Light, gluten-free soba tossed in a sesame-soy dressing with scallions and toasted sesame.

This is my go-to gluten-free soba salad when I want something fast, bright, and satisfying. Using 100% buckwheat soba keeps it genuinely gluten-free, and a simple sesame-soy dressing (made with gluten-free tamari) brings nutty, tangy flavor that clings to every strand. It’s the kind of dish I make when the weather’s warm or when I need a light dinner that feels a little special.

The recipe is easy to customize: toss in cubed tofu or leftover roast chicken for protein, add crunchy cucumbers and carrots for texture, and finish with a scatter of toasted sesame and nori for that quintessential Japanese touch. Ready from start to finish in about 25 minutes, it’s perfect for weekday lunches or a casual weeknight meal.

Directions

  1. 1
    Soba noodles being rinsed in a colander after boiling

    Bring a large pot of salted water to a boil and cook the gluten-free soba according to the package directions until just tender (usually 4–5 minutes). Drain, rinse under cold water to stop cooking, and set aside.

  2. 2
    Sesame soy dressing whisked with ginger and garlic

    While the noodles cook, whisk together sesame oil, tamari, rice vinegar, maple syrup, grated ginger, and minced garlic in a small bowl until smooth. Taste and adjust—more vinegar for brightness, more maple for sweetness.

  3. 3
    Tofu cubes browning in a nonstick skillet

    If using tofu, heat 1 tsp sesame oil in a nonstick skillet over medium and lightly brown the cubed tofu on all sides, 4–6 minutes. Set aside.

  4. 4
    Sesame soy dressing poured over soba noodles and vegetables

    In a large bowl, combine the cooled soba, sliced scallions, cucumber ribbons, julienned carrot, and toasted sesame seeds. Pour the dressing over and toss gently to coat evenly.

  5. 5
    Finished soba noodle salad topped with tofu and nori

    Fold in the browned tofu if using, sprinkle with torn nori and a pinch of crushed red pepper if you like heat, and serve chilled or at room temperature.

Ingredients

  • 100% buckwheat soba noodles (gluten-free):8 oz
  • Sesame oil:2 tbsp
  • Tamari (gluten-free soy sauce):3 tbsp
  • Rice vinegar:2 tbsp
  • Maple syrup:1 tbsp
  • Fresh ginger, grated:1 tsp
  • Garlic, minced:1 clove
  • Scallions, thinly sliced:3 pieces
  • English cucumber, thin ribbons:1/2 cup

Tips & Notes

  • Buy 100% buckwheat soba to ensure the noodles are truly gluten-free—many soba blends include wheat.
  • Rinse the cooked noodles under cold water thoroughly to remove starch and keep the texture springy.
  • Toast sesame seeds in a dry pan over medium heat for 1–2 minutes until fragrant to boost flavor.
  • Make the dressing ahead—flavors meld nicely and it keeps in the fridge for up to 5 days.
