Ingredients
For the Rice Balls
- 1 1/2 cup uncooked sushi rice (short grain or medium grain)
- 2 cups water
- 2 teaspoon toasted black sesame seeds
- 2 teaspoon sesame oil
For the Marinade
- 1/4 cup soy sauce
- 2 tablespoon mirin
- 1 teaspoon sugar
Optional Toppings
- Nori sheets (cut into 2 inch pieces)

How to Make Yaki Onigiri (Grilled Rice Balls)
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
Season the cooked rice with toasted sesame seeds and sesame oil. Mix well until everything is combined. Allow it to cool until it’s manageable for shaping.
Step 3: Mold the Rice
Wet your hands with water to prevent sticking. Take about a 1/2 cup of rice in your hands and form it into a triangle shape by pressing firmly with both hands. If using an onigiri mold, fill it with rice and press firmly to achieve the desired shape.
Step 4: Make Soy Mixture
In a small mixing bowl, combine soy sauce, mirin, and sugar. Stir until fully mixed and the sugar has dissolved. Set this mixture aside.
Step 5: Grill
Lightly coat your skillet with oil and heat over medium heat. Grill each side of the onigiri until they are crispy and golden brown—about 2-3 minutes per side. Be careful not to flip them too often to maintain their shape.
Step 6: Season with Soy Sauce Mixture
Reduce heat to low. Brush one side of each grilled onigiri with the soy sauce mixture then flip them over to caramelize briefly—about 10-15 seconds—being cautious not to let them burn. Repeat this step for all sides, then sprinkle with furikake seasoning while warm. Wrap each piece in nori strips if desired before enjoying!

How to Perfect Yaki Onigiri (Grilled Rice Balls)
Perfecting yaki onigiri is all about technique and attention to detail. Here are some tips to help you achieve delicious results.
-
Use short-grain rice: Short-grain rice has the right stickiness needed to hold the shape of your onigiri.
-
Wet your hands: Keep your hands wet when molding the rice. This prevents sticking and helps form perfect shapes.
-
Don’t overcrowd the pan: Cook only a few at a time in your skillet. This ensures even grilling and crispy texture without overcrowding.
-
Monitor the heat: Grill on medium heat to avoid burning while allowing enough time for the outside to crisp up beautifully.
Best Side Dishes for Yaki Onigiri (Grilled Rice Balls)
Pairing yaki onigiri with complementary side dishes can elevate your meal. Here are some great suggestions:
- Miso Soup: A warm bowl of miso soup adds depth and warmth, making it a classic pairing.

Common Mistakes to Avoid
Making Yaki Onigiri (Grilled Rice Balls) can be a delightful experience, but there are common mistakes you should avoid to ensure your rice balls turn out perfectly.
- Skipping the rinsing step: Not washing the rice properly can lead to gummy onigiri. Rinse the rice until the water runs clear to remove excess starch.
- Using dry hands: Molding the rice without moistening your hands can make it stick. Wet your hands with water for easier shaping.
- Overcooking or undercooking the rice: Improperly cooked rice affects texture. Follow cooking instructions closely for best results.
- Ignoring the grilling time: Cooking on high heat may burn the outside while leaving the inside raw. Grill on medium heat and check regularly.
- Not seasoning adequately: Skipping the soy mixture can leave your onigiri bland. Brush evenly with the sauce for flavor enhancement.
