  • 1 teaspoon lime juice (or lemon juice)
  • 1 teaspoon honey (optional for slight sweetness)

For the Crust:

For Garnish & Serving:

Instructions

  1. Marinate the Tuna:

    • In a small bowl, whisk together soy sauce, sesame oil, lime juice, honey, salt, and black pepper.
    • Coat the tuna steaks in the marinade and let sit for 5 minutes while preparing the sesame crust.
  2. Prepare the Sesame Crust:

    • On a plate, mix white and black sesame seeds with red pepper flakes (if using).
    • Press each side of the tuna steaks into the sesame mixture, coating them evenly.
  3. Sear the Tuna:

    • Heat 1 tablespoon oil in a skillet over high heat until very hot.
    • Sear the tuna steaks for 30-45 seconds per side (for rare) or 1-1.5 minutes per side (for medium-rare).
  4. Slice & Serve:

    • Transfer the tuna to a cutting board and let rest for 2 minutes.
    • Slice thinly against the grain and drizzle with sesame oil and soy sauce.
    • Garnish with sliced green onions and serve with lime wedges.
