The Korean dish of glass noodles and vegetables often served during Chuseok is japchae.
Japchae is a stir-fried dish made with dangmyeon, translucent noodles produced from sweet-potato starch. It commonly includes vegetables such as spinach, carrots, onions, and mushrooms, with sesame oil and soy sauce providing much of its characteristic flavor. Meat, especially beef, may also be added.
The dish has long been associated with Korean celebrations, banquets, and special occasions, including Chuseok. Its colorful mixture and ability to be served warm or at room temperature make it practical for large family gatherings and holiday tables.
Japchae is sometimes mistaken for a noodle soup or for a single fixed recipe. Regional and household versions vary considerably, and modern recipes may change the vegetables or protein. The key identifying feature is the chewy, translucent starch noodle combined with seasoned ingredients, not one mandatory topping.
