Method

1

Season the rice

PT0M

In a small bowl, mix the water, rice vinegar, sugar, and salt until the sugar and salt dissolve. Fold this mixture into the freshly cooked rice using a rice paddle or spatula, using a cutting motion to avoid mashing the grains. Spread the rice out on a large plate or in a wide bowl and let it cool to room temperature, uncovered. The rice should be cool enough to handle but still slightly warm.

2

Prepare the tuna filling

PT5M

Drain the canned tuna well, then flake it into a bowl. Add the mayonnaise, gochujang (if using), sesame oil, and soy sauce. Mix until the tuna is evenly coated. Adjust the seasoning to your taste—add a little more gochujang for extra kick or a pinch of salt if needed. Set aside.

3

Season the spinach

PT5M

Blanch the spinach in boiling water for 30 seconds, then immediately transfer to ice water to stop cooking. Squeeze out excess water and coarsely chop. In a small bowl, mix the spinach with the minced garlic, 1 teaspoon sesame oil, and a pinch of salt (if needed). Toss well and set aside.

4

Cook the carrot

PT3M

Heat 1 tablespoon of vegetable oil in a skillet over medium heat. Add the julienned carrot and sprinkle with salt. Stir-fry for 2–3 minutes until the carrot is slightly softened but still crisp. Transfer to a plate to cool.

5

Make the egg strips

PT5M

In a small bowl, beat the eggs with a pinch of salt. Heat a lightly oiled nonstick skillet over medium-low heat. Pour in the egg and swirl to create a thin, even layer. Cook until just set, about 2 minutes, then flip carefully and cook for 30 seconds. Slide onto a cutting board and slice into thin strips (about 1/4 inch wide).

6

Assemble and roll

PT15M

Place a nori sheet on a bamboo mat with the shiny side facing down. Spread about 3/4 cup of rice evenly over the nori, leaving a 1-inch margin at the top edge. Lay a row of tuna filling, then a row of spinach, a row of carrot, a row of egg, and a row of pickled radish across the middle of the rice. Lift the mat and roll the seaweed over the filling, tucking it in firmly with your fingers. Continue rolling to the end, then press gently to seal the roll. Repeat with the remaining ingredients to make 4 rolls.

7

Slice and finish

PT5M

Brush each roll lightly with sesame oil and sprinkle with toasted sesame seeds. Using a sharp knife, cut each roll into 1/2-inch thick slices. For clean cuts, wipe the knife with a damp cloth between slices.

Tips

  • Use short-grain rice (sushi rice) for the best texture, long-grain rice will not stick together well.
  • Cool the seasoned rice completely before rolling to prevent the nori from becoming soggy.
  • Wet your hands lightly with water or sesame oil before touching the rice to prevent sticking.
  • Tightly pack the filling and press firmly when rolling to keep the gimbap intact when slicing.

Serving suggestions

  • Serve tuna gimbap as a main dish with a side of pickled radish and maybe a bowl of Korean soup like miyeokguk (seaweed soup). It pairs beautifully with a little soy sauce mixed with a drop of sesame oil for dipping. Gimbap is also perfect for packed lunches, picnics, or as a snack.
