Ingredients You’ll Need
The beauty of this Japanese Egg Sandwich (Tamago Sando) Recipe lies in its simplicity. Each ingredient plays a key role—from the rich eggs to the sweet notes of sugar, and the velvety creaminess of Kewpie mayonnaise. These essentials ensure the sandwich is not only flavorful but also has that signature soft and creamy texture that makes it so memorable.
- 3 large eggs (50 g each without shell): The foundation for a creamy, fluffy egg filling packed with protein and flavor.
- ¼ tsp sugar: A subtle touch that balances the savoriness and enhances the natural sweetness of the eggs.
- ¼ tsp Diamond Crystal kosher salt: Perfectly seasons the eggs without overwhelming their delicate taste.
- ⅛ tsp freshly ground black pepper: Adds a mild warmth and depth to the flavor profile.
- 2 tsp milk: Keeps the egg salad smooth and tender, contributing to that melt-in-your-mouth feel.
- 2 Tbsp Japanese Kewpie mayonnaise: Creamy and slightly tangy, this mayo is the secret ingredient that makes this sandwich uniquely delicious.
- 4 slices shokupan (Japanese milk bread): Soft, sweet, and fluffy, this bread is light enough to let the egg shine.
- Salted butter: Adds richness and helps toast the bread slices to golden perfection when assembling.
How to Make Japanese Egg Sandwich (Tamago Sando) Recipe
Step 1: Hard Boil the Eggs Perfectly
Start by placing your 3 large eggs in a saucepan and covering them with water. Bring the water to a boil and let the eggs cook for 12 full minutes. The timing here is key; this ensures the yolks are fully set but still creamy enough to mash effortlessly. Once done, immediately transfer them to a bowl of iced water to stop the cooking process. This cooling step also makes peeling the eggs much easier and keeps the whites tender.
Step 2: Prepare the Egg Salad Filling
Peel the cooled eggs carefully and mash them with a fork until they reach a slightly chunky yet spreadable consistency. This texture is a wonderful balance between creamy and a touch of bite. Next, add the ¼ teaspoon sugar, ¼ teaspoon kosher salt, ⅛ teaspoon freshly ground black pepper, 2 teaspoons milk, and 2 tablespoons of Japanese Kewpie mayonnaise to the eggs. Mix everything together thoroughly until you achieve a smooth, luscious egg salad that carries a hint of sweetness and that signature tang from the Kewpie mayo.
Step 3: Prepare the Bread and Assemble the Sandwich
Take your four slices of soft shokupan bread and spread a thin layer of salted butter on each slice—this step keeps the sandwich rich and adds a slight crispness when pressed. On one buttered slice, generously spread a thick layer of the prepared egg salad. Top it with another slice, butter side down, to create a cozy sandwich pocket. Press the sandwich slightly between two plates or cutting boards to merge all the textures and enhance the softness. Finally, trim off the crusts for that classic tamago sando presentation and slice the sandwich in half for perfect, dainty servings.
How to Serve Japanese Egg Sandwich (Tamago Sando) Recipe

Garnishes
Though the Japanese Egg Sandwich (Tamago Sando) Recipe stands beautifully on its own, slightly embellishing it can elevate your experience. A simple sprinkle of finely chopped chives or a few strands of microgreens on top adds a refreshing color contrast and a hint of herbal brightness. For a bit of indulgence, a light dusting of togarashi seasoning introduces a subtle, spicy kick that pairs wonderfully with the creamy filling.
Side Dishes
This sandwich pairs beautifully with light, complementary sides. Try a crisp green salad tossed with a citrusy vinaigrette to cut through the richness, or a bowl of clear miso soup to keep things authentically Japanese. Pickled vegetables, such as daikon or cucumber tsukemono, lend a pleasant tang and crunch that contrast nicely with the softness of the sandwich. These sides maintain balance and add variety to your meal.
Creative Ways to Present
Once you master the traditional Japanese Egg Sandwich (Tamago Sando) Recipe, feel free to get creative. Try layering the egg salad with thin slices of avocado or cucumber for added texture and freshness. You could also cut your sandwich into bite-size squares for an elegant tea-time snack or party appetizer. Wrapping the sandwich halves in cute parchment paper or placing them in a bento box makes them ideal for a charming picnic or lunch on the go.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftover egg salad or sandwiches, store the egg salad in an airtight container in the refrigerator for up to two days. The sandwich itself is best eaten fresh but can be wrapped tightly in plastic wrap and kept in the fridge for a few hours if needed. Keep the bread from getting soggy by assembling just before eating whenever possible.
Freezing
Freezing is not recommended for the assembled Japanese Egg Sandwich (Tamago Sando) Recipe, as the texture of the bread and creamy egg salad can degrade when thawed. However, it’s possible to freeze the hard-boiled eggs peeled and stored separately for up to a month; just know the texture may change slightly after freezing.
Reheating
Since this sandwich is best enjoyed cold or at room temperature, reheating is not necessary and may lead to a less pleasant texture. If you prefer a warm sandwich, consider warming the bread slices lightly in a toaster before assembling with fresh egg salad.
FAQs
What makes Japanese Kewpie mayonnaise different from regular mayonnaise?
Kewpie mayonnaise is creamier, tangier, and slightly sweeter than regular mayonnaise, made with rice vinegar instead of distilled vinegar. This unique flavor perfectly complements the egg salad in the Japanese Egg Sandwich (Tamago Sando) Recipe, giving it its signature taste.
Can I use regular white bread if I don’t have shokupan?
While regular white bread can work in a pinch, shokupan’s soft, slightly sweet, and pillowy texture really elevates the sandwich. It’s worth seeking out if you want the authentic experience of the Japanese Egg Sandwich (Tamago Sando) Recipe.
How do I prevent the egg salad from being too dry or too wet?
Balance is key. Adding a little milk and the right amount of Kewpie mayonnaise creates a creamy but not runny consistency. Mash the eggs to your preferred texture while mixing ingredients gradually to get just the right spreadability.
Is this sandwich traditionally eaten cold or warm?
Japanese Egg Sandwich (Tamago Sando) Recipe is traditionally served cold or at room temperature. This allows the creamy egg salad to shine without melting or changing in texture.
Can I add other ingredients to the egg salad?
Absolutely! While the classic is divine on its own, feel free to incorporate finely chopped scallions, a pinch of curry powder, or even a hint of wasabi to personalize your sandwich experience.
