Egg Salad Sandwich たまごサンド弁当

Egg Salad Sandwich Bento |

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 last minute.

One of the drawback 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 freezer for emergency like these, but sometimes no luck.  On those days, easy sandwich comes in handy.

Now for those living in the States, 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.

Egg Salad Sandwich Bento |

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

My children really enjoyed fresh 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, Japanese version is very simple – there is 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 plan.  I hope you will give it a try and enjoy this simple egg salad sandwich!

Egg Salad Sandwich Bento
Prep time
Total time
Serves: 1 sandwich
  1. Make a hard boiled egg on the previous day to save time in the morning.
  2. In a small bowl, mash the boiled egg with a fork.
  3. Add 1 Tbsp. of mayonnaise and mix well. If it's not moist, you can add ½ Tbsp. more.
  4. Season with salt and pepper (and sugar if you like). I like to add salt and pepper a bit more than what I usually add to give good flavor.
  5. Spread the egg mixture on top a piece of bread and put another slice of bread on top.
  6. (Optional) Cut off the edges of the bread. Japanese sandwiches usually don’t have edges.
  7. Cut the sandwich into 2-3 parts depending on the bento box size.
  8. Pack the sandwich in bento box and put some fruits and vegetables in the empty space.
A little bit of sugar is a typical ingredient for Japanese egg salad, but I usually don't add it.

This lunch is for my 6-year-old son.

  1. What a coincidence! I just boiled some eggs for my lunch and now I’m craving this egg salad sandwich after reading your post. Our own version is similar to yours, too – quite simple with just mayo, salt and pepper. But I love the bread you used and removing the crusts is just perfect. Thanks for sharing this great, easy sandwich idea, Nami!

  2. donna mikasa

    Tamago Sando would probably be my “go to” lunch–mainly because I LOVE Kewpie mayonnaise! Those panda picks are so adorable! I’ll check out the lunch box site.

  3. Hi Nami, thanks for visiting my blog. The tsukemono we usually find in Miami is Niitakaya.
    Thank you too for introducing Lunch-a-Porter to me.
    I love to eat this kind of sandwiches when I go to Japan, their bread and the mayo is really different. Oooh, that thick bread, for a tosto-tamago 😉 And about the Japanese mayo, is the only one we always have at home. Love it. Thanks god we can buy it in our city.

  4. Hi Nami,

    Your egg sando bento looks great. My kids also loved this type of sandwich while we were living in Japan. I never thought of giving them the same here in Canada, but now i will try it! Also, many Thanks for mentioning my site!

  5. Linda | The Urban Mrs

    Awww kewpie – that’s my favorite mayo. So simple and yet looks so delicious (and neat!). I’d love to have this too (and go shopping, lol).

  6. Hi Nami – I’m so glad to discover your blog. I love Japanese food and drool over Japanese cookbooks; it’s great to find a blog with Japanese recipes in English! I love a basic egg sandwiches and these look terrific. I’ve seen the Japanese mayonnaise before but never realized what it was! We shop at Mitsuwa sometimes here on the East Coast. : )

  7. I remember having these when I was a little girl. I LOVE crustless sandwiches cut into half. These look delicious. I love Japanese mayonnaise and prefer it over American mayonnaise most of the times. Lovely post.

  8. I love this sandwich and the bread in Japan and Taiwan bakeries are always soft and fresh! Thanks for the recipe Nami I am definitely going to make this for lunch or even my breakfast because it’s so easy hehe ~

  9. Dumpling Love

    I LOVE egg sandwiches! I always add some cucumber to it too, to add some crunch. And finely chopped carrot! My mum loves my egg sandwiches hehe =D Which reminds me, it’s been a while since I’ve made one for her…

  10. Tina Driz

    What’s the name brand of the mayo Nami? I do the same thing with my egg salad but have not tried with the japanese mayo yet my husband said it might taste different.

  11. I think most kids would prefer crustless sandwiches, or at least mine did anyways. I’m sure your son was happy with this lunch. Especially with those cute pandas in there as a surprise. I hope you and the family are doing well. Of of these days I have to get down your way.

  12. I love egg salad sandwiches too! I love how simple this recipe is. Ever since I discovered Japanese mayo, I only use it now!

    This is an adorable bento!

  13. Jayne

    Ahhh…. egg sandwich. I recently made a dill egg sandwich. Just something fabulous about the creamy creamy filling! Gorgeous.

  14. Eleanor

    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.

    • Hi Eleanor! Thank you for your kind comment! I hope you will give it a try. It’s a very simple “egg” taste with creamy mayonnaise. Hope you can find Japanese mayo too because that makes it so much better! :)

  15. The pandas are so cute!! I think the version of egg salad sandwiches I grew up with was much like yours — mine never had celery or chives or anything like that either. It’s one dish I think is best kept simple.

  16. Nami, what a fun post – we all get so busy at times that it seems almost impossible to manage all these food preparations on time but the idea of packing egg salad together with a turkey sandwich and some colorful veggies is a perfect lunch choice that kids always enjoy! I sometimes put left-over hard boiled and sliced eggs with mayo on the kids sandwiches and they love it!
    Have a great Thursday!

  17. Simplicity often makes a dish or dessert super-duper tasty. So glad you shared your Japanese classic egg salad sando, Nami-san =) The little panda are ちょう河合!


  18. awww (: Your family is so lucky, especially your son who gets the cutest bento boxes for lunch! Egg sandwich has always been one of my fav since I was young and till this day, I love to stuff it in my croissant! hehe And oldie but definitely still a goodie! x

  19. The pandas are adorable! What you call a last minute emergency lunch would be a well thought out one for some. You make every lunch and meal look like a special occasion.

