Introduction

This is the kind of recipe I love because you do the main work once and create two completely different soups.

We begin with one simple roasted pumpkin soup base. Half is finished as a classic creamy pumpkin soup, while the other half is transformed with coconut cream, sweet soy, fish sauce and coriander into a fragrant Asian-style version.

Roasting the pumpkin first develops its natural sweetness and gives the soup a much deeper flavour than simply boiling everything together. We are also leaving the skin on the pumpkin. Once it is cooked and puréed, you will not notice it, but you will be adding more fibre and reducing unnecessary preparation and waste.

Butternut pumpkin is my first choice for soup because of its naturally sweet, rich flavour and smooth texture. Kent, Jap or Queensland Blue pumpkin will also work beautifully when they are available.

It is one soup, finished two ways - a great Kitchen 101 technique that shows how a few carefully chosen ingredients can completely change the personality of a dish.

Method

Prepare and Roast the Pumpkin
  1. Wash the pumpkin well, as we are leaving the skin on.
  2. Cut the pumpkin into large, evenly sized chunks and remove the seeds.
  3. Place the pumpkin pieces into a large mixing bowl.
  4. Add the cinnamon, nutmeg, honey and olive oil.
  5. Toss thoroughly until the pumpkin is evenly coated.
  6. Place the pumpkin into the cooking pot of the Ninja 11-in-1.
  7. Select the Bake/Roast function and cook at 185°C for approximately 30 minutes, or until the pumpkin begins to soften and caramelise around the edges.
Pressure Cook and Purée
  1. Once the pumpkin has roasted, pour in the chicken stock.
  2. Fit the pressure-cooking lid and cook on high pressure for 15 minutes.
  3. Allow the pressure to release safely according to the appliance instructions.
  4. Using a stick blender, carefully purée the pumpkin and stock until completely smooth.
  5. Alternatively, transfer the soup in batches to a blender. Do not overfill the blender when working with hot liquids.
  6. For an exceptionally smooth finish, the soup can also be passed through a fine sieve.
  7. Taste the puréed soup and only now add Olsson’s Sea Salt and Spice Lab Mélange of Peppercorns as required.
  8. Divide the soup into two equal portions.
Finish One: Classic Creamy Pumpkin Soup
  1. Add 150 ml cream to one half of the soup.
  2. Stir well over gentle heat until the cream has been incorporated and the soup is hot.
  3. Taste and adjust the salt and pepper if required.
Finish Two: Asian-Style Pumpkin Soup
  1. Add 150 ml coconut cream to the second half of the soup.
  2. Add the sweet soy sauce, fish sauce and chopped coriander.
  3. Stir over gentle heat until everything is combined and the soup is hot.
  4. Taste before adding any additional seasoning. The sweet soy and fish sauce should provide enough seasoning without the need for extra salt.

Alternative Method(s)

  • Butternut pumpkin gives the best flavour and texture for soup, although Kent, Jap and Queensland Blue pumpkin can also be used.
  • Leave the pumpkin skin on. It adds fibre, saves preparation time and reduces waste.
  • Cut the pumpkin into similar-sized pieces so everything cooks evenly.
  • Do not add the salt and pepper until the soup has been cooked and puréed.
  • Roast the pumpkin until it develops some colour. That caramelisation is where much of the flavour comes from.
  • When adding the sweet soy and fish sauce to the Asian-style soup, taste before adding any extra seasoning.
  • If using a jug blender, never fill it to the top with hot soup. Blend in smaller batches and allow steam to escape safely.
  • Garnishes are not simply decoration. Toasted nuts, seeds, fried shallots and coconut provide texture and make a smooth soup more interesting to eat.
  • This recipe demonstrates a very useful cooking principle: make one reliable base and change the finish to create completely different meals.
  • Skill Focus

    Roasting to Build Flavour

    Roasting caramelises the pumpkin’s natural sugars and gives the soup a richer, more rounded flavour. This is why roasting before adding the stock produces a better result than simply boiling raw pumpkin.

    Leaving the Skin On

    Pumpkin skin softens during roasting and pressure cooking. Once blended thoroughly, it adds body and fibre without affecting the finished texture.

    Seasoning at the Right Time

    Do not season the soup before roasting or pressure cooking. The stock will reduce slightly and the flavours will concentrate as the soup cooks.

    Purée the soup first, then taste and season. This gives you much greater control over the final result.

    Safely Blending Hot Soup

    A stick blender is the simplest option because the soup can be blended directly in the cooking pot.

    When using a jug blender, work in small batches, leave room for steam to escape and never completely fill the jug with hot soup.

    One Base, Multiple Finishes

    Learning how to create a neutral base and then change its flavour is an important cooking skill. It saves time, reduces waste and gives you more variety without preparing two separate recipes.

