Step‑by‑Step Instructions for Tuna Mayo Rice Balls
Step 1: Cook Sushi Rice
Start by cooking 2 cups of sushi rice according to the package instructions. Once cooked, allow the rice to cool slightly—aim for a warm temperature to help enhance the flavors later. Use a rice cooker or stovetop method and look for that perfect sticky texture, which is essential for forming your Tuna Mayo Rice Balls.
Step 2: Prepare the Mixture
In a large mixing bowl, combine the warm sushi rice, 150 grams of canned tuna, 1 tablespoon of sesame oil, and 2 to 3 tablespoons of Japanese mayo. Gently mix the ingredients together, taking care not to mash the rice. The warmth of the sushi rice will help meld the flavors while retaining the delightful texture for your rice balls.
Step 3: Shape the Rice Balls
Once everything is well combined, press the mixture down firmly in the bowl before dividing it into 8 triangular sections. Use a sharp knife to cut the mixture neatly, ensuring even shapes. This will help create uniform Tuna Mayo Rice Balls, making them visually appealing and easy to handle when serving.
Step 4: Form the Balls
With clean hands or food-safe gloves, take each triangular section and gently shape it into a ball. Aim for a comfortable size that fits easily in your palm. As you form the balls, you can feel the stickiness of the rice, which will help them hold their shape. Make sure to serve them immediately for the best freshness and texture.

How to Store and Freeze Tuna Mayo Rice Balls
Fridge: Store leftover Tuna Mayo Rice Balls in an airtight container for up to 3 days. To maintain freshness, avoid stacking them directly on top of each other.
Freezer: For long-term storage, freeze the rice balls individually wrapped in plastic wrap for up to 2 months. Place them in a freezer-safe bag to prevent freezer burn.
Reheating: Thaw overnight in the fridge, then warm gently in the microwave for about 30 seconds. Enjoy immediately for the best texture and flavor.
Freshness Reminder: These rice balls are best when fresh, so only make as many as you can enjoy within a few days!
Make Ahead Options
These Tuna Mayo Rice Balls are perfect for meal prep enthusiasts! You can prepare the filling mixture—combining the warm cooked sushi rice, canned tuna, sesame oil, and mayo—up to 24 hours in advance. Simply refrigerate the mixture in an airtight container to keep it fresh. When you're ready to enjoy, just shape the mixture into balls and wrap them in nori if desired. This method not only saves time during your busy weeknights but also ensures each bite is just as delicious and flavorful. Remember, to maintain the best texture, it's recommended to shape the rice balls no more than a few hours before serving for optimal results!
