Mushrooms with Garlic Butter

This classic vegetarian side dish brings together the earthy flavour of roasted white mushrooms with a rich, aromatic garlic butter. By roasting the mushrooms until they are tender and juicy, you create a natural sauce that is perfectly offset by the addition of fresh flat-leaf parsley and seasoning. It is a simple yet sophisticated way to elevate the humble button mushroom into something truly special for a mid-week meal or as a savoury accompaniment to a Sunday roast.

To add a delightful contrast in texture, these mushrooms are tossed with golden, homemade croûtons that provide a satisfying crunch in every bite. This recipe is an excellent choice for those seeking a quick, comforting addition to their repertoire that relies on simple larder staples. Serve these buttery mushrooms alongside a crisp green salad or as a delicious topping for a thick slice of toasted sourdough.
