Baking Salmon in the Oven: 180°C Temp & Time Guide

Few things disappoint at dinner like a piece of salmon that looked perfect in the pan but turned out dry and chalky. The good news is that oven baking gives you more control than frying — as long as you respect two numbers: 180°C and 15 minutes. This guide pulls the cooking times and temperatures that repeat across France’s most-trusted recipe sites so you get juicy salmon every time.

Ideal Oven Temperature: 180°C · Cooking Time for Pavé: 10-15 minutes · Thickness-Based Time: 10 min per 2-2.5 cm · Max Time to Avoid Dryness: 15 minutes

What temperature to cook salmon?

The most consistent recommendation across French recipe sites is 180°C (thermostat 6), which works as a reliable default for pavé de saumon. Multiple sources cite this temperature as the sweet spot between cooking the fish through and keeping it moist.

Common temperatures from recipes

MOWI Salmon FR confirms that 160-180°C covers the standard range for oven-baked salmon, with 180°C being the most frequently cited figure across twelve verified sources. If your oven runs hot, 160°C still produces good results with slightly longer time.

180°C vs higher options

Here.fr reports that 6-7 minutes at 200°C produces a mi-cuit (rare) finish, while 10 minutes at the same temperature reaches à cœur (fully cooked). SOSCuisine recommends 10 minutes at 215°C for a 2-2.5cm thick filet — higher heat means faster cooking, but the margin for error shrinks.

Thickness impact

Vanessa Cuisine specifies that a pavé 2.5cm thick needs exactly 10 minutes at 180°C. Thicker pieces need more time, thinner ones need less — the rule of thumb is 10 minutes per 2-2.5cm of thickness.

The implication: thickness matters more than weight. A thin 2cm piece weighs less than a thick 4cm piece of the same nominal weight.

How to cook salmon in the oven?

Oven baking salmon is straightforward once you have the temperature and time locked in. The method you choose — direct baking versus papillote — affects both cooking time and moisture retention.

Step-by-step basic method

• Remove salmon from refrigerator 20-30 minutes before cooking (Vanessa Cuisine recommends this for even cooking)
• Preheat oven to 180°C with conventional or fan-assisted setting
• Place pavé on a baking dish or sheet, skin side down if skin is on
• Bake for 10-15 minutes depending on thickness
• Let rest 2 minutes before serving — the fish continues cooking internally

Prep with skin or skinless

Skin-on salmon protects the flesh during baking and makes flipping easier if you need to sear the skin side briefly. Skinless pavés cook slightly faster since there’s no protective layer.

Foil or direct bake

Le Restaurant 24 notes that papillote (en papillote, or foil packet) keeps salmon moister than direct baking because steam circulates inside the sealed packet. Papillote takes 20-30 minutes at 180°C versus 10-15 minutes for direct baking.

The catch: papillote is slower but more forgiving — you can leave it in a few extra minutes without the same drying risk.

What cooking time for fish in the oven?

Cooking time depends on weight and thickness. The weight-specific chart from Papilles et Pupilles gives the most granular guidance:

Weight	Time at 180-200°C	Source
120g pavé	8 minutes	Papilles et Pupilles
150g pavé	9-10 minutes	Papilles et Pupilles
200g pavé	11-12 minutes	Papilles et Pupilles
1kg filet	15-18 minutes	Papilles et Pupilles

The pattern across the weight chart shows roughly 1 additional minute per 30-40g of salmon at standard oven temperatures.

Avoid overcooking signs

Du Bocal à la Gassiette warns that salmon continues cooking after you remove it from the oven. The flesh should look slightly rosé at the center when you pull it out — it will firm up during resting.

If the flesh looks completely opaque and flakes easily with a fork, you’ve already crossed into dry territory.

Rest after baking

A 2-minute rest allows juices to redistribute. Cover loosely with foil to keep warm without continuing to cook. This step is especially important for thicker fillets where carryover cooking is more pronounced.

What is the perfect cooking for salmon?

“Perfect” depends on your preference for doneness. French recipes generally accept three levels:

• Nacré (pearly/rare): 7-8 minutes at 210°C — translucent center
• Mi-cuit (half-cooked): 6-7 minutes at 200°C — slight translucency remains
• À cœur (fully cooked): 10 minutes at 200°C — opaque throughout

Juicy vs dry prevention

The universal tip across sources: never exceed 15 minutes at 180°C for standard pavé. Le Restaurant 24 puts it bluntly — “le vrai piège du saumon au four, c’est le dessèchement” (the real trap with oven salmon is drying out).

