For a carrot + apple version try our fan favorite recipe from years past.
The Butternut Squash / Pumpkin
Sweet and nutty butternut squash is my go to favorite of winter squashes for making creamy soups. It has a mild flavor with smooth buttery flesh, not stringy as most winter pumpkins. All things considered, you could certainly make this soup with acorn squash, kabocha, sweet or seminole pumpkin. The depth of flavor comes from roasting the butternut squash until lightly caramelized around the edges for all the natural sugars to concentrate. The absolute best!
About the Leeks
So much flavor in this vegetable! Grab a large one as you’ll need about 2+ cups for your base. Slice and rinse well as leeks grown underground and tend to collect a lot of sandy soil in between the layers. Although the entire leek is edible and delicious, In this recipe I suggest only using the white and pale green parts. The only reason for this is so that your soup will end up a beautiful golden color everyone is sure to want to dive into with a big spoon.
Ingredient Tips + FAQ
- Aromatics – No onion to be found here, instead I used a large flavor packed leek and a celery rib. You can of course expand on the concept and add some extra root veggies like carrot, sweet potato or parsnips but not necessary at all.
- The Herbs – Sage, rosemary and thyme deliver outstanding fall flavor to your soup. Frying some sage leaves until crispy will take your presentation over the top, a treat I would indulge in during holiday season.
- Cashews – An optional ingredient but really makes your soup next level creamy and silky. Alternatively you could use a cup or so of almond or cashew milk or add a cup of white beans instead. This will help balance out the butternut flavor.
- Add Ins – crispy roasted broccoli, wilted kale, baby spinach, cooked lentils, sautéed mushrooms, pan seared tofu cubes, or your favorite roasted veggies. Go Wild!
- Water Vs Veggie Stock – Just use water! Between the roasting process, the leeks and the herbs there is just so much delicious and complex flavor happening, save your stock for something else.
- Make it Oil Free – Yes you can adapt the soup to be extra healthy WFPB + Plantricious by omitting the oil and using veggie broth or water instead.
- Garnish – A drizzle of homemade cashew cream, crispy fried sage leaves, some of the reserved roasted butternut balanced by a few dried cranberries make this soup exquisite and absolutely perfect for the festive Thanksgiving table.

You’ll also love…
An outstanding soup perfect for fall and the holiday table. I love that the recipe calls for water instead of veggie broth yet the flavor is really wonderful.
This is the most amazing recipe I have ever seen. I am going to make it for dinner tonight and I know my family will absolutely love it.
Is there any alternative to cashews?
Hi Angelina, you could always just use a splash of your favorite plant based milk, however there isn’t anything really quite like cashews. You could try almond or sunflower seeds too which would work just not quite the same silky and luscious result. Let me know how it goes.~ Florentina Xo’s
