Marinated Ramen Eggs - Ajitsuke Tamago

An essential topping for our Cha Shu Ramen is our “7-minute egg”: soft-boiled and marinated (Ajitsuke Tamago).

Creamy and runny, the yolk should glisten enticingly when you slice through the marinated egg.

Super versatile, other than serving as a topping on ramen, we have it as a side dish for meals too.

When I’m making my Chashu Pork, I will always reserve some broth to make a batch of these so they have extra flavour. Below is a simpler recipe, for when you don’t have pork broth handy.


  • 6 eggs
  • 100ml soy sauce
  • 100ml sake
  • 100ml mirin
  • 2 tsp sugar
  • 200ml water
  • ice cubes, small bowl


  1. Fill a small saucepan with enough water to cover eggs (don’t add eggs yet though).
  2. Bring the pot of water to a boil, then turn down the heat to a simmer and gently lower fresh eggs in.
  3. Cook for 6-7 minutes (6 for size 6 eggs, 7 for size 7 eggs) and set a timer for it.
  4. When it’s almost done, place ice cubes into a large bowl with cold water.
  5. Remove eggs with a slotted spoon and plunge them into the ice water bath immediately to halt the cooking process.
  6. Once cooled, remove shells and place in a zip lock bag and pour in the soy sauce marinade (or broth). Let it marinate overnight before serving.
