Ingredients

  • 4 large shiitake mushrooms, stemmed
  • Vegetable oil cooking spray
  • Salt and freshly ground pepper
  • 2 teaspoons sugar
  • 3 tablespoons low-sodium soy sauce
  • 2 tablespoons mirin (see Note)
  • 10 ounces soba noodles (see Note)
  • 5 cups boiling water
  • 2 teaspoons instant dashi or 1 tablespoon miso paste (see Note)
  • 4 ounces firm tofu, cut into 1/2-inch dice
  • 2 cups baby spinach leaves
  • 1/4 cup finely shredded daikon
  • 1 scallion, thinly sliced
  • 1 sheet nori seaweed, cut into 1/8-inch strips (see Note)

Method

  • Preheat the broiler.
  • Spray the mushroom caps with vegetable oil cooking spray, season with salt and pepper and broil 6 inches from the heat, turning the caps once, until lightly browned and tender, about 6 minutes.
  • Let cool, then thinly slice the mushrooms.
  • In a small bowl, stir the sugar into the soy sauce and mirin until dissolved.
  • In a large saucepan of boiling water, cook the soba noodles, stirring once or twice, until just tender, about 8 minutes.
  • Drain the noodles, rinse under cold water and drain again thoroughly.
  • Add the boiling water and instant dashi to the saucepan.
  • Add the tofu and shiitake and simmer just until heated through, about 2 minutes.
  • Add the spinach.
  • Transfer the soba to 4 deep bowls and spoon the dashi mixture on top.
  • Garnish the soba with the daikon, scallion and nori and serve right away, passing the soy sauce mixture alongside.
