Why this recipe works
Crazy good sauce.
This recipe begins with an unbelievably good sauce that puts hard-hitting ingredients on display.
Korean superstar ingredient gochujang adds a spicy umami funk, soy sauce savory depth, toasted sesame oil nutty richness, and mirin a complex sweet tang. Every bite is bursting with just the right amount of spice, savoriness, and tang.
Incredible texture.
The combination of sticky, lustrous gochujang, rich toasted sesame oil, and syrupy mirin creates a sauce that perfectly clings to the noodles. While you can use any noodle, fresh or frozen udon noodles take this dish to the next level with their bouncy, supple, and slurpable texture.
Big flavor, easy to make.
While you will definitely find restaurant-worthy flavors here, this entire dish comes together in just 30 minutes. No fancy methods or tools are needed, either.
You can stop cravings in their tracks by making a double batch of the gochujang sauce. Keep it in your fridge for at least a week, and pull it out when you’re craving saucy, spicy noodles in a hurry!
Ingredient notes
The crave-worthy flavors in this recipe come from a handful of Korean and Japanese ingredients.
Gochujang
Gochujang is a Korean staple and one of my favorite ingredients. A fermented chili paste that’s spicy, subtly sweet and tangy, and deeply savory, it’s made of gochugaru (Korean chile flakes), fermented soybeans, glutinous rice, and salt (read more about gochujang here!). It’s the backbone of my Korean Cucumber Salad as well as the sauce for these noodles.
Substitute: There is no substitute that has the same supercharged flavors of gochujang. Gochujang isn’t typically gluten free, so seek out a gluten-free variety if you need to (the brands Sempio and Chung Jung One sell GF options).
Check out the FAQ section for more details on where to buy gochujang.
Soy sauce
Just like gochujang, this builds another layer of umami-richness, making the sauce irresistibly tasty.
Substitute: You can use tamari or gluten free soy sauce if you’re gluten free.
Toasted sesame oil
Used often in Korean cooking, toasted sesame oil gives the sauce a nutty flavor and rich mouthfeel.
I’ve tried a lot of brands, and this toasted sesame oil is hands down my favorite (affiliate link).
Mirin
This is a type of Japanese fermented rice wine that lends deeply funky, tangy, and slightly sweet flavors, as well as a rich body to the sauce.
Where to buy: Mirin is sold at many well-stocked grocery stores (it may be labeled as Aji-Mirin, which means “tastes like mirin”), in East Asian markets, and online.
Substitute: Use rice vinegar if you can’t find mirin. Rice vinegar isn’t sweet like mirin though, so use more brown sugar (2 TBSP instead of 1.5 TBSP). If you don’t have either, Bon Appetit suggests using dry sherry, marsala wine, or white wine vinegar.
Brown sugar
This adds the necessary sweetness to the sauce, taming the heat from the gochujang and enhancing the savoriness. You can use coconut sugar, but we don’t recommend using a liquid sweetener like maple syrup or agave, as it will thin the sauce out.
Udon noodles
Fresh or frozen udon noodles always came out on top when testing this recipe. No surprise there! Just like in my 15-Minute Vegan Chili Garlic Noodles, they came out bouncy, chewy, and slurpy every time, and never left too much sauce behind.
Udon noodles are a type of thick Japanese wheat noodle made from just flour, water, and salt. Both fresh and frozen noodles work well here.
Where to buy: You can find udon noodles at East Asian markets in the refrigerated or frozen section. You may also find shelf-stable, vacuum-sealed udon noodles at these markets.
Substitute: If you can’t find them, use dried udon noodles or another noodle variety that isn’t too thin (thin noodles, like rice vermicelli, will wilt under the weight of the sauce). Even Italian pasta, like linguine or spaghetti, will work well, despite its unconventionality.
When subbing dried noodles, the weight of noodles will be different, so check out the Tips section!
Vegetables
Go ahead and get creative here – any quick-cooking vegetable works great. I love this dish with shredded Napa cabbage and/or red bell peppers, but check out the Variations section for more suggestions.
Step-by-step instructions
Cook the noodles according to the package instructions, but cook for 1 minute less than the package instructions to prevent a soggy dish.
Drain, reserving some noodle water, and set aside.
Next, make the gochujang sauce by whisking the gochujang, toasted sesame oil, soy sauce, mirin, sugar, and gochugaru in a bowl.
Heat the oil in a large skillet over medium-high heat. Once hot, add the scallion whites and greens, garlic, and ginger, as well as vegetables like bell peppers or broccoli.
Sauté for a few minutes, then add delicate vegetables like Napa cabbage, bok choy leaves, or snow peas. Stir fry until crisp-tender.
Pour the gochujang sauce into the pan along with the sesame seeds. Next, add the cooked noodles and toss to coat. If needed, add a splash of noodle water to help bring the sauce together.
