What Impacts How Long Salmon Cooks in the Oven?
There are a few key factors that affect total cook time when baking salmon fillets:
Thickness – Thicker cuts of salmon take longer to cook through to the center. Aim for evenly sized fillets around 1 inch thick.
Temperature – 350°F is on the lower end for fish baking. Higher oven temps will decrease cooking time.
Quantity – Baking multiple fillets together slightly increases time. Leave space between portions.
Additions – Toppings like glazes or stuffings may require extra time to finish cooking
Oven differences – All ovens vary slightly in how they hold set temps. Get to know your appliance.
What Is the Recommended Internal Temperature for Salmon?
It’s important not to undercook salmon due to food safety risks. But you also want to avoid overcooking, which makes the fish dry and flavorless.
Use an instant read thermometer to check the thickest part of the fillet. Salmon should reach an internal temperature of at least 145°F.
For reference, the FDA recommends:
- 145°F for medium rare
- 160°F for medium
- 170°F+ for well done
Visually, the salmon should flake easily with a fork when it’s done cooking.
How Long to Bake Salmon at 350°F Based on Thickness
Here are general guidelines for how long to bake salmon fillets at 350 degrees Fahrenheit:
- 1-inch thick: 20 to 25 minutes
- 1 1⁄2-inches thick: 25 to 30 minutes
- 2-inches thick: 30 to 35 minutes
Remember, these times are just estimates. Rely on a food thermometer for accuracy.

Frequently Asked Questions
Should I bake salmon with or without skin?
This is personal preference. Skin-on retains moisture as it cooks. Skinless allows seasonings direct contact. Both work well!
What if my salmon is undercooked or overcooked?
If undercooked, return to the oven for a few more minutes. If overcooked, reduce time next attempt and pull it sooner.
Can I foil wrap salmon while baking?
Yes, wrapping in foil helps steam and retain moisture. Add seasonings inside pouch.
Should I flip the salmon halfway through baking?
Flipping promotes even cooking, but isn’t required if presentation is important.
Can I bake frozen salmon fillets?
Yes, thaw first in fridge overnight. Pat dry before seasoning and baking as usual. May take slightly longer.
How do I know if my salmon has gone bad?
Signs of spoiled salmon include an off-putting fishy smell, slimy texture and dull or grayish color. When in doubt, throw it out!

How long to bake salmon
According to U.S. Food Safety guidelines, salmon should be cooked to an internal temperature of 145 degrees, or until the flesh does not appear translucent and can be easily separated with a fork.
Using a food thermometer is the best way to ensure your salmon is thoroughly cooked.
Here’s how long to cook your salmon based on oven temperature, according to the Alaskan Salmon Company:
- 350 degrees: 12-15 minutes per inch of thickness
- 375 degrees: 10-12 minutes per inch of thickness
- 400 degrees: 8-10 minutes per inch of thickness
- 425 degrees: 6–8 minutes per inch of thickness
- 450 degrees: 5-7 minutes per inch of thickness
How to bake salmon
Overcooking is the downfall of any baked salmon. Using a food thermometer and monitoring the temperature of the fish can help prevent this, but there are a few other things to keep in mind.
First, you’ll want to set your oven to the desired temperature – a lower temperature, like 375 degrees, is recommended because it helps the salmon cook evenly. Cover the salmon in a bit of oil and the seasonings of your choice and place it skin-side down on a baking sheet.
Next, watch the color as it turns light pink and the fish goes from translucent to opaque. Using a timer, a thermometer and your own eyes guarantees a perfectly cooked salmon.
You can also pull the salmon out a few minutes before its done (around 120 degrees or so, according to Bon Appetit) and let it rest for 5-10 minutes. The leftover heat will continue to cook the salmon and prevent overcooked, dry fish.
Another method is to try the “flake test” by using your fork to gently press against the fish. If the salmon separates into “flakes” smoothly and without much resistance, your fish is done.
