Ingredients

To create these delicious Yaki Onigiri (Grilled Rice Balls), you’ll need 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
  • 1/4 cup soy sauce
  • 2 tablespoon mirin
  • 1 teaspoon sugar

Optional Garnish

  • 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 sushi rice under running water until it runs clear. Combine the rice and water in a rice cooker or saucepan. Cook until done, following your rice cooker’s instructions or simmering until all water is absorbed.

Step 2: Season the Rice

Once cooked, season the rice with toasted black sesame seeds and sesame oil. Mix thoroughly until combined. Allow it to cool until it’s cool enough to handle.

Step 3: Mold the Rice

Wet your hands with water to prevent sticking. Take about 1/2 cup of seasoned rice in each hand and firmly press it into a triangular shape. If you have an onigiri mold, fill it with rice and press firmly to form.

Step 4: Make Soy Mixture

In a small mixing bowl, combine soy sauce, mirin, and sugar. Stir well until fully mixed and sugar is dissolved. Set this aside for later use.

Step 5: Grill

Lightly coat your skillet with oil over medium heat. Grill each onigiri for about 2-3 minutes on each side until crispy and golden brown. Be careful not to flip too often; this helps keep them intact.

Step 6: Season with Soy Sauce Mixture

Lower heat to low and brush one side of each onigiri with your prepared soy mixture. Flip carefully to caramelize for about 10-15 seconds; work quickly as they can burn easily! Brush other sides similarly before sprinkling with furikake while warm. Finally, wrap with nori strips if desired and enjoy!

How to Serve Yaki Onigiri (Grilled Rice Balls)

Yaki onigiri makes for a delightful snack or meal. Its crispy texture and savory flavors can be enhanced by various accompaniments. Here are some creative serving suggestions to elevate your grilled rice balls.

With Dipping Sauces

  • Soy Sauce – A classic choice, offering a salty and umami flavor that complements the yaki onigiri perfectly.
  • Wasabi Mayo – A creamy and spicy dip that adds an exciting kick to each bite.
  • Sesame Dressing – A nutty dressing that enhances the sesame flavors in the rice balls.

As Part of a Bento Box

  • Vegetable Pickles – Add tangy pickled vegetables for a refreshing contrast to the warm rice balls.
  • Edamame – These protein-packed green soybeans make a nutritious side that pairs well with yaki onigiri.
  • Fruit Slices – Include some seasonal fruit slices for a sweet finish to your meal.

Wrapped in Nori

  • Nori Strips – Wrap each onigiri with nori for added flavor and texture. It gives an authentic touch while making them easier to hold.

How to Perfect Yaki Onigiri (Grilled Rice Balls)

Creating the perfect yaki onigiri comes down to technique and ingredients. Follow these helpful tips for outstanding results every time!

  • Use Short-Grain Rice – Short-grain sushi rice helps bind the onigiri together, providing the ideal texture.
  • Cool the Rice Properly – Allow cooked rice to cool before shaping; this prevents it from becoming too sticky during molding.
  • Oil Your Hands – Lightly oiling your hands while shaping will help prevent sticking and allow for easier handling.
  • Control Grill Temperature – Use medium heat to achieve a crispy exterior without burning; adjust as necessary during grilling.
  • Brush Generously with Soy Sauce Mixture – This adds flavor and caramelization; don’t skip this step for that delicious finish!

Best Side Dishes for Yaki Onigiri (Grilled Rice Balls)

Pairing yaki onigiri with complementary side dishes can enhance your dining experience. Here are some excellent options to consider:

  1. Miso Soup – A warm, comforting soup that balances the savory flavors of grilled rice balls.
  2. Cucumber Salad – A refreshing salad that adds a crunchy texture and lightness to your meal.
  3. Tempura Vegetables – Crispy battered vegetables provide a delightful crunch alongside the soft rice balls.
  4. Sautéed Greens – Lightly sautéed spinach or bok choy offers a nutritious contrast with vibrant color.
  5. Sweet Potato Fries – These add a sweet note and satisfying crunch when served alongside yaki onigiri.
  6. Rice Vinegar Slaw – A tangy slaw brings brightness and acidity, balancing out the richness of grilled rice balls.
  7. Steamed Broccoli – Simple yet nutritious, steamed broccoli adds color and vitamins to your plate.

Common Mistakes to Avoid

Making Yaki Onigiri can be a delightful experience, but there are common pitfalls you should steer clear of.

  • Skipping the rinsing step: Not washing the rice can result in overly sticky onigiri. Always rinse until the water runs clear to achieve the perfect texture.
  • Overcooking the rice: Cooking rice too long can make it mushy. Follow your rice cooker’s instructions or monitor stovetop cooking closely to ensure ideal doneness.
  • Neglecting to season: Failing to add sesame oil and seeds will lead to bland onigiri. Proper seasoning elevates the flavor and makes each bite delicious.
  • Not wetting hands: If you don’t wet your hands while shaping the rice, it will stick and be hard to mold. Always keep a bowl of water handy for easy shaping.
  • Grilling at too high a temperature: Cooking on too high heat may burn the outside before the inside is fully heated. Use medium heat for even grilling and golden-brown perfection.

Refrigerator Storage

  • Store Yaki Onigiri in an airtight container.
  • They can last up to 3 days in the refrigerator.
  • Place parchment paper between layers if stacking to prevent sticking.

Freezing Yaki Onigiri (Grilled Rice Balls)

  • Wrap each onigiri tightly in plastic wrap or aluminum foil.
  • They can be frozen for up to 2 months.
  • Use freezer-safe containers or bags for extra protection against freezer burn.

Reheating Yaki Onigiri (Grilled Rice Balls)

  • Oven: Preheat to 350°F (175°C) and bake for about 10-15 minutes until heated through.
  • Microwave: Place on a microwave-safe plate and cover with a damp paper towel. Heat in 30-second intervals until warm.
  • Stovetop: Lightly oil a skillet over medium heat and grill until crisp again, about 2-3 minutes per side.
