How to Make Tempura Bento

Step 1: Prepare the Rice

Cook Japanese short-grain rice according to package instructions.

Allow it to cool slightly before packing into the bento box.

Sprinkle with black sesame seeds if desired.

Step 2: Prepare the Tempura Batter

In a bowl, lightly beat the egg.

Add the ice-cold water.

Gently mix in the flour until just combined.

The batter should remain slightly lumpy for the lightest texture.

Step 3: Fry the Tempura

Heat the oil to 170–180°C (340–355°F).

Dip the shrimp and vegetables into the batter.

Fry in small batches for 2–3 minutes, or until lightly golden and crisp.

Drain on a wire rack.

Step 4: Make the Dipping Sauce

Combine the dashi stock, soy sauce, and mirin in a saucepan.

Bring to a gentle simmer for 2–3 minutes.

Allow to cool before transferring to a small sauce container.

Step 5: Assemble the Bento

Fill one section of the bento box with steamed rice.

Arrange the tempura neatly beside the rice.

Add tamagoyaki, pickled vegetables, broccoli, cherry tomatoes, and edamame in separate compartments.

Pack the dipping sauce in a leak-proof container.

Serve immediately or enjoy at room temperature.

Tips for the Best Tempura Bento

  • Keep the tempura batter ice-cold to create a light, crispy coating.
  • Avoid overmixing the batter; small lumps are ideal.
  • Let the tempura cool slightly before packing to prevent steam from softening the coating.
  • Use seasonal vegetables for the freshest flavor.
  • Pack sauces separately to maintain the crispiness of the tempura.
