What are soba noodles?
Soba are Japanese noodles made from buckwheat flour. They are brown, long and slightly flattened with a mild, nutty flavour. They’re usually sold in portioned bundles. Be sure to check labels when buying if you need a gluten-free option; some brands mix buckwheat with wheat.

Are soba noodles gluten-free?
Buckwheat is not related to wheat and is naturally gluten-free. Traditional soba is made from 100% buckwheat flour, but many commercial varieties include wheat flour. If you need a gluten-free option, check that the packet states 100% buckwheat.
How are soba noodles served in Japan?
In Japan, soba are served hot in broths or cold with a dipping sauce. This recipe is a convenient, lunch-box-friendly version of cold soba. For children or packed lunches, I recommend mixing the dressing into the noodles rather than serving it as a dip to avoid spills.

Nutrition
Soba noodles offer good-quality plant protein and contain a favourable amino-acid profile compared with regular wheat pasta. They make an excellent protein choice for plant-based diets when you choose 100% buckwheat noodles.
Ingredients

- Soba noodles – choose 100% buckwheat if you require gluten-free noodles. Different brands vary in texture; try a few to find your favourite.
- Vegetables – broccoli florets, spring onions and a sprinkle of seaweed (furikake or torn nori) work well for flavour, texture and nutrients. Broccoli can be omitted if you prefer raw or other vegetables.
- Silken tofu – cubed silken tofu adds a silky texture and plant protein. If you prefer firmer or crispy tofu, use that instead.
- Sesame seeds – toasted add more flavour, but raw sesame seeds are fine for a quicker option.
- Dressing – tamari (or gluten-free soy sauce), rice vinegar, sesame oil, a sweetener such as brown rice syrup, and fresh grated ginger.

Cooking Tips
- Use a large pot with plenty of boiling water so the noodles can move freely and cook evenly.
- Rinse cooked soba thoroughly to remove surface starch; otherwise they will become sticky and clump together.
- For cold servings, plunge noodles into iced water after rinsing to keep them perfectly al dente.
Serving suggestions
This dish is perfect for packed lunches and picnics. It pairs nicely with a seaweed salad and miso soup. At home you can serve it warm with crispy tofu and a mix of stir-fried vegetables for a heartier meal.
Nut-free vegan school lunches
Creating plant-based, nut-free lunchboxes can be challenging, especially at nut-free schools. This soba recipe provides a satisfying amount of plant protein in a format kids enjoy, making it a reliable option for school lunches. I plan to share more nut-free, plant-based lunch ideas to help others facing the same challenge.

Soba Noodle FAQs
Yes. They keep well in a sealed container for 3–4 days in the fridge and are great for batch cooking at the start of the week. They do not freeze well, so consume within a few days.
No. Soba noodles are carbohydrate-based and not suitable for strict keto diets. As an alternative, you could use shirataki noodles with the same other ingredients for a lower-carb version.
