Chunky Jerusalem Artichoke and Potato Mash

This rustic Jerusalem artichoke and potato mash is a wonderful vegetarian side dish that brings a sophisticated, nutty depth to any meal. Unlike a traditional smooth puree, this version celebrates a heartier, chunky texture that pairs beautifully with seasonal roasts or savoury stews. The knobbly Jerusalem artichoke provides a delicate sweetness that balances the earthy, fluffier nature of the potatoes, creating a more complex flavour profile than your standard mash.

Ideal for those looking to introduce more root vegetable varieties into their cooking, this recipe is incredibly simple and can be prepared ahead of time to save stress in the kitchen. Using the starchy cooking water to moisten the mix ensures a lighter result, while a finishing knob of butter adds a rich, professional gloss. Serve it alongside your favourite autumnal dishes for a comforting, homemade addition to the table.
