Ingredients You’ll Need
The magic of these Salmon Onigiri Rice Balls lies in their simplicity—every ingredient plays a crucial role, from the fragrant rice to the flavorful salmon. Gather these essentials to bring this delicious dish to life with a harmonious balance of taste, texture, and color.
- Japanese short-grain rice: The stickiness of this rice is essential for shaping the onigiri and holding the filling together perfectly.
- Salmon fillet: Fresh salmon is pan-fried and flaked for that rich, buttery flavor you’ll want in every bite.
- Butter: Adds a luscious, creamy note that enhances the salmon’s mild flavor and creates that melt-in-your-mouth quality.
- Soy sauce: Provides a salty, umami punch that balances the richness of the salmon and butter.
- Spring onions: Fresh and crisp, they bring a subtle sharpness that cuts through the richness.
- Toasted sesame seeds: Add a nutty aroma and a satisfying little crunch in every mouthful.
- Nori sheets (seaweed): Optional but highly recommended for wrapping the rice balls, introducing a lovely umami depth and an extra layer of texture.
- Salt: To season the rice lightly, bringing out all the natural flavors.
How to Make Salmon Onigiri Rice Balls
Step 1: Cook the Rice Perfectly
Start by rinsing the Japanese short-grain rice thoroughly until the water runs clear to remove excess starch. Cook the rice according to your rice cooker’s instructions or on the stovetop, aiming for a tender but sticky consistency that’s crucial for shaping the onigiri. Once cooked, sprinkle a pinch of salt over the rice and fluff it gently with a wooden spoon to cool slightly before handling.
Step 2: Prepare the Salmon Filling
Heat butter in a pan over medium heat and add the salmon fillet. Cook it gently until it flakes easily with a fork and has that gorgeous golden-buttery finish. Add a splash of soy sauce to the pan and toss the salmon flakes to coat evenly. Stir in finely chopped spring onions and toasted sesame seeds, mixing well. This filling will be the star of your Salmon Onigiri Rice Balls.
Step 3: Shape the Onigiri
With clean, slightly wet hands to prevent sticking, take a handful of warm rice and flatten it into a small patty. Spoon a generous amount of the salmon mixture into the center. Carefully mold more rice around the filling, pressing gently but firmly into a triangular or oval shape. The goal is to compact the rice without squashing it, ensuring the Salmon Onigiri Rice Balls hold their shape beautifully.
Step 4: Wrap with Nori (Optional)
For a traditional touch and added flavor, wrap each rice ball with a strip of nori seaweed. This not only adds umami but also makes the onigiri easier to handle and eat on the go. If you prefer, you can serve them without nori—either way, they remain irresistibly tasty.
How to Serve Salmon Onigiri Rice Balls

Garnishes
To take these rice balls to the next level, sprinkle a few extra toasted sesame seeds on top for added crunch and visual appeal. You can also add a light brush of soy sauce or a drizzle of mayo mixed with a touch of wasabi for a creamy, spicy kick that complements the salmon beautifully.
Side Dishes
Salmon Onigiri Rice Balls make a fantastic stand-alone snack, but pairing them with pickled vegetables, miso soup, or a fresh salad brings harmony to the meal. The tang of pickles cuts through the richness of the salmon, while soup warms you up and completes the Japanese experience perfectly.
Creative Ways to Present
Try placing the Salmon Onigiri Rice Balls on a bamboo leaf or in a traditional bento box to elevate the presentation. You can shape them into fun molds for kids or slice them into smaller bite-sized pieces for parties. The versatility in serving keeps this classic dish fresh and exciting every time you enjoy it.
Make Ahead and Storage
Storing Leftovers
If you have leftover Salmon Onigiri Rice Balls, wrap each ball tightly in plastic wrap and store them in the refrigerator. They stay fresh for up to 24 hours, making them a convenient snack or lunch option the next day. Just keep in mind that the rice might harden slightly, but it’s still delicious.
Freezing
To freeze, wrap the rice balls individually and place them in an airtight container or freezer bag. Frozen Salmon Onigiri Rice Balls keep well for up to one month. When you’re ready, thaw them in the refrigerator overnight to maintain the texture and flavor.
Reheating
Reheat your Salmon Onigiri Rice Balls in the microwave for about 30 seconds until warm but not overcooked. You can also use a steamer to gently warm them through, which helps keep the rice moist and soft, restoring that perfect fresh-made texture.
FAQs
Can I use canned salmon for Salmon Onigiri Rice Balls?
Absolutely! While fresh salmon offers the best flavor and texture, canned salmon can be a convenient substitute, especially when mixed with butter and soy sauce to boost taste.
Is it necessary to use short-grain rice?
Yes, short-grain rice is preferred because of its stickiness, which makes shaping the onigiri easier and keeps the rice ball intact. Long-grain rice won’t hold together as well.
How do I prevent the rice from sticking to my hands?
Keep a small bowl of water nearby and wet your hands lightly before shaping the rice balls. This prevents sticking without adding excess water to the rice.
Can I make these vegetarian?
While Salmon Onigiri Rice Balls rely on salmon for flavor, you could substitute the filling with seasoned tofu flakes or sautéed mushrooms for a vegetarian twist.
What is the best way to store nori when wrapping onigiri?
Wrap the rice balls with nori just before eating to avoid sogginess. If preparing ahead, keep nori sheets dry in an airtight container until ready to use.
