Portugal’s identity is deeply intertwined with the sea. From its rugged Atlantic coastline to its historic maritime explorations, fish has long been a cornerstone of Portuguese culture, cuisine, and daily life. Among the many varieties enjoyed across the country, one fish stands head and shoulders above the rest—not for being caught locally, but for its unparalleled cultural significance and culinary versatility. That fish is bacalhau, the Portuguese name for salted and dried cod. In this comprehensive article, we explore why bacalhau is the most consumed fish in Portugal, how it rose to prominence, and the myriad ways it continues to shape Portuguese gastronomy.
The Reign of Bacalhau: Portugal’s National Fish
While Portugal boasts a rich diversity of fresh seafood—sardines, octopus, monkfish, and horse mackerel to name a few—none surpass bacalhau in terms of consumption and cultural importance. Despite not being native to Portuguese waters, bacalhau has become a national staple, with the Portuguese reportedly consuming over 120,000 tons annually, making Portugal the largest per capita consumer of cod in the world.
What Is Bacalhau?
Bacalhau refers specifically to Atlantic cod (Gadus morhua) preserved through salting and drying. The preservation method dates back centuries when refrigeration didn’t exist, allowing fish to be transported and stored over long periods. This process not only gave cod an extended shelf life but also enhanced its distinct flavor profile—dense, slightly salty, and rich in texture.
The transformation from fresh cod to bacalhau involves:
- Catch of cod typically from the North Atlantic (Norway, Iceland, and Newfoundland regions)
- Immediate salting—layers of cod packed in salt—often done at sea or within hours of catch
- Drying—air-dried for several weeks in cold, clean environments
Before preparation, bacalhau must be desalted, a process known as “dessalgado,” which usually requires soaking in water for 24 to 48 hours, with the water changed multiple times.
Why Bacalhau? The Historical Roots
To understand bacalhau’s dominance in Portugal, we must travel back to the 15th and 16th centuries—the Age of Portuguese Discoveries. Portuguese explorers, including Vasco da Gama and Bartolomeu Dias, dominated the seas in search of trade routes and riches. Salted cod became indispensable for long sea voyages due to its durability, nutritional value, and ability to sustain sailors without spoiling.
Religious Influence also played a significant role. During Catholic observances, particularly Lent and Fridays, meat consumption was restricted. With over 40 meatless days per year in the liturgical calendar, fish became a dietary necessity. Bacalhau, preserved and available year-round, proved ideal.
By the 16th century, Portugal established extensive trade networks with Nordic countries, importing massive quantities of cod. This trade relationship solidified bacalhau’s place in every kitchen, from coastal villages to inland towns. Over time, bacalhau evolved from a preservation solution to a national symbol of resilience, tradition, and flavor.
Bacalhau in Modern Portugal: Statistics and Consumption Trends
Today, bacalhau remains a year-round fixture in Portuguese diets. While it is especially popular during holidays like Christmas and Easter, its consumption is not limited to festive occasions. According to EUROSTAT and industry reports:
| Country | Annual Cod Consumption (per capita) |
|---|---|
| Portugal | Over 30 kg |
| Spain | ~ 7 kg |
| Norway | ~ 5 kg |
| USA | ~ 2 kg |
These figures underscore the exceptional nature of Portuguese bacalhau consumption. The average Portuguese person will eat roughly one kilogram of bacalhau per month—equivalent to about 365 different documented recipes said to exist in the country.

Cultural Significance: Why Bacalhau Is More Than Just a Meal
Bacalhau transcends food in Portugal—it’s a symbol of national identity, family, and celebration.
Family Gatherings and Holiday Traditions
No Portuguese Christmas dinner is complete without bacalhau. The main meal on December 24th often features Bacalhau com Natas or Bacalhau à Brás, a tradition so ingrained that supermarkets see dramatic spikes in sales weeks before the holidays. Families gather around the table to enjoy this ritual dish, which fosters connection and continuity across generations.
Easter and other religious holidays also feature bacalhau prominently, honoring centuries-old customs rooted in Catholic fasting practices.
A Culinary Heritage Recognized Worldwide
UNESCO and culinary institutions have acknowledged Portugal’s bacalhau tradition as an intangible cultural heritage. The diversity of recipes and the skill required in preparing properly desalted bacalhau are part of what makes Portuguese cuisine unique. Food tours in Lisbon, Porto, and the Algarve often include bacalhau tastings as a centerpiece of the experience.
Bacalhau in Festivals and Markets
Many Portuguese towns host fish-centric festivals, especially during Lent, where bacalhau dishes are celebrated with cooking competitions, street vendors, and communal meals. In places like Óbidos and Aveiro, visitors can attend bacalhau festivals featuring dozens of creative variations, from bacalhau-stuffed pastries to bacalhau risotto.
