How Long Does It Take to Bake Salmon?

Quick Answer

A standard salmon fillet (1–1.5 inches thick) bakes in 12–15 minutes at 400°F (200°C). The USDA recommends cooking salmon to an internal temperature of 145°F (63°C), measured at the thickest part. Thinner fillets may be done in as few as 8–10 minutes, while thicker center-cut pieces may need up to 18–20 minutes.

Baking Times by Temperature and Thickness

Oven Temp	Thin Fillet (0.5–0.75 in)	Standard Fillet (1–1.5 in)	Thick/Center-Cut (1.5–2 in)
350°F (175°C)	12–15 min	18–22 min	22–28 min
375°F (190°C)	10–12 min	15–18 min	18–22 min
400°F (200°C)	8–10 min	12–15 min	15–20 min
425°F (218°C)	7–9 min	10–13 min	13–17 min
450°F (230°C)	6–8 min	8–12 min	12–15 min

How to Tell When Salmon Is Done

The most reliable method is using an instant-read thermometer:

• USDA minimum safe temperature: 145°F (63°C)
• Medium-rare (preferred by many chefs): 120–125°F (49–52°C)
• Medium: 130–135°F (54–57°C)

Without a thermometer, look for these visual cues:

• The flesh flakes easily when pressed with a fork
• The color changes from translucent to opaque pink throughout
• White albumin (protein) appears on the surface—a small amount is normal

Factors That Affect Baking Time

• Fillet thickness: The single biggest variable. Always measure at the thickest point
• Skin-on vs. skinless: Skin-on fillets may take 1–2 minutes longer as the skin insulates
• Starting temperature: Room-temp salmon (rested 15 minutes) cooks more evenly than fridge-cold
• Covered vs. uncovered: Foil-wrapped salmon steams faster and stays moister—reduce time by 2–3 minutes
• Oven accuracy: Use an oven thermometer to verify your oven’s actual temperature

Step-by-Step: Oven-Baked Salmon at 400°F

1. Preheat your oven to 400°F (200°C)
2. Pat the salmon dry with paper towels and season with salt, pepper, and olive oil
3. Line a baking sheet with parchment paper or foil for easy cleanup
4. Place salmon skin-side down (if skin-on) on the prepared sheet
5. Bake for 12–15 minutes until internal temp reaches 145°F
6. Rest for 2–3 minutes before serving—carryover cooking will add 3–5°F

Popular Baking Variations

Method	Temp	Time	Notes
Foil packet	400°F	10–12 min	Traps steam; great with vegetables
En croute (puff pastry)	400°F	20–25 min	Pastry adds cook time
On a cedar plank	400°F	15–18 min	Soak plank 1 hour first
With a glaze	400°F	12–15 min	Apply glaze in last 3–4 minutes

Tips for Perfectly Baked Salmon

1. Choose center-cut fillets for the most even thickness
2. Remove from fridge 15 minutes before baking for even cooking
3. Don’t overcook—salmon continues to cook after leaving the oven
4. Check doneness at the minimum time listed and add minutes as needed
5. Use a light coating of oil to prevent sticking and keep the surface moist
