The importance of shokupan bread
No Japanese egg sandwich would be complete without soft, fluffy shokupan (Japanese milk bread). Its light and airy texture complements the egg filling perfectly, making each bite melt in your mouth. This type of bread is usually slightly sweet, making it a delightful base for the savory filling.

Preparing Japanese Egg Sandwich
Creating a delightful Japanese Egg Sandwich (Tamago Sando) is a fantastic way to bring a touch of Japan to your kitchen. This creamy, flavorful delicacy isn't just perfect for lunch—it can also be enjoyed as a snack any time of day. Let's dive into the steps that make this sandwich come alive!
Boil the eggs perfectly
The first step in preparing your Japanese Egg Sandwich is to achieve perfectly boiled eggs. Place three large eggs in a medium saucepan and add enough water to cover them by about an inch. Bring the water to a boil over medium heat. Once it reaches a rolling boil, allow the eggs to cook for 12 minutes. This timing ensures a firm yet creamy yolk that’s essential for a rich egg salad. After the timer goes off, it’s crucial to stop the cooking process. Transfer the eggs to an ice water bath until they're completely cool—this makes peeling a breeze.
Prepare the egg salad mixture
Once your eggs are peeled, transfer them to a bowl and start mashing them with a fork. The goal here is to create small, uniform pieces of egg whites and yolk. To elevate the flavor, mix in ¼ teaspoon of sugar, ¼ teaspoon of kosher salt, and ⅛ teaspoon of freshly ground black pepper. For that signature creaminess, add in 2 teaspoons of milk and 2 tablespoons of Japanese Kewpie mayonnaise. Kewpie is famous for its umami-rich flavor, and it really makes this egg salad shine. Give everything a good stir and taste it—feel free to adjust the seasoning to your liking.
Assemble the sandwich
Next up, we’re going to bring it all together! Lay out four slices of shokupan (Japanese milk bread) and spread a thin layer of salted butter on each slice. This adds a touch of richness to your sandwich. Spoon the fluffy egg salad onto two slices of bread, making sure to spread it evenly. Then, gently place the other buttered slice on top, buttered side down.
Compress and cut the sandwiches
To ensure the ingredients meld beautifully, place the sandwiches between two plates and apply a little pressure for about 5 minutes. This step is crucial; it helps create that classic compactness that makes the Japanese Egg Sandwich so enjoyable. Once you’ve let them sit, it’s time to trim the crusts off the bread. But remember, don’t toss those crusts! Instead, repurpose them into crunchy Shokupan Crust Rusks for a delightful snack later.
Final presentation
Finally, cut your sandwiches in half diagonally for a lovely presentation. Serve them immediately on a clean plate, perhaps with a side of pickles or a refreshing salad. The combination of buttery flavors, creamy egg salad, and soft bread makes this Japanese Egg Sandwich a culinary delight. Not only does it look appealing, but every bite takes you straight to Japan!
By following these simple steps, you're well on your way to mastering this delicious sandwich. Whether it's part of a picnic or a quick lunch, it’s bound to impress.

Cooking notes for Japanese Egg Sandwich
Tips for achieving the perfect egg salad consistency
For an irresistible Japanese egg sandwich, the key lies in the egg salad's texture. Aim for a creamy yet slightly chunky consistency by mashing the eggs with a fork rather than a knife. This retains some of the egg white's bite while ensuring the yolk is smooth. Adding Kewpie mayonnaise gives it that extra creamy flavor we all crave, but don’t forget to taste and adjust the seasoning!
Storing leftovers to maintain freshness
If you have leftover sandwiches, you can easily keep them in an airtight container in the fridge for up to 2 days. To prevent the bread from getting soggy, consider separating the egg salad and bread until you’re ready to enjoy. This way, your tamago sando stays delightful—just like your first bite!

Pairing with fresh salads
Enhance your Japanese egg sandwich experience with a vibrant, fresh salad. Light leafy greens, such as arugula or spinach, add a peppery crunch that beautifully contrasts the creamy egg filling.

Consider adding seasonal vegetables like cherry tomatoes or cucumber slices for extra freshness!
Serving with pickles or chips
For those craving a bit of crunch, serve your tamago sando alongside crispy pickles or your favorite chips.
