Ternasco de Aragón at Casa Lac, Zaragoza
Casa Lac on Calle de los Mártires in Zaragoza's old quarter has been serving food continuously since 1825, making it one of the oldest restaurants in Spain — and it remains the definitive address to eat ternasco, the milk-fed Aragonese lamb that carries its own EU Protected Geographical Indication.
What Makes Ternasco Unmissable
Ternasco de Aragón is lamb slaughtered before 90 days old and raised exclusively in Aragon on its mother's milk and local cereals. The result is meat so pale it almost looks like veal, with a delicate flavour completely free of the gamey edge that puts some diners off lamb.
At Casa Lac it arrives roasted in a traditional clay cazuela with nothing more than garlic, lard, white wine and a branch of rosemary — a preparation unchanged for generations. The skin crisps to a deep mahogany while the inside stays yielding and juicy.
Order the migas aragonesas as a starter: breadcrumbs fried with chorizo, grapes and a fried egg — a shepherd's dish that somehow tastes better than the sum of its humble parts.
The Room and the Ritual
The dining room retains its 19th-century tiled walls, dark wood panelling and white linen — a setting that feels like eating inside a Goya painting. Lunch is the main meal in Aragon; arrive between 14:00 and 15:00 to eat alongside local families celebrating birthdays and communions.
Pair the ternasco with a Denominación de Origen Cariñena red — robust Garnacha-based wines from the hills south of Zaragoza that are still criminally underpriced compared to their Rioja neighbours.
