Cucumber Egg Korean Recipe: Crispy Wonton Cups With Runny Yolk Streaks

This crispy Korean cucumber egg recipe delivers the perfect balance of refreshing crunch and rich, runny yolk—every bite is a harmony of textures. The secret lies in thinly sliced cucumbers wrapped in delicate wonton cups, fried until golden and crisp, then topped with a perfectly cooked egg that pools into silky, golden streaks. I developed this dish after years of experimenting with Korean bapang (egg wraps), but this version takes it to the next level with the satisfying contrast of crispy wonton cups and creamy yolk.

The beauty of this recipe is its simplicity—just a handful of ingredients come together to create a dish that’s both elegant and approachable. Wonton cups provide the ideal crispy vessel, while the cucumber adds a refreshing crunch that cuts through the richness of the egg. The key is frying the cups just until they’re golden and crisp, then sliding in the egg and letting it cook to your preferred doneness. This method ensures the wonton stays crispy while the egg transforms into a velvety, golden center.

What you’ll end up with is a plate of crispy, golden wonton cups filled with perfectly runny egg, each bite offering a satisfying crunch followed by a smooth, creamy finish. The cucumber adds a subtle freshness that balances the richness, making this dish both indulgent and refreshing. It’s the kind of recipe that feels special enough for a brunch gathering but simple enough for a weeknight treat.

Serve these crispy wonton cups with a side of gochujang (Korean chili paste) for dipping, or pair them with a light kimchi salad to add tangy brightness. The combination of textures and flavors makes this dish unforgettable—crispy, creamy, and perfectly balanced. Let’s get cooking!

Ingredients for cucumber with egg korean

Crispy wonton cups, silky yolk, and fresh cucumber—just eight core ingredients transform into a brunch masterpiece.

Wonton cups are the star here—look for thin, delicate shells at the Asian market or frozen section. Martini brand is my go-to for consistent quality, but any store-bought variety works. For homemade, use wonton wrappers and fold into cups. The cucumbers should be firm and crisp, not waxy—Persian or Kirby work best. If using regular cucumbers, peel and remove all seeds to prevent bitterness. Keep everything cold until frying—room temperature ingredients won't crisp properly.

No wonton cups? Spring roll wrappers work in a pinch, but they'll be slightly thicker. Can't find Persian cucumbers? English cucumbers work too, just halve lengthwise. For the dipping sauce, swap gochujang for sriracha mixed with rice vinegar if needed. The sesame seeds can be omitted if you're short, but toast them in a dry pan for 30 seconds to deepen their flavor. Egg freshness matters—use eggs no older than 1 week for perfect runny yolks. And if you're feeling fancy, add a pinch of white pepper to the eggs for subtle depth.

Store wonton cups in the freezer until ready to use—they crisp better straight from frozen. Cucumber slices should be prepped right before frying to maintain crispness. The fried cups keep 20 minutes at room temperature before the wontons soften, so work quickly or keep them warm in a 200°F oven. For make-ahead prep, fry the cups, cool completely, then reheat in a 350°F oven for 5 minutes before adding eggs. The dipping sauce stays fresh 1 week refrigerated, so double it for future use.

Step-by-step instructions for crispy wonton cups with runny yolk streaks

Master this Korean-inspired technique for perfect crispy wonton cups with silky egg yolks.

Cut the 1 whole Persian cucumber lengthwise into 8 thin slices, removing seeds carefully with a spoon. The slices should be about ⅛-inch thick for even cooking. Pat each slice dry with paper towels—this ensures they crisp up nicely in the oil. Arrange them on a plate and sprinkle lightly with the 0.25 cup all-purpose flour, shaking off any excess. This creates a delicate barrier that helps them hold their shape during frying.

I like to work quickly here—don't let the cucumber sit too long after cutting or it'll release too much water. The flour coating also prevents the slices from sticking together in the oil later. Keep them covered with a clean towel until ready to fry, but no longer than 10 minutes before cooking.

Heat the 2 cups vegetable oil in a deep skillet or wok over medium heat until it reaches 350°F. Use a thermometer to monitor—this is crucial for even cooking. Gently place the floured cucumber slices into the oil, working in batches if needed to avoid overcrowding. Fry for 1 to 1.5 minutes per side until golden brown and crispy. They should puff up slightly and develop a delicate crunch.

Don't walk away during this step. The oil temperature drops quickly when you add food, and undercooked cucumbers will turn soggy. You'll know they're done when they float to the surface and develop small air pockets. Transfer them immediately to a paper towel-lined plate to drain excess oil. Keep them warm in a 200°F oven while you prepare the eggs.

Crack the 4 whole large eggs into a bowl, season generously with the 0.5 tsp salt and 0.25 tsp black pepper, then whisk lightly until just combined. Heat a non-stick skillet over medium-low heat and add just enough oil to lightly coat the bottom. Pour in the eggs, tilting the pan to distribute evenly. Cook for 2 to 3 minutes until the edges set but the centers remain completely runny.

Here's the secret: the eggs should still jiggle slightly when you shake the pan. They'll continue cooking from residual heat when you transfer them to the wonton cups. Remove from heat just before they're fully set—you want that signature Korean runny yolk experience. Slide each egg onto a plate and let cool for 1 minute before assembling.

Place each crispy cucumber cup on a serving plate and nestle an egg into the center. Drizzle with 1 tbsp sesame oil and sprinkle with 1 tbsp toasted sesame seeds. For the dipping sauce, whisk together the 0.25 cup gochujang and 2 tbsp rice vinegar until smooth. Serve immediately with the sauce on the side and the 0.5 cup kimchi for a complete experience.

This dish is all about contrast—crispy cucumber cups, silky egg yolks, and the bold flavors of the gochujang sauce. The kimchi adds a tangy balance that cuts through the richness. Serve with chopsticks for the full Korean dining experience, letting diners dip the crispy cups into the sauce before enjoying the runny yolk.
