Korean Udon Noodle Soup is a comforting dish that’s perfect for chilly days or when you need a bowl of something warm and satisfying. The thick, chewy udon noodles swim in a rich broth that’s full of flavor, thanks to a mix of traditional Korean seasonings. Korean Udon Noodle Soup isn’t just about the noodles though; it’s the combination of savory ingredients like soy sauce, garlic, and a touch of sesame oil that bring everything together. Whether you’ve had it before or are trying it for the first time, this dish will warm you right up.
A Flavorful Broth
To start making Korean Udon Noodle Soup, the key is the broth. You’ll want to get the base just right, which involves simmering ingredients like soy sauce, garlic, and gochujang (Korean chili paste) for that deep umami flavor. Korean Udon Noodle Soup’s broth has a balance of salty, spicy, and savory notes that make each spoonful irresistible. Add some ginger for extra warmth and complexity, and you’ll have a broth that is both comforting and energizing. It’s the heart of this soup, so take your time with it.
Preparing the Noodles
Once your broth is ready, it’s time to bring in the udon noodles. Korean Udon Noodle Soup uses these thick, soft noodles that soak up all the delicious flavors of the broth. You can find fresh or frozen udon at most grocery stores, making them easy to incorporate into this dish. Boil the noodles separately, and then add them into your flavorful broth just before serving. The noodles are the perfect base, giving the soup its satisfying texture. You’ll be hooked from the first bite.

Toppings and Final Touches
No Korean Udon Noodle Soup is complete without a few toppings to finish it off. Try adding a boiled egg, green onions, and a sprinkle of sesame seeds for a bit of crunch. For extra flavor, drizzle in some sesame oil or add a spoonful of kimchi on the side. Korean Udon Noodle Soup is a customizable dish, and the toppings are your chance to make it your own. The combination of soft noodles, rich broth, and fresh toppings creates a bowl that’s both hearty and full of flavor, perfect for any day of the week.

Chef’s Notes- Korean Udon Noodle Soup
- Chicken Poaching Tips: Poach the chicken thighs gently over medium-low heat to ensure they stay tender and juicy. Use an instant-read thermometer to check the internal temperature (175°F) to avoid overcooking.
- Adjust Spice Level: Customize the heat level by adjusting the amount of gochujang (Korean red chili paste) and gochugaru (Korean red pepper flakes). Start with less and add more to taste.
- Broth Consistency: If you prefer a richer broth, you can add a small splash of soy sauce or a teaspoon of sesame oil after the broth simmers for an added depth of flavor.
- Noodles Cooking Tip: Make sure to cook the udon noodles al dente to prevent them from becoming mushy when added to the broth. It’s important to drain them well before adding to the soup.
- Make Ahead Tip: The broth can be made in advance and stored in the refrigerator for up to 2 days. Just heat it up when you’re ready to assemble the soup.
- Vegan/Vegetarian Variation: For a plant-based version, replace chicken with tofu, vegetable broth, and omit the eggs. Add extra vegetables like mushrooms, spinach, or bok choy for added texture and nutrients.
- Shredding Chicken: After poaching the chicken, let it cool slightly to avoid burning your fingers when shredding. Use two forks to easily shred the chicken into bite-sized pieces.
