When baking salmon (or any other fish, really), cooking time can vary widely.
A SIMPLE GUIDELINE:
For 8-oz filets, skin removed, try this. Preheat oven to 425°F and roast until the salmon is opaque, 16-18 minutes.
Adjust the cooking time depending on the size of your filets, but always check your fish frequently as it’s baking -- it’s not a dish you want to put in the oven and forget about.
