Roasted eggplant halves brushed with a sweet-spicy miso glaze and broiled until bubbling and lightly charred at the edges.
Nasu dengaku is a classic Japanese preparation of eggplant halved, scored, and broiled under a thick coating of sweetened miso until the top turns glossy and slightly charred at the edges. This version adds a touch of chili to the traditional dengaku miso for a sweet-heat balance, a common home-cook variation on the classic sweet-only glaze found in more formal restaurant settings. The technique starts with scoring the eggplant flesh in a crosshatch pattern and roasting it cut-side down first, which lets it soften fully and caramelize slightly before the miso glaze goes on -- skipping this step leaves the eggplant undercooked under a glaze that's already burnt. The dengaku miso itself is a simple reduction of miso, sugar, mirin, and sake cooked until thick enough to coat the back of a spoon, thinned slightly with a little chili paste for this version. Served as a side dish or light vegetarian main with rice, nasu dengaku is one of the dishes that best shows off how Japanese cooking treats vegetables with the same seriousness as meat or fish -- the eggplant becomes silky and custardy under its glossy, savory-sweet crust.
Serves 2
Score the cut side of each eggplant half in a crosshatch pattern, being careful not to cut through the skin. Brush with oil.
Place eggplant cut-side down on a lined baking sheet. Roast at 220C/425F for 15-18 minutes until the flesh is fully tender when pierced.
While the eggplant roasts, combine miso, mirin, sake, and sugar in a small saucepan. Cook over low heat, stirring, for 4-5 minutes until thick and glossy. Stir in chili paste.
Flip the roasted eggplant cut-side up and spread the miso glaze thickly over each half.
Broil 2-3 minutes until the glaze is bubbling and lightly charred in spots -- watch closely, as the sugar in the glaze burns quickly.
Scatter with sesame seeds and sliced scallion. Serve hot as a side or light main with rice.
Roast the eggplant fully tender before glazing -- if it's still firm, the miso will burn under the broiler before the eggplant finishes cooking.
Score the flesh in a crosshatch pattern so the glaze seeps into the eggplant rather than sliding off.
Watch the broiler closely in the final step; the sugar in dengaku miso can go from glossy to burnt in under a minute.
Omit the chili paste for the classic, purely sweet version of nasu dengaku.
Use small round eggplants cut into rounds instead of halves for individual bite-sized pieces.
Top with a sprinkle of shichimi togarashi for extra layered heat.
Refrigerate up to 3 days in an airtight container. Reheat in a 190C oven for 8-10 minutes, or briefly under the broiler, to bring back some char to the glaze.
Dengaku refers to a style of Japanese cooking where food is skewered or arranged flat and coated in a thick miso glaze before grilling or broiling, a technique documented in Japanese cooking for centuries and originally associated with tofu dengaku before extending to eggplant and other vegetables. Nasu (eggplant) dengaku remains one of the most popular versions today, especially in late-summer eggplant season.
Yes, grill cut-side down over medium heat until tender, about 10-12 minutes, then flip, glaze, and finish over slightly higher heat until the glaze caramelizes.
Older, larger eggplants can develop more bitterness -- salting the cut sides and letting them sit 15 minutes before cooking, then patting dry, helps draw out bitterness.
Regular globe eggplant works, though it has more seeds and a slightly denser texture -- cut it into thick rounds instead of halves so it cooks through evenly.
