Sauté the aromatics: Heat oil in a large pot over medium. Add garlic and ginger.
Cook 30–60 seconds until fragrant. Stir in gochujang and miso, letting them toast lightly so they melt into the oil.
Build the broth: Pour in chicken broth. Add soy sauce, rice vinegar, sesame oil, and sugar or honey.
Bring to a gentle boil, then reduce to a simmer for 10 minutes to let flavors round out.
Cook the mushrooms: Add sliced mushrooms to the simmering broth. Let them soften for 4–5 minutes. Taste and adjust seasoning with more soy sauce, vinegar, or a pinch of salt.
Warm the chicken: Stir in shredded chicken and let it heat through for 2–3 minutes.
If the broth tastes flat, add a splash more soy or a squeeze of lime.
Boil the eggs (optional): In a separate pot, boil eggs for 6½–7 minutes for jammy yolks. Transfer to an ice bath, peel, and halve.
Cook the noodles: In the same pot used for eggs or a clean one, cook ramen according to package directions until just tender. Drain and rinse briefly to stop cooking.
Add greens: Stir spinach or bok choy into the hot broth until just wilted, about 1 minute.
Assemble: Divide noodles among bowls.
Ladle hot broth, chicken, and veggies over the top. Finish with scallions, sesame seeds, egg halves, and optional chili oil, nori, or herbs.
Serve: Enjoy immediately while piping hot. Add extra chili-garlic sauce at the table if you like it spicier.
