Vegetarian Udon Noodle Soup

 4 oz udon noodles
 1 tbsp canola oil
 1 ½ tbsp minced fresh garlic
 1 tbsp grated fresh ginger
 1 serrano pepper, seeded and minced
 1 (32 fluid ounce) container low-sodium vegetable broth
 1 tbsp mirin
 1 tbsp low-sodium soy sauce plus 1 teaspoon, divided
 2 cups sliced cremini mushrooms
 1 cup sliced cremini mushrooms
 1 cup diced carrots
 2 heads baby bok choy, cut into 1-inch pieces
 ½ cup warm water
 2 tsp white miso (see tip)
 1 14 (ounce) package extra-firm tofu, drained and cubed
 ½ cup thinly sliced scallions (4 medium)
 3 tsp toasted sesame oil, divided

Cook noodles according to package directions; drain and set aside.


Meanwhile, heat oil in a large pot over medium heat. Add garlic, ginger, and serrano; cook until fragrant, about 1 minute. Add broth, mirin, and 1 Tbsp. soy sauce; bring to a simmer. Stir in mushrooms and carrots; simmer until the carrots are just tender, 3 to 6 minutes. Stir in bok choy and cook until the vegetables are tender, about 2 minutes more.


Whisk warm water and miso in a small bowl until smooth; add to the pot. Stir in tofu and cook until heated through, about 1 minute.


Stir scallions into the soup. Divide the noodles among 4 bowls. Ladle the soup over the noodles. Drizzle each bowl with 1 tsp. toasted sesame oil and 1/4 tsp. of the remaining soy sauce.


Miso is a fermented soybean paste that contributes a deep, rich umami flavor. White miso is a sweet variety made with soy and rice. Look for it in the refrigerated section of well-stocked supermarkets, near the tofu. It will keep in the refrigerator for at least a year.
