Ingredients

Instructions

  1. Step 1: In a small bowl, whisk together 3 tablespoons white miso paste, 2 tablespoons mirin, 1 tablespoon soy sauce, 1 tablespoon sesame oil, and 1 tablespoon brown sugar until smooth and sugar dissolves.
  2. Step 2: Preheat a charcoal grill to medium heat, about 375°F, allowing coals to develop a light ash coating for smoky flavor.
  3. Step 3: Brush both sides of 2 large eggplants cut into 3/4-inch thick slices with 2 tablespoons vegetable oil to prevent sticking.
  4. Step 4: Place eggplant slices directly on the grill grates and cook for 4-5 minutes per side until tender and grill-marked.
  5. Step 5: During the last 2 minutes of grilling, brush the miso glaze generously on each side of the eggplant slices and close the grill lid to allow glaze to caramelize without burning.
  6. Step 6: Remove eggplant steaks from grill and transfer to a serving platter.
  7. Step 7: Garnish with 1 teaspoon toasted sesame seeds and 2 tablespoons thinly sliced green onions before serving warm.
