Yaki onigiri or Japanese grilled rice ball is a popular snack or side dish in Japan. There are several ways to make irresistibly crispy rice balls at home. The most authentic way is by making it on a grill over charcoal. However, since many households donβt have a charcoal grill, the more common method is to pan fry, or to use an air fryer or conventional oven. This recipe is all about how to make the best sweet and savory yaki onigiri (Japanese grilled rice ball) in a pan with only 6 ingredients.

Onigiri filling
For this recipe, I am filling my onigiri with teriyaki spam. If you like spam musubi, then youβll definitely like this. Feel free to fill the onigiri with your choice of filling or none. More authentic yaki onigiri is usually not filled because the tare or sauce on the outside has enough flavors.
Pan fry tips
I have a few yaki onigiri recipes I made in the air fryer. If you want to make it in the air fryer, click on this link here. But this one is for those who donβt use an air fryer. It is just as easy and tasty!
- Make sure to crisp the onigiri in the pan without adding any sauces first. This is important because this will ensure a crispy onigiri.
- Once you put the tare sauce on, it will char quickly so be careful. Because of the sugar content, tare sauce is prone to burning quickly. 1-2 coats of sauce on both sides of the onigiri should be enough tare. Some charred parts are good, but you donβt want them burnt.
- Serve hot if you want it to be crispy. You can make the onigiri beforehand and have it in the fridge, but pan fry it before you eat it so you can enjoy it crispy. Yaki onigiri is still good at room temperature, but it wonβt be crispy.

Tare Sauce ingredients
The tare sauce is an important part of making yaki onigiri. Here are the ingredients:
- Soy sauce β I like to use Japanese soy sauce. Feel free to use what you have. However, keep in mind soy sauce tastes different based on brands, how it is made, ingredients, etc.
- Mirin β Mirin is Japanese sweet cooking wine. This not only adds sweetness but also a lot of flavor.
- Sake β I use cooking sake because it costs less than drinking sake. If you donβt want to use sake, you can substitute it with water, but flavor wonβt be the same.
- Sugar β I am using white granulated sugar.
