Steps
Before you start
- Pat the cod fillets dry with paper towels so they cook evenly
- Have all ingredients prepped and measured before you start cooking
- Use fresh ginger for the best flavor—pre-sliced or jarred will taste flat
Build the base broth
- Pour the chicken broth into a 6-quart pot and bring to a gentle simmer over medium-high heat, about 5 minutes.
- Once steaming, reduce heat to medium.
- Add the minced ginger and garlic, stirring well.
- Simmer for 1 minute, allowing the aromatics to infuse the broth.

Ready when: Broth is steaming gently with aromatics fragrant
Tip: Don't let the ginger and garlic brown—they should smell sweet and fresh, not scorched
Season the broth
- Stir in the soy sauce, sesame oil, and rice vinegar.
- Taste the broth and adjust seasoning as needed—it should be savory and slightly tangy.
- If you like heat, add red pepper flakes to taste now.

Ready when: Broth is fragrant and well-seasoned
Tip: Taste as you go—you can always add more soy or vinegar, but you can't remove it
Add the cod
- Gently lower the cod pieces into the simmering broth.
- The broth should cover the fish by at least an inch.
- Maintain a gentle simmer over medium heat (not a rolling boil, which will break the fish apart).
- Cook uncovered for 4–5 minutes until the cod is just barely opaque throughout and flakes easily with a fork.

Ready when: Cod is opaque and flakes apart with a fork, internal temperature 145°F (63°C)
Tip: Add the fish gently so it doesn't break. A gentle simmer is crucial—aggressive boiling will shred delicate cod
Cook the noodles
- Add the ramen noodles directly to the broth, breaking them apart with your spoon as they soften.
- Stir gently to separate the noodles and prevent sticking.
- Cook for 3–4 minutes, stirring occasionally, until the noodles are just tender but still have a slight bite.

Ready when: Noodles are soft but still have slight firmness when bitten
Tip: Ramen noodles cook quickly—don't walk away. Overcooked noodles will become mushy and absorb too much liquid
Add the bok choy
- Stir in the bok choy pieces, pressing them gently into the broth.
- Continue simmering over medium heat for 2–3 minutes until the bok choy is wilted and tender-crisp, with stems still having a slight firmness.

Ready when: Bok choy is wilted, bright green, with stems tender but not soft
Tip: Don't overcook the bok choy—it will turn dark and lose its tender texture and flavor
Finish and serve
- Carefully ladle the soup into four bowls, distributing the cod, noodles, and bok choy evenly.
- Top with the white and light green parts of scallions (if using), and a light sprinkle of red pepper flakes if desired.
- Serve immediately while the broth is piping hot.

Ready when: Soup is distributed evenly and garnished
Tip: Add the dark green scallion tops at the very end so they stay bright and fresh-tasting rather than wilting in the hot broth
Good to know
Tips
- Pat the cod dry before adding to the pot—excess moisture prevents a clean, delicate cook and can cloud the broth
- Maintain a gentle simmer throughout; a rolling boil will break apart the delicate fish and make the broth cloudy
- For extra depth, use a combination of soy sauce and tamari (wheat-free soy sauce) or add a splash of mirin for subtle sweetness
- Prep all ingredients before you start cooking—this is a quick dish, and there's no time to chop mid-recipe
Storage & reheating
Leftover soup keeps in an airtight container in the refrigerator for up to 1 day. The noodles will continue to absorb broth and soften, so it's best enjoyed fresh. To reheat, gently warm in a pot over medium heat until steaming, but do not boil—prolonged heat will make the cod tough. Do not freeze, as the delicate cod texture and noodle consistency will degrade.
Substitutions
- cod fillets → halibut, haddock, or sea bass fillets (1.25 lb/560 g, same prep and cooking time). Any mild, flaky white fish works here. Avoid very oily fish like salmon, which will overwhelm the delicate broth
- dried ramen noodles (discard seasoning packet) → dried egg noodles, soba noodles, or lo mein (6 oz/170 g, cooked to package directions). Adjust cooking time slightly based on the noodle type—check package directions for texture preference
- bok choy → fresh spinach (5 oz/140 g), baby kale, or gai lan (Chinese broccoli), chopped. Delicate greens like spinach cook faster (30–60 seconds); heartier greens like kale take 2–3 minutes
- low-sodium chicken broth → vegetable broth or dashi (kombu and bonito flake stock) for a lighter or more umami-forward version. Dashi deepens the Asian flavor profile; vegetable broth keeps the soup light and lets the fish shine
