Ingredients
To create these delicious Yaki Onigiri (Grilled Rice Balls), gather the following ingredients:
For the Rice
- 1 1/2 cup uncooked sushi rice (short grain or medium grain)
- 2 cups water
For Seasoning
- 2 teaspoon toasted black sesame seeds
- 2 teaspoon sesame oil
For Marinade
- 1/4 cup soy sauce
- 2 tablespoon mirin
- 1 teaspoon sugar
For Assembly
- Nori sheets (cut into 2 inch pieces)
- Furikake seasoning (optional)
How to Make Yaki Onigiri (Grilled Rice Balls)
Step 1: Cook the Rice
Wash the uncooked rice under running water until it runs clear. Combine the rice and water in a rice cooker or stovetop pot. Cook until done according to your appliance’s instructions.
Step 2: Season the Rice
Once cooked, season the rice with toasted sesame seeds and sesame oil. Mix well until fully combined. Allow it to cool until safe to handle.
Step 3: Mold the Rice
Wet your hands with water. Take about 1/2 cup of rice and shape it into a triangle using both hands. If available, use a mold for consistent shapes.
Step 4: Make Soy Mixture
In a small mixing bowl, combine soy sauce, mirin, and sugar. Stir until everything is mixed well and sugar is dissolved. Set this mixture aside for later use.
Step 5: Grill
Preheat your skillet over medium heat and lightly coat it with oil. Grill each onigiri until all sides are golden brown and crispy, approximately 2-3 minutes per side. Avoid flipping too often to keep them intact.
Step 6: Season with Soy Sauce Mixture
Lower heat to low. Brush one side of each onigiri with your soy sauce mixture, then flip to caramelize for about 10-15 seconds. Be quick as it can burn easily! Brush other sides similarly while sprinkling furikake on warm onigiri. Wrap them in nori strips before serving for an authentic touch!

- Don’t skip seasoning: Adding toasted sesame seeds and sesame oil enhances both flavor and aroma.
- Grill evenly: Rotate the onigiri frequently while grilling for even browning without burning.
- Brush carefully: When applying soy sauce, brush gently to avoid breaking apart the crispy exterior.
- Experiment with toppings: Try different toppings like furikake or chopped green onions for added flavor and texture.

Common Mistakes to Avoid
Making Yaki Onigiri (Grilled Rice Balls) can be straightforward, but certain mistakes can affect the outcome. Here are some common pitfalls to watch out for:
- Using dry rice – Dry rice will not hold together well. Always wash your sushi rice until the water runs clear and ensure it’s properly cooked for optimal texture.
- Not seasoning well – Skipping or skimping on the seasoning can result in bland onigiri. Make sure to mix in sesame oil and toasted sesame seeds thoroughly before molding.
- Overhandling the rice – Pressing too hard or too often can break apart the grains. Mold the rice gently into shape, ensuring it holds without crumbling.
- Ignoring grill temperature – Cooking at too high a temperature can burn the outside while leaving the inside undercooked. Use medium heat for even grilling and perfect crispiness.
- Skipping soy sauce brushing – Not brushing with the soy mixture can lead to less flavorful onigiri. Apply it carefully as directed for that rich, caramelized taste.
