What is Miso Eggplant (Miso Aubergine)?
This dish is known in Japan as nasu dengaku. Eggplants are halved, scored, brushed with sesame oil, then roasted until tender. They're finished with a miso glaze that caramelises under the grill into a golden, savoury-sweet topping.
Outside Japan you'll hear it called miso aubergine, miso eggplant, or miso-glazed eggplant. It's especially popular in autumn when eggplants are in season, but honestly, it's good to make any time of year.

This is an overview with my guidance and tips. See the recipe card below for exact quantities.
- Eggplant (aubergine): Japanese eggplants have thinner skin and a sweeter taste, but regular Italian ones work just as well and are easier to find in most supermarkets outside of Japan.
- Miso paste: White miso (shiro miso) is the best choice here. It's milder and a little sweet, which lets the flavour of the eggplant shine. Red miso is stronger and saltier which works really well in other dishes, but it can overpower this one.
- Mirin and sake: These bring sweetness and depth to the glaze, and help it caramelise beautifully.
- Sugar: A touch of sugar balances the savoury-saltiness of the miso.
- Sesame oil: Brush this on before roasting for a nutty aroma and golden colour.
- Garnishes: Spring onions, sesame seeds, and aonori (seaweed flakes) make a simple dish look and taste extra special.
How to Make Miso Eggplant (Nasu Dengaku)
Making miso eggplant is simple, but a few small details make all the difference. Here's how we do it at home.
Prep the eggplant
Start by preheating your oven. Wash the eggplant and slice off the green top. Cut it in half lengthwise so you have two long pieces.
Score the flesh
Take a sharp knife and score the inside in a criss-cross pattern. Keep the cuts shallow. This helps the glaze soak into the flesh for a more satisfying bite, but if you cut too far the eggplant can split and lose its shape.
Add sesame oil
Brush the cut sides generously with sesame oil. This adds nutty flavour and helps the surface roast to a golden colour instead of drying out.
Roast until tender
Lay the halves cut-side up on a baking tray and roast until the flesh is soft and the top is turning lightly golden. Depending on your oven and the size of the eggplant, this usually takes about 20 minutes. You are looking for silky flesh that gives easily when pressed with a fork.
Mix the glaze
While the eggplant roasts, stir together the miso paste, mirin, sake, and sugar until smooth. The mixture should be glossy and easy to spread. If it feels too thick, add a splash more mirin to loosen it.
Brush and grill
Once the eggplant is tender, brush the glaze generously over the scored flesh, making sure it seeps into the cuts. Slide the tray under a hot grill for a few minutes until the glaze is bubbling and starting to caramelise. Keep a very close eye at this stage. Miso can go from beautifully charred to burnt in seconds. You want bubbling and a few darker patches, not a blackened top.
Serve with toppings
Take the eggplant out and scatter over spring onions, sesame seeds, and aonori if you have it. Serve straight away while the flesh is still hot and silky, and the glaze is sticky and fragrant.
Serving Suggestions
Enjoy miso eggplant with a simple spread of rice, miso soup, and a couple of tasty sides to create a balanced Japanese meal at home. Pick one or more, such as:
- Homemade vegan sushi
- Japanese croquettes (korokke)
- Mushroom gyoza (pan-fried dumplings)
- Agedashi tofu
- Crispy vegetable tempura
Finish with toppings like furikake and Japanese pickles. For drinks, miso eggplant pairs perfectly with a cold Asahi, or see our Japanese beer guide for more options.
Easy Ingredient Swaps
Need to swap something? Here are easy alternatives that keep the recipe tasting great.
- No sesame seeds → Try crushed toasted peanuts or cashews.
- No eggplants → Use tofu instead. The miso glaze works beautifully on it and makes a protein-packed alternative for your rice bowl.
- Gluten-free → Swap soy sauce for tamari or a certified gluten-free option. You'll still get the same rich umami flavour.
Variations
These simple variations show how flexible miso eggplant can be:
Crispy: Sprinkle panko over the glaze before grilling. They'll toast up under the heat for a satisfying crunch.
Spicy: Add a drizzle of chili oil or a pinch of red pepper flakes to the glaze for gentle heat that balances the sweetness of the eggplant.
Nutty: Stir a spoonful of tahini into the glaze for extra creaminess and a nutty depth. It blends beautifully with the miso.
How to Store and Reheat
Store any leftover miso eggplant in an airtight container in the fridge for up to 2 days. To reheat, pop it back in a hot oven until warmed through. Avoid the microwave, it makes the flesh soggy and the glaze loses its texture.
FAQ
Yes. Roast the eggplants first, then when you are ready to serve brush on the glaze and grill until caramelised. Warm them through gently before turning up the heat to finish, so the miso does not burn.
Miso eggplant is perfect with rice, miso soup, and Japanese pickles. It also pairs well with sides like korokke, agedashi tofu, gyoza, or tempura.
You can, but red miso has a stronger, saltier flavour that can overpower the eggplant. White miso is milder and slightly sweet, which balances better with the glaze.
Yes. If you do not have sake, replace it with a splash of dry white wine or even water. The flavour will be lighter, but the glaze will still work.
It is best enjoyed fresh. Roasted eggplant does not freeze well and can turn watery once thawed.
