How to Make Japanese Egg Sandwich (Tamago Sando)
Step 1: Boil and Cool the Eggs
Gently place your eggs in a medium saucepan and cover with cold water, making sure the eggs are submerged by about an inch. Set the pan over medium heat, bring to a boil, then cook for 12 minutes. When the timer dings, transfer the eggs straight into ice-cold water to halt cooking—this prevents gray rings and makes them easy to peel. Let them cool completely.
Step 2: Prepare the Egg Salad Filling
Peel your chilled eggs and transfer them to a bowl. Using a fork, mash the eggs—try to keep the pieces of white bite-sized and fairly even, leaving just a bit of texture. Now, stir in the sugar, salt, pepper, and milk. The milk helps the mixture become more light and creamy. Finally, add Japanese Kewpie mayonnaise and mix until everything is irresistibly smooth and velvety. Taste and season as needed.
Step 3: Butter and Layer the Shokupan
Lay out the slices of shokupan. Slather each slice with a little salted butter—this isn’t just for flavor; it creates a delicious barrier that keeps your bread fluffy and the filling from soaking through. For each sandwich, add a generous scoop of egg salad to one slice, then top with another, buttered side down.
Step 4: Compress and Cut
To get that true Tamago Sando look and texture, gently press the assembled sandwiches between two plates for a few minutes. This sets the filling and makes for those satisfyingly neat edges. Afterward, trim the crusts for an authentic Japanese touch (and save them for homemade rusks if you like!). Slice the sandwiches in half and serve immediately.
Pro Tips for Making Japanese Egg Sandwich (Tamago Sando)
- Egg Texture Matters: For extra tenderness, don’t over-mash your eggs—keep some small bites of white for that signature Japanese Sando texture.
- Choose the Right Mayo: Only Kewpie gives you that true umami flavor and creamy consistency—American mayo will make a drier, milder filling.
- Chill Before Cutting: Cooling your sandwiches (even just 5–10 minutes after pressing) firms up the filling and helps get those restaurant-worthy, sharp edges.
- Don’t Discard the Crusts: Save shokupan crusts in a freezer bag and toast them into homemade rusks—there’s nothing better with coffee tomorrow!
How to Serve Japanese Egg Sandwich (Tamago Sando)
Garnishes
The beauty of this sandwich is its simplicity, so you don’t need much, but a delicate sprinkle of extra cracked black pepper or finely chopped chives right before serving takes it to the next level. If you want a hint of color, a tiny dusting of togarashi (Japanese chili powder) can add a subtle, playful heat.
Side Dishes
Pair your Japanese Egg Sandwich (Tamago Sando) with a crisp seasonal salad, miso soup, or even a handful of Japanese pickles for a bento-inspired lunch. Fruit slices—like orange or apple—are wonderfully refreshing too.
Creative Ways to Present
For that café-worthy look, slice your sandwiches in half and stack them so the creamy filling is on full display. Wrap each half in parchment and tie with twine for a picnic. Or, cut into triangles or thin fingers and serve as afternoon tea-style mini sandwiches—a guaranteed crowd-pleaser!
Make Ahead and Storage
Storing Leftovers
Wrap any leftover Japanese Egg Sandwich (Tamago Sando) tightly in plastic wrap or store in an airtight container. Keep it in the refrigerator and enjoy within 24 hours for the freshest flavor and texture.
Freezing
Freezing isn’t recommended for this sandwich—the creamy egg filling and delicate shokupan change texture after thawing. But you can freeze the crusts to make rusks or bread crumbs later on!
Reheating
This sandwich is truly best enjoyed chilled or at room temperature. If you need to “refresh” it, let it sit out for a few minutes after refrigeration—there’s no need to microwave, as warming will affect both texture and that signature creamy filling.
FAQs
-
What is the difference between Kewpie and regular mayonnaise, and can I substitute?
Kewpie mayonnaise is made with only egg yolks (not whole eggs) and rice vinegar, resulting in a richer texture and tangier, slightly sweet flavor. You can substitute with regular mayo in a pinch, but the flavor will be milder and the filling just a touch less luxurious.
-
Can I make the egg salad filling ahead of time?
Yes! You can make the filling a few hours in advance—just keep it covered and chilled in the refrigerator. Assemble the sandwiches just before serving for the best texture.
-
Is there a vegetarian or vegan way to make Japanese Egg Sandwich (Tamago Sando)?
Absolutely! For a vegan twist, swap out eggs for tofu “egg salad” (using crumbled firm tofu and a bit of turmeric for color), and use vegan mayonnaise and plant-based butter. The method stays just as simple.
-
Why do you press the sandwiches before slicing?
Pressing the sandwiches sets the filling, giving you those signature tidy edges and ensuring each bite is neat and satisfying—just like you’d find at a Japanese bakery or café.
