Ingredients You’ll Need

What makes this Japanese Egg Sandwich so special is how simple the ingredients are, yet each one plays a vital role in creating the perfect balance of flavors and textures. From the creamy mayo to the fluffy eggs, each element is essential to bring out that authentic taste and tender mouthfeel.

• 6 large eggs: The star of the dish, providing creamy texture and rich flavor once softly boiled and mashed.
• 1/4 teaspoon sugar: A small pinch to add a subtle sweetness that rounds out the savory notes perfectly.
• 1/4 teaspoon salt: Enhances the natural flavor of the eggs and ties the whole filling together.
• 1/4 teaspoon ground black pepper: Adds a gentle warmth and depth to the egg mixture.
• 1-2 teaspoons milk or plant milk (optional): Used to add extra creaminess, especially if you prefer your boiled eggs fully hard.
• 4 tablespoons Japanese mayonnaise: Creamy, slightly tangy, and richer than regular mayo—key to authentic taste and luscious texture.
• 4 slices Japanese milk bread: Soft, fluffy, and slightly sweet bread that is the perfect vessel for this delicate egg filling.
• 2 tablespoons unsalted butter, softened: Adds an indulgent richness and helps keep the sandwich moist.
• Chives, sliced (optional): For a fresh, mild oniony note and attractive garnish.

How to Make Japanese Egg Sandwich (Tamago Sando) Recipe

Step 1: Prepare an Ice Bath

Start by filling a large bowl with ice water; this will be crucial to stop the eggs from cooking further once boiled. The ice bath keeps the yolk perfectly tender and ensures easy peeling later on.

Step 2: Boil the Eggs

Bring a medium-sized pot of water to a rolling boil. Carefully lower the eggs using a ladle to avoid cracking. Boil for 7 minutes if you want medium-soft boiled eggs with a slightly creamy yolk, or 10 minutes if you prefer fully hard-boiled eggs perfect for sheer creaminess.

Step 3: Cool and Peel the Eggs

Immediately transfer the eggs into the ice bath and let them sit for about 2 minutes. This halts the cooking process and makes peeling a breeze, leaving you with smooth shells that come off effortlessly.

Step 4: Mash the Eggs

Peel the eggs and transfer them into a large mixing bowl. Using a fork, mash them gently but thoroughly until you reach a soft, chunky consistency that is just right for spreading.

Step 5: Add Seasonings and Mayo

Now for the magic touch: add sugar, salt, ground black pepper, and the creamy Japanese mayonnaise. If you’ve boiled your eggs fully hard, add 1-2 teaspoons of milk or plant milk to make the mixture more luscious and easy to spread. Mix everything well until combined.

Step 6: Taste and Adjust

Give your egg salad a quick taste test to check the balance of seasoning. Adjust the salt, pepper, or mayo as preferred. The goal is a mellow, slightly sweet, and creamy filling that shines on its own.

Step 7: Butter the Bread

Take each slice of Japanese milk bread and spread about half a tablespoon of softened unsalted butter evenly. This not only adds moisture and richness but also creates a soft barrier so the bread stays fresh longer.

Step 8: Layer the Egg Salad

Generously spread the prepared egg filling over one slice of buttered bread. The thickness is up to you, but I love a good, hearty layer for that perfect bite.

Step 9: Assemble and Press

Place the other slice of bread on top with the buttered side facing down. Gently press the sandwich to make sure everything sticks together nicely without squishing out the filling.

Step 10: Cut and Garnish

Slice off the crusts carefully for that iconic Japanese sandwich look, then cut the sandwich in half or into smaller rectangles. If you’d like, sprinkle sliced chives for a pop of color and a mild fresh note right on top before serving.

How to Serve Japanese Egg Sandwich (Tamago Sando) Recipe

Garnishes

While this sandwich is delicious all on its own, adding a little sprinkle of chopped chives or even a dash of togarashi (Japanese chili powder) can elevate each bite with freshness or a touch of heat. A light dusting of paprika can also add color and flavor without overwhelming the creamy filling.

Side Dishes

Pair your Japanese Egg Sandwich with simple, crisp sides like a fresh green salad dressed with a light sesame vinaigrette, a handful of crunchy pickles, or a bowl of miso soup. These accompaniments accentuate the sandwich’s richness and add textural variety to your meal.

Creative Ways to Present

If you want to impress guests or elevate your lunchbox game, try cutting the sandwiches into bite-sized cubes and securing them with pretty toothpicks for party appetizers. Another fun idea is layering some thinly sliced cucumber or avocado inside for extra crunch and creaminess. Serving them on a colorful plate with a small dipping bowl of soy mayo adds a playful twist!

Make Ahead and Storage

Storing Leftovers

If you have any sandwiches left over, wrap each one tightly in plastic wrap to keep the bread from drying out. Store them in the refrigerator for up to 2 days. Eating them within this window ensures the egg filling remains fresh and creamy without the bread becoming soggy.

Freezing

This sandwich is best enjoyed fresh, so freezing isn’t recommended since the bread and egg salad will lose their ideal texture upon thawing. For the freshest experience, try to prepare only what you plan to eat within a day or two.

Reheating

Reheat your sandwich slightly by placing it in a low oven or toaster oven wrapped in foil to gently warm without drying. Avoid microwaving as it can make the bread tough and the filling rubbery. Serving it at room temperature is actually the best way to enjoy its creamy texture.

FAQs

Can I use regular mayonnaise instead of Japanese mayonnaise?

You can, but Japanese mayonnaise is creamier and slightly sweeter, which really elevates the sandwich to authentic flavors. If you only have regular mayo, consider adding a tiny bit of sugar to mimic that subtle sweetness.

What type of bread is best for Japanese egg sandwiches?

Japanese milk bread (shokupan) is the traditional choice because of its soft, fluffy texture and slightly sweet taste. If unavailable, use any soft white bread that is tender and not too dense.

How can I make the eggs creamier?

For a creamier texture, mash the eggs thoroughly and mix in a bit of milk or plant milk along with the mayonnaise. Using medium-soft boiled eggs also adds natural creaminess to the filling.

Is it possible to make this recipe vegan?

While the classic Japanese Egg Sandwich relies on eggs and mayonnaise, you can experiment with mashed tofu or chickpeas, vegan mayo, and plant-based milk bread to create a delightful plant-based version.

How long can I keep the egg salad filling before assembling?

You can prepare the egg salad filling up to one day in advance and store it in an airtight container in the fridge. Make sure to mix well before spreading to keep it creamy and flavorful.
