Ingredients

  • 2 ahi tuna steaks (~4oz per person)
  • 1/4 cup rice vinegar
  • 1/4 cup soy sauce (use gluten-free soy sauce if needed)
  • 1 TB shaved ginger (or ginger paste)
  • 2 garlic cloves, minced
  • 1 tsp wasabi OR 1 tsp horseradish and 1/2 tsp crushed mustard seeds
  • 2 tsp sugar
  • 2 green onions, sliced, plus more for garnish (optional)
  • 1 TB sesame seeds
  • 1 TB olive oil
  • 1/4 cup lemon juice (juice of 1 lemon)

Instructions

  • Blend vinegar, soy sauce, ginger, garlic, wasabi (or horseradish and mustard seeds), sugar, and green onion. Taste sauce, adjust seasoning if necessary (adding more soy, sugar, ginger etc if preferred). 
  • Marinate tuna steaks in blended sauce for about 10 minutes. Sprinkle sesame seeds on top of tuna at end of marinade.
  • Heat oil in a heavy bottom pan (like a cast iron pan) on high, until oil is very hot. 
  • Reserving marinade for later, sear tuna for 15-30 seconds per side, then remove from pan. 
  • Reduce heat to medium and allow pan to cool slightly. Add marinade to pan with lemon juice, and stir with a wooden spoon. If sauce is too thick for your liking, add more lemon juice. Remove sauce from heat.
  • Slice tuna in thin long strips. If desired, leave about 1/2" at one end of the tuna steak uncut, and serve fanned on a plate with ginger soy pan sauce and extra green onion to garnish.

Notes

Recipe Variations:
  • Sweeter Sauce: Add 1/4 cup freshly squeezed orange juice to the sauce
  • Make it a Salad: Add 1 cup orange juice to the final pan sauce, and use the pan sauce as a warm salad dressing.  Remove sauce from pan, and add about 4oz fresh spinach to the pan.  Toss 30 seconds, until wilted.  Serve tuna over the spinach with the warm dressing.
