Oyakodon is a Japanese one bowl rice dish. Steamed white rice is topped with a combination of onions, chicken and softly cooked eggs that's been simmered in a broth of dashi, sake, mirin and soy sauce.
Heat a frying pan over medium high heat and pour in the dashi, soy sauce, mirin and sake and bring to a gentle boil.
Add the onions and cook for about a minute.
Add the chicken, stir and simmer on low heat, uncovered, until the chicken is cooked, about 5-10 minutes, depending on the size of your chicken.
Pour the beaten egg all over the chicken, don't stir, cook it, covered for 1-2 minutes, until the egg is set. I prefer mine a little on the runny side still. If you want a fully cooked egg, go for 1 more minute.
Fluff up the rice and dish it up into a bowl.
Tip the chicken and egg mix onto your rice, top with spring onions and serve immediately. Sprinkle with some togarashi schichimi or crushed nori, if you like.
Notes
If you don't do alcohol, leave out the sake and mirin and use a total of 1 tsp clear vinegar or rice vinegar, plus 1/2 tsp white sugar and 2 tsp water.
