Delicious Beef Japchae, A Korean Glassy Noodle Stir Fry

Japchae is a well known Korean glassy noodle stir fry of sweet potato starch noodles with vegetables and beef and can be enjoyed as a side dish, snack, or main entree. It’s easy to prepare ahead of time for a quick weeknight supper or potlucks. One can easily adapt the recipe to be vegan, gluten free, or top 8 allergen free.

Delicious Beef Japchae

Japchae is one of my favorite dishes. After many years of “please try a bite” my kids now love it too and asked me to make it at home. I recently made it for the first time and because Chef Keith Norman, the food allergy savvy chef at South Point Hotel, saw a photo of my dinner on Facebook, he asked if he could share the recipe at FAACT’s Teen Conference in a cooking demo. He is a treasure to the food allergy community so I have been working hard to support the event.

 

The sweet potato vermicelli noodles or dangmyeon noodles are flavorful with a slippery but chewy texture. The vegetables taste fresh and tender crisp. The dish tastes hearty with slices of beef but can also be vegan by omitting the beef. It’s a dish that could be prepped or made in advance, making it perfect for a potluck or an easy weeknight meal to reheat and serve. The best thing about learning to make it, is that we can customize it according to our allergies and preferences.

What are sweet potato starch noodles and how do I buy them?

  • Sweet potato starch noodles are made from a thick slurry of sweet potato starch extruded into boiling water. The noodles look grey and opaque after they are dried. But when they are cooked, the noodles look transparent and are sometimes referred to as glassy noodles or cellophane noodles because of its appearance.

  • Sometimes the noodles are also called vermicelli because of their long slender threads. However it’s important not to confuse them with rice vermicelli or wheat vermicelli which are not cellophane noodles. Sweet potato noodles are usually grey dry noodles in big bulky packages about 12-18 inches in length.
  • I felt overwhelmed at a Korean supermarket because they stock at least a dozen different brands of sweet potato noodles. I eventually found a name brand product which I like but the downside is that I haven’t heard back from the Korean company that makes the noodles.
  • I also shopped at an Asian market closer to home and they stock just a few different choices of sweet potato starch noodles. The two different distributors, Walong Marketing and Wang Globalnet, were very helpful and confirmed with their manufacturers in Asia that the facilities only make sweet potato noodles.

  • In case you do not have an Asian market near you, I also looked at the product availability on Amazon and noticed that the Assi brand of sweet potato noodles are distributed by Rhee Brothers. I have reached out to them about allergen information and they are helpful. Affiliate link  (thanks for your support!)

Additional sweet potato noodle buying tips

  • Typical ingredients are sweet potato and water, stick to the kind with those two ingredients. Some are made with sodium alginate, which is apparently a bulking agent. Avoid any that mention alum.
  • Better quality sweet potato noodles will be lighter in color.
  • If you have a choice between buying a small package or a large package, buy the smaller one. Unless the noodles are portioned into smaller bundles it’s hard to use half a package or reseal a large open bag. The first time I made japchae I ended up cooking an entire 1 kilogram bag for that reason.
  • 12 ounces dry noodles make 4.5 cups of cooked noodles and with additional ingredients, it will make enough for 4 servings as a main entree or 6-8 servings as a side dish.

Allergy Aware Asian Fare

  • Even though the sweet potato noodles are most likely top 8 free, gluten free, and paleo, please read the ingredient list and contact the manufacturer if you are sensitive to cross contact and traces of other allergens. The two products pictured above are made in a sweet potato noodle factory that only handles sweet potatoes.
  • If you happen to be allergic to sweet potato, then use a chewy and sturdy (not mushy) noodle that is safe for you. I have some brands that are in my cupboards listed in this post under Asian Noodles. I tried Explore Asian’s Edamame and Mung Bean Fettucine (contains soy) as a variation of this recipe and it was good, the pasta has a mild flavor and the texture held up adequately. BGreen Foods also has some nice chewy noodles that are free of top 8 allergens (per phone call last year). Results may vary if you don’t use sweet potato noodles, it won’t be japchae but you will still have an allergy safe Asian inspired meal, win-win!
  • The thinly sliced beef that is used for bulgogi is traditional but one could also wrap and freeze a good rib eye or sirloin steak for 30 minutes and then thinly slice it. Or one could use pork or chicken instead or simply omit for a vegan variation.
  • Soy sauce and sesame oil are important seasoning ingredients for this dish. Know that results may vary if one omits them or uses a different ingredient. There are lots of great soy sauce alternatives and I have a soy free soy sauce recipe made with beef bouillon that would be great for this dish. I tried using coconut amino to see how it would taste and the resulting dish tasted better with a touch of salt. It also doesn’t look the same as japchae seasoned with soy sauce.

Japchae seasoned with coconut amino looks lighter and tastes sweeter, adjust seasonings accordingly if you use coconut amino.
  • Toasted sesame oil is much harder to substitute in an allergy friendly way. Nut oils taste similar but are not suitable for a nut free diet! The oily top layer of a sunflower seed butter has a similar roasted nutty taste as sesame oil but I think it would just ruin the rest of the sunflower seed butter. I tried a cold press sunflower seed oil, and the taste is too mild tasting. I just learned about perilla oil as a substitute for sesame oil, so I will update you when I try it.
  • This dish uses a lot of colorful vegetables which is perfect for a healthy snack or meal. I learned that it’s traditional to include foods that are green, red, yellow, white, and black. Spinach, carrots, red bell peppers, onions, and shitake mushrooms are typical vegetables for jap chae.
Allergy aware Asian fare means that we adapt recipes to make traditional foods safe to eat. I’m not an expert at Korean cuisine, but it was interesting for me to learn more. Due to our family’s food allergies, I omit red bell peppers and shitake mushrooms, used celery instead, and included in the “notes” section how to use mushrooms and bell peppers. Enjoy!

Not bad for a first try at making beef japchae! I like the texture of the carrot ribbons (pictured) better than shredded carrots.

This recipe as written is free of peanuts, tree nuts, dairy, fish, shellfish, and eggs. It can easily be adapted to free of the top 8 allergens by using a soy free soy sauce or to be wheat and gluten free by using a gluten free tamari soy sauce or other soy sauce alternatives.

  1. Hi Sharon,

    you have no idea how much I am a Korean food fan. And my bestie is Korean and every now and then she volunteers to come and cook for us. And this is most of the time what she prepares and I love it. Thank you for all the detailed explanation and your photo is absolutely inviting 🙂

    • Hi Dan, it took me awhile to work up the courage to try making japchae, so I thought I would share how to make a super easy dish. I think that the sweet potato noodles are also considered paleo friendly too since it’s a grain-free, vegetable based pasta. Win-win!
