  • Total Time: 15 minutes
  • Yield: Makes approximately four onigiri servings 1x

Ingredients

Scale
  • 2 cups cooked short grain rice
  • 5.29 oz canned tuna (in oil recommended)
  • 2 tbsp mayonnaise
  • 2 sheets nori (seaweed)
  • 1/2 tsp salt
  • Optional: 1 tsp sesame seeds for garnish

Instructions

  1. Prepare the Rice: In a large bowl, season hot cooked short-grain rice with salt using a rice paddle. If using cold rice, microwave for 2-3 minutes before seasoning.
  2. Prepare the Tuna Filling: Drain canned tuna using a fine sieve and mix with mayonnaise in a small bowl until well combined.
  3. Cut Nori: Depending on preference, cut nori sheets in half or use whole sheets.
  4. Shape Rice Balls: Wet hands and take about 100 grams of rice; shape into a round ball and flatten slightly. Make a dent in the center and fill with tuna mixture.
  5. Form Onigiri: Fold rice over filling and mold into a triangular shape while pressing firmly.
  6. Wrap with Nori: Securely wrap nori around the base of each onigiri and garnish with sesame seeds if desired.
