Let's dive into exactly how to make this butternut squash and sweet potato recipe.
Ingredients You'll Need
This butternut squash and sweet potato soup is minimum effort with maximum flavour, so you really don't need many ingredients. To make this soup, you'll need:
- Butternut squash: A medium-to-large sized butternut squash is ideal for this recipe.
- Sweet potato: Either try to find a large sweet potato (almost as large as your squash), or the equivalent in smaller ones.
- Onion: I would recommend a white onion for this recipe, cut into large chunks.
- Garlic
- Vegetable stock
- Plant-based cream: I use the ElmLea brand plant-based cream for this recipe, but coconut cream would also work.
- Spices: Fragrant tumeric, cumin, smoked paprika, and a small pinch of cinnamon make up the components of this recipe, topped with chilli flakes for an extra punch of heat.
What's the Best Way to Blend Soup?
I always use a simple stick blender when making soup at home - it's less messy and uses fewer containers! However, you could also use:
- A blender
- A soup maker

How To Make Butternut Squash and Sweet Potato Soup
Soup should be comforting and filling - but it definitely shouldn't be over complicated. One of the beauties of this recipe is how easy it is to whip up with minimal hands-on time.
It makes a great lunch on it's own or with some crusty bread, but can also be bulked up with a cheese toastie for dinner!
Storage
This soup is perfectly fine to store in an airtight container in the fridge for up to 5 days after you've made it. It is also perfect for freezing. If like me, you're an allotment owner and have an abundance of butternut squashes to harvest in the autumn, this is a fantastic recipe to batch cook, freeze, and enjoy months later.
Substitutions, Swaps, and Alternatives

FAQs
Can I use a soup maker for butternut squash and sweet potato soup?
Yes, this recipe would work fine in a soup maker - just take note that if you add the vegetables without roasting them first, your soup may have a slightly different taste.
Do I have to roast the vegetables to make this soup?
Roasting the butternut squash and sweet potato for this soup give it a really delicious flavour, and it's a step I'd highly recommend. You can make this soup without roasting the vegetables first, but it won't taste quite the same.
Can I freeze butternut squash and sweet potato soup?
Yes, butternut squash and sweet potato soup is perfect for freezing - freeze in tupperware containers or in ziplock bags with the air squashed out of them to take up less space!
Can I substitute white potato for sweet potato?
No, I wouldn't recommend swapping out the sweet potato for white potato in this recipe.
Is this butternut squash and sweet potato soup gluten-free?
Yes, this soup is naturally gluten-free! Pair it with some gluten-free bread and butter on the side and tuck in.
What cream should I use for this recipe?
I drizzle a little of the ElmLea plant-based cream into the soup and to top it off. If you're in the UK, I find this cream alongside the typically dairy creams in most supermarkets, but especially in Tescos. If you can't source plant-based cream, coconut cream (that thick part from a tin) will also work great.
What to do if I want a chunky soup?
If you want a chunky version of this soup, I'd recommend roasting the butternut squash and sweet potato peeled in chunks. Then, you can blend up about ⅔ with the onion, garlic, stock, and seasonings, and stir in the remainder. This could be a couple variation of the recipe with some cannellini beans thrown in, too.
