You’ll usually bake salmon for about 10–20 minutes in a hot oven, depending mainly on thickness and oven temperature.

Quick Scoop

  • A common rule: 4–5 minutes per ½ inch of thickness at 375–400°F (190–200°C).
  • Most salmon fillets are done in 12–20 minutes at 375–400°F.
  • A larger side (around 2 pounds) often takes 15–20 minutes at 375°F.
  • Salmon is done when it flakes easily with a fork and looks opaque, with juices just turning milky.

Typical Oven Times

  • 375°F (190°C), fillet or side: about 15–20 minutes , depending on thickness.
  • 400°F (200°C), fillets: about 12–20 minutes (start checking at 12 minutes).
  • 450°F (230°C), fillets or pieces: about 10–15 minutes.

Simple example

If your salmon is about 1 inch thick at the thickest part, baking at 375–400°F usually means checking for doneness around 12–15 minutes and pulling it when it flakes but is still moist.

TL;DR: Preheat to 375–400°F, bake salmon for roughly 4–5 minutes per ½ inch of thickness, and start checking around 12 minutes so you don’t overcook it.
