Homemade soups are a great way to increase your intake of nutritious and vitamin-rich veggies, feel cozy and satiated, and boost your immune system to prepare for the winter days ahead.
Kabocha squash, pronounced Kab-BOH-chah and sometimes called Japanese pumpkin, is our favorite orange-fleshed veggie to make soup.
Granted, we also love butternut squash soup and sweet potato soup. But kabocha, with its dense, meaty flesh and nutty and not-too-sweet flavor, makes the best soup.
Plus, it's rich in antioxidants, vitamin C, and beta-carotene, providing a wealth of health-boosting properties, from eye and skin health to heart and cell health.
To make it, we use our tried and tested technique of bake-and-blend, which in our opinion, makes the tastiest soup with minimal effort.
We roast all veggies, including garlic, onion, and spices, with the squash, then blend everything with veg broth and an immersion blender.
The result is a rich, creamy, and smooth soup with a nutty flavor between a pumpkin and a sweet potato, with earthy notes of sage and a mild sweet taste.

One of our favorite winter squashes, kabocha's dense texture and nutty flavor is perfect for making soup. Kabocha is sometimes called chestnut pumpkin or Japanese squash.
You can substitute other winter squashes such as pumpkin, butternut squash, delicata squash, and acorn squash. You can also use sweet potatoes.
We use whole garlic cloves that we crush and roast with the squash. First, roast the garlic with the peel so that it doesn't burn, then remove the peel before blending it.
White or yellow onions are best, but you can also use shallots.
We use fresh sage and rosemary to make the soup earthy and aromatic. They taste delicious in kabocha squash soup.
You can substitute thyme for rosemary.
We blend the roasted veggies with vegetable broth to turn them into soup. You can use reduced sodium vegetable stock if you like.
Extra virgin olive oil helps us roast the squash evenly. We prefer extra virgin because it tastes better and contains more antioxidants than regular olive oil.
Salt and pepper
Sea salt or kosher salt and freshly ground black pepper.
If you want to make kabocha squash soup with coconut milk, add a teaspoon of ground cumin, a teaspoon of turmeric powder, about an inch of grated fresh ginger, and a can of coconut milk before you blend the veggies.
If you do so, don't add rosemary and sage when roasting the squash.
Preheat the oven to 400°F or 200°C. Line a baking tray with parchment paper.
Cut the kabocha squash in half, scoop out the seeds with a spoon, then lay it flat on a cutting board with the cut side down.
With a sharp knife, cut the peel away, trying not to cut out too much of the flesh.
Chop the squash into chunks of about the same size, then add it to the baking sheet.
Add sage leaves, rosemary needles, chopped onion, and crushed garlic with the peel still on, and season with salt, pepper, and olive oil.
Toss with your hands, then arrange the veggies on a single layer without overlapping and bake for 30 minutes, or until the squash is fork tender.
Discard the garlic peel, transfer the veggies to a pot or dutch oven and add vegetable broth.
Blend with an immersion blender until the soup is smooth and creamy. Adjust the texture and consistency of the soup by adding more broth based on your preferences.
Note: you can use a regular blender if you don't have an immersion blender.
Taste and adjust with a pinch of salt if necessary. Then if you want the soup hot, simmer it on medium heat for a few minutes before serving it in a bowl with your favorite topping.
Tip: stir while the soup warms up to prevent soup bubbles making your kitchen dirty. The soup doesn't require to boil.

Kabocha squash soup with coconut milk
The creamy, milky, and nutty flavor of coconut milk pairs perfectly with kabocha squash. You'll get an Asian-tasting soup, which we love, with an even more velvety texture thanks to the fats in the coconut milk.
To make it:
- Roast the kabocha, onion, and garlic in the oven for 30 minutes, seasoned with olive oil, salt, and pepper. Just like our main recipe, but without rosemary and sage.
- When the kabocha is ready, add it to a pot with 1 cup of vegetable broth, 1 can of coconut milk, 1 teaspoon of turmeric powder, 1 teaspoon of ground cumin, and about 1 inch of peeled and grated fresh ginger.
- Blend until smooth, then warm up for a few minutes and serve.
Keep kabocha squash soup leftovers in an airtight container in the fridge for up to 3 days. Then, reheat in the microwave or a pot with a dash of water.
This recipe is suitable for freezing. Let cool down completely, then transfer to a freezer-friendly container and freeze for up to 3 months.
Thaw the soup in the microwave with the thawing function or the refrigerator over a few hours.
