Ingredients (Makes 4 Sandwich Halves)

Main Ingredients

  • 4 slices Japanese Shokupan (milk bread)
  • 4 large eggs
  • 4 tablespoons Japanese mayonnaise (such as Kewpie-style mayonnaise)
  • 1 teaspoon unsalted butter (softened)
  • ½ teaspoon Dijon mustard (optional)
  • Salt, to taste
  • Freshly ground black pepper, to taste

Optional Additions

  • Chopped chives
  • Finely chopped parsley
  • Lettuce leaves
  • Thin cucumber slices
  • Paprika for garnish

Kitchen Equipment

  • Saucepan
  • Mixing bowl
  • Fork or potato masher
  • Knife
  • Cutting board
  • Spoon or spatula

Preparing the Eggs

Step 1: Boil

Place the eggs in a saucepan and cover with cold water.

Bring to a gentle boil.

Cook for 10–11 minutes for firm yolks.


Step 2: Cool

Transfer the eggs immediately into ice water.

Cool for about 5 minutes.

Peel carefully.


Making the Egg Filling

Chop or mash the eggs according to your preferred texture.

For a traditional Japanese-style filling:

  • Mash the yolks until smooth.
  • Finely chop the egg whites.
  • Combine both in a mixing bowl.

Add:

  • Japanese mayonnaise
  • Butter
  • Dijon mustard (optional)
  • Salt
  • Black pepper

Mix gently until creamy but still slightly chunky.

Avoid overmixing, which can make the filling pasty.


Preparing the Bread

Use fresh Japanese Shokupan.

Spread a thin layer of softened butter on one side of each slice.

The butter helps prevent the bread from becoming soggy.


Assembling the Sandwich

Spread a generous layer of egg filling evenly onto two slices of bread.

If using lettuce or cucumber, place them over the filling.

Cover with the remaining bread slices, buttered side facing inward.

Press gently to secure the filling without compressing the bread too much.


Cutting and Serving

Trim the crusts for the classic Japanese café presentation.

Cut each sandwich into:

  • Rectangles
  • Triangles
  • Finger sandwiches

Serve immediately, or chill briefly for a firmer filling before slicing.

  • Rich creamy filling
  • Mild egg flavor
  • Slight sweetness
  • Delicate tanginess
