6 Popular Onigiri Fillings

I’ll introduce you to six popular and classic onigiri fillings and how to prepare them. These tasty variations are sure to satisfy your taste buds. Let’s go over each filling and find the perfect one for you to try!

Salmon flakes in a bottle.

Salmon

Salmon is a popular choice for onigiri. Its tender and flaky texture makes it a delightful filling. Grill a salmon fillet until it’s cooked through. Once cooled, break the salmon into flakes. For convenience, you can also use store-bought salmon flakes (picture above).

Canned tuna.

Tuna Mayo

Tuna mayo combines the rich, savory taste of tuna with the creamy texture of mayonnaise. Use water-packed canned tuna or oil-packed tuna. Drain the tuna and combine it with mayonnaise. For an authentic flavor, opt for a Japanese mayonnaise brand like Kewpie.

Umeboshi.

Umeboshi

Umeboshi, or pickled plum, is known for its unique salty and sour flavors. It pairs wonderfully with plain Japanese rice. Remove the seed from the umeboshi, and use it as it is or create a paste by chopping it with a knife.

Kombu tsukudani.

Kombu Tsukudani

Kombu tsukudani is a flavorful side dish made from kombu seaweed. It’s often enjoyed as an accompaniment to rice. You can make it by simmering the kombu with sugar, mirin, and soy sauce until it becomes tender, or use store-bought kombu tsukudani (picture above) as your filling.

Katsuobushi

Katsuobushi

Katsuobushi, or Bonito flakes, add a delightful umami flavor to your onigiri. We also call it okaka. Add soy sauce to the katsuobushi and combine it to create the filling for your onigiri.

Tarako cod row.

Tarako

Tarako, also known as salted cod roe, is prepared by marinating cod roe in a blend of salt, soy sauce, and other seasonings. The spicy tarako is called Mentaiko. Gently separate the tarako from its thin membrane or skin before using it as a filling.

Recipe Ingredients

You’ll need the following ingredients to make this recipe:

Ingredients for onigiri, rice, nori seaweed, salt and filling
  • Japanese short-grain rice: The best rice for onigiri is Japanese rice, also known as Japonica rice. It’s sticky and rich in starch, making it perfect for creating these Japanese rice balls. I recommend using Koshihikari or sushi rice for the best results. Learn how to cook Japanese rice with this recipe!
  • Nori seaweed: A type of seaweed that’s dried, crispy, and sold in sheets like the picture above. Get this full-size nori sheet (8.3”x 7.5” or 21 x 19 cm in general) at a grocery store. This size is too large for onigiri (perfect for a sushi roll, though), so we are going to divide it into 3.
  • Salt for seasoning the rice while shaping.
  • Fillings: Choose the filling from the previous section.

Recipe Tips

  • Remember to wet your hands before shaping the rice. This prevents the rice from sticking to your hands, making the process much smoother.
  • When shaping, please refrain from applying excessive force. Squeezing too firmly will yield a tight and firm onigiri, which is not the desired outcome. The goal is to get a pleasantly soft texture.
  • If you find it challenging to shape the rice with your hands, you can use plastic wrap. This makes it easier to mold the onigiri without sticking. You can also use an onigiri mold (See below).
  • Using a small bowl is convenient as it allows you to create uniformly sized onigiri every time.

What To Serve With

To complete a meal, serve it with various dishes, such as tamagoyaki, napa cabbage coleslaw, and daikon miso soup.

Storage

Onigiri is best when freshly made, but if you need to store them for later, follow these guidelines:

7 onigiri wrapped in plastic wrap
  • Wrap each onigiri tightly in plastic wrap to maintain its moisture.
  • At room temperature, onigiri can be stored for up to half a day.
  • In the fridge, they can be kept for a couple of days.
  • If you plan for longer storage, freeze them for up to one month. When freezing, avoid wrapping the nori sheet. Reheat in a microwave just before eating to prevent dryness; do not thaw at room temperature.

Your Questions Answered

What do people usually put in onigiri?

Common fillings are fish, fish eggs, pickled vegetables, and seaweed. Since the rice has a mild flavor, intensely flavorful fillings are often added.

Should Onigiri be warm or cold?

It’s fine either way. It depends on your personal preference. Since onigiri is often eaten on the go, many people eat it at room temperature. However, people who live in cold climates like Hokkaido (the northern part of Japan) are more likely to warm onigiri up before eating it.

Why won’t my onigiri stay together?

If you use long grains like Jasmine and Basmati, your onigiri would fall apart because they lack the right stickiness to hold the rice together. I recommend using Japanese rice, such as Koshihikari or sushi rice.

Is rice vinegar necessary for onigiri?

No. It’s not necessary. We use vinegar for making sushi, but not for onigiri.

Can onigiri have no filling?

Yes, you can make it without the filling. Some people prefer nothing in it, and it’s called Shio onigiri (shio means salt). It’s the simplest one made with salt, no filling, and no nori sheet!
