Soup season is here and I for one am going all in.
Whether it's a cozy bowl of Vegan Chickpea Noodle Soup, some spicy Pumpkin Curry Soup, or Instant Pot Carrot Soup, I am here for it. If you, like me, want to go all in on soup feel free to peruse our Soups and Stews archives to get in on the goodness.
This particular soup recipe, Miso Roasted Butternut Squash Soup, is a seasonal favourite that I think you're going to want to get in rotation. It's velvety smooth, and has a deep, rich, complex flavour thanks to roasting the butternut squash before we blend it into the soup.
If you're wondering what the heck miso paste, coconut milk, and lime are doing in this soup together with warming spices like turmeric and smoked paprika, let me tell you, your taste buds are in for a treat.
I first published this recipe back in 2014, and like many of my older recipes, when I went back to freshen it up I gave my head a shake at all of the unnecessary steps. I previously instructed you spend your valuable time peeling and dicing the butternut squash before roasting, but 2020 Katie doesn't have time for that kind of nonsense.
Why would we peel and cube when we could simply hack that squash in half, scoop out the seeds, and throw it into the oven to roast while we take care of other things?
So let's get into it and make this new and improved roasted butternut squash soup.
What do I need to make this soup?
Time to gather your ingredients, my friends! Here's what you need:
- Butternut squash --> We're going with a nice big guy, around two pounds.
- Onion --> The usual wing man.
- Ginger --> For a bit of zing.
- Garlic --> Goes without saying.
- White miso paste --> You're going to love this flavour.
- Coconut milk --> One can of either lite or full-fat.
- Turmeric --> Bright yellow healing power!
- Smoked paprika --> The queen of spices.
- Chili flakes --> For some optional heat.
- Lime --> To balance things out.
- Coconut oil --> Builds great flavour into this soup.
I like to make my soups in a big, deep, heavy-bottomed pot. My favourite is this Dutch Oven from Le Creuset.
You will also need something to blend the soup with. I used my Vitamix for this recipe because I love how velvety smooth it gets this soup, but you can certainly also use an immersion blender and blend it right in the pot.
How do you make this recipe?
While admittedly this roasted butternut squash soup dirties up more dishes than I normally like, it's very simple to make. Are you ready for this? I'll talk you through it!
Step 1: Slice your squash in half and scoop out the seeds. Rub it with a bit of olive oil and season with salt and pepper.
Place it into a baking dish cut side up / skin side down, and place into the oven to roast for about 30 minutes, or until deeply golden and tender.
Step 2: While the squash is roasting, let's get the soup base ready.
Start by melting a bit of coconut oil in a heavy bottomed pot, and sautéing the onions until translucent. Add the ginger and garlic and sauté for a few minutes more.
Step 3: (above) Add the cilantro and spices and sauté for a couple of minutes more.
Step 4: When your flavour base is nice and cooked down (see below) you're going to add just a bit of vegetable broth to the pan.
We're using this to help lift any spices that are stuck to the bottom off the pot - but don't worry if they don't all come up, we'll be adding everything back into this pot eventually.
Step 5: Transfer the broth and flavour base to your blender. Scoop your roasted squash out of the skin (make sure it's cool enough to handle!) and add to the blender.
Step 6: Blend until completely smooth, adding a bit of extra broth if necessary.
*Note - If you are using an immersion blender you can do this blending step right in the soup pot.
Step 7: Transfer the squash mixture back to the soup pot.
Tip! I like to add the remaining broth into the blender at this point and run it for a few seconds to help get all off the squash mixture out.
Step 8: Add the remaining broth, coconut milk, miso, and lime juice to the pot.
Stir to combine, and gently heat to serving temperature.
That's it! You're done!
Can I make this soup in advance?
You sure can! Either the whole thing, and just reheat when you're ready to serve, or you can roast the squash in advance and throw the whole thing together quickly.
Roasted butternut squash is a great addition to your weekly batch cooking (related: Batch Cooking For Beginners) and can be used in a recipe like this Spicy Squash and Lentil Salad or even to make a Hassleback Butternut Squash if you par-cook it.
Can I freeze soup?
You can and you should. I almost always freeze a few portions of soup, and they're perfect for easy weeknight dinners.
I tend too freeze my soup in empty yogurt containers or wide-mouth mason jars. Just remember to leave enough head space at the top off the container for the soup to expand as it freezes.
Frozen soup also makes a great packed lunch as it doesn't slosh around in your bag during your commute - just make sure you've got somewhere to re-heat it on the other end.
How can I use up that miso paste?
First of all, worry not - miso paste lasts for ages in your fridge. And it's a handy ingredient to have on hand.
I use it in the broth for these 10-Minute Vegetable Ramen Noodles, in these Miso Maple Roasted Brussels Sprouts, or in this simple Miso Veggie Soup in a Jar.
What's the deal with butternut squash?
Glad you asked!
