Ajitama is a Japanese ramen egg: a soft-boiled egg that is peeled and marinated, commonly in a soy-based mixture. Its white takes on a savory flavor, while the yolk is usually jammy or slightly runny.
To make ajitama, soft-boil eggs, cool them quickly in cold water, and peel them carefully. Soak the eggs in a marinade made with soy sauce, water, and mirin or another sweetener, then refrigerate before serving.
Ajitama is usually marinated in the refrigerator for a few hours or overnight. A longer soak gives the egg a deeper color and saltier flavor, so keep the eggs fully covered and remove them once they taste as seasoned as you like.
Ajitama also works well with rice bowls, udon, soba, and other noodle dishes. Halve one over steamed rice or a grain bowl to add a savory, creamy topping without needing to serve it in ramen.
No, ajitama and onsen eggs are different. Ajitama is peeled and marinated after soft-boiling, while an onsen egg is gently cooked at a low temperature and is often served with its delicate, custard-like white.
Ajitama has a runny or jammy yolk because the egg is soft-boiled rather than cooked until firm. Cooling it promptly in cold water stops the cooking; leaving it in hot water longer will make the yolk firmer.
Keep ajitama covered in its marinade in the refrigerator and eat it within 3–4 days for best quality. Do not leave it out at room temperature for extended periods, and discard it if it develops an unusual smell or texture.
Freezing ajitama is not recommended. Thawed egg whites can become rubbery or watery, and the yolk may turn dry or crumbly, so make a small batch and refrigerate it instead.
Ajitama marinade commonly combines soy sauce, water, and mirin. Some versions add sake, sugar, or ginger; diluting the soy sauce with water helps keep the eggs from becoming overly salty as they soak.
Ajitama can be difficult to peel when the eggs are very fresh or have not been cooled promptly. After boiling, transfer them to ice water, crack the shell all over, and peel gently under running water to help separate the membrane.

Ajitama is the Japanese marinated soft-boiled egg served with ramen. The white is set while the yolk stays tender and often slightly runny; after boiling, the egg is steeped in a savoury seasoning that gives it colour and depth of flavour. It is a simple preparation, but the contrast between the firm white and creamy centre makes it a distinctive topping.
In Japan, it is a familiar addition at ramen shops and is also made at home; elsewhere, it is commonly served in ramen restaurants or added to a bowl of noodles at home. It brings protein as well as richness from the yolk. Pair it with broth, vegetables and noodles for a more rounded meal, or serve half an egg when you want the topping without making the bowl too filling.
High
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
