British plant-based food brand This is expanding its whole food-led offering with the debut of a limited-edition Chestnut, Mushroom & Caramelised Onion Nut Roast, landing in Tesco stores from 8 December and available for three weeks only.

The new seasonal centrepiece features a blend of chestnuts, mushrooms, parsnips, seeds, and caramelised red onion chutney, created to deliver a “satisfying bite” and a depth of festive flavour. The sweet chestnut and caramelised onion are balanced with earthy mushroom, resulting in what the brand calls the “perfect festive centrepiece.”

Convenience is central to the launch: the nut roast is freezable, cooks directly in its tray, serves four people, and is priced at £7.50.

The innovation builds on This’ growing portfolio of whole food-based products, reflecting rising consumer scrutiny around ultra-processed plant-based foods. The brand first moved into this space earlier this year with the launch of This Is Super Superfood, followed by additional products including chickpea tofu.

Alongside its whole food line, This continues to offer its signature hyper-realistic plant-based meats across UK retailers — including roast chicken and stuffing alternatives, plant-based pork sausages and cocktail sausages, bacon streaks and lardons, chicken deli pieces, and beef pastrami.

To further spotlight its expanding portfolio, the brand will also open a pop-up “butcher shop” in London on 29–30 November, showcasing its full range of plant-based products.
