How to Make ‘No-Cream’ Creamy Vegan Tomato Soup
Man, oh man, do I LOVE a warm bowl of creamy tomato soup, particularly on a cold, rainy day. This super creamy vegan tomato soup is easy to make, incredibly flavorful, and perfect for any time of the year! It’s such a simple, comforting dish, especially when paired with a grilled cheese sandwich. That is a must, BTW. It’s a crime to eat one without the other!
The Secret to Making the Tomato Soup Super Creamy
It’s a combination of three things, actually—lots of caramelized onions, roasted garlic cloves, and a very long blending period. I only blend three cups of the soup base at a time, each for an entire minute at high speed. In this amount of time, the soup not only gets smooth, but it essentially emulsifies. The caramelized onions and roasted garlic cloves play a big part in emulsifying the soup, too, as they are secret thickeners!
The base of this vegan tomato soup is canned San Marzano whole peeled tomatoes. I highly recommend using these same cans of tomatoes, if possible! As silly as this may sound, I genuinely feel that their flavor sets themselves apart from other cans of tomatoes. These particular ones are sweet and rich in flavor, with low acidity. They also have a very tender texture, which is always good. I love them!

This Tomato Soup is FULL of Depth and Flavor
Some other key ingredients in this creamy vegan tomato soup are fennel seeds, caraway seeds, and fresh, whole basil leaves. I like to think of these as my three tomato soup musketeers. They pair so perfectly together!
Fennel seeds have a slight sweetness, with a strong kick of black licorice. Caraway seeds have a bit of a licorice flavor to them, too. But, mainly, they are sweet, with a hint of citrus and pepper. Lastly, the fresh basil adds another strong pepper punch, but with a nice touch of freshness. Despite these three ingredients having intense and unique flavors, they’re not overpowering whatsoever. They more so come together and elevate the taste of the tomatoes.

Top this baby off with lots of parmesan!
I almost always garnish my tomato soup with grated vegan parmesan and fresh basil leaves. If I don’t have store-bought vegan parmesan, I like to make a batch of my homemade cashew. It is SO delicious. It adds a subtle cheesy, and nutty flavor. The recipe is super simple and very quick to make, so I have written it below for you!
Cashew Parmesan Ingredients:
- 3/4 cup raw cashews
- 3 tbsp nutritional yeast
- 1/4 tsp garlic powder
- 3/4 tsp kosher salt
Cashew Parmesan Directions:
- Add all ingredients into a food processor and blend until it has a fine meal texture that resembles grated parmesan.
Hey! If you’re thinking about making this recipe, why not make my Super Easy Homemade Bread for Beginners!? It’s the bread I used for my grilled cheese in these photos. It’s so much better than store-bought bread, and it’s almost too easy to make!

No-Cream Super Creamy Vegan Tomato Soup
Ingredients
Roasted Garlic
- 1/2 cup peeled garlic cloves
- 1/2 cup olive oil, extra virgin
Caramelized Onions
- 3 1/2 cups yellow onion, julienned (About 2 medium-sized onions)
- 3 tbsp olive oil, extra virgin
- 1 tbsp organic cane sugar
- 1/2 tsp kosher salt
Soup Base
- Two 28 ounce cans "Cento" San Marzano organic, whole peeled tomatoes, please use these exact cans of tomatoes if possible!
- 2 cups vegetable stock
- 2 1/4 tsp fennel seeds
- 2 1/4 tsp caraway seeds
- 1 tbsp kosher salt
- 10 fresh, whole basil leaves
Instructions
Roasted Garlic
- Preheat the oven to 350 degrees Fahrenheit.
- Add the garlic cloves and olive oil into a tiny roasting pan. The garlic should be completely submerged in the olive oil. Wrap the top of the pan with a piece of plastic wrap and then with a piece of tin foil.
- Roast in the oven for 1 hour.
Caramelized Onions
- Add the olive oil into a large saute pan over medium-low heat.
- Once hot, add in the onions. Cook for 10 minutes, and stir occasionally.
- Add in the sugar and salt, and stir well. Cook for another 25 minutes and mix occasionally to ensure the onions do not stick or burn.
How to Cook the Tomato Soup
- Add all of the ingredients from the soup base, EXCEPT for the fresh basil leaves, into a large stockpot. Also, add the roasted garlic, including the oil it was cooked in, and the caramelized onions.
- Cook over medium heat for 12 minutes, and stir occasionally.
- Cover, reduce the heat to the lowest temperature, and cook for 45 minutes. Stir occasionally.
- Allow the soup base to cool down slightly, and then add the fresh basil leaves.
- Place 3 cups at a time into a high-powered blender. Blend for exactly 1 minute (This step is essential! The soup needs to be blended for a while to emulsify it, making it super creamy.). Next, pour the soup into a large container or another pot. Repeat blending 3 cups for 1 minute until there is no soup mix left.
- Stir the blended batches of soup together really well to ensure all of the batches are evenly combined.

This was SO GOOD. My husband doesn’t even love tomato soup and he was going back for seconds. Thank you for this delicious recipe!

I’m so happy to hear that, Emily! You know it’s a good recipe when someone who doesn’t even like that specific dish goes in for seconds! 🙂
Alyssa
Perfect recipe!

I know grilled cheese is the preferred combo with tomato soup, but I made this soup with the cheddar bay biscuits from this blog (make them!) and it was such a satisfying meal. This soup was so savory, rich, and creamy. Didn’t change a thing. Once my buscuits were gone I used a little bit of leftover soup to toss some penne in and it almost gave me a penne alla vodka vibe. Really, really delicious.

Ohhhh, what a fun combination, I may have to try that myself! I’m so happy you enjoyed both recipes! I also think I’m going to have to try your leftover soup/penne idea. That sounds delicious, and I love leveling up leftovers into a new dish!!

Mmm looks fantastic and today seems like a soup day! Do you peel your garlic cloves before roasting?
garden grub
Thank you! Yes, sorry, the garlic cloves need to be peeled before roasting. I will edit that into the recipe! 🙂
