• Get ready to whip up this refreshing dish with these essential ingredients!
For the Noodles
- Somyeon Noodles – Thin wheat noodles that provide the perfect base; substitute with rice noodles for a gluten-free option.
For the Sauce
- Gochujang – This Korean red chili paste adds the signature spicy depth; no direct substitute, but sriracha can offer a different twist.
- Gochugaru – Korean red pepper flakes enhance both heat and color; feel free to replace with paprika if you prefer a milder flavor.
- Soy Sauce – Boosts umami richness; tamari is a great substitution for a gluten-free recipe.
- Sesame Oil – Infuses nutty notes and depth; olive oil is an acceptable alternative if needed.
- Rice Vinegar – Balances the sauce’s sweetness with its acidity; apple cider vinegar works well as a substitute.
- Garlic – Minced for aromatic flavor; adjust the amount based on personal preference.
- Honey – Sweetens and balances the heat; use agave syrup to keep it vegan-friendly.
- Toasted Sesame Seeds – Perfect for garnish and added crunch.
For the Toppings
- Cucumber – Fresh and thinly sliced for that much-needed crunch; radish or zucchini can be substituted for a unique touch.
- Soft-boiled Egg – Optional but adds protein; simply omit for a vegan-friendly dish.
- Kimchi – Adds an extra kick and fermentation benefits as a delicious optional garnish.
Step‑by‑Step Instructions for Bibim Guksu
Step 1: Make the Sauce
In a medium bowl, combine 2 tablespoons of gochujang, 1 tablespoon of gochugaru, 2 tablespoons of soy sauce, 1 tablespoon of sesame oil, 1 tablespoon of rice vinegar, minced garlic, and honey to taste. Whisk the mixture vigorously for about 2 minutes until it’s well blended and smooth. Set the bowl aside, allowing the vibrant flavors to develop while you move on to the noodles.
Step 2: Cook the Noodles
Bring a large pot of water to a rolling boil over high heat. Once boiling, add 200 grams of somyeon noodles and cook according to the package instructions—usually about 4-5 minutes. As they cook, stir gently to prevent sticking. When they’re tender yet slightly chewy, drain the noodles and rinse them under cold water for 1-2 minutes to stop the cooking process and cool them down.
Step 3: Combine the Noodles and Sauce
In a large mixing bowl, add the cold somyeon noodles to the prepared sauce. Using tongs or your hands, gently toss the noodles with the sauce for about 1-2 minutes, ensuring every strand is evenly coated with the fiery red mixture. The vibrant color of the sauce will envelop the noodles, making them look irresistible.
Step 4: Prepare the Toppings
While the noodles sit coated in the sauce, thinly slice half a cucumber and prepare a soft-boiled egg if desired. To soft-boil, gently place the egg in boiling water and cook for exactly 6-7 minutes, then transfer to ice water to halt cooking. After a few minutes, peel the egg. Set the cucumber and egg aside, ready for the final assembly.
Step 5: Serve and Garnish
Divide the delicious Bibim Guksu among serving bowls. Top each bowl with the sliced cucumber, gently halved soft-boiled egg, and a sprinkle of toasted sesame seeds for added crunch. If you like, add a side of kimchi to enhance the flavors. Serve the dish cold and enjoy every flavorful bite!

Bibim Guksu Recipe FAQs
How do I choose the right somyeon noodles?
Absolutely! When selecting somyeon noodles, look for thin, delicate wheat noodles that are typically found in Asian grocery stores. Check the package for a slightly translucent appearance, indicating freshness. If gluten-free is your goal, rice noodles are a great substitute!
How should I store leftover Bibim Guksu?
Very good question! Store any leftover Bibim Guksu in an airtight container in the refrigerator for up to 3 days. It’s best enjoyed cold, as reheating may diminish the flavors and texture. Just remember to toss it again before serving, to ensure every strand is coated in that delicious sauce.
Can I freeze Bibim Guksu?
Yes, you can! Although it’s best enjoyed fresh, if you want to freeze it, store the sauce separately in a sealed container or bag for up to 1 month. Then, you can prepare fresh noodles when you’re ready to indulge. Always mix fresh noodles with the thawed sauce and toppings just before serving for the best experience!
What if I find the sauce too spicy?
No worries! If you find the gochujang or gochugaru too spicy for your taste, start by using half the recommended amounts. You can always add more. Additionally, balancing the heat with a splash of more rice vinegar or a little more honey can help mellow out the spice while enhancing the flavor profile!
Are there any dietary considerations for Bibim Guksu?
Absolutely! Bibim Guksu is vegan-friendly as it’s made without any animal products. Just be cautious with the optional soft-boiled egg and use agave syrup instead of honey for a fully vegan dish. If you have allergies, ensure that the soy sauce is gluten-free (use tamari) and double-check the ingredients in your gochujang.
How do I prevent the noodles from sticking together?
Great question! To prevent the somyeon noodles from sticking, stir them gently while cooking to ensure they separate. After draining, rinse the noodles under cold water for about 1-2 minutes to cool them down and remove excess starch. This will help keep them beautifully silky when you mix them with the sauce!
