What is Kabocha Squash?

Kabocha squash, also known as Japanese pumpkin, is a type of winter squash revered for its sweet and nutty flavor. It typically has a dark green, bumpy skin and vibrant orange flesh. Rich in essential nutrients like vitamin A, vitamin C, and fiber, kabocha squash is not only delicious but also offers a range of health benefits, making it a popular and healthy choice for many people.

Health Benefits of Kabocha Squash

Ingredients Equipment Method Video

Ingredients

1 small kabocha squash aka Japanese Pumpkin
1.5 cans Cream of Mushroom soup 284 ml
1 can water

Equipment

1 steamer
1 soup pot

Method

Fill an Always Pan with 3-4 cups of water and put the steamer basket on top. Begin by steaming the kabocha squash until a knife easily pierces through (roughly 20 mins depending on size of squash). This crucial step not only softens the flesh but also makes removing the skin a breeze.
Alternatively, you can also use a wok or soup pot along with a steaming rack and plate to hold up the kabocha squash.
Once a knife easily pierces through the flesh, remove from steamer basket using oven mitts and place on cutting board. The kabocha squash will be very hot so handle with care!
Carefully remove the peel using a sharp knife and cut the squash in half. Scoop out the seeds and cut into smaller chunks.
For any harder pieces of squash that might need a little extra attention, simply microwave them for an additional minute or two.
Remove the steamer basket, and transfer all the squash back to pot. Using a potato masher, mash the squash as best you can. Then turn the heat on to medium.
Add cream of mushroom soup and water to the pot. Adjust according to how runny or thick you like your soup. Using a potato masher, mash and mix everything together until the soup is well combined.
Reduce heat to low and simmer for another 10 minutes stirring constantly.
Serve how and garnish with a sprig of parsley or cilantro, along with a few drops of truffle oil (optional).
