Roasted Acorn Squash and Sweet Potato Soup

There are few things cozier than a bowl of homemade soup on a chilly day. Today’s Roasted Acorn Squash and Sweet Potato Soup is creamy, sweet, and bursting with flavor.
Roasted acorn squash and sweet potato are blended together with sautéed onions, garam masala, and coconut milk to create the most warming, nutritious soup.
Garam Masala is one of my favorite spice blends for soups as it is warm and fragrant, yet more delicate than curry powders. It doesn’t overpower other flavors and pairs extremely well with vegetables.
The addition of ginger adds a slight zing to every spoonful. This easy soup recipe is both vibrant and healthy, and is sure to brighten the darkest winter day!

Why You’ll Love This Soup:
- Comforting – roasted acorn squash and sweet potatoes make for a deliciously cozy, velvety soup ideal for the winter season. We love to pair it with crusty slices of sourdough bread or a big leafy salad.
- Flavorful – made with savory squash and root vegetables and layered with spices, including garam masala this soup comes together fairly quickly and is brimming with flavor.
- Dietary Friendly – this soup is naturally vegan and gluten free, making it great for those with dietary restrictions.

Ingredients You’ll Need:
- ACORN SQUASH: mild, buttery, and even nutty flavor, it’s not overly sweet, making for a great pairing with sweet potato.
- SWEET POTATO: starchy and sweet, look for potatoes with tough skin and firm flesh, without wrinkles, cuts, or bruises.
- SAUTÉED ONION: for aromatics.
- GARAM MASALA: a North Indian spice mix typically made with black and white peppercorns, cloves, cinnamon, cumin seeds, and cardamom pods. Warmly spiced, mild, and extremely versatile. Look for it in the spice aisle or try this recipe for homemade garam masala.
- GROUND GINGER: slightly peppery, ground ginger adds a pungent, warming bite.
- BROTH: low-sodium vegetable broth is my preferred choice for homemade soups and stews these days. Feel free to substitute it with a delicate chicken broth if you prefer.
- COCONUT MILK: rich and fragrant, canned unsweetened coconut milk is a fantastic way to add that unmistakable creamy texture and flavor without needing dairy-based cream. If you don’t enjoy coconut, substitute with 1/4 cup heavy cream or more to taste.
- LIME JUICE: a touch of freshly squeeze lime juice just before serving helps balance the natural sweetness of the squash and sweet potato.
- SALT + PEPPER: – season and taste as you cook.

How to Serve This Soup:
While this soup is excellent on its own, I love to serve it with slices of crusty sourdough and a bright and acidic leafy salad (this everyday lemon vinaigrette is a great choice).

Roasted Acorn Squash and Sweet Potato Soup
Equipment
Ingredients
- 2½-3 lb whole acorn squash sliced lengthwise in half and seeds scooped and discarded
- 2 medium sweet potatoes roughly 1 lb
- 2-3 tablespoons extra virgin olive oil divided
- kosher salt
- 1 medium yellow onion small dice
- 1½ teaspoons garam masala
- ¾ teaspoon ground ginger
- 3½-4 cups (840-960 mL) low-sodium vegetable broth as needed
- ⅔ cup (160 mL) full-fat coconut milk plus more for garnishing
- ½ lime for juicing
- freshly ground black pepper
Instructions
- Preheat oven to 400°F (204°C). Carefully slice the acorn squash in half lengthwise. Scoop out and discard the seeds and guts. Slice the sweet potatoes in half lengthwise. Set the vegetables on a half sheet pan. Drizzle the cut-sides of the sweet potato and squash with 1 to 2 tablespoons olive oil and season with salt. Turn the squash and sweet potatoes cut-side down on the pan.
- Roast for 45 to 60 minutes, or until both the potato and acorn squash flesh is very soft and meets no resistance when pierced with a knife (note: if the sweet potatoes finish, remove and set aside while you finish roasting the squash). Remove from the oven and when the pieces are cool enough to handle, scoop out the squash and sweet potato flesh – discarding the skins. Set aside.
- Heat the remaining 1 tablespoon of olive oil in medium-sized soup pot. Add the diced onion and a generous pinch of kosher salt, and sauté over low heat until soft and completely translucent, roughly 5 to 7 minutes. Add the garam masala and ground ginger. Stir and cook for an additional minute or two, or until fragrant. Add the 3½ cups broth and roasted squash and sweet potato. Bring to boil, then reduce to low and simmer for 10 to 15 minutes, stirring occasionally.
- Puree the soup in a high-powered, large capacity blender, such as a Vitamix, until very smooth. You may need to do this step in batches. Return the blended soup to the pot and bring to a very low simmer. Add the coconut milk and juice of ½ lime and stir until incorporated. If too thick, add an additional ½ cup broth or splash of water. Season to taste with salt and pepper, and another pinch of garam masala or ground ginger if desired.
- Serve and drizzle with leftover coconut milk and extra virgin olive oil.

