Step‑by‑Step Instructions for Japanese Egg Sandwich
Step 1: Prepare Ice Bath
Fill a large bowl with ice and water, ensuring it’s deep enough to submerge your eggs later. This ice bath is crucial for stopping the cooking process, making it easier to peel them after boiling. Set it aside while you move on to boiling the eggs for your delectable Japanese Egg Sandwich.
Step 2: Boil Eggs
In a medium pot, bring water to a rolling boil over high heat. Carefully lower in large organic eggs, ensuring they are fully submerged. For soft-boiled eggs, cook for 7 minutes; if you prefer hard-boiled, let them boil for 10 minutes. Keep an eye on the time, as these are essential for achieving that perfect, creamy texture in your egg salad.
Step 3: Chill Eggs
As soon as your timer goes off, promptly transfer the boiled eggs into the ice bath using a slotted spoon. Let them chill for about 2 minutes, which will not only stop the cooking but will also help in easy peeling later on. This step ensures that your eggs are perfectly cooked while maintaining that delightful creamy yolk for the Japanese Egg Sandwich.
Step 4: Peel Eggs
Once the eggs are cool to the touch, gently remove them from the ice bath. Start peeling while they’re still slightly warm for easier removal of the shells. As you peel them, take care to avoid any cracks in the white, as this will help maintain the integrity of the egg salad you’ll be making for the Japanese Egg Sandwich.
Step 5: Make Egg Salad
In a mixing bowl, mash the peeled eggs with a fork until they resemble a chunky yet creamy texture. Stir in sugar, salt, ground black pepper, and Japanese mayonnaise. If using hard-boiled eggs, add a splash of milk or plant milk to achieve a moist consistency. Adjust the seasoning according to your taste to create the perfect filling for your Japanese Egg Sandwich.
Step 6: Assemble Sandwich
Take slices of Japanese milk bread and spread a thin layer of unsalted butter on one side of each slice. Generously layer the creamy egg salad onto one slice, pressing gently to secure the filling. Top with another slice of bread, butter side down, and then use a sharp knife to trim off the crusts for a tidy presentation that will make your Japanese Egg Sandwich irresistible.
Step 7: Serve
Cut the finished sandwiches diagonally or in halves, depending on your preference. Serve them immediately to enjoy the softness of the bread and the creaminess of the egg salad, or wrap them up for a delightful lunch later. These Japanese Egg Sandwiches are perfect for sharing and are sure to be a hit with family and friends!

Storage Tips for Japanese Egg Sandwich
- Fridge: Store assembled sandwiches in an airtight container for up to 2 days to preserve the fluffy texture of Japanese milk bread and the creaminess of the egg salad.
- Freezer: While it’s not recommended to freeze assembled sandwiches due to the change in texture, you can freeze the egg salad separately for up to 1 month. Thaw in the fridge overnight before using.
- Wrapping: Wrap each sandwich in plastic wrap or parchment paper before refrigerating to prevent them from drying out and to keep them fresh.
- Reheating: If you’ve stored the egg salad separately, gently reheat in a microwave for about 15-20 seconds to bring it to a comfortable temperature before assembling your Japanese Egg Sandwich.

Japanese Egg Sandwich (Tamago Sando) Recipe FAQs
How do I select the best eggs for my Tamago Sando?
Absolutely! For the best flavor and texture in your Japanese Egg Sandwich, I recommend using large organic eggs. They produce a richer and creamier egg salad. If organic eggs aren’t available, regular eggs will work just fine, but you might notice a slight difference in taste.
What’s the best way to store my assembled Japanese Egg Sandwich?
Store your assembled sandwiches in an airtight container in the fridge for up to 2 days. This ensures that the fluffy texture of the Japanese milk bread remains intact and the creamy filling stays fresh. If you notice any moisture buildup, I suggest wrapping each sandwich in plastic wrap to avoid drying out.
Can I freeze the Japanese Egg Sandwich?
While it’s not ideal to freeze assembled sandwiches due to the change in texture, you can freeze the egg salad itself! To do this, simply prepare the egg salad according to recipe instructions, place it in a freezer-safe container, and store it for up to 1 month. When you’re ready to use it, thaw the egg salad in the fridge overnight and then assemble your sandwich fresh.
What should I do if my egg salad turns out too dry?
Very! If your egg salad lacks moisture, it might be due to overcooked eggs or not enough mayonnaise. For a creamy fix, simply stir in a splash of milk or plant milk, ensuring a luscious texture. Feel free to add a bit more Japanese mayonnaise for that authentic flavor too! Adjust seasonings to taste as you mix.
Are there any dietary considerations for my Japanese Egg Sandwich?
Absolutely! If you have allergies or dietary restrictions, be sure to use alternatives that fit your needs. For example, if someone has an egg allergy, try a chickpea salad as a filling. Additionally, check the mayonnaise—Japanese mayonnaise typically contains eggs, so using an egg-free version is essential if you need to avoid that allergen.
How can I tell if my eggs are fresh enough?
To check the freshness of your eggs, you can use the water test! Fill a bowl with water and gently place the eggs into it. Fresh eggs will sink and lay flat on the bottom. If they stand upright or float, it’s best to discard them. This simple test saves you from any mishaps in your delicious Tamago Sando!
