Butternut squash soup is a classic fall and winter soup recipe. But today we’re roasting the butternut squash, which gives so much more depth of flavor and makes the soup easier to prepare (as you don’t have to cut the butternut squash).
Butternut squash soup is one of the top 5 fall and winter soup recipes usually on anyone’s list. And it’s one of my personal favorites, along with vegetable soup, cabbage soup, chicken soup, lentil soup, and (this may come of bit of a surprise) taco soup. But we can’t forget that butternut squash soup is also the quintessential soup recipe for Thanksgiving.
Roasting veggies is one of my favorite preparation methods, as it imparts a sweet and smoky essence. So it should come as no surprise that I opted for a roasted butternut squash soup over a more traditional stovetop butternut squash soup. That earthy, roasted flavor really elevates this recipe!
butternut squash soup ingredients
Butternut squash soup is naturally ultra-creamy (without any cream). But if you do tolerate dairy, adding just a tablespoon or two of fresh butter when you’re blending definitely boosts the creaminess factor.
- Butternut Squash: You should be able to find butternut squash in abundance at the market during cold weather months. And good news – it’s super easy to roast the butternut squash halves.
- Onion and Garlic: I roast the onion along with the butternut squash and use a raw garlic clove. But if you’re not a fan of raw garlic, feel free to roast that in the peel as well!
- Vegetable Broth: If you’d like to keep the recipe vegetarian, opt for vegetable broth. But you can always swap in chicken broth as well.
- Ginger and Nutmeg: These two spices infuse the essence of fall’s best flavors into the soup.
- Maple Syrup: Just a touch of sweetness rounds out the flavors in the soup.
The beauty of this soup is that it’s naturally gluten-free, vegan, and vegetarian, which makes it perfect to serve to a large crowd during the holidays.
The Benefits of Roasting Butternut Squash
You could certainly make a traditional butternut squash soup on the stovetop, but there are two key benefits to roasting the butternut squash first:
- Depth of flavor: roasting any vegetable imparts an earthy, smoky, caramelized sweet flavor. And butternut squash is no different. In fact, it’s quite similar to roasting spaghetti squash.
- No dicing needed: when you roast the butternut squash no additional peeling or dicing is necessary. You just have to make one slice down the middle of the squash, then scoop the flesh out after it’s cooked. It’s far easier!
How To Make Butternut Squash Soup
- Slice it in half and remove the seeds. Preheat your oven to 425°F (220°C). Slice the ends off the butternut squash. Making a flat surface on the ends is key, so you can stand the butternut squash up on the bulb end and slice through it lengthwise. Once that’s done, use a spoon to scoop out the seeds and membrane.
- Season and roast. Transfer the butternut squash to a baking tray cut side up, coat with oil, and sprinkle with salt and pepper. Then, flip the butternut squash over so the cut side is down and roast for 60 minutes.
- Add the onion. After 30 minutes, spread a little oil on the cut side of the onion and add it to the baking tray, cut side down. Continue cooking for another 30 minutes, then remove the baking tray from the oven.
- Blend the soup. Once the butternut squash is cool enough to handle, use a large spoon to scoop out the flesh and transfer it to a high-powered blender. Remove the outer layer of the onion and add it to the blender along with the garlic, maple syrup, salt, nutmeg, ginger, and vegetable broth. Start with 3 cups of vegetable broth and add more to achieve your desired consistency. Blend on high for 1 to 2 minutes, until creamy. Taste the soup and add more salt and pepper if needed.
Storage Tips
- To store for the week: Any leftover soup can be stored in an airtight container in the fridge for 4 to 5 days. Perfect for a quick and delicious reheatable meal throughout the week!
- To freeze for later: It’s always a good idea to freeze leftovers or a second batch to enjoy throughout the winter months. Just store it in a freezer-safe container (like these Weck jars), and it will keep for up to 3 months.

Ingredients
Roasted Butternut Squash Soup
- 3 ½ pounds butternut squash
- 1 tablespoon avocado oil
- 1 small yellow onion, halved
- 1 garlic clove, peeled
- ½ tablespoon maple syrup
- 1 teaspoon salt
- freshly ground black pepper, to taste
- ¼ teaspoon ground nutmeg
- ¼ teaspoon ground ginger
- 3 to 4 cups vegetable broth
- Optional garnish: pepitas, parsley, and freshly ground black pepper
Instructions
- Slice it in half. Preheat your oven to 425°F (220C). Slice the ends off the butternut squash. Stand the butternut squash on end and carefully slice it in half lengthwise. Pro tip: the butternut squash is easier to slice through if you microwave it for 2 to 3 minutes.