    Chef Ian's Tips

    Oven and Stovetop Method
    1. Preheat the oven to 185°C.
    2. Prepare and season the pumpkin with the cinnamon, nutmeg, honey and olive oil.
    3. Spread the pumpkin over a lined baking tray and roast for approximately 30–40 minutes, or until tender and lightly caramelised.
    4. Transfer the roasted pumpkin to a large saucepan.
    5. Add the chicken stock and bring to a gentle boil.
    6. Reduce the heat and cook at a light simmer for approximately 30 minutes, or until the pumpkin and skin are completely soft.
    7. Purée the soup using a stick blender, jug blender or fine sieve.
    8. Season the soup after it has been puréed, then divide it into two portions and finish each soup as directed above.

    Allow approximately two hours for the complete oven and stovetop method, including preparation, roasting, simmering, blending and finishing.

    Plating and Serving

    Classic Creamy Pumpkin Soup

    Ladle the soup into warm bowls. Finish with a small swirl of cream and a very light dusting of sieved cinnamon.

    Add chopped parsley and your choice of toasted pine nuts, pepitas or flaked almonds for colour and texture.

    For a slightly sharper finish, drizzle a small amount of balsamic glaze over the soup just before serving. Do not use too much — it should balance the sweetness of the pumpkin rather than overpower it.

    Serve with warm crusty bread, toasted sourdough or simple garlic bread.

    Asian-Style Pumpkin Soup

    Ladle the soup into warm bowls and garnish with chopped coriander, fried shallots and toasted coconut.

    The fried shallots provide crunch, while the coconut reinforces the flavour of the coconut cream.

    Serve with warm flatbread, roti or crisp wonton strips. It can also be served in smaller bowls as the beginning of an Asian-inspired meal.

    Make-ahead Option(s)

    The pumpkin soup base can be made up to three days ahead and stored in an airtight container in the refrigerator.

    For maximum flexibility, prepare, purée and divide the base soup, but wait to add the cream, coconut cream and final flavourings until you are reheating it.

    Reheat gently on the stovetop, stirring regularly. Avoid boiling the soup once the cream or coconut cream has been added, as this can affect its smooth texture.

    The soup can also be frozen before adding the cream or coconut cream. Freeze in labelled portions for up to three months, thaw in the refrigerator and finish in your chosen style after reheating.

    Always add the fresh garnishes immediately before serving.

    Variations

    Vegetarian or Plant-Based

    Replace the chicken stock with vegetable stock or water.

    For a completely plant-based version, replace the honey with maple syrup and use coconut cream or a plant-based cooking cream.

    Omit the fish sauce from the Asian-style soup or replace it with a vegetarian fish sauce or a little additional soy sauce.

    Add a Little Heat

    Add a small amount of chilli oil, fresh chilli, sambal or curry paste to the Asian-style soup.

    Begin with a small quantity. You can always add more, but you cannot take it back out.

    Curried Pumpkin Soup

    Add a teaspoon of mild curry powder when coating the pumpkin before roasting. Finish with cream or coconut cream.

    Ginger and Coconut

    Add a teaspoon of finely grated fresh ginger to the Asian-style finish for extra fragrance.

    Extra Roasted Flavour

    Roast one brown onion or several garlic cloves alongside the pumpkin, then purée them into the soup.

    Different Pumpkin Varieties

    Kent, Jap and Queensland Blue pumpkin can all be used. The final soup may vary slightly in sweetness, thickness and colour depending on the pumpkin selected.

    FAQs

    Do I really leave the pumpkin skin on?

    Yes. Wash the pumpkin well, remove any damaged areas and leave the skin on. It becomes soft during cooking and blends into the soup, adding fibre and reducing preparation time.

    Which pumpkin is best for soup?

    Butternut pumpkin is my first choice because it has a naturally sweet flavour and produces a smooth, creamy soup. Kent, Jap and Queensland Blue pumpkin are also suitable.

    Why do I season the soup after blending?

    Chicken stock, sweet soy and fish sauce all contain seasoning. Waiting until the soup has been cooked and puréed prevents it from becoming too salty.

    Can I make only one flavour?

    Certainly. Leave the soup as one batch and double the finishing ingredients for your chosen version.

    For the classic soup, use approximately 300 ml cream. For the Asian-style version, use approximately 300 ml coconut cream and adjust the soy sauce and fish sauce gradually to taste.

    What can I use instead of cream?

    Use coconut cream, plant-based cooking cream, evaporated milk or a lighter cooking cream. Each will produce a slightly different flavour and consistency.

    Can I freeze pumpkin soup?

    Yes. For the best result, freeze the puréed pumpkin base before adding cream or coconut cream. Add the finishing ingredients after thawing and reheating.

    What should I do if the soup is too thick?

    Add a little extra stock, water, cream or coconut cream until the soup reaches your preferred consistency.

    What should I do if the soup is too thin?

    Simmer it gently without a lid until some of the liquid evaporates. Stir regularly to prevent it from catching on the bottom.

    Can I use a blender instead of a stick blender?

    Yes. Allow the soup to cool slightly and blend it in small batches. Take care when blending hot liquids, as steam can build up inside the jug.

    Is the Asian-style soup very salty?

    It should not be. Add the sweet soy and fish sauce, mix well and taste before adding anything else. These ingredients normally provide all the seasoning the soup requires.
