At its base, this cold salad is a simple 10-minute meal or side dish. But the hidden beauty of this recipe is that you can add so much to it to suit your needs. Use up whatever veggies you have in your crisper drawer.

Don’t have soba noodles in the pantry? Use spaghetti, udon, angel hair, ramen noodles, or whatever is already in your cupboard. This is the ultimate “use what you have” kind of recipe, and that’s a beautiful (and delicious) thing.

Add some protein and this becomes a full meal. It’s also incredible served with a side of Air Fryer Egg Rolls or Air Fryer Potstickers and your favorite dipping sauce.

What’s In This Cold Soba Noodle Salad?

  • Noodles! Soba/buckwheat is delicious, but use what you have!
  • Veggies – celery and green onions, but use whatever you want
  • Delicious sauce goodness – soy sauce, rice vinegar, and sesame oil
  • Extras – sesame seeds, and hot sauce or wasabi (if you dare. I do!)

Add some delicious roasted veggies to the finished noodles. Related: Roasted Frozen Broccoli and How to Roast Frozen Vegetables. Other fresh veggies that will rock: sliced cucumber, green beans, snap peas, shredded cabbage, bok choy, carrots, sliced peppers. And maybe a sprinkling of fresh cilantro.

Want to make this a complete meal? Add your favorite protein like Air Fryer Tofu, shredded chicken, Spicy Pork Meatballs, shrimp, or a big topping of chopped peanuts. To up the extraness of the sauce, add a splash of fresh lime juice, 2 tbsp of peanut butter, some grated ginger (related: How to Freeze Ginger), chopped garlic (related: How to Freeze Garlic).

Pro Tips/Recipe Notes

  • Since this dish is served cold, consider meal prepping it up to 2-3 days ahead. You can add the sauce before storing it in the fridge, or add to individual portions when serving.
  • The noodles can dry out after a few days in the fridge, even in an air-tight container. A splash of rice vinegar perks them right back up!

  1. The Cold Soba Noodle Salad is a great easy, fast and flavorful dish! We served this alongside a fish stir fry that was a bit spicy and the Cold Soba Noodle Salad was a nice compliment.
    What a fabulous recipe! Will make this many times again!5 stars

    1. Ohhhh I love the idea of serving it WITH something spicy. I usually cover mine with chili sauce, but using it as a compliment would be great too! 🙂

  2. I was intrigued by this recipe. I’ve never cooked with Soba noodles but with the promise of a quick and tasty meal, I decided to give it a shot. It was super easy to throw together and was very flavorful even with so few ingredients. This recipe will be added into the weeknight rotation. Thanks!5 stars

  3. Tried this last night – it is super easy! I added more veggies – some carrots, cabbage, and red bell peppers. Packed some for my lunch today, I like it cold.5 stars

  4. Love that you call it “hot cock”! That’s what we call sriracha! This looks yummy and super easy, I’ll have to try it. Thx! -Heather

  5. Love this recipe! I will be trying it soon. thank you so much for sharing. And quick recipes that also taste great and are a little different are a huge plus for me. Thank you!

  6. YUM! YUM!! It’s always nice to have a Go To tried and true standby! I’m going to share this with Amber – it’s right up her alley!5 stars

  7. Yum! I wonder if you could serve it hot too? I love hot foods but a nice cold salad is always good in the summer months 🙂5 stars

  8. Our favorite sushi restaurant serves a small portion of a variation of this as an amuse-bouche. The only difference is they replace the chili sauce for wasabi. Thanks for the recipe!5 stars
