Prepare the Broth:
In a large pot, heat sesame oil over medium heat. Add ginger and garlic, sautéing for 1–2 minutes until fragrant. Stir in the broth, water, soy sauce, and miso paste (if using). Bring to a gentle simmer.
Cook the Vegetables and Protein:
Add the mushrooms to the simmering broth and cook for 3–4 minutes until tender. Add your protein of choice (pre-cooked if necessary) and spinach or bok choy. Simmer for an additional 2 minutes.
Cook the Noodles:
In a separate saucepan, cook the ramen noodles according to package instructions. Drain and set aside.
Assemble the Bowls:
Divide the cooked noodles into serving bowls. Ladle the hot broth with vegetables and protein over the noodles.
Add Toppings:
Top each bowl with a soft-boiled egg, sliced green onions, and any optional toppings you like.
Serve and Enjoy:
Serve immediately while the soup is hot. Adjust the seasoning with more soy sauce or chili oil as desired.
