Simple yet absolutely delicious Korean Soy Sauce Noodles (Ganjang Bibim Guksu) is every Korean kid’s favorite dish growing up. It’s nutty, salty and of course, sweet. Just need 4 seasoning ingredients besides the noodles but full of fabulous flavors. Ready in 10 min or less!!
Ganjang Bibim Guksu 간장 비빔국수 or Korean Soy Sauce Noodles (lack of a better name..) is basically Korean’s version of Butter spaghetti that you make for your little picky eaters. I loved this as a kid and now that I think about it, I think this was probably the first dish that I started making for myself (sorry, I am changing my story from making Spaghetti meat sauce as my first dish). But of course, an adult cooked the noodles for me cause I was probably like 7 or 8.
It’s such a simple dish that it never crossed my mind to share it on my blog but recently I was asked to come up with a recipe that highlights sesame oil and boy, what better dish to highlight the wonderful sesame oil than this dish!
If you asked anyone who grew up in Korea in the 70’s and 80’s, I bet you, they would all say that they grew up eating this when they were kids 😝. It’s the perfect quick lunch or afternoon snack when moms don’t feel like cooking. Kids love it because it’s a perfect balance of salty and sweet but not at all spicy (although I will share later how you can spice it up!). And usually, you don’t add any vegetables but please feel free to add a soft boiled egg, green onions, kimchi, perilla, ssukat.. whatever you wish.
For Yummy Korean Soy Sauce Noodles, Use Best Sesame Oil and Jin Ganjang (soy sauce)
Because this dish is such a simple recipe, using the best quality sesame oil and soy sauce (jin ganjang) will make a difference in flavor. You can read my Ultimate Guide to Sesame Oil and also my Know Your Soy Sauce post to find the best tasting and high-quality oil and sauce for this recipe.

Tips for storage
- While the rice is cooking, keep smelling the pot to avoid the rice from burning. Adjust fire if you think it’s burning. Try NOT to open the pot while it is cooking. Korean short grain rice are different from long grain rice and don’t do well when you open the pot while it’s cooking.
- You may think the yangnyeom jang sauce is pretty bland for Korean standards but this is how Korean Temple food is. It really tries to bring out the natural flavors of the ingredients which are mushrooms in this case. So do not make the sauce too strong/spicy because it will overpower the mushroom flavor.
- You can use regular sesame oil instead of perilla seed oil. It will be less aromatic but perilla seed oil has a flavor that not everyone likes and is also not easy to get in most countries so sesame oil should work fine.
- You are welcome to use other kinds of mushrooms, but try to use a variety of flavors and textures.
- An electric rice cooker can make your life much easier but you will probably not get the same wonderful flavor.
How to make Korean Soy Sauce Noodles (Ganjang Bibim Guksu)
| Servings: 2 | Cook Time: 8 min | Difficulty: Easy |
Ingrdients
- 200 g Somyeon 소면 (thin korean dried noodles) or 2 cups cooked thin noodles
- Sauce
- 1.5 Tbsp soy sauce (Jin Ganjang)
- 1.5 Tbsp sugar
- 1 Tbsp sesame oil
- 1/2 Tbsp sesame seeds
- 1/2~1 tsp gochukaru (korean red chili powder) – optional
- 1 green onions, sliced (optional)
Step-by-Step Instructions
- Measure dry noodles by either weighing it or by using your fingers.
Although everyone’s finger lengths are different, you can get into the habit of measuring with your fingers. For me, 2 servings is when I can fit the noodles in the circle that I make with my thumb and index finger. 
- Boil a pot of water (about 5 cups for 200g noodles). Add the dried noodles and cook on medium high per package directions. For ssal somyeon, you just need to cook for 4 minutes. Cook with no lid and if it looks like it’s going to boil over (lilke in the picture), pour about 1/2 cup of cold water and the foam will quickly go down. You may need to repeat as necessary until you reach 4 minutes.
- Prepare a big bowl of cold icy water and dump the hot cooked noodles into the cold water bath. Rinse noodles until it’s completely cooled down. Drain.
- In a bowl, add the noodles, add sesame oil, soy sauce, sugar, sesame seeds and mix well. Taste and adjust as needed.
- That’s it!! That’s all you need to do to make Korean soy sauce noodles! Optionally, add some sliced green onions or some gochukaru to your Ganjang Bibim Guksu to make a grown-up version 😝! It will add a great fresh zingy flavor that I personally like better. Here’s how that looks – I hope you try it cause it’s extra yummy!!!

Tips & Notes:
- The sodium level on this dish is quite higher than the actual dish because the noodles will lose a lot of sodium after it’s boiled in water and rinsed.
- Feel free to try other toppings to this very basic noodle dish. You can add a soft boiled egg, more cooked veggies, whatever you want to try!
- Noodles – I like to use Sempio Ssal Somyeon 쌀소면 which is gluten-free and delicious. But you can use any other thin wheat Somyeon noodles or even angel hair pasta. You can read more about Somyeon HERE.
Loved it! Simple and quick. I wanted some protein so I added leftover NY Strip steak thinly sliced to it right from the fridge.
