Korean Glass Noodles Recipe
Make Korean Glass Noodles Recipe: soak dangmyeon, toss with savory sauce, and serve glossy noodles with beef and veggies.
Ingredients
- 8 ounces (225 g) dried Korean sweet potato glass noodles (dangmyeon)
- 8 cups (1.9 L) very warm water at 120–130°F (50–55°C), for soaking the noodles
- 6 tablespoons (90 ml) soy sauce
- 3 tablespoons (36 g) packed light brown sugar
- 2 tablespoons (30 ml) toasted sesame oil, plus 1 teaspoon (5 ml) for finishing
- 4 cloves garlic, finely minced (about 4 teaspoons / 8 g)
- 1 teaspoon (3 g) finely grated fresh ginger
- 1/4 teaspoon (0.5 g) freshly ground black pepper
- 1 large egg (about 50 g), at room temperature
- 1 teaspoon (5 ml) neutral oil (such as canola or grapeseed), for cooking the egg garnish
- 6 ounces (170 g) beef sirloin or ribeye, very thinly sliced across the grain
- 1 small yellow onion (about 5 ounces / 140 g), thinly sliced
- 1 medium carrot (about 3 ounces / 85 g), peeled and cut into thin matchsticks
- 1 medium red bell pepper (about 6 ounces / 170 g), cored and thinly sliced into strips
- 4 ounces (115 g) fresh shiitake mushrooms, stems removed and caps thinly sliced
- 5 ounces (140 g) fresh spinach leaves, rinsed and drained
- 3 green onions (about 1 ounce / 30 g), cut into 2-inch (5 cm) pieces
- 1 tablespoon plus 2 teaspoons (25 ml) neutral oil (such as canola or grapeseed), for stir-frying
- 1 teaspoon (5 g) kosher salt, divided
- 1 teaspoon (4 g) granulated sugar
- 1 tablespoon (9 g) toasted sesame seeds, for garnish
Instructions
Step 1: Soak the dangmyeon until translucent and pliable
Place the dried Korean sweet potato glass noodles in a large heatproof bowl and cover with very warm water, stirring once or twice as they soften. Describe the noodles as they swell and turn translucent but still retain a slightly chewy core; when they’re pliable and glossy, drain and let them rest so excess water can run off. This step emphasizes the springy, slippery texture of the noodles and the clear gelatinous sheen that signals readiness.
Step 2: Whisk the savory-sweet sauce and prep the egg ribbon
In a medium bowl, whisk soy sauce, packed light brown sugar, toasted sesame oil, minced garlic, grated ginger, and black pepper until the sugar mostly dissolves and the mixture becomes deeply glossy and homogeneous. Crack and beat an egg in a small bowl until completely smooth, then cook into a very thin pale-yellow sheet, cool briefly, roll, and slice into feather-light ribbons to reserve as a delicate garnish. Keep the sauce in the same bowl you used to whisk it so its glossy surface and tiny suspended garlic bits remain a visual anchor for the next steps.
Step 3: Marinate the beef briefly
Toss the very thinly sliced beef with a portion of the prepared sauce in the same medium bowl so the meat is lightly glossed and slightly darker along every edge. Let it rest at room temperature long enough to absorb aroma and color—this creates thin, semi-translucent shadings where the sauce penetrates and the beef fibers relax before cooking.
Step 4: Prep and organize the vegetables
Thinly slice onion, cut carrots into crisp matchsticks, slice red pepper into glossy strips, thin-slice shiitake caps, rinse and drain spinach, and trim green onions. Keep each vegetable in its own small pile or shallow ceramic bowl: the onion’s soft rings, carrot’s matte-orange sticks, pepper’s shiny crimson ribbons, mushroom’s velvety brown slices, and spinach’s damp, deep-green wilt. Season the blanched spinach lightly so it appears slightly glossy and compact in a small bowl.
Step 5: Cut and drain the noodles for easy tossing
After draining the soaked noodles well, use scissors to shorten them to manageable 8–10 inch lengths and let them rest in the colander until no excess water beads on their surface. The strands should lie semi-separated, glossy but not sticky, individual translucent ropes awaiting final seasoning.
Step 6: Showcase the cooked components off-stove
Present the results of high-heat cooking as finished elements laid out on the marble: seared beef pieces with browned edges and glossy juices, softened translucent onions and crisp-tender carrot sticks, browned shiitake slices with shiny caps, and pepper strips that remain bright and glossy. Arrange each component in small piles or low bowls to control visual rhythm and keep the pan absent from the scene.
Step 7: Toss the noodles with the sauce until glossy and deeply seasoned
Combine the well-drained noodles with half the sauce and toss until every strand is coated and turning a deeper caramel-brown sheen; then add the remainder of the sauce so the noodles become uniformly glossy and elastic. The surface should read as warmly glistening strands with tiny flecks of garlic and sesame oil pooling lightly between them.
Step 8: Gently fold in beef, vegetables, spinach, and finish with sesame oil
Lower the heat (conceptually), return the cooked beef, all vegetables, seasoned spinach, and green onions to the glossy noodles and toss gently until everything is evenly distributed and steamed-warmed. Finish with a delicate drizzle of toasted sesame oil and a final toss so the aroma perfumes the surface and a thin sheen clings to every ingredient.
Step 9: Plate and garnish for serving
Transfer the mixed glass noodles to a warm shallow serving platter chosen to hold elongated strands without burying them; top with thin egg ribbons and a scatter of toasted sesame seeds, presenting a mosaic of glossy brown noodles, bright vegetables, and delicate yellow ribbons. Serve warm or at room temperature.
Notes
- Soak noodles in very warm water until translucent but still slightly chewy to avoid mushy texture.
- Reserve a spoonful of sauce before tossing to adjust seasoning after mixing.
- Store sauce separately if you expect leftovers to keep noodles from soaking up too much flavor.
- Reheat quickly in a hot skillet with a splash of water or reserved sauce to revive gloss and texture.
- Thinly slice beef across the grain for the most tender bite.
