Spicy Tuna Mayo Rice Pockets (Onigiri Style)

These Spicy Tuna Mayo Rice Pockets are one of my favorite quick meals to make when I have leftover rice and a can of tuna in the fridge.

The folded shape is inspired by a popular Korean snack sometimes called jeogori kimbap because the finished shape resembles a jeogori (저고리), the traditional Korean jacket worn with hanbok. At the same time, the triangle shape also reminds me a little of onigiri, which is why I often describe them as onigiri-style rice pockets.

What I love most about this recipe is how simple it is. The spicy gochujang rice, creamy tuna mayo, cheese, gim, and lettuce come together with just a handful of ingredients, but the combination is surprisingly satisfying.

The cheese also serves a practical purpose by helping hold the folds together, creating a portable rice pocket that’s easy to pack for lunch, picnics, or a quick snack.

What is Jeogori?

A jeogori (저고리) is the traditional Korean jacket worn with hanbok.

Some people call these folded rice pockets jeogori kimbap because the overlapping cheese pieces resemble the crossed collar of a jeogori. Once folded, the shape creates a look that’s similar to the jacket’s signature front closure.

Prep Time 10 minutes
Servings: 3 rice pockets
Course: Snack
Cuisine: Korean

Ingredients
  

Rice
  • 1½ cups Cooked short-grain rice
  • 2 tsp Gochujang (Korean red pepper paste)
  • 2 tsp Sesame oil
  • 2 tsp Sesame seeds
Filling
  • 1 Small can tuna (5.29 oz / 150g) drained
  • 3 tbsp Mayonnaise
Other Ingredients
  • 1½ sheets Gim (seaweed) cut diagonally into 3 large triangles
  • 3 Lettuce leaves
  • 3 slices Cheese each cut diagonally in half

Method
 

  1. Season rice
    In a bowl, mix the cooked rice with gochujang, sesame oil, and sesame seeds until evenly combined.
  2. Make filling
    In a separate bowl, combine the drained tuna and mayonnaise.
    Mix until smooth and evenly combined.
  3. Assemble
    Place a triangle of gim shiny side down.
    Add a lettuce leaf in the center.
    Top with about ½ cup of the seasoned rice and gently flatten it into a triangle shape.
    Make a small indentation in the center of the rice and add one-third of the tuna mayo mixture.
  4. Add cheese
    Place one triangle of cheese on each side corner of the gim, leaving about ¼ inch peeking out past the edge.
    The exposed cheese creates the signature collar-like look once folded.
  5. Fold
    Fold the bottom corner up over the filling first.
    Fold the two side corners inward to create a sealed triangle pocket.
    Press gently so the cheese helps everything stick together.
  6. Serve
    Enjoy immediately, or wrap individually for an easy snack, lunch, or picnic meal.

Notes

Easy – Simple ingredients and no cooking required.

Storage

Best enjoyed fresh.
Refrigerator: Up to 1 day wrapped individually and stored in an airtight container.
Freezer: Not recommended.
Tip: Assemble shortly before serving for the best texture.

Tips

• Leave a small portion of the cheese exposed when assembling. Once folded, the cheese resembles the crossed collar of a jeogori, which is where the name jeogori kimbap comes from.
• Drain the tuna well so the filling doesn’t become watery
• The cheese acts like an edible “sticker” that helps keep the folds sealed
• Any sliced cheese works well here. I used American cheese, but cheddar, provolone, mozzarella, or other sliced cheeses can be used
• Try swapping the tuna mayo for salmon, crab, or other fillings you enjoy
• Use full-size gim (seaweed) sheets made for kimbap or sushi, not individually packaged seaweed snack packs.
