How Long to Cook Salmon: Oven, Pan, and Air Fryer Times
Salmon is one of the most forgiving fish to cook — but it also goes from perfectly done to dry and chalky faster than almost anything else. The difference between great salmon and overcooked salmon is often just 2–3 minutes. Here are exact cook times for every method, plus the internal temperature that tells you it's actually done.
The Safe Internal Temperature for Salmon
The FDA recommends cooking salmon to an internal temperature of 145°F (63°C). At this temperature, the fish is fully cooked through, the flesh flakes easily, and it's safe for everyone including pregnant women and immunocompromised individuals.
Many cooks prefer salmon at 125–130°F (52–54°C) — medium, with a slightly translucent center that's still moist and silky. This is widely considered the best eating temperature for salmon but carries a small food safety risk. At 135–140°F (57–60°C), it's medium-well: fully opaque, still moist, and the safest middle ground.
Cook Times by Method
Oven-Baked Salmon (400°F / 200°C)
| Thickness | Cook Time | Result |
|---|---|---|
| ½ inch (thin fillet) | 8–10 min | Fully cooked |
| ¾ inch | 10–12 min | Fully cooked |
| 1 inch (standard) | 12–15 min | Fully cooked |
| 1¼ inch (thick) | 15–18 min | Fully cooked |
A useful rule of thumb for oven-baked salmon: 4–6 minutes per ½ inch of thickness at 400°F. Always check the thickest part of the fillet, not the thin tail end.
Pan-Seared Salmon (Medium-High Heat)
| Fillet Thickness | Skin Side Down | Flip & Finish |
|---|---|---|
| ¾ inch | 3–4 min | 1–2 min |
| 1 inch | 4–5 min | 2–3 min |
| 1¼ inch | 5–6 min | 2–3 min |
For pan-searing, cook skin-side down for most of the time — typically 70–80% of the total cook time. The skin acts as insulation and crisps up beautifully. Flip only once, just before the end.
Air Fryer Salmon (390°F / 200°C)
| Fillet Thickness | Cook Time |
|---|---|
| ¾ inch | 7–9 min |
| 1 inch | 9–11 min |
| 1¼ inch | 11–13 min |
Air fryer salmon doesn't need flipping. Place skin-side down, no need to preheat. The circulating air gives you a nicely browned exterior without added oil.
Poached Salmon (Gentle Simmer)
Bring your poaching liquid (water, broth, or court bouillon) to a bare simmer — not a full boil. Add the salmon, cover, and cook for 8–10 minutes per inch of thickness. Poached salmon should be just opaque through — it's done when it begins to flake but still holds together.
How to Tell When Salmon Is Done (Without a Thermometer)
The most reliable visual cue is opacity. Raw salmon is translucent and deep orange-pink. As it cooks, it turns opaque and lighter in color, starting from the outside and moving inward. For medium doneness, the center should still have a slightly darker, translucent strip.
For the fork test: insert a fork or thin knife into the thickest part at a 45-degree angle and twist gently. If the flesh flakes apart cleanly, it's done. If it resists and feels rubbery, give it another 2 minutes.
The white stuff that sometimes appears on the surface is albumin — a protein that's pushed out as the muscle fibers contract. It's completely safe to eat, but it's a sign the fish is cooking quickly or at high heat. It doesn't affect flavor.
Tips for Better Salmon Every Time
- Start with room-temperature fish. Cold salmon straight from the fridge takes longer and cooks unevenly. Pull it out 15–20 minutes before cooking.
- Pat it dry. Surface moisture creates steam instead of browning. Pat the fillet completely dry before pan-searing or air frying.
- Season right before cooking. Salt draws moisture to the surface. Season immediately before it hits the heat, or let it rest for 30+ minutes after salting (long enough for the moisture to reabsorb).
- Don't overcrowd the pan. Fillets need space for steam to escape. Work in batches if needed.
- Let it rest. Give salmon 2–3 minutes off the heat before serving. The internal temperature continues to rise slightly, and the juices redistribute.
Frequently Asked Questions
How long to cook salmon at 350°F?
At 350°F, salmon takes about 20–25 minutes for a 1-inch fillet — roughly 4–5 minutes longer than at 400°F. The lower temperature gives a gentler result with less risk of drying out the exterior before the center is done.
How long to cook frozen salmon?
You can cook salmon straight from frozen — add about 50% to the cook time. A 1-inch frozen fillet baked at 400°F takes approximately 18–22 minutes. Make sure it reaches the full 145°F internal temperature throughout.
How do you know if salmon is undercooked?
Undercooked salmon looks dark, translucent, and glossy in the center. It feels soft and almost raw when pressed. The flesh won't flake — it holds together in a slick, gelatinous way. If you see this, return it to heat immediately.
Can you eat salmon medium-rare?
Many people do, and it's delicious at 125–130°F with a slightly translucent center. The FDA recommends 145°F for food safety, particularly for pregnant women, elderly individuals, and anyone immunocompromised. For healthy adults, medium salmon is a widely accepted choice at restaurants and at home.
