Preparing the Japanese Egg Sandwich
Creating a delightful Japanese egg sandwich, or tamago sando, is a simple yet satisfying process. Let's walk through the steps together to transform everyday ingredients into a delicious lunch staple!
Gather Your Ingredients
Before you start, it’s essential to have everything ready to go. Here’s what you’ll need for your Japanese egg sandwich:
- 3 large eggs (approximately 50 g each, without the shell)
- ¼ teaspoon sugar
- ¼ teaspoon Diamond Crystal kosher salt
- ⅛ teaspoon freshly ground black pepper
- 2 teaspoon milk
- 2 tablespoon Japanese Kewpie mayonnaise
- 4 slices of shokupan (Japanese milk bread)
- Salted butter
Having these ingredients at your fingertips makes the cooking process smoother and more enjoyable.
Boil and Cool the Eggs
Start by putting the eggs in a medium saucepan and filling it with enough water to cover them by about an inch (2.5 cm). Bring the water to a boil over medium heat. Once bubbling, let the eggs cook for around 12 minutes. After that, transfer the eggs to a bowl filled with iced water. This stops the cooking process and makes peeling easier. Once cool, peel the eggshells off—this should be a cinch!
Mash the Eggs and Mix in Seasoning
Next, place the peeled eggs in a bowl and use a fork to mash them. The goal here is to break the egg whites into small, uniform pieces. Now, sprinkle in ¼ teaspoon of sugar and ¼ teaspoon of Diamond Crystal kosher salt, along with ⅛ teaspoon of freshly ground black pepper. Pour in 2 teaspoon of milk and 2 tablespoon of Japanese Kewpie mayonnaise. Mix everything together thoroughly. Taste your egg salad, and feel free to adjust the seasoning to suit your preferences.
Assemble the Sandwich
Now comes the fun part! Lay out your 4 slices of shokupan. Generously spread salted butter over the top of each slice. Next, scoop some of that lovely egg salad onto one slice and gently place another slice on top, buttered side down. For added compression and flavor melding, place the assembled sandwiches between two plates for about 5 minutes.
Slice and Store Appropriately
Finally, use a sharp knife to cut off the crusts of the sandwiches—don't waste them! You can transform those crusts into Shokupan Crust Rusks for a delicious snack (or freeze them for later!). Slice the sandwiches in half and voila, your Japanese egg sandwich is ready to enjoy!
If you find yourself with leftovers, simply store them in an airtight container in the refrigerator for up to two days. Enjoy your delightful homemade tamago sando with a side of pickles or a simple salad for a complete meal. Happy eating!

Variations on the Japanese Egg Sandwich
Tamago Sando with Avocados
For a creamy twist, why not add avocado to your Japanese egg sandwich? Simply mash a ripe avocado and spread it on the bread before adding your egg salad. The buttery texture complements the richness of the eggs beautifully, making every bite indulgent. Plus, avocados are loaded with healthy fats and nutrients, elevating the sandwich to a new level of flavor and healthiness.
Spicy Tamago Sando with Sriracha
If you love a kick, try a spicy Tamago Sando by drizzling sriracha into your egg salad. Just a teaspoon can transform your traditional Japanese egg sandwich into a zesty delight! Mix in sautéed scallions or a sprinkle of sesame seeds for an extra crunch and depth of flavor. Don’t forget to pair it with a cool drink, like iced tea or sparkling water, to balance the spice.
Feel free to experiment with these variations and make this beloved sandwich your own!
Cooking Tips and Notes for the Japanese Egg Sandwich
Getting the eggs just right
To achieve the perfect creamy filling for your Japanese egg sandwich, start by boiling your eggs for exactly 12 minutes. This ensures that the yolks are fully cooked but not chalky. Surprising how something so simple can make all the difference! Don't forget to transfer them to ice water immediately after boiling to stop the cooking process. This technique prevents grey rings around the yolk and keeps everything beautifully yellow.
Choosing the bread for your sandwich
When it comes to bread, shokupan, or Japanese milk bread, is the only way to go. It’s soft, fluffy, and just thick enough to hold your egg salad without getting soggy. If you can’t find it in stores, consider making your own shokupan. Trust me, your sandwich will get an upgrade that you didn’t even know you needed! Spread a generous layer of salted butter to enhance the flavors further, and you're all set for an amazing lunch.

Serving Suggestions for the Japanese Egg Sandwich
Serve with a Side of Pickled Vegetables
To elevate your Japanese egg sandwich, pair it with a delightful assortment of pickled vegetables. The tangy crunch of pickles, such as tsukemono (Japanese pickles), creates a refreshing contrast that balances the creamy egg salad. Try incorporating pickled radishes or cucumber for an added zing. Not only do they enhance your meal, but they also bring a touch of color to your plate.
Perfect Pairings for Tea or Coffee
Looking for the ideal beverage to accompany your Japanese egg sandwich? A warm cup of Hojicha (roasted green tea) complements the savory richness perfectly. If you prefer coffee, opt for a smooth blend like a medium roast that won’t overwhelm the sandwich's flavors. This delightful pairing makes for a perfect breakfast or afternoon snack!
