If you're in the mood for something light yet satisfying, comforting but refreshingly different, Ganjang Guksu (간장국수) is the perfect quick meal. Translating to soy sauce noodles, this humble Korean dish is a pantry-friendly go-to for busy days or lazy evenings when you want something delicious in under 15 minutes. It’s savory, slightly sweet, and full of textures from crisp lettuce to silky noodles—all tied together with the earthy aroma of perilla oil.
Ganjang Guksu is a Korean noodle dish centered around a simple soy sauce-based dressing. While it’s not as internationally famous as bibimbap or japchae, this dish is a quiet staple in many Korean households—especially in the summer. It’s often served cold or room temperature, and it’s incredibly flexible: you can dress it up with seasonal vegetables, protein, or just enjoy it as-is.
The version I’m sharing today features a comforting mix of sautéed zucchini, fresh lettuce, crispy seaweed flakes, and a fried egg—making it a complete one-bowl meal. But the real star here? The perilla oil, which gives the dish a uniquely nutty, herbal depth that sets it apart from other soy-based noodles.
The secret ingredient in this dish is perilla oil—and it’s not just another cooking oil. Made from roasted perilla seeds (a relative of the mint family), it has a nutty, slightly grassy flavor that’s incredibly aromatic and uniquely Korean. Unlike sesame oil, which is deeper and toastier, perilla oil feels lighter and earthier.
Can’t find perilla oil? No problem. While the taste won’t be quite the same, a good-quality sesame oil can still deliver a rich, nutty flavor that complements the soy-based sauce beautifully.
Ganjang Guksu is the kind of meal that’s as comforting as it is customizable. Whether you’re in a rush, cleaning out your fridge, or just craving a light and umami-rich dish, this Korean soy sauce noodle bowl is always a good idea. It’s fast, fresh, and incredibly satisfying—proof that simple ingredients can still pack a flavorful punch.
Slice the zucchini into thick matchsticks. In a small pan, heat 1 tbsp perilla oil and sauté the zucchini with minced garlic for 2–3 minutes until just tender. Remove and set aside. This adds a gentle sweetness and umami base to your bowl.
Using the remaining oil in the pan, fry an egg to your liking. A runny yolk adds an extra layer of richness when mixed into the noodles, but any style will work.
Boil the somyeon noodles according to the package instructions (usually just 3–4 minutes). Drain and rinse under cold water to stop the cooking and keep the noodles bouncy.
In a small bowl, combine the soy sauce, perilla oil, and sugar. Stir until the sugar dissolves completely.
Place the noodles in a bowl. Top with the sautéed zucchini, fried egg, chopped lettuce, crushed seaweed, and a generous sprinkle of sesame seeds.
Drizzle the sauce over everything, mix thoroughly, and enjoy immediately!