Tip: You shouldn’t need to add noodle water if using fresh or frozen udon noodles. It’s more likely you’ll need to add it if using dried noodles.
Take off the heat and garnish with reserved scallion greens and Thai basil or cilantro. Gently toss, then enjoy!
Tips for making this recipe
Follow these helpful tips before putting the noodles and sauce together:
Udon noodles: fresh vs. dried
While both fresh and dried noodles will yield the same results, you’ll need to adjust the amount you use depending on the variety you choose:
Fresh udon noodles = use 16 ounces (450g)
Frozen udon noodles = use 24 ounces (680g) (they’re heavier)
Dried udon or other dried noodles = use 8 to 9 ounces (230 to 250g)
Save the noodle water
That starch in the leftover noodle water will help your sauce cling to the noodles, especially if using dried noodles. Set a bowl underneath your colander so you don’t forget to save some water!
Use roasted or toasted sesame seeds
The sesame seeds need to be toasted or roasted ahead of time to bring out their full flavor. You can buy pre-roasted sesame seeds at many grocery stores and Asian markets, but it’s easy to toast them yourself.
Just heat a frying pan over medium heat for a couple minutes, then add the sesame seeds. Toss occasionally until they’re lightly golden and slightly fragrant, about 3 to 4 minutes.
Make a trip to your Asian market
Your local Asian market will have some or all of these ingredients, especially the gochujang, mirin, and udon noodles. Using the proper ingredients also means you’ll have an easier time achieving the best flavors and textures… All while having fun exploring new cuisines!
Pro tip: Pick up some Thai basil if you see it! It adds incredible flavor as a finishing ingredient here.
Variations
You can customize these gochujang noodles quite a bit!
Swap out the vegetables
Pick one vegetable or use half the amount of two vegetables!
Napa cabbage: 6 to 8 cups or handfuls, thinly sliced (~250g)
Bell peppers: 2 medium, thinly sliced (red, yellow, or orange)
Snap peas or snow peas: 8 to 9 ounces (230-250g), ends trimmed
Baby bok choy: 2 heads (3 if small); leafy tops cut into 1” pieces; cut white stems into 1” or bite-sized pieces
Broccoli: 8 ounces (230g), chopped very finely
Add your favorite protein
Serve gochujang noodles with your favorite protein, like baked or fried tofu, stir-fried tempeh, or store-bought pre-baked tofu.
Here’s my go-to method for simple baked tofu. To keep things efficient, bake the tofu in the oven while you cook the gochujang noodles.
- Preheat the oven to 425ºF/218ºC. Line a rimmed sheet pan with parchment paper.
- Slice a block of extra-firm tofu into 4 vertical slabs, and gently press down on them with a towel several times to remove excess water. Press for 10 minutes, changing the towels in between.
- Chop the tofu into ~ ¾ inch (2 cm) cubes.
- In a large bowl, add the tofu, 1.5 TBSP neutral-flavored oil, 1 tsp kosher salt, and black pepper to taste, tossing to coat. Add 2 TBSP potato starch (or arrowroot powder), and as gently as possible, toss with your hands.
- Arrange tofu on the pan in a single layer, spreading out the pieces so they don’t touch.
- Bake for 15 minutes, or until lightly golden on the bottom. Flip with a spatula or carefully turn the tofu with your hands. Bake for 15 minutes until golden and crisp.
Frequently Asked Questions
You can buy gochujang at Korean and large Asian markets, like H-mart. It’s also carried at well-stocked grocery stores, like Whole Foods, or online (affiliate link).
Remember: You’re looking for traditional gochujang, which is a thick paste and is typically sold in a plastic tub. Don’t buy “gochujang sauce” like this.
Some gochujang brands also offer differing heat levels. It’s pretty spicy as-is, so skip the ones labeled “extra hot” if you’re worried about spice.
Yes, it can be made gluten free with a few substitutions. (1) Seek out gluten-free gochujang*, (2) use tamari instead of soy sauce, and (c) use a relatively thick rice noodle variety (thin varieties will wilt under the sauce).
* I know the brands Sempio and Chung Jung One sell GF options.
It’s spicy enough that you’ll have a little sweat on your brow (depending on your tolerance).
If that sounds like it will be too spicy for your taste, reduce the amount of gochujang to 1 1/2 to 2 tablespoons and omit the gochugaru (Korean chile flakes, which are optional).
Sure. You can add in an extra cup of veggies if you’d like!
The leftovers can be stored in an airtight container in the fridge for up to 6 days (more likely 4 days if using dried noodles).
If you really want to save time, whisk the gochujang sauce together and keep it in a sealed jar in the fridge until it’s time to make the noodles.
You can reheat the leftover noodles and sauce quickly in the microwave or in a skillet over medium heat. Add a splash of water if you need to help loosen the texture of the sauce.

