Step‑by‑Step Instructions for Japanese Egg Sandwich
Step 1: Prepare Ice Bath
Fill a large mixing bowl with ice and cold water to create an ice bath. This will help cool the boiled eggs quickly and make peeling easier. Set the bowl aside for when the eggs are finished cooking, ensuring you’re ready to tackle the next step efficiently.
Step 2: Boil Eggs
In a medium-sized pot, bring enough water to a rolling boil. Carefully lower in the 6 large organic eggs and cook for 7 minutes for medium soft-boiled eggs or 10 minutes for hard-boiled eggs. Once the timer goes off, the eggs’ whites should be set but the yolks still slightly creamy for that perfect texture in your Japanese Egg Sandwich.
Step 3: Chill Eggs
After boiling, use a slotted spoon to transfer the eggs into the ice bath. Allow them to chill for about 2 minutes until they are cool enough to handle. This step not only stops the cooking process but also helps in peeling the eggs smoothly while they are still lukewarm, hinting at that creamy delight waiting for you.
Step 4: Make Egg Salad
Once peeled, place the eggs in a mixing bowl and use a fork to mash them until you reach a desired coarseness. Add 1/4 teaspoon sugar, 1/4 teaspoon salt, and 1/4 teaspoon ground black pepper to the eggs. Then, mix in 4 tablespoons of Japanese mayonnaise and 1 to 2 teaspoons of milk if you desire a creamier texture. Adjust seasoning to taste as you blend.
Step 5: Assemble Sandwich
Take 4 slices of Japanese milk bread and spread 1 tablespoon of softened butter on one side of each slice. Spoon a generous amount of your creamy egg salad onto the unbuttered side of two bread slices, creating that luscious filling for your Japanese Egg Sandwich. Top with the remaining slices, buttered side facing up, and press down gently.
Step 6: Serve
Using a sharp knife, carefully trim the crusts from the sandwiches to enhance their presentation. Cut each assembled sandwich in half diagonally to reveal the creamy filling inside. Serve your delicious Japanese Egg Sandwiches immediately for the best flavor experience, or wrap them tightly to enjoy later.

How to Store and Freeze Japanese Egg Sandwich
Fridge: Wrap your Japanese Egg Sandwich tightly in plastic wrap or place it in an airtight container. It will stay fresh for up to 2 days, preserving its creamy goodness.
Freezer: If you want to store the sandwich for a longer period, wrap it securely and freeze for up to 1 month. Thaw in the fridge overnight before serving.
Reheating: For best results, gently reheat in a microwave or enjoy it at room temperature. Avoid freezing the egg salad separately, as this can affect the texture.
Assembling Tips: If you’re making these sandwiches in advance, consider storing the egg salad separately and assembling the sandwich just before eating to maintain freshness.
Make Ahead Options
These flavorful Japanese Egg Sandwiches are perfect for busy home cooks looking to save time during the week! You can prepare the egg salad up to 24 hours in advance by cooking and chilling the eggs just as the recipe directs. Simply mash the cooled eggs and mix in the sugar, salt, pepper, and mayonnaise; store the egg salad in an airtight container in the refrigerator. To maintain freshness, assemble the sandwich with the egg salad and bread no more than 2 hours before serving. This way, the sandwich stays soft and delicious, allowing you to enjoy a quick, homemade meal any time!
