Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Cut 2 medium Japanese eggplants in half lengthwise and score the flesh in a crosshatch pattern about 1/4 inch deep. Brush each half with 2 tbsp vegetable oil and place cut-side up on a baking sheet.
  2. Step 2: Roast the eggplants for 20 minutes until tender and beginning to brown.
  3. Step 3: Meanwhile, in a small bowl whisk together 3 tbsp white miso paste, 2 tbsp mirin, 1 tbsp soy sauce, and 1 tbsp sugar until smooth.
  4. Step 4: Remove eggplants from oven and brush the miso glaze generously over the cut surfaces. Return to the oven and broil on high for 3-4 minutes until the glaze bubbles and caramelizes, watching carefully to avoid burning.
  5. Step 5: Divide 4 cups steamed short-grain rice among four bowls. Top each with a miso-glazed eggplant half. Garnish with 2 thinly sliced scallion stalks and 1 tbsp toasted sesame seeds before serving.
