Jump to Recipe


Bibim guksu is a gluten-free, Korean cold noodle salad tossed in a spicy, sweet, and tangy dressing. The thinly sliced vegetables and kimchi are easy to grab with the chilled buckwheat noodles for some crunchy, fresh bites. I also like to add some mint to make the salad extra light and refreshing for the summer.

Bibim Guksu


Bibim guksu (비빔국수) means mixed noodles in Korean. This gluten-free dish is prepared with toothsome noodles, tangy kimchi, and fresh vegetables mixed in a spicy and sweet Korean chili dressing.

This is a quick and simple recipe for a hot and lazy summer day. It is also an easy and delicious dish to share at your next summer potluck!

The only stove-top cooking that is required is boiling the noodles and (optional) egg. The assorted vegetables and kimchi are served chilled and fresh.


Noodles for Bibim Guksu

This dish is usually made with thin wheat noodles (somen, somyeon, 소면) or buckwheat noodles (maemil myeon, 메밀면).

I use thin wheat noodles in my kimchi bibim guksu, which is simpler in ingredients. For this more veggie-packed recipe, however, I like to use buckwheat noodles. These thicker noodles don’t get so lost in the sea of vegetables, and you still get some good texture and bite.

The buckwheat noodles are also gluten-free, along with all of the other ingredients in this recipe. Just make sure that the Korean fermented chili pepper paste (gochujang, 고추장) and soy sauce that you use are also gluten-free (e.g. Tamari sauce).

The noodles only take 4 minutes to cook in boiling water. I would recommend to run them under cold water right away to prevent them from further cooking and sticking together. This is also helpful because you want to serve the noodles cold along with the other chilled vegetables.

Vegetables

Bibim guksu with soba noodles is more often seen prepared with a wide and colorful assortment of fresh vegetables. The most common toppings are julienned carrot, cucumber, shredded lettuce, and red cabbage.

The cucumber, cabbage, and carrots add nice texture and crunch. I like to use a peeler to make thin shavings of carrot that I then cut into thinner strips. This gives the carrots a more delicate texture and crunch.

I always like to have some sliced kimchi in my bibim guksu. It adds some tangy crunch and a kick of spice. I recommend using kimchi that has been aged for a while as opposed to freshly made kimchi. Well-fermented kimchi has richer flavors that are more deeply infused into the kimchi cabbage.

The wide assortment of vegetables in this dish also makes it more of a noodle salad. Kimchi bibim guksu, on the other hand, has fewer toppings and is usually categorized as a noodle dish. It is usually topped with simply some sliced cucumber, kimchi, and dried seaweed.

Mint leaves

Fresh herbs such as perilla leaves (kkaetnip, 깻잎) are commonly mixed in as well. I like adding perilla, but it is only sold in some Asian grocery stores. When I want to make this dish on a whim, I like to instead add some thinly sliced mint leaves.

Mint leaves are not used in traditional bibim guksu recipes. It’s something I thought of, and I find that the flavors actually work very well together. The spicy cold noodles mixed with the cooling mint leaves makes it an extra refreshing and perfect dish to enjoy on a hot summer day.


Bibim Guksu vs Bibimbap

You may recognize that the name, bibim guksu, is pretty similar to the Korean dish called bibimbap.

They both use a gochujang-based sauce and have a variety of toppings. However, bibim guksu largely uses fresh ingredients for its toppings. The toppings in bibimbap, on the other hand, usually require some stove-top cooking. You can find my al dolsot bibimbap recipe here.

Bibim Guksu Sauce

Like bibimbap sauce, bibim guksu sauce is also gochujang-based. The fermented chili pepper paste is not only spicy, but rich with umami from the fermented soybeans that are also in the paste. Both sauces have a nutty flavor from the toasted sesame oil, subtle tang from the rice vinegar, and sweetness from the coconut sugar. However, one sauce ingredient that is unique to bibim guksu is soy sauce.

You could also add regular cane sugar, honey, or oligo syrup as sweeteners. Korean green plum syrup or maesil-cheong (매실청) is another popular sweetener. The syrup is commonly used in Korean cooking partly as a sugar substitute. It it is sweet and tangy and is used to make refreshing drinks, galbi and bulgogi marinades, kimchi, bibim guksu, and other Korean recipes.

Servings: 2

Ingredients

  • 2 servings dry buckwheat noodles (180g)
  • 1 soft-boiled egg, halved (optional, see recipe notes for directions)
  • ½ tsp toasted sesame seeds

Sauce

  • 3 tbsp gochujang
  • 3 tsp toasted sesame oil
  • tsp rice vinegar
  • 3 tsp coconut sugar
  • 3 tsp soy sauce

Toppings

  • ½ cup kimchi, thinly sliced
  • ¼ cup cucumber, julienned
  • ½ cup red cabbage, thinly sliced
  • ¼ cup carrot, thinly peeled and sliced
  • ½ cup green leaf lettuce, thinly sliced
  • ¼ cup mint leaves, thinly sliced

Instructions

  • Mix the sauce ingredients together in a small bowl.
  • Cook the noodles in boiling water for about 4 minutes or according to the package instructions.
  • Drain the noodles in a colander and run them under cold water until they are cooled. This will prevent them from overcooking and sticking together.
  • To a bowl, add a serving of noodles, toppings, and sauce. Garnish with toasted sesame seeds and serve immediately.

Notes

Soft-boiled egg:
1) Add water to a sauce pan (just enough to cover the egg by about an inch) and bring it to a boil. 2) Get an egg straight from the refrigerator and carefully lower it into the boiling water. You can gently roll it around the sauce-pan in the first couple minutes so that the yolk will be centered. 3) Let the egg could for another 5 minutes. 4) Transfer the egg to an ice bath and let it cool for 10 minutes. 5) Carefully peel the egg and cut in half lengthwise.
