Essential Tools and Equipment
- Rice cooker or pot
- Mixing bowl
- Skillet
- Spatula
- Measuring cups and spoons
Importance of Each Tool
- Rice cooker: Ensures perfectly cooked sushi rice every time without fuss.
- Mixing bowl: Necessary for combining ingredients thoroughly without spilling.
- Skillet: Ideal for achieving that crisp outer layer on the rice balls while grilling.

Ingredients
To make Yaki Onigiri (Grilled Rice Balls), you will need the following ingredients:
- 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
- 1/4 cup soy sauce
- 2 tablespoon mirin
- 1 teaspoon sugar
- 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 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
Once cooked, season the rice with toasted sesame seeds and sesame oil. Mix until combined. Allow it to cool until you can handle it comfortably.
Step 3: Mold the Rice
Wet your hands with water. Take about 1/2 cup of seasoned rice in your hands and firmly press it into a triangle shape. Alternatively, use a mold if available.
Step 4: Make Soy Mixture
In a small mixing bowl, combine soy sauce, mirin, and sugar. Mix well until the sugar is dissolved. Set aside this flavorful mixture for later use.
Step 5: Grill
Lightly coat your skillet with oil over medium heat. Grill each onigiri until all sides are crispy and golden brown; this should take about 2–3 minutes on each side. Avoid flipping too often to keep them intact.
Step 6: Season with Soy Sauce Mixture
Reduce heat to low. Brush one side of each onigiri with the soy sauce mixture before flipping to caramelize; cook for about 10–15 seconds per side. Be cautious as they can burn quickly! Once done, sprinkle furikake seasoning while warm if desired, wrap with nori strips, and enjoy!

Yaki Onigiri (Grilled Rice Balls) are wonderfully versatile and can be enjoyed in various ways. Here are some serving suggestions to elevate your experience with these delicious snacks.
Pair with Dipping Sauces
- Soy Sauce: A classic choice, providing a savory flavor that complements the rice balls.

Wrap in Nori
- Nori Strips: Use cut nori sheets to wrap around each grilled rice ball, adding umami and making them easier to hold.
How to Perfect Yaki Onigiri (Grilled Rice Balls)
Creating the perfect Yaki Onigiri requires attention to detail. Follow these tips to ensure your rice balls turn out delicious every time.
- Use Sushi Rice: The sticky texture of sushi rice helps the balls hold their shape better than regular rice.
- Wet Your Hands: Before molding the rice, wet your hands to prevent sticking and make shaping easier.
- Don’t Overcook: Avoid overcooking the rice; it should be fluffy and slightly firm for optimal grilling results.
- Medium Heat is Key: Grill on medium heat to achieve that crispy exterior without burning the outside while leaving the inside undercooked.
- Brush Soy Sauce Sparingly: When caramelizing with soy sauce, use just enough to coat without oversaturating the rice balls.
- Experiment with Fillings: Feel free to add fillings like grilled chicken or vegetables inside the onigiri for added flavor.
Best Side Dishes for Yaki Onigiri (Grilled Rice Balls)
To complement your Yaki Onigiri, consider these delightful side dishes that will enhance your meal experience.
- Edamame: Lightly salted edamame provides a healthy snack rich in protein.
- Miso Soup: A warm bowl of miso soup pairs well, offering comforting flavors.
- Pickled Vegetables: Tangy pickles balance the richness of grilled rice balls nicely.
- Teriyaki Chicken Skewers: These sweet and savory skewers make for a hearty addition alongside onigiri.
- Seaweed Salad: A fresh seaweed salad enhances the meal with its crunch and umami flavor.
- Tempura Vegetables: Crispy tempura adds texture and complements the soft onigiri beautifully.
- Cucumber Salad: A refreshing cucumber salad dressed in vinegar offers a light contrast to grilled rice balls.
Common Mistakes to Avoid
Making Yaki Onigiri (Grilled Rice Balls) can be simple, but a few common mistakes can affect the final result. Here’s how to avoid them:
- Using the wrong rice: Always use sushi rice or short-grain rice for the best texture. Long-grain rice will not hold its shape well.
- Not washing the rice: Failing to wash the rice can lead to excess starch, making the onigiri mushy. Rinse until the water runs clear for perfect grains.
- Ignoring cooling time: Working with hot rice makes it difficult to mold. Let the rice cool to a manageable temperature before shaping your onigiri.
- Overcooking or undercooking the onigiri: Keep an eye on grilling time; overcooked onigiri can burn while undercooked ones may fall apart. Aim for a crispy, golden brown surface.
- Skipping seasoning adjustments: Each soy sauce brand varies in saltiness. Taste your soy mixture and adjust according to your preference for optimal flavor.

Storage & Reheating Instructions
Refrigerator Storage
- Store in an airtight container for up to 3 days.
- Allow Yaki Onigiri to cool completely before refrigerating to prevent moisture buildup.
Freezing Yaki Onigiri (Grilled Rice Balls)
- Wrap each onigiri individually in plastic wrap and place them in a freezer-safe bag.
- They can be frozen for up to 2 months.
Reheating Yaki Onigiri (Grilled Rice Balls)
- Oven: Preheat oven to 350°F (175°C). Place onigiri on a baking sheet and heat for about 10-15 minutes until warm.
- Microwave: Use a microwave-safe dish and cover with a damp paper towel. Heat in short intervals of 30 seconds until warmed through.
- Stovetop: Lightly coat a pan with oil over medium heat. Sear on each side for about 2-3 minutes until heated and crispy again.
