What is Japchae

Japchae is a popular Korean dish that’s loved even by those unfamiliar with Korean cuisine. It is typically one of the first dishes that people are introduced to when learning about Korean food. Traditionally, it is a dish reserved for special occasions such as holidays, celebrations, and parties due to the time and effort required to properly prepare it. This involves soaking the noodles for several hours, cooking and seasoning each individual vegetable and protein separately. It’s easy to see why this dish was originally reserved for special moments.

Japchae literally means “a mixture of vegetables.” Originally, this plant-based dish was enjoyed by royals without the translucent sweet potato noodles and meat. The absence of meat in the dish was due to the major influence of Buddhist beliefs at the time. It was only after 200 years that the noodles and meat were added to the original vegetarian dish. This change occurred after Mongols brought wheat, buckwheat, and sweet potatoes to Korea. This transformed the dish into what we now know as “Japchae.”

How to Make Delicious Japchae

The secret to its delectable taste lies in the sauce and the texture of the noodles. Trust me, you don’t want to miss out on this chewy yet soft and translucent noodle dish.

Ingredients

☑️ Japchae Noodles (Sweet Potato Glass Noodles): Also known as Sweet Potato Glass Noodles, they are made from sweet potato starch and are naturally gluten-free. They have a slightly chewy texture and become translucent when cooked. You can find dehydrated sweet potato glass noodles easily in any Asian grocery store. It is recommended that you soak the noodles for about 20-30 minutes prior to cooking. This helps to reduce the cooking time and allows the noodles to better absorb the sauces without swelling when they get cold. Ensure that the noodles are fully submerged in water while soaking. If you prefer, you can skip soaking and boil the noodles as per the package instructions. After soaking, the noodles are ready to be cooked with the prepared sauces.

☑️Mushroom: For a plant-based dish, mushrooms are a great meat alternative due to their texture and bite. Shiitake, pearl, and oyster mushrooms, among others, are good options as they stay firm when cooked. Use a damp cloth to clean them instead of washing, to remove dirt.

☑️Black fungus or wood ear mushroom: Black fungus and wood ear mushrooms are two different types of mushrooms that share many similarities. These mushrooms are commonly used in Asian cuisine, particularly in Chinese dishes, and have a jelly-like consistency that provides a distinctive chewiness. Before using them, they need to be soaked for around 15 minutes until they become soft. When soaked, they expand to about 3-4 times their original size, so it’s best to use small amounts. If you’re making a plant-based Japchae, which lacks substantial chewiness due to the absence of meat, feel free to add a bit more. I personally add around 10 pieces of these mushrooms to enhance the texture. Personally, I love the texture of these mushrooms and highly recommend adding them to your dishes.

☑️Vegetables: When cooking vegetables, it’s best to choose firmer ones with less water content, such as carrots, capsicum, onion, and spinach. If you’re adding leafy greens, put them in at the end and for a shorter period of time. The key is to cook for a short time quickly so that they still remain vibrant in colour and crunchy in texture. To make the vegetables look more aesthetically pleasing, julienne them into similar shapes like noodles or match sticks. If you don’t have a spiralizer, just julienne the carrot. When sautéing, start with aromatic vegetables like onions, then add harder vegetables like carrots and capsicum, and finally spinach at the last minute. Don’t forget to add a little salt while sautéing, or else the vegetables won’t be seasoned enough, even if you add sauce later. Traditionally, each vegetable is sautéed separately and spinach is blanched beforehand. However, adding the vegetables at the last minute can prevent them from becoming brown and wilted.
