Kabocha Squash Soup

Q: What is kabocha squash?

Kabocha Squash , sometimes referred to as Japanese pumpkin, is a type of winter squash with hard knobbly green skin. Despite its deep green outside appearance, on the inside a kabocha squash has a bright orange coloring. A kabocha squash is actually quite similar to a butternut squash. However, there are key differences. One of the main differences is the taste. A kabocha is even sweeter than a butternut, with a unique earthiness that's kind of similar to a chestnut or a russet potato. The first time I tasted the kabocha squash it reminded me of something else. At first, I couldn't quite put my finger on it but, after a while, it hit me that it tasted like a good old Gem Squash , which is a very common type of squash in South Africa. In terms of texture, it's somewhere between a pumpkin and a sweet potato. Kabocha is grown in California, Florida, Colorado and Mexico, as well as Japan and other countries around the world. It grows best in late summer and early fall.

Wine pairing

Chardonnay is the perfect pairing option for most squash and pumpkin recipes, and it works especially well with this roasted kabocha squash soup.

You could also go for a Pinot Gris or a Riesling, both of which complement the subtle sweetness and light spiciness perfectly.

Variations To This Recipe

Add chunks of cooked chicken to your soup to bulk it out and make it more filling.
You can use chicken or vegetable stock in this recipe. I've gone with vegetable stock, but feel free to go with your personal tastes.
This recipe calls for cumin to add some earthy spiciness to the flavor profile. If you want to add even more, you can add other spices into the mix. I recommend turmeric, paprika, cayenne pepper or chilli powder.
You can also add your favorite herbs to this soup. Parsley is a great garnish for any vegetable soup, but you can also add oregano, rosemary, mint, chives, thyme, marjoram, basil or sage... even wild garlic!

Popular substitutions

Kabocha squashes are fantastic, but not always easy to get hold of. If you can't find it, you can replace it with butternut squash, acorn squash or any other type of squash.
For a vegan version, add coconut milk in place of cream. If you want a creamy soup but prefer something lighter, you can also add sour cream.

Top Tip

To pick the perfect kabocha, look for one that is firm with a deep color. Also, try and find one that feels heavy for its size.
