Step‑by‑Step Instructions for Japanese Egg Sandwich
Step 1: Boil the Eggs
Start by bringing a pot of water to a rolling boil over medium-high heat. Carefully add 6 Pete and Gerry’s organic eggs and boil for 7 minutes for medium soft-boiled or 10 minutes for hard-boiled. While they cook, prepare an ice bath in a large bowl with cold water and ice. Once done, transfer the eggs to the ice bath to halt cooking for about 5 minutes before peeling them when lukewarm.
Step 2: Make the Egg Salad
In a mixing bowl, gently mash the peeled eggs until creamy but still slightly chunky. Add in 1/4 teaspoon of sugar, 1/4 teaspoon of salt, 1/4 teaspoon of ground black pepper, and 4 tablespoons of Japanese mayonnaise. If desired, mix in 1-2 teaspoons of milk to achieve your preferred consistency. Stir until well combined, and taste for seasoning before setting aside your egg salad for the Japanese Egg Sandwich.
Step 3: Assemble the Sandwich
Take 4 slices of soft Japanese milk bread and spread 2 tablespoons of softened unsalted butter evenly on one side of each slice. With the buttered sides facing out, spread a generous layer of the egg salad mixture between two slices. Gently press down to ensure the egg salad holds together, then trim the crusts for that classic tamago sando look.
Step 4: Serve
Carefully slice the assembled Japanese Egg Sandwich in half, revealing the creamy filling inside. You can serve your delicious sandwich immediately, perfect for a satisfying lunch or snack. Feel free to garnish with chopped chives for a touch of freshness, and enjoy the delightful flavors of your homemade tamago sando!

Storage Tips for Japanese Egg Sandwich
- Fridge: Store the Japanese Egg Sandwich wrapped in plastic wrap or in an airtight container for up to 2 days. This helps maintain freshness and prevents the bread from drying out.
- Freezer: Although it’s best enjoyed fresh, you can freeze the egg salad separately for up to 1 month. Reassemble the sandwich right before serving.
- Reheating: If you’ve stored the sandwich, enjoy it cold or at room temperature. Avoid reheating as it may affect the texture of the bread.
- Assembling Tip: To prevent sogginess, prepare the egg salad ahead of time and assemble the sandwich just before serving, especially if using regular bread.
