What is Yaki Onigiri?
Yaki Onigiri (焼きおにぎり) is a type of Japanese rice ball that is shaped into triangles, then coated with a flavorful sauce – usually soy sauce or miso base – and finally pan-fried or grilled to perfection.
The hallmark of yaki onigiri is its savory aroma from the Maillard reaction. This chemical process occurs when the seasoning on the rice, along with the natural sugars and amino acids in the rice, are exposed to heat. This reaction imparts a rich, umami-packed flavor and gives the onigiri a beautiful, deep color.
Another unique aspect of yaki onigiri is that they are typically not wrapped in nori (dried seaweed), setting them apart from other types of onigiri. This allows the grilled rice’s flavors and textures and seasoning to shine through without the additional layer.
How I Developed This Recipe
Yaki Onigiri holds a special place in my heart as one of my top three favorite onigiri variations. When developing this recipe, my goal was simple: to create the ultimate version that meets my standards.
Central to this endeavor was perfecting the sauce, which is crucial to yaki onigiri. I’ve refined the recipe to combine the best of both worlds, blending soy sauce and miso to create a rich, flavorful coating that enhances the grilled rice.
Additionally, I recognize that grilling Yaki Onigiri can be tricky compared to making regular onigiri, with potential pitfalls along the way. To help you succeed, I’ll share some essential tips to avoid common mistakes in grilling. These tips ensure that your yaki onigiri turns out perfectly crisp on the outside while remaining soft and fluffy on the inside.
Ingredients & Substitution Ideas
- Cooked Japanese Short-Grain Rice: Must-item for any onigiris. Other types of rice will not work in this recipe. For recommended brands in the U.S. and cooking instructions, see my How to Cook Japanese Rice Recipe.
- White Sesame Seeds: Mixed with rice for a subtly nutty flavor.
- Unsalted Butter: Preferable to maintain control over the dish’s saltiness. If using salted butter, reduce the amount of other salty ingredients.
- Soy Sauce: Kikkoman soy sauce is an affordable and authentic option. For more insights, visit my soy sauce guide.
- Mirin: Choose “hon mirin” (本みりん) like Hinode Hon Mirin for authentic flavor. For details, refer to my Mirin 101 article.
- Sesame Oil: Adds subtle flavor to marinades. I recommend Kadoya’s sesame oil.
- Awase Miso Paste: Central to this sauce’s flavor. While any miso can be used, I find Awase (Yellow) Miso most fitting.
- Garlic Paste: Grating fresh garlic is an alternative. The garlic pairs wonderfully with the miso and soy sauce!

Visual Walkthrough & Tips
Here are my step-by-step instructions for how to make Yaki Onigiri at home. For ingredient quantities and simplified instructions, scroll down for the Printable Recipe Card below.
STEP
Cooking the Rice
Start by cooking your rice. Use short-grain white rice, as it’s nice and sticky. This stickiness is crucial for holding the rice balls together.
I personally recommend using a rice cooker, but you can also see my post on ‘How to Make Japanese Rice on the Stove‘ for alternative methods.
STEP
Preparing the Rice
Once the rice is cooked, stir in 1 tablespoon of white sesame seeds. This step adds a subtle crunch and flavor to your onigiri. Then, divide the rice into six equal portions to keep the size uniform.
STEP
Shaping the Rice Balls
Now, shape six rice balls. Using an onigiri mold really helps to pack the rice tightly without breaking it.
Shaping by hand?
Prepare a bowl of ice cold water and dip your hands in for 20-30 seconds before shaping, this will stop the rice from sticking to your hands.
For more info and advice for shaping onigiri by hand, check out my post on ‘3 Ways to Shape Onigiri‘.
STEP
Drying the Onigiri
Place the rice balls on a plate and let them air dry for about 10 minutes.
This is my most important tip: letting the onigiri dry creates a thin, dry crust on the outside. It gives a slightly crispy texture and helps the rice grains bond, so your onigiri won’t fall apart when brushed with sauce.
STEP
Mixing & Applying the Sauce
Combine the soy sauce, mirin, miso paste, sesame oil and garlic paste in a small bowl until smooth and lump-free.
After 10 minutes of air drying, use a pastry brush to apply the sauce evenly over one side of each rice ball. A thin, even layer is key to prevent the onigiri from becoming too wet.
STEP
Soy Sauce Edge Brushing
Pour a small amount of soy sauce into a bowl and brush it over the edges of the rice balls. This adds an extra depth of flavor to every bite. (I don’t use the sauce for the sides, since it contains mirin and the sides won’t be cooked.)
STEP
Frying the Onigiri
Heat a frying pan on medium and add unsalted butter. Once it’s melted, place the onigiri in the pan with the sauce side facing down. Brush the tops with sauce and fry the onigiri for about 30 seconds to 1 minute on each side until they’re nicely browned.
In Japan, soy sauce and butter are a golden combo, adding a rich and delicious taste to the onigiri. If you’re grilling, just melt the butter and mix it with the sauce for that buttery flavor.
Enjoy your homemade yaki onigiri straight from the pan!

