Oyako-donburi: Chicken, Egg and Rice in One Bowl
Season the chicken separately, bring the simmering liquid to a boil before anything goes in, and add the onion and chicken together. Confirm the chicken with a thermometer, cook the egg until no liquid remains, and finish with fresh mitsuba.
Dashi, soy sauce, sugar and mirin come to a boil in a small pot. Sliced onion and seasoned chicken thigh go in together, and beaten egg follows in a circle from the center outward. Everything then goes over white rice. Oyako-donburi (親子丼) is a rice bowl that brings together chicken and egg, the "parent" and "child" of its name, and the simmering liquid soaks into the rice with them.
The ingredient list is short, so the order matters. This article follows one specific version: a home recipe for 2 servings provided by Kondo Etsuko and published on the Tokyo page of "Uchi no Kyodo Ryori" (Our Regional Cuisines), from Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF). It uses onion and mitsuba. It isn't a restaurant formula or a single national standard, and MAFF itself notes that households differ in whether they use onion or Japanese long onion and in how firm they make the egg.

How This Version Differs from the MAFF Recipe
The ingredients, amounts and order of adding them come from MAFF. The final doneness doesn't. We changed it on purpose, so this is not a reproduction of the published method.
| Stage | MAFF recipe | This article |
|---|---|---|
| Chicken | Simmer covered for 2–3 minutes, until cooked through | Treat 2–3 minutes as a starting guide. Measure the center of the thickest piece: 75°C for at least 1 minute. If it falls short, keep cooking |
| Egg | Finish half-set: turn off the heat as the edges begin to set | Keep cooking until the whole egg is set, with no liquid left |
| Finish | Scatter mitsuba, cover and steam for 30 seconds | Turn off the heat, scatter mitsuba and serve over rice. The 30-second rest isn't used |
The 75°C for 1 minute figure is a general guideline for home cooking from Japan's Ministry of Health, Labour and Welfare (MHLW). It was not written for this dish, and MAFF's recipe doesn't state it. The set egg will be firmer than a soft, half-set finish, and we'd rather say so plainly.
We haven't kitchen-tested this adapted version, and no time in it has been safety-tested for this particular dish. Heat level, the size of the chicken pieces, the pot and the starting temperature of the food can all change how long it takes. Go by your thermometer, not the clock. Images in this article can't show temperature, time or hygiene.
Ingredients (2 Servings)
Measure the two portions of soy sauce separately. The 1/2 tsp goes on the chicken and the 1 tbsp goes in the pot.
Equipment
- Small pot with a lid
- Food thermometer with a probe
- Cutting board and knife for raw chicken
- Separate cutting board and knife for the onion and mitsuba, or the same ones washed thoroughly first
- Bowl for seasoning the chicken
- Clean bowl for the eggs
- Clean spoon for serving
- 2 rice bowls
Choosing Dashi, Rice and Eggs
Dashi: Use the dashi you normally cook with.
Rice and eggs: Use 2 servings of cooked rice and 2 eggs.
Other seasonings and toppings: This version adds no oil, long onion, shiitake, nori or shichimi, and we don't offer a substitute for the chicken.
Allergies: Labels on soy sauce and dashi products vary, so check the ones you buy.
Method: Season, Boil, Measure, Set
Wash your hands after handling raw chicken or raw egg. Wash any tool that touched raw chicken before using it for other food. If you have to stop partway through cooking, refrigerate the food rather than leaving it at room temperature, and heat it thoroughly when you resume.
Serving
Serve the bowls hot, and don't leave the cooked food sitting out at room temperature.
Troubleshooting
| What you notice | Possible reason | What to do |
|---|---|---|
| The chicken is below 75°C after 2–3 minutes | Heat level, piece size or the pot | Keep cooking and measure again. The thermometer takes priority over the time |
| Some pieces cook faster than others | Pieces are large or uneven | Keep cooking until the thickest piece passes, and cut bite-size angled slices next time |
| The seasoning seems off | The 1/2 tsp and 1 tbsp portions of soy sauce were mixed up or combined | Keep the two measures separate next time |
| Some egg is still liquid | The heat went off too early | Turn the heat back on and cook until no liquid remains, before adding the mitsuba if you can |
| The egg is firmer than you expected | This version sets the egg fully | That's expected here. Don't shorten the cooking to get a softer egg |
| You have to stop partway through | Anything that interrupts the cooking | Refrigerate the food instead of leaving it out, and heat it thoroughly when you resume |
Ways Oyako-donburi Varies
These are differences you may come across, not tested versions of this recipe. We give no amounts because we have none we can support.
- Long onion instead of onion: MAFF notes that households differ here, but this recipe doesn't set an amount for long onion.
- Other herbs: Mitsuba is the herb used here. We have no sourced herb or amount to suggest in its place.
- Individual pans: Ajinomoto Park publishes a separate 2-serving recipe in which half the mixture at a time is finished in a one-portion pan. It uses 150g chicken thigh, 100g onion, 3/4 cup water, 1 1/2 tbsp each of mirin and soy sauce, 1/3 tsp dashi seasoning, 2 eggs and 440g rice. It's a useful comparison, but its balance is different, so don't mix its amounts with the ones above.
- Different dashi: Comparing kinds of dashi would need separate research.
- Egg firmness: MAFF says this varies between households. This article sets the egg fully and doesn't cover a half-set method.
Background: Oyako-ni and the Origin Story MAFF Presents
MAFF's Tokyo page traces the dish to Tamahide. Around the 20th year of the Meiji era, chicken and warishita sauce bound with egg were eaten there as the close of a chicken sukiyaki meal, and this was called oyako-ni. In the 24th year of Meiji, Toku, the wife of the fifth-generation head, put it over rice and made it a dish of its own. MAFF presents this as the point where oyako-donburi is said to have begun.
We pass this on as the account MAFF gives, not as the single settled origin of the dish. We also haven't compared restaurant formulas or looked at how Tamahide serves the dish today, so this home recipe shouldn't be read as a restaurant's version.
Frequently Asked Questions
Where did oyako-donburi come from?
MAFF's Tokyo page says it is said to have begun with oyako-ni at Tamahide, served over rice in the 24th year of Meiji. We treat that as an attributed account, not as the only possible origin.
How long should I simmer the chicken?
MAFF's recipe gives 2–3 minutes, until the chicken is cooked through. In this article that's only a starting guide. Check that the center of the thickest piece stays at 75°C for at least 1 minute, and keep cooking if it doesn't. That figure is MHLW's general guideline for home cooking, not a time tested for this dish.
Can I leave the egg half-set?
Not in this recipe. MAFF's method finishes the egg half-set, but we changed it for home food safety, so the egg cooks until no liquid remains. We don't cover half-set or raw-egg versions.
Why wash the mitsuba if the rest is cooked?
The mitsuba goes on fresh after the heat is off, so it gets no cooking step in this method. Washing it under running water and keeping it away from raw-chicken tools is our own editorial addition, not an instruction from MAFF or MHLW.
Which dashi should I use, and how much rice is 2 servings?
MAFF's recipe doesn't name a kind of dashi or give a weight for the rice, so we don't add either. Ajinomoto Park's separate recipe uses 440g of rice, but that belongs to its own balance of ingredients.
Can I store leftovers?
We have no storage period to give, because our references don't set one for this dish. MHLW's general advice is not to leave cooked food at room temperature. If cooking is interrupted, refrigerate the food and heat it thoroughly when you resume.
