How To Make Soba Noodle Soup

While this may not be an authentic Japanese recipe for Toshikoshi Soba – that’s why I call it simple and easy – the taste of it comes pretty darn close. The hot broth infused with ginger, garlic, and soy sauce is reason enough to bring this noodle soup to a dinner table near you!

  1. Sauté Mushrooms: Warm up the olive oil in a stockpot and cook the mushrooms until tender.
  2. Add Aromatics: Stir in the garlic and ginger to infuse their flavors into the mushrooms.
  3. Pour in Soy Sauce & Broth: Mix in the soy sauce and vegetable broth and bring them to a boil.
  4. Noodles and Greens: Toss in the soba noodles and Swiss chard; cook just until the noodles are perfect and the greens wilted.
  5. Garnish and Serve: Ladle the soup into bowls and top with the garnishes – carrots, scallions, eggs, and a dash of sesame seeds.

Tips And Variations

  • Noodle Watch: Be cautious with the cooking time for soba noodles; overcooking can make them mushy. Follow the package instructions or taste test to get that perfect, slightly chewy texture.
  • Experiment with Proteins: While the recipe is vegetarian, feel free to add cooked chicken, tofu, or even shrimp if you desire extra protein.
  • Spice Lovers Alert: If you like a bit of heat, sprinkle some red pepper flakes or drizzle a bit of chili oil on top before serving.
  • Seasonal Veggies: The recipe is versatile. Adapt it according to the season, using fresh, in-season vegetables to maximize flavor and nutrition.
  • Storage: Store leftovers in an airtight container. Soba soup will last for 4 days in the fridge.

Servings : 4 Serves
Prep Time 10 minutes
Cook Time 20 minutes
Total Time 30 minutes


  • 2 tablespoons olive oil
  • 8 ounces button mushrooms, sliced
  • 3 cloves garlic, minced
  • ½ tablespoon minced fresh ginger
  • ¼ cup low sodium soy sauce
  • 6 cups low sodium vegetable broth
  • 4 to 6 ounces soba noodles, you can also use whole wheat spaghetti
  • 1 bunch (about 8 leaves) swiss chard, trimmed and washed, you can also use a head of bok choy
  • 2 small carrots, shredded, for garnish
  • 4 scallions, thinly sliced, for garnish
  • 4 hard-boiled eggs, halved
  • 1 tablespoon toasted sesame seeds, for garnish


  • Heat olive oil in a stock pot over medium heat. Add the sliced mushrooms and cook for 4 minutes. Stir in the garlic and ginger; continue to cook for 30 seconds or until fragrant.
  • Stir in the soy sauce and cook for 3 minutes or until the mushrooms are soft. Stir in the vegetable broth and bring to a boil. Add the noodles and greens and cook until the noodles are tender, about 5 to 6 minutes.
  • Remove from heat and ladle the soup into bowls.
  • Garnish with shredded carrots, scallions, hard boiled eggs, and toasted sesame seeds.
  • Serve.


  • Make Ahead: Make the broth in advance and keep the noodles separate until you’re ready to serve to keep them from going soft.
  • Avoid Overcooking: Keep a close eye on those soba noodles; you want them tender but not mushy. A taste test can help nail that perfect texture.
  • Add Some Meat: If you’re not sticking to a vegetarian vibe, toss in some cooked chicken, tofu, or shrimp to ramp up the protein.
  • Heat Things Up: For those who love a kick, a sprinkle of red pepper flakes or a dash of chili oil can turn up the heat.
  • Perfect Pairings: Although the soup’s a star on its own, try it with steamed dumplings or a crisp salad for an extra special meal.
