Ingredients

  • 200g dried or fresh udon noodles
  • 6 cups vegetable broth (preferably low sodium)
  • 1 cup shiitake mushrooms, sliced
  • 1 small carrot, julienned
  • 1 cup baby spinach or bok choy leaves
  • 1/2 cup firm tofu, cubed
  • 3 tablespoons soy sauce or tamari for gluten-free
  • 1 tablespoon miso paste (white or yellow)
  • 2 cloves garlic, minced
  • 1 teaspoon ginger, freshly grated
  • 1 tablespoon sesame oil
  • 2 green onions, sliced thinly
  • 1 teaspoon toasted sesame seeds, for garnish
  • Optional: chili flakes or sriracha for heat

Equipment

  • Large pot or Dutch oven
  • Medium saucepan (for noodles)
  • Sharp knife
  • Cutting board
  • Wooden spoon or ladle
  • Measuring cups and spoons
  • Colander or strainer
  • Serving bowls

Instructions

  1. Prepare the broth: In a large pot, heat the sesame oil over medium heat. Add the minced garlic and grated ginger, sautéing for about 1 minute until fragrant but not browned.
  2. Add shiitake mushrooms: Toss in the sliced mushrooms and cook for 3-4 minutes, allowing them to soften and release their umami flavor.
  3. Pour in vegetable broth: Add the 6 cups of vegetable broth and bring to a gentle boil.
  4. Mix in soy sauce and miso paste: Lower the heat to a simmer. In a small bowl, dissolve the miso paste with a few tablespoons of hot broth, then stir it back into the pot along with the soy sauce.
  5. Cook the udon noodles: Meanwhile, cook the udon noodles separately in boiling water according to package instructions (usually 8-10 minutes for dried). Drain and set aside.
  6. Add tofu and vegetables: Add the cubed tofu, julienned carrots, and baby spinach or bok choy to the broth. Let simmer for 2-3 minutes until the greens wilt slightly.
  7. Assemble the soup: Divide the cooked noodles into serving bowls. Ladle the hot broth with vegetables and tofu over the noodles.
  8. Garnish and serve: Top each bowl with sliced green onions and a sprinkle of toasted sesame seeds. Add chili flakes or sriracha if you like a bit of heat.

Tips & Variations

“For a deeper flavor, try adding a piece of kombu (dried kelp) to the broth while simmering, removing it before serving.”

  • Make it heartier: Add other vegetables like snap peas, corn, or baby corn for extra crunch.
  • Protein boost: Swap tofu for tempeh or add cooked edamame beans.
  • Gluten-free: Use gluten-free tamari and substitute udon noodles with rice noodles or shirataki noodles.
  • Spice it up: Incorporate fresh sliced chili, a dash of chili oil, or drizzle sriracha on top.
  • Herbs: Fresh cilantro or Thai basil make wonderful aromatic garnishes.
