Japanese Egg Sandwich – Tamago Sando (CREAMY)

This sandwich recipe uses only 5 simple, affordable ingredients that you might already have! You’ll crave this for breakfast, lunch, or a quick snack anytime.

Street Food Day 15: Tamago Sando
Welcome to Day 12 of Cooking 15 Street Foods for 15 Days! Today we are making one of our go-to Japan convenience stores snacks, Japanese Egg Sandwich – Tamago Sando! When we were in Tokyo with my parents, we fell in love with these convenience store egg salad sandwiches. They were so creamy, but perfectly seasoned! Of course, once we were back visiting Osaka, we had to get a few as well!
If you never tried Japanese Egg Sandwich, you are missing out. There is a reason why you can find it everywhere in Japan! The sweet, fluffy slices of milk bread are packed full with creamy egg-mayo filling. It’s so simple with only FIVE ingredients, but it is super-rich in flavor. If you’re tired of fried or hard boiled eggs, you have to get yourself some fluffy milk bread. I am about to blow your mind with this simple recipe!
Japanese Egg Sandwich Ingredients
- 10 Extra Large Eggs Free-Range
- ¼ cup Japanese Mayo
- 1 tsp Sugar
- Black Pepper
- Milk Bread for 4 Sandwiches

Creamy Egg Salad Filling
The first time I saw Japanese Egg Sandwich, I was confused about how they were able to get the egg salad filling so rich and creamy. After some research and many many Tamago Sandos later, I’ve figured out a few ingredients and tricks to use for creamy egg salad filling, every single time.

Cooking Eggs For Tamago Sando
I recommend using HIGH-quality eggs for the best Japanese Egg Sandwich. Free-Range Eggs are your best friend when it comes to the beautiful rich color you find in Tamago Sandos.
The next pro trick here is to separate and egg white and egg yolks. Don’t overcook the eggs, because you want them to be still creamy, and not dry. After you peel it, separate and egg white and egg yolks in two individual bowls. Mix Japanese Mayo with the egg yolk till super creamy, and then fold in chopped egg whites to add texture. It may seem like al ot of work, but TRUST ME, it is so worth it!

Japanese Mayo VS American Mayo
Let’s talk about the difference between Japanese Mayo and American Mayo. This question is one of the most commonly asked questions whenever I use Japanese Mayo. You can also substitute to American Mayo, but Kewpie Mayo is a STABLE item in my kitchen. To make an EXTRA creamy Japanese Egg Sandwich, I highly recommend finding some Japanese Mayo to get the most authentic flavor.
- Japanese Mayo is made with ONLY the yolk, which gives it richer flour and a more custard-like texture.
- Japanese Mayo is slightly sweeter as it is made with Rice Vinegar, giving it a sweeter tang versus American Mayo.
- No Salt and other seasoning are added except for MSG, which gives it its umami flavor!

Adding Flavor with MSG
Speaking of MSG and its horrible “Chinese Restaurant Syndrome” reputation from Western Culture the past few years, it isn’t that bad for you.
Many Recent studies have shown that MSG, a salt formed from glutamic acid, doesn’t cause the symptoms for which it’s so often blamed, such as headache, nausea, and even numbness. You’re more than likely safe to eat it, especially in small servings. [via Food & Wine] If you can eat salad dressing, chips, can soup with no problem, you are fine.

Milk Bread
Another key to a delicious Tamago Sando is that slightly-sweet Milk Bread. I am using Milk Bread that I got from my local Asian Supermarket today. It is a lot fluffier than normal sandwich bread. It also has a slight sweetness that pairs perfectly with Japanese Egg Salad. But, if you’re looking for something more homemade and decadent, you have to try my mom’s Milk Bread recipe. It’s the BEST milk bread I’ve ever had. If you can’t find milk bread, this recipe would really be best with any sweet, fluffy breads like brioche or Hawaiian Buns. But, it would still taste great with any sliced bread on hand.

How To Make Tamago Sando
- In a pot, add water and 1 tbsp of vinegar (this will help the eggshell be peeled easier later). Once the water is boiling, add in the eggs and cook for 10 minutes.
- Once eggs are cooked, let them rest in the ice bath for 5 minutes before peeling.
- Cut the eggs in half and separate the egg whites and the egg yolk into two separate bowls.
- Mix egg yolk with 1 tsp of sugar, black pepper to season, and Japanese mayo till everything is smooth and creamy.
- Chop the egg whites into small pieces and fold them in with the creamy egg yolk mixture
- Add the egg salad between two pieces of bread and put a weighted plate on top to rest for 5 minutes.
- Optional, cut off the crust, and enjoy!

You can make the egg mix the first day and store overnight in the fridge, and then assemble the sandwich the next day to keep it fresh!
I LOVE egg salad sandwiches so I’m definitely going to have to try this! How much MSG would you add to the egg mixture?

Hey there! I’ve been reading your website for a while now and finally got the bravery to
go ahead and give you a shout out from Houston Tx!
Just wanted to say keep up the fantastic job!
I made with two eggs. But one of the eggs fell apart while peeling so it became one white: two yolks. And I eyeballed the rest of the ingredients. OMG, best ever egg salad sandwich!!!!!!!! Thank you! So simple, yet so good. (I miss Japan’s 7-11). I’ll make it proper next time and with a whole carton of eggs!
This is so amazing, thank you. When we first came back from Japan, this was my lunches for work for the first 2 weeks!
Tamago Sando, just like 7-11 in Tokyo, this is our lunches during my surgery recovery! Oishii. Arigato Gozaimasu!
Hi Gregg, so happy they remind you of Japan! It’s actually why I had to make it myself!
