Preheat the oven to 450°F.
Remove the frozen fish from all packaging and rinse under cold running water to remove any ice crystals.
Arrange the salmon in a single layer on a rimmed baking sheet. Brush lightly with oil on all sides and sprinkle with salt, pepper, or any other seasonings.
Bake for 4-5 minutes. Remove from the oven and add any sauce.
Continue to bake until the salmon is hot and flaky in the center, 8-12 more minutes. (If your sauce is getting too brown, cover the salmon loosely with foil.) Thicker fillets may need a few extra minutes to cook through.
