tomato sauce rigatoni pasta on a white plate with a fork

A simple tomato pasta sauce with tons of hidden veggies. The tastiest and easiest way to sneak some veggies into your diet!

This simple blender sauce is made by simmering lots of delicious and nourishing veggies, then blending them until super smooth. I use my tried and true Vitamix for this sauce (and all of my blender sauces), for the best creamy texture.

You wouldn’t believe how easy it is to make a sauce from scratch like this! Once the veggies are chopped, it’s just a quick sauté, simmer, and blend. That’s it! A huge bonus: this sauce makes a lot, and is perfect for enjoying some right away, meal prepping some for the week, and/or storing some in the freezer to save time on meals later!

You guys know I love my pasta sauce recipes, and I never get tired of sharing new ones with you! Pasta is such a comforting and delicious meal to make at home, and I find there are so many ways to easily up the nutrients while still tasting delicious. This sauce has carrots, peppers, and celery hidden in it for tons of vitamins, minerals, and fiber added to the sauce. Additionally, onions and garlic also provide more than just flavor- they are sources of prebiotic fibers to add to your meals that can be beneficial for gut health!

As for the noodle, I used a gluten free chickpea rigatoni pasta here. You can really use any noodle you like, or even spaghetti squash! This recipe really just provides you with a delicious tomato sauce to use any way you’d like!

  • Prep Time: 20 minutes
  • Cook Time: 40 minutes
  • Total Time: 1 hour
  • Yield: 8 cups of sauce 1x
  • Category: Lunch, Dinner


The best simple tomato sauce with tons of hidden veggies! Vegan, gluten free, and nut free. 


  • ¼ cup extra virgin olive oil
  • ½ medium yellow onion, finely diced
  • 2 bell peppers, diced
  • 3 stalks of celery, diced
  • 45 large carrots, diced
  • 4 cloves of garlic, minced
  • 1 tbsp Italian seasonings
  • ½ tsp sea salt, plus more to taste
  • ¼ tsp black pepper
  • ¼ tsp red pepper flakes
  • 3 tbsp tomato paste
  • ½ cup dry red wine (optional, but adds some extra flavor)
  • 2 (28 oz) cans whole peeled tomatoes and their juices

Optional Vegan Parmesan for Serving:

  • 1/4 cup raw cashews
  • 2 tbsp hemp seeds
  • 1.5 tbsp nutritional yeast
  • 1/2 tsp sea salt
  • 1/8 tsp garlic powder


  1. Heat a large pan with high sides over medium heat with the olive oil. Once hot, stir in the onion, peppers, celery, carrots, and garlic. Stir in the Italian seasonings, salt, pepper, and red pepper flakes. Allow to cook, stirring occasionally, for 10-12 minutes, until veggies are soft.
  2. Stir in the tomato paste, then allow to cook down for 3 minutes. Pour in the red wine and again allow to cook for for 3-4 minutes.
  3. Stir in the tomatoes and their juices, slightly breaking up the tomatoes. Allow to simmer for at least 40 minutes
  4. While veggies are simmering, make the vegan parmesan (optional). Add all parmesan ingredients to your blender and pulse until a fine crumb is created. Be sure not to over blend into a paste. Set aside in a small bowl.  
  5. Carefully spoon the sauce ingredients into your Vitamix, then blend until super smooth. Depending on the size of your Vitamix, you may need to blend in batches.
  6. Return blended sauce to your hot pan while you cook your pasta of choice before mixing with sauce and serving. *Note, this can also be served with any protein, veggies, or spaghetti squash instead of pasta!

Did you make this recipe? Be sure to tag @gatherednutrition on INstagram so I can see what you made! Leaving a rating and review on the site is a huge help too!

  1. Hannah says:

    Just made this tonight and it’s easily one of the best, creamiest sauces I’ve ever made. So easy, got to use up all of my veggies that were about to be past their prime (I added in some spaghetti squash and zucchini bc why not?!) and it came out SO good!!!! I will be saving the rest in the freezer and enjoying all December 🙂 10/10, amazing!

  2. Sophie says:

    I stuck to the recipe, and did not like it at all. It took forever to make and no one in my family liked it. Not impressed:( and it was too spicy??

  3. Hayley says:

    I made this sauce and added grass fed ground beef. Had it with egg pappardelle and I swear it tasted better than in a restaurant. Didn’t even add cheese it was so good! Very worth it.

  4. Colleen says:

    10/10 will definitely be making again! So flavorful and I love the extra veggies in here! Delicious

  5. Jamie says:

    Easily the best sauce I’ve ever made! Thank you for sharing this recipe!

  6. Kellen says:

    This was a great sauce, pretty simple, and so many hidden veggies! Love that I can make a bit batch of it to have for meal prep or keep in the freezer.

  7. Britt says:

    This was so easy to make and was absolutely delicious! Definitely going to freeze some to save for the future.

  8. Taylor says:

    So yummy! Made it for my boyfriend and he loved it! This recipe is definitely a keeper 🙂

  9. Cindy Alvarado says:

    Loved it! Great way to get veggies in my diet and this makes so much so it’s perfect for leftovers! It’s not easy finding gluten and dairy free recipes! So thank you!!!

  10. Maureen says:

    SO good and so simple!!! Definitely a go to when I have extra veggies on hand to get rid of or if I’m just in the mood for some extra vegs!!

  11. Danielle Wrubel says:

    So delicious and a genius way to sneak all the veggies in!! I used Meiomi Pinot Noir and it gave such an amazing flavor! However, next time I will definitely be halting the recipe because it did make soooo much sauce!! This sauce is going to be a staple for college meals!!

  12. Megan says:

    If we don’t have a Vitamix can I use a Ninja Blender and it will work the same?

  13. Angela Augusta says:

    This is the best sauce I have made, and its vegan! The avocado is a genius idea to getting a rich and creamy sauce, it was very reminiscent of the Gigi Hadid spicy vodka sauce, without the vodka and heavy cream! so beyond impressed. Keep it up girl! I love your recipes and ideas.

  14. Natalie says:

    Made this tonight with a dry white wine instead of red ( it’s all I had that was vegan wine!) and it was still delish! so creamy and full of nutrients <3

    • Mia Swinehart says:

      Yum!! So glad you loved it Natalie! xo

      • Melissa Mazepa says:

        I made this last night and brought some to a couple of my friends and it was an absolute hit! Everyone loved it, and now i’m eating the leftovers for breakfast! I will definitely be trying more of these recipes! Thank you!

  15. Libby T says:

    My family loved this! I tasted the sauce after blending and was actually a little unsure, but the cheese at the end completely pulled it together – so healthy yet hearty! I will say that this recipe made SO MUCH sauce, I ended out freezing half for another meal as there was no way we could finish it off in one sitting 🙂

  16. Hailey Stoltenberg says:

    I had no idea that this would taste so good. I was short on time, so I only put 1 can of tomatoes in to simmer but otherwise kept the recipe the same. It came out thick (which I personally like) and literally tastes like red pepper sauce. Best way to get my boyfriend to eat his vegetables lol

  17. fibi says:

    can I use only one can of the tomatoes or would it not work out?
