📋 Ingredients
Here are the ingredients (amounts are in the recipe card below).

- Kabocha: We use ⅛ Kabocha squash. Find the one already cut into a quarter size. If whole kabocha squash is the only option, this post "How to cut Kabocha squash" would be helpful.
- Komatsuna: Komatsuna is a typical green leaf in Japan. You can substitute it with other green vegetables.
- Tofu: Tofu is a popular ingredient in miso soup. Both silky and firm work well.
- Niboshi for dashi: Niboshi is dried anchovy, and we use them for making dashi (soup stock) (See niboshi dashi recipe). I like to use niboshi dashi for miso soup as it brings an authentic flavor, but you can substitute it with 2-3 teaspoons of dashi granules to save time.
- Miso paste: Miso paste is the key ingredient in miso soup. It's made with soybeans, koji, and salt. Please pick an authentic miso paste that doesn't contain any additives.
🔪Instructions
