Easy Soup Maker Tomato Soup

Tomato soup is a classic recipe that can be made in many different ways.

The great thing about this soup maker tomato soup is you can have it as it is or use it as a base to add some of your favourite ingredients to.

In my first Soup Maker Recipe Book (Amazon), I included my ‘Simple Tomato Soup.’ This recipe is very similar to that one, except in this one, I am using fresh tomatoes rather than tinned ones.

Plus, there are even fewer ingredients!

Tomato Soup Ingredients

  • 1 tbsp. butter/oil
  • 12 fresh tomatoes (I like to use on the vine or plum)

This makes a light and thin soup. If you like it thicker, check my tips further down.

How To Make Tomato Soup In A Soup Maker

ingredients for tomato soup

You can make tomato soup as simple as you wish. This tomato soup recipe is as easy as it gets. My super quick process was;

  1. Wash and chop up the tomatoes (leave skins on)
  2. Melt a little butter in the soup maker. You can even skip this step and head straight to step 4. You can use oil instead of butter.
  3. Add the chopped onions and let them gently cook in the melted butter (and really enjoy the smell of onions cooking in butter!)
  4. Add everything else to the soup maker. Stir to mix everything together. Set off on smooth.

If you don’t already have a soup maker and you’re tempted, you can read all about them in my guide to buying a soup maker. If you have any questions about them, please feel free to drop a message in the comments, and I’ll do my best to answer them.

What Type Of Tomatoes Should I Use?

My favourite type of tomato to use in a soup is either on the vine or plum. They need to be ripe for maximum flavour – they will have a little bit of give when you squeeze them.

If you are using tomatoes that aren’t ripe enough, you will end up with a soup that has less flavour – you can add in some tomato puree if this is the case. You can also intensify the flavour by roasting the tomatoes first in an oven.

How Many Tomatoes Should I Use?

The number of tomatoes you use will depend on the type, size and soup maker model you use. I tend to use anywhere between 8 and 10 – but sometimes more if they are small. I like to try and squeeze in a small chopped potato, too, to make the soup thicker.

Do You Need To Peel The Skin From Tomatoes?

I never peel the skin. Mainly because I can’t be bothered, but also because a lot of the goodness is in the skin and much of the flavour.

And, if you are using a soup maker to make tomato soup, it will blend it up so smooth that there won’t be any bits in it. A good hand blender should also get it smooth enough if you make it in a slow cooker or in a pot on a hob.   

Should I Use Fresh Or Tinned Tomatoes?

If you grow your own tomatoes, or it is tomato season, using fresh tomatoes makes sense over tinned. However, it’s not always possible to use fresh tomatoes, and having tinned tomatoes on standby in the cupboard is really handy. And they do still make a really tasty soup maker, tomato soup.   

Side Note: Check the sugar content of your tinned tomatoes – I’ve had a few people contact me to say that using tinned tomatoes has resulted in a burnt soup maker base.

I Don’t Like My Soup Thin, How Can I Make It Thicker?

This is a popular question I get asked all the time, so much so that I recently published an article with some tips on thickening up soup – How To Thicken Soup.

This tomato soup is light and great for a starter or a small afternoon snack. However, if you do want to make it thicker, you can;

  • add one medium potato, diced, at the beginning.
  • add two small carrots, diced, at the beginning.
  • add some rinsed red lentils (about 50g) at the beginning.
  • mix in some cream at the end.
  • mix in some instant mashed potato granules at the end. 

You will also find that it thickens up slightly when it has been left to stand.

Do I Need To Add Sugar To Tomato Soup?

You don’t need to add sugar, but you can. It will really depend on how tart the tomato soup tastes and whether you are adding any of the extras to your soup. If on tasting your soup it is a little bitter, add a pinch (or 1tsp) of sugar to sweeten it up a little.  

Added Extras

There are so many options to add to tomato soup. You can just leave it as it is or try any of the following;

  • garnish with fresh thyme leaves (basil leaves also work really well)
  • stir in some cream
  • sprinkle some chilli flakes over it
  • dip in some melted cheese on toast (this is amazing!)

Hi. Could I use pasatta & a tin of tomatoes if I don't have fresh tomatoes & if so how would I have to use or shall i just guess? Tomato soup is my absolute fav but want it to taste as near to the tinned version if possible tia. Ann.

@Liana Green, hi. I feel a bit ignorant by not replying but just seen your reply & thank you. I bought your soup maker book so thats maybe why I didn't get back. I had a go at making it with tinned tomatoes but even though I stirred it it stuck to the bottom, still tasted nice but much nicer with fresh tomatoes. I added some dried skimmed milk powder when it cooled to give it the creamy affect so it was really nice. Thank you 😊

Hi Ann - yes you can use tinned tomatoes/passata. A really simple one to use is one from my book: 1 onion, 2 garlic cloves, 1 potato, 1tsp mixed dried herbs, 2 x 400g plum tomatoes and 850ml vegetable stock. Make sure you give everything a good stir first as some tinned tomatoes/passatas have been known to burn the bottom of the soup maker jug. Hope that helps, let me know how you get on!

Hi Dayle - did you add in any seasoning at all? For that kind of soup I would probably try some of these; garlic, lemon/lime juice and maybe some herbs (dill or coriander would probably work well) - hope that helps, let me know how you get on!

It worked really well. I used 5 medium vine tomatoes and a Waitrose tin of chopped which had a natural flavour.

I saute'd the onion and used a finely diced potato to provide my desired thickness and a few small carrots for texture and flavour.. The consistency was fine, even though I removed no skins or peel.

For adjusting the flavour, I had no basil fresh, but used chopped parsley, sea salt, black pepper, two tsp sugar, and some Worcestershire sauce.
