Tuna Sandwich

Chamchi sandwich 참치 샌드위치

I’m very happy to share my tuna sandwich recipe with you today. I’ve been making this simple but delicious sandwich for years and years, even when I lived in Korea. Western-style sandwiches are popular in Korea for lunchbox items.  Every time I made them my friends in Korea wanted to know the recipe, and as you see in the video my friends in LA like them, too!

The secret to this sandwich is to use a lot of fresh green vegetables to keep it light and refreshing. Fresh cucumber in particular will keep it cool and crisp, and I just love the smell of it. Many Americans use pickles to the same effect, but I prefer cucumbers.

Mayonnaise is not a traditional Korean ingredient but it is used in many ways especially when we make sandwich. We also use it for Korean-style fruit and vegetable salad and potato salad. If you like these recipes, then someday I’ll make a video for them! Happy cooking!


(makes 2 sandwiches):

  • 4 slices of multi-grain bread, toasted
  • 1 hard-boiled egg, shelled
  • 8.8 ounces of canned tuna in oil or water (1 can of Korean tuna is the perfect size)
  • ½ cup seedless cucumber, chopped
  • ¼ cup chopped onion
  • ½ teaspoon kosher salt
  • ¼ cup mayonnaise
  • 4 leaves of lettuce or  thick iceberg lettuce leaves, washed and pat dried with paper towel
  • ½ cup radish sprouts, washed and pat dried with paper towel
  • ¼ teaspoon ground black pepper

  1. Combine the cucumber and onion in a small bowl with the salt. Let it sit for 5 minutes, then put the mixture into a cotton cloth or strong paper towel and squeeze out the excess water. Put it into a mixing bowl when finished.
  2. Drain the oil (or water) from the tuna. Put it into a strainer and press out even more, then put it into the mixing bowl with the cucumber and onion.
  3. Add the egg, kosher salt, mayonnaise, and ground black pepper. Mix all the ingredients well and make sure the egg gets broken up into small pieces.tuna-sandwichtuna-sandwich.mixing
  4. Toast, grill, or pan-fry 4 pieces of multi-grain bread until the surface of the both sides turns slightly brown and crunchy.
  5. Place 2 slices of  bread on the cutting board. Add a few leaves of lettuce to each slice of bread. Divide the tuna mixture into 2 and spread it to each slice of bread. Add radish sprouts and a piece of bread to the top. Cut them into halves and serve.

    Looks good but I think that it might be tooo healthy for me! :-)
    Sometimes I like to throw in some chopped capers or some sweet chopped crunchy pickles (my own) and then other times I flavor it with some curry powder to Add another dimension.
    I have a feeling that I have backed into a great little website here! Thanks for the recipes.

    What a bad Korean I am! I’ve been making this sandwich using celery only. Never thought about using chopped cucumbers for that sweet crunchy texture and taste! And you know what, I have all the ingredients to make a couple tomorrow! I also have homegrown tomatoes and sweet peppers to add on top as well. Thank you for this fabulous recipe, Maangchi! I love this video with beautiful outfit of yours. I just bought the coin scarf at th Greek festival and have worn at Oktoberfest too. Now I see you can wear that any time, even on top of pink tutu!! Fantastic!!!

    Oh Maangchi you are such a celebrity now!! Gonna make this for lunch tomorrow, I’m guessing it’ll go great with red pepper flakes, too! How about this korean style potato salad? I would very much like that :)

    Hi Maangchi – another scrumptious recipe! I used to have with green bell pepper, mayo and little mustard – I now learnt adding the egg and more green veges. Much full and healthier option. I will definitely try one day. JY
