Polvo à Lagareiro is a beloved Portuguese dish that showcases octopus at its finest. This dish features incredibly tender octopus that's first boiled until perfectly cooked, then roasted with crushed potatoes in generous amounts of high-quality olive oil, creating a dish that's both rustic and elegant.

The name "Lagareiro" refers to workers in traditional olive oil presses, and this cooking style, which uses abundant olive oil, is a testament to Portugal's rich olive oil production heritage. The dish originated in the coastal regions of Portugal, where fresh octopus was readily available, and has since become a staple in restaurants throughout the country.

The secret to perfect Polvo à Lagareiro lies in the cooking technique. The octopus is first tenderized by slowly boiling it with onions and bay leaves - some traditional cooks even add a wine cork to the water, believing it helps tenderize the meat. Once tender, the octopus is roasted until slightly crispy on the outside while remaining succulent inside. The potatoes are first boiled, lightly smashed to create crevices, then roasted until golden with plenty of olive oil, garlic, and fresh herbs.

While the traditional recipe remains the most popular, some chefs add their own twists. Modern variations might include roasted bell peppers, caramelized onions, or a sprinkle of smoked paprika. Some regions serve it with different types of potatoes or additional vegetables, though the generous use of olive oil remains constant.

In Portuguese restaurants, Polvo à Lagareiro is often served as a main course, presented on a rustic wooden board or traditional earthenware dish. It's typically garnished with fresh parsley and accompanied by a good Portuguese wine, particularly a crisp vinho verde that complements the richness of the dish.

While delicious, this dish is quite rich due to the generous use of olive oil. Those watching their calorie intake might want to moderate their portion size. However, it's worth noting that octopus is a nutritious choice, being high in protein, low in fat, and rich in iron and vitamin B12. The olive oil, while caloric, provides healthy monounsaturated fats and antioxidants. The dish is naturally gluten-free, making it suitable for those with celiac disease or gluten sensitivity.
