Oven Roasted Tomato Soup

I just finished bringing in the last of my tomato harvest, and not a moment too soon, since we had a large wind and rain storm over the weekend. This gives me the perfect opportunity to make this delicious Oven Roasted Tomato Soup. Roasting the tomatoes helps bring out some of their natural sweetness and creates a more robust flavour.

Roasting all the soup ingredients also makes this a very easy soup to make, since you simply have to roast all the vegetables until dark golden brown, then place them in a pot with some chicken stock, herbs and wine, simmer and puree! It’s a great soup to make ahead and freeze, either in vacuum sealed bags or other containers and then enjoy on a cold fall or winter’s evening when you don’t necessarily feel like cooking a big meal.

Oven Roasted Tomato Soup

For this recipe you will need :

  • 4-6lb Fresh Tomatoes
  • 8 Garlic cloves
  • 3 Carrots
  • 3 Medium Onions
  • 1 cup Chicken stock
  • 2 Tbsp Honey
  • 1 bunch Lemon thyme
  • Salt and pepper
  • Olive oil
  • A splash of 35% Cream

To start, wash the fresh garden tomatoes in cool water to rinse off any small insects and dirt that might be hiding in any crevasses. I simply run mine under cold water and rinse by hand. Peel the onions and garlic and along with the washed tomatoes rough chopped these to help evenly roast them. They don’t have to be very small pieces. Two or 3 inches in diameter, you don’t want the tomatoes to disintegrate as they roast. As long as everything is about the same size, the vegetables will roast evenly.

Place all the chopped vegetables in a roasting pan, drizzle with olive oil and season with salt and pepper. It is important when making soups (and any other dish really), to season as you go. Adding salt and pepper at various stages of cooking will help develop the flavours of what you are cooking and lower the chance of over seasoning at the end.

Roast the vegetable mix at 375F until everything is starting to turn golden brown. The oven roasted tomatoes will give off quite a bit of juice as they
roast, which I simply poured into my soup pot for added flavour. Dump the roasted vegetables into a regular pot, add the sprigs of lemon thyme, honey, wine, and stock and let it come up to a boil. Lemon thyme is available in the spring at some nurseries. Plant it early enough and it will be well established by the winter to give you a decent harvest the following year.

Turn the heat down and let simmer for 30 to 40 minutes uncovered. Once the soup has simmered, taste the broth to see what the general flavour is like. Can you taste a hint of the thyme? Is the oven roasted tomato too acidic, if so add some more sugar or honey. If the flavour is a little underwhelming, add a little more salt and pepper.

Puree the soup, using either an immersion blender or other piece of equipment suitable for this. I am using a nutri-bullet style blender and puree ingredients in batches. You should be able to get the soup to a completely smooth texture, though you can leave it slightly chunky for a more rustic look and feel. If you are puree ingredients until completely smooth, I would recommend adding a cup of 35% whipping cream to the soup, it will add a velvety mouth feel to the soup and cut any acidity the tomatoes may have given to the soup (tomatoes are naturally acidic). To ensure 100% smoothness you can also strain the soup through a chinois or fine mesh strainer to remove any little flakes of tomato skin that may not have been pureed.

Return the oven roasted tomato soup to the pot (making sure to rinse it first to avoid reintroducing chunky particles of food), and bring to a boil. Turn the pot off and season the soup to your liking.

To serve the soup I recommend garnishing with a little dollop of creme fraiche, which can be made at home or store-bought and drizzled with a colourful oil such as this green chive oil or some balsamic vinegar. You can also use tomato blossoms in summer to garnish the soup or other edible flowers if you like.This Oven Roasted Tomato Soup with a hint of lemon thyme takes the classic recipe to a new level. Sweet and packed full of tomato flavor, this makes a great appetizer or re-heated for lunch,

  1. This sounds really wonderful. The photo in the post looks like you roasted the thyme as well. Is that correct, or just add it to the soup? Also, could you roast the garlic as a whole head?
    If I have already roasted garlic in my fridge, how would I have stored it, and how long will it keep?

  2. I love that you roasted your ingredients for this recipe!! I bet the flavours got really concentrated and you got a touch of caramelization in there as well. I definitely will have to give this a try with my next batch of tomatoes! 🙂

  3. This looks REALLY good. Like, really really realllllly good. I love that you’ve roasted the tomatoes along with all of the other components too! The depth of flavour must be spectacular. I’m totally going to have to take a stab at this too – of all the tomato-based things I’ve done, I have yet to actually make a tomato soup. And by the way, I LOVE the way you’ve plated this. Soups can be so hard to shoot in an interesting way, but you’ve really done a great job.

  4. Love it. I have been playing chicken with my garden and thankfully the frost hasn’t arrived yet and my tomatoes are still growing. It has been a crazy year, for sure. This soup looks like a great way to use up the glut of tomatoes.

  5. Wow, this soup looks absolutely fantastic! Love the combination of things that goes into it – going to try this one out this weekend! Thanks for sharing.
