This cozy vegan Roasted Butternut Squash Soup recipe is a warm, soul-soothing, autumn meal. It is creamy and buttery (without the butter and cream) and only 6 simple, plant-based ingredients. Personalize it with the toppings you love! (Vegan, gluten-free, oil-free.)

This butternut squash soup is made with only 6 plant-based ingredients!
It's so creamy, buttery, and full of warm flavor. (With no butter, olive oil, or heavy cream.)
I roast the squash first in the oven for two reasons: the flavor it brings out is amazing, and this way you don't have to mess with cutting raw squash into cubes which can be time-consuming.
Then we simply blend the buttery roasted squash with the rest of the ingredients, and boil/simmer in a medium pot. Nice and easy!

Ingredients for Butternut Squash Soup
For this recipe you will simmer in a large stockpot:
- Butternut squash: Try to find one that is about 3 to 3.5 pounds for this recipe.
- Yellow onion
- Garlic cloves: I like the flavor of fresh garlic cloves best, but you can easily substitute dried garlic powder instead in desired.
- Vegetable broth: Be sure to use low sodium if needed.
- Coconut milk: I use light and unsweetened. This adds another layer of creamy richness to the soup.
- Ground nutmeg
- Salt and black pepper to taste
Other flavors: Stir in fresh herbs such as sage, thyme, rosemary, bay leaf, etc. Fresh ginger, carrot, celery, or sweet potato are also possible additions.

Tools You'll Need
Blender: I use a 9-cup blender to puree this soup, however you can use an immersion blender instead if desired. (See notes below the recipe for guidance.) If your blender is smaller you may need to blend in batches.
Serving
Toppings are optional for additional flavor. A few ideas include:
- A swirl of pure maple syrup
- Maple-Vanilla Candied Walnuts: I really enjoy this addition for crunch and texture!
- Diced green apple
- Pumpkin seeds (pepitas)
- A dash of ground cinnamon or nutmeg
Storing
Store any leftovers in an airtight container in the refrigerator. We find they keep for about 3-4 days.
Freezer note: I have not tried freezing this recipe so I can't say if the texture would hold up well because of the coconut milk. However my best guess is it might freeze okay for up to 1 month.
