Japanese eggplant dusted with potato starch, deep-fried until the skin blisters and the flesh turns to silk, then served in a pool of hot dashi broth with grated daikon and ginger. The eggplant's transformation — from firm to custard-soft — is the dish's defining pleasure.
Agedashi nasu is a Japanese side dish of deep-fried eggplant in dashi broth, closely related to agedashi tofu. No single inventor is documented; the preparation belongs to the broader tradition of age-dashi dishes — ingredients dusted in starch, fried, and served in hot broth — that are izakaya staples across Japan.
A serving of agedashi nasu arrives in a small bowl: glossy, deep-purple eggplant halves, their skins blistered and slightly charred, their flesh impossibly soft — almost liquid — bathed in a savory dashi broth. The starch coating has absorbed the broth into a glossy sauce; the grated daikon and ginger cut the richness. Eaten hot, the contrast of the blistered skin and the silky flesh is extraordinary.
Agedashi nasu rests on the eggplant's transformation under heat and the starch-broth interaction. Eggplant, which is mostly water with a spongy cellular structure, collapses completely when deep-fried: the high heat flashes the water to steam, rupturing the cell walls and turning the flesh from firm to silky-soft. The potato starch coating protects the eggplant's surface during frying and then, when the hot broth is poured on, absorbs it into a glossy sauce — the same mechanism as agedashi tofu. The grated daikon, added raw, provides a cool, crisp contrast.
Variations
Some versions add bonito flakes or scallion; the starch-fried eggplant in dashi broth is the constant.

How it's made

- 13 min
Cut Japanese eggplant in half lengthwise; score the flesh.
- 22 min
Dust with potato starch.
- 36 min
Deep-fry at 170 degrees until the skin blisters and the flesh is soft.
Watch outDeep-fry at 170 degrees until the skin blisters and the flesh goes silky-soft — the water inside flashes to steam and collapses the spongy eggplant; underdone, it stays firm and hollow-tasting.
- 43 min
Warm a mixture of dashi, soy sauce, and mirin in individual bowls.
- 52 min
Place the fried eggplant in the broth.
Watch outPour the hot broth over the starch-dusted eggplant just before serving — the coating drinks it into a glossy sauce, but sits too long and it turns soggy.
- 62 min
Top with grated daikon and ginger; serve immediately.
