This creamy vegan tomato soup starts with slow roasted tomatoes. Homemade tomato soup with your own homegrown tomatoes? That’s a long haul supper! I enjoy taking my time with things like this.

I’m a lover of intentional productivity, but I really can’t stand life hacks. I mean some of the little ones are useful. But when I think of hacks, I think of quick solutions, temporary slap dash jobs.

That “work smarter, not harder” advice seems to be thrown my way a lot. When I’m cutting lime wedges at work or filing papers and bills away, that advice inevitably comes.

I’m largely motivated by curiosity and personal or communal growth. I can’t help but take the long way around because getting lost in the journey is one of the perks of life! Devoting your time, your being, taking some necessary space, practicing, and then giving something your full attention doesn’t always get the job done quickly. But the experience and presence involved… that’s the ticket for me.

We’re not going to hack soup today. I slow roast tomatoes for over an hour here and then I purée them with cashews that were soaked ahead of time. And it’s seriously the creamiest, most comforting and nourishing bowl of tomato soup. It takes time, but it’s mostly inactive, so you can read a book or something while it’s all happening.

There’s a lot of recipes like this available online and in cookbooks, but I’ve already made this exact formulation a couple times. I think that always counts for something as far as sharing goes. We had a cool snap over here, which made for some slowly decaying tomato plants and an urgency to get the fruits picked and preserved. Basically the best possible timing for a cozy, homemade tomato soup. To slower days and lots of soup ahead!

Prep Time: 20 minutes
Cook Time: 1 hour
Total Time: 1 hour
Servings 6

Ingredients

  • 4 lbs tomatoes
  • 3 shallots, peeled
  • 4-5 cloves of garlic, peeled
  • 2 teaspoons fresh thyme leaves
  • 1-2 tablespoons olive oil
  • sea salt and ground black pepper, to taste
  • ½ cup raw cashews, soaked for at least 2 hours and drained
  • 1 tablespoon tomato paste
  • ½ cup basil leaves, packed
  • 2-3 cups vegetable stock
  • 1 tablespoon balsamic vinegar

Equipment

Notes

  • If you don’t have cashews or forgot to soak them, feel free to use some full fat coconut milk instead–about a 1/2 cup. This will change the flavour a bit, but you could totally go on a little flavour tangent and roast the tomatoes with some cumin and coriander seeds, maybe some chili too.
  • Also, I puréed this in a high speed blender, which might account for the serious creamy-ness. I think similar results are possible with an immersion blender or food processor though.

Instructions

  • Preheat the oven to 350°F. Line a large baking sheet with parchment paper.
  • Cut any large tomatoes into quarters. Cut medium tomatoes into halves and leave any cherry or grape tomatoes whole. Spread them out in a single layer on the baking sheet with any cut sides facing up. Cut peeled shallots into quarters and nestle amongst tomatoes. Stick garlic cloves into juicy spots of tomatoes or nestle them between cut tomatoes like the shallots (just to avoid burnt and bitter garlic).
  • Scatter thyme leaves on top of tomatoes. Drizzle the olive oil over the tomatoes, shallots and garlic. Season everything with salt and pepper and slide the tray into the oven. Roast for about an hour, or until the tomatoes have shrivelled up a bit and the shallots are soft. Let cool slightly.
  • In batches, blend the roasted tomatoes with the soaked and drained cashews, tomato paste, basil, and vegetable stock until you have a smooth purée. Pour blended soup into a large pot.
  • Once you've blended everything, including the accumulated juices in the baking sheet, add the balsamic vinegar to the pot. Bring the soup to a boil, check it for seasoning and adjust if necessary. Serve the soup hot with extra basil and olive oil drizzles.

    Amazing creamy tomato soup!! Roasting the tomatoes really elevates this recipe and also keeps the prep/cooking time pretty hands off. This soup has a wonderful velvety texture and it’s such a treat with freshly harvested tomatoes from the garden. I’ve made this recipe a few times now and it always hits the spot.

    Made this yesterday as meal prep, so I haven’t tried it yet (other than the usual taste testing for flavor balance), but I just got a text from my husband who had it for lunch at work: “Hands down best tomato soup of my life. Not worth it if it took forever but by golly was it delicious :-)”
    This is super high praise coming from him, so I’m looking forward to my bowl later. Lucky for us, it’s really simple and mostly hands off to prepare. Now I just need to get my hands on more tomatoes…
    Thanks Laura for another fantastic recipe!

    Simple and delicious! I roasted everything in the oven then blended and cooked it using my Vitamix (soup setting) so it was extra easy and an even easier clean-up!

