With savory Korean grilled beef and steamed rice wrapped in nori seaweed, this ultimate Bulgogi Onigirazu makes for a perfect summer lunch or picnic! For a more substantial wrap, add optional fried egg and vegetables like seasoned bean sprouts, spinach, carrots, and shiitake mushrooms.

If you are aware or have heard of Onigirazu (おにぎらず) – a type of Japanese rice ball, then you’re pretty current with the latest of Japanese food trends!
Onigirazu was in fact one of the most influential food trends in Japan last year (2015) and today I’m making Onigirazu with Bulgogi, Korean grilled beef!

What is Onigirazu?
The name Onigirazu comes from the Japanese rice ball – Onigiri (おにぎり) or sometimes called Omusubi (おむすび).

Onigiri is a great healthy choice for lunch or snacks. It is made of rice formed into the traditional triangle, round, or cylinder shape with hands. Usually, the rice ball is filled with pickled plum (umemboshi), soy sauce seasoned bonito flakes (okaka), or other kinds of fillings, and then wrapped with nori seaweed.
The word “Onigiri” comes from “Nigiru“, which means to squeeze or hold tightly in Japanese. When you do NOT squeeze tightly, we say “Nigiranai” or “Nigirazu“.
So Onigirazu is the rice ball (Onigiri) that is NOT squeezed tightly into the traditional shape (Nigirazu).

The Onigirazu History
Although Onigirazu became a huge trend last year, it had been introduced 25 years ago by manga artist Tochi Ueyama in his manga (Japanese comic books) “Cooking Papa“.
In his food manga, the main character, a dad and salary-man, likes to cook for his family. Ueyama named this dish “Onigirazu” and introduced it in his comic books when he saw his wife making a new style of Onigiri.
In fall 2014, the most popular Japanese recipe-sharing site, Cookpad, had a feature on Onigirazu recipes. Since then, this recipe was revived and it became a popular search word, especially among housewives who make their husband’s and children’s lunches.

3 Reasons Why You Should Make Onigirazu
It has 3 big appealing features that caught everyone’s attention and stayed popular.
1. More fillings; make it into a meal!
It can be stuffed with much more fillings than Onigiri.
Onigiri tends to include one kind of filing, but Onigirazu usually has more than 2-3 kinds of fillings! With a main dish filling like Bulgogi and Tonkatsu, you can get carb (rice), protein (meat), and veggies (lettuce) in one bite!
2. No more mess; easy to assemble!
When you make this delicious dish, you wrap the rice with nori sheet. Therefore, you don’t have to wet your hands and form rice into a rice ball. While Onigiri takes practice and some skill to make, Onigirazu is very simple to assemble, just like a sandwich!
3. Endless creative fillings!
Most people stick with traditional filling when it comes to Onigiri because of limited filling space. However, people are very creative and put unconventional fillings in Onigirazu like ham, cheese, egg, fried chicken, and grilled meat.
Onigirazu also uses various condiments like ketchup, Tonkatsu sauce, and mayonnaise for spreads which is not common for Onigiri.

5 Tips to Make Perfect Onigirazu
Tip 1. Spread the rice into a square shape

Place a nori sheet with a corner pointing up. Try to evenly spread the rice into a square shape in the center of nori. Don’t forget to leave some space around the rice for easy wrapping.
Tip 2. Put the rice and fillings in a thin layer

Make sure to place the fillings in single/thin layers and stack them on top of previous one, avoid empty spaces. When you place ingredients, think about the cross-section view after you cut in half. Work with small amount of fillings so that it’s easier to wrap.
Tip 3. Mark which side you would cut in half

If your fillings are placed in a single layer on top of another, you don’t need to worry about this tip (like lettuce, cheese, ham etc).
If you place multiple ingredients, it’s important to remember which side you’d need to cut in half before you finish wrapping with nori (and can’t see inside!).
In above diagram, we need to cut along the pink line so that all the fillings with different colors will be visible from cross-section. A trick to remember? Mark the cutting line with a piece of ingredient (I used a stick of carrot).
Tip 4. Flip and rest for 5 minutes
Fold each corner of nori sheet tightly around the layers of rice and fillings at the center. Wrap tightly with plastic wrap and flip over, seam side down. The steam from the rice will moisten nori sheet and bind all the ingredients well together.
Tip 5. Wet your sharp knife
Use a sharp knife to cut it in half. If you run water on your knife before cutting in half, the rice and nori won’t stick to your knife and the cross-section will be clean.