  20. Kimmi

    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 Kimmi! That reminds me – my mom also made the sandwich with scramble eggs! Wow how could I forget about it. I need to make that really soon and evaluate which one is actually faster. 😀 Thanks for your kind comment. Have a lovely weekend! :)

  21. Egg sandwiches are so easy…and so good. I love making them on a day when there is nothing else in the fridge (we always have eggs!) And my goodness, don’t I just adore those little panda bears! What a fun way to make lunch more adorable. Thank you for sharing!

  22. I love how you remove the sides of the bread. It brings back a lot of good memories when my mom used to do the same. This is probably not the last time I am going to mention this here — your kids are very lucky to have a very loving mom like you. Simple bento but full of love. :)

  23. Simple, delicious and perfect for any kid. I never tried Japanese mayo, sounds Delicious and not as heavy. I love your new bento box too, looks so cute. Got to check to see what I can find for my kids. I know they would love it!

  24. What a cute lunch. I have two little children who would love a lunch like this! I love how the bread cuts neatly into three pieces to fill the bento box perfectly. I will duck over to the sponsor and check out the collection :)

  25. Marianna

    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

    • Hi Marianna! Thank you for finding my blog, and welcome! :) I’m happy to hear you enjoy my recipes already. I’m glad the alternatives I mentioned helped. I’m still (yes still….) working on the Pantry page and hope to improve it so readers can utilize the page better.

      Regarding konnyaku, I have only three recipes that I used so far on my blog:

      I highly recommend tonjiru. I need to update that picture, but if you enjoy miso soup, this is my most favorite miso soup. :)

      Hope this helps!

  26. Bams Kitchen

    I see you are almost out of your Japanese mayo.. Oh ohhh… That would be a full alarm emergency in our home. Great ideas for egg salad sandwiches as Easter is right around the corner. Totemo Kawaii bento box….your such a good mom. Take care, BAM

  27. Aruna

    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

  28. Orchidea

    This bento might be simple but it is really inviting and I would love to have it for lunch!
    In Italy when you have a picknick outside you often pack bread filled with scrambled eggs… so good. Your version of cooked eggs with mayonaise sounds really good too.

  29. Nami, don’t you think that egg dishes always bring a touch of spring? You sandwiches look so cute with the panda picks and with the beautiful yellow eggs filling… Hard-boiled egg covered with mayonnaise, salt and pepper is probably the most frequent way I have eggs and I have had this combination since I was a child. I actually prepare exactly the same egg “paste” quite often (also only eggs, mayonnaise, salt and pepper, which is the way my mum did!) and sometimes add some European chives; they bring a very pleasant fresh note.
    Thank you for offering us the 15% off!

  30. Now this is a bento box I can do for my children because egg salad is something that I can make too. :) I am going to try it. :0) I need to get those fun panda sticks for the fruit. :)

  31. My gosh….you can even make a simple egg sandwich something to die for….haha. I just feel like wanting to eat it now. But too bad, there’s no bread and no mayonnaise….hmmm. Lots of eggs though 😀

  32. Hi Nami, I love egg salad so much… it’s one of my favourite sandwiches, although normally I like to add watercress too for a bit of crunch and peppery flavour. I didn’t know US egg salad has funky stuff like celery inside. In England we just have egg, mayo, bit of seasoning too!

    When I was in Japan I found the must peculiar sandwiches in the 7-Eleven downstairs from my ex-girlfriend’s apartment… potato salad sandwich, and more strange than that… “strawberries and cream sandwich”!

  33. へえー私もこのように作ります、かなり日本的だね。耳を切るのは主人から勿体無いのクレームが。でも私は聞く耳を持ちません。Just kidding! Ha ha ha. Nice pictures!

  34. I admit I bought the Kewpie mayo at the Japanese market because it was cute, then I got addicted to it!! I love egg salad sandwiches and haven’t made them in years.

    • Thank you Alicia! Oh yes quick is right, but I’m happy that it tastes really good (thank you to Japanese mayonnaise) and I don’t mind eating often. :)

  35. I’ve started buying fresh, free-range eggs from my SIL’s friend and they are the best eggs ever. Making egg salad has totally slipped my mine until now. This bento looks SO good and has given me the idea of making one for myself this week. I have to be out of the house at lunch for 3 days and supply my own lunch so this particular bento has really grabbed my interest. Thanks Nami!!! I love your egg salad and you can’t beat homemade bread!

  36. But do you usually keep hard-boiled eggs on hand or do they get eaten as snacks? :) I’m with you though – there’s definitely nights I’m too busy so we go out to dinner but then I have to worry about what we’ll eat the next day. My husband is gone all week at a conference and considering I’ve got some Japanese mayo and eggs in my fridge I think I know what one of my quick solo dinners is going to be – thanks!

  37. Ok I have to tell you no matter how hard I try and trust me I have tried really hard my bentos never look this perfect..
    I seriously have to come n learn from you… My son will jump if I can pack such bentos for him.

    • Hi SK! Yes, you can mash the egg previous day and make into sandwich following day or even, make sandwich previous night (as long as you keep it refrigerated). This sandwich is supposed to be eaten cold or at room temperature. :)

  38. Devie

    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..

    • Hi Devie! Sure, you can make a day in advance (like previous night, preferably), but make sure to keep in the refrigerator and keep it cool till lunch time. Hope you enjoy! :)
