I enjoy this recipe because it brings together a perfect balance of sweet and savory flavors. I love how the sesame oil and soy sauce coat every ingredient, while the mix of vegetables adds freshness and texture. I also appreciate how versatile it is, since I can easily swap the protein or adjust the vegetables depending on what I have at home.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
2 lb thin-sliced beef or chicken, tofu, or shrimp
1 lb Korean sweet potato noodles (glass noodles)
3 medium carrots, julienned
1 large white onion, thinly sliced
1/2 bunch green onions, chopped
6 garlic cloves, minced
1/2 lb spinach leaves
4 tbsp sesame oil, divided
1 tbsp olive oil
6 tbsp soy sauce or tamari
3 tbsp brown sugar
Directions
I start by bringing a large pot of water to a boil with a drizzle of olive oil. I add the sweet potato noodles and cook them for about 5 to 6 minutes, then drain and set them aside.
In a skillet over high heat, I cook the beef until browned. While it cooks, I season it with half of the soy sauce, sesame oil, and brown sugar. Once done, I set it aside.
In another skillet, I heat the olive oil and add the carrots and onion. I cook them until softened, then I add the remaining soy sauce, sesame oil, and brown sugar. I stir in the garlic and green onions and cook for another minute.
I add the spinach and stir until it wilts. Then I combine all the vegetables and beef with the cooked noodles in a large bowl.
I toss everything together well until evenly coated and serve it warm, sometimes garnishing with extra green onions.
Servings and Timing
I get about 10 servings from this recipe.
I usually need around 1 hour total, including about 30 minutes of prep time and 30 minutes of cooking time.
Variations
I sometimes replace beef with tofu or chicken for a different twist. I also like adding mushrooms or bell peppers for extra texture. When I want some heat, I mix in a bit of gochujang or chili flakes. I can also make it fully vegetarian by skipping the meat and adding more vegetables.
Storage/reheating
I store leftovers in an airtight container in the refrigerator for up to 4 days. I find that the flavors deepen over time, making it even more delicious the next day.
For reheating, I warm it in a skillet over medium heat with a splash of water or a little oil to loosen the noodles. I can also use the microwave, but I prefer the skillet for better texture.
FAQs
Can I make Japchae ahead of time?
I often make Japchae ahead of time because it stores well and reheats nicely. I find it perfect for meal prep or gatherings.
Are sweet potato noodles gluten-free?
I use sweet potato noodles because they are naturally gluten-free, but I make sure to use tamari instead of regular soy sauce if I want the whole dish to stay gluten-free.
Can I eat Japchae cold?
I sometimes enjoy Japchae cold or at room temperature. I find it still tastes great and makes a convenient leftover meal.
What can I use instead of beef?
I like using chicken, shrimp, tofu, or even just vegetables. The recipe adapts easily to different preferences.
Why do my noodles stick together?
I make sure not to overcook the noodles and I toss them with a bit of oil after draining. This helps keep them from clumping together.
