Full Ingredients

Eggplant

• 4 small Japanese eggplants (about 1 lb / 450 g), halved lengthwise
• 2 tbsp neutral oil (canola/grapeseed/avocado), plus more if pan-frying
• Kosher salt, for drawing out moisture

Miso Glaze

• 3 tbsp white miso (shiro miso) or red miso (aka miso; if using red miso, increase sugar to 2 tbsp)
• 2 tbsp mirin
• 1 tbsp sake
• 1½ tbsp granulated sugar
• 1 tsp toasted sesame oil
• 1 tsp soy sauce (optional, for deeper savoriness)
• 1 tsp finely grated fresh ginger

To Finish

• 1 tbsp toasted sesame seeds
• 2 scallions, thinly sliced
• Steamed short-grain rice, for serving (optional)

Step-by-Step Instructions

Step 1: Prep and score the eggplant

Halve each eggplant lengthwise. Using a sharp knife, score the cut surface in a shallow crosshatch pattern (about ½ inch/1.25 cm between cuts), taking care not to pierce the skin. Lightly sprinkle the cut sides with kosher salt and let sit cut-side up for 10 minutes to draw out moisture and tame any bitterness. Pat dry with a paper towel.

Step 2: Make the miso glaze

In a small saucepan, combine miso, mirin, sake, sugar, sesame oil, soy sauce (if using), and grated ginger. Set over low heat and simmer, whisking, 2–3 minutes until smooth, glossy, and thick enough to coat the back of a spoon. Turn off the heat and keep the glaze warm. If it gets too thick, whisk in 1–2 tsp water.

Step 3: Preheat for your chosen method

For broiling: Position an oven rack 6 inches (15 cm) from the broiler and preheat to High (about 500°F/260°C). Line a sheet pan with foil for easy cleanup.

For pan-frying: Heat a large skillet (12-inch) over medium heat. Add 1–2 tbsp neutral oil once hot.

Step 4: Cook the eggplant until tender

Brush or rub the cut sides of the eggplants with the neutral oil.

Broil: Arrange eggplants cut-side up on the prepared sheet. Broil 8–10 minutes until the flesh is tender and lightly browned; the knife should slide in with little resistance. If browning too fast, move to a lower rack to finish.

Pan-fry: Place eggplants cut-side down in the hot oiled skillet. Cover and cook 6–8 minutes until deeply golden. Flip skin-side down, cover again, and cook 3–5 minutes more until fully tender.

Step 5: Brush with miso glaze and caramelize

Generously brush the warm eggplant flesh with the miso glaze, getting it into the crosshatch crevices.

Broil: Return to the broiler for 2–3 minutes until the glaze bubbles and caramelizes with tiny charred spots. Watch closely to prevent burning.

Pan: Keep eggplants in the skillet over medium to medium-high heat. Brush on glaze and cook 1–2 minutes until it bubbles and thickens on the surface.

Step 6: Garnish and serve

Transfer to a platter or individual plates. Sprinkle with toasted sesame seeds and sliced scallions. Serve immediately, with steamed short-grain rice if you like. Spoon any extra glaze from the pan over the top.

Pro Tips

• Score deeply but do not pierce the skin; this lets the glaze penetrate while keeping the halves intact.
• Use Japanese eggplants for the creamiest texture. If substituting globe eggplant, cut into thick planks or wedges and cook slightly longer.
• Simmer the glaze briefly—heat activates miso’s aroma and dissolves the sugar for a shiny finish.
• For less oil absorption, microwave the scored halves for 2 minutes before cooking; then proceed as directed.
• Toast sesame seeds in a dry pan over medium heat for 2–3 minutes to boost nuttiness.

Variations

• White vs. Red Miso: White (shiro) is mild and sweet; red (aka) is bolder. If using red miso, increase sugar to 2 tbsp to balance.
• Oven-Roasted: Roast at 425°F/220°C, cut-side up, 18–22 minutes until tender. Brush with glaze and broil 1–2 minutes to caramelize.
• Spicy: Add ½–1 tsp shichimi togarashi or a pinch of chili flakes to the glaze for gentle heat.

Storage & Make-Ahead

The miso glaze can be made up to 7 days ahead; store in a sealed jar in the refrigerator. Cooked nasu dengaku keeps 3 days refrigerated. Reheat under a hot broiler for 1–2 minutes or in a skillet over medium heat until the glaze re-bubbles. Freezing is not recommended; the texture of eggplant becomes watery.
