If you’re looking for an easy way to bring the flavours of Japan into your kitchen, Japanese miso-glazed eggplant, known as Nasu Dengaku, is a wonderful place to start. This classic dish pairs silky roasted Japanese eggplant with a sweet and savoury white miso glaze that caramelises beautifully in the oven.

Japanese eggplants are naturally sweeter and less bitter than the larger globe variety, with delicate skin and a creamy texture that absorbs the umami-rich glaze perfectly. Serve this versatile dish as an elegant entrée, alongside steamed rice, or as part of a Japanese-inspired feast.

What is Nasu Dengaku?

Nasu Dengaku is one of Japan’s most beloved vegetable dishes, featuring roasted or grilled eggplant finished with a sweet and savoury miso glaze. “Nasu” is the Japanese word for eggplant, while “dengaku” refers to foods brushed with a rich miso topping before being grilled or baked until beautifully caramelised.

This recipe brings back wonderful memories from my early hospitality career. At just 20 years of age, I managed a traditional Japanese restaurant in Melbourne, where I wore a kimono each day and evening while serving many classic dishes, including Nasu Dengaku. Long before I trained as a clinical nutritionist, I was captivated by the elegance, simplicity and respect for seasonal ingredients that define Japanese cuisine. Those early experiences continue to inspire my cooking today.

Traditionally, Nasu Dengaku is cooked over charcoal, allowing the miso glaze to develop a lightly smoky, caramelised finish. This oven-baked version captures those same authentic flavours, making it easy to recreate this timeless Japanese classic at home.

What is eggplant?

Eggplant (Solanum melongena), also known as aubergine in the UK and brinjal throughout India and parts of Asia, is a fruit that’s cooked and enjoyed as a vegetable. A member of the nightshade family, alongside tomatoes, potatoes and capsicums, eggplant has been cultivated for more than 2,000 years and is celebrated in cuisines around the world.

From the silky Japanese eggplants used in Nasu Dengaku to plump globe eggplants for parmigiana and smoky baba ganoush, this remarkably versatile ingredient readily absorbs herbs, spices and marinades. Its creamy texture and mild flavour make it an ideal canvas for bold seasonings such as miso, garlic, ginger and sesame.

Choosing the best eggplant

Not all eggplants are created equal, and choosing the right variety can make a real difference to your finished dish.

During my travels through Mumbai, I was fascinated by the abundance of tiny striped eggplants piled high in local markets. These beautiful purple-and-white varieties are often called Indian baby eggplants, striped brinjals or baby aubergines. Their firm flesh and slightly sweet flavour make them ideal for stuffing, curries and slow braises.

Back home in Australia, we’re more familiar with the large globe eggplant (also known as the American eggplant), recognised by its glossy, deep-purple skin and rounded shape. Globe eggplants are readily available year-round and are perfect for baking, grilling, parmigiana and dips such as baba ganoush.

For this recipe, however, I recommend using Japanese eggplants (sometimes labelled long eggplants). Their slender shape, delicate skin and creamy flesh cook quickly and absorb the sweet miso glaze beautifully. With fewer seeds and less bitterness than globe eggplants, they’re the traditional choice for Nasu Dengaku.

No matter which variety you choose, look for eggplants that feel heavy for their size, have smooth, glossy skin and a fresh green calyx. Avoid fruit with soft spots, wrinkles or dull, brown patches, as these are signs of age.

When shopping, choose eggplants that feel heavy for their size with smooth, glossy skin and a fresh green calyx. Avoid fruit with wrinkled skin, soft spots or dull patches, as these are signs that the eggplant is past its best.

Frequently asked questions

Can I use globe eggplants?

Yes. Globe eggplants work well but may require an additional 10–15 minutes of roasting because they are larger and denser.

What type of miso is best?

White (shiro) miso produces the traditional sweet glaze, while yellow or red miso create a deeper, more savoury flavour.

Can I cook this on the barbecue?

Absolutely. Grill the eggplants until tender before brushing with the glaze and finishing over indirect heat until caramelised.

Is Japanese eggplant healthier than globe eggplant?

Both varieties are nutritious and provide fibre and antioxidants. Japanese eggplants simply have a finer texture, thinner skin and a naturally sweeter flavour.

Eggplant 2 long Japanese eggplants 1 tablespoon macadamia oil White miso glaze 1/2 cup white miso paste 2 tablespoons mirin 2 tablespoons cooking sake 1 tablespoon brown sugar To serve 1 teaspoon finely grated fresh ginger 1 teaspoon black sesame seeds 2 red radishes, sliced very finely 2 spring onions, finely sliced diagonally 1 teaspoon toasted sesame oil

Instructions

1. Preheat the oven to 180°C and line a baking tray with baking paper.
2. Cut each eggplant in half lengthways. Using a sharp knife, lightly score the flesh in a criss-cross pattern, taking care not to cut through the skin.
3. If necessary, trim a very thin slice from the rounded base so each eggplant half sits flat. Brush the cut surface lightly with macadamia oil and place cut-side up on the prepared tray.
4. Roast for 20 minutes, or until the flesh begins to soften.
5. Meanwhile, combine the white miso, mirin, cooking sake and brown sugar in a small saucepan. Warm gently over low heat, stirring until the sugar dissolves and the glaze is smooth.
6. Remove the eggplants from the oven and generously brush with most of the miso glaze, reserving a little for serving.
7. Return to the oven and bake for a further 10–12 minutes, or until the glaze is bubbling and lightly caramelised. For extra colour, place briefly under a hot grill, watching carefully to prevent burning.
8. Transfer to a serving platter. Toss red radishes with grated ginger, black sesame seeds and spring onion, serve alongside eggplant, then drizzle with toasted sesame oil and the remaining glaze before serving.

Notes

Chef’s tips

• White miso creates the classic sweet, mellow flavour, but yellow or red miso will produce a richer, more robust glaze.
• Scoring the flesh allows the glaze to soak deep into the eggplant.
• Finish under the grill for beautifully caramelised edges.
• This glaze is equally delicious on roasted pumpkin, sweet potato, mushrooms or grilled tofu.
