Kabocha Squash Donburi Bowl with Miso Glaze

About This Recipe

Donburi, meaning simply bowl, is one of the most practical formats in Japanese home cooking: a mound of rice topped with a simmered or roasted component and a savory glaze, built for weeknights when there isn't time for multiple side dishes. Kabocha squash, with its dense, naturally sweet flesh, is a common autumn and winter donburi topping, often simmered in dashi, soy, and sugar (a preparation called kabocha no nimono). This version roasts the squash instead of simmering it, which concentrates its sweetness and gives it caramelized edges, then finishes it with a quick miso glaze that clings to the flesh rather than pooling underneath. Roasting also means you can prep rice and greens while the squash is in the oven, making the whole bowl come together with minimal active cooking. The finished bowl balances the squash's sweetness against salty miso glaze, the mild bitterness of quickly wilted greens, and a runny egg yolk that turns into a sauce of its own once broken over the hot rice.

Ingredients

Serves 4

• 700 gkabocha squash(seeded, cut into 1-inch wedges, skin on)
• 3 tbspneutral oil
• 2 tbspwhite miso
• 1 tbspmirin
• 1 tbspsoy sauce
• 1 tbsphoney
• 3 clovesgarlic(minced)
• 4 cupscooked short-grain rice
• 4 cupsbaby spinach or bok choy
• 1 tsptoasted sesame oil
• 4soft-boiled or onsen eggs
• 2 tsptoasted sesame seeds
• 2scallions(sliced)

Instructions

1. 1

   Roast the squash

   Heat oven to 425°F (220°C). Toss kabocha wedges with 2 tbsp oil, spread on a parchment-lined sheet, and roast 25-30 minutes, flipping once, until the edges are browned and a knife slides in easily.

2. 2

   Make the miso glaze

   Whisk miso, mirin, soy sauce, honey, garlic, and remaining oil together in a small bowl until smooth.

3. 3

   Glaze the squash

   In the final 5 minutes of roasting, brush the miso glaze generously over the squash and return to the oven until sticky and lightly caramelized at the edges.

   Add the glaze late, not at the start — miso and honey burn quickly at high heat if they go in too early.

4. 4

   Wilt the greens

   Heat sesame oil in a skillet over medium-high heat. Add spinach or bok choy and toss just until wilted, 1-2 minutes. Season lightly with a pinch of salt.

5. 5

   Assemble the bowls

   Divide rice among four bowls. Top with glazed squash wedges and wilted greens, then place a soft-boiled egg on top of each. Sprinkle with sesame seeds and scallions and serve immediately.

Variations

• •

  Swap kabocha for roasted sweet potato or butternut squash if kabocha isn't available.

• •

  Add a few slices of grilled or pan-seared chicken thigh for a heartier bowl.

• •

  Use the same miso glaze on roasted eggplant halves for a smokier, umami-forward variation.

Storage

Store roasted squash and rice separately in the fridge for up to 3 days. Reheat squash in a 375°F oven or skillet to restore some caramelization; microwaving works but softens the edges.
