Difficulty Level

Medium

Ingredients

  • 2 cups Japanese short-grain rice, rinsed and cooked
  • 200g (7 oz) fresh tuna steak, cut into 1-inch cubes
  • 2 tbsp soy sauce
  • 1 tbsp mirin (Japanese sweet rice wine)
  • 1 tsp sesame oil
  • 1 tbsp sake
  • 1 tsp freshly grated ginger
  • 1 tbsp finely chopped scallions
  • 1 sheet nori (seaweed), cut into strips
  • 1 tsp toasted sesame seeds, optional
  • salt to taste
  • Vegetable oil for grilling

Unlocking the Flavors: Marinating and Grilling Techniques

Begin by immersing the fresh tuna cubes into a marinade crafted from soy sauce, mirin, sake, sesame oil, and grated ginger. This infusion not onyl tenderizes the tuna but imbues it with deep, layered umami notes that define the savoring Grilled Tuna Onigiri experience. Allow the tuna to rest in the marinade for at least 30 minutes in the refrigerator, stirring occasionally for even absorption.

Preheat a grill pan or non-stick skillet on medium-high heat and lightly oil it to prevent sticking. Grill the marinated tuna cubes, turning carefully, until they develop a slight char and release their aromatic juices-approximately 3 to 4 minutes per side. This process locks in moisture while adding a subtle smokiness that contrasts beautifully with the mild rice.

Step-by-Step Instructions

  1. Prepare the rice: Cook the short-grain rice according to package instructions. when finished, let it cool slightly but remain warm enough to shape.
  2. Marinate the tuna: Combine soy sauce, mirin, sake, sesame oil, and grated ginger. Add tuna cubes, toss gently, and refrigerate for 30 minutes.
  3. Grill the tuna: Heat oiled grill pan over medium-high heat. Grill the tuna until nicely seared on all sides,about 8 minutes total. Remove and set aside to rest.
  4. Shape the onigiri: Wet your hands with water and sprinkle with a pinch of salt to prevent sticking. Take a handful of warm rice and flatten it slightly in your palm.
  5. Assemble: Place a few grilled tuna cubes in the center of the rice, then mold the rice around the tuna, shaping it into a firm triangle or oval.
  6. Wrap with nori: Place a strip of nori around the onigiri to add texture and flavor.
  7. Garnish and serve: Sprinkle toasted sesame seeds and chopped scallions on top for an extra pop of color and flavor.

Tips for Success

  • Rice temperature: Handling the rice when it’s warm but not hot helps form onigiri without tearing.
  • Marinating time: Extend marination up to 1 hour for more intense flavor; avoid over-marinating as acidity may affect texture.
  • Grilling alternative: Use a charcoal grill if available to introduce authentic smokiness.
  • Make-ahead: Prepare the grilled tuna in advance and refrigerate; assemble onigiri just before serving for optimal freshness.
  • Substitutions: For a lighter twist, swap tuna for grilled salmon or skip grilling altogether and use canned tuna mixed with Japanese mayo.
