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 roasted butternut squash soup

  • 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.

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. You want to have the butternut squash, seed it, peel it and then cutting into into small 2 inch cubes. I add olive oil, maple syrup salt/pepper  and cinnamon, and roast them.

While the butternut squash is in the oven, I get started on other parts of the recipe. I saute an onion with olive oil, then add garlic. When the butternut squash is fork tender, I add it to the pot.

Next I add the vegetable broth and I blend it all with an immersion blender. The soup is pretty much good to go from here, but I prefer adding some oat milk to the mixture just to make it more creamy. Oat milk is plant-based and has a pretty neutral taste that blends well into this soup.

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
  • Thyme
  • Sage
