How Long to Cook Salmon at 400


If you’re preparing salmon, there are several questions that come to mind. How long should I cook it? What temperature? And is 40 minutes too long? In this article, we’ll answer all those questions and more!

15 minutes

Preheat the oven to 400 degrees. Place a piece of foil on a baking sheet, then place the salmon on top of it. Sprinkle with salt and pepper, if desired. Bake for 15 minutes or until cooked through (the internal temperature should reach 145 F).

25 minutes

If you’re cooking salmon for the first time and want to make sure it’s done right, try this simple test:

If you can easily flake the fish with a fork, then it’s ready!

35 minutes

  • Cooking time depends on thickness. The thicker the salmon, the longer it will take to cook through. A good starting point is 35 minutes at 400 degrees F (204 C). You can increase or decrease this time depending on your preference for doneness and opacity of flesh.
  • Use a thermometer to check for doneness. Inserting an instant-read thermometer into the thickest part of your fillet is not only easier than cutting into it with a knife; it also ensures that you’ll get perfectly cooked fish every time!

40 minutes

Cooking time will depend on the thickness of your salmon fillet. For example, a 1-inch thick piece of salmon should cook for about 40 minutes at 400 degrees Fahrenheit. You can also use a meat thermometer to check if your fish is done; when it reaches an internal temperature of 145 degrees Fahrenheit (65 degrees Celsius), it’s ready to eat!


Salmon can be cooked at 400 degrees for 15, 25, 35 and even 40 minutes.

The minimum cooking time for salmon at 400 degrees is 15 minutes. The maximum is 40 minutes, although this would produce a very well-done piece of fish that may not be appealing to everyone. It’s best to cook it somewhere between 25 and 35 minutes for flaky, pink fillets.


In conclusion, it’s safe to say that you can cook salmon at 400 degrees for 15, 25, 35 and even 40 minutes. The length of time depends on how well done you prefer your fish and whether or not it is frozen before cooking begins.
