About the Recipe

Soba noodles are a thin Japanese noodle made from buckwheat flour, though they sometimes have whole wheat added to them. They have a nutty flavor and soft texture when cooked. They cook very quickly and can be served chilled, hot or in soups.

This noodle salad is amazing for a light meal or simple side dish that can be enjoyed hot or cold. It’s made with soba noodles, which are nutritious, easy to cook and have a delicious soft texture that’s perfect for absorbing the lightly sweet and nutty sesame garlic sauce.

This recipe can be kept simple, made with just 8 ingredients, or work as a versatile base for additions like tofu, stir fried or fresh veggies.

For a variation on this recipe, you can try this Vegan Cold Buckwheat Noodles with Miso Sauce. The sauce is more miso-based than sesame and it has edamame, carrot and bean sprouts.

This Vietnamese Rice Noodle Salad with Tangy Dressing and Cold Asian Noodle Salad with Peanut Dressing are really good for a cold salad as well.

This list is not complete. Please see the recipe card at the end of the post for the complete ingredient list with measurements and detailed instructions.

  • Soba Noodles: Soba noodles (soba buckwheat noodles/buckwheat noodles) vary from brand to brand, so you may have to experiment a little until you find the one you like. I love the Hakubaku brand soba noodles but there are plenty of other good ones. They’re available in Asian markets, online or in well-stocked grocery stores.
  • Sesame Oil: This is what makes these “sesame soba noodles” so don’t substitute it for a different oil. Toasted sesame oil is best for flavouring the sauce but if you can’t find it, you can use regular sesame oil.
  • Tamari or Soy Sauce: For gluten-free, use tamari, other wise regular or low-sodium soy sauce works. You could also use coconut aminos for a soy-free recipe.
  • Maple Syrup: Lightly sweetens and balances the sauce. Agave syrup would also work here.
  • Miso Paste: Use white or yellow miso paste. Dark miso paste is also ok if that’s all you have, it will just have a slightly stronger flavour.
  • Rice Vinegar: You can use seasoned or unseasoned rice vinegar.
  • Garlic: Fresh garlic is best here.
  • Green Onions: Also called scallions or spring onions. You’ll need about one standard-sized bunch you’d get at the store.
  • Toppings: Optional toppings include sesame seeds and thinly sliced nori.


There are so many different ways you can go with this dish. From a light and simple cold salad to a stir fry with tofu, there are so many options for customizing!

  1. Cold Salad with Veggies: For a cold salad with more fresh veggies, try grated carrot, shredded cabbage and thinly sliced bell pepper. Simply mix everything up in a large bowl or serve with the fresh veggies on top.
  2. Soba Noodle Stir Fry: To add stir fried vegetables to this recipe, follow the stir fry portion of this teriyaki chickpea recipe, then add the noodles and sauce once the veggies are ready.
  3. For Spicy Soba Noodles: Add 1 tsp red chili flakes, chili garlic pasta, chili pasta or sriracha to the sauce.
  4. For Creamy Sesame Noodles: Add 1-2 tbsp tahini or peanut butter to the sauce.
  5. Adding Protein: Mix in edamame or another protein of choice or serve with this baked tofu or pan-fried tofu on top.
  6. Alternative Sauces: You could also mix the cooked soba noodles with this spicy miso sauce, peanut sauce or teriyaki sauce.

Step-by-Step Instructions

Step 1: Mix up the sesame sauce.

Sesame miso garlic sauce mixed together in a small bowl. A spoon rests in the bowl.

Start bring a large pot of water to a boil on the stovetop. While you’re waiting, mix up the sesame garlic sauce in any bowl or container until smooth and fully combined.

It may take a minute or two to fully incorporate the oil into the other ingredients, so just keep whisking until it does! Before you mix it with the noodles, give it another quick stir.

Quick Tip: Make sure you measure the sauce ingredients accurately for the perfect balance of flavours.

Step 2: Cook the soba noodles.

Once the pot of water is fully boiling, add the noodles and cook for 3-4 minutes or according to the package instructions.

Once they’re cooked, drain and rinse well under cold water to remove excess starch and prevent clumping.

Soba Noodle Cooking Tips

  1. Cook soba noodles in unsalted water (unlike regular pasta).
  2. Use a large pot. Soba noodles need room to cook so don’t crowd the pot. Give them a stir once you add them to the boiling water.
  3. Soba noodles cook very quickly in just 3-5 minutes, so watch closely and be careful not to overcook them. They should be cooked al dente.
  4. Rinse in cold water. Rinse the cooked noodles well under cold water to stop the cooking process and remove excess starch, which prevents them from sticking. Toss them around to ensure all the noodles get rinsed off.

Step 3: Stir fry the green onions.

Thinly sliced stir fried green onions cooking in a pan.

When the noodles and sauce are ready, heat 2 tsp oil in large skillet or wok over medium-high heat. Add the green onions and stir fry for 1-2 minutes.

Quick Tip: If you’re adding other veggies such as carrot, cabbage, bell pepper or bok choy, add those now as well.

Step 4: Mix everything.

  • For cold soba noodles: Add the cold noodles, sauce and stir fried green onions to a mixing bowl and toss to coat. You can also just mix in the pan then chill in the fridge if you won’t be serving right away.
  • For hot noodles: Add the noodles and sauce to the green onions in the pan, toss to coat and cook 1-2 minutes to heat through.

The noodles are delicious served right away but are actually even better after sitting so the flavours really have time to meld together!

Serve your noodles hot, at room temperature or chilled topped with toasted sesame seeds, nori and the remaining green onions.

Quick Tip: For the most flavourful, nutty sesame seeds for garnish, purchase toasted sesame seeds or toast your own for 2-3 minutes in a pan on the stovetop over medium heat until lightly browned.
