How Long to Bake Salmon at 350, 375, 400 and 425°F

A standard 1-inch salmon fillet bakes in about 20 to 25 minutes at 350°F, 12 to 15 minutes at 375°F or 400°F, and 8 to 12 minutes at 425°F. Thicker fillets need more time. Thin ones need less. Frozen fish takes much longer.

Every one of those numbers is a starting point, not a promise. The fish is done when the thickest part reaches 145°F, the FDA's safe minimum for fish. The sections below give you the time for each oven setting, explain what pushes it up or down, and show how to confirm doneness.

Salmon baking times at a glance

These times assume a fully preheated oven and a thawed fillet straight from the fridge. Start checking a couple of minutes before the low end of each range.

How long to bake salmon at 350°F

At 350°F, a 1-inch fillet takes about 20 to 25 minutes. A thin tail piece can finish well before that. A thick center cut close to 1½ inches can need about 30 minutes.

350°F is the gentlest of the four common settings. That is its main strength. The gap between done and overdone is wider here than at any hotter setting, so a small timing slip rarely ruins dinner. That makes it a good place for newer cooks to learn what done salmon looks like.

It also suits a sheet-pan meal. Potatoes, broccoli and asparagus need real oven time to cook through. At 350°F, the salmon and the vegetables are more likely to finish together.

A few other cases favor 350°F:

• Sweet glazes. Honey or teriyaki-style glazes have time to color without burning.
• Long marinades or brines. The gentle bake keeps those flavors front and center.
• Two proteins in one oven. Chicken or beef usually needs longer, so put the salmon in partway through the other protein's cook time. Do not start both at once.
• Meal prep batches. A wide margin lowers the risk of overcooking a whole week of portions in one bake.
• A whole side of salmon. The thin end finishes before the thick end, so check several spots along its length.

How long to bake salmon from frozen at 350°F

A standard fillet baked straight from the freezer at 350°F takes roughly 40 to 45 minutes. That is about double the thawed time, so start checking at the 30-minute mark.

The USDA says it is safe to cook food from frozen, and that it takes about 50 percent longer than cooking it thawed. Use that as your planning rule at any oven setting.

350°F is the best choice for frozen salmon. A hotter oven can overcook the outside while the center is still icy. The slower heat gives the middle time to catch up.

Use a thermometer here, not just your eyes. Color and flaking are harder to read on a fillet that started partly frozen. The same goes for a fillet that only looks thawed on the outside. If the center still feels icy, bake it at 350°F rather than 425°F.

How long to bake salmon at 375°F

At 375°F, a 1-inch fillet takes about 12 to 15 minutes. A fillet close to 1½ inches thick needs about 18 to 20 minutes.

375°F is the middle ground. It is faster than 350°F and does not need the close watch that 425°F demands. Many published recipes default to it for that reason. It is also a sensible pick if your recipe gives no temperature, or if you are turning a grilled or stovetop salmon recipe into a baked one.

A coated fillet bakes in about the same time as a plain one at 375°F. That includes a soy glaze, panko or a Parmesan crust. The coating is too thin to change how long the fish takes. It does change the visual cues, though. A browned, glossy top can look done before the fish under it is. Check with a thermometer, or pull back a bit of the coating to test for flaking.

Watch sugar-based glazes. Sugar can darken or burn before the fish is cooked through. If the glaze is browning fast partway through, loosely cover the fillet with foil.

How long to bake salmon at 400°F

At 400°F, a 1-inch fillet takes about 12 to 15 minutes. Some ovens finish the same fillet in 10 to 12 minutes. A thin fillet can be done in under 10 minutes. A thick center cut may need close to 18 minutes.

400°F is the setting most general salmon guidance lands on. It is quick enough for a weeknight. It still leaves a minute or two of slack before the fish dries out. That margin is narrower than at 350°F but wider than at 425°F.

You can still make a sheet-pan meal at 400°F if you size the vegetables to match. Asparagus spears and thin zucchini slices can finish in the same 12 to 15 minutes. Denser vegetables, like whole baby potatoes, need a head start of several minutes. Set vegetables around the edges of the pan, where hot air moves more freely.

Basting with butter or oil partway through helps a lean fillet hold moisture. Each time you open the door, though, the oven loses heat. That can add a minute or so to the bake.

How long to bake salmon at 425°F

At 425°F, a 1-inch fillet takes about 8 to 12 minutes. This is the fastest common setting. It also has the smallest margin for error. Sometimes only a minute or two separates done from dry, especially with a lean fillet.

The payoff is color. High heat browns the surface and crisps the edges before the inside overcooks. At 350°F you get much less of that effect.

