Chawanmushi, also searched as Japanese savory steamed egg custard, is a gently steamed dashi-egg cup from Japan. The texture is like a smooth savory pudding hiding chicken, shrimp, and mushrooms, and it appears from family dinners to guest menus.
Ingredients
- Eggs 3 (size M)
- Dashi (katsuobushi-kombu stock) 450 ml
- Usukuchi (light-colored) soy sauce 2 tsp
- Mirin 1 tsp
- Salt just under 1/4 tsp
- Chicken thigh (skinless, small bite-size pieces) 80 g
- Peeled shrimp (or cooked shrimp) 4
- Kamaboko or narutomaki 4 slices
- Shiitake mushrooms (stems removed, thinly sliced) 2
- Mitsuba (Japanese parsley) as needed
- Yuzu zest or thin silver ankake sauce (optional) as needed
Steps
- Bring the dashi to room temperature or just lukewarm and dissolve the usukuchi soy sauce, mirin, and salt. Crack the eggs into a bowl and beat them just enough to cut through the whites (do not whip up foam). Add the dashi a little at a time while stirring. Strain through a fine-mesh sieve until the mixture is smooth. This is the chawanmushi custard base.
- Cut the chicken into bite-size pieces and season with a pinch of salt. Devein the shrimp and, if needed, blanch them briefly in salted water, then pat dry. Slice the shiitake thinly and cut the kamaboko on a diagonal. Bring water in a steamer or a deep skillet to a gentle steam over medium-low heat; the water should come about one-third to halfway up the cups so it does not boil hard against them.
- Divide the chicken, shrimp, shiitake, and kamaboko among the cups and pour in the custard gently (just enough to cover the fillings. Pop any bubbles with a skewer). Cover loosely with lids or foil and set the cups in the steaming pot.
- Steam over medium-low heat about 8 minutes. When the surface is turning white, drop to the lowest heat and steam another 7 to 10 minutes. A skewer inserted should release only clear juices. Vigorous boiling creates honeycomb holes, so if the water starts to rumble, lower the heat or crack the lid.
- Turn off the heat and let the cups sit about 2 minutes. Scatter mitsuba on top and, if you like, add yuzu zest or a thin silver ankake glaze. Serve hot.

Notes
A good weight ratio is about 1 part egg to 3 parts dashi. Hot dashi will scramble the eggs, so always cool it before mixing.
To avoid honeycomb holes, keep the heat gentle and always strain the custard. A slightly stronger start for the first few minutes, then low heat, is the usual trick.
Without a steamer, line a skillet with a cloth, set the cups on it, cover, and steam for the same times.
For an ankake glaze, thicken 100 ml dashi with 1/2 tsp each usukuchi soy sauce and mirin plus a slurry of potato starch, then spoon it over the cups.
Leftovers keep in the fridge and regain their texture if lightly restewed the next day. If you mix the custard ahead, steam it the same day.

Substitutes
- Usukuchi soy sauce → half as much dark soy plus a pinch of salt
- Chicken thigh → small chicken breast pieces / turkey
- Peeled shrimp → scallops / crab sticks
- Kamaboko or narutomaki → ginkgo nuts / quail eggs
- Mitsuba → green onion / celery leaves
Storage
Best served hot. Cool, cover, and refrigerate about 1 day; restew 3–5 minutes the next day to restore the texture. Steam mixed custard the same day. Freezing weeps liquid, so it is not recommended.
FAQ
- Why is the surface full of holes?
- The water was boiling too hard. Keep a steady steam without a rolling boil, and crack the lid or add a cloth to catch drips so fewer holes form.
- It is still watery in the center?
- Heat was too low or the cups are large. Keep steaming on the lowest heat until a skewer releases only clear juice; extra dashi also makes a softer set.
- Can I make chawanmushi ahead?
- Cut the fillings ahead and chill them. Mix the custard just before steaming. Cooked cups can be chilled and briefly restewed the next day.
- Can I use a skillet without a steamer?
- Yes. Line the pan with a cloth, set the cups in, add water one-third to halfway up the cups, cover, and use the same times.
- Can I change the fillings?
- Yes. Ginkgo nuts, quail eggs, or seasonal mushrooms are common; precook or salt any slow-cooking meat so it is done when the custard sets.
Origin and history
Chawanmushi is a classic Japanese steamed dish: beaten egg loosened with dashi, poured into tea cups, and gently steamed. The texture is like a smooth savory pudding, with hidden bites of chicken, shrimp, and mushrooms, and it appears everywhere from family dinners to formal meals.
The keys are the egg-to-dashi ratio and a long, low steam. High heat punches honeycomb holes into the custard and roughens the texture. This recipe uses the basic home ratio of about 3 parts dashi to 1 part egg and works in a steamer or a covered skillet.
Chicken, shrimp, kamaboko, and shiitake are the usual fillings, but ginkgo nuts, quail eggs, or seasonal mushrooms are equally good. It tastes fine at room temperature, so it also works as a make-ahead side.
