These eggs look simple, yet they carry deep flavor, a delicate texture, and a unique taste that instantly transforms a dish. What makes them so different, and how can such a basic ingredient become the highlight of a meal?
This recipe will guide you step by step, showing how to create Ramen Eggs at home with ease. Whether you are new to Japanese cooking or already enjoy making ramen from scratch, these eggs are simple to prepare, easy to customize, and perfect for meal prep.
Overview
Ramen Eggs, also known as Ajitsuke Tamago or 味付け玉子, are soft-boiled eggs soaked in a savory marinade. The center stays creamy while the whites absorb the sweet and salty mixture. What makes this recipe special is the balance of flavors and the slow marinating process that infuses each egg with depth.
This recipe requires only a few ingredients and very little cooking skill. The difficulty level is low, and most of the time is spent waiting while the eggs soak in the marinade. In just a few hours, you can achieve restaurant-style results.

What Are Ramen Eggs (Ajitsuke Tamago 味付け玉子)?
Ramen Eggs are marinated soft-boiled eggs commonly served on top of Japanese ramen. The outer layer becomes tinted from the marinade, while the inside stays tender and slightly custardy. These eggs are popular for their umami taste, versatility, and attractive appearance. They can be used in ramen bowls, rice dishes, salads, or enjoyed as a snack.
The marinade typically includes soy sauce, sugar, mirin, and sometimes stock for extra richness. Because the eggs soak for several hours, they develop layers of flavor that set them apart from plain boiled eggs.

Key Ingredients (材料)
Ramen Eggs 味付け玉子These simple ingredients create the rich, savory, and tender texture of homemade Ramen Eggs, known as Ajitsuke Tamago 味付け玉子. Each card explains the purpose of the ingredient and offers easy substitutions when available.

Step-by-Step Instructions
Step 1: Make the Marinade
Combine the following in a small saucepan:
- 3 tablespoons soy sauce
- 3 tablespoons water
- 2 tablespoons sugar
- 2 tablespoons mirin
- 1/2 teaspoon chicken stock powder
Place the saucepan over medium heat and bring the mixture to a gentle boil. Once it reaches a boil and the sugar has dissolved fully, turn off the heat. Set the marinade aside and allow it to cool completely. A hot marinade will overcook the eggs, so cooling is essential.

Step 2: Prepare the Boiling Water
Fill a pot with enough water to fully cover the eggs.
Add 1 tablespoon of vinegar (this helps with easy peeling, though it is not part of the main recipe).
Bring the water to a full boil over medium-high heat.

Step 3: Add the Eggs
When the water is boiling, gently lower the eggs into the pot using a ladle or spoon. Adding them gently prevents cracking.

Step 4: Control the Movement
For the first 1–2 minutes, lightly roll the eggs around the pot. This helps center the egg yolks, giving you a perfect interior when sliced.
Step 5: Cook to Your Preferred Softness
Continue boiling until the eggs reach your desired doneness.
For classic Ramen Eggs with a soft center, boil for about 6–7 minutes.
For a firmer texture, extend the cooking time by 1–2 minutes.

Step 6: Cool the Eggs
Once the cooking time is finished, immediately transfer the eggs to a bowl of cold water. This stops the cooking process and helps preserve the soft yolk.

Step 7: Peel the Eggs
When the eggs are cool, gently peel off the shells. Take your time so the whites stay smooth and intact.
Step 8: Marinate
Place the peeled eggs into a small food-safe container or zip-lock bag.
Pour in the cooled soy sauce marinade until the eggs are fully covered.
Seal the bag or close the container.
Let the eggs soak for 2–3 hours for a mild flavor or 5–6 hours for a richer, deeper taste. The longer the eggs sit, the more flavor they absorb.

Secrets to Success and Expert Tips
These simple but important tips will help you make soft-boiled, flavorful, and perfectly marinated Ramen Eggs (Ajitsuke Tamago 味付け玉子) every time:
-
♥
Roll the eggs gently during the first minute of boiling
This helps center the yolk so you get a perfectly shaped soft center when sliced. A centered yolk also gives a neat, professional look. -
♥
Shock the eggs in cold water immediately
Cooling them fast stops the cooking process and prevents the yolk from becoming firm. It also makes peeling the shells easier and cleaner. -
♥
Always cool the marinade before adding the eggs
Warm marinade will continue cooking the eggs and ruin the soft, creamy center. Make sure the mixture is completely cooled before marinating. -
♥
Use a small container or a zip bag
Keeping the eggs close together ensures the marinade covers the entire surface evenly. Rotate the eggs occasionally for perfect color. -
♥
Slice with a string for a clean cut
Soft-boiled yolks tend to stick to knives. Using a thin string or unflavored dental floss creates a smooth, restaurant-style cut every time.
Assembly
Ramen Eggs can be served in many ways, but the most popular method is topping a bowl of ramen. When assembling a dish, place the eggs on top or on the side so they stay visible. The golden center adds color and appeal, especially when paired with broth and noodles.
You can also place Ramen Eggs on warm rice, sprinkle green onions and roasted sesame on top, and drizzle a small amount of leftover marinade for added flavor. This simple preparation makes a satisfying meal.

Presentation Tips
- Cut the eggs neatly with string for a professional look.
- Arrange them with the cut side facing up.
- Add roasted sesame and chopped green onions for freshness and texture.
- Avoid soaking for longer than 24 hours, as the eggs may become too salty and change texture.
Hana’s Recipe Tips
- Use medium heat when boiling the marinade to avoid burning the sugar.
- For best results, marinate overnight if you prefer a deeper flavor, but check the salt level since soy sauce intensity varies.
- If you plan to serve the eggs with ramen, prepare them the day before to save time and allow full flavor development.
- When storing in the fridge, keep the eggs in a covered container to maintain moisture and freshness.
- To make the recipe lighter, use low-sodium soy sauce but maintain the sweetness level to keep the flavor balanced.

Storage and Make-Ahead Tips
Ramen Eggs store well in the refrigerator for up to 3 days. Keep them submerged in the marinade inside a sealed container. This maintains their texture and prevents drying.
If you want to make them ahead for meal prep, prepare a larger batch and keep them whole until serving. Avoid freezing, as freezing changes the texture of the egg whites and can cause them to become rubbery.
When reheating, avoid heating the eggs directly. Instead, allow them to sit at room temperature for 10–15 minutes before serving. They should never be reheated in the microwave.
