Baking salmon is the most forgiving way to cook fish. No oil splattering, no watching the pan — just season it, put it in the oven, and pull it out in 12 to 15 minutes. The result is tender, flaky salmon with a slightly caramelized top that beats most restaurant versions.
This guide covers everything: the right temperature, exact timing for different thicknesses, the best seasonings, how to tell when it’s perfectly done, and five baked salmon recipes that people make every week.
| Temperature | 1-inch fillet | 1.5-inch fillet | Result |
|---|---|---|---|
| 375°F (190°C) | 15–18 min | 20–25 min | Gentle, very moist |
| 400°F (200°C) | 12–15 min | 15–18 min | Best balance — flaky + slightly caramelized |
| 425°F (220°C) | 8–10 min | 12–14 min | Faster, slightly firmer exterior |
Bake salmon at 400°F for 12–15 minutes, or until it reaches 145°F (63°C) internally. This is the sweet spot for most home cooks — fast enough to be weeknight-ready, gentle enough to stay moist.
Baked Salmon Basics: Temperature and Time
The single biggest mistake when baking salmon is overcooking it. Overcooked salmon turns dry, chalky, and dull-tasting. Perfectly baked salmon is translucent pink in the center, pulls apart in clean flakes, and melts on the tongue.
Two things determine doneness: oven temperature and fillet thickness. The time recommendations above assume a 1-inch to 1.5-inch fillet, which is standard for most salmon portions you’ll buy at the grocery store. Thinner fillets (under 3/4 inch) cook faster — check at 8 minutes.
Internal temperature is the most reliable method. Pull salmon from the oven when the thickest part reads 125–130°F (52–54°C) for medium-rare, or 145°F (63°C) for fully cooked. USDA/FDA guidance recommends 145°F, but many cooks and chefs prefer 130°F for a silkier texture.
The Method
How to Bake Salmon — Step by Step
Preheat your oven to 400°F (200°C)
Give the oven at least 15 minutes to fully preheat. A fully preheated oven means the salmon starts cooking immediately from all directions — not just from the bottom. This is what gives you even cooking and that slightly caramelized top.
Pat the salmon dry
Use paper towels to pat the salmon fillets completely dry. Moisture on the surface creates steam, which prevents browning and dilutes the seasoning. Dry fish = better flavor and better texture.
Season generously
Brush with olive oil or butter, then season with salt, black pepper, and your chosen seasoning (see the seasoning section below). Don’t be shy with salt — salmon is a thick protein and needs enough seasoning to flavor it through to the center.
Place on a lined baking sheet, skin-side down
Line a baking sheet with parchment paper or foil. Place fillets skin-side down — the skin acts as a natural barrier that protects the flesh from the direct heat of the pan, resulting in more even cooking. You can also bake in a baking dish if that’s what you have.
Bake 12–15 minutes
For a standard 1-inch fillet at 400°F, bake 12 minutes for medium-rare or 15 minutes for fully cooked. Do not open the oven during cooking — temperature drops slow the cooking and affect texture.
Rest for 2 minutes, then serve
Let the salmon rest on the pan for 2 minutes after removing from the oven. This allows the juices to redistribute and the residual heat to finish any remaining cooking. Serve immediately — baked salmon is best fresh from the oven.
Most Common Method
How Long to Bake Salmon at 400°F
400°F is the best temperature for baking salmon. It’s hot enough to develop a slightly golden exterior and cook through quickly, but not so hot that the outside dries out before the inside is done.
| Fillet Thickness | Medium-Rare (130°F) | Fully Cooked (145°F) |
|---|---|---|
| Thin — under 3/4 inch | 8 min | 10 min |
| Standard — 1 inch (most fillets) | 12 min | 14–15 min |
| Thick — 1.5 inches | 15 min | 18 min |
| Very thick — 2 inches | 18 min | 22 min |
When baking multiple fillets, leave at least 1 inch of space between them on the pan. Crowded fillets trap steam and cook unevenly — they steam instead of roast and won’t get that slightly caramelized surface.
Gentler Method
How Long to Bake Salmon at 375°F
375°F is the gentler option. It produces very moist, silky salmon — less caramelization on the outside, but even more tender through the center. Use 375°F when baking salmon in a sauce, marinade, or foil packet that would burn or over-reduce at a higher temperature.
| Fillet Thickness | Medium-Rare (130°F) | Fully Cooked (145°F) |
|---|---|---|
| Thin — under 3/4 inch | 10 min | 13 min |
| Standard — 1 inch | 15 min | 18 min |
| Thick — 1.5 inches | 20 min | 25 min |
Flavor
Best Seasonings for Baked Salmon
Salmon has a rich, naturally buttery flavor that pairs well with both bold and subtle seasonings. These are the combinations that work every time:
Classic
Garlic Butter
Melted butter, minced garlic, lemon juice, fresh parsley. The most popular baked salmon seasoning — rich, savory, and universally loved.
Sweet & Savory
Honey Garlic
Honey, soy sauce, garlic, a splash of lemon. The glaze caramelizes beautifully in the oven — sticky, shiny, and deeply flavorful.
Bold
Cajun Spice
Paprika, cayenne, garlic powder, onion powder, black pepper, dried thyme. Bold, smoky, and spicy — the seasoning that makes salmon feel like restaurant food.
Mediterranean
Lemon Herb
Lemon zest, olive oil, garlic, fresh dill or parsley, capers. Clean, bright, and light — the classic Mediterranean approach to baked salmon.
Asian
Teriyaki Glaze
Soy sauce, rice vinegar, brown sugar. Brush on before baking and again halfway through. The result is lacquered, glossy salmon with a deep umami flavor.
Dijon
Dijon & Brown Sugar
Dijon mustard, brown sugar, garlic, a pinch of cayenne. The tangy-sweet crust that forms on top is one of the best textures baked salmon can have.

