Japanese Egg Sandwich

Japanese Egg Sandwich

A Japanese Egg Sandwich, or Tamago Sando, is a creamy and comforting dish made with soft-boiled eggs, Japanese mayonnaise, and fluffy milk bread. It’s a beloved Japanese convenience store classic known for its silky texture and delicate balance of flavors.

Ingredients

  • 6 large eggs
  • 1/4 teaspoon sugar
  • 1/4 teaspoon salt
  • 1/4 teaspoon ground black pepper
  • 1 to 2 teaspoons milk or plant milk (optional)
  • 4 tablespoons Japanese mayonnaise
  • 4 slices Japanese milk bread
  • 2 tablespoons unsalted butter, softened
  • Chives, sliced (optional garnish)

Instructions

  1. Prepare an ice bath in a large bowl.
  2. Bring a pot of water to boil and gently lower in the eggs. Boil for 7 minutes for soft-boiled or 10 minutes for hard-boiled eggs.
  3. Turn off the heat and let eggs sit for 1 minute, then transfer immediately to the ice bath for 2 minutes to cool slightly.
  4. Peel the eggs while still warm and place them in a bowl.
  5. Mash the eggs with a fork, adding sugar, salt, and pepper. Continue mashing until the pieces are small but not fully smooth.
  6. Add Japanese mayonnaise and mix well. If using hard-boiled eggs, add milk for creaminess. Adjust seasoning to taste.
  7. Spread butter evenly on one side of each bread slice.
  8. Spread egg salad over one slice, then top with another slice, buttered side down.
  9. Press gently, trim off crusts, and cut the sandwich in half.
  10. Garnish with chives if desired and serve immediately.

Notes

  • Use high-quality organic eggs for the best flavor and texture.
  • Japanese mayonnaise (like Kewpie) creates a richer, creamier taste than regular mayonnaise.
  • Use milk bread (shokupan) for authentic texture; substitute with soft white bread if unavailable.
  • For storage, wrap the sandwich tightly and refrigerate for up to 2 days.
