Yaki Onigiri Bowl with Miso Glaze and Mushrooms
Why this recipe works
- Crisp rice edges: Firmly shaped short-grain rice holds together in the pan and develops a golden crust before the glaze is added.
- Deep savoury glaze: Miso, soy sauce and mirin create a glossy coating with saltiness, sweetness and fermented depth.
- Balanced bowl texture: Crisp grilled rice, tender mushrooms, shredded nori and fresh spring onion give the bowl contrast without needing extra toppings.

Texture tips
- Press the rice firmly: Compact triangles are less likely to break and make better contact with the pan, helping the outside crisp evenly.
- Glaze after a crust forms: Let the rice turn lightly golden before brushing on the miso mixture so the glaze caramelises rather than soaking in too early.
Common mistakes
- Avoid high heat with miso: Miso and sugar can catch quickly, so keep the pan at medium heat once the glaze is added.
- Do not shape the rice when fully cold: Rice is easier to mould while still warm; once cold, the grains are less sticky and the triangles can crumble.
Ingredient notes
- Use short-grain rice: Short-grain rice has the stickiness needed for neat onigiri that hold together during pan-grilling.
- Choose mushrooms with good browning potential: Mushrooms that can take direct heat without becoming watery work best, as the glaze should coat them rather than dilute in the pan.
Make-ahead tips
- Best served immediately: The rice has the best contrast when served straight from the pan, while the outside is crisp and the glaze is glossy.
- Re-crisp leftovers in a pan: Reheat the rice triangles in a dry frying pan over medium heat until piping hot and crisp again, warming the mushrooms alongside.

Ingredients
Instructions
- Rinse the short-grain rice in cold water until the water runs mostly clear. Tip into a saucepan with the water, bring to the boil, then cover and cook on the lowest heat for 12 minutes. Take off the heat and leave, covered, for 10 minutes to steam.
- Meanwhile, whisk the soy sauce, miso paste, mirin and caster sugar in a mixing bowl until smooth. Reserve about 1 tbsp of this glaze for finishing the mushrooms. Set the rest beside the hob with a spoon or brush for glazing the rice.
- Tip the cooked rice into a bowl and let it cool just until you can handle it comfortably. With damp hands, shape the rice into 4 compact triangles, pressing firmly so they hold together. Keep them on a plate while you heat the pan.
- Heat 1 tbsp sunflower oil in a large frying pan over medium heat. Add the rice triangles and cook for 3 to 4 minutes per side until lightly golden and a crust forms. Brush a thin layer of the glaze over each side as you turn them, then cook 1 minute more per side until glossy and lightly caramelised.
- Push the rice triangles to one side of the pan and add the remaining 1 tbsp sunflower oil to the empty side. Add the mushrooms and sauté for 5 to 7 minutes until browned and any liquid has cooked off. Stir in the reserved glaze and the toasted sesame oil, cooking for 30 to 60 seconds until the mushrooms are shiny.
- Shred the nori sheets into thin strips and thinly slice the spring onion. Divide the mushrooms between two bowls, top with two yaki onigiri each, then scatter over the nori and spring onion. Serve straight away while the rice is crisp.
Recipe notes
Tips
- For the neatest triangles, keep a small bowl of water nearby and dampen your hands between each onigiri so the rice does not stick.
- Keep the heat at medium when glazing so the miso does not catch; you want a gentle caramelisation and a glossy finish.
- If serving to anyone vulnerable, make sure the rice is piping hot all the way through before eating.
Substitutions
- Replace mirin with the same amount of water plus an extra 0.5 tsp caster sugar for a similar balance of sweetness.
- Replace sunflower oil with toasted sesame oil for a stronger sesame flavour, but use it sparingly as it can burn more easily.
Storage
- Refrigerate up to 2 days
- Cool leftovers quickly, then refrigerate in a sealed container. Reheat the rice triangles in a dry frying pan over medium heat for 3 to 5 minutes per side until piping hot and re-crisped; warm the mushrooms briefly in the pan alongside.
