Ingredients You’ll Need
This recipe relies on a handful of straightforward ingredients, each playing an important role in creating that perfect balance of flavor, texture, and creaminess. The key is how these simple components come together to elevate the humble egg sandwich into something truly irresistible.
- 3 large eggs (50 g each w/o shell): The star of the show, cooked just right to create a tender, fluffy egg filling.
- ¼ tsp sugar: Adds a subtle sweetness that enhances the egg’s delicate flavor without overpowering.
- ¼ tsp Diamond Crystal kosher salt: Perfectly seasons the egg filling for a well-rounded taste.
- ⅛ tsp freshly ground black pepper: Just a touch to give a mild spicy warmth against the creamy backdrop.
- 2 tsp milk: Helps make the egg mixture extra soft and luscious.
- 2 Tbsp Japanese Kewpie mayonnaise: Creamy and slightly tangy, this mayo is essential for that authentic tamago sando texture.
- 4 slices shokupan (Japanese milk bread): Soft, fluffy bread with a hint of sweetness that perfectly cradles the filling.
- Salted butter: Adds a rich flavor and prevents the bread from drying out while providing balance to the egg salad.
How to Make Japanese Egg Sandwich (Tamago Sando) Recipe
Step 1: Cook the Eggs to Perfection
Begin by placing the eggs in a saucepan, covering them with water, and bringing it to a boil. Once boiling, reduce the heat slightly and let the eggs cook for 12 minutes to achieve a firm but tender yolk. Immediately transfer them to iced water to stop the cooking process and make peeling easier. Once peeled, mash the eggs gently with a fork to create a fluffy base for the filling.
Step 2: Make the Creamy Egg Salad
To your mashed eggs, add sugar, kosher salt, freshly ground black pepper, milk, and Kewpie mayonnaise. These ingredients blend beautifully to create a taste that’s creamy, slightly sweet, savory, and just a little tangy. Mix it all gently until well combined but still slightly textured to keep that inviting bite.
Step 3: Prepare the Bread and Assemble
Spread salted butter on each slice of the Japanese milk bread—this simple step locks in moisture and adds richness. Then, spread the luscious egg salad generously over one buttered slice. Top it with another slice, buttered side down, to form a sandwich. Press slightly by placing the sandwich between two plates or your hands to compact it gently.
Step 4: Final Touches and Serve
Cut off the crusts for that iconic, neat tamago sando shape, and slice the sandwich in half. The neat squares with the creamy filling peeking through create an inviting appearance that matches the sandwich’s delightful taste. Serve immediately for the best eating experience.
How to Serve Japanese Egg Sandwich (Tamago Sando) Recipe

Garnishes
While the traditional Japanese Egg Sandwich (Tamago Sando) Recipe shines on its own, you can add a sprinkle of finely chopped fresh chives or a dash of shichimi togarashi for a mild kick and a pop of color. A few delicate lettuce leaves inside can also add a refreshing crispness without overshadowing the creamy egg filling.
Side Dishes
This sandwich pairs wonderfully with light, crisp sides such as a simple green salad with a citrus vinaigrette or a bowl of miso soup to complete a classic Japanese meal. For a casual snack, some crunchy pickled vegetables or edamame will balance the richness beautifully.
Creative Ways to Present
For a charming brunch or tea party, cut the sandwiches into cute triangles or mini fingers and arrange them on a pretty platter. You can layer the egg salad with thin slices of avocado or sprinkle toasted sesame seeds over the filling to add texture and visual interest. Wrapping them carefully in parchment paper tied with a ribbon makes for a delightful packed lunch presentation.
Make Ahead and Storage
Storing Leftovers
If you have any leftover Japanese Egg Sandwich (Tamago Sando) Recipe, wrap them tightly in plastic wrap and keep them in the refrigerator. Because of the mayonnaise and tender bread, it’s best eaten within the same day or up to the next day to preserve freshness and texture.
Freezing
Freezing is not recommended for this sandwich because the delicate bread and creamy egg filling will suffer in texture once thawed. For the freshest experience, enjoy it fresh or store only briefly in the fridge.
Reheating
Because the sandwich is best enjoyed cold or at room temperature, reheating is not ideal. If you prefer your sandwich slightly warmer, take it out of the refrigerator about 30 minutes before serving to let it soften naturally.
FAQs
Can I use regular mayonnaise instead of Kewpie mayonnaise?
Yes, you can use regular mayonnaise, but Kewpie has a slightly sweeter and richer flavor that gives the Tamago Sando its signature taste. If you want to get close to the authentic profile, consider adding a little rice vinegar or a touch of sugar to regular mayo.
What kind of bread is best for this sandwich?
Shokupan, or Japanese milk bread, is ideal because of its soft, fluffy texture and mild sweetness. If unavailable, a high-quality, soft white sandwich bread with a tender crumb works well as a substitute.
How do I make the eggs creamy without making them too runny?
Cooking the eggs for exactly 12 minutes ensures they are firm but not rubbery. Mashing them with just enough mayo and milk creates a creamy, spreadable texture without excess moisture that would make the sandwich soggy.
Can I add other ingredients to the egg filling?
Absolutely! Some people like to add finely chopped green onions, Japanese pickles, or even a sprinkle of furikake seasoning for extra flavor. Just keep additions light so they complement the delicate egg salad instead of overpowering it.
Is this sandwich suitable for kids?
Definitely! The mild, creamy flavors and soft bread make it a favorite for children and adults alike. It’s a gentle way to introduce kids to Japanese flavors in a familiar sandwich format.
Final Thoughts
I can’t recommend the Japanese Egg Sandwich (Tamago Sando) Recipe highly enough if you’re searching for a simple yet extraordinary sandwich experience. With just a few ingredients and minimal prep, it brings together comforting creaminess, subtle sweetness, and a hint of savory goodness that truly feels like a warm hug in every bite. Once you try it, this sandwich will no doubt become a cherished staple in your kitchen too.
