Unadon is a beloved Japanese rice bowl starring tender grilled freshwater eel lacquered in a sweet-savory soy glaze and laid over a bed of steaming short-grain rice. A quick homemade tare brings together the same deep umami you find in specialty restaurants. It's a comforting, satisfying meal that feels both humble and luxurious.

Ingredients
For the Rice
- 2 cups (400 g) Japanese short-grain rice
- 2 1/4 cups (540 ml) cold water
- 1/4 tsp salt
For the Eel and Tare Sauce
- 4 fillets (about 120 g each) pre-cooked unagi kabayaki
- 1/3 cup (80 ml) soy sauce
- 1/3 cup (80 ml) mirin
- 3 tbsp sake
- 2 tbsp granulated sugar
- 1 tbsp honey
For Garnish
- 2 scallions, thinly sliced
- 1 sheet nori, cut into thin strips
- 1/2 tsp sansho pepper or freshly ground black pepper
- 1 tsp toasted white sesame seeds
- Pickled cucumber slices, for serving
Directions
- Rinse the rice in cold water 3-4 times until the water runs clear, then drain and let rest for 15 minutes. Combine with the 2 1/4 cups water and salt in a rice cooker and start cooking, or bring to a boil in a heavy pot, cover, reduce heat to low, and cook for 18 minutes. Remove from heat and let steam, covered, for 10 minutes.
- While the rice cooks, prepare the tare: combine soy sauce, mirin, sake, sugar, and honey in a small saucepan. Bring to a gentle simmer over medium heat and cook for 4-5 minutes, stirring, until slightly syrupy and reduced by about one-third.
- Pat the unagi fillets dry with paper towels. Using a sharp knife, carefully slice each fillet lengthwise into two long strips, then cut each strip into 2-3 inch pieces suitable for laying over rice.
- Preheat a broiler or grill pan to medium-high. Lightly brush the eel pieces on both sides with about one-third of the tare sauce. Broil or grill for 2-3 minutes per side until heated through, edges just begin to caramelize, and the surface is glossy.
- Fluff the cooked rice with a wet wooden spoon and divide evenly among 4 deep bowls, shaping it gently into a flat layer. Arrange the warm grilled eel in a single layer over the rice, slightly overlapping.
- Drizzle each bowl generously with the remaining warm tare sauce, letting some pool at the base of the rice. Top with sliced scallions, nori strips, sesame seeds, and a light dusting of sansho pepper. Serve immediately with pickled cucumber on the side.
Cook’s Notes
- Pre-cooked frozen unagi from a Japanese market is the easiest and most reliable choice for home cooks; thaw it overnight in the refrigerator before use.
- Do not overcook the eel under the broiler or it will turn rubbery and lose its silky texture; just a quick 2-3 minutes per side is plenty.
- For a richer bowl, add a soft-boiled egg (ajitsuke tamago) or a sheet of toasted nori tucked along the side of the rice.
- If you cannot find sansho pepper, a small pinch of fresh lemon zest and black pepper mimics its citrusy heat.
- Leftover tare sauce keeps in a sealed jar in the refrigerator for up to 2 weeks and is excellent on grilled chicken, tofu, or salmon.
