About Miso Aubergine
- Taste – A satisfying balance of savory umami from miso and gentle eggplant flavor.
- Texture – A sticky, glossy glaze coats soft, creamy eggplant flesh.
- Effort – Minimal: whisk the glaze, score and cook the eggplant, then broil to caramelize.
- Time – About a few minutes to prep, 10 minutes to make the glaze, and 10 minutes to cook the eggplant.
What is Nasu Dengaku?
Nasu Dengaku is a classic Japanese side made by glazing and broiling eggplant with miso. It’s often served alongside other miso-glazed dishes or as a flavorful complement to grilled fish, teriyaki mains, or rice bowls.
Ingredients
- Japanese eggplant – Slim, tender-skinned, and flavorful; cooks quickly and becomes creamy.
- White miso paste – Adds warm, savory depth to the glaze.
- Sugar – Balances and caramelizes the glaze.
- Sake – Contributes subtle savory notes.
- Mirin – A sweet rice wine that enriches the sauce and helps with glazing.
- Sesame seeds – Toasted, for a nutty finish.
See the recipe card below for exact quantities.
Substitutions
- Teriyaki sauce – Use teriyaki instead of miso for a familiar sweet-savory glaze.
- Unagi sauce – Offers a richer, sweet BBQ-style finish.
- Other vegetables – Try the glaze on zucchini or a mix of roasted vegetables.
- Red miso – Swap white miso for red for a deeper, more pungent flavor.
Variations
- Different eggplants – Regular or Chinese eggplants work; they may need extra cooking time.
- Shiso leaves – Add thinly sliced shiso for a fragrant, herbaceous note.
- Spicy – Stir in red pepper flakes or a touch of chili oil for heat.
- Sesame oil – A small splash boosts the nutty aroma.
Instructions
- Make the miso glaze – Combine white miso, sugar, sake, and mirin in a small saucepan over low heat. Whisk or press any miso lumps against the pan with a spatula until smooth. Simmer gently until the mixture is thick, glossy, and pourable, about 7–10 minutes, then remove from heat and set aside.
- Prepare the eggplant – Halve each eggplant lengthwise. Score the flesh in a shallow crosshatch pattern (about 1/4–1/2 inch deep) without cutting through the skin; this helps the glaze penetrate and the eggplant cook evenly.
- Cook the eggplant – Heat neutral oil (grape seed, avocado, or vegetable oil) in a skillet over medium. When shimmering, place eggplant cut-side down and press gently with a spatula to promote even browning. Cover and cook 3–4 minutes, then flip, cover, and cook another 3–4 minutes until tender.
- Transfer and glaze – Place cooked eggplant cut-side up on a baking sheet. Spoon a generous layer of miso glaze over each half, covering the flesh.
- Broil – Broil the glazed eggplant for 1–2 minutes until the glaze bubbles and caramelizes. Watch closely to avoid burning.
- Finish – Remove from the oven and sprinkle with toasted sesame seeds and thinly sliced green onions before serving.
Pro tip: If using a stainless steel pan, preheat it until very hot to reduce sticking. A well-heated pan will help the eggplant release cleanly.
What to Serve with Miso Eggplant
This savory side complements many mains. Serve with grilled or broiled fish, teriyaki salmon or chicken, unagi don, chicken katsu curry, or alongside sushi for a balanced meal. Its sweet-savory notes pair well with both Japanese and non-Japanese dishes.
