My favourite part of fall are the warm and cozy, comforting fall soups. Creamy roasted butternut squash and cauliflower soup has all the fall feels and is vegan and gluten-free. It's packed with butternut squash and cauliflower, mixed with onions and garlic and fresh herbs, and a little coconut milk for that extra creaminess. So so delicious. Plus, it's super easy to make. Think of a one sheet pan meal that is blended into a soup.
If you are like me and are a fan of roasted butternut squash soup or butternut squash and apple soup, then you will love this. It makes the perfect starter or side to add to your Thanksgiving holiday menu or for any meal this fall.
Side note - that is my very obedient one year old stepping in as my hand model, since Danny (the usual model) was at his day job.
What is in this Roasted Vegetable Soup?
- butternut squash
- cauliflower - cauliflower really adds a silky creaminess to this soup.
- onion
- garlic
- fresh sage - you could also substitute with rosemary or thyme, or use a combination of the three.
- olive oil
- salt and pepper
- vegetable stock
- coconut milk - this also adds a little extra creaminess. I used coconut milk to keep the recipe vegan, but you can substitute with regular cow's milk if you prefer.
You will also need a large ½ pan baking tray, a food processor or blender, and a large pot.
How to Make the Best Roasted Butternut Squash and Cauliflower Soup
In a large ½ pan baking tray, combine butternut squash, cauliflower, onion, garlic, sage and olive oil. Add salt and pepper to taste, and toss to combine. Bake in a preheated 425 F oven for 20-25 minutes, until vegetables are soft and tender.
Transfer vegetables into a food processor or blender (in 2 batches if needed). Add 2 cups of stock and puree until smooth.
Transfer soup to a large pot, add remaining stock, and stir to combine. Bring soup to a simmer, and stir in coconut milk. Season with more salt and pepper, to taste. Serve with a drizzle of coconut milk and fresh herbs or toasted pepitas on top.
Tips and Tricks
- Do I have to roast the vegetables? Roasting the vegetables adds an extra depth of flavour to the soup and really intensifies the flavour. But you can absolutely skip this step and just cook the soup in a pot. The soup will still be delicious. Simply, saute the oninos and garlic, then add everything else and simmer for about 25 minutes, or until vegetables are tender. Puree, add coconut milk and serve.
- How thick should this soup be? As thick as you would like! I like my soup right in the middle. If you find that it is too thick, add some water until desired consistency is reached. If you find the soup is too thin, continue to simmer, uncovered, to thicken it up until you reach your desired consistency.
- How to serve: Serve this butternut squash soup with a side of homemade ciabatta bread or crusty no knead bread for dipping. Small batch sourdough bread is also one of my favourites to pair with this.

Notes
Equipment used: a large ½ pan baking tray, a food processor or blender, and a large pot.
How to cook in one pot instead: Roasting the vegetables adds an extra depth of flavour to the soup and really intensifies the flavour. But you can absolutely skip this step and just cook the soup in a pot. The soup will still be delicious. Simply, saute the oninos and garlic, then add everything else and simmer for about 25 minutes, or until vegetables are tender. Puree, add coconut milk and serve.
How to adjust the consistency: If you find that it is too thick, add some water until desired consistency is reached. If you find the soup is too thin, continue to simmer, uncovered, to thicken it up until you reach your desired consistency.
How to serve: Serve this butternut squash soup with a side of homemade ciabatta bread or crusty no knead bread for dipping. Small batch sourdough bread is also one of my favourites to pair with this.

This soup was AMAZING on our Thanksgiving this year. No one expected it to taste so delicious, thank you!!! The only issue I had was that the soup wasn’t exactly creamy…I used a food processor but the consistency was kind of mealy. Any tips??
Thanks!

Thank you Julia! To make it extra creamy, I would suggest pureeing it in a blender to get it smoother.
Rebekah says
I tried the one-pot option and cooked everything on the stove top. I also didn't have fresh sage, so I substituted with dry. It was still flavorful and delicious! Nice and filling too. Thanks for a fantastic vegan dish!

Thank you so much for sharing Rebekah! So happy you liked the recipe.
Heather says
I had to use double the coconut milk to this recipe and also added Cinnamon sticks and turmeric to help balance it out. I paired it with a grilled cheese and used a fresh sourdough loaf for the bread and provolone for the cheese and added fresh jalapeños and Yellowbird Habanero hot sauce to the sandwich. It tastes really good when you dip it in the soup! Thanks for the recipe! Excited to try out more from your page 🙂

Thank you, so glad you liked the recipe and thanks for sharing your tweaks. Also, that fresh sourdough sandwich on the side is making my mouth drool!
Shelley says
I love your description of this recipe as a sheet pan meal blended into a soup! That's a perfect way to look at it - uncomplicated and deliciously warming on a chilly evening, with so much veggie nutrition, too! Fresh sage is an absolute favorite of mine, especially with fall recipes and winter squashes - the ideal addition!
