Ultimate Guide to Nitamago (Japanese Seasoned Boiled Eggs)
Published: 18 May 2025
Nitamago (Japanese seasoned boiled eggs) are a delicious and essential addition to many traditional Japanese dishes, particularly ramen bowls. These soft-boiled eggs are marinated in a flavorful mixture of soy sauce, mirin, and other seasonings, creating a perfect balance of savory, sweet, and umami flavors.
Typically, the yolk remains soft and runny, adding a creamy texture to any dish they accompany. While commonly served as a topping for ramen, Nitamago can also be enjoyed as a snack or included in a bento box. Whether you’re new to Japanese cuisine or a seasoned fan, mastering the art of making ramen eggs at home will elevate your cooking to a whole new level.
What is Nitamago?
Nitamago is a popular Japanese dish made by marinating soft-boiled eggs in a flavorful mixture of soy sauce, mirin, and other seasonings. The eggs are cooked just enough to have a soft, runny yolk, which makes them ideal for ramen bowls or as an accompaniment to various Japanese meals.
In Japan, Nitamago is often used as a topping for ramen. The soft-boiled egg sits beautifully on top of the noodles, enhancing the flavor with its savory marinade. Unlike regular boiled eggs, Nitamago eggs are infused with rich flavors from the marinade, making them a perfect combination of texture and taste.
Different Types of Ramen Eggs: Nitamago vs. Ajitsuke Tamago
There are a few different kinds of eggs used in Japanese dishes, but the two most popular ones are Nitamago and Ajitsuke Tamago. Both are marinated eggs, but they differ in terms of flavor and preparation.
Nitamago, as we discussed earlier, is marinated in a mixture of soy sauce, mirin, and dashi, creating a deep umami flavor. The eggs are soft-boiled, with a slightly runny yolk that adds richness to any ramen dish.
On the other hand, Ajitsuke Tamago, or flavored soft-boiled eggs, are also soft-boiled but marinated in a simpler mixture, sometimes just soy sauce and sugar. The flavor profile is more subtle, and the eggs tend to be slightly firmer than Nitamago eggs.
How to Make the Perfect Soft-Boiled Eggs for Ramen
Making the perfect soft-boiled eggs for your ramen can be tricky, but with the right steps, you can achieve that delicious texture. To get the perfect ramen eggs with a runny yolk and firm whites, you need to boil the eggs carefully. The best way is to cook the eggs for about 6 to 7 minutes in boiling water.
Here’s how to do it:
- Bring water to a boil in a pot.
- Gently add the eggs into the boiling water using a spoon.
- Set a timer for 6 to 7 minutes, depending on how runny you want the yolk to be.
- Once the timer goes off, immediately transfer the eggs into a bowl of ice-cold water to stop the cooking process.
The result should be a soft-boiled ramen egg with a perfect balance of runny yolk and firm whites.
Boiling Time Guide to Achieve Your Preferred Egg Consistency
The boiling time for eggs is crucial to getting your preferred egg consistency. For soft-boiled eggs, you should boil the eggs for 6-7 minutes. This will give you a runny yolk and firm whites, perfect for ramen eggs. If you prefer a slightly firmer yolk, boil for 8-9 minutes. For a hard-boiled egg with no runny yolk, boil the eggs for 10-12 minutes. Always use a timer to get the perfect consistency, and remember that the size of the egg and its starting temperature can affect the cooking time. After boiling, quickly cool the eggs in ice water to stop further cooking.
Concerned About Food Poisoning?
Many people worry about food poisoning when making soft-boiled eggs. It is true that undercooked eggs can pose a risk, but if you follow safe practices, it’s usually safe to eat Nitamago. Always use fresh, high-quality eggs, and ensure that the eggs are stored at the right temperature.
In Japan, soft-boiled eggs are commonly enjoyed, but it’s important to note that Nitamago eggs are typically marinated in a soy sauce-based marinade, which may help reduce the risk of contamination. Always store marinated eggs for ramen in the fridge and consume them within 3-4 days for the best taste and safety.
Essential Ingredients for Nitamago
The key to a great Nitamago recipe lies in the ingredients. You’ll need fresh eggs, soy sauce, mirin, and dashi. The combination of these ingredients creates the perfect balance of salty, sweet, and savory flavors. Mirin for ramen eggs is essential, as it adds a sweet note that balances the salty soy sauce.
If you don’t have mirin, you can substitute it with a mixture of sugar and sake, but the flavor might be slightly different.

Tips for Perfect Marination of Nitamago
The marination process is crucial to achieving the perfect Japanese egg topping for your ramen bowls. Ensure that your soy sauce egg marinade is balanced and not too salty. The longer the eggs marinate, the more flavor they will absorb, so experiment to find the marination time that works best for you.
