Preheat the oven to 300 degrees. Fill a roasting pan with boiling water and place it on the floor of the oven.
Remove any visible bones from the salmon fillet using tweezers. Salt and pepper the fish generously. Place on a lightly oiled baking sheet.
Place in the oven and bake until the fish flakes, about 15 to 20 minutes. If the fillet is not very thick, check after 10 minutes. The fish should pull apart with a fork but should still look (and be) moist.
Transfer to a platter, using spatulas, and serve hot, at once, or allow to cool and serve at room temperature or chilled.