5 Best Baked Salmon Recipes
1. Garlic Butter Baked Salmon
15 minutes total Most popular
The classic. Salmon fillets brushed with garlic butter, baked at 400°F for 12–15 minutes, finished with a squeeze of fresh lemon and chopped parsley. This is the recipe most people make first and keep making forever. The garlic butter soaks into the flesh as it bakes, producing salmon that is simultaneously light and deeply savory.
What makes it work: use real butter (not spray), mince the garlic fine so it infuses without burning, and finish with lemon right before serving so the brightness is fresh rather than baked-in and muted.

2. Honey Garlic Baked Salmon
20 minutes total
A glaze of honey, soy sauce, garlic, and lemon juice brushed on the salmon before baking. The honey caramelizes in the oven, forming a sticky, shiny glaze with a slight char around the edges. This is the baked salmon recipe for people who think they don’t like fish — the honey-soy glaze is sweet enough to convert anyone.
Technique: brush on half the glaze before baking, then brush the remaining glaze during the last 3 minutes for a double-layered coating that doesn’t burn.

3. Baked Salmon in Foil
20 minutes total Zero cleanup
Salmon, lemon slices, fresh dill, and butter wrapped in foil and baked at 375°F until the fish steams inside its own packet. Foil-baking is the most forgiving method — the steam inside the packet keeps the salmon moist even if you slightly overcook it. And cleanup is folding up the foil and throwing it away.
The catch: foil baking doesn’t give you the caramelized top that open baking does. The trade-off is moisture and ease vs. that slightly browned surface. Both are good; this one is more forgiving.
4. Teriyaki Baked Salmon
20 minutes + marinating
Salmon marinated for 30 minutes (or up to 4 hours) in a teriyaki sauce of soy, rice vinegar, and brown sugar, then baked at 400°F. The marinade both flavors the fish and forms a lacquered glaze as it bakes. Serve over white rice with steamed broccoli and sesame seeds — this is the baked salmon dinner that competes with any Asian restaurant.
5. Cajun Baked Salmon
15 minutes total Bold flavor
Salmon coated in homemade Cajun seasoning (paprika, cayenne, garlic powder, onion powder, black pepper, dried thyme, dried oregano) and baked at 400°F. The spice crust forms on the outside while the inside stays tender and moist. Serve with a simple creamy sauce (Greek yogurt + lemon + garlic) to cut the heat. The most impressive-tasting baked salmon for the least effort.