OMG – this is delicious!!! Made a butternut ginger squash the other day and when I said I wanted to make this my boyfriend, said – it can’t be better – this was SOOOO MUCH BETTER – just delicious – great recipe!
This makes me SO happy! 🙂
What a great recipe! Made it for dinner the other night and my (picky) husband says, “mmmm… very Fall-y”. And It made TONS OF SOUP! Lunch all week 😀 Thanks!
Thank you so much Jeni!! So glad you enjoyed it, and I really appreciate you taking the time to give me the feedback. Soup leftovers are the BEST leftovers 🙂

Most soup recipes feature butternut squash, not acorn. That was intriguing to me. Pinned.
Thanks so much Suzanne!
This recipe is excellent. I have made it several times with different vegetables (butternut squash, acorn squash, carrots, and sweet potatoes) and even tried a sage and butter flavor in place of the garam masala. It is delicious everytime. Thank you for sharing!!!

Man, this is perfect for fall — and we’ve gotten obsessed with acorn squash over at my house! Wish I had a big bowl right now.
Thanks so much Meg! I keep buying more and more squash every time I go to the store. I can’t help it–especially when I know it won’t be there in a few months time 🙂
I always feel that pumpkin and sweet potatoes are an either or situation. This soup proves me wrong, obviously! So good looking Laura! And my garam masala never seems to decrease, I have a ton too.
Glad I’m not the only one with a massive stash of garam masala, haha! I don’t use it nearly enough–but it works so well with so many of my favorite fall foods. Thanks so much Paula !!
I can just imagine the amazing aroma as this soup bubbles on the stovetop! What a wonderful autumn soup. It looks so delicious, Laura!
Thanks Georgia!! I was eyeing your stuffed pepper soup the other day–looked so good.
Love soups too. Made one today also with coconut milk. Your recipe and pics are awesome!
Ooh what did you make?? I love hearing new recipe ideas (especially ones that involve me having to buy more coconut milk. I have a serious problem when it comes to that stuff.)
Thank you so much for the kind words, Archana!! It means a lot 🙂
Fall IS totally the best cooking/baking season! And soup is like a bowl full of fall! The the way you flavored this!
Yes, it totally is. Basically any time that I can get away with cooking whatever I want (and not sweating profusely in the process), I’m incredibly happy. Thank you, thank you!
Squash and sweet potatoes are my autumn dream come true! Add in coconut and I’m even more in love! 🙂
I keep buying more and more squash and sweet potatoes at the store every week. Can’t get enough!! Thanks Sues!
I am not finding your recipe for squash and sweet potato soup. It sounds wonderful!
Coconut milk can do no wrong! Pinned!
So very true. I have a problem when it comes to coconut milk. I literally have to stop myself, otherwise every other recipe on the blog would include it, haha! Thanks so much Averie!
This looks delicious! I love the addition of garam masala (one of my favorites that I use in spicy potatoes with yogurt gravy!). I’m thinking this might be how we start off Thanksgiving, which we are hosting this year 🙂
Ooh that potato dish sounds amazing. Let’s swap!!! 🙂
Sounds delicious! Fall is my favorite season for food too : )
Isn’t it the best?!? Thanks so much Natalie!!
Looks good Laura! I have yet to make a soup this fall. Maybe that is because I don’t have a kitchen right now?
Yeah, that might explain that… Just spoke to Brian today! Glad you’ll have access to a new fancy kitchen this weekend!
This is gorgeous!! Wow and the flavors sound incredible! I love making soup too, it is the perfect way to spend a fall day!
Yes! I love how relaxing it is to just chop tons of ingredients and cook a one pot meal. Thanks Tieghan! 🙂 Now I just need a side of skillet cookie….
Gorgeous! I love soups like this — so perfect for fall.
Thanks so much Rachel!! Can’t wait to make more during the coming months…
beautiful pictures for a yummy soup! you can never have too much squash!
Thanks Ali! Nope, you can never have enough squash. 😉
I’m actually so scared to make this. It sounds amazing, but curry always makes me sick (and some other Indian spices). But the truth is I have no idea which spice in curry spices is the culprit so I really want this one to be okay. Will probably make a small bowl with the garam masala to see how I feel then just add nutmeg to the rest to see how it goes.
How did that work? I am allergic to something in Curry powder…
Hey Charlene? Did you mean that you tried this? Not sure what your comment means!
