‘Onsen Tamago’ is a traditional Japanese low temperature Egg which is originally slow-cooked in the water of ‘Onsen’ (hot springs). What is ‘OnsenTamago’ (Wikipedia)
I cook ‘Onsen Tamago’ in the microwave. The result is similar to ‘Poached Egg’ but the yolk is cooked more than white just like ‘Onsen Tamago’. The best thing of this method is time. It takes less than 1 minute.


1 Onsen Tamago


1 Egg
1 tablespoon Water

  1. Place about 1 tablespoon of water in a small bowl. Carefully place an Egg in the water.
  2. Just in case of an accident, it is a good idea to cover the bowl with a small plate or paper towel.
  3. Cook in the microwave at 500-600W for 50 to 60 seconds.
  4. *Note: Every microwave is different. Cooking time depends on the power, the size of the Egg and the temperature of the Egg and Water. Find out your best setting and timing.