Our Family’s Favorite Bulgogi Recipe
My family loves this Bulgogi recipe that I had been cooking… but I had been using Japanese soy sauce. It tastes great, but I had never imagined it could taste even better with Korean soy sauce!
When I did this last collaboration video with Seonkyoung, she gave me a bottle of Korean soy sauce. I should have bought a bottle of Korean soy sauce years ago for Korean dishes! Korean dishes taste FANTASTIC with Korean soy sauce (duh?!). Keep your Japanese soy sauce for Japanese recipes, and I highly recommend using Korean soy sauce for this recipe!
To add more colors to this Bulgogi Onigirazu, I added vegetable side dishes that I use for my Bibimbap recipe. It definitely requires a bit of extra work, so you can totally skip these veggies. However, cross-section looks pretty when green and red colors pop out, and not to mention yellow fried egg!
The gochujang sauce in the recipe is optional too, but we love this spicy and sweet savory sauce for my Bibimbap recipe…so again I use this sauce for this recipe. Bulgogi Onigirazu tastes perfect without the gochujang sauce.

- ½ carrot
- 3 green onions/scallions
- 1 lb beef (tenderloin, ribeye, or top sirloin)
- 1 Tbsp toasted sesame oil (for cooking the meat)
- 1 Tbsp toasted white sesame seeds (for topping)
For the Bean Sprouts (optional)
- 1 Tbsp toasted sesame oil
- 1 clove garlic (½ tsp minced)
- ½ tsp Diamond Crystal kosher salt (for the dressing)
- 1 tsp Diamond Crystal kosher salt (for blanching)
- 6 oz bean sprouts (½ package)
- 1 green onion/scallion
For the Spinach (optional)
- 1 Tbsp toasted sesame oil
- 1 clove garlic (½ tsp minced)
- ½ tsp Diamond Crystal kosher salt
- ½ bunch spinach
For the Carrot (optional)
- ½ large carrot
- 1 tsp toasted sesame oil
- ⅛ tsp Diamond Crystal kosher salt
For the Shiitake Mushrooms (optional)
For the Eggs (optional)
- 1 Tbsp neutral oil
- 4 large eggs (50 g each w/o shell)
For Making the Onigirazu
- 4 servings cooked Japanese short-grain rice (4 cups, 600 g)
- 4 sheets nori (dried laver seaweed)
- Diamond Crystal kosher salt (for sprinkling on the rice)
For the Gochujang Sauce (optional)
- 2 Tbsp gochujang (Korean chili paste)
- 1 Tbsp toasted sesame oil
- 1 Tbsp sugar
- 1 Tbsp toasted white sesame seeds
- 1–2 Tbsp water (to dilute to your desired consistency)
Instructions
- Before You Start: Gather all the ingredients. For the steamed rice, please note that 1½ cups (300 g, 2 rice cooker cups) of uncooked Japanese short-grain rice yield 4⅓ cups (660 g) of cooked white rice. See how to cook short-grain rice with a rice cooker, pot over the stove, Instant Pot, or donabe.
To Make the Bulgogi Marinade
- In a large bowl, combine the ingredients for the bulgogi marinade: 1 Tbsp toasted sesame oil, 2 Tbsp Korean soy sauce, 2 Tbsp brown sugar, and freshly ground black pepper. Grate ¼ Asian pear, measure 2 Tbsp grated pear, and add to the bowl. Crush (or mince) 4 cloves garlic, measure 2 tsp minced garlic, and add to the bowl. Mix it all together.
- Cut ½ onion into thin slices. Cut ½ carrot to 2-inch (5-cm) pieces, then cut into julienned pieces.
- Cut 3 green onions/scallions into 2-inch (5-cm) pieces. Cut 1 lb beef into thin 2-inch (5-cm) strips. Tip: I put the meat in the freezer for 2 hours (depending on the size and thickness) prior to cutting the meat into thin slices. See my tutorial on how I slice my meat.
- Add the vegetables and meat to the bowl and toss to coat with the marinade. Set aside for at least 20 minutes.
To Prepare the Bean Sprouts and Spinach (optional)
- Prepare 2 medium bowls. In each bowl, combine 1 Tbsp toasted sesame oil, ½ tsp minced garlic (from 1 clove garlic), and ½ tsp Diamond Crystal kosher salt and mix well.
- Bring a medium pot of water to a boil and add 1 tsp Diamond Crystal kosher salt. Add 6 oz bean sprouts and cook for about 1 minute. We will need to reserve the boiling water for spinach, so scoop up the bean sprouts with a sieve or spider strainer. Run under cold tap water to stop the cooking further with remaining heat and drain well. Set aside.
- Prepare iced water in a large bowl. In the same boiling water, blanch ½ bunch spinach for 30 seconds. Transfer the spinach to the iced water to stop the cooking.
- Squeeze out the water from spinach as much as you can and add to one of the bowls with the seasonings. Toss well with the sauce.
- Thinly cut 1 green onion/scallion. Add the bean sprouts and green onion to the other bowl and toss well with the sauce.
For the Carrot and Shiitake Mushrooms (optional)
- Cut ½ large carrot in half widthwise, about 2 inches (5 cm) long. Cut each piece into thin slices, and julienne the carrots. Cut 6 shiitake mushrooms into thin slices.