Winter squash such as butternut and other yellow-fleshed squash are rich in carotenoids, a precursor to vitamin A, and are a good source of vitamin C.
The seeds, when consumed in moderation, are a great source of healthy oils including linoleic acid (polyunsaturated omega-6 fatty acid) and oleic acid (the same monounsaturated fatty acid found in olive oil).
Winter squash also contains a good dose of fibre, potassium, vitamin C, and manganese.

Miso Roasted Butternut Squash Soup
- 1 medium butternut squash about 1kg / 2lbs, halved and seeds removed
- 2 teaspoons olive oil
- salt and pepper
- 1 tablespoon coconut oil
- 1 large onion diced
- 4 cloves garlic minced
- 1 - 2 tablespoon freshly grated ginger
- ½ cup finely chopped cilantro leaves and stems
- 1 teaspoon ground turmeric
- 1 teaspoon smoked paprika
- ½ teaspoon red pepper flakes
- 3 cups vegetable broth
- 14 oz coconut milk light or full-fat
- 1 medium lime juiced
- 2 tablespoon white miso
- salt and pepper
- toasted sesame oil for garnish
- cilantro leaves for garnish
- Preheat your oven to 200°C / 400°F.
- Slice the squash in half and remove the seeds.
- Rub with the squash halves with a bit of olive oil and season with salt and pepper. Place cut-side up in a baking dish.
- Place in the oven and roast the squash for about 30 minutes, until the squash is tender and beginning to turn golden brown.
- While the squash is roasting , heat the coconut oil over medium heat in a large heavy-bottomed pot. I love my dutch oven for this.
- Add the onions, and sauté for 3-5 minutes, until translucent.
- Add the ginger and garlic, and sauté for about 3 minutes, stirring often so that it doesn't burn.
- Add cilantro, turmeric, smoked paprika, and red pepper flakes, and cook for 3 minutes more.
- Add about 1 cup of vegetable broth to the pan and stir the bottom to help pick up any spices that are stuck.
- Once the squash is roasted, remove from the oven and let it cool slightly.
- Scrape the contents of the pot including the broth and spices into your blender.
- Scoop the squash out of the skin and add to the blender with the soup base.
- Blend on high speed until the mixture is very smooth, adding more liquid if you need to in order to loosen the mixture up.
- Pour the squash mixer from the blender back into the soup pot. Rinse the blender out with the remaining broth, and add that into the pot as well.
- Add the the coconut milk and lime juice.
- Heat the soup to a gentle simmer, just below a boil.
- Put the miso paste into a small bowl, and add a few tablespoons of hot soup. Stir into a slurry, then add this back to the soup. It's really important that the soup doesn't boil after you've added the miso, so reduce the heat and watch it carefully.
- Taste the soup and season with sea salt and extra lime juice if you like.
- Serve hot, drizzled with a very small amount of toasted sesame oil and a few cilantro leaves.
- Nutrition values are an estimate only.
- You can roast the squash a few days in advance and keep it in the fridge for quick weekday soup making.
- Blending the entire soup in the pot with an immersion blender also works well and will leave you with fewer dishes, however, the soup won't be quite as velvety as with an upright blender.
- Leftovers can stored in the fridge for about 3 days, or be frozen in individual portions.

This is Katie's best recipe. So many layers of flavour. I make this soup every week and have a second serving its so delicious. Thank you Katie
Lovely refresh of a great soup! So perfect for autumn slurping. And such beautiful images and light.
What a fantastic soup. I am all about the finish, when it comes to soup, most I make are pureed, and the more velvety the better! This one has such a great layering of flavors...it's not your run-of-the-mill butternut squash soup, and vegan friendly! LOVE LOVE LOVE!
I'm glad you enjoyed this soup as much as I do!
Miso was a sublime idea. Thanks for posting this!
Sounds amazing! I will definitely make this next week. I need hot soup today!
This really is a lovely soup. The ginger, miso, coconut, and lime work really beautifully together. Let me know how it turns out for you!
Made this soup a couple of weeks ago - grand! Even better after a couple of days in the frig. I was a bit heavy-handed with the ginger & got hotter soup than I'd expected (no fault of the recipe!), but it mellowed out a bit over time. Adding a dollop or 2 of Greek yogourt on serving was a lovely cooling touch. Definitely have added this to my repertoire!!
I have found a lot of other recipes calling for coconut milk, so I bought a case! But as it turns out, I don't quite "get it" .. I love the idea of making the soup creamy, but is there another way? I'm sure not so turned on to this ingredient and don't know exactly why, other than it seems needless. I can't use a whole can in once recipe, and it has to be used within a couple of days & end up throwing the remaining away. Am considering returning to the store.
Hi Diane. The coconut milk is in there for flavour! It adds a subtle but lovely hint of coconut. If you're not into the taste you can leave it out, but I do encourage you to give it a try in this soup. And this recipe uses a whole can, so nothing leftover to go bad in your fridge! But if you've got leftovers from other recipes you can try adding it to smoothies, which is also delicious.