How to Tell When Salmon Is Done
The most reliable way to check baked salmon is a fork and a thermometer. Here’s how to use each:
Fork test: press the thickest part of the fillet with a fork and twist gently. If the salmon flakes easily and the flesh separates into clean, opaque segments, it’s done. If it resists flaking or looks translucent and glossy in the center, give it 2 more minutes.
Thermometer: insert an instant-read thermometer into the thickest part. 125–130°F (52–54°C) = medium-rare (pink, silky center). 145°F (63°C) = fully cooked (opaque throughout, flaky). Anything over 150°F = overcooked (beginning to dry out).
What to avoid: white albumin (the white liquid that oozes out of salmon as it cooks) is a sign you’re pushing toward overdone. A little is normal; if it’s pooling heavily, pull the salmon off the heat immediately.
Salmon continues cooking for 1–2 minutes after you pull it from the oven. If you want the internal temperature to reach 145°F, pull it at 142°F. If you want medium-rare (130°F), pull it at 127–128°F.
| Doneness | Internal Temp | What It Looks Like |
|---|---|---|
| Medium-Rare | 125–130°F (52–54°C) | Translucent pink center, very silky |
| Medium (Recommended) | 135–140°F (57–60°C) | Barely pink center, very moist and flaky |
| Well Done (USDA) | 145°F (63°C) | Opaque throughout, flaky, slightly firmer |
| Overcooked | 160°F+ (71°C+) | Dry, chalky, white albumin pooling |
Frequently Asked Questions
How long to bake salmon at 400°F?
For a standard 1-inch salmon fillet at 400°F: 12 minutes for medium-rare (130°F internal) or 14–15 minutes for fully cooked (145°F internal). Thinner fillets (3/4 inch) are done in 10 minutes. Thick fillets (1.5 inch) need 15–18 minutes. Always check with a thermometer rather than relying on time alone.
Should I bake salmon covered or uncovered?
Uncovered for most recipes — this allows the surface to caramelize and any glaze to set and concentrate. Cover with foil only if you’re baking in a sauce or marinade that might burn, or if you specifically want the foil-packet steaming method for maximum moisture.
Do I need to flip salmon when baking?
No. Bake salmon skin-side down the entire time. The skin acts as a protective layer that keeps the bottom of the fillet from drying out while the top cooks. You don’t need to flip it and shouldn’t — flipping risks breaking the fillet and losing the skin’s protective benefit.
Can I bake frozen salmon without thawing?
Yes. Rinse the salmon under cold water to remove ice crystals, pat dry, season, and bake at 400°F. Add 5–7 minutes to the cooking time — a 1-inch fillet will take about 18–20 minutes from frozen. Check with a thermometer for doneness rather than relying on visual cues, since frozen salmon can look done on the outside while still being undercooked in the center.
What temperature is salmon done at?
The USDA recommends 145°F (63°C) for fully cooked salmon. Most home cooks and chefs prefer to pull salmon at 130–135°F for a medium texture — silky, moist, and flaky with a slightly translucent center. Either is safe; the choice is about texture preference.
How do I know when salmon is done baking without a thermometer?
Use the fork test: press the thickest part with a fork and twist slightly. If the flesh flakes into clean, opaque segments and pulls away from the skin easily, it’s done. If it resists and looks glossy or translucent at the center, return it to the oven for 2 more minutes. The color changes from deep pink (raw) to a lighter, more opaque pink as it cooks.

The Bottom Line
The secret to perfect baked salmon is not overcooking it. 400°F for 12–15 minutes is your baseline — adjust for thickness, check with a thermometer, and pull it off heat a few degrees early since carryover cooking does the rest.
Start with garlic butter. It’s the simplest, most universally loved version. Once you’ve made that twice, try the honey garlic glaze for something sweet, or the Cajun spice rub when you want bold flavor. All three work every time.