- Heat 1 tsp toasted sesame oil in a large frying pan and add the carrot. Season with ⅛ tsp Diamond Crystal kosher salt and sauté until tender. If your pan is big enough to add the shiitake mushrooms, move the carrot to one side when it’s cooked halfway. Add 1 tsp toasted sesame oil in the open space and add the shiitake mushrooms. Season with ⅛ tsp Diamond Crystal kosher salt and sauté until tender. If your frying pan is small, cook one ingredient at a time; transfer the carrot to a plate and cook the shiitake mushrooms after. When the carrot and shiitake mushrooms are both tender (but not overcooked), transfer to a plate and set aside.
To Cook the Eggs (optional)
- Heat 1 Tbsp neutral oil in the large frying pan and make fried eggs with 4 large eggs (50 g each w/o shell). I cook the eggs “over hard” so the egg yolk won’t be runny and messy when the onigirazu is cut in half.
To Grill the Meat
- In a large skillet (I use a griddle pan so I can grill the meat in a single layer), heat 1 Tbsp toasted sesame oil over medium-high heat and sauté the marinated beef until cooked, about 5 minutes. Transfer the meat to the plate and sprinkle with 1 Tbsp toasted white sesame seeds.
To Make the Gochujang Sauce (optional)
- In a small bowl, combine all of the sauce ingredients: 2 Tbsp gochujang (Korean chili paste), 1 Tbsp toasted sesame oil, 1 Tbsp sugar, and 1 Tbsp toasted white sesame seeds. Mix them all together. Add 1–2 Tbsp water until you achieve the consistency you like.
To Assemble the Onigirazu
- Place a piece of plastic wrap on a working surface and put a sheet of nori seaweed on top (shiny side down), with a corner pointing up. Evenly spread ½ serving of the steamed rice in a thin layer and form into a square shape in the center of the nori sheet. If you make the onigirazu with different ingredients that have a milder taste, sprinkling Diamond Crystal kosher salt at this step is very important, especially if you plan on eating it at room temperature.
- Place one serving of bulgogi on top of the rice in a thin layer. Then, put one serving of spinach, bean sprouts, carrot, and shiitake in a thin layer on top of the meat.
- Add the fried egg. Then, add another ½ serving of steamed rice on top. Try to keep the square shape as you spread the rice evenly in a thin layer.
- Bring the left and right corners of nori sheet towards the center. Fold gently but tightly to wrap around the layers at the center.
- Then, bring the bottom and top corners towards the center. Continue to fold gently but tightly around the layers. Make sure the rice is tucked in nicely. If you‘d like the onigirazu to showcase the ingredients after cutting it in half, mark it with a piece of carrot perpendicular to the ingredients (see video). Flip over and shape the onigirazu gently. Wrap tightly with the plastic wrap and set aside for 5 minutes. Repeat assembling the remaining onigirazu.
- Cut the onigirazu with a sharp knife (following your “carrot” mark). Run your knife in cold water before cutting so that the cross section will be clean. The Bulgogi Onigirazu is now ready to enjoy.
To Store
- If you plan to make it ahead of time, wrap the onigirazu with a kitchen towel and keep in the refrigerator overnight. The towel will prevent the rice from getting harder from cold air.
This is insanely good! I’ve been following your blog and making your recipes for a while now, but I think this is my first time to comment. I absolutely LOVE this recipe. I have to admit, in the cooking storm I whipped up (preparing agedashi tofu alongside this) I forgot to fry some eggs to put in, but no matter, it was still delicious and I stuffed it so full I would have struggled to close the pouches if I had added an egg.
I made a couple minor departures from your recipe. I didn’t use the shiitakes, and because I can’t eat very spicy foods, I substituted the chili paste in the gochujang sauce recipe with hoisin sauce just to help give it some thickness, and I added just a touch of sriracha to give it just a little spiciness. The result was a much sweeter and less spicier sauce than intended, and may not be the most authentic addition to these predominantly korean flavors, but it tasted great and worked for me!
I LOVE Onigirazu! Thank you for introducing them to me! I have to say I have always been rather picky about bread and sandwiches, but this seems like an awesome and healthy way to make them, and with so many more possible ingredients since I think many things (like cooked veggies) taste good on rice than they would on bread. I can understand why these would become a food craze in Japan. They’re simple, pretty, and delicious, and easily put into a bento. I think I have found a new staple food for my ever-evolving diet. I tried hitomebore rice for the first time (on this very recipe) and it is wonderful!
