Sauté the aromatics: Heat oil in a medium pot over medium. Add garlic, ginger, and the white parts of the green onions.
Cook 30–45 seconds until fragrant, not browned.
Build the broth: Pour in broth. Stir in soy sauce, mirin (or rice vinegar), and sesame oil. Bring to a strong simmer.
Add dumplings: Gently slide in the frozen dumplings.
Simmer 4–6 minutes, or per package, until they float and are heated through.
Cook noodles: Add ramen directly to the pot. Cook 2–3 minutes until just tender. If using fresh ramen, check sooner.
Add veggies: Stir in spinach or bok choy and mushrooms (if using).
Cook 30–60 seconds, just until wilted.
Season and finish: Taste the broth. Add more soy sauce for salt, a splash of vinegar for brightness, or chili oil for heat. Stir in the green onion tops.
Top and serve: Ladle into bowls.
Add soft-boiled egg halves, nori, sesame seeds, and a drizzle of chili crisp if you like. Serve hot.
