Have you ever tried Yaki Onigiri (焼きおにぎり)? These grilled rice balls are a beloved snack and lunchtime delight in Japan, frequently gracing the menus of BBQ parties and izakaya establishments.
If you have an affinity for both rice and grilled food, you would absolutely enjoy yaki onigiri. Picture these delectable rice balls gently grilling, their exteriors crisping up to a golden brown while the rice within remains warm, tender, and irresistibly soft. A light brush of a savory glaze elevates the flavors, making them a most delicious treat!
What’s Yaki Onigiri?
The term “yaki” originates from the Japanese word for “grilled,” as seen in other popular dishes such as Teriyaki, Yakisoba, Yakiniku, and Yakitori. On the other hand, “onigiri” translates to “rice balls.” Therefore, yaki onigiri quite literally means grilled rice balls.
In the traditional preparation of yaki onigiri, rice balls are grilled over charcoal until the rice attains a desirable browned and crispy texture. Subsequently, they are brushed with either soy sauce or a miso glaze, allowing the seasoning to caramelize, creating a golden crust on the exterior.
Nowadays, as most Japanese do not have charcoal or grill in their homes, yaki onigiri is grilled using a frying pan. You’d start by shaping cooked short-grain white rice into triangular or oval shapes, akin to the regular onigiri (my recipe here), before pan-grilling them in a pan. It’s every bit as straightforward to make as it sounds!
How to Make Yaki Onigiri at Home
The Ingredients You’ll Need
- Japanese short-grain rice (cooked)
- Seasonings: soy sauce, sugar, salt, and sesame oil
- Soy sauce glaze: soy sauce and sesame oil
The Cooking Steps
- Combine the cooked rice and the seasonings. Mix it all together without making it mushy.
- Make onigiri with seasoned rice. In this recipe, I’ll show you two ways: using an onigiri mold and plastic wrap. You can choose either method.
- In a frying pan lined with parchment paper, place the rice balls and grill on all sides on medium-low heat until crispy and golden.
- Brush the soy sauce glaze on the rice balls and sear the brushed surface. Be careful not to burn.
- Transfer to a plate and enjoy while hot!
What is the Best Rice Cooker
To make the perfect rice for yaki onigiri, I like to use my Zojirushi NP-NWC10XB Rice Cooker. It makes fluffy rice every time, and it’s the best Japanese rice cooker I’ve ever used! You can get it on Amazon for $458.29, and it’s well worth it if you cook a lot of rice.
Filling or No Filling in Yaki Onigiri
These grilled rice balls can be made with fillings, but typically, it is prepared with plain or seasoned rice. I prefer mine without filling as I find filling can sometimes distract the enjoyment. Then again, the choice is yours.
Because it’s all about simplicity, you want to start with quality Japanese short-grain rice. Forming the onigiri is not something too challenging. I’ve shared step-by-step pictures and tips on how to form the rice balls in the recipe section below, so you will master it in no time. Once you have the rice balls shaped, you just need to place them on the grill, brush with the sauce and leave them to crisp up.
The Glaze Variations
Although yaki onigiri is commonly glazed with soy sauce or miso (I have Miso Yaki Onigiri recipe), you can be creative with different flavors. Here are my suggestions!
- Eel Sauce. I love my Homemade Unagi Sauce, and the savory aroma and taste of this caramelized sweet soy sauce blend perfectly with white rice, especially if you like it to be on the sweeter side.
- Teriyaki Sauce. Definitely make my Homemade Teriyaki Sauce for this!
- Negi Miso. My Homemade Negi Miso is so delicious. I may put it inside the onigiri, too, but you can definitely slather on the outside and sear a bit.
- All Purpose Miso Sauce. This Homemade All Purpose Miso Sauce goes well with everything.
What to Serve with Yaki Onigiri
To be honest, I can just devour yaki onigiri on their own, but for a balanced meal, you can pair them with:

Instructions
Before You Start…
-
Japanese short-grain white rice requires a soaking time of 20–30 minutes. The rice-to-water ratio is 1 to 1.1 (or 1.2) for short-grain white rice. Please note that 2¼ cups (450 g, 3 rice cooker cups) of uncooked Japanese short-grain rice yield 6⅔ cups (990 g) of cooked white rice. This is enough for 9 onigiri rice balls (typically 110 g each). Optional: To make 5–6 rice balls, cook 1½ cups (300 g, 2 rice cooker cups) of uncooked Japanese short-grain rice in 1⅔ cups water (400 ml) to yield 4⅓ cups (660 g) of cooked white rice.
-
Cook the rice; see how with a rice cooker, pot over the stove, Instant Pot, or donabe. To my rice cooker, I added 2½ cups water to 2¼ cups uncooked Japanese short-grain white rice. Once the rice is cooked, gather all the ingredients.
To Shape the Rice Balls
-
With an Onigiri Mold: Prepare a small bowl filled with water. Soak the onigiri mold and lid in the water to moisten so the rice doesn‘t stick to it. Remove the mold and drain the excess water.
-
Fill the onigiri mold with the hot seasoned rice all the way to the top edge, making sure to fill the corners. Cover with the lid and push down firmly. You should feel a slight resistance; if not, you may want to add a bit more rice.
-
Remove the lid. Flip over the mold onto a baking sheet or plate lined with parchment paper. Then, push the “button” on the mold‘s bottom to release your onigiri. Tip: Always dip your fingers in water before touching the onigiri to prevent the rice from sticking to them.
-
Repeat with the remaining rice.
-
Now, firmly hand-press the rice balls to keep them from falling apart while grilling. For Yaki Onigiri, you‘ll want to press the rice ball a bit more tightly than you would a regular onigiri. First, moisten both palms with a bit of water to prevent the rice from sticking. Then, pick up a rice ball in your left (non-dominant) hand. Place your right (dominant) hand on top of the rice in a “mountain” shape and gently press the triangle corner. At the same time, squeeze the fingers and heel of your bottom (left) hand to gently press the sides flat.Now, rotate the triangle corner you just pressed toward you (clockwise, if you‘re right-handed). The tip of the second corner will now be pointing up. Repeat the above “press and rotate” steps to hand press the second triangle corner and then the third, always keeping your left hand on the bottom and your right hand on top. Press and rotate a final 2–3 more times to finish.
-
In the image below, the top row is hand pressed while the bottom row is not.
-
If you don‘t want to touch the rice with your hands, you can press the onigiri with plastic wrap. Place a piece of plastic wrap on the working surface, wet your fingers, and place the onigiri in the middle.
-
Gather the corners of the plastic wrap and twist it a few times to tighten it around the rice. Form the rice into a triangle shape in the same manner that I described above.
-
Without an Onigiri Mold: You also can use plastic wrap to shape the onigiri instead of using a mold. Place a piece of plastic film on the working surface, wet your fingers, and put the rice on top. Gather the corners of the plastic film and twist it a few times to tighten it around the rice.
-
Form the rice into a triangle shape through the plastic in the same manner that I described above for hand-pressing the onigiri. Repeat with the remaining rice. Tip: To shape the onigiri with your hands the traditional way, see the step-by-step instructions and images in my Onigiri (Japanese Rice Balls) post.
To Store
-
Rice gets hard when you refrigerate it. You can individually wrap the Yaki Onigiri in plastic wrap and cover them with a thick kitchen towel and store in the refrigerator for up to 2 days. The towel will prevent the rice from getting too cold and keep the food cool but not cold. You can also store the Yaki Onigiri that are individually plastic-wrapped in the freezer for up to a month. When you‘re ready to eat, bring it back to room temperature and reheat in a microwave or frying pan.
