Udon with Mushroom Broth, Cabbage, and Yams

This vegan udon noodle soup is a masterclass in building deep, savoury flavours through a fragrant, home-made mushroom broth. Infused with aromatic lemongrass, ginger and kombu, the clear soup provides a delicate yet complex base for the nutrient-dense vegetables. The combination of earthy yams, crunchy snow peas and vibrant carrots creates a beautiful textural contrast against the thick, chewy Japanese-style noodles, making this a truly satisfying plant-based lunch or dinner.

As a heart-healthy and light meal, this dish is perfect for those seeking a restorative dinner that doesn't compromise on taste. The preparation can be conveniently split over two days, as the broth develops even more character when left to infuse overnight in the fridge. Serve it in deep warmed bowls with a side of spicy sambal oelek for a customisable heat that perfectly complements the ginger-led broth.

How to make Udon with Mushroom Broth, Cabbage, and Yams

Bring broth and 725ml water to simmer in large pot over medium heat. Add coriander, mushrooms, sliced ginger, and lemongrass. Cover; simmer until mushrooms are tender, about 30 minutes. Rinse kombu; add to broth. Simmer 1 minute. Using tongs, remove kombu and mushrooms; discard kombu. Transfer mushrooms to work surface; cut off stems and discard. Cut each mushroom into 3 to 4 strips. Strain broth through fine-mesh strainer into another large pot; discard solids in strainer. Add tamari and rice vinegar to broth. DO AHEAD: Can be made 1 day ahead. Cover and chill mushrooms. Cool, cover, and chill broth.

Bring large pot of salted water to boil. Cook yams until just tender, 4 to 5 minutes. Using skimmer, transfer to medium bowl. Cook snow peas, cabbage, and carrots separately until crisp-tender (snow peas, 30 seconds; cabbage, 1 1/2 minutes; carrots, 2 minutes). Using skimmer, transfer vegetables to separate bowls. Reserve cooking liquid. DO AHEAD: Vegetables can be cooked 2 hours ahead. Let vegetables and liquid stand at room temperature.

Bring cooking liquid to boil. Sprinkle with salt. Add noodles; cook until tender but still firm to bite, stirring often. Drain; rinse.

Meanwhile, bring vegetable broth to simmer. Add spring onions and ginger strips. Season with salt and pepper.

Using tongs, divide noodles among bowls. Divide mushrooms, yams, snow peas, cabbage, and carrots among bowls, each in separate mound. Divide tofu, if using, among bowls. Ladle broth over and serve, passing sambal oelek and tamari separately.