Internal doneness check

An instant-read thermometer eliminates guesswork. Insert into the thickest part of the fish — for mi-cuit, aim for 45-50°C; for à cœur, 50-55°C. This method works regardless of thickness or starting temperature.

Variations like honey or lemon

Add glaze or aromatics after 8-10 minutes to avoid burning. Honey-based glazes caramelize quickly at high heat — either finish at 200°C for 2-3 minutes or switch to broil for the last minute, watching constantly.

What this means: timing shifts slightly when you add wet ingredients or glazes, but the core 10-15 minute window at 180°C remains valid as your baseline.

How to cook a salmon fillet?

A fillet is larger than a pavé, so it needs more time. SOSCuisine recommends 10 minutes at 215°C for a 2-2.5cm thick filet, but for standard household ovens at 180°C, expect 15-18 minutes per kilogram.

Pavé specific tips

• Press a thin lemon slice onto each pavé before baking — acid firms the surface slightly
• Center rack position ensures even heat distribution
• For fan-assisted ovens (chaleur tournante), reduce time by 1-2 minutes

Skin on benefits

The skin acts as a natural buffer, preventing the flesh from direct heat contact. It also shrinks less during cooking, helping the piece hold its shape. Score the skin lightly if you’re concerned about curling.

Recipe ideas

Marmiton’s classic recipe uses thermostat 6 (180°C) with white wine and lemon for 25 minutes total. Here’s.fr offers a honey-mustard glaze version. For something different, MOWI Salmon FR’s salt crust method (saumon en croûte de sel) requires 40 minutes at 200-210°C for whole fish — but this is a different technique entirely.

The trade-off: pavé works for weeknight meals (10-15 min), while whole fillets or en croûte de sel demand more planning and time.

What this step-by-step sequence delivers: consistent results whether you’re cooking a single pavé or doubling the recipe for a family dinner.

Le vrai piège du saumon au four ? Le dessèchement.

— Le Restaurant 24 (Recipe publication)

La cuisson du saumon au four est un grand classique et sans doute la façon la plus simple de réussir à coup sûr sa recette.

— MOWI Salmon FR (Salmon producer)

Il est important de ne pas trop cuire le saumon pour éviter qu’il ne devienne sec.

— Vanessa Cuisine (Food blogger)

For home cooks, the oven salmon decision is straightforward: 180°C for 10-15 minutes, pull early rather than late, and rest before serving. The sources that matter most — MOWI, Papilles et Pupilles, Marmiton — all converge on these numbers. The risk isn’t undercooking; it’s that 2-minute overcook that turns silky fish into chalk. A thermometer removes the guesswork entirely, targeting 50-55°C for fully cooked or pulling at 45°C for mi-cuit.

Frequently asked questions

Is salmon better with skin in the oven?

Skin-on salmon protects the flesh from direct heat, helps the piece hold its shape, and prevents sticking. It also crisps slightly if you sear the skin side briefly after baking. Skinless is fine for thinner cuts or recipes where you want the skin removed before serving.

Can I use foil for salmon packets?

Yes. Papillote (sealed foil or parchment) creates steam inside the packet, keeping salmon moister than direct baking. Papillote for pavé takes 20-30 minutes at 180°C versus 10-15 minutes for direct baking. The trade-off is longer time but more forgiveness — you can leave it in a few extra minutes without drying out.

What if salmon is still pink inside?

If the center looks translucent, it’s likely mi-cuit (half-cooked) — a preference, not a safety issue if the fish is fresh and properly stored. French recipes often target this doneness. If you prefer fully cooked, return to the oven for 2-3 minutes and check again. The fish firms up as it continues cooking during the rest period.

Does oven salmon work for frozen fish?

Frozen salmon requires adjustment — add 2-3 minutes to cooking time and ensure the fish is fully thawed before baking for even results. Some sources don’t fully standardize these adjustments, so using a thermometer is the most reliable approach.

Air fryer vs oven for salmon?

Air fryers work well for salmon with shorter cooking times (8-10 minutes at 200°C) and similar results to oven baking. The advantage is less preheating time and more controlled heat. The trade-off is smaller capacity — air fryers handle 1-2 pavés, while an oven accommodates larger pieces or multiple portions.

Best sides for oven baked salmon?

Lemon-dressed vegetables, roasted potatoes, or a light salad pair well. The 12-15 minute cooking window for salmon also works for roasting vegetables at the same temperature if you use a multi-level oven rack.

How to check salmon doneness?

The most reliable method is an instant-read thermometer: 45-50°C for mi-cuit, 50-55°C for à cœur (fully cooked). Visual cues work too — the flesh should look slightly translucent at center for mi-cuit. Avoid pressing with a fork; gentle pressure tests texture without breaking the flesh.
