Polvo à lagareiro: octopus in olive oil
The Portuguese counterpart to bacalhau à lagareiro — whole tentacles of Atlantic octopus (polvo), first tenderised by boiling, then roasted in a generous bath of olive oil, garlic, and bay leaf in a cast iron or earthenware vessel at high heat until the skin blisters and the tips of the tentacles begin to caramelise. The lagareiro technique — drowning the ingredient in olive oil during roasting — transforms the boiled octopus into something simultaneously crisp at the extremities and silky at the thicker sections. Portugal is Europe's largest consumer of octopus per capita, and the tentacles cooked in olive oil with roasted potatoes is one of the most photographed Portuguese restaurant dishes.

The Method
1
If the octopus has not been frozen for 48 hours, submerge it in a large pot of plain unsalted water and bring to a gentle boil. Cook for 45–60 minutes. The dish is done at this stage when a thin-bladed knife passes through the thickest section of a tentacle without resistance.
2
Lift the octopus from the water and drain thoroughly. Pat the surface as dry as possible before it enters the roasting vessel — residual water fights the oil bath and prevents crisping.
3
Heat the oven to 220 °C. Arrange the octopus tentacles in a single layer in a cast-iron or earthenware roasting dish. Scatter the smashed garlic and bay leaves across the pan, then pour the olive oil over and around until the tentacles are generously bathed — not merely filmed. This is where the dish lives or dies: too little oil and the lagareiro technique fails; the tentacles will tighten and dry rather than roast silky.
4
Roast at 220 °C for 20–25 minutes. The dish is done when the skin at the tips of the tentacles blisters and the very ends begin to colour to a deep caramel bronze, while the thicker sections remain yielding. The oil in the pan will be fragrant with octopus juices, garlic, and bay.
5
If roasting potatoes in the same dish, add the halved waxy potatoes to the olive oil bath before the octopus goes in, or transfer them to a separate tray and ladle some of the infused cooking oil over them at the halfway point. They are done when golden on the cut face and tender through to the centre when pressed.
6
Serve the octopus in its cooking oil, with the potatoes alongside. Spoon the garlic-and-bay-infused oil from the pan over the whole dish at the table.

Quality Hierarchy
01
Reserve — A whole wild Atlantic octopus, frozen 48 hours then thawed, tenderised without boiling — the freeze alone breaks the muscle fibres. Finished in a single-estate Portuguese extra-virgin olive oil of pronounced character.
02
Estate — Wild Atlantic octopus, boiled 45–60 minutes in plain water until a knife passes freely, drained and dried well. A good-quality Portuguese or Spanish extra-virgin olive oil for the bath.
03
Market — Pre-cleaned octopus from a reliable fishmonger, boiled to tenderness. A sound extra-virgin olive oil of neutral provenance. Dried bay leaves.
04
House — Frozen pre-cut octopus tentacles, thawed and boiled until tender. Any extra-virgin olive oil in sufficient quantity to maintain the oil bath. The technique still holds; only the depth of flavour diminishes.

Sensory Tests
◇Touch. A thin-bladed knife passes through the thickest part of a tentacle without resistance after 45–60 minutes of boiling — the octopus is tenderised and ready for the oven.
◇Sight. The olive oil completely submerges or generously bathes the tentacles in the roasting dish — the lagareiro condition is met.
◇Sight. Skin at the tips of the tentacles blisters and the extremities have begun to caramelise to a deep bronze after 20–25 minutes at 220 °C.
◇Smell. The oil in the pan is fragrant with octopus juices, garlic, and bay — the infusion is complete and the dish is ready to serve.
◇Where it lives or dies. The octopus must enter a generous bath of olive oil in the roasting vessel — reduce the oil and the lagareiro technique collapses, yielding tight, dry tentacles rather than the dish's defining contrast of crisp tip and silky body.
