Cod en Papillote (Merluzzo al Cartoccio) – Easy Italian Baked Fish
This Italian Cod en Papillote, or Merluzzo al Cartoccio, combines flaky cod fillets with zucchini, tomatoes, red onion, black olives, lemon, and fresh thyme. This is an easy Italian fish recipe where the cod gently steams in its own juices, creating a light, healthy, and flavor-packed meal with minimal cleanup.
Preheat oven to 400°F (200°C). Cut four large sheets of parchment paper.
Place zucchini the center of each sheet. Place a cod fillet on top. Add tomatoes, onions. Season lightly with salt and pepper. Add olives, lemon slices, and a sprig of thyme. Drizzle generously with olive oil.
Fold the parchment over the fish and crimp the edges tightly to create a sealed packet.
Place packets on a baking sheet. Bake for 15–18 minutes, depending on the thickness of the fish.
Transfer packets to plates and open carefully at the table.Finish with an extra drizzle of olive oil and fresh lemon juice.
