Oyakodon

Oyakodon — "parent and child bowl" — is chicken and egg simmered together in a dashi-soy broth and served over rice. The egg is deliberately not fully cooked; the soft, barely-set curds coat the chicken and rice in a way that hard-cooked egg cannot.

Slice the onion into thin half-moons. Cut the chicken into bite-size pieces, about 2cm.

Combine the dashi, soy sauce, mirin, and sugar in a small frying pan or donabe (the Japanese earthenware pot designed for this dish). Add the onion. Simmer over medium heat for 3–4 minutes until the onion is just softened.

Add the chicken pieces in a single layer. Cover and cook for 4–5 minutes until the chicken is cooked through. Flip once if needed.

Beat the eggs lightly — do not over-beat; some streaks of white and yolk are fine. Pour half the egg over the chicken in a circle from the outside in. Cover and cook for 30 seconds. Pour the remaining egg over the top. Cover and remove from heat immediately.

The residual heat sets the egg to a just-cooked, custardy consistency. It should not be runny, but it should not be fully set. Timing is the whole skill of this dish.

Slide over a bowl of hot rice. Scatter sliced spring onion on top. Serve immediately.

Method

Oyakodon is a discipline in egg-cookery: the eggs must remain custard-soft, barely set by residual heat alone. This is the opposite of scrambled or omelette work — you're leveraging carryover cooking to stop the proteins at the exact moment they turn from liquid to curd. Overshooting by thirty seconds turns them rubbery and kills the dish.

Slice the onion into thin half-moons. Cut the chicken thigh into roughly 2cm pieces — uniform size matters so everything cooks at the same pace. In a frying pan or donabe (the Japanese earthenware vessel is preferable, as it holds heat more evenly and keeps the broth at the right simmer), combine the dashi, soy sauce, mirin, and sugar. Bring to a bare simmer over medium heat and add the onion. After three to four minutes, the onion should be translucent and just beginning to soften — it will continue to cook in the broth, so stop before it collapses.

Arrange the chicken in a single layer across the surface and cover immediately. The liquid should bubble gently at the edges; if it roils, reduce the heat slightly. Cook for four to five minutes. The chicken is done when it feels firm to a nudge with the spoon — there should be no grey-pink at the thickest part. This is where dashi does its work: the stock's umami from kombu and bonito masks any gaminess and keeps the broth tasting clean and savoury, not muddied.

Beat the eggs with a fork until just combined — aiming for some visible streaks of white and yolk. This prevents the whites from setting faster than the yolks, which would give you rubbery shreds instead of a smooth curd. Pour half the beaten egg in a thin stream around the perimeter of the pan, spiralling inward. Cover and count to thirty seconds. Pour the remaining egg over the top, cover, and immediately slide the pan off the heat. Do not lift the lid for at least two minutes. The residual heat will set the egg to a custard — the surface should dimple slightly when nudged, and the interior should move as a single mass, not slosh.

Slide everything into a bowl of hot rice. Scatter sliced spring onion over the top and serve at once. The heat from the rice and broth will finish setting the egg if needed, but if you've timed the pan correctly, you won't need it.
