Triangle gimbap with tuna

Samgak-gimbap 삼각김밥

Samgak-gimbap is a triangular shaped gimbap which is designed to keep the seaweed fresh by putting it between 2 thin sheets of plastic. So you can eat it hours later, and it will still be crispy. It was invented by a Japanese company. I think whoever thought of this was pretty clever!

To make this, you will have to buy seaweed (gim) that was made specially for samgak-gimbap. You should also get a mold for making the triangle shape, but if you can’t get one, watch the video to see how to do it without it, just using plastic wrap.

In my recipe I’m going to show you 2 kinds of filling: kimchi and tuna, but you can use your own favorite ingredients to make delicious fillings.


(for 3-4 servings, or 8-9 samgak-gimbap)

Ok, let’s start!


Prepare rice:

  1. Mix vinegar, white sugar, and kosher salt in a small bowl until the mixture looks clear.
  2. In a large bowl add the warm rice and pour the clear liquid over top. Mix it and let it cool down.

Make filling:

Make the tuna filling

  1. Open a can of tuna and squeeze out the water through a cheesecloth.
  2. In a heated pan, put 1 ts vegetable oil.
  3. Add garlic, tuna, soy sauce, and brown sugar into the pan and stir fry it for a few minutes.
  4. Turn the heat off and add 1 ts toasted sesame oil, 1 ts roasted sesame seeds, and black ground pepper.

Make the kimchi filling

  1. Chop the kimchi and put it in a small bowl.
  2. Add gochujang, 1 ts of toasted sesame oil, and 1 ts of roasted sesame seeds to the kimchi and mix it up.

Put the rice and filling in the mold:

  1. Fill ⅔ of the mold with cooked rice.
  2. Place your filling in the center, then top up the mold with rice, put on the lid, and press it down.

Wrap it up:

  1. Take out a piece of gim from the package. Don’t remove the plastic wrap, we need this! We’re going to wrap this sheet of gim with the plastic around your rice and fillings. The plastic will keep both rice and gim fresh until you are ready to eat the gimbap.
  2. Look for the numbers on the sheet. The numbers side of the sheet goes down, and #1 should be pointing away from you.
  3. Take the lid off your mold, and place the mold face down on the middle of your sheet, with the rice facing down. The tip of the triangle should be pointing away from you, towards #1. Let the rice packet gently slide out of the mold and land on the gim. Remove the mold.
  4. Fold the sheet over the rice, away from you and towards #1. Then fold up the sides. Keep the sides in place with the sticker that came with the gim.


  1. When you’re ready to eat it, look for #1 on the side of the packet. Pull that tab and the plastic will peel off.
  2. Gently remove #2 and then #3, putting the gim back into place each time.
  3. Take a bite. Crispy, isn’t it?

  6. Hi Maangchi

    I made this for a party and they all loved it! I varied the fillings from beef, chicken and tuna and even a veggie one! Thank you so much!

    Also, I tried to download this recipes as a podcast of iTunes and it doesn’t seem to work! Maybe it’s me, but what can I do because they usually just download by themselves when you add a new recipe!

    Thanks for everything!

  7. Wow, this is so awesome!
    Thanks, maagchi. :)
    I was recently introduced to samgak kimbap by my boyfriend because he loves it so much.

    Both recipes look very tantalizing!
    I’ll be on the look out for that seaweed!

    This comment has too many exclamation marks!

  8. Whoa.. This is wonderful.. I loveee ur website.. I’ll put your link on my Blog.. ^^

  9. MMM, delicious! In addition to the kimchi and tuna filling, I added spam and some teriyaki sauce, like spam musubi in Hawaii.

    Also, I found the mold and plastic wrap at Daiso stores for $1.50. It comes with an open triangle mold and 8 clear plastic sheets. You have to supply your own kim, but it’s very cheap and affordable! Refill sheets are only $1.50 for 10! So if you live in California, please check for it there!

  10. Hi, Thanks for the recipe :). I very like your cooking! I would like to know what the special kind rice you use to make the sushi in this recipe? It looks really good!

  11. I purchased the mold and wrap from the (it takes a while for the site to load).

    Thank you Maangchi for such a super simple and great recipe!

  12. I’ve been desperate for some Samgakkimbap ever since I left South Korea (on a visit). I cannot find it anywhere here in Michigan, and I’m terrible in the kitchen, but I’ll ask my husband if he’ll make this for me. If I can find a recipe for Bi Bim Man Du, I will be in heaven. Gamsahamnida!

  13. thank you for the video.. i tried to make this before but it was a failure…. now i can try again.

  14. Hi.

    I watched your video and was really interested in your recipes. I went to a Korean grocery store here in Melbourne, Australia and bought so many things featured in your ingredients sections. I just made these samgak kimbab for my friends, using canned tuna in spicy chilli sauce and it turned out really good and the seaweed sheets amazes them haha… Thanks so much, your website is great! Dinner tonight will be korean too.. kimchi chigae and ddukbokki :)

  15. 삼각김밥 너무맛있어요! 감사~ ^^
