Step‑by‑Step Instructions for Japanese Egg Sandwich
Step 1: Prepare Ice Bath
Begin by filling a large bowl with ice and water, creating a refreshing ice bath. This will be essential for stopping the cooking process of the eggs and ensuring a creamy texture. Set it aside while you move on to boiling the eggs, as it will be ready when the eggs are done cooking.
Step 2: Boil Eggs
In a medium pot, bring water to a rolling boil over high heat. Carefully lower in the 6 large Pete and Gerry’s Organic Eggs. For medium soft-boiled eggs, cook for about 7 minutes. If you prefer hard-boiled eggs, allow them to cook for around 10 minutes. Keep an eye on the clock for perfect timing!
Step 3: Chill Eggs
Once the cooking time is up, swiftly transfer the eggs into the prepared ice bath. Let them chill for approximately 2 minutes, allowing the cold water to halt the cooking process. After chilling, gently peel the eggs while they are still warm to make the peeling easier and maintain a silky texture for your Japanese Egg Sandwich filling.
Step 4: Make Egg Salad
In a mixing bowl, mash the peeled eggs with a fork until broken into small pieces. Stir 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, add 1 to 2 teaspoons of milk for extra creaminess. Mix well until all ingredients are fully combined, adjusting seasoning to taste.
Step 5: Assemble Sandwich
Take 4 slices of fluffy Japanese milk bread and spread 2 tablespoons of softened unsalted butter evenly on one side of each slice. Spoon a generous portion of the creamy egg salad onto one slice, then top with another slice, pressing down gently. Remove the crusts if you prefer a classic look, ensuring that the delicious filling stays contained.
Step 6: Serve
Slice the assembled Japanese Egg Sandwich in half, making for easier handling and serving. If desired, garnish with sliced chives for a fresh touch that enhances both flavor and appearance. These delightful sandwiches are best enjoyed fresh but can be stored for later, making them perfect for packed lunches or quick snacks at home.

Japanese Egg Sandwich Recipe FAQs
What type of eggs should I use for the egg salad?
Absolutely! For the best flavor and texture in your Japanese Egg Sandwich, I recommend using high-quality organic eggs. They provide a richer and creamier egg salad that truly elevates the sandwich experience. Look for eggs with a vibrant yolk color, indicating freshness.
How should I store my Japanese Egg Sandwich?
For optimal freshness, store your assembled sandwiches in an airtight container in the fridge for up to 2 days. Be sure to wrap them well in plastic wrap or keep them contained to avoid sogginess. This way, they retain their delightful taste and texture, ready to enjoy at a moment’s notice!
Can I freeze my Japanese Egg Sandwich?
Very! If you’d like to save some for later, you can freeze your sandwiches. Allow them to cool completely before wrapping each one tightly in plastic wrap or aluminum foil. They can last in the freezer for up to 2 months. Just remember, the texture may change slightly upon thawing, so it’s best to consume them after properly thawing in the fridge overnight.
What should I do if my eggs are hard to peel?
If you find your hard-boiled eggs are sticking to the shell, it could be due to using fresher eggs. To avoid this, I suggest using slightly older eggs, as they tend to peel more easily. Also, remember to place them in an ice bath immediately after boiling to stop the cooking process, which helps with peeling as well.
Are there any dietary considerations I should keep in mind?
Absolutely! If you’re serving the Japanese Egg Sandwich to children or someone with dietary restrictions, keep in mind that this recipe contains eggs and mayonnaise, which are common allergens. Additionally, you may consider using plant-based milk and egg-free mayo to accommodate those with dairy or egg allergies. Always check labels for specific ingredients if serving to someone with allergies.
How can I achieve the best creamy texture in my egg salad?
For a smooth and creamy egg salad, ensure you mash the peeled eggs thoroughly. Start by breaking the eggs into smaller pieces in a bowl, then mix in your toppings like mayonnaise, sugar, and other seasonings. If you want an extra boost of creaminess, consider adding 1 to 2 teaspoons of milk or plant milk. Adjust the seasoning to taste to get that balance just right!
