Simple Garlic Rich Roasted Tomato Soup

This simple roasted tomato soup is the perfect way to use up tomatoes that are a little past their best. It is delicious, hearty and the perfect autumn belly filler!

With a little bit of extra effort you can elevate a simple roasted tomato soup to a whole new taste level with hints of thyme and lots of roasted garlic.

Simple Tomato Soup with Garlic Croutons.

This Soup recipe is firmly aimed at the lovers of two ingredients, tomatoes, of course, and garlic.

Now I have to confess I am not a garlic fiend, although fearless stunt wifey certainly is. I do like garlic but do often think it can be overdone and takes over many recipes.

However, when it is roasted it becomes mellow and almost sweet.

Offering a wonderful back note without being punched in the face with garlic! It is a technique I often use in recipes as diverse as this Roast Garlic Pasta recipe and this Vegetable Cous Cous Recipe.

Tomato soup is certainly one of those foods that I loved as a child. I could easily demolish a whole tin of the Heinz stuff with half a loaf of nasty white bread.

Another recipe I have turned from canned to home cooked is oxtail soup!

Fortunately, my tastes have evolved and my waistline does not reflect my youthful gorging.

This is a meal once again from our garden. We have scaled back from our earlier harvests of 250kg of tomatoes every year!

But we still grow more than enough to make up huge batches of soup. Not to mention gallons of tomato passata!

What Are The Best Tomatoes To Use?

We used to grow a dozen varieties of tomatoes, it is all very nice but I’ll let you into a secret. Batch preserving cherry tomatoes is an absolute nightmare!

The plants would inevitably fall over and we would end up with tomatoes growing all over the place!

We now stick to in the main to San Marzano plum tomatoes. They are the most wonderful all-round tomato with thicker flesh and fewer seeds.

Fewer seeds mean less water and more flavour.

Don’t worry if you can’t get San Marzano tomatoes, this soup will work with whatever you have but try and get tomatoes as ripe as possible.

It is an ideal opportunity to get all frugal and pop to the market or superstore late in the day. Look for the end of stock tomatoes that will be reduced in price.

Another great use for over-ripe tomatoes is a tomato consomme, which is something you simply must try!

The secret is that the riper the tomato the more flavour you will get!

Let’s face it they are getting roasted and blended, who cares how they look!

Where is the Basil?

“But Brian where’s the Basil” I hear you shriek, “Basil Schmazil” I say.

For me the only herb for my this soup recipe is thyme. In all fairness, I do think thyme makes everything taste great.

But I personally love the earthy, woody, almost minty flavour of thyme in a tomato soup.

I think it is just beautiful with roasted tomato and it is the perfect marriage with the subtle balsamic flavours I have going on.

What’s your favourite soup, tell me I’m always looking for new ideas!

  3. As each batch finishes add 1/2 Tbsp of the honey and swirl around to coat the tomatoes and then pour into a roasting tray
  4. Slice the onion into 8 wedges.
  5. Add the slices of onion to the same hot frying pan and repeat the process, turning them after 2 minutes each side
  6. Add the onions to the tomatoes.
  7. Deglaze the pan with the balsamic vinegar to caught bits from the bottom and then add to the tomatoes in the roasting tin.
  8. Add in the garlic cloves, thyme, salt and pepper.
  9. Roast in the hot oven for 45 minutes at 200°C or 400°F.
  10. When the soup has cooked blend it with a stick blender and then pass through a medium-fine sieve.
  11. Just before serving cut your bread into cubes and fry in butter and more crushed garlic until golden brown.


Serve with garlic croutons cooked in a mix of butter and oil and a drizzle of sticky balsamic sauce.

  1. Oh my! What can I say and where to start? This soup looks so delicious and having the privilege to make it from own grown tomatoes it’s just perfect. I so agree with adding thyme to it. What a lovely desirable and inspiring recipe. Thanks for sharing this Brian.

  2. This soup sounds wonderful, but I am definitely going to have to check out your sorrel soup. I planted some sorrel last year and it is flourishing and I have no idea what to do with it!

    • Ooo super, have fun, I always pair sorrel with spinach, because sorrel goes the most god awful colour when cooked, adding spinach and keeping the cooking time to a minimum will help with both the citrus flavour and stop you having a soup looking the colour of a 1970’s car 😮

  3. Wow This would be my favorite soup Brian, running to the kitchen to make it, the fam will love it! I’ll have to make it with the basil schmazil though as I’m out of thyme lol!

  4. My husband will be thrilled with this soup, you added thyme, he has planted time in every angle of the garden. Sounds delicious. My favourite, I too love soup all kinds.

    • Thanks Rosemary, thyme is such a wonderful herb especially at this ‘time’ of year, it works so will in this soup with the sweet rasted garlic and the balsamic 🙂

  5. Love that you’re a gardener! My husband is pouring over his Johhny’s seed catalog now looking for the San Marzano tomatoes! We know we want a fleshier variety for soups and sauce and salsa. Thought we’d try yours. The soup is an education in itself. Love the roasted garlic (although I’m with your wife “Bring on the garlic!”.
    We grow our own thyme which I use in everything. Basil turns into aphid food here. Thyme not so much. YAY, Dave found a San Marzano type greenhouse tomato! WHOOP! Next year’s variety for sure. Thanks so much for sharing. My favorite soup today is your tomato soup. Love the balsamic touch. It’s so good with tomato!

    • Teehee, I am a numpty gardener… I genuinely have no idea what I am doing but Mother Nature seems to be a kind mistress, we just chuck stuff in the ground show it a little love and she somehow provides us with plenty of bounty. San Marzano are a great variety for tomatoes, they have loads of flesh which makes for much better soups and sauces which we preserve loads of for winter, they are also really hardy and seem to last for much longer on the plant.

  6. This sounds amazing! I love that you added some honey in your soup, I will have to remember that! I so wished we lived closer because I would be knocking on your door bringing dessert for you and the wife right about now. 🙂

    • Thanks Tina, I always like to add a little sweetness when cooking with tomatoes and we get great honey from a chap in the neighboring village so it is daft not to use it… Just a we request though you posted this 12:23am my time so could you deliver my dessert a little later please 😀 😉
