The first time I tried this microwave gimbugak hack, I was honestly mind blown. I’ve been finding new ways to use it ever since because it creates crispy seaweed cups without any frying or oil. (See below to learn more about gimbugak.)

This time I wanted something a little lighter and more snackable. I was craving sushi, but not enough to make an entire sushi night, so I paired the crispy seaweed cups with tuna tartare, avocado, yuzu ponzu, and a few spicy toppings.

The combination is honestly so good. The crispy seaweed cups add crunch, the tuna is fresh and savory, the avocado adds creaminess, and the yuzu ponzu ties everything together beautifully.

It feels like something you’d order as an appetizer at a restaurant, but it’s surprisingly easy to make at home.

What Is Gimbugak?

Gimbugak (김부각) is a traditional Korean snack made by coating seaweed (gim) with a starch layer before drying and frying until crispy.

This recipe uses a shortcut version made with rice paper and a microwave to create crispy seaweed cups without deep frying.

The result isn’t a traditional gimbugak, but it delivers a very similar crispy texture that’s perfect for holding toppings.

Tuna tartare with avocado, yuzu ponzu, and spicy toppings served alongside crispy seaweed cups made with a microwave gimbugak method.

Ingredients
  

Crispy Gimbugak Cups
  • 3 Gim (seaweed)
  • 3 Rice paper sheets
  • 1 tbsp Sesame seeds
  • 1 tsp Salt
Tuna Tartare
  • ½ lb Sushi-grade tuna diced
  • 1 tbsp Soy sauce
  • 1 tsp Sesame oil
  • 1 tsp Rice vinegar or lime juice
  • 1 tsp Sriracha (optional)
  • 1 Green onion finely chopped
  • 1 tsp Sesame seeds
Avocado Base
  • 1 Small avocado diced
  • Juice of ½ lime
  • ½ tsp Salt
Toppings (optional)
  • 1 tbsp Yuzu ponzu optional
  • ½ Jalapeño or serrano pepper thinly sliced, optional
  • 1 tsp Sesame seeds optional
  • Microgreens optional
  • 1 tbsp Spicy mayo optional

Equipment

  • Microwave-safe sauce bowls
  • Ring mold or cookie cutter (optional)

Method
 

  1. Make the crispy seaweed cups
    Sprinkle sesame seeds and a little salt over a sheet of gim.
    Quickly dip a square rice paper sheet in room-temperature or cold water and place it over the gim.
    Fold any excess rice paper onto the back.
    If using round rice paper, trim any excess and patch uncovered corners so the surface is mostly covered.
    Cut into 4 squares and place into small microwave-safe sauce bowls.
    Microwave for about 2 minutes, or until crispy.
    Repeat with the remaining sheets.
  2. Prepare avocado
    Toss the avocado with the lime juice and a pinch of salt.
  3. Prepare tuna tartare
    In a bowl, combine the tuna, soy sauce, sesame oil, rice vinegar (or lime juice), sriracha, green onion, and sesame seeds.
    Mix gently until combined.
  4. Assemble tartare
    Place a small spoonful of yuzu ponzu onto a serving plate.
    Set a ring mold over the ponzu.
    Layer the avocado followed by the tuna tartare.
    Carefully remove the ring mold.
    Top with sesame seeds, sliced jalapeño or serrano pepper, microgreens, and spicy mayo, if using.
  5. Serve
    Serve the tartare alongside the crispy seaweed cups.
    Spoon the tartare onto the cups just before eating to keep them crisp.

Notes

 

Difficulty

Easy – Simple ingredients and minimal prep, with an easy microwave method for creating crispy seaweed cups.

Storage

Best enjoyed fresh.
Refrigerator: The tuna tartare can be refrigerated for up to 1 day, though it is best served immediately after mixing.
Crispy Seaweed Cups: Store in an airtight container at room temperature for up to 1 day.
Freezer: Not recommended.

Tips

• For the best texture, mix the tuna tartare just before serving
• Assemble the bites just before eating so the crispy seaweed cups stay crisp
• If using round rice paper, don’t worry about making it perfect. Small patches work well and won’t be noticeable once crisped
• Jalapeño and serrano peppers both work well depending on your preferred spice level
• The spicy mayo is optional, but adds a nice creamy contrast
• Use full-size gim (seaweed) sheets made for kimbap or sushi, not individually packaged seaweed snack packs.