- Remove the seeds. Use a spoon to remove the seeds and membrane.
- Season and roast. Transfer the butternut squash to a baking tray cut side up, coat with oil and sprinkle with salt and pepper. Then flip the butternut squash over so the cut side is down and roast for 60 minutes.
- Add the onion. After 30 minutes, spread a little oil on the cut side of the onion and add it to the baking tray, cut side down. Continue cooking for another 30 minutes, then remove the baking tray from the oven.
- Blend the soup. Once the butternut squash is cool enough to handle, use a large spoon to scoop out the flesh and transfer it to a high-powered blender. Remove the outer layer of the onion and add it to the blender along with the garlic, maple syrup, salt, nutmeg, ginger, and vegetable broth. Start with 3 cups of vegetable broth and add more to achieve your desired consistency. Blend on high for 1 to 2 minutes, until creamy. Taste the soup and add more salt and pepper if needed. Optional: while this is a dairy-free recipe, if you do tolerate dairy, adding just a tablespoon or two of fresh butter when you're blending definitely boosts the creaminess factor.
- Serve. Pour the soup into serving bowls. If you'd like, garnish the top with pepitas, parsley and black pepper.
Lisa’s Tips
- In the video above I added 3 garlic cloves as I love garlic and it was the last from my bulb, but it definitely overpowered the soup. Stick to 1 garlic clove as it’s written in the recipe. You can also add roasted garlic if you prefer a softer garlic flavor.
- When it comes to roasting veggies, I always recommend a heavy duty baking tray so it doesn’t bend and warp while cooking.
- I’m a massive fan of my Vitamix blender, but if you’re looking to buy one make sure to check out my Vitamix Comparison post.

I Enjoyed this very much but was a bit too sweet for my wife. Roasting the squash brings out its sweetness. Next time I won’t add the maple syrup. Also used roasted garlic and added a shallot.
Hi Edward – I’m glad you and your wife enjoyed this butternut squash soup!
I didn’t know what to do with butternut squash, so I googled it and came up with this recipe. YUM! I didn’t have powdered ginger, so I used two of the frozen lumps that you can buy in the freezer section. Everyone in the family loved it!
Hi Jeanne – Glad you found a recipe to make use of your leftover butternut squash!
Great squash soup. I peeled the skin off the squash as it came out of the oven. Much easier than scooping from the shell !
Hi Faye – I’m so glad you love this butternut squash soup!
So good!!!
I love how easy, delicious & healthy this soup is! I have to do a smaller squash since my vitamix container is on the smaller side, and use about 2-2.5 cups of broth. The texture is perfectly silky and the pepper ands such a nice kick!
Happy to hear this roasted butternut squash soup satisfies every time!
Eating it right now! I think I liked it best the first bowl I had. After that, it didn’t taste as good. I prefer something sweeter, which comes down to my personal taste. I find that adding heavy cream works best compared to regular milk, butter, or coconut milk. I used a quarter of a red onion because we didn’t have yellow onions on hand, so the onion taste was a little strong. That is entirely my fault and nothing on this recipe! I might try it again with a carrot added next time. Thanks for sharing!
Hi Alan – Thanks for your feedback! You can always tweak the recipe to your liking and add a bit more sugar and less onion the next time around.
This was delicious and a total hit with my family! Thank you!
I’m glad you enjoyed it, Eve!
Why so much salt in the completed recipe as written? “SODIUM: 1589MG” Do you have options to reduce this huge amount for one meal?
Hi Lorraine – unfortunately, the nutrition info is calculated automatically and it pulls in regular broth. Low-sodium broth should have far less sodium.
Hi, this looks delicious. I already have my butter squash cubed, should I cover it with foil in the oven as it wont have the shell to protect it from burning?
You don’t need to cover it with foil, but it will definitely cook much faster.
