Tuna Tamagoyaki (Baked Japanese Omelet)
ツナ入り卵焼き · Tsuna-iri Tamagoyaki
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Tamagoyaki, the sweet-savory Japanese omelet, is a lunchbox classic in Japan. This preschool-kitchen version folds in canned tuna and slow-sautéed onion, then bakes in the oven instead of a pan, so there is no rolling to master and every portion comes out evenly cooked and tender. The dashi, tuna and caramelized onion layer up plenty of umami, while the touch of liquid keeps the egg soft enough for even the youngest eaters. It is just as good warm at the table as it is cooled and tucked into a bento.

- 1
Finely chop the onion. Place it in a microwave-safe dish, cover with plastic wrap, and microwave at 1200W for about 1 minute 30 seconds (3 minutes at 600W). Heat the oil in a frying pan and sauté the onion over medium heat for about 2 minutes, until golden brown.
- 2
Drain the oil from the canned tuna.
- 3
Crack the eggs into a bowl and beat them (keeping the tips of your chopsticks against the bottom of the bowl and moving them as if cutting through the egg whites gives a smoother, prettier finish). Add the onion, tuna, seasonings, and dashi stock, and mix well.

Pour the mixture into a heatproof dish lined with parchment paper and bake in an oven preheated to 180°C (350°F) for about 20 minutes.
Cooking Notes
Adding canned tuna, sautéed onion, and dashi stock to the egg boosts the umami. Mixing in a small amount of liquid keeps the finished omelet soft and tender.
