Slow Cooker Carrot & Coriander Soup

A glorious, flavour packed carrot and coriander soup made in a slow cooker.

Slow Cooker Carrot & Coriander Soup

I love my slow cooker. 

Adding ingredients then leaving it to do it's magic for a few hours with no help from me is a wonderful thing.

Today I'm sharing one of our favourite soups, which I usually make in a pot, but decided to make in the slow cooker this time.

It was just as delicious and super simple.

I'll be making it this way again.

Slow Cooker Carrot & Coriander Soup

I frequently throw everything in a soup. Lots of vegetables, beans or lentils and spices or fresh herbs. Sometimes it's good to have a simple, more pure flavour to let the main ingredient really shine.

This is one of those soups.

The BASE is onion, garlic and ginger.

The MAIN EVENT is fresh carrots.

The FLAVOURINGS are simple. Stock, salt, pepper and fresh coriander.

Nothing complicated, just a really tasty soup.

Slow Cooker Soup

A few things to remember when making slow cooker soup:

  1. LESS LIQUID - When making slow cooker soup you need less liquid. So less vegetable stock in this case. When converting a recipe that is usually cooked in a pot on the cooker top, the general rule is cut the liquid by a third.
  2. TIME SAVING - You save prep time as there is no need to saute the onion, garlic and ginger. Just throw it all in uncooked.
  3. FAT FREE - Because the base ingredients aren't cooked first, there's no need to add oil either which that cuts down on the fat and calories too.
  4. A SWIRL OF CREAM - Remember if you add a splosh of cream at the end, it will add fat and calories. 
  5. KEEP WARM SETTING - One of the great things about a slow cooker is that it's safe to leave unattended to cook and when the cooking time has ended it will keep your dish warm.

The star of the show in this soup is the carrots. Sweet, tasty carrots. A cheap addition to so many recipes. So versatile.

Carrots can be grated and added to salads, cut into sticks and served with a dip for a tasty snack. They are added to soups and stews are in the base for pies, bakes and pasta sauces. They are also tasty in smoothies and juices and added to cakes. 

As well as being wonderfully versatile, carrots are rich in antioxidants, vitamin B6, vitamin K dietary fibre, beta carotene and potassium.

Carrot recipes

whole onion


Onion is the base to most soups, in fact most savoury dishes. They are cheap, store well and are really good for you.

Onions are a good source of fibre, vitamin C and folic acid. They also contain iron, calcium and protein.

garlic cloves


We all know garlic adds lots of flavour to dishes, but did you know how healthy it is for you?

It's a good source of fibre, manganese, vitamin B6, vitamin C and selenium and also contains calcium, iron, potassium and copper.

fresh ginger root

Fresh Ginger

In soups like this, if you don't have fresh ginger you can use dried ground ginger. 

Both fresh and ground add a lot of flavour. In a soup with simple flavours like this one, I like the flavour of fresh ginger, but it's up to you.

It's another healthy ingredient. It contains fibre and protein as well as vitamin B3, B6 & C, iron, potassium, zinc and magnesium.

Making Slow Cooker Carrot & Coriander Soup

onions in slow cooker

Step 1 - Onions

Add chopped onions, garlic and fresh ginger to your slow cooker pan. There is no need to add any oil or pre-cook this mixture.

Step 2 - Carrots

Next add your chopped carrots. This recipe uses a lot of carrots, so get ready to chop (or get your food processor out!).

Step 3 - Seasoning

This soup is simply seasoned with salt and pepper. You don't need too much salt as the vegetable stock contains salt and you don't want it too salty. It can always be added at the table for individual tastes.

Step 4 - Stock

Add vegetable stock. The main thing to remember when adding stock to a slow cooker soup is use less than usual. The liquid with not cook down and evaporate like it does in a pot, so you need less liquid.

Step 5 - Slow cook

Slow cook on high for 4 hours or low for 6 hours. If you have a keep warm function, your slow cooker will keep a low heat under the soup until you are ready to serve it.

Blended carrot soup in slow cooker

Step 6 - Blend

Blend the soup with a stick blender. It will thicken the soup up. 

However if like me you like some texture in a soup, don't blend until completely smooth.

Step 7 - Fresh herbs

Finally add fresh coriander. Add it after blending. 

If you add while it cooks you will lose the lovely fresh flavour of the coriander and if you blend it when you have added the coriander you will end up with a sludgy colour and not the beautiful orange you see above.

  1. Oooh, I JUST got a recipe to try that is a deeply creamy carrot soup with soaked cashews, coriander, and ginger in it -- I wonder if I could just chuck them into a slow cooker soup after they were soaked and stick blend it for added creaminess?? Now I have to experiment!

    1. Oh yes definitely, just remember less stock. Although I never understand the urge to soak cashews when you can buy perfectly good soya cream. It's not like you need to add a lot to the soup.

  2. Can I ask why you put the coriander in at the end? Jill

    1. You get the best flavour from fresh herbs if you add them at the end. You get the fragrance from them, which can be a bit lost if added earlier. Whereas dried herbs are better added during cooking.

      Oh and if you add the coriander before blending the colour of the soup goes a bit sludgy and you lose that beautiful orange colour.

  3. Looks wonderful, just what I need to warm me up!

  4. I've been hunting for new soup recipes and this one looks delicious! Putting it on my menu for next week :)

    1. Excellent, what good timing Julia. I hope you enjoy it.

  5. Perfect soup for the season. So delicious and great combo!

  6. Great recipe! I love making soups in my slow cooker.

  7. I've been hankering after getting a slow cooker for ages, and recipes like this are definitely helping push me in the direction of buying one! That soup looks just perfect for a cold autumn evening.

  8. Could you let me know how much fresh ginger you need - I can’t see a quantity in the recipe. Thanks!

    1. Whoops! Well spotted! I'll have to correct that today I usually peel and finely chop a piece about 1 inch/2 1/2 cm long or a couple of taps of ground ginger.

    2. That should read teaspoons not tsps, darn auto-correct.

    3. Thank you - looking forward to trying it out.

  9. Thank you! Looking forward to trying it.

  10. Still not correct in ingredients for ginger amount but having scrolled down, I've seen the response to someone thank you. Looking forward to trying this one!

    1. Thanks I thought I'd sorted it, obviously didn't hit save. I've sorted it now.

  11. Lovely recipe! Perfect soup and such good flavours. I’ll be making this every week or so now, so easy and delicious!

    1. I am so glad you enjoyed it. It's my son's favourite soup.

  12. I need to make this as I have so many carrots that need using but I will be freezing it once made and using over the coming weeks. Should I still put the coriander in before I freeze it or add it as and when I defrost a portion?

    1. You cam add the vorinader before you freeze if you like. Enjoy it. It's a firm favourite here.
