Best Vitamix Tomato Soup (Vegan, Dairy-Free)


I absolutely love my Vitamix. It cost me a pretty penny but I use it all the time and have absolutely no regrets. For my full Vitamix review, click here. You can make so many things in it: smoothies, banana “nice cream”, sauces, and even hot soups. Yes, you can make a piping hot soup in a Vitamix without your stove or microwave. Today I am sharing my favorite Vitamix tomato soup recipe.

When I think of hot soup, the first thing that comes to mind is tomato soup. Growing up, I loved having tomato soup and a grilled cheese sandwich, especially on a chilly day. It’s a classic combo. The only problem is that most tomato soup recipes require milk, which is a problem if you do not consume milk! 

I’ve tried many vegan/dairy-free tomato soups and I often feel that they either lack flavor or creaminess. Well friends, I took matters into my own hands and came up with a tomato basil soup recipe that is vegan, dairy-free, milk allergy-friendly, and ALSO creamy and packed with fresh flavor. I know you will love this recipe!

The Ingredients for Vegan Vitamix Tomato Soup

We use several fresh ingredients combined with pantry staples in this recipe. Start with a base of canned diced tomatoes, then add oat milk, cashews, garlic cloves, nutritional yeast, sun-dried tomatoes, and seasoning blend. If you have fresh basil, I also highly recommend adding a few basil leaves as well. Fresh herbs are a great way to add freshness to a dish. In this case, basil pairs very nicely with the tomatoes.

If you are like me and enjoy your food a little spicy, you can throw in a pinch of red pepper flakes.

Although you can certainly substitute the canned tomatoes for fresh tomatoes in the recipe, I like how easy it is to just walk to your pantry and grab a can of tomatoes.

How to Make Fresh Tomato Soup in the Vitamix

If you are going to make this soup with fresh tomatoes, you can throw the whole tomatoes in, skin included. The Vitamix does a great job at blending peels and it will still be nice and smooth. Also be sure to use ripe tomatoes as they be much more flavorful and have a natural sweetness that pairs well with the savory ingredients in the soup.

How to Make Creamy Tomato Soup Vegan

How do you make dairy free tomato soup? It can be tricky making a creamy soup without milk, but it can be done. You won’t even notice a difference.

Most traditional creamy tomato soup recipes use dairy products such as whole milk, parmesan cheese or a swirl of heavy cream to make the soup creamy.

This recipe uses a combination of oat milk and cashews to make the soup creamy. If you don’t have oat milk on hand, you can use just water or vegetable broth instead. The cashews are what really makes this dairy-free tomato soup creamy.

If you are new to vegan/dairy-free cooking, cashews are often used to substitute for creamy ingredients. They can be used to make vegan cheesecakes, vegan cremas and aiolis, and sauces such as vegan alfredo and curry simmer sauces. 

How to Make Tomato Soup in a Vitamix

A high powered blender is best to make this homemade soup. What I love this recipe is that all you have to do is throw all the ingredients into the Vitamix container and blend! Make sure the lid plug for your blender is securely in place or some of the soup may splash out the top when blending.

If you have a model such as the A3500 that has a hot soup setting, all you have to do select this option and voila! Your soup will be ready in less than 7 minutes. 

If your model does not have a soup preset, start your blender on a setting of 5 (medium speed) for the first 30 seconds, then increase the setting to 10 (highest speed) and allow it to blend for an additional 5 minutes or until steamy hot. Season with additional salt and black pepper if desired.

Vitamix Blender Alternatives

Non-Vitamix Blender

If you do not have a Vitamix blender, you can use a regular blender. Most models will do an adequate job of blending the cashews. I used to make cashew cream in my little Magic Bullet blender! 

Whatever blender you use, just make sure you blend until the soup is smooth and does not have a crunchy or grainy texture. You will likely need to heat the soup in a saucepan on the stove if you do not use a Vitamix or comparable high-powered blender that heats the soup for you.

Immersion Blender

I do not recommend an immersion blender if you can avoid it. It can be very difficult to adequately blend all the ingredients in this recipe and distribute them evenly using an immersion blender although you certainly can try it!

Food Processor

I have not tried making this recipe in a food processor but I foresee that it would be difficult to get a smooth texture to the soup using this method. 

Vegan Tomato Soup FAQs

How do you make creamy tomato soup vegan?

To make tomato soup both creamy and vegan, you must avoid any and all animal products. In this case you cannot make your tomato soup with chicken broth or milk products and instead can use substitutes such as vegetable broth, cashews, and non-dairy alternative milks.

How do you make dairy free tomato soup?

If you plan on using a concentrate such as Campbell’s, I recommend using an unsweetened alternative non-dairy milk such as oat milk or soy milk. These vegan milks are thicker and will therefore have a more creamy consistency. Don’t make the mistake of purchasing flavored or sweetened non-dairy milks such as vanilla!

Can you use oat milk in tomato soup?

Yes. In fact, oat milk is my top pick for non-dairy substitutes in tomato soup. Oat milk is thicker than many other non-dairy milks and it has a relatively neutral flavor. 

How to Store Leftover Tomato Soup?

Store any leftover tomato soup in the fridge in an airtight container. I recommend storing in a glass container if possible.

How to Reheat Leftover Tomato Soup?

If you have leftover tomato soup, you can reheat it on the stove over medium heat. You can also reheat it in the microwave, but I recommend heating it in 30 second intervals, and stirring between each one. This will help prevent splattering and from the soup from getting too hot and sticking at the edges of the bowl.
