Bacalao, also known as salt cod, is a culinary staple in many parts of the world, particularly in Portugal, Spain, Italy, and the Caribbean. This preserved fish, typically cod, is dried and heavily salted, a process that dates back centuries as a method of preserving food before refrigeration. The preparation of bacalao is a multi-step process that requires patience and understanding to transform the intensely salty, dried fish into a delectable dish. This article delves into the intricacies of preparing bacalao, covering everything from the initial soaking process to various cooking methods and regional variations.
The Foundation: Soaking and Desalting Bacalao
The most crucial step in preparing bacalao is the desalting process. The heavy salting that preserves the fish makes it inedible in its dried state. Proper soaking is essential to remove excess salt and rehydrate the fish, restoring its texture and flavor. This process can take several days, depending on the thickness of the fish and the amount of salt it contains.
Choosing the Right Bacalao
Before you even begin soaking, it’s important to choose your bacalao wisely. Salt cod comes in various qualities and thicknesses. Thicker cuts generally require longer soaking times. Examine the fish for any signs of discoloration or damage before purchasing.
The Soaking Process: A Step-by-Step Guide
The soaking process is relatively simple, but it demands patience and consistency. Here’s how to do it:
- Rinse the bacalao under cold running water to remove any surface salt.
- Place the bacalao in a large bowl or container filled with cold water. Ensure the fish is completely submerged.
- Refrigerate the bowl of bacalao. This is crucial to prevent bacterial growth.
- Change the water every 6-8 hours. This frequent water change is key to effectively removing the salt.
- Continue this process for 24-72 hours, or even longer, depending on the thickness of the fish and your taste preference. Taste a small piece of the bacalao after each day to gauge its saltiness.
Tips for Effective Desalting
Several factors can influence the desalting process. Using very cold water is paramount. Warm water can encourage bacterial growth and negatively impact the texture of the fish. Similarly, always refrigerate the bacalao during soaking. Some cooks add a potato to the soaking water; the potato is believed to absorb some of the salt. While anecdotal, it’s a harmless addition. Lastly, remember that the goal is not to remove all the salt entirely, but to reduce it to a palatable level. A slight saltiness is often desirable and enhances the flavor of the bacalao.
Bacalao Preparation Techniques: Cooking Methods
Once the bacalao is properly desalted, the culinary possibilities are endless. It can be boiled, baked, fried, grilled, or used in stews and casseroles. Each cooking method imparts a unique texture and flavor to the fish.
Boiling: A Gentle Approach
Boiling is a simple and gentle way to cook bacalao. It’s often used as a base for other dishes or when the fish needs to be shredded or flaked.
To boil bacalao, place the desalted fish in a pot and cover it with cold water. Bring the water to a simmer and cook for 10-15 minutes, or until the fish is easily flaked with a fork. Be careful not to overcook the bacalao, as it can become tough. Once cooked, drain the fish and use it in your desired recipe.
Baking: Enhancing Flavor
Baking bacalao allows for greater flavor infusion. It can be baked with various vegetables, herbs, and sauces.
To bake bacalao, preheat your oven to 375°F (190°C). Arrange the desalted bacalao in a baking dish. Add your desired vegetables, such as potatoes, onions, and peppers. Drizzle with olive oil and season with herbs like garlic, parsley, and paprika. Bake for 20-30 minutes, or until the fish is cooked through and the vegetables are tender.
Frying: Crispy and Delicious
Frying bacalao creates a crispy exterior and a tender interior. This method is popular for making fritters or serving the fish as a standalone dish.
To fry bacalao, pat the desalted fish dry with paper towels. Dredge it in flour or a light batter. Heat oil in a frying pan over medium-high heat. Fry the bacalao for 3-5 minutes per side, or until golden brown and cooked through. Be careful not to overcrowd the pan, as this will lower the oil temperature and result in soggy fish.
Grilling: A Smoky Char
Grilling bacalao imparts a smoky flavor that complements the fish’s natural taste. This method is best suited for thicker cuts of bacalao.
To grill bacalao, brush the desalted fish with olive oil and season with salt, pepper, and your favorite herbs. Preheat your grill to medium heat. Grill the bacalao for 5-7 minutes per side, or until cooked through and slightly charred.
Regional Variations in Bacalao Dishes
Bacalao is a versatile ingredient with a rich culinary history, resulting in a wide array of regional dishes. Each region has its unique take on preparing and serving salt cod.

