Nutritional Information

Each Tuna Mayo Onigiri Rice Ball is not only delicious but also relatively balanced. While the calories can vary depending on the filling and preparation method, here’s a general nutritional breakdown for one rice ball:

  • Calories: Approximately 200-250 calories.
  • Protein: 10-15 grams primarily from the tuna.
  • Carbohydrates: Around 30-35 grams from the rice.
  • Fat: About 5-10 grams, mainly from the mayonnaise.
  • Fiber: 1-2 grams if you opt for brown rice.

This nutritional profile makes Tuna Mayo Onigiri a great choice for a light meal or snack without compromising on flavor. Additionally, by using brown rice, you can increase the fiber and nutrient content.

Ingredients Overview

For this Tuna Mayo Onigiri, you’ll need a few essential ingredients:

  • Sushi Rice: The foundation of any great onigiri. Short-grain sushi rice holds together nicely, giving you that sticky texture that’s perfect for molding.
  • Canned Tuna: I recommend using high-quality canned tuna in water or oil for a better flavor. Opt for chunk light tuna to achieve a nice texture.
  • Mayonnaise: For creaminess and flavor, a Japanese mayonnaise like Kewpie is preferable, but any mayonnaise will work.
  • Nori: This seaweed provides that distinctive Japanese touch and flavor, wrapping around the onigiri for a tasty bite.
  • Optional Extras: Feel free to add diced vegetables like cucumber or avocado for extra crunch and nutrition.

How to Make Tuna Mayo Onigiri

Here’s a simple step-by-step guide to making these delightful rice balls:

  1. Prepare the Rice: Rinse 2 cups of sushi rice until the water runs clear, then cook it according to package instructions, ideally using a rice cooker for best results.
  2. Make the Filling: In a bowl, mix drained canned tuna with mayonnaise. You can also add diced cucumber, avocado, or even a splash of soy sauce for extra flavor.
  3. Shape the Rice Balls: Once the rice has cooled slightly, wet your hands with water to prevent sticking. Take a handful of rice and flatten it into a disc shape, placing a spoonful of tuna filling in the center.
  4. Form the Onigiri: Gather the edges of the rice around the filling and mold it into your preferred shape (triangular or oval), pressing gently but firmly to ensure it holds together.
  5. Wrap with Nori: Cut nori sheets into strips and wrap them around the rice ball. Enjoy immediately or store in an airtight container.

Ingredients

  • 2 cups sushi rice

  • 2 ¼ cups water

  • 1 can tuna in water, drained 5 oz

  • ¼ cup mayonnaise

  • 1 tablespoon soy sauce

  • 1 teaspoon sesame oil

  • ¼ teaspoon salt

  • ¼ teaspoon pepper

  • 4 sheets nori, cut in half

Directions

  • Rinse the sushi rice under cold water until the water runs clear. This removes excess starch.
  • In a rice cooker or pot, combine the rinsed rice and 2 ¼ cups water. Cook according to rice cooker instructions or bring to a boil, then reduce heat and simmer for 18-20 minutes until the water is absorbed.
  • While the rice is cooking, prepare the tuna filling. In a mixing bowl, combine the drained tuna, mayonnaise, soy sauce, sesame oil, salt, and pepper. Mix until well combined.
  • Once the rice is done, let it cool slightly. Wet your hands to prevent sticking, and take about ½ cup of rice. Flatten it into your palm and create a small indentation in the center.
  • Spoon about 1 tablespoon of tuna filling into the indentation, then mold the rice around it to form a triangular shape.
  • Wrap a half sheet of nori around the bottom of each rice ball for easy handling. Repeat with the remaining ingredients.
  • Serve immediately or wrap in plastic wrap for later use.

Expert Tips for Making the Best Onigiri

  • Use Wet Hands: Wetting your hands while shaping the rice helps prevent sticking and keeps the balls neat and smooth.
  • Cooling the Rice: Allow the rice to cool slightly before shaping; hot rice can be difficult to mold and can cause burns.
  • Experiment with Fillings: Feel free to get creative! Try different flavors, textures, and seasonings to suit your taste buds.
  • Wrap At Serving Time: If you’re preparing these for later, consider wrapping them in nori just before serving to keep it crunchy.

Serving Suggestions

Tuna Mayo Onigiri is delicious on its own, but you can enhance your meal by serving it with a side of pickled vegetables, miso soup, or a simple salad. I also enjoy pairing them with green tea for a refreshing balance. If you’re having a picnic, these rice balls can be a part of a larger bento box that includes fruits, vegetables, and maybe a sweet treat for dessert.

Variations and Substitutions

If you’re feeling adventurous, here are some variations to try:

  • Spicy Tuna: Add Sriracha or chili oil to the tuna filling for a spicy kick. This variation is perfect for those who love heat!
  • Veggie Lover’s Onigiri: Swap tuna with mixed vegetables, avocado, or tofu for a vegetarian option that’s equally satisfying.
  • Different Proteins: Use chicken salad, shrimp, or other proteins in place of tuna if desired for a unique twist.

Storing and Reheating

Tuna Mayo Onigiri is best enjoyed fresh, but if you have leftovers, store them in an airtight container in the refrigerator for up to 2 days. Reheat them in a microwave for a few seconds if desired, though note that the nori may lose its crispness. To maintain their original texture, I recommend enjoying them at room temperature or cold.
