Prep the Noodles: Bring a large pot of water to a rolling boil. Add the udon noodles and cook according to the package instructions, typically 3-4 minutes for fresh noodles. Drain and rinse with cold water.

Create the Broth: In a medium saucepan, combine vegetable broth, miso paste, and coconut milk. Whisk together until miso is dissolved and smooth. Heat until simmering.

Simmer: Reduce heat and let the broth simmer for about 5 minutes, stirring occasionally to meld the flavors.

Add Sauces: Stir in soy sauce and sesame oil into the simmering broth, mixing well for enhanced flavor.

Combine: Add drained noodles to the broth, gently tossing to coat. Let them soak for 1-2 minutes to absorb flavor.

Serve: Ladle into bowls, topping with chopped green onions. Best enjoyed hot.
