A new recipe transforms leftover pastry trimmings into speedy upside-down onion tartlets, inspired by the viral TikTok trend. The dish is a fast version of the French classic pissaladière, skipping traditional pastry-making and onion caramelisation steps.
The recipe uses one red onion, olive oil, honey, anchovies, black olives, and 120g of pastry. The onion is sliced into thick rounds and placed on a lined tray with oil, honey, and anchovies underneath. After a brief stovetop cook, pastry rectangles are laid on top and baked until golden.
Once baked, the tray is flipped to reveal caramelised onion tartlets. The method works with puff or shortcrust pastry and can be halved if less pastry is available. The dish offers a playful, spontaneous treat from kitchen scraps.
