These veggie noodles, known as janchi guksu, are a light Korean noodle soup often served on special occasions. The dish uses thin wheat noodles in a clear broth, topped with simple vegetables. Janchi guksu traditionally appears at celebrations, which is why the name translates to “banquet noodles.” This version keeps the focus on clean flavors and gentle textures, making it easy to enjoy as a meal any time of year.
The broth stays clear and savory, made from kelp, onion, and radish. The broth complements the noodles without overpowering them. The toppings add contrast and color. Soft carrots and zucchini sit alongside kimchi, roasted seaweed, and sesame seeds. Everything gets arranged carefully in the bowl, so each bite has a little bit of everything. The noodles remain delicate, while the vegetables add freshness and bite.

For the rest
- MAKE THE BROTH: In a large pot, bring 8 cups of water to a boil with the dashima, onion, radish, and soy sauce. Reduce the heat and simmer for 45 minutes. Strain the broth through a fine-mesh sieve and reserve the liquid, discarding the dashima and veggies.
- WHILE THE BROTH IS COOKING, PREPARE THE TOPPINGS: In a medium skillet or wok, heat the olive oil and sesame oil over medium-high heat until shimmering, about 1 minute. Add the carrots and sauté until they are soft and bright orange, about 2 minutes. Season with ½ teaspoon of the coarse salt and then remove the carrots from the pan. In the same pan, add the zucchini and sauté for 3 to 4 minutes. Season with the remaining ½ teaspoon salt and then remove the zucchini from the pan.
- Bring a large pot of water to a boil. Cook the somyeon according to the package instructions, then drain and rinse under cold water to stop the cooking process. Divide the noodles evenly into four bowls. Add the warm broth and top with the carrots, zucchini, gyerranmari, kimchi, and roasted seaweed. Garnish with sesame seeds and a drizzle of dressing to serve.
