This elegant warm onion tart with thyme is a wonderful way to showcase the natural sweetness of slowly caramelised onions. By gently cooking the onions in butter until they reach a deep mahogany hue, you create a rich, savoury topping that contrasts beautifully with the crisp, buttery layers of golden puff pastry. The addition of fresh thyme brings a woody, aromatic note that elevates this simple vegetarian dish into something truly sophisticated.
Ideal as a refined appetiser for a dinner party or as a quick gourmet snack, these bite-sized tarts are incredibly versatile. Using shop-bought puff pastry makes this recipe both accessible and time-efficient without compromising on flavour or texture. You can prepare the thyme-scented onions in advance and simply assemble and bake the pastry rounds just before your guests arrive for a stress-free hosting experience.
