10 Triangle kimbap and Onigiri Fillings

For this ‘Emily Recommends’ series, we will take a look at different triangle kimap and onigiri fillings. If you want to check out past series posts, look at our 15 Korean Street Food Recipes and our 10 Rice Bowl Recipes.

Onigiri, also known as omusubi or rice balls, is a Japanese simple meal made from white short-grained rice formed into a triangular shape. Often, it is then wrapped in nori (the Japanese word for seaweed). 

On the other hand, triangle kimbap is the South Korean equivalent made using a mold to shape fillings and rice into a triangle which is then wrapped in kim (the Korean word for seaweed). The Korean version is based on Japanese onigiri which was introduced to South Korea in the 1990s. 

While the basic premise is the same, the fillings are very different and lean on the typical flavors of each culture. In this week’s ‘Emily Recommends’ series, we decided to introduce some different triangle kimbap and onigiri fillings! 

Onigiri Fillings

First, before we start, if you want to learn how to make and form a rice ball, I recommend checking out the blog No Recipes. Marc, the author, has an in-depth explanation of how to mold the rice and recommendations for a few different onigiri fillings. 

1. Sake Onigiri

The sake version of rice balls usually refers to onigiri with a particular style of salmon prepared with salt and Japanese sake. The word for this style of salted salmon is ‘shiozake’ or ‘shiojake’. In Japan, they eat shiozake on its own as a filet or mixed with other ingredients to make another dish such as fried rice or rice porridge. 

Sake onigiri happens to be one of the most popular versions available in Japan. The salty and fishy flavor of the salmon acts as one of the most perfect onigiri fillings. The Japanese typically crumple up the shiozake salmon into little pieces and add them to the rice. Once added, they form the mixture into a rice ball shape. 

Shihoko, who runs the blog Chopstick Chronicles, has a wonderful recipe. You can find her recipes for shiozake and sake onigiri via the links below. Also, we added a link to the home page of her website.

2. Miso Yaki Onigiri 

Yaki onigiri refers to rice balls that are grilled. Yaki means ‘grilled’ in Japanese. While there are many different types of yaki onigiri, the miso version is a favorite amongst the Japanese population! 

For those outside of Japan, miso seems to be well known because of miso soup in Japanese and sushi restaurants. In Japan, the use of miso expands much further than just soup. Proof is with these miso yaki onigiri’s. 

While many onigiri have the extra ‘special’ flavoring added into the rice as a filling, the miso flavoring is added on the outside of the yaki onigiri to add a caramelized flavor. To make miso yaki onigiri, you must brush the miso mixture onto the rice ball before grilling in a pan.

In the end, we recommend looking at Nami’s recipe from her blog Just One Cookbook! She gives detailed step-by-step instructions on how to prepare the rice ball and the miso! Finally, you can find her recipe and website via the links below! 


3. Mentaiko Mayo Yaki Onigiri

Mentaiko refers to Japanese marinated pollock or cod roe. Typically, you can find mentaiko in the refrigerator or freezer at an Asian grocery store (H-mart is a good example). To prepare mentaiko, you must remove the roe from the protective skin. Then, you can combine the mayonnaise with the roe to make a delicious paste! 

Once again, the Chopstick Chronicles has a delicious version of this onigiri. Mentaiko Mayo makes a uniquely flavored yaki onigiri. We hope you enjoy this style of onigiri filling! Lastly, we linked the recipe below.

4. Plum Onigiri

Probably one of the most popular and traditional onigiri fillings in Japan would be pickled plum. 

The word for pickled plum in Japanese is umeboshi. In Japan, umeboshi is a traditional condiment often eaten with a bowl of rice. 

When making onigiri, the Japanese often chop up the umeboshi and add it into the rice. Once added, they form triangular rice ball shapes with their hands before serving to eat. Onigiri tastes the best when eaten on a picnic. Who wouldn’t you want to eat a perfectly shaped plum onigiri on a nice spring day?! 

You can find a recipe for plum onigiri on Nami’s website Just One Cookbook. Finally, find the links below!   


