Step‑by‑Step Instructions for Tuna Mayo Rice Balls
Step 1: Combine the Ingredients
In a large mixing bowl, add the cooked sushi rice, sesame oil, Japanese mayonnaise, canned tuna, and shredded roasted seaweed. Using a wooden spoon or spatula, gently fold the ingredients together until everything is well combined, ensuring the rice is coated with the creamy mayo mixture. Aim for a uniform consistency, which should take about 2-3 minutes.
Step 2: Adjust the Mixture
Taste the mixture and adjust the creamy flavor by adding more Japanese mayo if desired. The goal is a rich yet balanced blend, so feel free to go a little over if you love that tangy kick! If the mixture feels too thick, a splash of rice vinegar can brighten up the flavor. This step helps achieve that delightful Tuna Mayo Rice Balls taste.
Step 3: Portion the Mixture
Using a spatula, press the rice mixture down firmly in the bowl to create a compact layer. With a knife, cut the mixture into 8 equal portions, similar to slicing a pizza. This method ensures even-sized rice balls for a consistent snacking experience. Each portion should hold its shape while being easy to roll into balls.
Step 4: Roll the Rice Balls
With clean hands or food-safe gloves, take one portion of the mixture and roll it gently into a ball shape, applying light pressure to form a solid shape. The Tuna Mayo Rice Balls should be smooth and cohesive, not crumbling apart. Repeat this process for each portion, placing the finished rice balls on a plate as you go.
Step 5: Serve or Chill
Once all the Tuna Mayo Rice Balls are shaped, you can serve them immediately or let them chill in the refrigerator for about 10 minutes for a cooler snacking experience. If desired, serve with a side of soy sauce or a spicy dipping sauce to elevate the flavor. Enjoy these delightful bites fresh, or store in an airtight container for up to 2 days!

Make Ahead Options
These Tuna Mayo Rice Balls are perfect for meal prep enthusiasts! You can prepare the rice mixture and form the balls up to 24 hours in advance, allowing you to save valuable time during a busy week. Simply prepare the mixture as directed and roll it into balls, then place them in an airtight container. To maintain their freshness and quality, refrigerate them and consider adding a dash of rice vinegar to prevent browning. When you’re ready to serve, just take them out of the fridge, allow them to sit for a few minutes at room temperature, and enjoy a delicious homemade snack that’s just as delightful as when first made!
