For every 1/2 inch, bake a salmon 4 to 6 minutes at 450 degrees Fahrenheit. The salmon is cooked through when it becomes flaky and opaque. White juices on the baking dish are another signal that the salmon is cooked.
Salmon can be baked at 350 degrees Fahrenheit for roughly 7 minutes for every 8-ounce fillet. Lower temperatures and longer cooking times are ideal for dressed salmon fillets to ensure that the fish is cooked through before serving it.
Salmon fillets can be wrapped in foil with seasonings and baked at 350 degrees Fahrenheit for 30 minutes. Every 4-ounce salmon fillet should be individually wrapped and placed inside a baking dish to catch leaking juices.
