Triangle-shaped rice packet wrapped in dried seaweed sheets

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 filling.


(for 3-4 servings, or 8-9 samgak-gimbap)
Cooked rice (about 4 cups), vinegar, white sugar, kosher salt, seaweed for samgak-gimbap, a can of tuna, soy sauce, garlic, toasted sesame oil, roasted sesame seeds, black ground pepper, kimchi, and hot pepper paste.

Ok, let’s start!

Prepare rice:

  1. Mix 1 tbs vinegar, 2 ts of white sugar, ¼ ts of kosher salt in a small bowl until the mixture of liquid looks clear.
  2. In a large bowl, put 4-5 cups of fresh made warm rice and pour the clear liquid into the rice and mix it and cool down.

Make filling:

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 1 clove of minced garlic, the tuna, 2 ts of soy sauce, and 2 ts of brown sugar into the pan and stir it for a few minutes.
  4. Turn the heat off and add 1 ts toasted sesame oil, 1 ts roasted sesame seeds, and ¼ ts of black ground pepper.

Kimchi filling

  1. Chop ¼ cup kimchi and put it in a small bowl.
  2. Add 1 ts of hot pepper paste, 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 the mold about 2/3 full with cooked rice.
  2. Place your filling in the center.
  3. 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! Look for the numbers on the sheet. The numbers side of the sheet goes down, and #1 should be pointing away from you.
  2. Take the lid off your mold, and place it face down on your sheet. The tip of the triangle should be pointing away from you, towards #1. Let the rice packet gently slide out on to the sheet.
  3. Fold the sheet over the rice, away from you and towards #1. Then fold up the sides. Keep them in place with the sticker that came with the gim

Eat it:

  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?

    These look delicious and are so inventive. Do you have any suggestions for other fillings? I can think of a few Japanese-style ones, but not enough!

    Thanks so much for all your work.

      Your expression “not enough” sounds cool!
      You can use mushrooms (chopped and sautee with seasoning), chopped bulgogi, chopped yellow pickled radish (danmuji), …

    If I make them the night before, will they still taste ok for the next day’s lunch? Should they be put in the refridgerator?

    I can’t wait to try making this!
    When I went hiking during my trip in Korea I loved taking kim-bap with me, and eating it at the top of the mountain – kind of like a reward. Samgak kimbap is also great for lunch-on-the-go because it’s so easy to transport and doesn’t spoil easily.

    Thanks for the recipe and in instructions – I’m off to the market now…..

    I had no idea you could get the prepared seaweed in stores! How fantastic. I first had a Japanese version of this at the Amsterdam airport and couldn’t believe how well the packaging worked! The plastic keeps everything clean and peels away in the most ingenious manner! Leave it to the Japanese!

    Great! Last week i happen to have the triangle shape wraps and mold in my hands, but i didn’t know how to work these, now i know and i can’t wait to try them soon.
    One question though, can you maybe use some water to stick the kim together so the kims don’t get undone when unwrapping?

    Great video again Maangchi!