425°F works best under these conditions:

• Salmon is the only thing on the pan. Most vegetables need far longer than 8 to 12 minutes.
• You can watch the oven. This is not a set-it-and-walk-away bake.
• You are using individual portions. Small, even pieces time more predictably than one large fillet cut up later.
• The fillet has some fat. A well-marbled piece handles fast heat better than a very lean one.

Broiling pushes this tradeoff even further. The heat comes from close above, so salmon can go from done to overcooked in less than a minute. Treat it as a faster method, not a gentler one.

What makes the same fillet bake faster or slower

Thickness matters more than any other factor. But several smaller details also shift the clock.

• Starting temperature. A fillet straight from the fridge needs a bit longer than one that sat out for a few minutes.
• Preheating. If you start the timer before the oven reaches temperature, the fish spends part of the bake in a cooler oven. This matters most at 400°F and 425°F, where the windows are short. Wait for the preheat signal, and give a slow oven a few extra minutes.
• Oven accuracy. Many home ovens run hotter or cooler than the dial says. An inexpensive oven thermometer on the rack shows the real number. If your salmon keeps finishing early or late, check this first.
• Convection. A fan oven cooks faster than a regular oven at the same setting. Many oven makers suggest lowering the temperature by about 25 degrees when using convection for a regular recipe.
• Pan and rack. A wire rack lets heat reach the underside, which can trim a few minutes. A glass or ceramic dish can add a little time. A dark metal pan browns the bottom faster than a light pan or parchment, which matters most at 425°F.
• Crowding. Leave space between fillets so air can move. Packed fillets trap moisture and brown less.
• Mixed sizes. Small portions finish before a large piece on the same pan. Pull each one as it is done.

Skin, foil and bone

Bake skin-on fillets skin side down. The skin shields the flesh from the hot pan, which buys a little extra margin at high heat. It also lets you lift the fish off and leave the skin behind. Skin side up is mainly for crisping the skin, often with a short broil at the end.

A skinless fillet sits right against the pan, so its bottom can cook faster. A greased pan, parchment or a wire rack gives it some protection.

Foil is optional at 350°F, where the margin is already wide. It helps more as the heat rises, and it helps most with lean or thin fillets. An open pan gives more color.

A salmon steak is a cross-cut piece with a section of backbone. The meat right around the bone takes a little longer to finish than the rest. Check near the bone, but not touching it.

How to check that baked salmon is done

Push an instant-read thermometer into the thickest part of the fillet. The FDA's safe minimum for fish is 145°F. Our salmon internal temperature guide covers what happens at readings above and below that point.

If you have no thermometer, look for these signs:

• The flesh separates easily with a fork, which is the FDA's own test for fish.
• The color turns from wet and see-through to matte and opaque.
• A few white beads of albumin appear on the surface.

Start checking a couple of minutes before the low end of the time range. Add a few minutes at a time if it needs more, then check again. Salmon can go from underdone to overdone fast.

If you open the oven often, you lose heat. A leave-in probe thermometer shows the temperature the whole time without opening the door. It is most useful at 425°F.

Let the fillet rest for 2 to 3 minutes after it comes out. Carryover heat finishes the last stretch, and the juices settle instead of running onto the plate.

Cook fully to 145°F or a little past it when serving young children, older adults or anyone at higher risk of foodborne illness. The safe minimum never moves. Where you aim above it can depend on who is at the table.

Thawing salmon and storing what is left

The FDA recommends thawing frozen seafood slowly in the refrigerator overnight. To thaw it faster, seal it in a plastic bag and put it in cold water. You can also use the microwave's defrost setting if you will cook the fish right away. Stop while the fish is still icy but bendable. Our guide on how long thawed salmon stays good in the fridge covers what to do if your plans change.

Store fresh salmon you will cook within 2 days in a refrigerator at 40°F or below. Otherwise, wrap it tightly and freeze it.

Once it is baked, do not leave salmon out for more than 2 hours. Cut that to 1 hour when it is above 90°F. Cooked fish keeps 3 to 4 days in the refrigerator. See how long cooked salmon lasts in the fridge for reheating and freezing tips.

For meal prep, cook the salmon toward the done end of its range. It will be reheated at least once, and reheating dries fish out further.

Salmon on the Red Lobster menu

If you would rather let someone else watch the oven, salmon shows up in several places on the Red Lobster menu. The Atlantic Salmon comes with a choice of two sides. The Sesame-Soy Salmon Bowl pairs soy-ginger-glazed grilled salmon with orzo rice, edamame and crispy Brussels sprouts. There is also a Classic Caesar Salad with Grilled Salmon and the Grilled Lobster, Shrimp and Salmon plate. You can browse the full dinner menu for the current lineup, or check calories for each dish on the nutrition page.

At home, the short version holds. Pick 350°F for a forgiving bake or frozen fish, 375°F or 400°F for an everyday weeknight fillet, and 425°F when you want crisp edges and can stand by the oven. Then trust the thermometer over the timer.
