Olive oil for the foil
Four 5- to 6-ounce skinless salmon fillets
Kosher salt and freshly ground black pepper
1 tablespoon unsalted butter; cut into 4 pieces
1 tablespoon chopped fresh dill and/or parsley
Half a lemon
Position an oven rack in the top of the oven, and preheat to 450 degrees F. Line a rimmed baking sheet with foil, and brush with oil.
Place the salmon fillets, evenly spaced, in the middle of the prepared baking sheet. Sprinkle the tops with 3/4 teaspoon salt and a few grinds of pepper. Bake until the outside is opaque and slightly firm to the touch and the inside flakes easily (insert a small paring knife between layers to check; the color will vary from bright pink (rare) to pale pink to orange (well-done)), 8 to 12 minutes, depending on the desired doneness.
Remove the fillets from the oven, top each with a piece of butter and let melt over the top and down the sides. Sprinkle with herbs, lemon juice and salt to taste. Transfer the salmon to serving plates with a spatula. Serve hot or at room temperature.
