Step‑by‑Step Instructions for Japanese Egg Sandwich
Step 1: Prepare the Ice Bath
Start by preparing an ice bath to cool down the eggs after boiling. Fill a medium bowl with ice and water, ensuring there’s enough ice to chill the eggs quickly. Meanwhile, fill a medium pot with water and bring it to a rolling boil over high heat. This ice bath will stop the cooking process and make peeling the eggs effortless.
Step 2: Boil the Eggs
Gently lower the fresh organic eggs into the boiling water using a slotted spoon to avoid cracking. For medium soft-boiled eggs, cook them for exactly 7 minutes for that perfect creamy center. If you prefer hard-boiled eggs, allow them to cook for about 10 minutes. Keep an eye on the timer to ensure the perfect doneness for your Japanese egg sandwich.
Step 3: Cool and Peel the Eggs
Once the eggs are done cooking, immediately transfer them into the ice bath using the slotted spoon. Let them sit for about 2 minutes to cool off and stop the cooking process. After chilling, gently tap the eggs on a hard surface and peel them under running water to ensure you don’t miss any shell pieces, making them ready for the egg salad.
Step 4: Prepare the Egg Salad
In a mixing bowl, mash the peeled eggs using a fork until they are broken down but still slightly chunky. Add sugar, salt, ground black pepper, and Japanese mayonnaise to the eggs. If desired, pour in a little milk for creaminess. Mix well until all the ingredients are fully combined, creating a delicious filling for your Japanese egg sandwich.
Step 5: Assemble the Sandwich
Take two slices of soft Japanese milk bread and spread unsalted butter on one side of each slice for added richness. On the unbuttered side of one slice, generously spread the creamy egg salad, ensuring even coverage. Place the second slice, buttered side down, on top of the egg salad and press gently to adhere the layers together, forming your delightful Japanese egg sandwich.
Step 6: Trim and Serve
Using a sharp knife, carefully trim the crusts off the sides of the sandwich for a beautiful presentation. Cut the sandwich in half diagonally for easy handling. Serve immediately for the freshest taste, or wrap tightly in plastic wrap for a quick on-the-go lunch option. Enjoy the comforting flavors of your perfectly crafted Japanese egg sandwich!

Make Ahead Options
These Japanese Egg Sandwiches are perfect for meal prep enthusiasts looking to save time during busy weeknights! You can prep the egg salad (mashing the boiled eggs with sugar, salt, pepper, and Japanese mayonnaise) up to 24 hours in advance. Store the egg salad in an airtight container in the refrigerator to maintain its creamy texture. As for the sandwiches, assemble them the day you’re ready to serve for the freshest taste, but they can be wrapped tightly and refrigerated for up to 2 days. When you’re ready, simply cut the sandwiches, trim the crusts, and you’ll have a delicious, ready-to-enjoy meal that’s just as tasty as when freshly made!
