1. Preparation
Gather all ingredients and tools needed: pot, saucepan, whisk, and serving bowls.
Slice the green onions thinly, separating the white parts from the green tops.
Chop the mushrooms and carrot into thin slices.
Measure out the sesame oil, soy sauce, and miso paste.
Prepare the ramen noodles according to package instructions, usually 3-5 minutes of boiling.
2. Cooking Broth
In a medium saucepan, heat 1 tablespoon of sesame oil over medium heat.
Add the sliced white parts of the green onions and sauté for about 2 minutes until fragrant.
Stir in the chopped mushrooms and carrot, cooking for another 3-4 minutes until softened.
Add 4 cups of vegetable broth to the saucepan and bring to a gentle simmer.
In a small bowl, mix 1 tablespoon of miso paste with a ladle of the hot broth to dissolve it, then add it back to the saucepan.
Stir in 2 tablespoons of soy sauce and let the broth simmer for about 5 minutes.
3. Combine and Serve
Once the ramen noodles are cooked, drain and divide them into serving bowls.
Ladle the hot broth with vegetables over the noodles in each bowl.
Garnish with sliced green tops of the onions and sprinkle toasted sesame seeds on top.
For extra flavor, drizzle a bit more sesame oil over each bowl before serving.
