How to Make Yaki Onigiri (Grilled Rice Balls)
Follow these simple steps to create your own Yaki Onigiri at home.
Step 1: Cook the Rice
Wash the uncooked rice under running water until the water runs clear. Combine the rice and water in a rice cooker or on the stovetop and cook until done.
Step 2: Season the Rice
After cooking, season the rice with toasted sesame seeds and sesame oil. Mix well until combined. Let it cool until you can handle it comfortably.
Step 3: Mold the Rice
Wet your hands with water to prevent sticking. Take about 1/2 cup of rice in your hands and firmly press it into a triangle shape. If using a mold, fill it with rice and press down firmly.
Step 4: Make Soy Mixture
In a small mixing bowl, combine soy sauce, mirin, and sugar. Stir until well mixed and sugar dissolves completely. Set aside for later use.
Step 5: Grill the Onigiri
Lightly coat your skillet with oil over medium heat. Grill each onigiri until all sides are crispy and golden brown—about 2-3 minutes per side. Be careful not to flip too often to keep them intact.
Step 6: Season with Soy Sauce Mixture
Lower heat to low. Brush one side of each grilled rice ball with soy sauce mixture, then flip to caramelize for about 10-15 seconds. Repeat for other sides quickly to avoid burning. Sprinkle with furikake while warm, wrap with nori strips, and enjoy!

Common Mistakes to Avoid

- Not rinsing the rice – Failing to wash the sushi rice properly can lead to a sticky texture. Always rinse until the water runs clear to achieve fluffy rice.
- Using dry hands – Molded rice balls may fall apart if your hands are dry. Wet your hands with water before handling the rice for better adhesion.
- Overcooking or undercooking – Cooking rice at the wrong temperature or for too long can ruin its texture. Follow cooking instructions carefully for perfect rice.
- Skipping the seasoning – Neglecting to season the rice means missing out on essential flavor. Always mix in sesame oil and toasted sesame seeds after cooking.
- Flipping too often while grilling – Constantly flipping onigiri can cause them to break apart. Allow each side to crisp up before turning them just once.
