Step‑by‑Step Instructions for Japanese Egg Sandwich
Step 1: Prepare Ice Bath
Start by filling a large bowl with ice water to create an ice bath. This essential step will immediately halt the cooking process and ensure your eggs maintain a perfectly tender texture. Set the ice bath aside while you prepare to boil the eggs; it will be crucial for achieving that ideal creamy consistency in the Japanese egg sandwich.
Step 2: Boil Eggs
In a medium pot, bring water to a rolling boil over high heat. Once boiling, gently lower in your high-quality organic eggs, using a slotted spoon. For a medium soft-boiled egg, cook for 7 minutes, or for hard-boiled eggs, opt for 10 minutes. Keep an eye on the clock, as timing is key to achieving your desired egg texture!
Step 3: Chill Eggs
Once the cooking time is up, carefully transfer the eggs to the prepared ice bath using the slotted spoon. Allow them to sit in the ice water for about 2 minutes. This quick cooling not only stops further cooking but also makes peeling the eggs much easier, setting you up for the delightful egg salad in your Japanese egg sandwich.
Step 4: Peel and Mash Eggs
After the eggs have cooled, gently tap each one on a hard surface to crack the shell, then peel it away under running water for easier removal. In a mixing bowl, carefully mash the peeled eggs with a fork until they reach a creamy consistency. There should still be some texture to provide that satisfying bite within your Japanese egg sandwich.
Step 5: Mix Egg Salad
To the bowl of mashed eggs, add a dash of sugar, a sprinkle of salt, ground black pepper, and your desired amount of Japanese mayonnaise. If you’re using hard-boiled eggs, consider adding a splash of milk to maintain moisture. Stir everything with a spatula until completely combined, ensuring that every bite of your egg salad is perfectly flavored for the Japanese egg sandwich.
Step 6: Assemble Sandwich
Gather your soft, fluffy Japanese milk bread and spread a layer of softened unsalted butter on both slices. Place a generous scoop of the creamy egg salad onto one slice, spreading it out evenly. Top with the second slice of bread, then trim off the crusts for a classic presentation. Your Japanese egg sandwich is now ready to be enjoyed!
Step 7: Serve Immediately
Slice your assembled sandwich in half and serve it fresh for the best taste and texture. You can also wrap it in plastic wrap for later. Pair it with some pickles or fresh fruit to create a balanced meal. Enjoy the rich flavors and comforting experience of your homemade Japanese egg sandwich!

Japanese Egg Sandwich (Tamago Sando) Recipe FAQs
What type of eggs should I use for the best flavor?
Absolutely! I recommend using high-quality organic eggs for your Japanese egg sandwich. They provide the richest flavor and the most delightful creaminess in your egg salad.
How should I store the assembled sandwich?
To keep your Japanese egg sandwich fresh, wrap it in plastic wrap and store it in the refrigerator for up to 2 days. If you’d like to maintain the best quality, prepare the egg salad separately and assemble the sandwich on the day of consumption.
Can I freeze the egg salad for later use?
Absolutely! You can freeze the egg salad in an airtight container for up to 1 month. When you’re ready to enjoy it, just thaw it overnight in the refrigerator and assemble your sandwich fresh. This way, you’ll have a delicious, homemade meal ready at your convenience!
What should I do if my eggs are overcooked and rubbery?
If you notice your eggs turning rubbery, it might be due to overcooking. To avoid this, always set a timer and use the ice bath method immediately after boiling, which cools the eggs quickly and helps maintain their tender texture. If you find them that way after boiling, don’t panic! You can still mash the eggs gently and mix them well with the mayonnaise to create a creamier egg salad, masking the texture a bit.
Is this recipe suitable for people with egg allergies?
Unfortunately, this recipe is not suitable for those with egg allergies. However, you could experiment with alternatives like mashed avocado or chickpeas combined with vegan mayo for a similar creamy effect. While it won’t replicate the exact flavor, it could still make for a delicious sandwich!
Can I use regular mayonnaise instead of Japanese mayonnaise?
While you can use regular mayonnaise, I must mention it may compromise the authentic flavor of the Japanese egg sandwich. Japanese mayonnaise is richer and creamier, enhancing the overall taste. If you prefer the regular version, consider adding a touch of sugar to mimic the sweetness found in Japanese mayonnaise.
