FAQs
Can I make Bibim Guksu ahead of time?
It’s best to prepare the noodles and sauce separately and combine them just before serving to maintain the noodles’ texture and freshness.
What can I use if I don’t have gochujang?
If gochujang is unavailable, mix a bit of chili paste or hot sauce with a touch of miso paste and a small amount of sugar as a substitute, though the flavor will differ slightly.

Ingredients
Noodles
- 8 oz somyeon noodles (thin wheat noodles)
Sauce
- 3 tablespoon gochujang (Korean red chili paste)
- 2 teaspoon gochugaru (Korean red chili flakes)
- 2 tablespoon soy sauce
- 2 tablespoon sesame oil
- 2 tablespoon rice vinegar
- 3 cloves garlic (minced)
- 2 1/2 tablespoon honey
- 1 tablespoon toasted sesame seeds (crushed)
Garnishes
- 1 cucumber (thinly sliced)
- 1 soft-boiled egg
- Additional toasted sesame seeds
- Kimchi (to taste)
Instructions
- Make the sauce: In a mixing bowl, combine the gochujang, gochugaru, soy sauce, sesame oil, rice vinegar, minced garlic, honey, and crushed toasted sesame seeds. Stir well until the sauce is smooth and evenly blended. Set aside to allow the flavors to meld.
- Cook the noodles: Bring a large pot of water to a rolling boil. Add the somyeon noodles and cook according to the package instructions, usually around 3-4 minutes, until tender but still firm. Immediately rinse the noodles under cold running water and then submerge them in ice-cold water to stop the cooking process and chill them thoroughly. Drain well.
- Combine: Place the drained cold noodles in a mixing bowl and pour the prepared sauce over them. Toss gently but thoroughly until every strand is coated evenly with the spicy sauce.
- Serve: Transfer the sauced noodles to a serving bowl. Garnish with thinly sliced cucumber, a halved soft-boiled egg, a generous sprinkle of toasted sesame seeds, and a side of kimchi. Serve immediately and enjoy the harmonious balance of spicy, sour, sweet, and savory flavors.
Notes
- For an authentic flavor, use Korean gochujang and gochugaru available at Asian grocery stores.
- You can adjust the spiciness by varying the amount of gochugaru and gochujang.
- Soaking the noodles in ice water after cooking ensures they remain firm and refreshingly cold.
- Soft-boiled eggs should have a slightly runny yolk; cook for about 6-7 minutes for perfect consistency.
- Kimchi adds a spicy, tangy crunch—use your favorite type or substitute with pickled vegetables if desired.
- This dish is best served immediately to maintain the texture and chill of the noodles.