I made this to serve on Thanksgiving. Somehow I got onto another recipe that called for the squash to be peeled. After I peeled a couple pieces, I realized I was on the wrong recipe. I didn’t peel the remaining pieces. I will definitely peel it before roasting the next time. I lost a lot trying to scrape it off. After it was all put together, I tasted it before I froze it. The onion is a little stronger than I like. I think I’d use a smaller onion, or maybe even a portion of a sweet onion the next time. It’s going to be an awesome alternative to the standard squash dish.
LOVE this soup, followed recipe as written , creamy delicious and satisfying, made a double batch and sent half to freezer.
Wonderful! So happy you loved it, Eric!
This was so easy I had to try it. I used the fresh organic chopped butternut squash from Costco and roasted it in olive oil with the onion and I tucked the karmic cloves in with the squash. I roasted for 25 min till all was soft then put it all in my Vitamix blender. I used all the spices as Lisa recommended and thinned it all with chicken broth. It was wonderful!! How easy! Just pour it in bowls and serve! So creamy and delicious! No changes at all!
That’s a great time saving hack to buy pre-chopped butternut squash. So happy you loved the soup, Brenda!
This was AMAZING!!! So easy to make and so decadent. I roasted 2 cloves of garlic wrapped in foil and threw it in when I put in the onion. This is a keeper.
I’m so glad you enjoyed this butternut squash soup, Kannika!
I have made this before and I love it, can I freeze it.
Yes, you can definitely freeze it. It’s great for meal prep!
Love this version of the recipe! I left out the maple syrup, simply Bc we are trying to reduce unnecessary sugar intake, but the flavor is still incredible. Savory and delicious! and so simple and easy to make which makes it a weekly staple. Thank you!!
Thanks so much, Erin! I’m happy you enjoyed it. :)
I made this for thanksgiving. It was so easy. I loved how the onion was roasted with the squash. Everyone loved it. My family wants me to make more right away. Thank you, Lisa.
Do you think a stick blender would work for this recipe?
Yes, you could do that as well!
I only have a hand blender and it worked great!
This soup is so tasty. I made this for my gf friend and she loved it. We added salsa and a bit of cayenne pepper as I didn’t add much salt due to her restrictive diet. Sooo good!
Wonderful! I’m glad both of you enjoyed this butternut squash soup.
I followed the recipe but thought it was bland, yet overpowered by the garlic flavor which I don’t think belongs here. I even cut the clove in half after reading reviews. I added a little more maple syrup also and still could only taste the garlic. But I ate the soup and it grew on me. If I make this again I won’t be using any garlic.
Absolutely delicious! And so easy! This will definitely be in rotation.
Happy to hear you’re loving this butternut squash soup!
We host a gathering for our community every Friday evening. We call it Deep Soup and hope to spark conversations that build connections and ideas. This is a soup I will make again. There were no leftovers and I made our Instapot full! With gf skillet cornbread from your recipes, it was a hit.
Thank you for all you do in Downshiftology. It has been an inspiration in my gf journey.
I’m so glad this butternut squash soup was a hit for your community gathering!
A really nice “comfort food” soup for those chilly Canadian fall days. Delicious
This butternut squash soup is truly the best kind of comfort food!
Such a great and simple recipe! I have been wanting to make squash soup and had been looking at recipes for awhile. I am glad I found yours. I ended up roasting a whole glove of garlic when I added the onions and it gave the soup so much flavor. I didn’t have vegetable stock on hand, so I used chicken stock which was also very good! Thanks Lisa!
I’m happy to hear you found the butternut squash soup of your dreams, Patti!
When a recipe calls for 1 clove of garlic, I tend to give a major side eye and add a couple more and rhe recipe tastes great
DO. NOT. DO. IT. WITH. THIS. RECIPE.
You do not need just a bit more garlic.
That’s why I put the warning in the recipe notes. ;) When you blend garlic it amplifies the pungency.
Awesome soup WEIGHT WATCHERS friendly, if you eliminate the butter it’s only 3 points for the entire pot
Happy you loved it, John!
This turned out well! I loved that you can roast the onion (and garlic) along with the squash. I felt the nutmeg and ginger were a bit too strong for my taste, but it is a nice cozy soup. I also added a tablespoon of butter at the end–super yummm
I’m glad you enjoyed the soup, Liz!
I ended up adding more sweetness in the form of 6-8 tablespoons of brown sugar. One could add more maple syrup, but it might make the taste too maplely. I’m sure that’s a word, at least in Canadian english:)
There’s always room for more sweetness in this butternut squash soup!
