In a large pot, combine the chicken or vegetable broth, water, soy sauce, miso paste, sake (if using), mirin, minced garlic, and minced ginger.
Bring to a simmer over medium heat and cook for about 10-15 minutes to allow the flavors to meld.
In a separate pot, cook the ramen noodles according to the package instructions until al dente.
Drain the noodles and set aside.
Divide the cooked noodles among serving bowls.
Pour the hot broth over the noodles, distributing it evenly.
Top each bowl with halved soft-boiled eggs, sliced cooked chicken or pork, baby spinach or bok choy, corn kernels, and sliced green onions.
If using, add nori strips and sprinkle with toasted sesame seeds.
Enjoy your meal!
