Cooking salmon doesn’t have to be complicated. If you’re wondering how long to cook salmon at 350, you’ve landed in the right place. Baking salmon at 350°F is one of the most foolproof ways to achieve moist, tender, and flavorful results—whether you’re cooking fillets, steaks, or even frozen salmon straight from the freezer.
Let’s break down everything you need to know to cook salmon at 350°F like a pro.
Introduction to Baking Salmon at 350°F
Baking salmon at 350°F is a beloved method for both home cooks and professional chefs. Why? Because this temperature strikes a perfect balance—it’s hot enough to cook the fish evenly but not so high that it dries out.
Benefits of Baking at 350°F
- Ensures even cooking throughout the fillet
- Retains natural oils and moisture
- Allows flavors to infuse gradually
- Perfect for seasoning, marinades, or foil-wrapped methods
Why 350°F Is the Sweet Spot for Cooking Salmon
At 350°F, salmon has enough time to absorb flavors and remain juicy without overcooking. Unlike high-heat methods that can leave the fish dry, this temperature is gentle and forgiving—ideal for beginners or busy weeknights.
How Long to Cook Salmon at 350 in the Oven
Salmon Fillets (Skin-On vs Skin-Off)
- Skin-on fillets: 20–25 minutes
- Skin-off fillets: 18–22 minutes
- Thickness plays a role. A 1-inch thick fillet takes around 20 minutes.
Cooking Frozen Salmon at 350°F
- No need to thaw! Add 5–7 extra minutes.
- Cook for 25–30 minutes, covered in foil to retain moisture.
Whole Salmon or Salmon Steaks

Internal Temperature: The Key to Perfect Salmon
The USDA recommends an internal temperature of 145°F for cooked salmon. However, many chefs pull it out at 135°F, letting carryover heat finish the job.
How to Check Temperature
- Insert a food thermometer into the thickest part
- If it flakes easily and turns opaque, it’s likely ready
