Fish is a delicate meat and can be difficult to cook perfectly due to all the above factors. The cooking time also depends on if you’re baking, grilling, or frying it. To be considered cooked, you must reach the ideal salmon temperature which is 145°F.

With the chart below you can find the ideal cooking time for the exact size and weight of your salmon.

Important Notes

  • When baking salmon, it is important for it to reach the proper temperature. Cooking salmon to the proper temperature will ensure you kill off any bacteria on the food.

  • For salmon, the minimum cooking temperature is 145°F. The best way to check this temperature is with a cooking thermometer. It will measure the temperature in the middle of the fish, which is usually the last area to get hot.

  • As a general rule, salmon is cooked when the flesh pulls apart and is opaque in color.

How Long to Bake Salmon in an Oven At 350°F

The cooking times on these charts are based on a preheated oven temperature of 350°F. At this temperature, the salmon can reach 145°F inside without drying out. Keep in mind that cooking times may change based on these factors:

  • skinless or skin left on

  • frozen or fresh
You can cook salmon in foil or leave it uncovered. The temperature remains the same either way, so the foil doesn’t actually doesn’t have any effect on the cooking time.

Covering your salmon in foil will affect the browning though. That’s because the foil traps steam and keeps moisture inside. If you want crispy skin and some browning, leave the salmon uncovered.

When cooking fresh salmon at 350°F, bake 6 minutes for every 4oz. If you’re cooking frozen salmon, bake 9 minutes for every 4oz. So, if you’re cooking a whole 16 oz fresh fillet, you’ll need to bake it for about 24 minutes.

How Long to Air Fry Salmon At 350°F

You should always preheat your air fryer so it is hot enough to make food crispy. You can cook your salmon either fresh or frozen in the air fryer. Foil or parchment paper won’t affect the cooking, but it can make cleaning up easier.

You can air fry a fresh salmon fillet at 350°F for about 6-8 minutes. This cooking time is based on a 5-6 oz fillet. If your fillet is frozen, increase the time in the air fryer to 9-12 minutes.

How Long to Grill Salmon At 350°F

Grilling is a great way to get a nice sear when you cook your salmon. This charred smokiness also adds some nice flavor. If you’re grilling salmon, skip the foil so the skin can get nice and crispy.

Cook a fresh 6 oz salmon fillet for 6 minutes on a 350°F grill. That equals 3 minutes on each side. Beware that salmon cooks very fast on the grill, so watch it closely.

If you’re cooking a 16oz or bigger fillet, you’ll need to cut it into 4 portions. Otherwise, the salmon won’t cook all the way through. Cooking time will vary depending on the thickness of the fillet.
