This dairy-free tomato soup is made using roasted tomatoes, fresh basil, caramelized shallots, & a few other key ingredients to give it a complex flavor (and canned tomato soup a serious run for its money).
This soup reminds me of the changing seasons. It holds onto the bright and rich flavors of summer but serves them up in a cozy twist preparing us for the colder months ahead.
Although it's still technically summer until the 22nd of September, fall has always been a favorite season of mine. Between the changing colors of leaves, sweater weather, warm baked apples with dairy-free salted caramel sauce, and the crisp air, I just love it all.
Ingredients For Dairy-Free Tomato Soup
- Roma tomatoes (also called plum) - the riper and juicier the better.
- Garlic cloves - to create the flavor early on.
- Shallots - caramelizing them first adds dimension to the soup.
- Tomato paste - helps give the soup a really concentrated tomato flavor and gives it lots of umami notes.
- Broth - either chicken or vegetable is great.
- Fresh thyme sprigs - add more flavor.
- Fresh basil leaves - give it freshness and goes so well with tomatoes.
- Olive oil - for roasting the tomatoes and also adding depth and richness to the soup.
- Salt & pepper - to taste.
- Dairy-free butter (optional) - gives it a richer flavor and creamier texture.
- Cashew cream (optional add-in) - if you want an even creamier soup.
Substitutions & Variations
Please remember that recipes are just a starting point.
How can you make this dairy-free roasted tomato soup using what you already have? Here are some ideas…
- No Roma or plum tomatoes? - use heirloom tomatoes if you have access to them.
- No shallots? - use a red, yellow, or white onion instead.
- No fresh thyme? - sub ½ teaspoons of dried thyme in its place.
- No tomato paste? - use 4 tablespoons tomato sauce or puree instead, but you'll have to cook it down a little longer to reduce it to have a similar concentrated flavor.
Frequently Asked Questions
When I first made this soup, my tomatoes were pretty unripe. So, to speed up the process, I put them in a paper bag and folded over the top, and left them on the counter for a couple of days. Once their skin had turned a deeper hue of red and they were soft to the touch, I knew dairy-free tomato soup was on the menu.
You can make this soup in a standup blender, just make sure to leave plenty of room at the top. Also, you'll likely have to do it in two batches.
The fresh basil leaves add another dimension of flavor to the soup that wouldn't be the same with dried basil.
