How to make slow cooker Thai pumpkin and red lentil soup

  1. Cook the first 6 ingredients (all the vegetables and spices) for a few minutes on the stove top to begin releasing the lovely flavours. If you have a multi-cooker or a slow cooker with a saute function, this gets really easy!
  2. Add the lentils, coconut milk and stock/broth. Then switch on your slow cooker and walk away for 6 to 8 hours (or longer!).
  3. Blend with a stick blender or in a food processor in batches.
  4. Season well and scatter over fresh coriander.

How to serve this Thai pumpkin and lentil soup

As you can see, I keep my Thai pumpkin soup simple. I sprinkle it with a little fresh coriander, toast some bread and drizzle it with olive oil and sprinkle it with salt, and I’m done.

If you want to be a bit fancier, however, you can:

  • Sprinkle your soup with some toasted pumpkin seeds.
  • Make some of these LIFE-CHANGING crispy halloumi bites and sprinkle them over the top (DELICIOUS!).
  • Make some kale chips and sprinkle them over the top! (Got an air fryer? They’re really easy to make!)
  • If you aren’t a vegetarian, fry some bacon bits and sprinkle them over the top. Mmm!
  • Dot the top with some fresh pesto
  • And… my favourite… make some of these amazing pesto cheese twists for dunking!

How do you freeze the soup?

This pumpkin soup will keep for 3 to 4 days in the fridge, but it’s also perfect for freezing.

This recipe makes about 6 servings – pretty good! But if you have a big enough slow cooker why not make double so that you can freeze more for later? Suddenly Winter doesn’t seem so bad!

There is no magic freezing formula. Simply cool in freezer safe containers, put on a lid and freeze for up to 3 months. Make sure you do wait until the soup has cooled as you don’t want to risk raising the temperature of your freezer even a little.

I usually freeze soup and other meals in glass containers because I feel they’re the safest. Just don’t overfill the containers. Leave at least an inch at the top. Remember the soup will expand as it freezes and you don’t want the container to break.

Freezer safe Ziploc bags work well too. Just remember to label your bags or containers with the contents and date! Ever stood there for 10 minutes trying to peer through frosted glass to work out what something is? Not fun!

Top 5 slow cooker tips

1 Flour-coat & brown:

You can absolutely just dump your meat and veggies in the pot and run. Your meal will still end up delicious, but taking just an extra few moments to brown your meat and/or vegetables on the stove top first will really help to seal all the juices into the meat and boost the flavour of the final dish.

For casseroles and stews, you can also be extra clever by rolling your meat in a little flour first. This will ensure that you end up with a richer, thicker sauce.

2 Get organised

If you’re not keen on the idea of going to work smelling of onions and garlic, then prepare everything the night before (including browning the meat).

Throw it into the pot with your liquid covering the veg and meat and then put it into the fridge.

In the morning just pop the pot back into the slow cooker base and turn it on. Just try to remember to take it out of the fridge when you get up so that it warms up a little before you switch it on and you don’t risk cracking your pot due to extremes of temperature.

3 Don’t be a peeping Tom

I know, I know, it’s so tempting to keep having quick peeks at your delicious feast cooking up there all by itself, especially when the gorgeous smells start to permeate the room.

But … well, DON’T.

Especially in the first couple of hours of cooking.

Each time you lift the lid, you’ll lose around 15 to 20 minutes of cooking time because that’s how long your crock pot will take to regain the lost heat.

Some people would disagree here, but you don’t really need to stir, either, unless your recipe specifically tells you to do so. The whole point of a slow cooker, remember, is to ‘dump and go’!

4 Get fresh at the end

To cut through the richness of many slow-cooked dishes and/or add colour and vibrance to the flavours, do one or more of these things just before serving. Generously add:

fresh herbs, lemon zest, grated parmesan, high quality olive oil or even yoghurt, crème fraiche or cream (dairy may curdle if added at the beginning of cooking)

Your dish would have been wonderful just as it was, but such an added touch could make all the difference and turn a really good meal into an absolutely scrumptious one!

5 Be a greedy guts

Well, sort of. If your crock pot’s big enough (and you don’t have five kids to guzzle all the food down on one night), try to make double so that you can freeze some. You might as well leave yourself with no work at all for another day!

Now of course these are just my top 5 tips – there are loads more (if you’ve got any to share, I’d love it if you could mention it in the comments below!)

Above all remember that crock pots aren’t just for casseroles and stews. You can make cakes & puddings, chili and bolognese sauces, ribs, curries, pot roasts, soups, stocks and quite possibly hundreds of other things in there, too.

Thai pumpkin & red lentil soup

A deliciously thick, spicy, creamy, warming & healthy crock pot soup – perfect for a wholesome Autumn or Winter lunch.
Prep: 10 minutes
Cook: 8 hours
Total: 8 hours 10 minutes
Servings: 6


  • 1 onion, chopped
  • 1 small to medium pumpkin, peeled and chopped into smallish cubes
  • 2 garlic cloves, crushed
  • 2 cm piece fresh ginger, finely sliced or grated
  • 2 tablespoons Thai red curry paste
  • 2 tablespoons tomato puree
  • 1 cup dried red split lentils
  • 1 can coconut milk, not light
  • 2 cups chicken or veggie stock, good quality
  • salt and pepper to taste
  • fresh coriander, to sprinkle over at the end


  • In a little oil, cook the onion with the pumpkin for a few minutes on a medium heat on your stove top, then add the garlic, ginger, curry paste and tomato puree. Cook for another minute or so, then transfer to your crock pot.
  • Add the lentils, coconut milk and stock and cook on low for 6-8 hours (longer if you like – or 4 hours on high if you’re short on time).
  • Blend until smooth with a stick blender, then stir in salt and pepper to taste. Serve and scatter with the fresh coriander.


A note about the coconut milk

Your coconut milk may (but may not) look as if it’s split when it’s finished cooking (mine did). Don’t worry about this at all. As soon as I blended the soup, all was fine!

Thick or thin?

This makes quite a thick soup. The first portion I ate I ate it super thick and really enjoyed it, but the next day I added a little water to thin it out a little. Both ways were nice, so the choice is yours!

Refrigerating and freezing the soup

This pumpkin soup will keep for 3 or 4 days in the fridge.
If you’d like to freeze it, let it cool thoroughly first (pour into a container with a lid and immerse in a cold water bath if you want to cool it faster). 
Then pour into freezer safe containers or Ziploc freezer bags. Don’t fill glass containers too much. Leave at least an inch at the top of the container to allow for expansion as the soup freezes. 
Freeze for up to 3 months!

  1. Also … I have three crockpots of various sizes.
    What size pot is this recipe for?

    Thanks again, in advance.

    1. Hi Lark!
      Really happy you want to give this a go – it’s a delicious soup!
      My crock pot is small to medium (4.7 litre) but I don’t think the size of your crock-pot will affect the recipe too much. Also, don’t worry about the exact amount of pumpkin – I just used a smallish one and chopped it into smallish cubes so that they’re easy to blend at the end. Hope that’s enough info – I tend to me a bit of an ‘imprecise’ cook, but I think you can vary the amounts slightly in this recipe no problem
      Let me know how it goes!! 🙂
