Baking salmon at 400°F (200°C) is one of the most commonly used ways to prepare this delicious and nutritious fish the way you like it. At this temperature you get a crispy outer layer while keeping the salmon moist and flaky inside.
Salmon is considered ‘fully’ cooked when it is 145 degrees Fahrenheit or 63 degrees Celsius at its most thickest, internal part of the fish.

How long to bake salmon at 400°F (200°C)? Instructions:
Preheat the Oven to 400°F (200°C) then prepare the Salmon. Place the salmon fillets, steaks, or whole fish on a lined baking sheet or in a baking dish.
You may season the salmon with your choice of ingredients such as olive oil, lemon juice, garlic, herbs (like dill or parsley), salt, and pepper.

Now bake the Salmon: Put the salmon in the preheated oven and set a timer based on the thickness of the fish. A thinner fillet may only need 12 minutes, while a thicker steak could require up to 20 minutes.
The baked Salmon is done when it flakes easily with a fork. If you have a thermometer, check the thickest part of the salmon for an internal temperature of 145°F (63°C).
Remove the salmon from the oven and let it rest for a minute or two before serving. This allows the juices to settle, keeping the fish moist and flavorful.
