Spread the love

Bacalao al Pil-Pil is a classic dish from the Basque Country in northern Spain, known for its simplicity and exquisite flavors. This dish highlights the region’s culinary expertise by combining salted cod with olive oil, garlic, and a touch of chili, creating a rich, emulsified sauce. The preparation may seem straightforward, but it requires a bit of finesse to achieve the perfect texture and flavor.

The Origins of Bacalao al Pil-Pil

The Basque Country, a region renowned for its rich culinary traditions, has long been associated with exceptional seafood dishes. Bacalao al Pil-Pil is one such dish that showcases the ingenuity of Basque cuisine. “Pil-Pil” refers to the sound made by the bubbling oil as the dish cooks, and it’s a technique that involves emulsifying the olive oil with the gelatin released from the cod to create a luxurious sauce.

Historically, salted cod (bacalao) became a staple in Spanish cuisine due to its long shelf life and ease of transportation. The Basques, with their deep connection to the sea, embraced bacalao and created numerous recipes that celebrate its unique flavor and texture.

Ingredients for Bacalao al Pil-Pil

To prepare Bacalao al Pil-Pil, you’ll need the following ingredients:

  • For the Cod:
    • 4 pieces of salted cod fillets (about 200g each)
    • Cold water (for soaking the cod)
  • For the Pil-Pil Sauce:
    • 200ml extra virgin olive oil
    • 6 cloves garlic, thinly sliced
    • 1-2 dried red chili peppers, deseeded and torn into pieces
    • Fresh parsley, chopped (for garnish)


Step 1: Desalinate the Cod
  1. Soak the Cod: Rinse the salted cod fillets under cold running water to remove excess salt. Place the fillets in a large bowl and cover them with cold water. Soak for 24-48 hours, changing the water every 8 hours to remove the salt gradually.
Step 2: Prepare the Pil-Pil Sauce
  1. Heat the Oil: In a large, deep skillet or pan, heat the extra virgin olive oil over low heat.
  2. Infuse with Garlic and Chili: Add the thinly sliced garlic and dried chili peppers to the oil. Cook gently, stirring occasionally, until the garlic becomes golden and fragrant, but not burned. This process should take about 10 minutes. Remove the garlic and chili from the oil and set them aside for later use.
Step 3: Cook the Cod
  1. Prepare the Cod: After desalination, pat the cod fillets dry with paper towels.
  2. Cook the Cod in Oil: Increase the heat slightly to medium-low. Add the cod fillets to the pan, skin-side down. Cook gently, shaking the pan occasionally, until the fish begins to release its gelatin and the skin becomes crispy. This should take about 10-15 minutes.
Step 4: Emulsify the Sauce
  1. Remove the Cod: Carefully remove the cod fillets from the pan and set them aside, keeping them warm.
  2. Create the Emulsion: To create the pil-pil sauce, you need to emulsify the gelatin released by the cod with the olive oil. Using a small strainer or whisk, gently stir the oil in circular motions until it thickens and emulsifies into a creamy sauce. This process may take some patience, but the result is worth it.
Step 5: Combine and Serve
  1. Return the Cod: Once the sauce is ready, return the cod fillets to the pan, spooning the sauce over them to coat evenly. Add the reserved garlic and chili back to the pan.
  2. Garnish and Serve: Sprinkle with chopped fresh parsley. Serve Bacalao al Pil-Pil hot, accompanied by crusty bread to soak up the delicious sauce.

Tips and Variations

  • Temperature Control: The key to perfect Bacalao al Pil-Pil is maintaining a low and steady heat. This prevents the cod from overcooking and ensures the sauce emulsifies properly.
  • Garlic and Chili: Adjust the amount of garlic and chili to suit your taste. Some prefer a more garlicky or spicier sauce.
  • Presentation: Serve the dish in a clay cazuela (Spanish terracotta dish) for an authentic Basque presentation.

Nutritional Benefits

Bacalao al Pil-Pil is not only a treat for the palate but also packed with nutrients. Cod is a lean source of protein and provides essential vitamins and minerals, including vitamin B12, selenium, and iodine. Olive oil, a cornerstone of Mediterranean cuisine, is rich in monounsaturated fats and antioxidants, contributing to heart health.


Bacalao al Pil-Pil is a shining example of Basque culinary tradition, showcasing the simplicity and elegance of its ingredients. The combination of tender, salted cod with the rich, garlicky pil-pil sauce creates a dish that is both comforting and sophisticated. Whether you are a seasoned cook or a novice in the kitchen, preparing Bacalao al Pil-Pil is an opportunity to experience the flavors and techniques of Basque cuisine. Enjoy this culinary gem and savor the taste of northern Spain.
