Begin by heating the sesame oil in a large pot over medium heat. Once hot, add the minced garlic and grated ginger. Sauté them for about 1 minute until they become aromatic, ensuring not to burn them.
Introduce the sliced shiitake mushrooms to the pot. Cook for approximately 3-4 minutes, stirring occasionally, until the mushrooms have softened and released their moisture.
Carefully pour in the chicken or vegetable broth, followed by the soy sauce and miso paste. Stir well to combine, ensuring that the miso paste is fully dissolved. Allow the mixture to come to a gentle simmer.
Once the broth is simmering, add the ramen noodles. Cook them according to the package instructions, which should take about 3-4 minutes.
In the final minute of cooking, incorporate the baby spinach and sliced green onions into the pot. Stir gently until the spinach wilts down.
Meanwhile, prepare the soft-boiled eggs. In a separate small pot, bring water to a rolling boil. Gently place the eggs into the boiling water and let them cook for 6-7 minutes. Once done, transfer the eggs to an ice bath immediately to halt the cooking process before peeling them under cool running water.
Taste the broth at this point, adjusting seasoning if needed. Once every ingredient is cooked through, turn off the heat.
To serve, ladle the steaming ramen into large bowls. Slice the soft-boiled eggs in half and place them atop the noodles. Garnish generously with nori strips, extra green onions, and a sprinkle of sesame seeds for added texture and visual appeal.
Notes
Serve in large bowls with chopsticks and soy sauce for dipping.
