Thyme-Roasted Apples and Onions

This elegant vegetarian side dish of thyme-roasted apples and onions offers a sophisticated balance of sweet and savoury flavours. By reducing apple cider into a syrupy glaze and roasting the ingredients until they reach a deep, jammy caramelisation, you create a versatile accompaniment that pairs beautifully with autumn and winter menus. The fragrance of fresh thyme cuts through the richness of the butter, providing a bright, herbaceous lift to the tray.

Ideal for serving alongside a traditional Sunday roast or as a unique addition to a festive spread, these roasted gems are both comforting and healthy. Using firm Braeburn apples ensures the fruit holds its shape during the high-heat roasting process, while the cider reduction adds a professional-quality depth of flavour. This simple yet impressive dish is a wonderful way to elevate humble seasonal produce for family and friends alike.
