If you’ve ever enjoyed a bowl of authentic Japanese ramen, you’ve likely spotted a glossy, amber-coloured egg resting gently on top — the Ajitsuke Tamago (ajitama). Literally meaning “seasoned egg,” it’s a soft-boiled egg marinated in a savoury soy-based sauce that adds both taste and elegance to ramen dishes. Though it looks simple, this humble ingredient is packed with umami and is surprisingly easy to make at home.
What Exactly Is Ajitsuke Tamago?
Ajitsuke Tamago, also known as ramen egg or nitamago, is a soft-boiled egg that’s been soaked in a mixture of soy sauce, mirin, and sake. The result? A delicate balance of salty, sweet, and savoury flavours that complement the richness of ramen broth perfectly.
The magic of the dish lies in its texture — a firm white with a creamy, jam-like yolk that oozes slightly when cut. It’s a texture that Japanese chefs have perfected, and it adds a luxurious touch to any bowl of noodles.
How to Make Ajitsuke Tamago at Home
Creating Ajitsuke Tamago is far simpler than it looks. Here’s how to make it yourself:
-
Boil the eggs: Bring water to a gentle boil and cook eggs for exactly 6 to 7 minutes.
-
Cool them quickly: Transfer immediately to ice water to stop the cooking process and make peeling easier.
-
Prepare the marinade: Combine soy sauce, mirin, sake, and a little sugar in a bowl.
-
Marinate: Peel the eggs carefully and place them in the marinade for at least 4 hours, or overnight for a deeper flavour.
-
Serve: Slice in half and place on ramen, rice bowls, or salads.
The marinade not only infuses the egg with flavour but also gives the whites a beautiful golden-brown colour.

Umami-rich: The soy sauce and mirin create a deep, savoury flavour that enhances any dish.

Tips for the Perfect Ramen Egg
-
Use room-temperature eggs to prevent cracking during boiling.
-
Turn the eggs occasionally while marinating to ensure even colouring.

Store them in the fridge — they’ll last up to three days in their marinade.
