What is Oshiruko?

Oshiruko is a traditional Japanese dessert soup and is popular during the colder seasons in Japan.

The sweet red bean soup is made from anko (red bean paste) to create a smooth broth, and the chewy mochi cakes are added to the soup just before serving.

📋 Ingredients

Here are the ingredients (amounts are in the recipe card below).

Ingredients for oshiruko.
  • Mochi – Japanese rice cake made from glutinous rice. I use store-bought kiri mochi in this recipe. See more details below.
  • Anko – Sweet red bean paste made from azuki beans. Essential ingredients for Japanese pastry. See more details below.
  • Salt


kiri mochi

Mochi is a traditional Japanese food made from glutinous rice with a gooey and chewy texture. The mochi itself is not sweetened, which makes it a versatile ingredient that can be used in both sweet and savory dishes.

Kiri mochi is a type of mochi pre-cut into rectangular shapes; it’s dried, hard like bar soap, and comes in individual packages. It’s convenient and easy to portion out and use in various recipes.

If you are trying a mochi recipe for the first time, I highly recommend kiri mochi. This Sato no kiri mochi is a famous brand and is pre-cut with a slit, which makes it easier to break apart by hand and cook evenly.

*Mochi should be enjoyed with caution as a potential choking hazard, especially for the elderly and small children. Cut the mochi into small pieces and chew very well when eating.


anko paste

Anko is a sweet paste made from small red beans called azuki. It’s used for traditional Japanese confectioneries such as daifuku mochi, dorayaki, and manjū.

The anko paste is made by boiling the azuki beans until they are soft, then sweetening them with sugar. The resulting paste is sweet with a slightly grainy texture due to the mashed beans.

There are two types of anko commonly used in Japanese cuisine:

  1. Koshian – smooth red bean paste made by mashing cooked azuki beans through a sieve to create a smooth paste.
  2. Tsubuan – chunky red bean paste made without passing it through a sieve.

This recipe calls for Tsubuan as I prefer its chunky texture, but this is based on personal preference, and you can use either one.

Helpful tips

  • You can adjust the sweetness and thickness of the soup to your liking by adding more or less water.
  • There are a lot of different ways to cook mochi. See the other options below.

Various Ways To Cook Mochi

A nonstick pan is a convenient way to cook mochi, but there are several other methods to grill or cook mochi, such as:

  1. Grill – Grilling the mochi on a barbecue or stovetop grill pan is a traditional method. The mochi can be placed on the grill and cooked until it becomes crispy and golden brown.
  2. Oven – The mochi can be baked in the oven by placing it on a baking sheet and baking it until it is golden brown and crispy. This method is excellent if you want to make a large batch of mochi.
  3. Toaster oven – A toaster oven is a quick and easy way to cook small batches of mochi. Place the mochi in the toaster oven and cook until it is crispy and golden brown.
  4. Microwave – The mochi can also be cooked in the microwave by placing it on a plate with a little water and microwaving it until it becomes soft. The mochi texture is different, but this method is time-saving as it takes only a few minutes and requires minimal effort.

How to eat it

Use chopsticks or a spoon to pick up a piece of mochi from the soup. Dip the mochi into the soup and let it absorb some of the sweet broth. And take a small bite of the mochi, enjoying its chewy texture and the soup’s sweetness.