What exactly is bacalao, and how is it different from other types of cod?
Bacalao, also known as salt cod, is cod that has been preserved through salting and drying. This process significantly extends its shelf life and concentrates its flavor. It differs from fresh cod, which is simply cod that has not undergone any preservation methods, and from frozen cod, which is preserved by freezing rather than salting and drying.
The salting and drying process not only preserves the fish but also alters its texture and flavor profile. Bacalao has a denser, chewier texture compared to fresh cod, and its flavor is significantly more intense and salty. This distinct flavor is a key component in many traditional dishes around the world.
Why is cod salted and dried in the first place?
The primary reason for salting and drying cod historically was preservation. Before refrigeration, salting and drying were crucial methods for preserving fish and making it transportable and edible over long periods. This allowed coastal communities to harvest and store cod for consumption throughout the year and trade it to inland regions.
Beyond preservation, the salting and drying process also enhances the flavor of the cod. The salt draws out moisture, concentrating the fish’s natural flavors and creating a unique taste profile that is highly prized in many cuisines. This distinctive flavor has made bacalao a staple ingredient in dishes around the world.
What is the proper way to desalt bacalao before cooking?
The most effective method for desalting bacalao involves soaking it in cold water for 24 to 72 hours, depending on the thickness of the fillet and the desired saltiness. It’s crucial to change the water every 6 to 8 hours to effectively remove the salt. Using cold water is essential, as warm water can encourage bacterial growth and negatively impact the texture of the fish.
To ensure even desalting, place the bacalao skin-side up in the water. Before cooking, taste a small piece of the fish to check for saltiness. If it’s still too salty, continue soaking for a few more hours, changing the water as before. The goal is to achieve a balance where the fish retains its flavor without being excessively salty.
What are some popular bacalao dishes from around the world?
Bacalao is a versatile ingredient featured in numerous dishes across various cultures. In Portugal, it’s said there are over 365 ways to prepare bacalao, with popular dishes including Bacalhau à Brás (shredded cod with scrambled eggs and potatoes) and Bacalhau com Natas (cod with cream and potatoes). Similarly, in Spain, you’ll find Bacalao al Pil Pil (cod cooked in garlic-infused olive oil) and croquetas de bacalao.
Other popular bacalao dishes include Italian Baccalà alla Vicentina (cod cooked in milk), French Brandade de Morue (cod purée), and Caribbean Saltfish Ackee (cod cooked with ackee fruit). These dishes highlight the adaptability of bacalao and its ability to complement a wide range of flavors and ingredients, showcasing its cultural significance.
Can you use any type of cod for bacalao?
While traditionally Atlantic cod (Gadus morhua) is the species most commonly used for bacalao, other types of cod and similar white fish can also be utilized. These might include Pacific cod or even haddock, although the resulting flavor and texture may differ slightly from traditional bacalao made with Atlantic cod.
The key consideration is the quality and freshness of the fish before the salting and drying process. A firm, white-fleshed fish will generally produce a better-quality bacalao. It’s important to ensure the fish is properly cleaned and prepared before salting to prevent spoilage and ensure the desired flavor profile.
What is the best way to store bacalao after it has been desalted?
Once bacalao has been desalted, it should be stored in the refrigerator. It’s best to keep it submerged in fresh, cold water, changing the water daily. This helps to maintain its moisture and prevent it from drying out or becoming too salty again.
Desalted bacalao is perishable and should be used within 2 to 3 days. If you don’t plan to use it within that timeframe, you can freeze it. To freeze desalted bacalao, pat it dry, wrap it tightly in plastic wrap, and then place it in a freezer-safe bag. Properly frozen bacalao can last for several months.
Are there any nutritional benefits to eating bacalao?
Bacalao, even after the salting and drying process, retains many of the nutritional benefits of fresh cod. It is a good source of lean protein, which is essential for building and repairing tissues. It’s also low in fat, making it a healthy option for those watching their fat intake.
Furthermore, bacalao contains essential nutrients like vitamin D, which is important for bone health, and omega-3 fatty acids, which are beneficial for heart health. However, it’s important to consider the salt content, especially for individuals with high blood pressure or other health concerns. Moderation is key to enjoying the nutritional benefits of bacalao without overconsuming sodium.