Markets across Portugal, like Lisbon’s Mercado da Ribeira or Porto’s Mercado do Bolhão, showcase bacalhau in various forms—whole dried fish, pre-soaked fillets, or ready-to-cook kits. Vendors pride themselves on sourcing high-quality dried cod, often imported from Norway through traditional trade channels.
Economic and Environmental Aspects of Bacalhau Consumption
The widespread love for bacalhau has significant economic and environmental implications.
Imports and Trade Relationships
Portugal relies almost entirely on imported cod. The primary sources are:
- Norway – The largest exporter to Portugal, supplying high-quality, air-dried cod (klippfisk)
- Iceland – Known for its pristine waters and sustainable fishing practices
- Canada and Greenland – Historically important, especially during the 20th century
These imports create a strong trade relationship between Portugal and Nordic nations, with cod shipments arriving by sea and air weekly. The Portuguese diaspora in Canada also helps maintain this trade network, particularly in cities like Toronto and Montreal.
Sustainability Concerns
With growing awareness of ocean conservation, questions about the sustainability of cod fishing have emerged. Overfishing in the 20th century led to dramatic drops in cod stocks, especially in the Northwest Atlantic. Today, most imported bacalhau into Portugal comes from MSC-certified (Marine Stewardship Council) sustainable fisheries, particularly in Norway and Iceland.
Portuguese consumers and chefs are increasingly prioritizing responsibly sourced bacalhau, driving demand for traceable and eco-friendly options. Some chefs are experimenting with alternatives—like fresh local cod or lab-grown seafood—but none have displaced traditional bacalhau.
Environmental Impact of Drying and Salting
Unlike refrigerated transport, the salting and drying process requires less energy, making bacalhau a relatively low-carbon food option when compared to fresh fish flown over long distances. However, salt production and water use during desalting are areas that could benefit from more efficient, sustainable practices.
Beyond Bacalhau: Other Popular Fish in Portugal
Though bacalhau reigns supreme, Portugal’s diverse marine ecosystem supports a wide variety of other commonly consumed fish.
Sardines: The Summer Star
No discussion of Portuguese fish would be complete without mentioning sardines. During the summer months, especially June and July, grilled sardines are the star of festivals like Lisbon’s Festas de Santo António. Served with boiled potatoes, bell peppers, and a drizzle of olive oil, sardines are a quintessential Portuguese summer treat.
Octopus and Swordfish: Coastal Delicacies
In coastal regions, octopus (polvo) is often prepared as Polvo à Lagareiro, roasted with olive oil and garlic. Swordfish (espadarte) is grilled and served with tomato and onion salad, particularly in the Algarve.
Other Common Varieties
- Robalo (Bass): Often grilled and served whole
- Pescada (Hake): Used in stews and fried preparations
- Peixe Espada (Black Scabbard Fish): A deep-sea fish popular in Madeira
- Chicharro (Horse Mackerel): Fried or stewed, common in Azores and coastal towns
While these fish are beloved, none approach bacalhau in terms of volume consumed or cultural symbolism.
How to Prepare Bacalhau at Home: A Step-by-Step Guide
For those eager to try authentic Portuguese cooking, preparing bacalhau at home is a rewarding experience.

So, the next time you visit Portugal or explore its cuisine abroad, remember: to understand the Portuguese palate, you must first fall in love with bacalhau.
What is bacalhau, and why is it so significant in Portuguese cuisine?
Bacalhau is the Portuguese word for salted and dried codfish, traditionally sourced from the North Atlantic, particularly from regions near Norway, Iceland, and Newfoundland. This preservation method dates back centuries, when refrigeration did not exist, and allowed fish to be stored and transported over long distances without spoiling. The salting and drying process intensifies the flavor and changes the texture of the fish, making it a unique ingredient in many traditional dishes. Bacalhau became a cornerstone of the Portuguese diet due to its availability, durability, and versatility in cooking.
The cultural significance of bacalhau in Portugal extends beyond mere nutrition—it’s deeply woven into national identity and tradition. It’s often said that there are over 1,000 ways to prepare bacalhau in Portugal, reflecting its enduring popularity and adaptability. From festive holiday meals to everyday family dinners, bacalhau is a symbol of Portuguese heritage and maritime history. Its importance peaked during the Age of Exploration, when Portuguese sailors relied on it as a staple protein during long sea voyages, cementing its role in the country’s culinary legacy.
Why is salted cod preferred over fresh cod in Portugal?
Salted cod became the preferred form of cod in Portugal due to practical and historical reasons rooted in preservation techniques. Before the advent of modern refrigeration, salting and drying fish was one of the most effective ways to prevent spoilage during long storage periods and maritime transport. Portuguese fishermen and traders would travel vast distances, and salted cod could last for months without refrigeration, making it ideal for provisioning ships and supplying coastal communities. This method also allowed Portugal to import cod from distant fishing grounds, especially during seasons when local fish were scarce.
