The BEST Tomato Soup!

Is there ever a time that isn’t appropriate for tomato soup!?  Serve it as a starter, devour a huge bowl for lunch or dinner, when you’re feeling ill, if you’re cold, the list goes on. Whenever you need it, tomato soup has always got your back. And bread too. Bread is always good.

So, what makes the best tomato soup?

For me there’s 3 crucial factors to making the most delicious tomato soup:

  1. Fresh Tomatoes – There’s just no comparison in using fresh tomatoes to canned tomatoes. The tomato is the hero ingredient so scope out the most gorgeous fresh tomatoes you can.
  2. Roasted Tomatoes – By chucking the tomatoes in the oven beforehand, you get this yummy sweetness from the caramelization which adds heaps of flavour to the soup. Just like the fresh vs canned, there really is no comparison to boiled vs roasted.
  3. Basil – Tomato soup with basil is just like salt and pepper. A marriage we are not here to break up.

Roasted Tomato Soup

Roasting the tomatoes is an incredibly important step in this tomato soup. By roasting the tomatoes you gain a deeper tomato flavour that fresh un-roasted tomatoes can’t quite deliver. You’re left with a rich and sweet tomato flavour which when turned into a soup, is to die for!

What type of tomatoes are best for soup?

Roma tomatoes work great, as do vine tomatoes and plum tomatoes. In any case just make sure they’re fresh and ripe tomatoes. If the tomatoes are under-ripe (green tinges) the soup will be slightly bitter.

Do you need to peel tomatoes for soup?

Because you are going to be using a hand blender to blitz the soup, you do not need to peel the tomatoes before or after roasting. If you want a completely smooth soup, you can strain it through a sieve. I quite like the rustic texture of soups, but completely down to preference!

How to Roast Tomatoes for Soup (quick summary)

  1. Slice tomatoes in half and place flesh side up on a tray. Generously sprinkle with salt and pepper, then flip back over.
  2. Drizzle with olive oil and throw in some garlic and thyme.
  3. Roast in the oven until wilted and lightly charred!
Top Tip – Roast the tomatoes low and slow for a deeper, more caramelized flavour.

How to make Tomato Soup

Alrighty, so we’ve got some gorgeous roasted tomatoes, let’s talk soup. Here’s a few simple but crucial tips for making the best tomato soup:

Caramelizing the Onions

You’ll want to fry your onions off in butter at a low heat for at least 15-20mins. This will caramelize them and tickle out the sweetness. Those soft buttery onions are gonna add a gorgeous base flavour for the soup.

Tomato Puree (Tomato Paste in US)

A nice dollop of tomato puree will not only add a deeper colour to the soup, but also enhances the tomato tones of the soup. It’s important to fry the puree, so it caramelizes and takes the bitterness of it.

How long to simmer soup?

You can simmer soup for anywhere between 20mins and 3 hours. The longer you simmer, the deeper the flavours. For this recipe I go for around 30mins as the tomatoes have already spent 30mins caramelizing in the oven. But, feel free to simmer for longer! Just remember to keep the lid on as you simmer so the soup doesn’t reduce.

How to make Roasted Tomato Soup (quick summary)

  1. Fry onion in butter and caramelize.
  2. Stir in tomato puree then deglaze with balsamic vinegar.
  3. Pour in roasted tomatoes (with pan juices) and garlic (removed from skins).
  4. Add fresh basil and stock and simmer.
  5. Take lid off and blitz with hand blender.
  6. Test for seasoning and thin out with stock if needed.

How to make roasted tomato soup with fresh tomatoes and basil - step by step

Do I have to sieve tomato soup 🤔 – For me there’s no need to use a sieve when making soup. I feel you lose that classic homemade texture when you push it all through a sieve, I much prefer a soup with a bit of ‘bite’ to it than a completely smooth soup. But hey, each to their own!

How to Serve Tomato Soup

This recipe will serve 4 as a main or 6 as an appetizer/starter. Serve it nice and hot fresh from the pot with a little extra garnish on top.

Tomato Soup Garnish Ideas

  • Sprig of Thyme
  • Drizzle of Extra Virgin Olive Oil
  • Pinch of Cayenne Pepper/Chilli Flakes
  • Cracked Black Pepper
  • Drizzle (and just a drizzle) of Cream

The little things really make a difference when dressing up a soup. Plus, all the above with actually enhance the flavour of the soup. You know, not just a pretty face and all.

Notes:

a) Best Tomatoes for Soup -Β Roma tomatoes work great, as do vine tomatoes and plum tomatoes. In any case just make sure they're nice and ripe, if they're under ripe (green tinges) they'll be slightly bitter and throw off the flavour.
b) What to serve with Tomato Soup? - I like bread 'n' butter, grilled cheese, cheesy pesto garlic bread or just some parmesan crisps.
c) How to garnish a Tomato Soup? - Ideas include: a drizzle of extra virgin olive oil, a sprig of thyme, a pinch of cayenne pepper/chilli flakes, cracked black pepper or a small drizzle of cream.
d) Do I have to fry the tomato puree? - The change in taste after you cook off tomato puree is crazy. Really enhances that deep tomato flavour. Once you've fried it just make sure you deglaze the pan. Here I use a small splash of balsamic vinegar.
e) Roasting Tomatoes - If you've got time, then lower the temp and cook longer for a deeper caramelization of the tomatoes. This will really intensify the flavours.
f) Caramelizing the onions - It's important to cook the onions slow 'n' slow to really caramelize them. You want that sweet, buttery goodness.
g) Roasted Garlic - I have actually be known to put a whole large bulb of garlic in this (because I love the stuff). Roasting the garlic actually takes the pungency out of and it turns it sweet, so don't be afraid to chuck in an extra few cloves and create a delicious roasted tomato and garlic soup πŸ™‚
h) Serving & calories - It would feed 6 as a starter or small lunch, 4 as a main. Calories based on a division of 6, assuming 1.5 tbsp olive is used in total.Β

    I can’t have garlic so I used roasted red peppers. This was super yummy as well as fun and easy to make.

    Love this recipe; have made it twice so far. First time I added a little too much garlic so the garlic was a little overwhelming, but second attempt I scaled it back a little and it tastes fantastic!

    I made this yesterday for my husband and I to have for lunch today. It was amazing although half way through it got a bit sickly. Any ideas how to tone that down a bit? Will definitely be making this in batches and freezing πŸ™‚

      Hi Mel, so glad you enjoyed! With regards to it getting a little bit sickly, it’s not something I’ve experienced before, but it could potentially be the stock you used? The stock makes up a good part of the soup so if that’s a little sickly to begin with it may have had a knock on effect. You could try thinning it out a little or even switch and use vegetable stock if you originally used chicken. Hope this helps!

    Roasted tomato soup is one of my favorite fall dishes to make. I like that you leave your garlic skin on while you roast them. I’ve heard that is the best way to impart the flavor into the dish to the max!
