What is Kabocha Squash?

Kabocha squash, also called Japanese pumpkin, is a round winter squash with a dark green exterior and bright orange flesh. It looks like a large acorn squash.

Kabocha squash tastes like a combination of sweet potato and pumpkin - it has rich, velvety flesh with a mild flavor. It has edible skin (like all winter squash) once cooked.

Kabocha is popular in Japanese cooking but it's also used in Thai and Korean dishes as well. You can bake it, roast it, simmer it, and puree it like other winter squash. The seeds can be roasted like pumpkin seeds as well.

You can find kabocha squash at an Asian grocery store or the farmer's market. They're harvested in fall like other winter squash.

How to Make this Recipe

Prepare the Squash - Cut the squash in half with a large, sharp knife. The outer skin is tough, so be careful with the first slice. You can leave the skin on, once simmered it becomes tender. Scoop the seeds and stringy insides out of the center. Chop the squash into 2-inch pieces.

Make the Sauce - Combine the water, soy sauce, mirin, brown sugar, and instant dashi in a large stockpot over high heat. Stir and bring to a boil for 2 minutes. 

Simmer the Squash - Add the squash to the pot. Stir and cover the pot with a lid. Bring to a boil and reduce to medium heat. Let simmer for 8 to 10 minutes or until fork tender, stirring occasionally.

Plate - Serve the squash on its own as a side dish or pair it with seasoned rice, sliced green onions, and sesame seeds for a main course.

Tips for Making this Recipe

Cooking Tips - Prick the squash with a fork to test tenderness. If it slips in easily, the squash will be tender enough.

Specialty Ingredients - This recipe calls for instant dashi, this is the brand I used.

Recommended Tools - I highly recommend using a large chef's knife to cut the squash. Kabocha squash has a tough outer rind, so you need a large, sharp knife to cut it!

Storing Tips - The cooked squash can be saved in the refrigerator for up to 5 days in an airtight container.

Diet/Allergy Alternatives - If you want to keep this recipe vegan or vegetarian, substitute the instant dashi for vegetarian dashi or leave it out.
