📝 About This Recipe

This vibrant Kimchi Noodle Soup is a masterclass in Korean comfort, balancing the deep umami of fermented cabbage with a clean, spicy broth. It features silky wheat noodles submerged in a complex liquid gold made from aged kimchi juice and a savory anchovy-kelp base. Perfect for chilly evenings or as a restorative remedy, this dish offers a symphony of textures—from the crunch of fresh bean sprouts to the tender bite of pork belly.

🥗 Ingredients

The Broth Base

  • 1.5 cups Aged Kimchi (well-fermented and chopped into bite-sized pieces)
  • 1/4 cup Kimchi Brine (strained from the kimchi jar)
  • 6 cups Anchovy Broth or Chicken Stock (homemade or high-quality store-bought)
  • 150 grams Pork Belly or Pork Shoulder (thinly sliced into small strips)
  • 1 tablespoon Toasted Sesame Oil

Seasonings

  • 1-2 tablespoons Gochugaru (Korean Chili Flakes) (adjust based on heat preference)
  • 3 cloves Garlic (minced)
  • 1 tablespoon Soy Sauce (use soup soy sauce if available)
  • 1/2 teaspoon Granulated Sugar (to balance the acidity of the kimchi)

Noodles & Vegetables

  • 200 grams Somen or Somyeon Noodles (thin wheat noodles)
  • 1/2 medium Onion (thinly sliced)
  • 3-4 pieces Shiitake Mushrooms (sliced)
  • 1/2 block Firm Tofu (cut into small cubes)
  • 1 handful Mung Bean Sprouts (washed and drained)

For Garnish

  • 2 stalks Green Onions (diagonally sliced)
  • 1 teaspoon Toasted Sesame Seeds
  • 1 sheet Nori (Roasted Seaweed) (shredded into thin strips)

👨‍🍳 Instructions

  1. 1

    In a large heavy-bottomed pot or Dutch oven, heat the toasted sesame oil over medium-high heat.

  2. 2

    Add the sliced pork belly and cook for 3-4 minutes until the fat begins to render and the edges turn slightly golden.

  3. 3

    Stir in the chopped kimchi and onions. Sauté for another 5 minutes until the kimchi becomes translucent and fragrant.

  4. 4

    Add the minced garlic, gochugaru, and sugar. Stir constantly for 1 minute to toast the spices without burning them.

  5. 5

    Pour in the anchovy broth (or chicken stock) and the kimchi brine. Bring the mixture to a vigorous boil.

  6. 6

    Once boiling, reduce the heat to medium-low. Add the shiitake mushrooms and simmer for 10-12 minutes to allow the flavors to meld.

  7. 7

    While the soup simmers, bring a separate pot of water to a boil. Cook the somyeon noodles according to package instructions (usually 2-3 minutes).

  8. 8

    Drain the noodles and rinse them thoroughly under cold running water to remove excess starch. This ensures a clean broth later. Drain well and set aside.

  9. 9

    Taste the simmering soup. Add the soy sauce and adjust salt if necessary. If the kimchi is very sour, you can add another pinch of sugar.

  10. 10

    Gently stir in the tofu cubes and bean sprouts. Let them cook in the broth for just 2 minutes until the sprouts are slightly wilted but still crunchy.

  11. 11

    Divide the cold noodles into individual serving bowls.

  12. 12

    Ladle the hot soup and plenty of solids (kimchi, pork, tofu) over the noodles. The hot broth will reheat the noodles instantly.

  13. 13

    Garnish generously with sliced green onions, toasted sesame seeds, and shredded nori before serving immediately.

💡 Chef's Tips

Use 'Old Kimchi' (Mukeunji) that has fermented for at least 2-3 weeks; the extra acidity is vital for a deep broth flavor. Do not cook the noodles directly in the soup, as the starch will make the broth thick and cloudy rather than clean and sharp. If you prefer a vegetarian version, substitute the pork with extra mushrooms and use a kelp-dried radish broth base. For an extra velvety texture, you can drop a raw egg into the boiling soup 1 minute before serving. Adjust the Gochugaru amount carefully; different brands vary significantly in heat levels.

🍽️ Serving Suggestions

Serve with a side of yellow pickled radish (Danmuji) to provide a sweet, crunchy contrast to the spicy soup. Pair with a cold glass of Barley Tea (Boricha) to soothe the palate between spicy bites. Add a side of crispy Korean vegetable pancakes (Pajeon) for a complete meal texture variety. A small bowl of steamed white rice on the side is perfect for soaking up any leftover broth at the end. For an alcoholic pairing, a chilled glass of Soju or a light Korean lager works beautifully.
