Ingredients You’ll Need
The beauty of this Japanese Egg Sandwich (Tamago Sando) Recipe lies in its simplicity.

You’ll find that just a handful of pantry staples come together to make something truly special.
- 4 large eggs: The star of the show, boiled to tender perfection for that ideal chunky-yet-creamy texture.
- 2 tablespoons Japanese mayonnaise (such as Kewpie): Adds an umami-rich creaminess that’s smoother and tangier than regular mayo.
- 1/2 teaspoon sugar: Balances savory notes by adding a gentle sweetness to the egg mixture.
- 1/4 teaspoon salt: Enhances all flavors subtly without overpowering.
- 1/8 teaspoon black pepper: Offers a mild warmth and a little bite.
- 4 slices soft white bread (milk bread or shokupan preferred), crusts removed: The fluffy and slightly sweet texture is essential for authenticity and comfort.
- 1 teaspoon softened butter (optional): Adds a slight richness and prevents the bread from becoming soggy.
How to Make Japanese Egg Sandwich (Tamago Sando) Recipe
Step 1: Boil the Eggs to Perfection
Start by bringing a small pot of water to a boil, then gently add the eggs to avoid cracking. Let them boil for exactly 10 minutes to achieve a firm yet moist yolk and whites that mash beautifully. Once done, immediately transfer the eggs into a bowl of ice water to cool completely—this step not only stops the cooking but also makes peeling a breeze.
Step 2: Prepare the Egg Mixture
Peel the cooled eggs and roughly chop or mash them in a bowl until you get a chunky but spreadable texture—the kind that clings perfectly to the bread. Next, stir in the Japanese mayonnaise, sugar, salt, and black pepper. Mixing these ingredients carefully ensures the egg salad reaches that delightful combination of creamy sweetness and savory seasoning that defines the Japanese Egg Sandwich (Tamago Sando) Recipe.
Step 3: Butter the Bread (Optional but Recommended)
If you want your sandwich bread to stay beautifully soft without becoming soggy, lightly spread softened butter on one side of each bread slice. This little touch adds a layer of richness and keeps the bread’s texture just right, making the final sandwich even more indulgent.
Step 4: Assemble Your Sandwich
Spread the egg mixture evenly onto two slices of the bread—don’t be shy with the filling, the fluffier, the better. Top with the remaining two slices of bread. Gently press the sandwiches to compact everything just enough, and trim the edges if needed for a clean presentation. Cut into halves or thirds, and your Japanese Egg Sandwich (Tamago Sando) Recipe is ready to brighten any mealtime.
How to Serve Japanese Egg Sandwich (Tamago Sando) Recipe

Garnishes
This sandwich is wonderfully simple on its own, but adding a sprinkle of finely chopped chives, a few sesame seeds, or even a pinch of shichimi togarashi can bring a subtle pop of color and an extra layer of flavor that keeps every bite exciting and fresh.
Side Dishes
Pair your Tamago Sando with a crisp green salad or a refreshing bowl of miso soup to balance the richness of the sandwich. Pickled vegetables like takuan or a light seaweed salad also complement the creamy egg filling beautifully and add a bright, textural contrast that makes the meal feel complete.
Creative Ways to Present
Make your serving extra special by using cookie cutters to shape the sandwiches into fun forms like hearts or stars, perfect for entertaining or lunchboxes. Alternatively, stack several Tamago Sando sandwiches cut into small blocks on a platter for an inviting party appetizer that guests will adore.
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftover sandwiches, wrap them tightly in plastic wrap or keep them in an airtight container in the refrigerator. They maintain their flavor best when eaten within a day, as the bread can start to lose its softness and the filling may become a bit watery.
Freezing
Freezing is not typically recommended for the Japanese Egg Sandwich (Tamago Sando) Recipe because the delicate texture of the milk bread and creamy egg mix can suffer, becoming mushy or dry once thawed. For best results, enjoy it fresh or refrigerate briefly.
Reheating
This sandwich is traditionally served chilled or at room temperature. If you prefer it a bit warmer, gently warm the egg mixture before assembling but avoid microwaving the assembled sandwich to keep the bread’s texture flawless.
FAQs
Can I use regular mayonnaise instead of Japanese mayonnaise?
Yes, you can! Regular mayonnaise works well in a pinch, but Japanese mayonnaise like Kewpie has a richer, slightly sweeter flavor and creamier texture that makes a noticeable difference in authentic taste.
What kind of bread works best for Tamago Sando?
Japanese milk bread, also called shokupan, is ideal because it’s incredibly soft, slightly sweet, and has a tender crumb that complements the fluffy egg filling perfectly. If you can’t find it, any soft white bread without a crust will do.
How long can I store the egg sandwich in the fridge?
For optimal freshness and texture, it’s best to consume the sandwich within 24 hours. After that, the bread may become soggy and the egg salad less vibrant.
Can I make the egg mixture in advance?
Absolutely! Preparing the egg mixture a few hours ahead is fine and often recommended as it allows the flavors to blend beautifully. Just keep it refrigerated until you’re ready to assemble your sandwich.
Is this recipe suitable for vegetarians?
Yes, the Japanese Egg Sandwich (Tamago Sando) Recipe is vegetarian-friendly since it contains no meat or fish, making it a delicious choice for a satisfying plant-based meal or snack.
