Tips for Making the Best Spicy Korean Noodles
Below, find a collection of tips and tricks to help you make the best spicy Korean noodles.
- Slice the beef against the grain. To prevent your beef from turning tough, always slice it against the grain. If you’re unsure what “against the grain” means, it refers to the direction that the muscle fibers run through a cut of beef. You always want to slice against the muscle fibers versus alongside them. This breaks up the fibers and makes beef easier to bite and chew.
- Saute the veggies in batches. To prevent your veggies from overcooking, prepare them in batches.
- Use a wok. A wok is perfect for making stir-fried noodles. The high edges prevent spillage and also allow you to push up the more cooked bits away from direct heat.
- Adjust the spice level to your liking. Depending on your preferred level of spice, add more or less sriracha and crushed red pepper flakes. When you make the sauce, taste it as you go to adjust the level to your liking.
Serving Spicy Korean Noodles
Serve these spicy Korean noodles for a quick weeknight dinner or bring them to your next potluck. They’re feeling enough on their own, but if you want to make a full-on spread, whip up some Korean-style chicken thighs or pork ribs in the air fryer. Also, don’t forget to pick up a bottle of kimchi. This fermented, spicy cabbage is hugely popular in Korean food and is often served as a side dish or topping. If you love sauerkraut, you’ll adore kimchi!

Looking for ways to store spicy Korean noodles for later? We’ve done the testing for you. Here’s what we found.
- Refrigerator: Store leftover spicy Korean noodles in an airtight container in the refrigerator. They should keep for up to 5 days.

Reheating Tip: Reheat your Korean noodles in the microwave for a minute or two.

IngridJul 14, 2023 Any suggestions for a spinach substitute? It’s a hard one because of the volume shrinkage and texture.
Natalya DrozhzhinJul 14, 2023 Hi Ingrid, The spinach in supposed to shrink in volume and most greens will do the same thing when cooked. However, if you don't prefer the texture, feel free to omit it.
CandiceJun 8, 2022 As a Korean-American, this is so cringe. Sriracha isn’t Korean, you should be using gochujang. Please if you’re looking for Korean recipes, use recipes written by actual Koreans. Maangchi, or Korean bapsang.
JoDec 19, 2023 As a Japanese-American, I was never hung up on actual authencity of the dish. Some of the best dishes are Asian fushion dishes.
RachelNov 14, 2023 Only in America does anyone care whether one’s country’s version of a recipe is authentic. But…gochujang is delicious.
DavidJul 3, 2022 After making it tonight, I agree on the gochujang. Also, cut the sesame oil at least in half, and add some garlic. I think the backbone here is great but it's way too much sesame oil in my opinion.
Natalya DrozhzhinJul 3, 2022 Thanks for the feedback, David!
Natalya DrozhzhinJun 9, 2022 Hi, Candice! Thank you for taking the time to comment. This recipe was given to me by a coworker, and this is how her family made it. I understand that not every ingredient may be fully authentic or the way that you would make it. We love my coworkers recipe nonetheless. 🙂
CandiceJun 10, 2022 Is your coworker Korean? I’ve never heard of a Korean noodle dish using glass noodles and sriracha. Glass noodles are used for japchae, which is not a spicy dish. And again, sriracha is not a Korean ingredient. I think maybe you should just rename this recipe as a spicy noodle dish and not call it Korean.
ChannahJul 7, 2022 Korean ingredients aren’t always easy to find, so maybe it was used as a substitute. I have no clue. But I think we can just appreciate this recipe for its own charm and if you don’t like it. Don’t use it. 🙂
GinoApr 11, 2022 What do I put for the sauce
Natalya DrozhzhinApr 11, 2022 Hi Gino- the sauce ingredients are also listed in the recipe card!
GisellaJul 28, 2021 Delicious! I have a question, I always use "stir fry" meat from Whole Foods for my stir fry's however i'm always ending up with a ton of juice while initially cooking the meat. Do you have any tips to avoid that because it ends up just cooking the meat fully instead of searing? None of the recipes i've followed mention anything about that. Thanks!
Natalya DrozhzhinJul 28, 2021 Hey Gisella, this happens when you overcrowd the pan. I would cook less meat at a time or use a larger pan. Enjoy
MichelleJun 17, 2021 This looks yummy. I have a question, what if I just want to make it w/o meat, just noodles and veggies. How would I deviate from this?
Natalya DrozhzhinJun 17, 2021 Hey Michelle, you totally can. Just skip the step with the meat part. Add extra veggies this way the sauce is balanced.
SherryMar 20, 2021 Do you start with 1 lb of dry glass noodles or is it 1 pound after they are cooked? The packages are usually very small (3.5 oz) and you end up with about 1 lb noodles after cooked.
See Also75 Best Easy DinnersNatalya DrozhzhinMar 21, 2021 Hey Sherry, we use 1lb of uncooked noodles. Sometimes I add fewer noodles and more veggies. Hope this helps
Kailey HillFeb 2, 2021 This recipe was amzing my grandma and I loved it
Natalya DrozhzhinFeb 2, 2021 I'm so glad you both enjoyed the recipe, thank you for taking the time to comment!
박나리Feb 1, 2021 Is there a substitute for the brown sugar?
Natalya DrozhzhinFeb 1, 2021 Yes, you can use regular sugar.
柴萨迪Feb 1, 2021 I love it so much and thanks for your recipe❤