Gochujang Noodles
Ingredients
- 16 ounces (450g) fresh udon noodles (see Note 1 for subs)
Gochujang sauce
- 3 tablespoons gochujang (see Note 2)
- 1 tablespoon toasted sesame oil
- 2 tablespoons soy sauce (use tamari for GF)
- 2 tablespoons mirin (or rice vinegar)
- 1 ½ tablespoons organic brown sugar (see Note 3)
- 1 tablespoon gochugaru (optional)
Aromatics and vegetables
- 1 heaping tablespoon neutral-flavored oil
- 1 bunch (about 6) scallions, whites and light greens chopped into 1-inch pieces (dark green tops sliced thinly on a bias, reserved for garnish)
- 4 garlic cloves, finely chopped
- 1- inch piece ginger, grated or minced
- 6 to 8 cups (or handfuls) thinly sliced Napa cabbage (250g) OR 2 medium bell peppers, thinly sliced (see Note 4)
- ¼ cup (32g) roasted white sesame seeds (see Note 5)
Finishing
- A few handfuls of Thai basil leaves (or fresh cilantro, chopped)
- A drizzle of toasted sesame oil
Instructions
- Cook the noodles according to the package, but cook for a minute less to avoid a soggy dish. For fresh udon noodles, add to a pot of boiling water and cook for 1 minute; use a chopstick to loosen the noodles from their bundle and cook for another 30 seconds.
- Scoop out some noodle water, then drain the noodles.
- Make the sauce. Whisk together the gochujang, toasted sesame oil, soy sauce, mirin or vinegar, sugar, and gochugaru if using. Set aside.
- Cook the aromatics. Heat the oil in a large frying pan over medium-high heat. Once shimmering, add the scallion whites and greens, garlic, and ginger (and bell pepper, if using). Season with a pinch of salt and cook for 1 to 2 minutes over medium-high heat. If using Napa cabbage, add it now; season with a pinch of salt, and stir-fry for 3 minutes, or until it reduces in size and is tender but not soft.
- Add in the gochujang sauce and the sesame seeds and allow to sizzle. Add in the cooked noodles and use tongs to coat them in the sauce. If it feels dry, add a spoon or two of noodle water to bring the sauce together (more likely the case when using dry noodles; fresh udon noodles usually don’t need the water). Cook for 1 to 2 minutes, or until the sauce clings to the noodles.
- Off the heat, stir in the Thai basil and a drizzle of toasted sesame oil.
Notes
- This is equivalent to about 24 ounces (680g) frozen udon noodles, or 8 to 9 (230 to 250g) ounces of dried udon or wheat noodles of choice.
- Prefer only moderate heat? Use 2 tablespoons of gochujang instead.
- If using rice vinegar instead of mirin, use 2 tablespoons of sugar, as mirin is slightly sweet. You can sub with coconut sugar as needed but I don’t recommend a liquid sweetener like maple syrup or agave, as it will thin out the sauce.
- Or, you can use a combination of both Napa cabbage and bell peppers, like we did in this photo (4 cups shredded cabbage + 1 bell pepper).
- If your sesame seeds aren’t roasted, toast them first for the best flavor. To do so, heat a frying pan over medium heat. After a minute or two, add the raw sesame seeds. Toss occasionally until lightly golden, 3 to 4 minutes.

This was really good, if little spicy as I just followed the original recipe. I would definitely recommend to make 1.5x the recipe for 3 people as I served this to friends for dinner and the portions were very small even after adding tofu. Really tasty though :)
Hi B, we appreciate the review. We’re so happy to hear that you enjoyed the gochujang noodles!
This was SO YUMMY. Simple and delish, the only bummer is that it was a pretty light 3 servings and I wanted more! I added the cabbage, 2 bell peps, and two small heads of broccoli and it felt like it barely hit 3 servings. Would double it next time or add in a side.
Hi Molly, thanks for sharing! We’re happy to hear you enjoyed the recipe.
Spicy yet good! I have been dyin to try this recipe and after my heb plus had fresh udon noodles I bought 2 7oz pkgs and bam less than 30 mins jad a spicy Asian meal. Im currently dealin w allergies so hopin this dish helps treat them! Used only 2 tbsp will see if I can do 3 next time!
Hi Brenda, thank you so much for your kind review!
Made this with 600g of fresh udon. Was delicious!
Thanks for the lovely feedback, Charlotte!
Amazing weeknight recipe! So easy and feel like I could do so many combinations. I added tofu for some protein. Delish!
We’re so happy that the noodles turned out well for you, Angela. Thank you for taking the time to leave a comment and for trying out the recipe!
