What is kabocha?
'Kabocha' (カボチャ, 南瓜) is a Japanese word that refers to any kind of 'pumpkin.' However, in english 'Kabocha' refers specifically to a sweet, Asian variety of squash popularly used and cultivated in Japan; also known as Japanese pumpkin. The flavour and texture is quite different from the Western pumpkin, and cooking methods are, as well.
The flavour is described as nutty chestnut crossed with purple sweet potato. And the texture is somewhere between a pumpkin and a sweet potato. It is in season from late summer through early autumn. A suitably ripe kabocha will be deep green in colour, hard, and feel quite heavy.
Because of the squash's sweet flavour, it is often used in desserts and baked goods in Japan. The rind of the kabocha squash is edible, however, we will remove it in this recipe to give the soup its beautiful orange colour.
Substitutions
Kabocha squash - The best substitute is the buttercup squash. Alternatively, acorn squash is a decent substitute as well.
Beef broth - Substitute with chicken or vegetable broth.
Variations
Vegetarian - Substitute the beef broth with vegetable broth.
Vegan - Substitute the beef broth with vegetable broth, and the whole milk and heavy cream with canned, unsweetened, whole-fat coconut milk.
Instructions
For this recipe that makes 3 servings (or 4 small), you will only need a quarter of a kabocha (or double the whole recipe to make a bigger batch).
Cut the kabocha in half, then cut one in half again to get a quarter. Kabocha is surprisingly hard, so be very careful of your fingers when cutting it.
Remove the seeds from your quarter of kabocha, then wrap it in plastic wrap. Microwave it for 4 minutes to soften the squash and make it easy to remove from the rind. (Note: To make this recipe without a microwave, see the note at the bottom of the recipe card below).
Be careful handling the hot kabocha. Cut it off of the rind and into roughly equal sized pieces. Set the kabocha pieces aside for now.
Melt butter in a saucepan over medium heat. Add the sliced onion and sauté until it begins to soften.
Stir in the kabocha and sauté it with the onion for another minute.
Pour in the broth. Bring the soup just to a boil, then cover it with a lid and reduce the heat to low. Allow it to simmer for 20 minutes.
Using an immersion blender purée the soup. Or, you can use a blender to purée it in batches.
Pour in the milk. Stir while you wait for the soup to get hot. Don't allow it to come to a boil. Season to taste with kosher salt and freshly ground black pepper.
Optionally, drizzle with a touch of cream and garnish with chopped fresh parsley. Your Japanese kabocha soup is ready to enjoy! I recommend dipping some warm, crusty bread into it.
Equipment
An immersion blender makes blending this soup into a purée very quick and easy. You can also use a blender to do this.
Storage
Store leftover soup in an airtight container in the refrigerator for up to 2-3 days.
Tip
The hardest part of making this recipe is cutting the squash. They're really hard. If you really can't cut through it, try putting the squash into the microwave for 1 minute to soften it slightly. Be careful to not make it too hot to handle.
