Step-by-Step Instructions for Grilled Rice Balls
Step 1: Cook the Rice
Begin by rinsing 2 cups of short-grain rice under cold water until the water runs clear. Add the rice to a rice cooker with 2 cups of water and cook according to your device’s instructions. Once the rice is fluffy and cooked, let it sit for 10 minutes to firm up, making it easier to shape your delicious Grilled Rice Balls.
Step 2: Prepare the Miso Mixture
While the rice is cooking, mix together the miso, mirin, sake, sugar, and butter in a medium bowl. Use a fork to blend until smooth, creating a creamy mixture that’s not only flavorful but will also help to enhance the overall taste of your Grilled Rice Balls. Set this aside until the rice is ready to be shaped.
Step 3: Shape the Rice Balls
Once the rice has rested, place a sheet of cling wrap on your work surface. Scoop 1/6 of the cooked rice onto the wrap and use your hands to mold it into a ball or triangle shape. Make sure to pack the rice firmly to avoid breaking during grilling. Repeat this process with the remaining rice portions until you have an array of perfectly shaped rice balls.
Step 4: Grill the Onigiri
For the Miso Butter variation, heat a cast iron skillet over medium heat and melt 1 tablespoon of butter. Carefully place the rice balls in the skillet and grill for about 1 minute on each side until they develop a golden-brown crust. Brush the tops with the prepared miso mixture as they grill, infusing them with rich flavor and a beautiful glaze.
Step 5: Grill the Soy Sauce Onigiri
To make the Soy Sauce variation, add vegetable oil to a clean cast iron skillet and heat over medium heat. Grill the rice balls for 1 minute per side, then brush each side generously with soy sauce. Continue grilling until they’re crispy and have a delightful brown color on all edges, creating that irresistible texture characteristic of perfect Grilled Rice Balls.
Step 6: Serve the Rice Balls
Once the onigiri have achieved a delightful crunch, remove them from the skillet. Garnish with freshly chopped chives and a sprinkle of sesame seeds for added flavor and crunch. Serve warm, allowing everyone to savor these delicious Grilled Rice Balls together, whether as a snack, appetizer, or delightful side!

Tips for the Best Grilled Rice Balls
-
Rice Consistency: Use short grain rice for the perfect sticky texture. Avoid long grain rice, which won’t hold together as well for grilled rice balls.
-
Proper Shaping: Pack the rice firmly when shaping to ensure they don’t fall apart while grilling. Take your time to mold them well!
-
Watch the Heat: Keep your skillet at medium heat to prevent burning. Monitor closely, especially when using miso, as it can caramelize quickly.
-
Warm Rice: Work with warm rice for easier shaping. Cold rice can be tough and may not hold the desired shape.
-
Flavor Enhancement: Experiment with additional toppings, like everything bagel seasoning, for a unique twist on your grilled rice balls without compromising the classic flavor.
Make Ahead Options
Yaki Onigiri are perfect for busy home cooks looking to save time! You can prepare the rice and shape the rice balls up to 24 hours in advance. Just cook the rice and let it cool before shaping it into balls or triangles; then wrap each one tightly in cling wrap to maintain moisture and prevent them from drying out. For the best flavor, store them in the refrigerator until you’re ready to grill. When it’s time to enjoy your delicious grilled rice balls, simply heat your skillet and grill for about 1 minute per side until crispy. These prep-ahead tips ensure your Yaki Onigiri will be just as irresistible as if they were made fresh!
How to Store and Freeze Grilled Rice Balls
Fridge: Store your grilled rice balls in an airtight container for up to 3 days. This keeps them fresh while minimizing moisture loss.
Freezer: Wrap shaped but ungrilled rice balls tightly in cling wrap and freeze for up to 1 month. For best quality, grill them directly from frozen, adding a couple of extra minutes to the grilling time.
Reheating: To reheat cooked grilled rice balls, place them in a skillet over medium heat until warmed through and crispy again, about 2–3 minutes per side.
Thawing: If frozen, thaw your grilled rice balls overnight in the fridge before reheating for the best results.
