Below are tips on making japchae sweet potato noodles:
Thinly cut carrots and bell peppers
This will allow these vegetables to better incorporate into your noodles since they're long and slender like your noodles.
Pre-mix the sauce!
In a small bowl, mix the sauce ingredients well, until the brown sugar fully dissolves for a well-balanced taste.
Use thinly cut marbled beef for ease!
Many Asian markets carry this item in the freezer section. Or you can use any marbled beef and cut it thinly.
Use pre-washed baby spinach for simplicity!
I love using pre-washed baby spinach to make things easier in the kitchen. Any Western or Asian grocer will carry this item.
Boil the noodles until soft and chewy
In a large pot of water, bring to boil. Boil the noodles for about 5 minutes in hot water.
Use a large bowl for mixing
Have a large bowl ready to pour your strained noodles and the rest of your ingredients into.
Fry veggies together until soft but crisp
Over low heat, warm your large skillet. Then fry veggies for 1-2 minutes at most. We do not want to overcook the vegetables. So, cook at a low heat.
Sauté mushrooms, garlic and beef with Japchae Sauce
Over medium heat, add sesame oil along with garlic and mushrooms and sauté for a bit. Then add beef to the pan, spread it apart and then add a little bit of the Japchae sauce into the pan to give the ingredients extra flavor. This part will take about 2-3 minutes.
Mix everything together!
In a large mixing bowl or medium bowl, transfer everything into it including the sesame seeds and mix well with tongs or gloved hands as the noodles will be hot.
Great as leftovers
You can make this noodles dish in large quantities and store it in an airtight container for next day. To reheat the leftover japchae, microwave or stir fry on the stove top. You can serve it chilled too.
To cut the noodles
Sometimes the noodles can be pretty long to eat and serve. Use clean kitchen scissors to cut the noodles within the large mixing bowl.
Below are common questions about this easy japchae recipe:

Where can I buy Korean Sweet Potato Starch Noodles?
You can buy this item at any Korean Grocer or Asian Grocery Store.
What are Sweet Potato Noodles made of?
Sweet potatoes starch. These noodles are gluten free.
Where can I find thinly cut marbled beef?
Most Asian markets will sell thinly cut marbled beef in the frozen section. It's usually chuck or rib eye beef that has been thinly cut. It's also known as "Shabu Shabu Beef" or "Hot Pot Style Beef".
I can't find thinly cut marbled beef!
You may also use thinly cut rib eye or chuck beef with fat running through it. Freeze it for 45-60 minutes and then this will make it easier to slice into thin pieces.
Can I use other vegetables?
Sure! Feel free to use other various vegetables that suit your fancy. Aim for colorful vegetables like green onions or spring onions, wood ear mushrooms, bok choy or choy sum (or any leafy green), yellow or orange peppers, bean sprouts and more.
