Salmon Fillet
at 425°F
The answer
10 min – 15 minat 425°F
Salmon Fillets take about 10 min – 15 min in a 425°F oven. Done is 145°F on a food thermometer, plus a 3-minute rest — never the clock alone.

USDA safe zone — 145°F and above
Done is a temperature, not a time. Every figure on this page is a planning range; the green band is the only part that decides. For salmon fillets it opens at 145°F and a 3-minute rest.

How this is worked out
- Anchor. Start from what USDA FSIS publishes for salmon fillets — its safe minimum internal temperature of 145°F, and the FSIS roasting timetable where one exists for this cut.
- Rate. Convert the anchor into a planning rate at 425°F: a fixed published range, cross-checked against at least three independently published sources.
- Scale. This cut is timed by piece, not by weight, so the range is published as-is and widened to cover source disagreement rather than averaged.
- First check. The first thermometer reading is set at 85% of the low end of the range — early enough that an under-reading costs nothing and a late one cannot cost the meal.
- Gate. The time is only a plan. It is not done until a food thermometer reads 145°F in the thickest part, then rests about 3 minutes. Time never overrides temperature on this site.
- Round. Every printed figure is rounded to the nearest 5 minutes; precision beyond that would be invented.
plan_range = published range at 425°F
first_check = plan_low × 0.85
DONE ⟺ internal_temp ≥ 145°F AND rest ≥ 3 min
(USDA FSIS — the gate, not the clock)

When it is actually done
145°F internal
The USDA FSIS safe minimum internal temperature for this cut is 145°F, followed by a rest of about 3 minutes. The clock estimates; the thermometer decides. Every time on this page is a planning range, not a doneness test.
Sizing: Times are for typical 1–1.5 inch thick, 6–8 oz portions or a side of salmon of the same thickness — thickness, not weight, drives fish timing.

The clock tells you when to start looking. The thermometer tells you when to stop.
What the ledger does not tell you
- USDA's 145°F leaves salmon firm and fully opaque; many cooks pull at 125–130°F for a silkier medium — that is a personal-preference call below the federal guideline, made with fresh, well-handled fish.
- Fish flakes when pushed with a fork at done — the flake test and the thermometer usually agree within a minute.
- A whole side cooks in the same time as portions of the same thickness; it is one piece of the same geometry.
Answers people ask
How long does salmon fillets take at 425°F?
About 10 min – 15 min at 425°F (times are for typical 1–1.5 inch thick, 6–8 oz portions or a side of salmon of the same thickness — thickness, not weight, drives fish timing.). It is done at 145°F internal on a food thermometer, not by the clock.
What internal temperature is salmon fillets done at?
145°F, measured with a food thermometer in the thickest part, then rested about 3 minutes. That is the USDA FSIS safe minimum.
Is 425°F a good temperature for salmon fillets?
It is one of 3 temperatures this site publishes for this cut (375°F, 400°F, 425°F). Lower runs longer and more forgiving; higher runs faster with more browning. 400°F is the most common choice.

Where these numbers come from
Ranges are anchored to USDA FSIS published timetables where they exist, and derived from that anchor plus cross-checked published sources where they do not — widened to cover the disagreement between sources rather than split down the middle. The full reasoning is on the method page. If a figure here looks wrong, say so — corrections are prioritised.