How to Store
It’s my personal preference, but I always love eating yaki onigiri straight out of the pan when they’re freshly made. Despite this, it’s also common to eat them cold and even put them in a bento box and eat them later.
If you have leftovers, you can also wrap them in plastic wrap and store them in the freezer for up to 1 month.
Place the wrapped onigiri in an airtight container to prevent freezer burn, and then microwave before eating!
FAQ
What kind of rice do you use for onigiri?
To ensure onigiri keeps its shape, you have to use Japanese short-grain white rice (the same kind used for sushi).
Is onigiri the same as sushi?
Sushi is made with sushi rice mixed with vinegar, salt, and sugar, whereas onigiri is made with simple salted rice. They are also shaped differently, so no, onigiri and sushi are not the same.
How do I stop yaki onigiri from falling apart?
Adding any sort of liquid to rice balls is going to compromise the stickiness and cause the shape to become fragile. To prevent yaki onigiri from breaking, I let them air dry on a plate for 10 minutes after shaping. This dries the outer layer of rice and creates a thin film, helping the onigiri hold its shape even after the sauce is applied.

Equipment
Ingredients
- 700 g cooked Japanese short-grain rice
- 1 tbsp white sesame seeds
- 1 tbsp soy sauce
- 1 tbsp unsalted butter
Sauce
- 2 tbsp soy sauce
- 1 tbsp mirin
- 1 tsp sesame oil
- 1 tsp miso paste
- 1 tsp garlic paste
Instructions
First, cook your rice. Use short grain white rice, preferably Japanese sushi rice or something similar. You need the rice to be sticky so that it holds it shape. I recommend using a rice cooker or see my post how to make Japanese rice on stove.
Once the rice is cooked, mix in 1 tbsp white sesame seeds and divide it into 6.
Shape 6 rice balls. I recommend using an onigiri mold so that you can pack it more tightly without breaking it. (Check out this post for 3 ways to shape onigiri) Then
Place the rice balls on a plate and allow to air dry for approx 10 minutes, turning halfway through so they can dry on both sides.
Mix the sauce ingredients (2 tbsp soy sauce, 1 tbsp mirin, 1 tsp sesame oil, 1 tsp miso paste, 1 tsp garlic paste) in a small bowl.
Once 10 minutes have passed, brush the sauce over one side of each rice ball.
Pour 1 tbsp soy sauce into a small bowl and brush it over the edges.
Heat a frying pan on medium and add 1 tbsp unsalted butter. Once it has melted, place the onigiri in the pan with the sauce side facing down. Brush the other side with the sauce and fry on each side for approximately 30 seconds to 1 minute, or until nicely browned.
Enjoy!

Notes
I recommend shaping the onigiri with a plastic mold so that you can pack it tightly without breaking it. Plastic molds are available here on Amazon. (Affiliate link)
If you grill the onigiri instead of using a pan, you can melt the butter and add it to the sauce.
Wrap leftovers with plastic wrap and store in an airtight container in the freezer for up to 1 month. Microwave to defrost. Keep in mind that reheating makes it more likely for the onigiri to fall apart.
