Red Miso Glazed Japanese Eggplant - Roasted with Sweet Sake Glaze

Tender roasted Japanese eggplant glazed with a sweet-savory red miso sauce creates this traditional Japanese side dish. The eggplant is first salted to remove bitterness, then roasted until golden before being coated in a glossy glaze made from red miso, sake, mirin, and sugar. The sauce caramelizes beautifully in the oven, creating a rich umami flavor that pairs perfectly with rice and grilled meats. This technique transforms humble eggplant into an elegant vegetable dish that works well for weeknight dinners or entertaining.

Tips
Salt the eggplant for the full 10 minutes to properly draw out bitter liquids that can make the dish unpleasant.
Make sure eggplant pieces are in a single layer on the baking sheet so they roast evenly rather than steam.
Watch the final 10 minutes carefully as the miso sauce can go from caramelized to burnt quickly in the oven.

Full guide →FAQ
Can I use regular eggplant instead of Japanese eggplant?
Yes, but cut into smaller pieces as regular eggplant is larger and denser. You may need to roast a few minutes longer for proper tenderness.
What if I don't have sake or mirin?
Substitute sake with dry sherry and mirin with rice vinegar mixed with a little sugar. The flavor will be slightly different but still delicious.
How long will this keep in the refrigerator?
Store covered for up to 3 days. Reheat gently in a 350F oven for 5-10 minutes to restore the glazed texture.
