Cooking fish al cartoccio—literally, “in a bag”—is a technique that’s been used by Italians (and other cultures) for a long time. It’s actually a method of steaming rather than baking; the tight wrapping seals in all the juices and aromas so you end up with a mouthwatering combination of flavors. Traditionally, the fish is wrapped in parchment paper, but I like to use aluminum foil because it’s easier to close tightly. (It’s not as pretty or traditional as parchment paper, but aluminum foil is one modern convenience that I’m just not willing to forgo for the sake of prettiness or tradition.) You can cook almost any fish you want in foil or parchment, and indeed in Italy it’s usually used for swordfish and sea bass, not salmon, which doesn’t swim in the Mediterranean; but I love salmon’s creaminess and year-round availability, so I’ve taken my liberties with the al cartoccio tradition. This method also produces superb vegetables and chicken. And a bonus: It’s mess-free.

Ingredients
Preparation
Step 1
Preheat the oven to 400 degrees F. In a medium bowl, stir the tomatoes, shallots, 2 tablespoons of oil, lemon juice, oregano, thyme, 1/2 teaspoon of salt, and 1/4 teaspoon of pepper. In the center of each of four large sheets of aluminum foil, spoon 1/2 teaspoon of oil. Place 1 salmon fillet atop each sheet of foil and turn to coat with the oil. Sprinkle the salmon fillets with the remaining 1/2 teaspoon each of salt and pepper. Spoon the tomato mixture over the salmon. Fold the sides of the foil over the fish and tomato mixture, covering completely, and seal the packets closed. Place the foil packets on a large, heavy baking sheet. (The salmon packets can be prepared up to this point 6 hours ahead. Refrigerate until ready to bake.)
Step 2
Bake until the salmon is just cooked through, about 25 minutes. Using a large metal spatula, transfer the foil packets to plates and serve. (You may want to unwrap and plate the fish in the kitchen before serving.)
