How to Make Japanese Udon Noodle Soup

1
Start by preparing the ingredients. Slice the onions and ginger, and mince the garlic. Cut the green onions into thin slices and set aside.
2
In a large heavy pot or Dutch oven, heat 2 tablespoons of sesame oil over medium heat. Add the sliced onions and cook, stirring occasionally, until they're softened and lightly browned, about 8-10 minutes.
3
Add the minced garlic and sliced ginger to the pot and cook, stirring constantly, for 1-2 minutes. Be careful not to burn the garlic or ginger.
4
Add the chicken or pork bones to the pot and cook, stirring occasionally, until they're lightly browned, about 5-7 minutes.
5
Add the water, soy sauce, sugar, and salt to the pot. Bring the mixture to a boil, then reduce the heat to low and simmer, covered, for 1-2 hours, or until the broth is rich and flavorful.
6
While the broth is simmering, cook the udon noodles according to the package instructions. Typically, this involves boiling them in water for 8-10 minutes, or until they're slightly firmer than you like them. Drain the noodles and set them aside.
7
Once the broth is ready, strain it through a colander or strainer into a clean pot. Discard the solids and return the broth to the pot.
8
Add the cooked noodles to the broth and cook, stirring occasionally, until they're heated through, about 2-3 minutes.
9
Taste and adjust the seasoning as needed. You can add more soy sauce, sugar, or salt to taste.
10
Serve the Udon Noodle Soup hot, garnished with sliced green onions and your choice of toppings, such as sliced pork, boiled eggs, or pickled ginger.
11
Let the soup rest for 10-15 minutes before serving to allow the flavors to meld together. You can also refrigerate or freeze the soup for later use.
