Ingredients
  

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

Instructions
 

  • 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.

Notes

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.
