Key Ingredients & Substitutions
Japanese Short-Grain Rice: This rice is sticky and perfect for shaping into balls. If you can’t find it, Arborio rice can be a substitute. Just make sure it’s cooked well to maintain stickiness.
Tuna: I prefer using tuna in oil for a richer flavor, but tuna in water works too. If you’re avoiding tuna, try canned salmon or chickpeas for a vegetarian option.
Japanese Mayonnaise: Kewpie mayonnaise has a unique taste, but regular mayo can also be used. For a lighter version, mix some yogurt with mayo!
Furikake: This adds a great flavor profile to the rice. If you don’t have it, finely chopped nori (seaweed) or sesame seeds can be a nice alternative.
How Do You Shape Perfect Rice Balls?
Shaping rice balls may seem tricky, but it’s pretty straightforward! The key is to have wet hands to avoid stickiness. Here’s how to do it:
- Take about 3 tablespoons of rice and flatten it in your palm gently.
- Place a heaping tablespoon of the tuna mixture in the center.
- Carefully fold the rice around it, ensuring it’s fully enclosed.
- Gently mold it into a ball, applying just enough pressure so it holds its shape without squishing.
- Roll it lightly between your hands for a smoother finish.
Don’t worry if your first few attempts aren’t perfect; practice makes it easier each time! Enjoy creating these tasty bites!

How to Make Tuna Rice Balls
Ingredients You’ll Need:
- 2 cups cooked Japanese short-grain rice (preferably slightly cooled but still sticky)
- 1 can (about 5 oz / 140 g) tuna in oil or water, drained
- 2 tablespoons Japanese mayonnaise (or regular mayo)
- 1 teaspoon soy sauce
- 1 tablespoon chopped green onions (optional)
- 1 tablespoon furikake (Japanese rice seasoning) or finely chopped nori seaweed
- 1 teaspoon toasted sesame seeds (optional)
- A small bowl of water (to wet hands for shaping)
- Soy sauce for dipping (optional)
How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and shape the rice balls. If you decide to toast them, add an extra 5 minutes for cooking. It’s a quick and easy snack that’s fun to make!
Step-by-Step Instructions:
1. Prepare the Tuna Mixture:
In a mixing bowl, combine the drained tuna, Japanese mayonnaise, soy sauce, and chopped green onions (if using). Stir everything together until well mixed. This will be the flavorful filling for your rice balls.
2. Season the Rice:
Now, take your cooked short-grain rice and add the furikake (or chopped nori). Gently mix the seasoning into the rice to distribute the flavor evenly. The rice should be sticky enough to hold its shape.
3. Shape the Rice Balls:
Wet your hands with water to keep the rice from sticking. Take about 3 tablespoons of seasoned rice and flatten it slightly in your palm. Spoon about 1 tablespoon of the tuna mixture into the center.
4. Form the Balls:
Carefully fold the rice around the tuna, shaping it into a compact ball. Make sure the filling is completely enclosed. Repeat this step with the remaining rice and tuna mixture until you have made all the rice balls.
5. Optional – Toast the Rice Balls:
If you want a crispy texture, heat a non-stick pan over medium heat and place the rice balls in it. Lightly toast them for 1-2 minutes on each side until they are golden brown and crispy.
6. Serve and Enjoy:
Serve the tuna rice balls warm or at room temperature. You can offer soy sauce on the side for dipping. These little delights make for a perfect snack or part of a meal!
Enjoy your delicious Tuna Rice Balls! They’re a great blend of flavors and textures that everyone will love.
Can I Use Brown Rice Instead of White Rice?
Yes, you can use brown rice, but keep in mind that it will have a different texture and taste. Make sure it’s cooked well and still sticky enough to hold together when shaping the balls.
How Long Can I Store Leftover Rice Balls?
Leftover tuna rice balls can be stored in an airtight container in the fridge for up to 2 days. To reheat, you can warm them gently in a microwave or on a stovetop with a little oil to regain some crispiness.
What Other Fillings Can I Use?
You can get creative with the fillings! Try using cooked chicken, avocado, or even roasted vegetables. Just ensure the filling has enough moisture so it mixes well with the rice.
Can I Make These Rice Balls Vegan?
Definitely! Substitute the tuna with mashed chickpeas, avocado, or any plant-based protein, and use vegan mayonnaise. Also, check that any seasonings or sauces are vegan-friendly.
