Boil the eggs to perfection
To really nail down the flavor and texture of our Japanese Egg Sandwich, it all begins with perfectly boiled eggs. You’ll want to boil 6 large eggs for hard-boiled perfection and optionally, one large egg for that luxurious medium-boiled experience.
-
Boil the hard-boiled eggs: Place the eggs in a pot filled with water, and bring it to a rolling boil over medium-high heat. Let them boil for exactly 9 minutes.
-
Chill in an ice bath: As soon as they are done, transfer the boiled eggs to a bowl filled with ice water for about 2 minutes. This will help with peeling and stop the cooking process.
-
For the medium-boiled egg: After 7 minutes and 30 seconds, remove one egg and let it cool in the ice bath. This will give you that creamy, gooey yolk that makes this dish so special.
Prepare the egg filling
Next up in this Japanese egg sandwich recipe is the filling, which is a creamier delight than you might think.
-
Mash it up: Peel the hard-boiled eggs and cut them in half. In a mixing bowl, mash them with a fork until you have fine pieces.
-
Make it creamy: Stir in 2 teaspoon of whole milk, 4 tablespoon of Kewpie mayonnaise, ½ teaspoon sugar, ¾ teaspoon salt, and ¼ teaspoon black pepper. This combination will bind everything together and elevate the taste.
-
Chill: Cover the mixture and pop it in the fridge for around 10 minutes. It allows the flavors to meld beautifully.
Assemble the sandwich with precision
Now comes the fun part—assembling your sandwich!
-
Prep the bread: Take 4 slices of shokupan (Japanese soft bread) and cut off the crusts. Spread butter on one side of each slice to add richness.
-
Layering: Place the medium-boiled egg face-down on two slices. Surround it with your chilled egg filling, creating a soft cushion for that precious egg.
-
Top it off: Lay the remaining slices of shokupan on top and press down gently. Now you have your beautiful sandwich ready.
Slice and serve with style
The last step is all about presentation and enjoyment.

Variations on the Japanese Egg Sandwich
Add turkey bacon for a protein boost
Looking to elevate your Japanese egg sandwich recipe? Consider adding turkey bacon for a tasty protein kick! Its savory flavor pairs beautifully with the creamy egg filling. Just crisp it up in a skillet and layer it within your sandwich for an added crunch and savory goodness. Not only does this variation enhance the nutrition of your sandwich, but it also gives you that satisfying texture contrast that makes each bite delicious.

What is Kewpie mayonnaise, and why should I use it?
Kewpie mayonnaise is a uniquely delicious Japanese mayonnaise that is richer and creamier than regular mayonnaise, thanks to its use of only egg yolks and a hint of rice vinegar. This gives it a subtly sweet flavor profile that perfectly complements the filling in a Japanese egg sandwich recipe. If you can find it at your local grocery store or online, it’s definitely worth using for that authentic taste!
Can I make this sandwich ahead of time?
Absolutely! You can assemble your Japanese egg sandwich and keep it in the refrigerator for a few hours before serving. Just make sure to wrap it tightly in plastic wrap to maintain freshness. For the best texture, it’s better to put it together close to meal time if you plan on eating it the next day.

While shokupan is a traditional Japanese milk bread that offers a soft and fluffy texture, you can substitute it with other bread types. Look for:
- White sandwich bread: Soft and versatile.
- Whole wheat bread: For a healthier option.
- Brioche or challah: These will add a rich, buttery flavor.
