Tamago Sando (japanese Egg Sandwich)

This protein packed tamgo sando recipe (Japanese egg salad sandwich) has a triple dose of eggs, packed with medium boiled eggs, egg salad, and mayonnaise. - 1

I’ve always had a soft spot for egg sandwiches, but Japan’s tamago sando hits differently. Imagine hearty, tender chunks of boiled eggs gently folded into a silky, savory-sweet egg salad, all tucked neatly between two pillowy slices of shokupan (Japanese milk bread). Although Japan’s love affair with bread started centuries ago, sandwiches didn’t become popular until the country reopened to Western influences in the mid-1800s. Fast-forward to today, and you’ll find Japanese egg sandwiches everywhere-from trendy café menus to corner konbini (convenience stores). After my recent Japanese egg sandwich taste test comparing offerings from 7-Eleven, Family Mart, and Lawson, I was inspired to create a homemade version, combining my favorite elements into one perfect egg salad sandwich.

Why This Recipe Works:

My favorite konbini-style tamago sando recipe blends creamy egg salad with hearty chunks of boiled eggs. To recreate this delightful contrast of textures, I tuck halved boiled eggs into the sandwich along with a flavorful egg salad to hold everything together.
The secret to an authentic Japanese egg salad sandwich lies in using Japanese mayonnaise, like Kewpie mayo. Its savory and subtly sweet profile effortlessly balances the richness of the eggs, adding depth while maintaining a silky, indulgent mouthfeel.
While traditional Japanese egg sandwiches typically skip crunchy additions like onions, pickles, or celery, I like adding a dash of onion powder to boost flavor without disrupting the delicate, velvety texture of the creamy filling.

Ingredients

Japanese mayonnaise - Best known under the Kewpie brand, the Japanese version of mayo has become a staple ingredient in Japan. Its creamy texture is perfectly balanced by a subtle sweetness and gentle tang, giving it a homemade taste that’s richer and smoother than American mayonnaise. It’s the key to achieving the authentic flavor of a classic tamago sando.
Sandwich bread (shokupan) - Shokupan(食パン) is a Japanese white bread that’s perfect for these egg sandwiches, thanks to its uniquely fluffy yet firm and slightly chewy bite. Baked in covered pans, it has a distinctive square shape and a subtly sweet flavor that complements the creamy egg filling. If you can’t find shokupan, any soft bread such as white sandwich bread or brioche can work as a substitute.
Eggs - Medium-boiled eggs (7-8 minutes) provide the perfect balance between structure and creaminess. Soft-boiled eggs will also work, but it will result in a softer filling do to the runny egg yolks. To create a contrast of textures, I like including both halved and chopped eggs.
Onion powder - While traditional Japanese egg salad sandwiches usually avoid crunchy ingredients, a small pinch of onion powder adds extra flavor without disturbing the silky texture of the egg salad. This was inspired by the FamilyMart egg sandwich.
Dijon mustard - A touch of mustard adds a gentle tang and complexity to the egg salad, balancing out the richness of the eggs and mayonnaise without overpowering the sandwich.
White pepper - White pepper offers a delicate heat and aroma, enhancing the overall flavor of the sandwich while remaining mild enough to preserve the smooth, creamy texture characteristic of a great tamago sando. Black pepper will also work.

How to Make Tamago Sando

Start by medium-boiling your eggs; if you don’t already have a method, I have a perfect boiled eggs tutorial that’ll show you how to do it. Slice one boiled egg in half and set it aside; this will add a satisfying texture to your sandwich.

Roughly chop the remaining eggs and place them into a bowl with the Japanese mayonnaise, Dijon mustard, white or black pepper, onion powder, and a pinch of salt. Stir the mixture together until smooth and creamy.

To assemble your tamago sando, lay two slices of Japanese white bread on your workspace. Arrange the egg halves on one piece of bread, pointing the tapered ends toward opposite corners-this ensures each sandwich half will showcase a beautiful cross-section when cut.

Spoon the creamy egg salad mixture generously over the halved eggs, gently spreading it to fill the edges evenly. Place the second slice of bread on top, pressing gently around the edges to mold it around the filling. To make it easier to slice, I recommend wrapping the sandwich tightly in plastic wrap and chilling it for 30 minutes in the refrigerator.

If you prefer a more classic Japanese egg salad sandwich presentation, trim off the crusts carefully before slicing diagonally.

Nutrition Facts

Tamago Sando (卵サンド) literally means “egg sandwich” in Japanese, and it refers to the Japanese version of the egg salad sandwich. Although both sandwiches and egg salad are Western inventions, they have evolved into somethinguniquely Japanese. There are a couple of variations, including one that’s made by stuffing a Japanese omelette into a sandwich , but this one is for a more traditional egg salad made with boiled eggs and mayo.

Japanese egg salad sandwiches have three key differences from their Western counterparts. The first is that the sandwich is all about the egg, so there typically aren’t any vegetables such as onions, celery, or pickles included. The second is that the eggs are mixed with Japanese-style mayonnaise. The third is that the egg is sandwiched between slices of Japanese sandwich bread.

Convenience stores, known as konbini in Japan, are basically small supermarkets with a large selection of prepared foods. The three major konbini chains are 7-Eleven, FamilyMart, and Lawson, and they each do their take on the egg sandwich. Riding on the coattails of another konbini favorite, katsu-sando , Japanese-style egg sandwiches have picked up a following outside Japan, which I’m guessing is why you’re here😉.
