Why this recipe works
Tomato and Basil are the perfect combination of ingredients that make the best bowl of soups! The taste and sweetness from the roasted plum tomatoes is so comforting and a recipe you’ll make all the time.
The depth of flavor this dairy-free tomato and basil soup packs with so few ingredients is impressive and they’re likely already in your kitchen!
You can always freeze this roast tomato soup down, so make some extra and use it for a quick and healthy lunch during the week. This soup was inspired by my Easy Red Pepper and Tomato Soup recipe as it was so popular.
Ingredients to make Roasted Tomato Soup
- Large Tomatoes – form the base flavour of this roasted tomato soup recipe. You could also use cherry tomatoes, roma tomatoes or fresh garden tomatoes.
- Red Onion – especially when roasted – adds a delicious flavour.
- Garlic Cloves – are one of my most commonly used flavours.
- Oregano – This Italian seasoning pairs perfectly with the other flavours in this roasted tomato soup.
- Fresh Basil – and oregano go hand in hand!
- Olive Oil – is used to roast up the veg and garlic.
- Vegetable Broth/Stock– turns these roasted veg into a soupy consistency.
- Salt and Pepper – help to accentuate the flavours in this dish.
See recipe card for full information on ingredients and quantities.
Substitutions
- Garlic Cloves – if you only have minced garlic, it will do, but it won’t bring the same flavour as roasted garlic.
- Vegetable Broth – You could swap for chicken broth/stock if you prefer.
- Fresh Basil – you can use dried basil if needed.
- Olive Oil – is my flavour of choice for roasting these vegetables, but other oils will also work.
- Fresh tomatoes – if you fancy making a tomato soup without fresh tomatoes then try my 10 Minute Tomato Soup which uses passata.
Variations
- Spicy – Add sriracha or red pepper flakes while cooking to make this a spicy tomato and basil soup.
- Deluxe – To bring the plating of this homemade tomato basil soup up to the level of gourmet fine dining, stir in some vegan or heavy cream and garnish with fresh basil. Bon appetit!
- Kid friendly – While kids may not be willing to dive into a fancy roasted tomato basil soup, serve it up with a grilled cheese sandwich or something else to dip it in, and they’ll be sold!
How to make Roasted Tomato Soup
Step 1: Slice the tomatoes into halves and onion into quarters.
Step 2: Place onto an oven baking tray (tomatoes sliced side facing up), along with garlic cloves. Drizzle over the olive oil and sprinkle the dried oregano on top along with a couple pinches of salt & pepper. Roast for 1 hour at 160C.
Step 3: Remove from the oven and scrape the ingredients from the tray into a large pot. Add the stock along with the handful of fresh basil leaves. Bring to boil on the stovetop over a medium heat and then allow to simmer for 10 minutes.
Step 4: Now just hand blend until smooth (or transfer to an immersion blender).
Hint: Don’t skip squashing the garlic cloves. It takes off the skin and allows the flavour to come out.
Leftovers
Leftover roasted tomato basil soup can be stored in an airtight container in the fridge for 4-5 days. You could also freeze it. I recommend freezing it in small cups for individual servings. Allow to thaw and then reheat in a pot on the stove. You can also enjoy it chilled.
Recipe FAQs
For my tomato soup with fresh tomatoes recipe, I like to roast my fresh tomatoes first, along with onions and garlic. I then combine it with stock and basil and cook it on the stove.
It can! This tomato basil soup recipe will keep in the freezer for up to three months. You can store it in an airtight container as a whole or in individual servings. Allow to thaw and then reheat on the stove.
You can definitely make a good tomato soup recipe without roasting the tomatoes. Roasting the tomatoes, however, enriches the flavour so much! It adds an amazing caramelised flavour that adds so much to the soup!

The flavour in this soup was unbelievable! Really easy and delicious, will be making it again!
Thank you Francesca 🙂
Absolutely delicious. I made 2 small additions that keep it still vegan & gluten free. I boiled a potato and blended it with my tomatoes to bulk it up and thicken it and added nutritional yeast for the obvious amino acids and B vitamins, but it also gives it the most sublime flavour. I often use it in tomato based Italian dishes or if I need a “cheese” sauce
Thank you 🙂
AMAZING flavour! Loved it 🙂
Absolutely love this soup, took it in for my work colleagues and they absolutely loved it.
Lovely soup even my husband liked it and he doesn’t like tomato soup
