I love pumpkin soup. It was one of the first things that I learned to cook, and I can remember feeling sooo fancy when I topped it with a dollop of sour cream and some crispy bacon pieces!

Here in Tasmania, winter is the perfect time to hunker down with a warming and hearty bowl of goodness and this flavour-packed sneaky twist to your higher carb pumpkin soup will leave you wanting for nothing…except maybe for summer to hurry up.
Enjoy!

Ingredients (makes 8 servings)

  • 1/4 medium pumpkin such as Delicata or Hokkaido, seeds removed (750 g/ 1.65 lb)
  • 1 medium cauliflower (750 g/ 1.65 lb)
  • 1 red onion, cut into wedges (60 g/ 2.1 oz)
  • 1 clove garlic, sliced
  • 4 tbsp extra virgin olive oil (60 ml/ 2 fl oz)
  • 4 cups chicken broth or vegetable stock (about 1 L)
  • Optional: full-fat yoghurt, sour cream or heavy whipping cream, and/or crispy bacon to serve

Instructions

  1. Pre heat oven to 180 °C/ 355 °F (fan assisted), or 200 °C/ 400 °F (conventional) .

  2. Pell pumpkin and cut into chunks (if you are using Hokkaido you won't need to peel it). Peel onion and cut into wedges. Peel garlic and slice roughly. Tumble all ingredients on a lined baking tray and then drizzle with about half of the olive oil. Bake for 45 minutes.

  3. While the pumpkin mixture is roasting, cut the cauliflower into florets and boil until just fork soft.
  4. Drain the cauliflower and sit aside until the 45 minute mark of the pumpkin.
    Note: Another option is be to roast the cauliflower in the oven just like the pumpkin. If you do that, it's best to bake the cauliflower in another tray, or in a large enough tray so that all the ingredients are in a single layer (you don't want the pumpkin boiled).

  5. Remove the pumpkin from the oven and create a space in the centre of the tray. Add the cauliflower and drizzle with the remainder of the olive oil. Place tray back in the oven for approx. 30 minutes.

  6. Once done, place roasted vegetables into a saucepan with your chicken broth and bring to the boil.
  7. Remove from heat and blitz with an immersion blender or stand blender. Test and then season to taste.

Made this pumpkin soup with some slices leftover Pig wings from the bbq. Tasted great.  The amount is good for the rest off the week 😁

Thank you Marjolijn, glad you enjoyed!

Made this last night with roasted Hokkaido! I served it two ways: last night as-is with smoked salmon and creme fraiche and at lunch with a touch of stevia power and creme fraiche. Both were very tasty but I think the touch of stevia made it closer to what I expected of pumpkin soup. Will make again!

Thank you for this recipe, it is very good and conforting for winter  I always end up will less servings in the end. In this recipe you only add 1l of chicken stock. Do you add any water at all?

Hi Catia, it is quite possible that I miscalculated the amount "per serving" which is only estimated. I will change it to 1 1/4 cups which will hopefully be more accurate. Thank you for letting me know!

Thank-you for the recipe! Can you substitute canned pumpkin?

Reply

Absolutely! You can use canned pumpkin or pumpkin puree (in this case no roasting of pumpkin, only roast the onion and optionally also the cauliflower). I hope this helps!
