Herb's take

Portugal’s iconic bacalhau gets a tinned twist by swapping cod for canned sardines, briny, bold, and seriously underrated. You’ll learn the trick to a crisp, flavorful breadcrumb topping and how to treat sardines with the reverence usually reserved for their cod cousins.

Instructions

  1. 01
    Preheat oven to 400°F. Lightly oil a 2-quart baking dish.
  2. 02
    Place the potato slices in a medium pot, cover with cold water, and add a generous pinch of salt. Bring to a simmer and cook for 8 minutes, until just tender but not falling apart. Drain and set aside.
  3. 03
    Heat 2 tablespoons olive oil in a large skillet over medium heat. Add the onion and cook until soft and golden, about 8 minutes. Stir in the garlic and cook 1 minute longer.
  4. 04
    Add drained tomatoes, bay leaf, and paprika to the skillet. Cook, stirring, until most of the liquid evaporates, about 6 minutes.
  5. 05
    Remove skillet from heat. Gently fold in the sardines, half the parsley, and lemon zest. Carefully break sardines into large chunks but don’t shred entirely.
  6. 06
    Arrange half the potatoes in a shingled layer in the baking dish. Top with half the sardine-tomato mixture. Repeat with remaining potatoes and sardine mixture.
  7. 07
    In a small bowl, whisk together eggs, milk, and half of the lemon juice with a pinch of salt and pepper. Pour evenly over the casserole.
  8. 08
    In another bowl, toss bread crumbs with remaining 1 tablespoon olive oil, thyme, and remaining parsley. Sprinkle over the casserole.
  9. 09
    Bake uncovered for 25–30 minutes, until bubbling and golden brown on top.
  10. 10
    Let rest 10 minutes before serving, then drizzle with a little extra lemon juice.
