A perfectly crafted Japanese egg sandwich (Tamago Sando) is the ultimate balance of comfort and refinement. This iconic sandwich features a cloud-like egg filling nestled between slices of pillowy milk bread. The filling achieves an almost custard-like texture through precise cooking and mixing techniques, creating something far more elegant than a typical egg salad sandwich. Each element works in harmony for a creation that's simultaneously rich yet delicate.

Serving Suggestions

Complete the meal with traditional accompaniments like hot miso soup or chilled cucumber slices. For breakfast, serve alongside natto. During warmer months, pair with cold green tea and pickled vegetables for a refreshing combination.

Storage Guidelines

Keep filling and bread separate until serving. Store egg mixture in an airtight container with plastic wrap directly on surface. For packed lunches, wrap assembled sandwiches in plastic, then foil, and finally paper towel. Transport with ice pack in insulated container.

Frequently Asked Questions

→ What sets a Japanese egg sandwich apart from a regular egg salad sandwich?
The difference lies in the Japanese mayo, which has a richer taste, along with carefully timed egg boiling and the removal of bread crusts for a soft, uniform bite.
→ Can I replace Japanese mayo with regular mayo?
You could substitute it, but the distinctive creaminess and taste of Japanese mayo, like Kewpie, give tamago sando its authentic flavor.
→ What’s a good alternative to Japanese milk bread?
If milk bread isn’t on hand, try soft, dense options like pain de mie or brioche, which work wonderfully as substitutes.
→ Why is the crust usually removed?
Crust removal is a typical practice in Japanese sandwiches for a neater look and smoother texture throughout.
→ Can I prepare the filling in advance?
Sure, the egg mixture can be made a day ahead. Keep it refrigerated and assemble your sandwich when ready to enjoy.

Difficulty: Intermediate

Cuisine: Japanese

Yield: 2 Servings (2 sandwiches)

Dietary: Vegetarian

Ingredients

→ Egg Salad

01 6 big eggs
02 A pinch of sugar (around 1/4 teaspoon)
03 A small shake of salt (1/4 teaspoon)
04 1/4 teaspoon black pepper, ground
05 1-2 teaspoons of milk or non-dairy milk (optional)
06 4 tablespoons of creamy Japanese-style mayo

→ Assembly

07 4 soft slices of Japanese milk bread
08 2 tablespoons softened, unsalted butter
09 Optional: chopped chives for decorating

Instructions

Step 01

Fill a big bowl with ice and cold water. This stops the eggs from cooking any further once you take them out.

Step 02

Heat enough water in your pot so the eggs will be completely under. Bring it to a boil, carefully add the eggs, and cook for 7 minutes if you want them soft in the middle, or 10 minutes for firm yolks. Let them sit in the warm water for another minute, then move them to the ice bath for 2 minutes. Peel them while they're still warm to the touch.

Step 03

Mash those peeled eggs in a bowl with a fork. Sprinkle in the sugar, pepper, and salt, mashing as you mix until the pieces are small but still noticeable. Add the Japanese mayo and, if you're using hard-boiled eggs, a splash of milk to make it smoother.

Step 04

Spread the soft butter evenly on the bread slices. Scoop the egg mixture evenly onto one slice, then place the second slice on top with the buttered side facing in. Gently press the sandwich together, and slice off the crusts like you’d see in Japanese-style sandwiches.

Step 05

Slice the sandwich in half, sprinkle some chives on top for flair if you like, and enjoy while it’s fresh.

Notes

  1. Works great as a packed lunch or for a picnic
  2. Wrap it in plastic wrap, and it'll stay fresh in the fridge for 2 days
  3. Only add milk if your eggs are fully boiled to keep the filling creamy