    QUESTION: (disclaimer, I’ve not made this tomato soup yet). Summer has ended and extra tomatoes were made into LOTS of puree now in my freezer. Is there any way to utilize the tomato puree as opposed to roasting fresh tomatoes? What quantity might be used in place of roasted tomatoes? PS would LOVE to see a “search” feature on your comments.

    • Laura

      Hi Kim,
      So when I’ve canned tomatoes before, I accounted for 2.5-3 lbs of fresh tomatoes per quart jar. With this in mind, I think 4-ish cups of purée will do the job in this recipe.

    I have loved every recipe of yours that I have tried, can’t wait to give this one a go! Questions: Can I mix in yellow tomatoes with red in this recipe? A neighbour gave me more than I know what to do with. Will it effect the flavour much? Approx. how much is 4 lbs of average sized tomatoes?
    Thanks so much!

    • Laura

      Hi Jena,
      Yellow tomatoes will be totally fine here. They’ll only change the colour a bit. And after some googling, it looks like 4 lbs is about 12-15 average-sized tomatoes ;)

    Just made this soup this morning since we have a ton of heirloom tomatoes and it is crazy good!! my husband, who isn’t a ‘soup’ person absolutely loves it!! thanks :)

  • Malin Andersson

    I love all your vegan recipes. I have made this recipe for my son and he loves it so much. I am very thankful to you for this amazing vegan soup recipe.

  • Anders Svensson

    Tomato soup is extremely delicious and tasty. I have already tried it and it was great. Please share some more recipes about tomatoes. Thanks for sharing delicious recipes with us.

  • Malin Andersson

    Last night I made tomato soup for my daughter. It was made very tasty. The addition of cashews in the recipe is a brilliant idea. What a wonderful and healthy way to make it creamy. Thanks! I’m anxious to try more of your recipes.

  • Food's Not Dead

    Must try !

  • Mikkel Magnuson

    Hi I just made this tonight for my wife who was feeling under the weather today and I wanted something that wouldnt be to heavy. Also…I have never had tomato soup. Oh my goodness I am a fan now! I made it using your recipe instruction and my husband said that it was by far the best tomato soup he’s ever had! Thank you so much! Will definitely be making this again…was super easy too!

  • Melissa Diehl

    Hi. Made this soup, so very good, thanks! Do you have nutrition info for it?
    Thanks.

  • Gina

    Hello. Just discovered your interesting blog–how have I not seen it, for all the time (a fair amount; too much) I’ve spent perusing vegan/healthy cooking blogs during the past several years. Glad to know about it.

    Although I want to try so many of the recipes I’ve checked out in your recipe section, the impetus for this comment is this: The photo of your tomatoes, on the baking tray, pre-roasting, is the most beautiful photo of fresh tomatoes I have ever seen. To call them ‘gorgeous’ is not adequate to describe the beauty of that photo.

    Thanks!

  • Annie

    Second time I’ve made this recipe, and as delicious as ever. Have you ever tried freezing it? It would be a great meal to have on hand on busy days, alone or over pasta. Thanks! :)

    • Laura

      Hi Annie! I haven’t tried freezing this one, but I think it should be fine. The cashews provide a good amount of fat to help preserve the soup in the freezing process. Let me know how well it works if you try it!

    I made this last night after a request for tomato soup from my daughter. It was delicious and I’m sure will be on heavy rotation in our house. The addition of cashews is brilliant. What a wonderful and healthy way to make it creamy. Thanks! I’m anxious to try more of your recipes ;)

  • Molly

    I just made this in the dead of winter and it was incredibly flavorful and a beautiful creamy texture. I might make it again without the broth as a decadent pasta sauce. Thank you!

  • carmit levin

    hi! i love your tomatoes photo and I just found your blog. would you mind if I reposted it from the pinterest page to our facebook page? thanks! Carmit

    • Laura Wright

      Hi Carmit, that’s totally fine! Thanks for asking.

  • 4myveggies

    Thanks for yet another wonderful recipe :)

  • Marta Potoczek

    It’s so nice to find someone with similar love for growing veg. I can see our similar love for tomatoes and kale as my veggie patch looks so alike! Huge hugs.

  • Borough 22 Brownies

    Yep. Making this one too! Yummmers!

  • Samantha Attard

    Hi Laura!

    1. Love the sentiment about the life hacks (and agreed…talking instead of assuming is a really good idea). Totally appreciate that your delightful response is to make food very slowly. Awesome.
    2. I am so impressed by your garden!! Your kale is out of control.
    3. Thanks for another delicious looking recipe. I look forward to trying my hand at it!

    Have a great day,

    Sam
