Step‑by‑Step Instructions for Japanese Egg Sandwich (Tamago Sando)
Step 1: Prepare Ice Bath
Start by filling a large bowl with ice water. This ice bath is essential to halt the cooking process of the eggs once boiled, ensuring they reach perfect doneness. Set the bowl aside near your cooking area for easy access when the eggs are ready.
Step 2: Boil Eggs
Bring a pot of water to a rolling boil over medium-high heat. Carefully add Pete and Gerry’s organic eggs to the boiling water using a slotted spoon. For medium soft-boiled eggs, cook for 7 minutes; for hard-boiled, let them simmer for 10 minutes. Keep an eye on the time, as overcooking can lead to a rubbery texture.
Step 3: Chill Eggs
Once the eggs are done cooking, quickly transfer them to the prepared ice bath using the slotted spoon. Let them sit in the ice water for about 2 minutes to cool and stop the cooking process. This technique also makes peeling easier, so don’t skip this crucial step!
Step 4: Make Egg Salad
After the eggs have cooled, peel them while they are still warm for smoother results. In a mixing bowl, mash the peeled eggs with a fork until they reach your desired consistency. Add sugar, salt, ground black pepper, and Japanese mayonnaise (and milk if using). Mix well until creamy, tasting to adjust seasoning as needed.
Step 5: Assemble Sandwich
Spread a thin layer of unsalted butter on the slices of Japanese milk bread for added richness. Place a generous layer of the creamy egg salad on one slice, then gently top with another slice of bread. For a classic presentation, carefully cut off the crusts to create a neat sandwich, and feel free to garnish with chives if desired.
Step 6: Serve Immediately
Your delightful Japanese egg sandwich (tamago sando) is now ready to enjoy! Serve it immediately for the best flavor and texture. Alternatively, if preparing in advance, wrap the sandwiches tightly in plastic wrap and store them in the fridge, where they will stay fresh for up to 2 days.

Helpful Tricks for Tamago Sando
-
Egg Consistency Check: Use a timer when boiling eggs! For soft, creamy results, stick to 7 minutes for medium soft-boiled eggs; overcooking leads to rubbery texture.
-
Chill for Easy Peeling: Remember to transfer boiled eggs to the ice bath immediately. This technique not only stops cooking but also makes peeling much easier.
-
Season to Taste: Don’t skip tasting your egg salad before serving! Adjust seasoning after adding Japanese mayonnaise, as it can enhance saltiness.
-
Bread Matters: Choose high-quality Japanese milk bread for the best sandwich experience. It’s light and fluffy—perfect for cradling that creamy egg salad!
-
Wrap it Right: If making in advance, store your Japanese Egg Sandwich tightly wrapped in plastic. This keeps it fresh and prevents it from getting soggy.

Japanese Egg Sandwich (Tamago Sando) Recipe FAQs
What kind of eggs should I use for Tamago Sando?
Absolutely, I recommend using Pete and Gerry’s Organic Eggs for the best flavor and texture. They offer a rich creaminess that creates a truly delectable egg salad. You can choose between medium soft-boiled eggs for extra richness or hard-boiled ones for a firmer bite.
How long can I store my Japanese Egg Sandwich?
Your delicious tamago sando can be stored in the fridge for up to 2 days. Make sure to wrap it tightly in plastic wrap or use an airtight container to preserve its freshness and prevent it from getting soggy.
Can I freeze the egg salad for my sandwiches?
Yes! You can freeze the egg salad filling separately from the bread for up to 1 month. Just place the cooled egg salad in an airtight container. When you’re ready to enjoy it, simply thaw the filling in the fridge overnight and then assemble your sandwich as usual. Avoid freezing the assembled sandwich, as the bread may become soggy after thawing.
What should I do if my eggs turn out rubbery?
Very! If you’ve overcooked your eggs and they turned rubbery, there’s still a way to save them. When making the egg salad, mash the eggs while they’re warm, then mix in a bit of extra Japanese mayonnaise or milk to improve the creaminess. You can also try adding a pinch of sugar to help balance the texture and flavor.
Are there any dietary considerations for making this sandwich?
Absolutely! For those with egg allergies, this recipe is not suitable unless you find an egg substitute that works for you. If you’re concerned about dietary restrictions, consider checking the ingredients for the mayonnaise you choose. Japanese mayonnaise typically contains more egg yolks and has a different flavor profile than regular mayo, so choose what best fits your needs.
How can I make my egg salad even creamier?
Of course! If you want to amp up the creaminess of your egg salad, try adding a splash of milk or plant-based milk when mixing in the mayonnaise. Start with a tablespoon, mix, and taste. You can always add a little more if you prefer a creamier texture. Another fantastic tip is to slightly under-boil your eggs for a creamier consistency in the salad, but don’t forget to chill them in an ice water bath immediately after cooking!
