Kabocha squash (pronounced kah-bow-cha) looks like a green pumpkin or buttercup squash. It has a thick green skin and orange flesh. It was developed from the buttercup squash and the most common species are Cucurbita maxima and Cucurbita moschata.

The flavor is similar to other winter squash, but it also resembles a sweet potato and is usually sweeter than butternut squash.

Many people say it tastes like pumpkin, but some varieties taste like potatoes. The skin is tough but edible. It is often peeled so you can cook it faster.

Which nutritional figures you choose to use when checking kabocha squash nutrition depend on how you use the squash. If you are adding up the raw ingredients that go into a dish, you might use the raw figures. However, kabocha is cooked rather than eaten raw, so using the measurements and calories for the cooked squash will make sense for many uses.

Of course, the calorie count will change depending on how you prepare and serve your kabocha.

Adding butter, brown sugar, or syrup will add more calories to your dish.

Calories and Carbs in Kabocha Squash

If you want to use kabocha squash, you may wonder how many calories are in this Japanese winter squash. You will see confusing numbers for this quoted because the most reliable source doesn't specifically list kabocha squash.

Here is a close approximation.

The calorie content of kabocha squash isn't specifically listed in the United States Department of Agriculture Agricultural Research Service National Nutrient Database for Standard Reference Release 28. It's probably similar to other types of winter squash, such as butternut, buttercup, Hubbard, and acorn squash.

According to the database, one cup of baked winter squash cubes has 76 calories. It also has 18 grams carbohydrates and 5.7 grams fiber.

You may see figures that are a much lower quote. It could be that those sources picked the calorie count for raw cubes, which is about half at 39 calories per cup of raw cubes, 10 grams of carbohydrate and 1.7 grams of fiber.
