It is a variety of Cucurbita maxima, which also includes Hubbard squash, banana squash, and buttercup squash.

The flavor is remarkable, and among the sweetest of all squash and pumpkins. The texture is sometimes compared to that of a sweet potato. The shape is fairly round, and smooth, with few ridges, along with fibrous pulp and flat, cream-colored seeds that can be roasted to eat as a snack or for garnish. The flavor offers hints of chestnuts, and is enhanced by roasting

Kabocha squash is enjoyed throughout Asia, including in Korea, where it is used for making sweet rice porridge, and in Thailand, where it is a common ingredient in custards and other desserts, as well as curries. In Japanese cuisine, in addition to tempura, kabocha is frequently paired with miso paste, and is a favorite ingredient in shabu-shabu, or hotpot dishes, and for making croquettes. 

How to Cook With Kabocha Squash

Kabocha squash is incredibly versatile, as its flavor lends itself both to sweet as well as savory uses. Like all winter squash (as opposed to summer squash like zucchini), kabocha squash has a hard shell that softens with cooking, and the skin can be eaten. The contrasting colors of the dark green skin and vibrant orange flesh add an attractive visual dimension to dishes. 

The flesh can also be scooped out of the shell after cooking, or it can be sliced into wedges and then baked or roasted. Sautéing, simmering, and steaming are also common cooking techniques, and it can be cooked it in the microwave. Kabocha squash is ideal for making soups, sauces, jams, and chutneys. It works well as an ingredient in casseroles and gratins, curries, and stews, and the smaller ones are great candidates for being stuffed. 

With any of these methods, scoop out the pulp and the seeds first. Doing this after cooking, it is too easy to scrape away the tender flesh along with the pulp. So it is best to do this task before cooking. 

To roast a kabocha squash, wash it well on the outside and then dry it. Halve it through the stem with a heavy, sharp knife, scoop out the stringy pulp and seeds, and then brush the flesh with olive oil or melted butter. Sprinkle with kosher salt and freshly ground black pepper and roast, cut side down, on a sheet pan, in a 400 F oven for 25 to 30 minutes. When a sharp knife easily pierces the shell, it is done.
