🥗 Ingredients

The Star Ingredient

  • 2 pounds Salted Dried Cod (Bacalao) (skinless and boneless preferred)

The Sofrito and Sauce

  • 1 cup Extra Virgin Olive Oil (Spanish oil recommended for authenticity)
  • 2 large White Onions (finely diced)
  • 8 pieces Garlic Cloves (minced)
  • 3 pounds Roma Tomatoes (roasted, peeled, and pureed)
  • 2 tablespoons Tomato Paste (for depth of color)
  • 2 cups Roasted Red Bell Peppers (sliced into thin strips)

The Texture and Brine

  • 1 cup Manzanilla Olives (pitted and stuffed with pimento)
  • 1/2 cup Non-pareil Capers (rinsed)
  • 1/2 cup Slivered Almonds (toasted)
  • 1/3 cup Golden Raisins (optional, for a hint of sweetness)
  • 1.5 pounds Baby Yukon Gold Potatoes (boiled until tender, peeled and halved)
  • 6-8 pieces Pickled Chiles Largos (Güero Chiles) (whole, from a jar)

Herbs and Seasoning

  • 1 bunch Fresh Parsley (finely chopped)
  • 3 pieces Bay Leaves (dried)
  • 1 teaspoon Black Pepper (freshly cracked)

👨‍🍳 Instructions

  1. 1

    Begin by desalinating the cod: Rinse the fish under cold water to remove surface salt. Place in a large bowl, cover with cold water, and refrigerate for 24 to 48 hours, changing the water at least 4-5 times.

  2. 2

    Drain the fish and place it in a pot of fresh simmering water. Cook for 10-15 minutes until it flakes easily. Drain, remove any stray bones or skin, and shred the fish into medium-sized chunks. Do not over-shred; you want meaty pieces.

  3. 3

    In a large, heavy-bottomed Dutch oven or 'cazuela', heat the olive oil over medium-low heat. Add the diced onions and cook slowly for about 10-12 minutes until translucent and soft, but not browned.

  4. 4

    Stir in the minced garlic and cook for another 2 minutes until fragrant. Add the tomato paste and stir frequently for 3 minutes to caramelize the sugars.

  5. 5

    Pour in the pureed roasted tomatoes and add the bay leaves. Simmer the sauce on medium-low for 20 minutes, allowing it to thicken and the oil to begin separating from the tomatoes.

  6. 6

    Carefully fold the shredded cod into the tomato sauce. Ensure the fish is well-coated but handle gently to maintain texture.

  7. 7

    Add the sliced roasted red peppers, olives, capers, toasted almonds, and raisins. Stir to combine.

  8. 8

    Gently nestle the pre-cooked potato halves into the mixture. The potatoes will absorb the savory juices of the sauce.

  9. 9

    Place the whole pickled chiles on top and pour in 2-3 tablespoons of the pickling liquid from the jar for a zesty kick.

  10. 10

    Cover and simmer on very low heat for 25-30 minutes. This allows the flavors to 'marry' (sazón). Taste before adding any salt; the cod and olives usually provide enough salinity.

  11. 11

    Remove the bay leaves and stir in the fresh chopped parsley just before serving to provide a burst of color and freshness.

💡 Chef's Tips

Be patient with the desalination; if the fish is too salty, the entire dish will be ruined. Always taste a small piece of fish after soaking to check. Use a high-quality Spanish olive oil, as it acts more like an ingredient than a cooking fat in this recipe. If the sauce looks too dry, add a splash of white wine or the water used to boil the potatoes. Always make this a day in advance! The flavors intensify and the texture improves significantly after a night in the refrigerator. Avoid over-stirring once the fish and potatoes are in the pot to prevent the dish from becoming a mushy paste.

🍽️ Serving Suggestions

Serve warm with 'bolillos' or crusty French bread to soak up the delicious oil and sauce. Pair with a crisp, dry white wine like an Albariño or a light Mexican lager. For a traditional Mexican breakfast the next day, use the leftovers to make 'tortas de bacalao' (sandwiches). Serve alongside a simple green salad with a citrus vinaigrette to cut through the richness of the stew. Accompany with a glass of festive Ponche Navideño for the full holiday experience.
