    Easy pumpkin soup recipe with leek, made in only 35 minutes - and even quicker with canned pumpkin. For real French flavour, make this healthy pumpkin soup and chestnuts - blend in some cooked sweet chestnuts which naturally thickens it.

    Is Pumpkin Soup Healthy?

    This fresh pumpkin soup recipe is particularly healthy. For a bowl, it counts just 155 calories a serving.

    Not only is it not fattening, but it's full of iron, zinc, fibre and carotene (see more on the market pumpkin page). Carotene is what we all need at this time of year to bring the glow back to our cheeks.

    Alternatively, if you're not following a particular calorie-counted or vegan diet, swirl in some cream just before serving. What's more, the added leeks are so good for you: they're anti-inflammatory and they help to clean the gut (popular word just now, isn't it?)

    For more, see the market guide to leeks (poireaux)

    What Part of Pumpkin is Used for Soup?

    I normally use regular pumpkin (bought in slices) from the market for this soup. Use the flesh only of regular pumpkin without the skin.

    If you like a more intense pumpkin flavour, it's also great with red kuri squash, known as potimarron (Japanese chestnut pumpkin) in France. I love it so much, I even made spiced pumpkin macarons with it! The beauty of using Japanese chestnut pumpkin is that the skin is edible.

    Roasted Pumpkin Soup

    As it's difficult to cut through the pumpkin raw, roast the whole pumpkin in the oven for 20 minutes first. This makes it easier to cut into chunks. It perhaps takes a bit longer to prepare but that way, you can call it roasted pumpkin soup! Don't have fresh pumpkin at hand? Then use tinned following the same recipe.

    Ginger in Soup

    Although optional in this recipe, ginger is fabulous added to pumpkin soup. It gives a great spicy kick to bring us back on top form and it's particularly good for digestion. Moreover, ginger helps keep colds at bay and is good for virility. Oh-là là ! 

    I use a good tablespoon of grated root ginger. However, ground ginger can also be used if you can't find it easily.

    Incidentally, if you love ginger, add it to this chocolate fondant cake, chocolate beetroot cake, rhubarb compote and to passion fruit and chocolate cake.

    Pumpkin Soup and Chestnuts

    For a naturally creamy touch without adding any cream, toss in a few pre-cooked chestnuts in with the stock. The result is extra thick and the flavours just combine so well together. Keep a few aside to crumble on chestnuts for the garnish with some crunchy pepitas or pumpkin seeds.

    How to Serve Soup Holiday Style

    For a festive pumpkin soup look, add some fresh herbs (parsley, coriander or sage leaves) to look like holly and add a couple of fresh cranberries or pink peppercorns.

    Although ATTENTION! Pink Peppercorns should be strictly avoided if you suffer from nut allergies. Read about it more from my friend, Christina Conte, who says to avoid pink peppercorns if allergic to nuts.

    Take Pumpkin Soup to the Next Level: Garnish with Macarons

    What? Macarons with soup? Intrigued faces are guaranteed at the table! I love taking guests by surprise with savoury macarons as a mini pre-starter or Amuse-bouche. Here I served it with a couple of mini curry tikka mac'sala macarons (from my first book.) The flavours together are a delicious adventure.

    See more in my article on what to serve with savoury macarons.

    Ingredients
     

    • 2 tablespoon olive oil
    • 4 medium leeks sliced
    • 900 g (2lb or 2 15oz tins of purée) pumpkin peeled & chopped* (or one small potimarron chestnut pumpkin)
    • 1 tablespoon fresh ginger root grated (or 1 teaspoon ground ginger) OPTIONAL
    • 850 ml (1.5 pints/ 3 cups) vegetable stock (or chicken broth)
    • good pinch freshly grated nutmeg
    • salt & pepper to taste
    • 30 g (2 tbsp) cooked sweet chestnuts to garnish

    Instructions
     

    • Heat the olive oil in a large pot then soften the leeks and pumpkin together. Sweat gently for about 5 minutes then add the ginger, if using. Sweat a couple of minutes more.
    • Add the stock (just enough to cover the vegetables), cover and simmer for about 25 minutes.
    • Blend with a hand mixer, add the nutmeg and season with salt and a few grinds of the pepper-mill to taste.

    Notes

    Pumpkin: if using Japanese chestnut pumpkin or red kuri squash (potimarron), roast whole in the oven for about 20 minutes to make it easier to cut into chunks. No need to discard the skin as this variety of squash is edible. Otherwise this recipe works well using canned pumpkin (2x15oz tins of purée).
    Pumpkin and Chestnut Soup: If you prefer without ginger, add some cooked sweet chestnuts to further thicken the soup and/or garnish with a few crumbled on top. This delicious flavour combination is typical for Autumn or fall in France.
    To Serve: top with finely chopped fresh herbs (parsley, coriander or fried sage leaves). For a festive touch, add a couple of fresh cranberries or pink peppercorns (N.B. pink peppercorns are to be avoided if you have a nut allergy).
