One of my favorite soups to make during the fall and winter is this Roasted Butternut Squash Soup. This classic recipe literally only needs butternut squash and a couple other staple pantry ingredients, so I find myself making it quite often in the fall. I think you will too! Be sure to check out my other warming and cosy soup recipes.
Why I love this soup recipe
- It’s vegan – There’s no milk, cream or butter in this recipe, making it completely vegan, but completely creamy and rich at the same time.
- It’s low carb – And also keto-friendly too! That makes it a great soup if you’re trying to limit carbs at dinner or looking for a lighter fare in the evening.
- It uses basic ingredients – As long as you planned ahead with the butternut squash, the rest of the ingredient list is super simple. The remaining ingredients include olive oil, onions, garlic, maple syrup, vegetable broth, nutmeg and thyme.
- It has an amazing roasted flavor – There’s just something wonderful about roasting vegetables to use in soup. It brings out that smokey flavor of the butternut squash and makes it more caramelized and more tasty than simply boiling the squash.
- Butternut squash: Cut the whole butternut squash in half before removing the seeds. Cut into cubes so that it roasts quickly. You can by prepared squash at stores for convenience.
- Maple syrup: I like to roast the butternut squash in a little maple syrup for a touch of sweetness. Honey can also be used if not vegan.
- Seasonings: Salt, pepper and cinnamon.
- Onion and garlic: Onion and garlic are a great way to add flavor to this soup so that it’s not bland.
- Broth: You can use homemade vegetable stock or store bought. If not vegan or vegetarian, chicken stock will work well too.
- Oat milk: This plant-based milk gives the soup a creamy texture without the need for dairy. Coconut milk can be used and would add a sweeter flavor that’s very delicious, or unsweetened almond would work great too. Use a dairy milk or half and half if not vegan.
How do you make roasted butternut squash soup
It’s all about the roasted butternut squash in this soup. It’s literally the key ingredient. Everything else just kinda supports it.
First, grab my tips for the best way to cut butternut squash.
- Half the butternut squash, seed it, peel it and then cut into into small 2 inch cubes.
- Toss in oil and seasonings and roast.
While the butternut squash is in the oven, I get started on other parts of the recipe.
- Saute an onion with olive oil, then add garlic.
- When the butternut squash is fork tender, add it to the pot.
- A the vegetable broth.
- Blend everything together with an immersion blender and stir in the oat milk.
When it’s all done, I usually add on a dollop of plant-based yogurt, which is thicker than the oat milk. That really gives it a more creamy consistency and rich taste. Throw on some fresh thyme leaves and dig in!
What spices go with roasted butternut squash soup?
Like I mentioned before, the soup really is all about the squash, and everything else just supplements that flavor. So the spices you use here can really change up the flavor of the soup and make it unique. What I would recommend is a mixture of aromatic spices (like cinnamon) with a little bit of heat (hello cayenne pepper) and a touch of fresh seasonal herbs (think of thyme or sage). We want a combination of sweet, spicy and herbaceous.
Here’s a list of spices that I think work wonderfully well with this roasted butternut squash soup. You can mix and match however you’d like. I like to keep it simple with only nutmug, black pepper and fresh thyme for serving.
- Ground allspice
- Ground cinnamon
- Ground nutmeg
- Ground ginger
- Cayenne pepper
- Black pepper
Tips to make this recipe
- Roast the butternut squash until it is fork tender. It will take around 40 minutes depending on how large or small you cube it.
- Feel free to mix and match the spices so that the soup is just to your taste. It’s easy to turn this into a sweeter or more savory soup depending on your tastes. Try some chili flakes or cayenne to make it spicy.
- Use an immersion blender to make the soup smooth. This is the easiest way, or you can use a stand blender, but be careful as it will be very hot. Alternatively, leave it as is if you like it chunky.
- Make a double batch. This soup recipe is perfect for make ahead and freezer meals and the recipe is easily doubled. Let cool full before storing.

Cook the onions until they soften and become translucent, about 4-5 minutes. Then add the garlic, and stir frequently until fragrant, about 30 seconds to one minute.
- When the butternut squash is cooked and fork tender, transfer it to the pot with the onions and garlic mixture. Next, add the vegetable broth. Bring the contents of the soup to a boil, then cook on medium heat for 15 to 20 minutes, stirring occasionally.
- Using an immersion blender, blend the soup until there are no more chunks of squash left. Stir in the oat milk. Serve hot with a dollop of yogurt and fresh thyme, if desired.
