You're standing in the kitchen with a gorgeous piece of Atlantic salmon, and you're paralyzed. The internet is screaming at you. One blog says 350°F for a slow roast, while a celebrity chef insists on a 425°F blast to get that "perfect" crust. It’s frustrating. Honestly, figuring out what temp to bake salmon in oven shouldn't feel like a high-stakes chemistry final.
Most people overcook salmon. They wait until it's opaque all the way through, which usually means the proteins have tightened up so much they’ve squeezed out all the moisture. You know that white stuff that seeps out of the fish? That’s albumin. It's totally safe to eat, but it's a giant red flag that your heat is too high or your cook time is too long. If your salmon looks like it’s wearing a white sweater, you’ve probably gone too far.
The 400°F Sweet Spot (And Why It Works)
If you want the short answer, 400°F (204°C) is the gold standard for a reason. At this temperature, the exterior of the fish gets a nice, slight sear while the middle stays succulent. It’s fast. You aren't sitting around for forty minutes waiting for dinner. Usually, a standard-sized fillet takes about 12 to 15 minutes at this heat.
But wait. There’s a catch.
The thickness of your fish matters more than the clock. A wild-caught Sockeye fillet is much thinner and leaner than a farm-raised King salmon. If you treat them the same, the Sockeye will turn into jerky before the King is even warm. You've got to look at the "shoulder" of the fish—that thickest part in the middle.
Some folks swear by the "Low and Slow" method. J. Kenji López-Alt, a guy who basically turned kitchen science into a religion, often advocates for temperatures as low as 225°F or 250°F. Why? Because it prevents the muscle fibers from contracting violently. The result is a texture that’s almost like butter. It’s incredible, but it takes forever, and you won’t get any crispy skin. Most of us on a Tuesday night just want dinner on the table.

Deciding What Temp to Bake Salmon in Oven Based on Your Goal
Texture is subjective. Some people like their salmon firm and flaky; others want it nearly translucent in the center, sushi-style.
For a Crispy Skin and Flaky Meat, go with 425°F. You need that high heat to render the fat in the skin quickly. Make sure the skin is bone-dry before it hits the pan or the parchment paper. Moisture is the enemy of crispiness. If the skin is wet, it just steams. Gross.
For Reliable, Everyday Salmon, stick to 400°F. It's the "set it and forget it" (mostly) temp. It works for sheet pan dinners where you have asparagus or broccoli roasting right alongside the fish. Most vegetables roast beautifully at 400°F, making it the most efficient choice for a complete meal.
For Ultra-Tender, "Confit" Style Salmon, drop it to 275°F. This is for when you have a high-quality piece of fish and you want to impress someone. It’ll take about 25 to 30 minutes. The fish will stay a deep pink color even when it’s fully cooked. It’s a bit of a mind-game because we’re trained to think pink means raw, but at this temp, it’s just gently poached in its own fats.
Does the Oven Mode Matter?
Yes. If you have a convection setting, use it, but drop the temperature by about 25 degrees. Convection blows hot air around, which speeds up evaporation and cooking. If you're wondering what temp to bake salmon in oven on convection, 375°F is your target.

The Internal Temp is the Real Boss
Forget the timer for a second. If you want to cook like a pro, buy a digital instant-read thermometer. It’s the only way to be 100% sure.
The USDA recommends 145°F. Honestly? That's too high for most people. At 145°F, salmon is well-done and can be quite dry. Most chefs and seafood experts suggest pulling the salmon out of the oven when it hits 125°F to 130°F for medium-rare, or 135°F for medium.
Carryover cooking is a real thing. Once you take the fish out, the internal temperature will continue to rise by another 5 degrees while it rests. Give it three minutes of peace on the counter before you flake it.
- 120°F: Rare (Very soft, translucent)
- 125°F - 130°F: Medium-Rare (The "Chef's Choice")
- 135°F - 140°F: Medium (Firm, but still moist)
- 145°F+: Well-Done (Dry, chalky, lots of white albumin)
Mistakes You’re Probably Making (I’ve Done Them Too)
Putting cold fish in a hot oven is a recipe for uneven cooking. The outside gets hammered by the heat while the inside stays icy. Take the salmon out of the fridge about 15 to 20 minutes before you plan to bake it. Let it take the chill off.
Another big one: not seasoning enough. Salmon is a fatty, rich fish. It can handle a lot of salt. If you're just doing a tiny pinch, you're missing out. Salt doesn't just add flavor; it helps break down the proteins so the fish stays tender.

And please, stop over-handling it. Put it in the oven and leave it alone. You don't need to flip it. You don't need to baste it every two minutes. Let the ambient heat do the work.
How to Tell It's Done Without a Thermometer
If you don't have a thermometer, use the "fork test," but do it gently. Press down on the top of the fillet with a fork or your finger. If the flakes of the fish begin to separate easily along those white lines (the fat), it's done.
Another old-school trick is the metal skewer method. Poke a thin metal skewer into the thickest part of the salmon, hold it there for three seconds, and then touch it to your bottom lip. If it’s cold, it’s raw. If it’s warm (like bathwater), it’s perfect. If it’s hot, you’ve overcooked it.
The Foil Question
Should you wrap it?
Baking salmon in foil (en papillote) is a different beast. Because the foil traps steam, the temperature is less about searing and more about poaching. If you're using foil, 375°F is usually better. It creates a little mini-sauna for the fish. It's almost impossible to dry out salmon in foil, but you will completely sacrifice any chance of crispy skin. It’s a trade-off.
If you’re doing a sheet pan meal with thin stalks of asparagus, 400°F works perfectly without foil. If you’re doing thicker root vegetables like potatoes, you’ll need to start the potatoes 20 minutes before you even think about putting the salmon in the oven.
Actionable Steps for Your Next Dinner
- Remove the salmon from the fridge 20 minutes before cooking to reach room temperature.
- Pat the skin dry with paper towels. Seriously, get it as dry as possible.
- Preheat your oven to 400°F. Ensure the rack is in the middle position.
- Season aggressively with kosher salt, black pepper, and maybe a little garlic powder or lemon zest.
- Place skin-side down on a parchment-lined baking sheet.
- Bake for 12-14 minutes. Start checking the internal temperature at the 10-minute mark.
- Pull at 135°F for a perfect medium flake.
- Rest for 3 minutes. This allows the juices to redistribute so they don't all run out the second you hit it with a fork.
Cooking salmon perfectly is really just about managing the relationship between time and heat. Start with 400°F. It’s the most forgiving, effective, and versatile temperature for almost any cut of fish you’ll find at the grocery store. Once you master that, you can start playing with the "low and slow" methods or the high-heat broil finishes, but for tonight? 400°F is your best friend.
