Baking salmon is one of the easiest and most foolproof ways to get tender, flaky fish with minimal effort. But the key to perfect baked salmon lies in the cooking time—too short, and it’s undercooked; too long, and it becomes dry and tough.
In this guide, we’ll break down how long to bake salmon at different temperatures, factors that affect cooking time, and how to get that perfect doneness every time. Whether you're making a simple salmon dish or trying our Baked Salmon with Butter Lemon Sauce, this guide will ensure your salmon turns out perfect!

Ideal Baking Times for Salmon at Different Temperatures
1 At 425°F (218°C) – Quick & Crispy
- Time: 8-12 minutes
- Best for: Thin fillets (½ inch or less), skin-on salmon, and quick meals
- Tip: This high temp gives the salmon a lightly crispy top while keeping the inside moist.
2 At 400°F (200°C) – The Perfect Balance
- Time: 12-15 minutes
- Best for: Most fillets (¾ to 1 inch thick)
- Tip: A great balance of tenderness and crispiness, making it ideal for recipes like Baked Salmon with Butter Lemon Sauce.
3 At 375°F (190°C) – Slow & Even Cooking
- Time: 15-18 minutes
- Best for: Thicker salmon fillets (1 inch or more)
- Tip: If you prefer gently cooked, ultra-moist salmon, this is the best temperature.
4 At 350°F (175°C) – Low & Tender
- Time: 18-22 minutes
- Best for: Large whole salmon fillets, skinless salmon, or meal prep
- Tip: Cooking at this temp keeps the salmon extra soft and moist, but won’t give you crispy edges.
Factors That Affect Baking Time
Several things can change how long your salmon takes to cook:
✅ Thickness of the Fillet: Thin fillets cook faster, while thicker fillets (1 inch or more) take longer.
✅ Skin-On vs. Skinless: Skin-on salmon takes slightly longer but helps lock in moisture.
✅ Fresh vs. Frozen: Frozen salmon should be thawed first or baked for an additional 5-7 minutes if cooking from frozen.
✅ Bone-In vs. Boneless: Bone-in salmon may require an extra 2-3 minutes of baking.
How to Check If Salmon is Done
The best way to avoid overcooked or undercooked salmon is to check for doneness using one of these methods:
✔️ Use a Meat Thermometer (Best Method!)
- Salmon is perfectly cooked when the internal temperature reaches 125-130°F (52-54°C) for medium doneness.
- For well-done salmon, aim for 140°F (60°C).
✔️ Fork Test
- Gently press a fork into the thickest part of the salmon.
- If it flakes easily and looks opaque, it's done!
✔️ Visual Cues
- Raw salmon is bright pink and translucent.
- Cooked salmon turns opaque and light pink.
Pro Tip: If in doubt, remove salmon a minute or two early—residual heat will continue cooking it as it rests.
Can You Overcook Salmon? (Yes! Here’s How to Avoid It)
Overcooked salmon turns dry and tough, losing its delicate, flaky texture. Here’s how to avoid overcooking:
❌ Don’t bake too long – Stick to recommended times based on temperature and thickness.
❌ Check temp early – Start checking at the lower end of the time range to prevent drying out.
❌ Let it rest – Once out of the oven, let salmon sit for 2-3 minutes before serving—this helps redistribute juices.

FAQs: How Long to Bake Salmon?
If baking salmon wrapped in foil, it typically takes 15-20 minutes at 375°F (190°C). The foil locks in moisture, making the salmon extra juicy.
Baking salmon with skin takes the same amount of time as skinless, but leaving the skin helps retain moisture and prevents sticking.
You can bake frozen salmon without thawing at 375°F for 20-25 minutes, but for best results, thaw first and bake as usual.
Yes! Broiling at 500°F for 5-7 minutes gives salmon a crispy top while keeping the inside moist. Watch closely to prevent burning!
