Ramen Eggs (Ajitsuke Tamago)

Japanese marinated soft boiled eggs (Ajitsuke Tamago) are easy to make at home so that you can always have an egg with your ramen.

Whenever I order ramen, the egg is always something I add on if the bowl doesn’t already include it. I love the creamy, custard-like yolk.

The basic marinade for Ajitsuke Tamago is very easy. You mix soy sauce, mirin and water together and then just let your soft boiled eggs sit in the marinade for several hours. Mirin is a type of rice wine that is sweetened. It’s a key component, so I definitely recommend buying it for making these eggs.

Soft boiled eggs are easy enough to cook but are usually a pain to peel. After discovering how much easier it is to peel eggs made in the Instant Pot, I immediately knew I had to start making my own ramen eggs again.

You don’t need an Instant Pot to make these eggs, but it does make peeling the eggs much easier. You can make your soft boiled eggs your usual way as well.

These taste so good by themselves, I had a hard time limiting myself to just one!

Japanese marinated soft boiled eggs are easy to make at home to enjoy with your ramen. The eggs are easy to make but do need at least four hours to marinate so plan to make them ahead.


  • 8 soft boiled eggs shells removed (see note)
  • tbsp  soy sauce (see note)
  • tbsp  mirin (see note)
  • 1 1/4 cups water


  • In a medium bowl, add soy sauce, mirin and water. Mix to combine. Pour liquid into a plastic bag or container that you will be using to marinate the eggs. You want to use something which allows the eggs to be completely submerged in the marinade. I put my eggs in a container that just barely fit all the eggs and marinade. I then placed a lid on top to keep the eggs from floating above the marinade.
  • Marinate eggs for about 4 hours or overnight in the fridge. I recommend overnight for the best flavor. Eggs can be eaten cold or you can add them to hot ramen broth to warm them up.


  • I used my Instant Pot to cook my eggs. Check out my Instant Pot Hard and Soft Boiled Eggs post for more details.
  • If you are looking to reduce sodium you can use low sodium soy sauce instead of regular but your eggs will also be lighter in color.
  • Mirin is a key ingredient to the flavor of these eggs, so I don't recommend substituting it for something else.

  1. Do you shell the eggs before you put into the marinade?
    How long do they last?   I love marinated eggs to munch on for lunch while fishing  in my boat….
    Do you add the eggs to the marinade after they are put into the ice bath to stop the cooking process? (using the Instant Pot)

  2. Can’t wait to make these eggs! But just to clarify, are the eggs peeled before putting them in the marinade?
