What is Kabocha no Nimono?

How to Cut Kabocha (The Easy Way)
Kabocha is delicious—but notoriously hard to cut. Here’s how to do it safely:
Step 1: Soften the kabocha (optional but recommended)
Microwave half of the kabocha for 2–3 minutes to soften it slightly.
Step 2: Cut through the stem
Carefully insert your knife into the side of stem and press down slowly.
Step 3: Split it apart
Rotate and repeat, then gently pull apart with your hands.
Step 4: Remove seeds & prep
Scoop out seeds, trim some of the tough skin if needed, and cut into chunks.
RECIPE
Servings: 3-4
Time: 30 min
Ingredients:
1/2 pc medium kabocha
2 tbsp sugar
2 tbsp soy sauce
2 tbsp mirin
2 cups water, or enough to cover the kabocha
Instructions:
Prepare the Kabocha
Remove seeds and trim the stem.
Cut the kabocha into bite-sized chunks.
Arrange in Pot
Place the kabocha in a pot with the skin side facing up.
This helps the pieces hold their shape while simmering.
Add Seasonings
Add water, sugar, soy sauce, and mirin.
Simmer Gently
Once it starts boiling, turn it on low heat.
Simmer for 20–25 minutes over medium heat.
Let It Rest (Optional but Recommended)
Let the kabocha sit in the broth for a few minutes after cooking—it absorbs even more flavor.
FAQ
Can I eat the kabocha skin?
Yes! The skin softens during cooking and is completely edible.
Why place the skin side up?
It helps prevent the kabocha from breaking apart while simmering.
Can I make this ahead of time?
Yes—this dish actually tastes better after resting as it absorbs more flavor.
How long does it keep?
Store in the fridge for up to 3 days.
Can I reduce the sugar?
You can slightly adjust it, but the sweetness balances the soy sauce.