Hi Lion! Thank you so much for reading my blog and trying out my recipes! I appreciate that you took time to leave a kind feedback here. Thank you!!
I’m happy to hear you liked this recipe. I love this Bulgogi recipe. It’s the one I’ve been using for some time now. I’m glad you adapted the recipe and it worked out well.
My kids love Onigirazu too, so I often make it for my family. I love that I don’t have to worry about how I pack enough vegetables and ingredients in their lunch as Onigirazu can fit so many fillings inside.
Thank you again for your kind comment! xo
Hi,
How do you store extra Onigirazu? Would you put it in the fridge or leave them out on the counter?
Thanks!
Jen
Hi Jennifer! It’s up to where you live. If you live in a relatively cool/cold place, you can leave it out overnight for you to enjoy after overnight. But if you live in a warm place, I definitely recommend to put in the refrigerator. It also depends on the filling too. It might requires refrigeration, then keep in the fridge to be safe.
If you put in the fridge directly, your onigirazu will be harder because rice gets hard in the fridge (even wrapped with plastic wrap). So my recommendation is to wrap around with kitchen towel to create a cooler environment for Onigirazu, not cold environment. That way, food is safe, and rice won’t be too hard. Hope this helps! 🙂
Thank you! This helps out a lot!
Hi, Nami! I just found your bulgogi onigarazu recipe and am excited to try it. I had a question. I want to make this for my husband’s lunch and I was wondering if the assembled onigarazu’s rice would remain nice and fluffy from one day to the next in the fridge. I had some not so great day old California rolls a while ago, and the rice just wasn’t the same. Is this something that must be made and eaten the same day or can it be enjoyed the next day? Thanks so much!
Hi Audrey! Nothing beats than freshly made (or in this case, a couple of hours at least). But I think it’s okay with me. I’m not sure how particular you are about the rice condition, but if you uses Japanese rice (type of rice matters) and cooked properly, it should be okay. I always recommend to cover the rice balls and Onigirazu with kitchen towel when you store in the fridge so that they don’t become hard from cold air. Kitchen towel will keep the rice balls or onigirazu cool enough for food safety but not harden. So make sure to control that. Some people mentioned about nori. Nori will be wilted when you get onigirazu (because you have to “wrap” the rice sandwich). Some nori might be too chewy when it’s wilted. If you only like crispy nori, that’s one thing you might consider. I recommend get good quality nori which shouldn’t be too bad. Hope I answered your question. 🙂
What if I want it for lunch time the next day?
Hi Neva! Do you mean you cook it on previous day? You can make ahead of time and keep it in the refrigerator. However rice tends to get hard, so my recommendation is to wrap it around with kitchen towel so that onigirazu won’t get too cold (=too hard). 🙂 Hope this help!
Hi! I am so excited to have found your website! I adore Japanese cuisine and you do such a wonderful job of explaining how to do things!
I have a few questions about this recipe. I am not a huge fan of most Nori, what I get here in the states is very “fishy” tasting (that’s the only way I know how to describe it, I’m sorry). Would this recipe work if I were to use one of the pink soy wrappers(like for sushi)? If the soy wrapper will not work is there a specific nori I should look for that may have a more mild taste? I am so excited to try this as bulgogi is a huge fan favorite in our household!
Thank you so much!
Hi Rhea! Welcome to my site! I’ve never had a chance to try soy wrappers so I can’t say for sure, but I am hoping it would work. Since it’s used for sushi, I assume it’s easy to cut and hold the rice together… I would say why not? Unfortunately, nori we can get in the US is such a low quality that it’s gummy and tastes is below average quality we can buy in Japan. I don’t know why… so if you really want to give it a try, I recommend getting the most expensive nori in the Japanese market and see if you like it. It should taste better than what you have tried, I think. 🙂
I did it!
And it turned out beutiful and deliciouss!
Definetly doing it again!!
Thank u!
Really easy steps!

