Portuguese octopus dish
Polvo à lagareiroPolvo à lagareiro with batatas a murro and lettuce.Place of origin PortugalMain ingredientsOctopus, batatas a murro, olive oil, olives, grelos, and garlic  Media: Polvo à lagareiro Polvo à Lagareiro is a Portuguese dish based on octopus, olive oil, potatoes (batatas a murro), grelos and garlic. Its origin is uncertain though it is a common dish in Trás-os-Montes Province. It is often served on Christmas Eve. The term lagareiro refers to someone who works in an olive oil mill (lagar) in the production of olive oil. It is used in this context because of the abundant amount of olive oil poured over the octopus.
Why Polvo à Lagareiro belongs on the Christmas table
Octopus has long been a festive favourite in Portugal, and Polvo à Lagareiro brings together the season’s most indulgent flavours. The generous drizzle of cold‑pressed olive oil – a nod to the traditional lagar workers – adds richness that pairs perfectly with cold winter evenings. The dish’s hearty side of batatas a murro, crisp grelos and briny olives create a balanced plate that feels both comforting and celebratory, making it a natural centrepiece for Christmas Eve feasts where families gather around a long table.
Buying guide: picking the best octopus and olives
When shopping for Polvo à Lagareiro, look for fresh octopus with firm, white flesh and a mild sea scent; frozen, pre‑cleaned octopus works too if you’re short on time. Choose extra‑virgin olive oil with a fruity, slightly peppery finish – it will shine through the slow‑cooked dish. For olives, opt for Portuguese Galega or Arbequina varieties, which offer the right balance of bitterness and fruitiness. Finally, select small, waxy potatoes for the batatas a murro; their creamy interior holds up well to the hearty drizzle of oil.
How to serve it like a Portuguese host
After the octopus has been simmered and baked to a perfect tenderness, arrange it on a rustic platter and liberally spoon over the infused olive oil. Scatter the smashed batatas a murro around the centre, drizzle them with the same oil, and garnish with sautéed grelos and whole olives. A squeeze of fresh lemon just before serving brightens the flavours and cuts through the richness. Accompany the plate with a crisp Vinho Verde or a light red from the Douro – both keep the palate refreshed for the rest of the Christmas spread.
