why make this recipe

Ramen eggs, or Ajitama, are a delightful addition to your ramen bowl. They are soft-boiled, marinated eggs that are rich in flavor.

Whether you enjoy them with ramen, as a side dish, or just as a snack, these eggs are a treat that elevate any meal.

how to make Ramen Eggs

Ingredients :

  • 6 large eggs (*see note)
  • Vinegar (optional for boiling eggs)
  • ½ cup soy sauce (light sodium)
  • ¼ cup water
  • ¼ cup mirin
  • 2 tablespoons granulated sugar

Directions :

  1. Boil the eggs: Bring a pot of water to a boil and gently place the eggs in the boiling water. Let the eggs boil for 6 minutes for the perfect soft-boiled texture. If you wish, add some vinegar to the water; two tablespoons of vinegar per 5 to 6 cups of water will make the eggs easier to peel.

  2. Shock the eggs: After 6 minutes, remove the eggs from the boiling water and shock them in ice water. Let the eggs cool completely. This process stops the cooking and helps make peeling easier. Soak them for about 15 minutes or longer if you have the time.

  3. Make the marinade: While the eggs are cooling, prepare the soy marinade. In a marinating container or a bowl, mix the soy sauce, water, mirin, and sugar. Stir until the sugar has dissolved. If you mixed in a bowl, transfer the marinade to a container for marinating.

  4. Marinate the eggs: After cooling, crack and peel the eggs. Rinse them with water if needed to remove any shell pieces. Place the peeled eggs into the marinade and allow them to soak for at least 8 hours; overnight is best. If the eggs are not completely submerged, rotate them occasionally for even flavor.

  5. Enjoy: The eggs are now ready to be enjoyed in ramen, as a side dish, or as a tasty snack. If you have leftovers, remove the eggs from the marinade after 12 to 36 hours, depending on how strong you want the flavor.

how to serve Ramen Eggs

Serve the ramen eggs sliced in half on top of your ramen bowl. They bring a wonderful creaminess and flavor to the dish. You can also enjoy them on their own as a flavorful snack or alongside rice and vegetables for a simple meal.

how to store Ramen Eggs

Store leftover ramen eggs in the refrigerator in an airtight container. It is best to remove them from the marinade after 12 to 36 hours to prevent them from becoming too salty. They can last for up to a week in the fridge.

tips to make Ramen Eggs

  • Use fresh eggs for the best results, as they will peel more easily.
  • Always shock the boiled eggs in ice water to stop the cooking process and ease peeling.
  • For a richer flavor, marinate the eggs for longer.

variation

You can add spices, like chili flakes or garlic, to the marinade to give the eggs an extra kick. Another fun variation is to use different types of soy sauce, such as dark soy sauce for a deeper color and flavor.

FAQs

1. Can I use a different type of vinegar?
Yes, any light vinegar can work, but rice vinegar is often preferred for a milder flavor.

2. What if I don’t have mirin?
If you don’t have mirin, you can substitute it with a mixture of water and a little sugar to add sweetness.

3. How long can I keep the marinated eggs in the fridge?
Marinated ramen eggs can last up to a week in the fridge if stored properly in an airtight container.
