What is Vegetarian/Vegan Japchae?
Traditional Korean Japchae is made with a choice of protein, vegetables, and sweet potato starch noodles. Vegan japchae can be prepared with plant base protein and the rest of the ingredients are already vegan and vegetarian-friendly. The noodles are chewy-tender in texture, the vegetables are tender-crisp and it has a salty, sweet, umami flavour.
From ancient times to the present, Japchae is one of the most popular and mandatory dishes prepared and served during Korean Festivals and Traditional Ceremonies. Since it is easy to be made and tastes flavourful, Korean people love to enjoy it often on their usual days as well. It's popular not just in Korea but loved by many people across the world.
Before the cooking process starts, you need to gather and prepare the essential ingredients.
Dangmyeon ( 당면, 唐麵, Korean cellophane noodles ) - Korean glass noodles are ideal for this recipe which are made of sweet potato starch. You can also use Korean potato noodles or mung bean noodles. In the UK and in some countries we can buy sweet potato noodles only at Korean supermarkets or Amazon online. It's thicker and chewier than Chinese glass noodles and perfect for making salad, stir-fries, and soup. If you cannot find dangmyeon noodles, you can use regular cellophane noodles as a substitute.
Tofu - Add firm tofu which is great for stir-fries and rich in protein. Gently press to remove excess water and pat dry with a paper towel to absorb moisture. Then slice it into thin strips or bite-size pieces.
Vegetables - Shiitake mushroom, carrot, onions, garlic, spring onion ( green onion ), bell peppers, and spinach are ideal to make this japchae vegan recipe but feel free to add your favourite veggies.
3 Ingredients Japchae Sauce - Soy sauce, sugar, and sesame oil are 3 classic ingredients you will need. Add a dash of freshly ground pepper to your taste.
Sesame seeds - Don't forget to add toasted sesame seeds. It's one of the important ingredients to make this dish a toasty, nutty, unique authentic flavour.