5. Tenmusu Onigiri

When the Japanese say ‘tenmusu’, they are using a shorthand word for a rice ball with deep-fried shrimp tempura as the filling. The word tenmusu comes from two words: ‘tempura’ and ‘omusubi’. The tempura refers to the deep-fried shrimp while the omusubi refers to the rice ball. 

For this type of onigiri, you start by frying battered shrimp. Once you fry the shrimp in oil and let it slightly cool, you place it inside the rice and form it into a ball. Typically, you place seaweed around the rice for this type of onigiri. 

We recommend checking out Nami’s recipe from her blog Just One Cookbook for this recipe. You can find the links for her website and recipe below! 


Do You Have Favorite Onigiri Fillings?

We hope you enjoyed the list of onigiri fillings we offered above! In the end, do you have a favorite?

Next, let’s look at different Korean triangle kimbap fillings! 

Triangle Kimbap Fillings

Like we stated above, triangle kimbap developed from Japanese onigiri. Even so, much of their triangle kimbap fillings come from pre-existing Korean flavors and dishes they had already developed. Let’s look at some typical Korean triangle kimbap fillings!  

6. Tuna Kimchi Triangle Kimbap (Chamchi) 

Online and in South Korea, tuna kimchi triangle kimbap probably rules as the most common version available. Koreans readily use both ingredients in much of their cooking. For example, check out Korean tuna mayo rice for a quick tuna based Korean lunch!

To make the filling, you fry up equal parts kimchi with canned tuna. Really, it is that simple! If your kimchi is too sour, add a bit of sugar. If the kimchi doesn’t have enough spice, add a bit of gochugaru. Finally, you can find our recipe and triangle kimbap instructions via the link below!

7. Spicy Pork Stir Fry Filling

The Korean population often enjoys a spicy kick to their food–triangle kimbap is no exception. Spicy flavors are very unique to Korean rice balls as the Japanese do not often enjoy extreme spice levels in their food. 

For this recipe, I recommend checking out the Youtube channel Aeri’s Kitchen. She gives you step-by-step video instructions on how to make the triangle kimbap filling and how to shape the kimbap! Follow the recipe here!


8. Tuna Mayo Filling 

While Koreans enjoy tuna mixed with kimchi for triangle kimbap, they also enjoy tuna mixed with mayonnaise. This version of triangle kimbap tastes the most similar with certain flavors of Japanese onigiri! 

Like the tuna kimchi triangle kimbap, tuna mayo takes very little effort or time to make. You just need to add some canned tuna together with some mayonnaise! Depending on your preferences, you can also add some salt, pepper, and/or sugar! 

In this case, we recommend checking out JinJoo’s recipe on her blog Kimchimari. For her blog post, she actually has a few different fillings you can try out! Also, she made hers without the dried seaweed exterior. So, if you want the dried seaweed, you can look at our post to learn how to fold the seaweed.

9. Bulgogi Filling

In Korea, bulgogi is also a very popular filling. Typically, when making kimbap at home, people use leftover bulgogi from a past meal. They do not make bulgogi just for traditional or triangle kimbap. 

We recommend trying to make bulgogi for dinner and then use the leftovers as fillings for your triangle kimbap! When adding bulgogi to triangle kimbap, remember to remove any excess liquid. Your triangle kimbap may fall apart if you have any liquid from the bulgogi. 

In this case, we recommend checking out Sue’s bulgogi recipe from My Korean Kitchen. Once made, you can easily add it to your triangle kimbap. Finally, learn how to fold triangle kimbap via our post!

10. Spam 

Koreans also enjoy adding spam to their triangle kimbap. In this case, you do not need a recipe because it is so simple! Start by slicing spam into thin pieces. Then, pan fry the spam until both sides get golden brown. Finally, chop the spam up into tiny pieces.

You then add the spam onto the center of your rice and form your triangle kimbap. This version takes very little time to make and acts as the perfect meal to eat while at your desk. For a further variation, fry up some minced kimchi with the spam! 

Do You Have a Favorite Triangle Kimbap Filling? 

Triangle kimbap typically uses simple and cheap ingredients. These meal replacements can be found at convenience stores all across South Korea! Do you have a favorite filling?
