Unadon (鰻丼) is a classic Japanese comfort dish that dates back to the Edo period. While traditional preparation involves a laborious process of butterflying, skewering, and grilling raw freshwater eel over charcoal, this accessible home version utilizes pre-grilled eel (kabayaki). By briefly pan-frying the eel and simmering a quick, savory-sweet tare sauce, you can achieve that sought-after glossy finish and tender texture without the intensive prep work.

Ingredients

Instructions

  1. 1Slice the pre-grilled eel
    Pre-grilled eel being cut into rectangular blocks on a wooden cutting board with a knife.

    Score the pre-grilled eel lightly and cut it into neat rectangular blocks on a wooden cutting board using a sharp knife.

    Tip: Choosing pre-grilled eel makes home preparation much easier and saves time processing raw fish.
  2. 2Blanch the vegetables
    Broccoli florets and carrot slices being blanched in boiling water.

    Boil a pot of water, add a little salt, and blanch the broccoli florets and carrot slices briefly before setting them aside.

    Tip: Adding salt to the boiling water helps maintain the vibrant green color of the broccoli.
  3. 3Pan-fry the eel
    Sliced eel pieces being pan-fried in a skillet.

    Lightly pan-fry the sliced pre-grilled eel pieces in a pan to improve their texture and warm them through.

    Tip: Use gentle heat and handle with care or chopsticks to keep the eel pieces intact.
  4. 4Heat cooking wine and white liquor
    Cooking wine and white liquor heating in a wok.

    Add two spoons of cooking wine and one spoon of white liquor (or sake) to the wok. Heat gently to evaporate the harsh alcohol notes before building the sauce.

    Tip: Evaporating the alcohol removes harsh raw tastes and leaves behind a mellow aroma for the sauce.
  5. 5Add soy sauce and sugar
    Light soy sauce and sugar being added to the sauce base in a wok.

    Stir in one and a half spoons of light soy sauce and one spoon of white sugar. Continue stirring constantly over low heat until the sugar completely dissolves.

    Tip: Stir continuously on low heat to help the sugar dissolve evenly into the liquid.
  6. 6Simmer the secret sauce
    Sauce simmering and reducing on low heat in a wok.

    Pour in a splash of clean water and half a spoon of steamed fish soy sauce. Simmer the mixture on low heat for about ten minutes until it reduces into a slightly thick, glossy glaze.

    Tip: Watch the heat closely during the final minutes to prevent the thick sauce from scorching.
  7. 7Place eel on rice
    A wooden spatula placing a glazed eel piece on top of a mound of white rice.

    Using a wooden spatula, gently transfer the cooked eel pieces onto the freshly molded mound of white rice on a serving plate.

    Tip: Arrange the pieces cleanly to make the plating look more appealing and structured.
  8. 8Add vegetables
    Sliced carrots and broccoli being arranged around the rice bowl.

    Surround the rice and eel mound with the previously blanched broccoli florets and sliced carrots to add color and nutrition.

    Tip: Arrange the sliced carrots neatly along the edge of the plate for a nice aesthetic contrast.
  9. 9Pour eel sauce
    Dark eel sauce being poured from a ladle over the assembled eel rice bowl.

    Ladle the thickened, savory-sweet secret sauce generously over the arranged eel, rice, and surrounding vegetables.

    Tip: Ensure the sauce covers the eel thoroughly so the flavors seep into the rice below.

Frequently Asked Questions

You can, but preparing raw eel requires specialized filleting techniques and a charcoal grill to achieve the authentic texture and flavor. Pre-grilled eel is highly recommended for home cooks.
In this context, it refers to a clear cooking alcohol like Chinese baijiu or Japanese shochu. You can easily substitute it with dry sake or simply use extra cooking wine.
Even though it is already fully cooked, a quick pan-fry revitalizes the texture, warming the natural fats and giving the skin a slightly crisp finish before the sauce is applied.
