4.8 from 132 reviews

Ramen Eggs, also known as Ajitama, are soft-boiled eggs marinated in a flavorful mixture of soy sauce, dashi broth, mirin, and sake. These eggs boast a slightly runny yolk and a savory, umami-rich taste that is perfect as a topping for ramen or as a delicious snack on their own.

Ingredients

Scale

Eggs

  • 6 large eggs (room temperature)
  • 1 tablespoon vinegar
  • water for boiling

Marinade

  • 1/4 cup soy sauce
  • 1 tablespoon dark soy sauce (optional for darker color)
  • 1 cup dashi broth
  • 1/4 cup mirin
  • 1/4 cup sake
  • 1 tablespoon sugar

Instructions

  1. Make the marinade: In a small saucepan over medium-high heat, combine soy sauce, dark soy sauce, dashi broth, mirin, sake, and sugar. Bring the mixture to a boil while whisking to combine all ingredients thoroughly. Once boiling, reduce the heat and let it simmer gently for 1 minute. Remove from heat and allow it to cool completely before using.
  2. Soft boil the eggs: Fill a medium pot with enough water to cover the eggs and add the vinegar. Bring to a rolling boil over high heat. Using a spider strainer or slotted spoon, carefully lower the room temperature eggs into the boiling water. Gently rotate the eggs for the first 2 minutes to center the yolk. Lower the heat to medium and simmer for exactly 6 minutes and 30 seconds for that perfect soft-boiled center.
  3. Chill and peel the eggs: Using the slotted spoon or spider strainer, transfer the eggs immediately into an ice-water bath ensuring they are fully submerged. Let them chill for at least 10 minutes to stop cooking and firm up the whites. Gently crack and peel the eggs, then pat them dry with paper towels.
  4. Marinate the eggs: Place the peeled eggs into a large ziplock bag or airtight container along with the cooled marinade. Seal and refrigerate for a minimum of 8 hours or overnight. For even flavor distribution, gently rotate or flip the eggs halfway through the marinating time.
  5. Serve: Remove the eggs from the marinade just before serving. Slice each egg in half lengthwise using a sharp knife, string, or cheese cutter for a clean cut. Serve atop ramen bowls or enjoy as a flavorful snack.

Notes

  • Use room temperature eggs to avoid cracking when boiling.
  • The optional dark soy sauce adds a richer color and deeper flavor but can be omitted if unavailable.
  • Adjust marinating time depending on how strong you want the flavor; shorter for milder taste.
  • For a fully set yolk, increase boiling time slightly; reduce for a runnier yolk.
  • Store marinated eggs in the refrigerator and consume within 3 days for the best taste and safety.
