Remove the salmon from the refrigerator 30 minutes before cooking to bring it to room temperature. Preheat the oven to 250 degrees and place a shallow pan of water on the bottom rack.

Finely grate the zest of the lemon until you have 1 teaspoon.  Combine the lemon zest, shallots, dill, tarragon, and parsley in a small bowl, and stir in 2 tablespoons olive oil.

Place the salmon, skin side down, on a baking sheet and season with 2 teaspoons kosher salt and some freshly ground black pepper.  Smear about a third of the herb mixture on the fish and turn it over.  Slather the skin side of the fish with the remaining herb mixture and season with a little more salt and pepper.

Place the salmon on a wire rack set on a baking sheet, or in a roasting pan.  Bake the salmon about 25 minutes, until medium rare, or medium. To check if the salmon is done, peek between the flakes.  If it doesn’t separate into flakes, it’s not ready yet.