Absolutely delicious. Did the tofu as you suggested and threw in some bean sprouts along with the peppers, and it was so good. After both of us polishing off two bowls each, I mentioned to my partner (who is a man of few words) that it was a new recipe and he said, “Keep that.” I think we have a winner :) As neither of us is vegan or veggie, we had a runny egg on top (as so many Korean dishes tend to do) and it was absolutely delish. This will be on regular rotation. Might try buckwheat noodles next time…I feel like this would even be good cold, maybe?
Hi J, great to hear this dish is a new staple in your household! Let us know how it goes if you try it cold/with buckwheat noodles :)
Love, love, love this recipe–it’s in our regular rotation and we never have leftovers because we eat every last drop. This recipe has converted my 9 year old into liking spicy food! We like to joke that we don’t have “baby mouths” anymore!
Hi Sara, thank you so much for your kind review! Cool to hear this recipe converted you all from babymouths to spice-lovers! :)
This is sooo good! Perfectly sweet and spicy! I left out the gochugaru but did use the full three tablespoons of gochujang. I’d say the spicy level was on par with Frank’s hot sauce if I had to make a comparison. Next time I think I’ll try two tablespoons of gochujang and one tablespoon of the gochugaru. And there definitely will be a next time!
Thank you for the awesome recipe!
Hi Rica, Thank you so much for such a fantastic review! Appreciate you taking the time!
just made this – another winner❤️🔥❤️🔥❤️🔥
Thank you for your lovely comment, Linda! It makes us happy to know that you enjoyed the recipe.
This is delicious! I reduced the gochujang to 2 Tbsp which was good for my family. It didn’t taste particularly spicy, yet all of our noses were running in a good way :) I subbed 3 baby boy choi for the cabbage and used bucatini noodles, since I didn’t have udon, and these worked perfectly. We also added a full recipe of the Seriously Delicious Marinated Tofu from this site which was… seriously delicious and made the dish much more filling with the extra protein (obviously). Surprisingly, even after adding 16oz of tofu, it still seemed like there was enough sauce for our noodles. The only minor tweak I would make is to saute only about 1/3 of the scallions at the beginning in order to have more to sprinkle on top for serving. But that was just our preference. I will definitely be making this again!
Hi Madison, thanks for the lovely words! Thanks for sharing your experience :) The marinated tofu sounds like a delightful addition to these noodles.
Made this recipe with bell peppers, bok choy, broccoli and mangetouts. A keeper for sure!
Thank you for your lovely comment, Liz! It makes us happy to know that you enjoyed the recipe.
I’m obsessed with these hot-and-sweet noodles. Don’t skip the udon — they have a perfect, slurp-able texture that further elevates this delectable dish!
Wow, I can feel your enthusiasm about this recipe through the screen! Love it, Callan!
Easy and very flavorful! I added a block of pan fried tofu.
Sounds great, Maple! Thanks for leaving a review!
Seeing this made in the youtube site was inspirational and one day I might actually be able to track down some guochujang. I’ve had to make do with adding a blitzed dried pepper to the tofu in a lot of oil, cooking it long slowly, turning up to blitz the fine veg, and adding miso paste into the liquid blend. The result was both painfully spicy and disturbingly addictive: it would be nice to think some of the protein in the tofu is still beneficial.
Tom, So glad to hear you loved this recipe! We’re glad the subs worked well for you :)
Another absolutely amazing recipe! I made this for a Saturday dinner instead of getting take-out and it hit the spot! I didn’t realize how much I missed Korean food until I made this. Delicious!
Hi Laini, Thank you so much for such a fantastic review! Appreciate you taking the time!
HOOKED! I have made this once a week since I found this recipe and making it for a crowd of guests tonight. Easy and Delicious
Thanks for the lovely feedback, Jayasree!
Favorite recipe I’ve made in a while! Next time going to add even more hearty veggies, this was the perfect spiciness level for me and came together so quick and easy!!
Awesome, Jamie. Thanks for your comment and for taking the time to review!
I’ve made this recipe a couple of times now. It’s absolutely delicious. I’m wondering… could it also be made with soba noodles? I know it wouldn’t be exactly the same, but I’m trying to up my fiber intake.
Hi Steve, That wouldn’t our my choice, as the flavor of buckwheat will come through and compete with the sauce. I would recommend other high fiber pasta such as whole wheat linguine. Here’s a cool article I found that goes over fibrous noodles and gives you a bunch of options to check out. I’d recommend choosing a long noodle rather than a short one, for slurping purposes!
Super delicious! I also added tofu for protein.
Thanks for sharing, Daniil!
I’m not one to alter recipes but out of curiosity I added some tahini to the sauce and was soooo pleased with the result. Very umami and delicious. But pretty great without the addition, too. Thanks for all the wonderful recipes I’ve been learning from you!
Yum, Shira! Tahini is definitely an underrated ingredient, glad that turned out well for you :)