Additionally, the flavor and texture of rehydrated salted cod are distinct and highly prized in Portuguese cuisine. The salting process draws out moisture, concentrating the flavor and giving the fish a firmer, denser texture once soaked and cooked. Many traditional recipes rely on this specific quality, and the rehydration process—soaking the fish in water for 24 to 48 hours—has become a ritual in Portuguese households. Over time, preference for salted cod became embedded in culinary traditions, making fresh cod far less common in Portuguese dishes.
Where does Portugal source its bacalhau from today?
Despite being a coastal nation, Portugal does not harvest significant amounts of cod from its own waters, as Atlantic cod populations in southern regions are limited. Instead, the country imports the vast majority of its bacalhau from northern Atlantic waters, primarily from Norway, Iceland, and Greenland. These cold, deep waters are ideal for cod, producing high-quality fish that are well-suited for salting and drying. Portuguese importers maintain longstanding trade relationships with these nations, ensuring a steady supply of raw cod for processing.
Once imported, the cod is either processed into salted-dried form abroad or prepared locally following traditional methods. Norwegian cod, in particular, is highly regarded for its texture and flavor, making it the most sought-after variety. The importation of bacalhau highlights Portugal’s deep connection to global maritime trade routes, echoing centuries of seafaring tradition. Even today, the arrival of bacalhau shipments is often celebrated in fishing communities, symbolizing continuity with the past.
How is bacalhau prepared before cooking?
Before bacalhau can be used in cooking, it must undergo a rehydration process to remove excess salt and restore moisture. This typically involves soaking the dried, salted fish in cold water for 24 to 48 hours, with the water changed several times to gradually draw out the salt. The exact duration depends on the thickness of the fish and the desired saltiness. Some households even follow regional or family-specific soaking techniques passed down through generations.
After soaking, the bacalhau is ready to be cooked. It is commonly desalted to a mild level, allowing the salt to enhance rather than overpower the dish. At this stage, the fish flakes easily and develops a tender yet firm texture when cooked. Proper preparation is crucial, as under-soaked bacalhau can be overly salty, while over-soaking may dilute flavor and degrade texture. This meticulous pre-cooking ritual underscores the respect and care with which Portuguese people treat this national ingredient.
What are some popular dishes made with bacalhau in Portugal?
One of the most famous bacalhau dishes in Portugal is Bacalhau à Brás, a comforting combination of shredded cod, thinly sliced potatoes, onions, and scrambled eggs, often garnished with parsley and black olives. This dish originated in Lisbon and is beloved for its creamy texture and balanced flavors. Another classic is Bacalhau com Natas, which features cod baked in a rich cream and potato sauce, offering a decadent twist on the traditional staple.
Other notable preparations include Bacalhau Assado, where the fish is oven-roasted with garlic, olive oil, and vegetables, and Bacalhau à Gomes de Sá, a casserole-style dish layered with potatoes, onions, hard-boiled eggs, and olives. In coastal towns, grilled bacalhau with olive oil and lemon is a common seafood option. Each region of Portugal boasts its own variation, reflecting local tastes and ingredients, but all highlight the versatility and central role of bacalhau in the national diet.
Is bacalhau consumed year-round, or is it reserved for special occasions?
Bacalhau is enjoyed year-round in Portugal and appears regularly in both home cooking and restaurant menus across the country. Its availability and cultural importance mean it is not limited to specific seasons or holidays. Many families have weekly routines that include a bacalhau dish, particularly on weekends or Fridays, in line with Catholic traditions of abstaining from meat. Supermarkets and fishmongers consistently stock salted cod, often in various cuts and degrees of salting to suit different recipes.
However, bacalhau holds particular prominence during religious and national celebrations. It is a staple on the Christmas Eve dinner table, where families gather to enjoy dishes like Bacalhau à Lagareiro—cod roasted with garlic, olive oil, and boiled potatoes. It also features in Easter meals and other festive occasions. This dual role—as both an everyday comfort food and a ceremonial dish—demonstrates how deeply bacalhau is embedded in Portuguese life, bridging the ordinary and the extraordinary.
What historical events contributed to bacalhau’s dominance in Portuguese cuisine?
The rise of bacalhau in Portuguese cuisine can be traced back to the 15th and 16th centuries during the Age of Portuguese Exploration. As sailors embarked on long voyages to Africa, India, and the Americas, they needed non-perishable food sources, and salted cod proved ideal due to its long shelf life and high protein content. The Catholic Church’s dietary rules, which mandated fish consumption on fast days (such as Fridays and Lent), further increased demand for preserved fish like bacalhau, which could be stored and used reliably throughout the year.
By the 18th century, trade routes had firmly established a steady supply of cod from Northern Europe, and Portuguese merchants developed strong economic ties with cod-producing nations. This consistent access, combined with religious customs and maritime necessity, solidified bacalhau’s place in the national diet. Over generations, it evolved from a practical food source into a cherished cultural symbol. Even as modern refrigeration made fresh fish more accessible, the tradition of eating bacalhau endured, a testament to its historical roots and enduring appeal.
