This easy 5 ingredient roast pumpkin soup takes just 10 minutes to prepare. Chop, drizzle, then let the oven do most of the work before you puree it to a silky smooth soup and dive in with a spoon!
Why we love this recipe
- When pumpkins are in season they can be cheap to buy, making this a very budget friendly soup. In Australia right now I bought a large pumpkin for $5, which is more than enough to make 4 times the amount of this soup!
- It costs less than $0.70 a serve if you are in Australia, and less than 40p a serve if you are in the UK.
- Talking of scaling up, this soup can easily be halved if there are one or two people in your household, or multiplied up to feed a crowd.
- This pumpkin soup is made without cream and from simple store cupboard ingredients.
- Roasting the pumpkin brings out its sweetness as well as removing some of the liquid from the pumpkin, resulting in a smooth, silky soup without the need for any dairy.
- It is a 5 ingredient soup recipe.
- You can make the soup ahead and it freezes well, making it an ideal budget recipe for batch cooking together with this carrot lentil soup and pumpkin peanut butter soup.
- Not only is this a healthy soup, but it is gluten free, vegetarian, vegan, and nut free.
Ingredients notes and substitutions
- Pumpkin – my personal favourite pumpkin variety to make this soup with is the Jap or Kent pumpkin with speckled green skin and orange flesh, and the soup in the video and photos is Kent pumpkin soup. You can make this pumpkin soup recipe with Jarrahdale pumpkin, Queensland blue pumpkin, butternut squash or other pumpkins. The different varieties can take slightly different times to roast so just keep an eye on them in the oven.
- Onion – brown onion.
- Garlic – roasting the garlic in the skins with the pumpkin brings out the sweetness without it being a harsh garlic flavour. If you don’t have fresh garlic, use ½ teaspoon garlic powder.
- Stock – vegetable stock, or if you are not making this soup for vegetarians feel free to use chicken stock. If you don’t have stock, dissolve a stock cube in 750ml / 3 cups of water. In the video I have used my homemade vegetable stock.
How to make this soup recipe
For video showing how to make pumpkin soup please see recipe card at the end of the post.
- Cut and peel the pumpkin.
- Chop and peel the onion, and break into layers (not single layers as these can easily catch and burn), and place on a lined baking tray with the garlic cloves.
- Drizzle with oil, salt and pepper and place in preheated oven to bake.
- Stir halfway through cooking.
- When soft, remove from the oven and tip into a medium to large saucepan.
- Squeeze the garlic from the garlic cloves.
- Add the stock or water and using a hand blender, blend until smooth.
- Heat gently, check for salt and pepper and serve.
Yes you can use butternut squash to make soup, preparing and roasting as per the recipe. The skin of butternut squash is thinner than pumpkin and becomes soft and edible when cooked so if you want, you can leave it on. Leaving the skin on may not produce such a silky soup.
No. you don’t need to peel pumpkin before roasting. However pumpkin skin is quite thick so once cool enough to handle, remove the skin before blending into the soup. Removing the pumpkin skin after cooking can often be easier than trying to chop it off the raw pumpkin.
Cumin, coriander, chilli, ginger, garlic are all spices that go well with pumpkin and make a delicious flavour packed pumpkin soup.
My recipe tips
- Times for roasting the pumpkin will very slightly depending on the variety and ripeness of your pumpkin. Ripe pumpkins will be soft sooner than those that aren’t ripe, so it is good to check before you take the pumpkin out of the oven.
- Don’t worry if the pumpkin and onion are slightly blackened on the edges. This adds a lovely sweet caramelisation to the soup. Just make sure there’s not too much of this – like most of the pieces are black – as this will make the soup taste bitter. If a lot has caught, chop these bits off the vegetables before blending.
- Tip for a smooth soup: make sure that the pumpkin is soft and well-cooked. If in any doubt then put back in the oven for another 5 minutes and test again. Well-cooked pumpkin makes a lovely smooth puree. If it’s not soft, then your pumpkin soup could be a little grainy. It sill tastes good, but it’s not as silky.
- Top the pumpkin soup with homemade croutons, roasted pumpkin seeds / pepitas, or sprinkle feta cheese over the pumpkin soup (I love the combination of feta and pumpkin!).
- Serve with cheese scones, sausage rolls or cheese and onion rolls.
- Store in a covered container for up to 3 days in the fridge.
- Freeze – cool the soup completely then freeze for up to 4 months. I personally find it easier to freeze in individual portions, or sometimes portions for 2 people, then I can grab this for lunch or dinner and defrost in the fridge overnight.
Ideas for leftover soup
If you end up with a little leftover soup that is not quite large enough to be a serving, you can:
- stir it into a soup such a minestrone for a creamy base.
- stir a spoonful or two through stews.
- add to cooked pasta and sprinkle with grated cheese or a spoonful of ricotta for a quick and easy dinner.
- Spicy pumpkin soup – add a teaspoon of mild curry powder or sprinkle over some dried red chillies.
- Other flavourings – a teaspoon of ground cumin and ground coriander would add a lovely flavour to the soup.
- Coconut milk – if you want a creamy coconut pumpkin soup then replace 250ml (1 cup) of the stock or water with coconut milk. (This recipe is also a useful one to make if you have a little bit of leftover coconut milk that needs using up!)
