This vibrant vegan noodle dish brings a fresh, contemporary twist to traditional Japanese flavours. By combining earthy soba noodles with a punchy, herb-rich green chilli pesto, you create a meal that is both light and deeply satisfying. The use of white miso adds a savoury depth that perfectly balances the citrusy zing of lime and the heat from the serrano chillies, while the watercress provides a peppery crunch.
Ideal for a quick midweek dinner or a nutritious packed lunch, these noodles are as versatile as they are colourful. The recipe is packed with fresh coriander and basil, making it a fantastic way to enjoy high-quality seasonal herbs. Serve it chilled or at room temperature, topped with toasted sesame seeds for an extra layer of nutty flavour and texture.

How to make Soba with Green Chilli Pesto
Back to contentsCook noodles in a large pot of boiling salted water until al dente, about 5 minutes. Drain, reserving 60ml soba cooking liquid.
