When you are feeling under the weather, on a cool evening, or after a hot pot meal, zosui is the comforting Japanese rice porridge that has warmed tables for generations.
This article covers the basic zosui recipe, tips for getting it right every time, and easy variations you can make with ingredients available in Ho Chi Minh City.
1. What is Zosui: Difference from Ojiya
Zosui is a traditional Japanese dish of cooked rice simmered in dashi broth. It is gentle on the stomach and easy to eat even when you have no appetite or are recovering from a cold.
A similar dish, ojiya, is often confused with zosui. The general distinction is:
- Zosui: rice is rinsed to remove surface starch before simmering in dashi. Results in a lighter, less thick porridge
- Ojiya: rice goes straight into the dashi without rinsing. Results in a thicker, starchier porridge
Every household makes it a little differently, so do not worry too much about definitions — just cook it the way you enjoy.
2. Basic Zosui Recipe
2-1. Ingredients (serves 2)
- Cooked rice: 2 bowls (leftover rice works great)
- Eggs: 2
- Dashi stock: 600ml (katsuobushi dashi or 1 tsp granule dashi dissolved in water)
- Soy sauce: 1 tablespoon
- Salt: a pinch
- Green onions: to taste (thinly sliced)
2-2. Steps
- Place the cold rice in a colander and quickly rinse under cold water to remove surface starch
- Bring the dashi to a simmer over medium heat, then season with soy sauce and salt
- Add the rinsed rice, bring back to a simmer, reduce heat and cook for 2–3 minutes
- Drizzle the beaten egg in a thin stream, cover and let it set for about 30 seconds
- Ladle into bowls and top with green onions
2-3. Tips for Success
- Rinse the rice: removing excess starch gives zosui its characteristic light texture
- Add egg just before finishing: letting residual heat cook the egg gives it a soft, fluffy consistency
- Use slightly more dashi than you think you need: the rice absorbs liquid as it cooks
3. Zosui Variations
3-1. Chicken Zosui
Cut chicken thigh into bite-sized pieces and simmer in dashi first before adding the rice. The umami from the chicken enriches the broth. A garnish of mitsuba leaves or yuzu zest adds a lovely fragrance.
3-2. Umeboshi Zosui
Add 1–2 pickled plums (umeboshi) to a simple egg zosui. The tartness stimulates the appetite and makes it especially easy to eat when you are unwell.
3-3. Kimchi Zosui
Stir-fry pork and kimchi in sesame oil, then add dashi and rice. The spicy kick surprisingly works well even on hot days in Ho Chi Minh City. A sprinkle of melted cheese at the end is also a great addition.

FAQ
Q. Should I use freshly cooked or leftover rice for zosui? A. Leftover cold rice is better. Once chilled, rice has less surface starch, rinses more easily, and produces a cleaner, lighter porridge.
Q. What can I use if I do not have dashi? A. Chicken broth or shiro-dashi (white dashi) work as substitutes. They have different salt levels, so add gradually and taste as you go.
Q. Can I make zosui ahead of time? A. It is not ideal — the rice continues to absorb liquid and becomes mushy. Zosui tastes best made fresh just before eating.
Q. Can young children eat it? A. Yes. Simply season more lightly and chop the ingredients finely for younger children.

Zosui is a Japanese home-cooking staple that comes together with minimal ingredients. Once you have the basic egg zosui down, the variations — chicken, umeboshi, kimchi — are easy to explore.
