- Now it’s time to make your creamy vegan pasta sauce. Strain the cashews from the water they were soaking in and then place them into a high-speed blender.
- Transfer all ingredients from the baking sheet (including the juices) into the blender along with 2 tablespoons olive oil, 1/2 teaspoon salt, 1/2 cup of starchy pasta water, and 1/2 tablespoon lemon juice. Blend on high until smooth. Taste the pasta sauce and add more water as needed along with more salt.
- Toss the cooked pasta with the sauce. If it’s no longer hot, you can reheat on the stovetop.
- Servewith fresh basil, cracked black pepper, red pepper flakes, and vegan parmesan.
Tips & Notes
- Option to add fresh basil into the blender.
- This recipe was slightly updated on 2/9/2022. We added starchy pasta water to make it easier to blend along with a little lemon juice.

Our new go-to meal! The family loved it!
Thank you for sharing
tastes great! I cut the serving size to 1/3 and used cherry tomatoes and everything worked out great. I reccomend using less cashews to start, because the flavor can be a bit too nutty. Does anyone have any recommendations for additional ingredients or spices? I’m trying to make a more dynamic sauce.
Great recipe, I added some broccoli to the roasting veggies as it needed using up changed the colour a little but not the flavour. Mary
This recipe was absolutely delicious!!! Omg! My mom and I LOVED it!!! Thank you so much!
This sounds so delicious but my husband is allergic to nuts. Any suggestions for some other type of sauce? I’m very new at this type of diet.
Unfortunately, this is a nut-based sauce, so there are no good swap options!
I’ve made this recipe 3 times (in large batch) in the last 2 weeks since I discovered it. It’s seriously so so mindblowing, amazing! I do have some tips:
– I don’t roast the veggies since I use canned whole tomatoes (that’s what I have on hand atm). Less cleaning and still amazing flavor
– Since I don’t roast the veggies, I sauteed the onion and garlic for around 7 minutes on medium-high heat before adding the tomato. It burned the garlic a bit too much but the flavor is so much more complex with this slight burn.
– I make a huge batch of cashew butter using slightly roasted, unsalted cashew for this recipe and other recipes requiring blended cashew. It’s so fast this way, and I don’t feel lazy anyhow whenever a recipe calls for blended cashew.
– Just properly salting the pasta water is fine. I don’t think we need salt in the veggies.
– I add some pasta water and tonato paste or ketchup after adding the tomato and cashew butter. Creamy and packs a more tomato-y punch.
– I made a large batch of the sauce for meal prep, and boil just enough pasta everytime I want a portion. The sauce heats up very well once I mix it with al-dente hot pasta.
Thank you so much for this recipe. I love it so so much, and will definitely try the roasted version as soon as I cure my laziness and get my hand on some fresh tomatoes 😅
Thank you for all your tips!!! We’d love it if you could rate it using the star rating <3

We made this lovely recipe last night with tomatoes from the garden! I also roasted a bell pepper along with the other veggies and the cashew sauce turned out fabulous. We also used chickpea pasta (hello extra fiber and protein) and the hubs and I loved it. A small glass of pinot noir and a salad on the side and we had a feel good that we didn’t feel horrible about later. Thanks so much 🙂
YAY!! We’d love it if you gave us a 5 star rating!
Hi, made this cashew tomato sauce several times and love it..However decided to put chipotle in it and wow!! Used it as mayo substitute for tuna salad.. it was the best tuna melt I’ve had in along time!!
That sounds AMAZING.
This is delicious. We made this tonight and served over zoodles.
