 Ingredients

The Core Layers:

• 2 lbs Salted cod fish (desalted).
• 5 Large potatoes, peeled and sliced.
• 3 Large onions, sliced into rings.

The Portuguese Infusion:

• 3/4 cup Olive oil & 2 cloves Garlic.
• 1 tbsp Fresh parsley, chopped.
• 1.5 tsp Red pepper flakes & 1 tsp Paprika.
• 3 tbsp Tomato sauce.

 Preparation Guide

1. Desalting: Soak the salted cod in cold water overnight. Change the water at least twice to remove excess salt.
2. Par-boiling: Boil the cod in a large pot for 5 minutes. Drain and allow to cool, then break into large chunks.
3. Layering: Preheat oven to 375°F (190°C). In an 8x11 dish, layer half the potatoes, all the cod chunks, and all the onions. Cover with the remaining potatoes.
4. The Sauce: Whisk together the olive oil, minced garlic, parsley, pepper flakes, paprika, and tomato sauce.
5. Baking: Pour the sauce evenly over the layers. Bake for 45 minutes until the potatoes are tender and golden.

 The Magic of Bacalhau

The success of a Portuguese Cod Fish Casserole hinges on the quality of the "desalting" process. Salted cod is remarkably different from fresh fish; the curing process transforms the texture, making it firmer and deeply flavorful. By soaking it, you rehydrate the fibers while leaving just the right amount of brine to season the entire casserole.

The Layering Technique ensures that the potatoes on the bottom absorb the seafood juices, while the onions in the middle caramelize slightly, providing a sweet counterpoint to the salty fish. The Garlic-Paprika Oil is the "liquid gold" of this recipe. It’s not just a sauce—it’s a poaching medium. As it seeps through the layers, the paprika provides a smoky depth and a vibrant red hue that makes the dish as beautiful as it is delicious. Serving this with a side of black olives or hard-boiled eggs is a common tradition that completes the authentic experience.

 Pro Tips for a Rustic Finish

Potato Slicing: Slice your potatoes to a medium thickness (about 1/4 inch). Too thin and they turn to mush; too thick and they won't cook through in 45 minutes.

Oil Quality: Since this recipe uses 3/4 cup of olive oil, use the best Extra Virgin Olive Oil you can find. It is the primary flavor carrier.

The Crust: For an extra-crispy top layer, brush the top potatoes with a little extra oil and broil for the last 3 minutes of cooking.
