Creamy roasted tomato basil soup with grilled cheese seems to be many people’s childhood favorite food. For me, growing up in a Korean household, I wasn’t familiar with this wonderful combo until later in my life. While I’m gluten free and mostly dairy free, I’m so excited that I could recreate yummy roasted tomato soup from fresh tomatoes, basil, and other healthy ingredients! And it’s paleo, Whole30, and vegan-friendly.

Vegan & Paleo Tomato Soup Recipe

While there are many easy paleo tomato soup recipes, I think the flavor is just so much better when you roast fresh tomatoes instead of using canned tomatoes. It’s actually easy and simple to make, without too many ingredients! It’s just so creamy and comforting, and I think you’ll love this oven roasted tomato soup. The leftovers are wonderful as well!

Ingredients in This Recipe

The ingredients list for this Whole30 and vegan roasted tomato soup is actually quite simple:

  • cherry tomatoes: You can use other types of tomatoes too. If you do use large tomatoes, make sure to cut them into smaller pieces before roasting.
  • garlic
  • onion
  • olive oil
  • salt & pepper
  • basil
  • bone broth, chicken broth, vegetable broth, or water: I personally like to use bone broth to add in some extra nutrients, but chicken broth works well too. If you are making vegan roasted tomato basil soup, you can use vegetable broth or water!
  • dried oregano
  • full-fat coconut milk: I prefer coconut milk since it’s so thick and creamy, but any other dairy free milk will work.

How to Make Roasted Tomato Soup

Here’s how to roast tomatoes for soup that’s packed with flavor:

  1. Preheat oven to 425 degrees F.
  2. In a large baking sheet, add cherry tomatoes, garlic, and onion. Drizzle with olive oil, salt, and pepper, then toss to coat.
  3. Roast for 30 minutes, shaking the pan halfway through.
  4. Cool for 10 minutes, then transfer all the contents to a food processor or a high powered blender. Blend until smooth, then add basil. Blend again.
  5. OPTIONAL: For an ultra creamy soup, pour the blended mixture through a medium mesh strainer. You can also do this if you don’t have an high-powered blender.
  6. Transfer to a large pot, then turn on heat to medium low. Pour in broth and oregano. Add more salt and pepper, to taste.
  7. Simmer covered for 10 minutes, then stir in coconut milk. Remove from heat.
  8. Serve this roasted cherry tomato soup hot, garnished with basil leaves and/or more coconut milk.

Frequently Asked Questions About Vegan & Paleo Roasted Tomato Soup

Do I have to use cherry tomatoes for this Whole30 tomato soup?

You don’t have to use cherry tomatoes. Bigger tomatoes like plum tomatoes will also work! I recommend cutting bigger tomatoes into smaller pieces before roasting.

How do I store and reheat leftovers?

Store this healthy roasted tomato soup in an airtight container in the fridge for up to 4 days. You can also freeze in a freezer-safer container for up to 4 months. Just don’t add any milk if you are planning to freeze, and make sure to leave an inch of room at the top.

To reheat, heat in a pot on the stovetop over medium heat until heated through.

What goes well with creamy roasted tomato soup?

Of course the classic answer is grilled cheese. However, if you are trying to keep it paleo, Whole30, and/or vegan, here are some other ideas:
– salad
– grilled or roasted chicken
grain free toast
paleo Irish soda bread
– corn
– baked potato or sweet potato
zucchini “corn”bread

    This was delicious! Thank you so much for a wonderful recipe! I didn’t have fresh basil so I used dried and I had unsweetened vanilla almond milk, so I used that and it was fantastic and you couldn’t taste the vanilla at all! Thank you again!
