Sauté onions in olive oil until golden and caramelized. Add garlic and cook until fragrant.
Make the béchamel sauce by melting butter, whisking in flour, and slowly adding milk until smooth and creamy. Season with salt, pepper, and a touch of nutmeg.
In a baking dish, layer thinly sliced potatoes, cubed potatoes, caramelized onions, sliced tomato, black olives, dried oregano, fresh thyme, shredded cod, and cod chunks.



Pour the béchamel sauce evenly over the layers.

Bake at 375°F until golden and bubbling.
Let cool completely before removing from the pan—or bake and serve straight from a Pyrex dish.
For extra flavor, marinate the cod in olive oil, garlic, and herbs before cooking.
Use a mandoline slicer for evenly thin potato slices.
