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.

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
  • Carrot, julienned:1 cup
  • Toasted sesame seeds:1 tbsp
  • Crushed red pepper (optional):1/4 tsp
  • Nori sheet, torn into strips (optional):1 sheet
  • Firm tofu, cubed (optional):8 oz

Instructions

  1. 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. 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. 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. 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.

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.