Greetings from Hungary:
Judy and Patrick
Hi Judy and Patrick! Thank you so much for sharing the picture with me! Wow looks so delicious! Thanks so much for trying the onigirazu recipe! Arigato for trying out my recipes! SO happy to know I have awesome readers in Hungary! xoxo
I just watched this video and it made my mouth watered! Your videos are invaluable because you not only teach us how to make it but you also show us how to cut the ingredients! I also love these fusion Korean-Japanese recipes! Keep up the great work, Nami!
Hi Ker-Yng! I’m so happy to hear you enjoy my videos and thanks for your kind feedback! 🙂 And thank you for your support all the time! xo
I made this for the first time and my entire family loved it!
Hi Kayla! I’m so happy to hear your family enjoyed it! Thanks so much for your kind feedback! 🙂
Hi do you need to wait for the rice and ingredients to cool down before wrapping?
Hi Cheng! No, for Onigirazu, it’s key to use hot ingredients (at least rice) so that nori will get wilted easily and wrap the filling tightly. 🙂
Can you make it the night before for lunch the next day or is it better to make that morning? My family would love these. I just don’t want the rice to get to hard and the nori to get soggy like it does with leftover sushi.
Hi Angela! Sure you can! The rice gets hard, so my tip is to wrap the onigirazu with kitchen towel so the onigirazu won’t get too cold. Nori is “supposed to” be soft and wrap around the rice for onigirazu. To be able to wrap nicely, we use hot rice and naturally nori will be wilted from the steam, similar to sushi roll.
I gave this a try today and it tasted fantastic! My results didn’t look nearly as pretty as yours but that’s all on me there… I don’t have any skill when it comes to making food look pretty. Thank you for posting this!
Hi Katie! Awesome! So happy to hear that you liked it! I pay extra attention to food presentation when it comes to photographing my recipes… but I don’t always spend the same amount of time plating or making for my daily food preparation. I need to convince my readers the recipe is “delicious”. Haha. 😉
Will the nori become soggy from the moisture in the rice?
For Onigirazu, the nori is supposed to be moistened from the warm/hot rice that you put on. If it’s too crispy, nori won’t be able to wrap around the rice and ingredients nicely. So it’s purposely softened. Some Onigiri uses crisp nori (which is my favorite) while other Onigiri might be wrapped with nori right after squeezed into a ball shape. There are different kinds for Onigir when it comes to nori, but for Onigirazu, always soften. It won’t be “soggy”, but it sticks to the rice and bind everything together. Hope this makes sense. 🙂
Dear Nami,
Thank you very much for your reply. I will surely try making it for my son who loves onigiri.
Can this be kept overnight? I want to pack it for my lunch but do not have time in the morning.
Hi Yuu! Sure, you can! I recommend keeping in the fridge, but the rice will get harden in the cold fridge. So what I do is to wrap/cover the Onigirazu with kitchen towel, so that Onigirazu doesn’t get too cold (but cool enough for food safety). Hope this helps! 🙂
Thanks for the advice. Just wanted to check if i can microwave it. Not too keen on eating cold bulgogi.
Hi Yuu! Sure you can! 🙂
What a good idea!
I was looking for healthy sandwich because in France we only have sandwiches with “french baguette”, ham, butter or tuna with mayonnaise …
I tried it with rice, egg, miso negi, miso nasu … very nice !
Thanks a lot Namiko
HI Aurelie! I love French baguette so I’d totally enjoy the French sandwich anytime… 🙂 Thank you for trying this recipe! Negi Your combination sounds FANTASTIC!!! I wish I could have a bite. 🙂 Thank you for your kind feedback. 🙂
Perfect! I was wondering what to make for a trip to North Carolina next month on a 7hr flight via Southwest Airlines (no plane change & no food service). Hubby is tiring of Spam musubi. I think it would be yummy w/ spicy pork bulgolgi too, so I wouldn’t need to pour on the gochujang sauce.
Hi Suzy! Hope you two enjoy Onigirazu on the flight! It’s a great compact meal on the go. 😀
