Egg salad sandwich and fruits in the bento box

I am usually pretty good at organizing and following my constantly updated to-do list. But once in a while life does get overwhelmingly busy and I fail to plan ahead especially when juggling too many things at the same time. What ends up happening is I call my husband at the office asking him to meet me and the kids at a restaurant for dinner at the last minute.

One of the drawbacks of not cooking dinner at home is that I don’t have “leftover” to pack for my son’s bento (lunch box) the next day. I try to save some leftover in the freezer for an emergency like these, but sometimes no luck. On those days, the easy sandwich comes in handy.

Now for those living in the States, a peanut butter and jelly sandwich might be a common menu for children’s school lunch. However, both of my children always preferred hot panini sandwich than typical soft bread sandwich like these.

The turning point was when we were in Japan last April. My mother loves bakeries and we often visited many local bakeries to pick up fresh bread.

My children really enjoyed freshly baked bread from Japanese bakeries and they especially loved Egg Salad Sandwich, or we call it Tamago Sando (たまごサンド). Japanese sandwich usually uses crust-less white bread slices, probably from British influence. Compared to typical American egg salad sandwich, the Japanese version is very simple – there are no celery, chives or green onions. The eggs are seasoned simply with Japanese mayonnaise, salt and pepper, and sugar.

Now speaking of mayonnaise, I receive several questions from some of you about Japanese mayonnaise. What’s the difference from regular kind? Well, you can read more about it here.

My son loves this Egg Salad Sandwich and this menu is now one of my favorite backup bento plans. I hope you will give it a try and enjoy this simple egg salad sandwich!

Instructions
 

  • Gather all the ingredients. Make 1 boiled egg on the previous day to save time in the morning.
    Egg Salad Sandwich Bento Ingredients
  • In a small bowl, mash 1 soft or hard-boiled egg with a fork.
    Egg Salad Sandwich Bento 1
  • Add 1 Tbsp Japanese Kewpie mayonnaise and mix well. If it‘s not moist, you can add ½ Tbsp more.
    Egg Salad Sandwich Bento 2
  • Season with Diamond Crystal kosher salt and freshly ground black pepper (and 1 pinch sugar, if you‘d like). I like to add a bit more salt and pepper to give good flavor.
    Egg Salad Sandwich Bento 3
  • With 2 slices bread of your choice, spread the egg mixture on top of a slice of bread and put another slice of bread on top.
    Egg Salad Sandwich Bento 4
  • [Optional] Cut off the crusts of the bread. Japanese sandwiches usually don’t have crusts. Tip: Don‘t throw away the crusts! Use them to make Shokupan Crust Rusks. These crunchy, buttery snacks are so delicious! You can make them now or freeze those crust strips and make them later.
    Egg Salad Sandwich Bento 5
  • Cut the sandwich in half or thirds, depending on the bento box size.
    Egg Salad Sandwich Bento 6
  • Pack the sandwich in a bento box. Add some fruit and vegetables to fill the empty space. Enjoy!

I love Japanese egg salad more than almost anything else. I use 1/2 regular hard boiled eggs and 1/2 soy/marinated ramen eggs. It is so delicious!

Thank you for your recipe! I went to my local Japanese grocery store and bought the Japanese imported mayonnaise. I couldn’t find Japanese Pullman bread so I’ll use some soft white bread to try. Egg salad is my favorite.5 stars

Who knew something so simple would be so delicious? My husband got spoiled with eating tamago sando in Japan and now I try o remember to trim off the crust. I think the Kewpie mayo makes all the difference, too!5 stars

I love all the quick and simple recipes you provide! I always hated egg salad growing up but I decided to try yours since its so simple and I enjoyed it! So now I have a super simple sandwich option for when Im short on time. Thank you 😊5 stars

Hi Nami
What should I do to avoid the bread get soggy by the time we eat in the afternoon? I use English mayo (instead of Japanese mayo) and it is moist.

Really like your recipes – makes me want to cook more!

Thank you.

Love this recipe! Came out awesome! Thanks 🙂
Wish I could post a picture…

Will the bread get soggy if I make the sandwich the night before?

Thanks so much Nami!! I made it last night and wasn’t soggy at all when I had it for lunch the next day!

Hi Nami.. is it okay to make this a day in advance? do i need to store the sandwich in the fridge after i make it? cause i dont have time to make it in the morning..
Thanks..

Hi, do u mash the egg the prev. day and reheat it in the morning? How to reheat it?

Healthy, simple and quick! Just in time for my lunch to bring to my office on Monday! 🙂

Dear Nami San,

I really love your site especially to cook Japanese food for people like us who just love it. My family love the food and have made a point to have any kind of OIWAI in a nearby Japanese restaurant.

Like your TAMAGO SANDO, I also make potato sandwich in a similar manner and pack a mixture of egg sandwich with potato sandwich which enlightens my kids lunch box.

I would love to know how to make okhonomiyaki so that I can serve my kids with the same.

Thank you

Nami-san, I have only recently discovered your blog and I LOVE IT!!! Great recipes and photography!! I live in the UK, so sourcing some ingredients can be difficult, not to mention pricey. Thanks for coming up with alternatives for some of the condiments that are vital to achieve that authentically Japanese taste. I bought some konniyaku a week ago but have no idea what to use it for. Any suggestions? Marianna

That looks like a fantastic and simple sandwich! I originally thought that the filling was scrambled eggs, but when you mentioned boiled, that seems much easier in terms of advanced preparation. And the bento-ware is very cute. =) Thanks for sharing this quick lunch bento recipe!

Hi Nami, I love your recipes! Just wondering if you ever tried out your mom’s technique of making this with scrambled eggs? So curious if it is a faster substitute for hard boiled!

Hello, Amy. We’re happy to hear you enjoy Nami’s recipes!
Thank you for the reminder. Nami hasn’t had a chance to do this with scrambled eggs. She is planning to try it sometime. 😀

The sandwich looks so scrumptious. Just perfect for the lunch box 🙂

Thank you for this! I love egg salad sandwiches, but the recipe I’ve used in the past takes too much time to prepare for a quick lunch. Your recipe is perfect for when the craving for egg salad comes on, but I have less than an hour for lunch.