Katie this soup is delicious! I usually don't like the blandness and texture of squash soups but the complexity of the miso, lime and coconut make this a new staple in my autumn/winter repertoire.
It is a complex yet so simply delicious soup!
beautiful! though you could try a drizzle of truffle too - love it with pumpkin!
Delicious recipe and beautiful photography!
Thank you so much!
Mmmm, I cannot wait to try this! It sounds so comforting and I love the flavor combination. Definitely making it soon. 🙂
I also feel quite homesick around Thanksgiving but I make sure to celebrate every year with my "family" here in Portugal. I can't get them to celebrate Halloween (boooo) but they've definitely gotten on board for Thanksgiving. It's probably just because of all the delicious food, though. 😉
It's a really lovely combination of flavours! Yes, we have an expats 'family' dinner for Thanksgiving, but most of our friends are American while we're Canadian, so we don't get Thanksgiving in October like we're used to.
Lu @ Super Nummy Yo!
Omg I love that you married butternut squash with coconut miso and lime! So creative. Definitely making this 😛
It's such a great flavour combination, isn't it?
A worthwhile autumn project for sure. Love everything about this. Yes, bring on the woolly jumpers and thick tights! This is the culinary version 🙂
This soup is calling your name with all those flavours, Kellie!

Katie, I just read your "about" page and saw that you live in Stockholm. We lived in Umeå for three years before coming to New York. By the way, this soup looks absolutely amazing. I wouldn't have a problem with the clean-up since every time I step into the kitchen it looks like a bomb went off. But at least the food is good!
Oh wow, Umeå! And I complain about the darkness in Stockholm! Umeå is like a totally different world. I've also got kitchen-bomb syndrome happening here - especially on weekends like this when my husband is away and I power cook for the blog!
Christine | No Gojis No Glory
Yeah....3 hours of daylight in the dead of winter was really tough to get used to, but at least we could always look forward to summer and the 24 hour daylight. The people up there are amazing though....very nice and hospitable. You and your husband should spend some time up there if you haven't already.
The light is the toughest thing! We've been in Stockholm nearly 5 years and I still find 1pm sunsets so crazy, but knowing you're going to have a glorious sunlight filled summer does make it easier to deal with. We'll definitely try and spend some time up north - we've got a good friend from Luleå so hoping to get to go there soon!
Butternut squash soup is so creamy and delicious, and I really like the addition of miso here!
The miso is really good! It doesn't turn it into miso soup, but adds a really nice layer of flavour.
I've been loving your blog for a while now! Thank you for this soup project - heading out now for ingredients not already stocked. Time flies for me as well & I hope your October is a bit of an improvement over your sept.
(I can't seem to get out of 'caps' here - ?)
Thanks Susan! The caps thing is to do with the font, the comment doesn't actually show up in caps. I had asked my web developer to fix that because it was confusing people, and it's fixed on my end, so I'll have to look into why it still appears in caps for you. Thanks for the comment!
Kristine @ Kristine's Kitchen
Butternut squash soup is one of my favorites, and I love how you've added the coconut, miso and lime to make the flavor really pop! I'm ready for October and soup weather, although I agree time is going by too quickly!
Those flavours really come together to make something special. I hope you try it out!
Oh my, my boyfriend does the same thing whenever I make soup. Its always a bunch of cumin, what is that?
Yes, it's cumin in my house too! Or smoked paprika - which is actually in this soup, but still!
1) Thanks for stopping my the blog earlier today!
2) This soup looks amazing, I have *almost* all of the ingredients to make it tonight, so I may pop out to grab some coconut milk...
3) LOVE the idea behind your blog, I will be back for sure 🙂
Thanks Emma! Glad you like what I'm doing here 🙂 I hope you popped out for that can of coconut milk, it's totally worth it!
I love these flavors and the addition of miso! So unique and different from all the other butternut squash soups out there. You have tons of great information around healthy eating and I'm signing up to follow your blog. Can't wait to see what comes in the future!
Thanks Nicola! Glad you like it here 🙂
I'm so with you on all of that - glad to be into October, ready for fall and lots of soup! This one looks awesome. I love butternut squash and the spices in here sound amazing. Pinning this so I can make it on a chilly day. 🙂
This soup is perfect for a chilly day. There's just that right amount of spice and so many layers of flavour.
Rachel @ Bakerita
Wow - this soup sounds phenomenal! I absolutely love all the flavors you put in here, so unexpected but it all sounds amazing. Pinned!
Thanks Rachel! Yep, the flavours all work really well together. Such a great soup!
October is one of my favorite months also, but it is crazy how time is flying this year. Wasn't it just June?!
Want to slurp up this soup and lick my bowl clean! ALl those flavors sound so good together.
I know, right? I mean it was literally just June yesterday. Now it's practically Christmas! You def want to lick this bowl clean, it is ah-mazing!
