Step-by-step Preparation of Japanese Egg Sandwiches
Crafting the perfect Japanese egg sandwich is a delightfully rewarding experience. These sandwiches are not only tasty but also incredibly easy to put together once you break it down into simple steps. Let's dive into the preparation!
Boil the eggs to perfection
Start with the most crucial element: the eggs. For the best flavor and texture, aim for the perfect hard-boiled eggs.
- Technique: Bring a pot of water to a rolling boil. Add your large eggs and maintain the boil at medium-high heat.
- Timing is Everything: Boil the eggs for precisely 9 minutes. If you’re opting for a medium-boiled egg, remove it after 7 minutes and 30 seconds to create a creamy yolk.
- Ice Bath: As soon as the time is up, immerse the eggs in an ice bath for 2 minutes. This not only stops the cooking process but also makes peeling easier.
You can adjust the boiling process based on whether you want a creamy or fully cooked yolk, ensuring your Japanese egg sandwich has that rich flavor you crave.
Prepare the filling mixture
With your eggs peeled and ready, it’s time for the filling that ties everything together so deliciously.
- Mash it Up: Start by slicing the hard-boiled eggs in half and adding them to a mixing bowl. Use a fork to mash them into a fine mixture.
- Flavor Boost: Add 2 teaspoons of whole milk, 4 tablespoons of Kewpie Japanese mayonnaise, ½ teaspoon of white granulated sugar, ¾ teaspoon of salt, and a sprinkle of black pepper. Mix until everything is well combined, then chill the mixture in the refrigerator for about 10 minutes to allow the flavors to meld together.
- Optional Additions: If you’re feeling fancy, toss in finely chopped chives for an extra burst of flavor.
Assemble the sandwich
Now for the fun part—putting your Japanese egg sandwich together!
- Prep Your Bread: Take four slices of shokupan, ensuring you’ve trimmed off the crusts.
- Spread the Love: Generously butter one side of each bread slice. This creates a lovely barrier against moisture from the filling.
- Layer with Eggs: Place the medium-boiled egg halves face-down on two of the buttered slices, followed by the chilled egg mixture.
- Top It Off: Carefully place the other buttered slices on top to complete your sandwich stack.
Slice and prepare for serving
The final step brings the sandwich to life!
- Presentation Matters: Use a sharp knife to slice the sandwich diagonally. This simple step elevates the aesthetics and makes it easier to handle.
- Serve Fresh: While these sandwiches can be stored, they taste best enjoyed immediately after preparing them. Pair with a side of nibbles, like edamame or a light salad, and enjoy!
Your Japanese egg sandwich is now ready to be devoured! Perfect for lunch or a quick snack, these sandwiches reflect a delightful blend of simplicity and taste. Why not whip up a batch today? You’ll be glad you did!

Cooking Tips and Notes for Japanese Egg Sandwiches
Egg Boiling Tips for Different Textures
Achieving the perfect boiled egg is essential for your Japanese egg sandwich recipe. For creamy, medium-boiled eggs, simmer them for precisely 7 minutes and 30 seconds. Prefer a firmer texture? Leave the hard-boiled eggs in for another minute or so, arriving at 9 minutes total. Remember to shock them in an ice bath immediately to halt the cooking process — this helps with easy peeling too!
Best Bread Types to Use
Using the right bread can elevate your sandwich. I recommend shokupan, a soft Japanese milk bread known for its fluffy texture. You can also opt for brioche or other light sandwich breads if you don’t have shokupan on hand. Just ensure the bread is fresh and soft for that delightful bite!
