Odeng Fishcake Soup (오뎅탕) With Collagen

Eomuk Tang | Korean Street-Style Collagen Soup

Steamy skewers, golden broth, and that ocean-fresh aroma — Odeng Tang (Eomuk Tang) is the cozy Korean street-food soup we crave all winter. This version builds a quick, ultra-clear base with Crushed Tonic Korean Fish Stock, then finishes with hydrolyzed collagen for skin, joint, and gut support — a warm comfort made functional.

Time: 15 minutes
Serves: 2–3 bowls
Collagen: ~5–10 g per bowl (depending on add-in)

ingredients

Broth

  • 4 cups water

  • 1 tbsp Crushed Tonic Korean Fish Stock (collagen broth base)

  • 2–3 thin slices Korean radish (mu) (optional but classic)

  • 2 dried kelp (dashima) pieces, 2×2 in (optional; remove before boil)

  • 1–2 tsp soy sauce or guk ganjang, to taste

  • Sea salt, to taste

  • A few drops toasted sesame oil, to finish

Fishcakes & garnish

  • 6–8 Korean fishcakes (eomuk/odeng), cut or folded and skewered

  • 1 scallion, thinly sliced (whites + greens separated)

  • 1 small chili (cheongyang or serrano), thinly sliced (optional)

  • ½ sheet roasted seaweed (gim), cut into thin strips (optional)

  • Black pepper, to taste

Collagen finish (choose one)

Optional dipping sauce:
Mix to taste: 1 tbsp soy sauce, 1 tsp rice vinegar, pinch sugar, pinch gochugaru, and sliced scallion greens

directions

  1. Build the base (5 min)
    In a pot, add water, Korean Fish Stock, radish, and kelp. Heat just below a boil, then remove kelp. Season with soy sauce and a pinch of salt. Add scallion whites and simmer.

  2. Simmer the fishcakes (5–6 min)
    Add skewered fishcakes to the broth. Gently simmer until heated through and flavors meld. Adjust salt/soy to taste.

  3. Collagen finish (1 min)
    Lower heat. Whisk collagen with a ladle of hot broth until smooth, then stir back in. (Collagen peptides are heat-stable at typical cooking temperatures — adding at the end keeps flavor pristine.)

  4. Serve street-style
    Ladle hot broth into bowls, add skewers, and top with scallion greens, chili slices, gim, a few drops of sesame oil, and black pepper. Serve with the dipping sauce on the side for the full street-food experience.

why add collagen to odeng tang

  • Seamless: hydrolyzed peptides dissolve cleanly — no change in flavor or texture.

  • Daily dose: easy, cozy way to reach 5 g+ collagen through a meal you already love.

  • Light yet nourishing: Korean Fish Stock keeps the broth clear and digestible.

make it yours

  • Extra clear: season only with salt for a restaurant-style, pale broth.

  • Spicy cart vibes: stir in a spoonful of gochugaru or serve chili soy sauce on the side.

  • Veg boost: add enoki mushrooms, shiitake, or extra radish slices.

  • Gluten note: many fishcakes contain wheat — look for GF-labeled ones if needed.

faq

Does collagen change the taste?
No — it’s neutral and keeps the broth clean when whisked in properly.

Can I prep ahead?
Yes. Store skewers and broth separately. Reheat broth to a simmer, then add skewers for 2–3 minutes. Stir collagen in just before serving.

What if I don’t have kelp or radish?
No problem — Korean Fish Stock alone makes a full-bodied 15-minute broth.

Pairings?
Serve with tteokbokki, kimbap, or onigiri-style rice triangles for the ultimate street-food meal.
