What is a Japanese Egg Sandwich?

Japanese egg salad sandwich also called tamago sando, is a Japanese spin on an egg salad sandwich. Japanese egg sandwiches are made with of hard-boiled eggs mixed with Japanese kewpie mayo softly sandwiched between two slices of Japanese milk bread or shokupan. This egg sando is incredibly popular in Japan. Normally, they are sold almost everywhere in Japan and for good reason, tamago sandwiches are so creamy and delicious. Anthony Bourdain described a Japanese salad sandwich as “Inexplicable Deliciousness.”

Ingredients

In comparison to the American-style sandwich, a tamago sando is much simpler. This tamago sando recipe only has three main ingredients—Hokkaido bread, Kewpie mayonnaise, and boiled eggs. It doesn’t have any added lettuce, tomato, etc.

  • Japanese Hokkaido Milk Bread: Japanese egg sandwiches use extremely soft and pillowy Hokkaido milk bread. This bread is subtly sweet, milky, and incredibly soft. You can make your own milk bread or pick some up at an Asian grocery store or bakery. However, you can also substitute this with regular white bread or brioche.
  • Eggs: Boiled eggs are the main ingredient for this egg sando. Importantly, make sure not to use old or expired ones!
  • Kewpie Mayonnaise: the essential ingredient for this tamago sando recipe. Kewpie mayo tastes light, subtly tangy, and rich and will make all the difference in flavor. You can find Kewpie mayo at most Asian grocery stores or online.
  • Milk: milk adds that extra creaminess to the tamago sandwich that ties everything together.
  • Salt: brings out the natural flavor of the eggs.
  • Sugar: that pinch of sweetness balances out the umami flavors of the Kewpie Mayonnaise.
  • Butter: make sure your butter is at room temperature. The butter flavors the bread and helps hold the egg sando together.

How to Make a Japanese Egg Sandwich

This Japanese egg sandwich recipe is so easy and simple to make! All you need to do is boil the eggs, mix the Japanese egg salad together, and assemble the tamago sando.

  1. Boil the eggs. Bring a medium pot filled halfway with water to a boil. Bring the water to a boil, then carefully add eggs in, with a spider strainer or slotted spoon. Simmer the eggs on medium heat for 9 minutes. Prepare an ice bath.
  2. Chill and peel the eggs. After 9 minutes, remove the eggs with a spider strainer or slotted spoon and immediately place the eggs into an ice bath to cool for at least 5 minutes. When the eggs are cool, gently peel the eggs.
  3. Separate the egg yolks. Cut the eggs in half separate the whites from the yolks and dice the egg whites.
  4. Mix the Japanese egg salad. In a small mixing bowl, using a fork mix together the egg yolks, kewpie mayonnaise, milk, sugar, salt, and pepper until smooth. Gently fold in the diced whites and green onion.
  5. Assemble the tamago sando. Butter the slices of bread then add the egg salad filling. Top with the other slice and press down gently. If you prefer, trim the crusts and slice them in half.

Tips for the Best Japanese Egg Sandwich

  • Use Milk Bread. You can either make your own Hokkaido milk bread at home or buy it sliced at your local Japanese grocery or bakery. If you cannot find milk bread substitute it with the softest white bread.
  • Mash the egg yolks separately first. Mixing the egg yolks first with the other ingredients ensures you’ll have a thoroughly combined, silky-smooth texture.
  • Add the milk! Be sure to add in milk for an extra creamy tamago sando.
  • Don’t skip the butter. It acts as a barrier between the eggs and the bread that prevents the tamago sandwich from getting soggy.

Storage Instructions

You can store the Japanese egg salad separated from the bread in an airtight container in the refrigerator for up to a week.

If the tamago sandwich is already assembled, you can wrap it and place it in an airtight container for up to 2 days.
