Let me tell you about the sandwich that made me fall headfirst into the world of Japanese convenience store food: the Japanese Egg Sandwich, or Tamago Sando. You’d think a simple egg salad between slices of bread couldn’t possibly be life-changing, right? But then Japan had to go and perfect it.
This isn’t your typical American picnic-style egg salad. We’re talking ultra-soft Japanese milk bread that practically melts in your mouth, hugging a creamy, tangy, slightly sweet egg filling that tastes like it was whipped up by angels. These sandwiches are everywhere in Japan—from 7-Eleven to upscale bakeries—and they’ve won the hearts of home cooks and street food lovers alike.
So, if you’re a busy parent trying to pack school lunches, a student hunting for an easy high-protein lunch, or just someone looking to jazz up their sandwich game, Tamago Sando is about to become your go-to.
Today, I’m showing you how to make this creamy, dreamy, no-fuss Japanese egg sandwich in your own kitchen.

Ingredients & Kitchen Notes
The Japanese Egg Sandwich is more than just a quick meal—it’s a comfort food experience wrapped in milk bread
Eggs:
This is the star of the show, so use the best you can find. I recommend Pete and Gerry’s Organic Eggs for their bright yolks and rich flavor. You can go soft-boiled for a gooier texture, or hard-boiled for a firmer bite. Both are delicious—just depends on what you like.
Japanese Mayonnaise:
Here’s where things take a turn from your usual Hellmann’s. Japanese mayo (like Kewpie) uses only the yolks and is made with apple or rice vinegar instead of distilled vinegar. It’s creamier, richer, and has that signature umami flavor that sets Tamago Sando apart.
Japanese Milk Bread (Shokupan):
This bread is soft, fluffy, slightly sweet, and absolutely essential. It makes the sandwich feel pillowy and indulgent. If you can’t find it, a good-quality fluffy white sandwich bread will do.
Other Ingredients:
You’ll also need a little salt, pepper, a pinch of sugar, and optionally, a splash of milk to help soften the texture if you’re using hard-boiled eggs.

How to Make Tamago Sando (Step-by-Step)
One of the secrets to a standout Japanese Egg Sandwich is getting that soft, rich texture by balancing mayo and perfectly boiled eggs
Step 1: Boil the Eggs
First, decide on your yolk vibe.
- Soft-boiled: Bring water to a gentle boil, then carefully lower your eggs in. Boil for 7 minutes, then plunge into an ice bath.
- Hard-boiled: Go for 10–11 minutes, then ice bath.
The ice bath isn’t just a fancy touch—it makes the eggs easier to peel and stops the cooking, giving you perfect doneness every time.
Step 2: Make the Egg Salad
Peel your eggs and get to mashing. You can use a fork, potato masher, or even just a whisk.
To the mashed eggs, add:
- 3 tablespoons of Kewpie mayo
- 1 teaspoon of sugar
- Salt and pepper to taste
- 2 tablespoons of milk (optional, great if your eggs are more on the dry side)
Mix until creamy. Some people like it chunky, others prefer it whipped smooth. Me? I leave a few yolk clumps for texture.
Want to go extra? Add chopped chives, a dash of mustard, or even a sprinkle of wasabi powder for a kick.
Step 3: Assemble the Sandwich
Take your slices of milk bread and lightly butter the inside of each slice. This keeps the bread from getting soggy and adds a little extra richness.
Spread a generous scoop of the egg salad onto one slice. Gently press the other slice on top. Trim the crusts—yes, it’s part of the authentic experience—and slice into halves or thirds.
Pro tip: Wrap the sandwich tightly in plastic wrap and chill for 10 minutes before serving. It helps the filling set and makes it easier to cut.

Storage & Make-Ahead Tips
Tamago Sando is perfect for meal prep. Here’s how to store it like a pro:
- Fridge storage: Wrap it in wax paper or plastic and refrigerate. It’ll keep well for up to 2 days, especially if you’re using milk bread which holds moisture beautifully.
- Lunchbox-ready: Toss it into a bento box with some fruit, pickles, or a small salad, and you’ve got a high-protein, travel-friendly meal.
If your bread’s a little past its prime, lightly toasting it can bring it back to life. Just don’t over-toast—you want softness, not crunch.
FAQ