Natalya DrozhzhinOct 23, 2020 I hope you love the recipe, circle back and let me know how it went!
ChristyFeb 19, 2020 Can you use rice noodles instead of glass noodles?
Natalya DrozhzhinFeb 21, 2020 Rice noodles can get a bit mushy and I wouldn't recommend them for this recipe. The texture of the noodles is what makes this dish amazing. You can purchase them in most Asian food markets or even amazon.
EmilySep 21, 2019 How do you make the noodles?
Natalya DrozhzhinSep 23, 2019 Hi Emily, I typically purchase the noodles. Haven't tried making them.
LindaFeb 14, 2020 She means how do you cook the noodles. Typically Asian glass noodles have no cooking directions, at least in English.
Natalya DrozhzhinFeb 14, 2020 Linda, that makes sense now. Thanks for helping out. We boil the glass noodles for about 5 minutes and run it under right after they are drained.
LeeJul 25, 2019 What kind of beef do you use
Natalya DrozhzhinJul 25, 2019 Hi Lee, I like to use any lean beef cuts that I can slice very thinly. Cuts like sirloin or top round steak would work great!
ValentinaFeb 22, 2019 These spicy noodles are going to be amazing for our monthly ladies party. We're all about that Asain food. Can't wait to try it.
Natalya DrozhzhinFeb 22, 2019 I hope you all will love them! They do reheat really wells so it would be perfect!
DinaFeb 19, 2019 I have an undeniable love for Asian stir fry noodles. These Korean spicy noodles look so delicious! My husband is going to love this Asian noodle recipe!
Natalya DrozhzhinFeb 19, 2019 Dina, my husband loves it too and doesn't even complain about all the veggies. We love a good noodle recipe!
KatyaFeb 19, 2019 I love all the veggies that you added to these korean spicy noodles! It looks like the most perfect easy weeknight meal.
Natalya DrozhzhinFeb 19, 2019 Thank you Katya. It a good way to hide a ton of veggies in one dish.
MadiJul 2, 2020 How do you make the carrots look like that? We have just been shredding them but I want to make them how it’s pictured. Could you please share your secret with me?🙏🏼
Natalya DrozhzhinJul 2, 2020 I purchase shredded carrots. I love using them for noodles recipes, not so much for salads.
Julia Frey@VikalinkaFeb 18, 2019 I am putting these Korean noodles on my regular rotation. They look perfect for a quick midweek dinner!
Natalya DrozhzhinFeb 19, 2019 Yes, they reheat really great too. Next day lunch is covered! Its a win win 🙂
