by Nath Sasanasit

ไข่ตุ๋น - a quick and simple dish I used to enjoy as a kid. Typically cooked in a steamer but tastes just as nice from the microwave.


  • Large chicken eggs
  • Brown onion
  • Spring onion
  • Soup stock powder
  • Small amount of pork mince
  • Slice of ginger (optional dipping sauce)
  • Fried shallots (optional garnish)
  • Pepper
  • Water
  • Microwave safe plastic food wrap
  • Mushroom soy sauce (optional dipping sauce)
  • Large soup bowl
  • Small sauce dish
  • Microwave
  • Slice of lime
  • Sesame oil or Chili oil (optional seasoning)
  • Instructions

    Step 1

    3 Large chicken eggs, about a cm slice of large brown onion, two large strips of spring onion, a small amount of mince pork and a small slice of lime. Alternative- try minced chicken and coriander.

    Step 2

    Seasoning and garnish- Mushroom soy sauce (healthy boy brand), fried shallots, Vegeta vegetable stock powder and pepper. Alternative:- Maggi seasoning sauce, any other soup stock powder

    Step 3

    Large soup bowl for cooking and serving. Small sauce dish for optional side dipping sauce.

    Step 4

    Finely slice the spring onion and brown onion.

    Step 5

    Finely slice ginger for dipping sauce.

    Step 6

    All chopped up.

    Step 7

    Place the spring onion and brown onion into the large bowl leaving a pinch of spring onion on the side for garnish. Place the ginger into the small dish.

    Step 8

    Pour enough soy sauce into the small dish to cover the sliced ginger and sit to the side.

    Step 9

    Add a table spoon of soup stock to the large bowl. (You may need more or less depending on taste).

    Step 10

    Add a generous squeeze of lime and optional sesame or chili oil (a few drops).

    Step 11

    Add the eggs.

    Step 12

    Beat everything together using a fork.

    Step 13

    Keep beating until all ingredients are well mixed.

    Step 14

    Add water leaving about a couple of cm at the top of the bowl. Beat the water into the egg mixture until the mixture is consistent throughout.

    Step 15

    Loosely cover with microwave safe plastic food wrap.

    Step 16

    Ensure that the wrap is tightly sealed around the bowl but leave some room for the wrap to expand during cooking.

    Step 17

    Put in microwave on high for about 10 minutes. Keep watch as the egg mixture will rise during cooking. If mixture starts to overflow, pause the microwave and turn down the heat before resuming.

    Step 18

    Once cooked the egg will be firm to touch (resembling set jelly). You should be able to smell the aroma of the soup and seasoning.

    Step 19

    Garnish with remainder of spring onion and a pinch of fried shallots.

    Step 20

    Serve with steamed jasmine rice and side dipping sauce.

    Step 21

    Soup is hidden inside the egg and will be released as you cut through...

    Step 22

    Most of the ingredients in this can be substituted. The key essentials are eggs, plenty of water, a nice stock and a good beating. Try your own combination and season it to your liking!
